Humans vs. Zombies: Athens, referred to as HvZ, is part of Ohio University’s Urban Gaming League, a group that brings students together to play in large-scale, real-life, urban settings.
HvZ is a nationwide game played at college campuses. HvZ is a modified version of tag: there is the zombie team and the human team. Players from the zombie team “infect” players from the human team. Humans are tagged via nerf gun or a sock bomb, a balled-up sock covered in duct tape. Once all humans are tagged, the game is over.
“You haven’t played HvZ unless you’ve played an Athens game...”-Rob McMillan
HvZ is played 24/7, excluding safe zones. Games have set start dates and end dates, Zack Kolumban, an HvZ administrator, said. Games can last from one day to a week.
“We try to pace the game to last the set amount of time,” Kolumban, a senior studying media arts and studies, said. “As the turns are happening, we funnel the amount of turns to make sure the game lasts the entire time.”
HvZ employs lots of costuming.  Players are often all geared up in army-style garments. Though sometimes realistic, costuming is usually made by the players themselves.
“(Players) have their own equipment they use personally,” Kolumban said. “The staff gear is mostly DIY.”
Though HvZ is a game started by and for students, anybody can play. Local non-students play in HvZ: Athens, Kolumban said.
It can be a little jarring to see students run around decked out in full-body army suits and holding nerf guns. But over the past decade, people usually know what’s going on, Kolumban said. Sometimes onlookers join mid-game.

Members of Humans vs. Zombies: Athens stand in formation as they prepare to defend themselves from a "zombie" on Tuesday, Feb. 11, 2020.
As well as letting passers-by in on the action, HvZ also communicates with the Athens Police Department and OU Police Department to let them know what to expect.
“I go into APD and OUPD and give them the dates and times and contact info,” Kolumban said. “They already know the drill.”
Though communicative with local authorities, HvZ sometimes faces unexpected situations.
During Sibs Weekend, HvZ was supposed to play on College Green, but an event with police officers occupied the space, calling for a quick change of plans, Kolumban said.
“We just said we’ll go to West (Green). We don’t have to go to College Green,” Kolumban said.
As an administrator, Kolumban is the go-to person for when something goes wrong. He’s there to help out in times of crisis, from last-minute change of plans to mediating conflicts.
“I monitor everything that's going on,” Kolumban said. “I’m the first response in (the) event of an emergency — the first person who’s there to figure out what's going on.”
The game has changed a lot over time, Jeremy Hayes, who has been with HvZ: Athens for about a decade, said. A combination of things have pushed evolution in the game.
“The nerf blasters were much more inferior,” Hayes said. “It’s gone downhill in attendance.”
When Hayes first started playing HvZ, the group consisted of 200 to 300 people. His first game had 320 participants, he said.
“Everyone was coming out,” Hayes said. “People had a lot more fun being a zombie.”
The more advanced the nerf guns have become, the easier it is to tag more people in the game.
“As blasters got better, people got disinterested,” Hayes said.
Nevertheless, people still join, Hayes said. Whenever he’s out playing, he’s ready to recruit.
“I always have extra (supplies) if someone wants to join,” Hayes said.
HvZ is for anyone, Hayes said.
“It’s for kids and nerds alike.”
Rob McMillan was one such child. He joined HvZ: Athens when he was only 9 years old. McMillan, now a junior studying sales, has noticed changes in HvZ, too. Back then, everything was a bit more “real.”
“People got really into character,” McMillan said. “As a 9-year-old, as far as I was concerned, that was the apocalypse.”
McMillan has found some of his best friendships in HvZ. This semester, he ran past Ryan Doyle, a sophomore studying music education, as he was playing HvZ on East Green. Though it’s only been a couple weeks, they’re now best friends.
“I was going up Morton and (McMillan) goes: ‘Hey, man. Trying to shoot some zombies?’” Doyle said. “I’ve probably done eight missions now.”
For McMillian, Athens is an extraordinary place in general, but to play HvZ here is something totally special.
“You haven’t played HvZ unless you’ve played an Athens game,” McMillan said.
For those who want to get involved with HvZ, stay up to date with the group’s Facebook page. The next event will be Feb. 28-29.

Hilary and Jackie (1998)
Director: Anand Tucker Cast: Emily Watson, Rachel Griffiths, James Frain, David Morrissey, Charles Dance, Celia Imrie Screenplay: Frank Cottrell Boyce Producers: Nicolas Kent, Andrew Paterson Runtime: 120 min. US Distribution: October Films Rated R: language, sexuality, disturbing images
Copyright 1998 Nathaniel R. Atcheson
Hilary and Jackie is about two musician sisters and their lives together. As a child, Hilary du Pre (Keeley Flanders) is a phenomenal flautist who overshadows her cellist sister, Jackie (Auriol Evans). The girls love each other very much, but Jackie doesn't like the competition aspect of their lives, forced upon them by their mother (Celia Imrie). So, she quickly masters her instrument, making it clear to everyone that she is a musical genius. Soon, Jackie is the focus of everyone around her.
Inevitably, the girls grow into young women; Jackie (played by Emily Watson as an adult) is now performing solo recitals, but Hilary (Rachel Griffiths) is struggling with her flute lessons. From that point, the film shows us the next twenty years from the perspective of both women. We first see Hilary's life, in which she meets and falls in love with Kiffer Finzi (David Morrissey). The last third of the film is told through Jackie's eyes, and we see her rise into stardom and her decline into multiple sclerosis.
Hilary and Jackie is one of the most masterful films of 1998. Not since The Truman Show have I seen a film that so flawlessly integrates skillful acting, lush cinematography, and a wonderful story into a satisfying, moving motion picture that will resonate in memory long after the credits roll. But it's not just an exercise in good film making -- Hilary and Jackie has a beautiful emotional core that shows us a fascinating relationship between two extremely interesting women.
The first element that most moviegoers are likely to notice is the scenery and cinematography. The film was directed by Anand Tucker, a man who clearly understands that the image on screen needs to be as powerful as the contents of the story. Along with David Johnson's superb cinematography, Tucker has made a film of immense visual wealth. The colors are vibrant and vigorous; later in the film, when Hilary is living in the countryside, the way Johnson photographs the huge, sprawling fields and rolling hills of wildflowers is truly breathtaking. Also notable are the scenes in which Jackie performs the cello -- the passion that emanates through the instrument bursts out of the screen, making every such scene an exciting, visceral experience.
Of course, much of the excitement comes from Emily Watson's performance. Here is a woman who has made three films, and in those three films has proven a range of acting that most experienced actresses will never show. Her first starring role, in Breaking the Waves, earned her an Oscar nomination, and I sincerely hope that she earns the same honor for Hilary and Jackie. I don't know if Watson can really play the cello, but she does a perfect job of pretending in the scenes that require her to perform. But what I really admire about Watson -- and about the entire film, for that matter -- is her emotional honesty. I got lost in her performance, lost in the fact that I was watching someone act.
Rachel Griffiths shows just as much skill as Watson does, even though she doesn't have quite as much material to work with. The film is based on the book A Genius in the Family, written by Hilary and Piers du Pre (it's all based on a true story, just in case you didn't know); the picture could have easily focused on Jackie, and made the relationship a side note in the story. I'm glad that screenwriter Frank Cottrell Boyce chose not to do this, though, since the relationship between Jackie and Hilary is what makes the film so fascinating: even through all the competition, the two women never stop loving each other. It's one of the most layered, moving relationships to emerge from any film this year. In a year in which so many films have regurgitated themes and images that we've all seen countless times before, the people behind Hilary and Jackie have brought us a visually and emotionally profound film -- a piece of cinematic art that I will never forget.

Mushrooms - P. cubensis
My first time with mushrooms and definitely not the last. I've had experience with weed and sally d.
I ate the candy about 5 o’clock – with 20 minutes left in class. I was expecting a come on time of around 45 minutes, so I should start feeling the effects a little after my 15 minute walk home. Class continued to drag on, the subject was interesting, but my attention was on the purple foil and wax paper that had wrapped the chocolate I just consumed. It tasted somewhat funny – like old, cheap chocolate. I wondered about the path it took to get to me. Rumor has it they came from California – that’s a long way for chocolate mushrooms to travel in the United States. After that, they probably were passed through a few dealers down to the guy my friend bought it from. A man I’ve never met, but a man that helped open my eyes nonetheless.
My walk home seemed quick, it was a beautiful day and I was looking forward to the experience ahead of me. Would I see melting shoes, breathing walls, visit alien worlds, and smell colors? I was nervous with excitement. Arriving home to my small apartment, I turned on the Simpson’s, as I always did after class, and sat down to await my first effects. I felt restless, like something should be happening. I was growing hungry. I decided I should probably eat now, so I wouldn’t have to disrupt my experience later in the night. I made some rice with broccoli, and ate a small plate.
I went back for seconds, but didn’t make it. I was consumed with laughter. My own, pure, unadulterated laughter. I wasn’t laughing at anything in particular, just laughing to laugh. The sound of my laugh made me giggle, my giggle made me snort, and my snort made me burst into an uproarious laugh.
I turned off the Simpon’s because I found it oddly distracting and not funny. Strange I thought, me finding the Simpson’s boring. I lay down on the couch to relax, it had been a stressful weak. Staring at the ceiling I hoped to see some kind of visual effect since the mushrooms were obviously in my system. I was disappointed by the normal ceiling staring back at me. I closed my eyes and felt my body turn into jelly. I was so relaxed. I started to see patterns on my eyelids. They were very faint – red, green, and blue – worm like structures. They were wiggling, snaking, and contorting themselves in front of me. They felt natural; they should be there. It was as if I was looking into the building blocks of life itself. They started to form helixes twisting around each other and blending to into two long red, green, and blue dotted strains, swirling around each other.
I opened my eyes and was overwhelmed by the desire for some chocolate. Another very strange feeling for me. I never crave chocolate. I searched around my apartment for a minute, realizing I had none, I pondering going outside. The sun was starting to set. It was the hour when everything is orange and red outside. I figured it would be a good idea to venture out and see the world.
I threw on a hoodie and set out on my trip to the gas station to purchase some Hostess Cupcakes, which I was now craving like nothing I ever had before. It was beautiful out; everything had that sun-orange glow to it. The closer I got to the station, the stranger I started to feel. It seemed I shouldn’t be wearing shoes, shouldn’t be living in the concrete world, and shouldn’t be going to a corporate environment. I arrived at the station and went inside. A black man was working, stacking beer, he was singing and dancing with the radio and looked completely happy. The fact that he was so happy, so joyous, even though he was working made me smile with all my soul. I found the cupcakes I had been craving, purchased them from the man and was on my way.
I felt as though I was carrying so much more than cupcakes. I wanted to rip them open and devour them on the spot. I decided I should wait because it would make them so much better. I wanted to sit out on the patio and eat them under the setting sun. About half way home I couldn’t resist any longer. I opened the package and in two huge bites ate the first one. I waited to eat the second one.
Arriving back at my apartment, I went to the patio and sat on the brick wall. I ate my cupcake, felt the sun warming every cell on my face, and stared down at the Aztec patterns in the stones of patio. I wanted to be an Aztec, without a doubt they knew the power of these mushrooms and so much more. An ancient civilization that knew so much more than we know now.
I went back into my apartment and turned out the lights. The only light was a low red glow coming from the window. I decided to eat some more rice so I filled my plate back up and put it in the microwave. While waiting for it to heat, I realized I was seeing trails on my hands. The microwave was done, so I sat down and started to eat the rice.   I put down the fork and started to use my fingers. This made the food taste even better. I stopped about half way through the plate because I was feeling full. While looking down at the plate half full of food, it started to breathe. It had come alive and was breathing.  It felt good to be there, a warm feeling.
I put some music on, Buddha Bar III, and laid back down on the couch and closed my eyes. Again I saw the spirals, but this time there were more. I was seeing a pair of beautiful female eyes with them. At first just a flash here and there, but then they became steady, intertwining with the spirals. I came to realize after a few minute of studying them that they were not just any eyes. They were they single most important eyes I had ever seen, they were the eyes of the Goddess of Creation. She was watching me, she was always watching me, and still is. She watches all of us, for we are all her creation and dearly beloved by her. She has a complete and utter care for each and every one of us and our well-being.
I began to feel her presence with me after a few minutes. She was standing over me, studying me. She felt all my sicknesses, my pains, my stress, and my happiness. She understood them more than I did. She began to wave her hands over me and I felt a warmth coming down from them. She was healing me with Qi-Gong energy work.  She was burning something out of me, something bad. I felt a strong heat over my right-top side. Then she moved on. I had been cured, of what I didn’t know, but I felt better and cleaner. My head was cleared.
After I received the energy work from the Goddess of Creation, I felt very liberated. I started thinking about my surroundings and my environment, and my thoughts drifted to the ground beneath my feet. The earth! It was there for me! It always had been and always will be. We make our living off the earth, everything comes from the earth, and eventually everything goes back to the earth. Everything, from plastic sporks to rocking chairs to jetliners come from the earth. Without her, we have nothing. I started communicating with the earth on a spiritual level. I could hear her pains, joys, and sorrows – We are killing our mother earth – from which we are all born. I could see and feel the earth in front of me and I reached my arms out and embraced her. Mother earth began to sob on my shoulder, I could feel the tears, nearly breaking down into tears myself.
They were the tears of a forgotten mother, a mother who had lost touch with her children.  We offer no thanks, no gratitude, nothing for the one that gives us EVERYTHING we have.
I started focusing on the back of my eyelids again. I still had my arms up from hugging the earth. I could see my arms through my eyelids. I moved them, and the image of them moved too, right in sync. This was astounding to me.
I got up to use the bathroom. As I stood in nearly complete darkness, I closed my eyes while I peed. I was transported to another time, an ancient time, and another place. I stood in the darkness of the night with only the light of the moon over a damp green pasture. I was naked and free. The air was clean and fresh. My mind was unpolluted with the worries of modern times – no information overload.
I finished and zipped up. I went and sat on the couch to ponder my experience in the bathroom. When I sat down, my position flashed me back to early China. I was a very old, very respected man. My children looked up to me and my wife was deceased. I missed her and loved her very much. I could feel my old wrinkled face and leathery hands.  I could feel my time drawing near and as I looked back on my live, I felt full of pride and happiness. I had hard time, many of them, by between those times I was happy with a healthy loving family.
I laid back down on my couch and watched my hands moving through my eyelids again. I became restless on the couch and wanted to be closer to the earth. I moved from the couch to the floor of my apartment. I was lying right next to the speaker and all I could hear were the luscious tones of Buddha Bar. I closed my eyes and drifted into another time.
I was curled up next to my wife on a deerskin; we were shivering. I looked around; we were in a teepee gently lit by a small fire. I was cold and I could smell the snow on the ground. I got up, stretched, and went outside. The air was so crisp and stinging in my lungs. I took a big breath and held it in. I felt worrisome about the white men from Europe. We had been battling with them for the last few months and defeat was evitable. We had already been pushed back from the coast. The way they live was just not right. They had no respect for the land that feeds them.
As I drifted back to the now, the music began to reverberate in my ears. I could feel the pulsing beat in my chest. I stood up and started moving to the music. My moves turned into dances and the dances took over my head. I danced like a fool, for a good thirty minutes with no one watching by the Goddess of Creation.

Red Butte Garden is a sactuary for native bees. Joe Wilson, a professor of Entomology at Utah State University, studied the bee fauna of the Garden in 2015-16 and discovered 127 different species of bees, from 33 different genera, and all six North American bee families. Learn more about the bees in Red Butte Garden.
Because there are so many native bees and other pollinators in the Garden, our plant conservation team, led by Dr. Sarah Barlow, was able to conduct a successful 2017 pilot pollinator study using RANA, an automated, motion sensitive, time-compressed digital video system. Learn more about Rana.

View of medieval Swansea from the south |
View north from Wind Street towards the Castle (Lorenzo Caravaggi) |
One of the key aims of the City Witness project has been to reconstruct the urban landscape of medieval Swansea, and to explore the sight-lines of witnesses to the hanging of William Cragh within the medieval town.
Computer-generated visualisation of historic landscapes and buildings remains a controversial area in academic research. While virtual reconstructions of past places can help us to engage imaginatively and immerse ourselves in history, there is also the potential for them to go beyond the evidence base we have, to introduce assumptions or clichés about the medieval past, and to obscure the scholarly processes – and hypotheses – by which they were produced. Agreements such as the London Charter have attempted to find a model of ‘best practice’ for the production of visualisations based on scholarly research.
Visualising medieval Swansea is a challenge. Very little evidence survives for the appearance of its early buildings. As City Witness is primarily an academic research project, it’s important that we only show what can be supported by the evidence itself. But the conservative, visually-simplistic renders produced by this method may be less engaging for many viewers. More creative, imaginative interpretations of the evidence (drawing on, for example, analogy with other towns where medieval buildings do survive) can offer an alternative, more visually arresting view.
Our solution has been to embrace the idea of multiple, varying perspectives which is foregrounded by the medieval witness statements themselves. On this page you can see a variety of different views of medieval Swansea:
1. Schematic views, showing what we can recover from the archaeological evidence (via our GIS research), but with little imaginative addition
2. Interpretative views, also based on our GIS research, but with some imaginative extension
3. Freer artistic views, loosely based on our GIS research (these images are also the basis for medieval Swansea in our interactive Game)

Reference
Configuration settings are stored at the global scope under the "global.C" object and accessed via "global.C.KEY_NAME"
var sh = require(global.C.BASE_DIR + "/lib/shutil.js");
At startup ShellyJS will look for a directory named "config" in the shellyjs install directory "./node_modes/shellyjs/config"
This is typically overridden by passing in "CONFIG_DIR" to the shellyjs.start function.
shelly.start({ CONFIG_DIR: __dirname + "/config" });
Configuration values are set via the following in priority order:
global.CDEF("KEY", <VALUE>): Define if not yet defined. Value can be any valid variable type.
global.CFDEF("KEY", <VALUE>): Force the define even if defined already.
To keep things segmented well you can chain your "main.js" configuration file to the default one like:
global.CDEF("MODULE_CACHE", false); global.CDEF("CLUSTER_NUM_SOCKET", 1); // pick up all the other default configs require(global.C.BASE_DIR + "/config/main.js");

The API modules are created in directories under APP_API_DIR directory set in the configuration. The directory and file names are important as they are used to define the calling signature of the api.
If you wanted to call a function "example.hello" you would create the file "~/apis/example/example.js". Assuming the APP_API_DIR is set to "~/apis". This API will then show up under the "App APIs" tab in the admin and be available via REST, WebSocket, and TCP interfaces.
<API_MODULE>.desc: type: string, simple description of what API does (displayed in admin)
<API_MODULE>.functions: type: object, list of commands that the API supports
Each function is a defined as a member of the object with the value being an object with the list of options.
<API_MODULE>.functions.<COMMAND>.desc: type: string, short discription of what this command does
<API_MODULE>.functions.<COMMAND>.params: type: object, members are the parameters required by the command
<API_MODULE>.functions.<COMMAND>.params.<PARAM_NAME>: type: object, member name is the name of parameter
<API_MODULE>.functions.<COMMAND>.params.<PARAM_NAME>.dtype: type: sting, javascript type for parameter (string, object, array, number, boolean)
<API_MODULE>.functions.<COMMAND>.security: type: array, list of strings that are the roles required to access this command
<API_MODULE>.functions.<COMMAND>.noSession: type: boolean, true if no session is required to access this command (defaults to false)
var sh = require(global.C.BASE_DIR + "/lib/shutil.js"); var example = exports; example.desc = "example api"; example.functions = { hello: {desc: "simple hello world api example", params: {}, security: []}, echo: {desc: "one parameter api example", params: {param1: {dtype: "string"}}, security: []} }; example.hello = function (req, res, cb) { res.add(sh.event("example.hello", "world")); return cb(0); }; example.echo = function (req, res, cb) { res.add(sh.event("example.echo", req.body.param1)); return cb(0); };
Line 1: Not required but has helper functions like sh.event and sh.error provide a consistent envelope for responses.
Line 3: All members of "example" are exported.
Line 5: Set the general descriptions for the module.
Line 6-9: Function definitions that are to be used in the API as commands
Line 7: Simple "hello" command that takes no parameters
line 8: "echo" command that takes one parameter "param1" that must be a string
Line 11: Implementation of the "hello" function that is passed the request (req), response (res), and callback (cb) arguments
Line 12: Add an message to the response stream by calling "res.add()". Any object can be added and will be sent via JSON.stringify. These examples use the "sh.event()" function to provide a consistent envelope.
Line 13: Make the callback with "0" for no errors
Line 16-19: Implementation of the "echo" function
Line 17: Adds to the message to the response object by accessing the "param1" from the "request.body"
example.hello = function (req, res, cb) { res.add(sh.event("example.hello", "world")); return cb(0); }; example.echo = function (req, res, cb) { res.add(sh.event("example.echo", req.body.param1)); return cb(0); };
For anyone familiar with Express, this function signature should be familiar. When a command is sent from the client it gets processed and ends up with a call to the API command handler function declared in the module file. This function is passed a Request (req) object, a Response (res) object, and a callback (cb) function.
Given the API commands work against REST, WebSocket, and TCP interfaces only the following members should be used without checking the API type (req.api). The req and res objects under the REST interface have a super set of the member below and those found in Express. The WebSocket and TCP objects are similar.
This object holds all the information about the API command called from the client.
req.api (string): API the client command was issued against ("rest", "socket", "tcp")
req.session (object): Session object if valid.
req.session.user (object): Full user object for the current command. (See shuser.js)
req.session.uid (string): Short cut for user id req.session.user.get("oid")
req.session.valid (boolean): Is there a valid session for this request.
req.session.error (object): Error object with failure information if the session is not valid.
req.loader (object): Object that provides CRUD, locking, and caching for any ShObject subclass (see shobject.js)
req.body (object): Object that contains the parameters passed with the command.
req.env (object): Object for modules to use to pass information between pre, command, and post API module functions.
This object is used to return information to the caller. Responses are queued until after the call completes and any modified data is written back to the datastore - this is important to avoid any race conditions with notifications.
res.add(data (object)): queue an object to be sent back to the client JSON.stringified
res.flush(): send all data objects back to client
res.clear(): remove all data objects from the queue
res.notifyAdd(uids (array), data (object), exUids (string|array)): queue the data object to push to the list of uids if they currently have a Websocket or TCP connections. exUids are removed from the list before sending. exUids can be a single uid string or an array of uid strings. This handles the common case where res.add is sending the message back to the caller and you don't want to double send.
res.notifyFlush(): push all data objects to the target users
res.notifyClear(): remove all push data objects from the queue
cb(err, data): Function to call when done processing the command. If err is returned the command processor will stop processing the message, save any modified data objects, and flush any responses, notifications.
NOTE: error responses should be added via res.add as returning an err via the callback function will only stop command processing.
The following is a slightly more complicated example from the Object API:
object.get = function (req, res, cb) { req.loader.exists("kObject", req.body.oid, _w(cb, function (err, obj) { if (err) { res.add(sh.errordb(obj)); return cb(1); } if (obj === null) { res.add(sh.error("object-get", "unable to get object", obj)); return cb(1); } res.add(sh.event("object.get", obj.getData())); return cb(0); })); };

The fmcmc
R package provides a lightweight general framework for implementing Markov Chain Monte Carlo methods based on the Metropolis-Hasing algorithm. This implementation’s main purpose lies in the fact that the user can incorporate the following in a flexible way:
Automatic convergence checker: The algorithm splits the MCMC runs according to the frequency with which it needs to check convergence. Users can use either one of the included functions (convergence_gelman
, convergence_geweke
, etc.), or provide their own.
Run multiple chains in parallel fashion: Using either a PSOCK
cluster (default), or providing a personalized cluster object like the ones in the parallel
R package.
User defined transition kernels: Besides of canonical Gaussian Kernel, users can specify their own or use one of the included in the package, for example: kernel_normal
, kernel_unif
, or kernel_reflective
.
All the above without requiring compiled code.
While a lot of users rely on MCMC tools such as Stan (via the rstan package) or WinBUGS (via rstan), in several settings either these tools are not enough or provide too much for things that do not need that much. So, this tool is for you if:
You have a simple model to estimate with Metropolis-Hastings.
You want to run multiple chains of your model using out-of-the-box parallel computing.
You don’t want (or cannot) rely on external tools (so you just need good-old base R only for your models).
You want to implement a model in which your model parameters are either bounded (like a standard error, for example), or are not, say, continuous (e.g., a size variable in a Binomial distribution), so you need your own transition kernel.
In any other case, you may want to take a look at the previously mentioned R packages, or check out the mcmc R package, which also implements the Metropolis-Hastings algorithm (although with not all the features that this R package has), the adaptMCMC R package, or the MCMCpack R package.
In the following we show how to use the package for estimating parameters in a linear regression model. First, let’s simulate some data to use:
As you can see, in this case we have three parameters to estimate, the constant (2.0), the \(\beta\) coefficient (2.0), and the standard deviation parameter of the error (1.5).
To estimate this model, we can either maximize the log-likelihood function–which is what is usually done–or we could do it using MCMC. In either case, we need to specify the log(unnormalized some times)-likelihood function:
ll <- function(p, X., y.) {
joint_ll <- dnorm(y. - (p[1] + X.*p[2]), sd = p[3], log = TRUE)
joint_ll <- sum(joint_ll)
# If is undefined, then we explicitly return infinte (instead of NaN, for
# example)
if (!is.finite(joint_ll))
return(-Inf)
joint_ll
}
Notice that the function has more than 1 argument, in this case, p
, which is the vector of parameters, X.
and y.
, which hold the data of our model.
Let’s do a first run of the MCMC algorithm using the function of the same name (first, load the package, of course):
library(fmcmc)
# Running the MCMC (we set the seed first)
set.seed(1215)
ans <- MCMC(
ll,
initial = c(0, 0, sd(y)),
nsteps = 5000,
X. = X,
y. = y
)
As the output object is an object of class mcmc
from the coda
R package, we can use all the functions from it on our output:
##
## Iterations = 1:5000
## Thinning interval = 1
## Number of chains = 1
## Sample size per chain = 5000
##
## 1. Empirical mean and standard deviation for each variable,
## plus standard error of the mean:
##
## Mean SD Naive SE Time-series SE
## par1 3.126 0.1893 0.002677 0.03128
## par2 1.943 0.1234 0.001746 0.04176
## par3 4.093 0.0930 0.001315 0.01168
##
## 2. Quantiles for each variable:
##
## 2.5% 25% 50% 75% 97.5%
## par1 2.951 3.013 3.112 3.172 3.511
## par2 1.763 1.892 1.956 2.026 2.171
## par3 3.979 4.064 4.106 4.134 4.186
While the summary statistics look very good (we got very close to the original parameters), the trace of the parameters looks vary bad (poor mixing). We can re-run the algorithm changing the scale parameter in the kernel_normal
function. In order to do so, we can simply pass ans
as the initial
argument so that the function starts from the last point of that chain:
ans <- MCMC(
ll,
initial = ans,
nsteps = 5000,
X. = X,
y. = y,
kernel = kernel_normal(scale = .05) # We can set the scale parameter like this
)
plot(ans)
Much better!
Now, suppose that the algorithm actually takes a lot of time to actually reach stationary state, then it would be nice to actually sample from the posterior distribution once convergence has been reached. In the following example we use multiple chains and the Gelman diagnostic to check for convergence of the chain:
set.seed(1215) # Same seed as before
ans <- MCMC(
ll,
initial = c(0, 0, sd(y)),
nsteps = 5000,
X. = X,
y. = y,
kernel = kernel_normal(scale = .05),
nchains = 2, # Multiple chains
conv_checker = convergence_gelman(50) # Checking for conv. every 200 steps
)
## Convergence has been reached with 1000 steps (1000 final count of samples).
As a difference from the previous case, now we didn’t had to wait until the 5,000 steps were done, but the algorithm stopped for us, allowing us to start generating the desired sample much quicker.
For this final example, we will use the kernel
argument and provide what corresponds to a transition kernel which makes proposals within certain boundaries, in particular, we want the algorithm to propose only positive values for the sd
parameter, which we now must be positive.
More over, since we now from a fact that we will only get positive values, we can go further and modify ll
skipping the check for finite values:
Much simpler function! Let’s do the call of the MCMC function specifying the right transition kernel to increase the acceptance rate. In this example, we will set the max of all parameters to be 5.0, and the min to be -5.0 for the constant and 0 for the beta coefficient and the variance parameter, all this using the kernel_reflective
(which implements a normal kernel with boundaries) function:
set.seed(1215) # Same seed as before
ans <- MCMC(
ll,
initial = c(0, 0, sd(y)),
nsteps = 5000,
X. = X,
y. = y,
kernel = kernel_reflective(
ub = 5.0, # All parameters have the same upper bound
lb = c(-5.0, 0.0, 0.0), # But lower bound is specified per parameter
scale = 0.05 # This is the same scale as before
),
nchains = 2,
conv_checker = convergence_gelman(50)
)
## Convergence has been reached with 550 steps (550 final count of samples).
Again, as the proposal kernel has lower and upper bounds, then we are guaranteed that all proposed states are within the support of the parameter space.

This Figma exporter will export layer data as a standalone .json file. Importing this file into Ae is done by clicking Import 📎, or by dropping the file on the AEUX panel.
Design apps are able to work at a lower resolution for different pixel densities but Ae needs a fixed size. The size of the new comp is defined by the Comp size multiplier. When creating a new comp, a comp size multiplier dropdown will be visible.
When adding new layers to an existing comp, the current comp’s width is measured and used to define the comp size multiplier of the incoming artboard. The comp size multiplier will scale the new layers so the width of the artboard and the width of the comp match.
You may prefer rectangles and ellipses or you may love paths. Work the way you want with limited conversions.
By default, groups are created as invisible parent layers to the visible layers in the main comp. This option will automatically precomp these grouped layers. Precomps may also be ungrouped with the Grouping buttons.
(SKETCH only) Enabling this option will hide the Build button and create layers as soon as they are available using the other currently selected options.
Precomping avoids a long list of layers in a single comp but creates multiple inaccessible comps. It is now possible to precomp and un-precomp groups with a click.
Group layers are rectangle guide layers that do not render but can help transform multiple elements. Interacting with these is possible by switching layer visibility eyeball. Toggle all guild layer visibility with a click.
If groups aren’t your thing and you end up with a bunch of unnecessary layers, clicking will remove all guide layers from the comp.
Requirements: After Effects CC2014+ (2018+ for Figma image downloading)
If you follow all the instructions of the standard installation and AEUX still isn't showing up in the AE Window>Extensions menu you're gonna need to do a manual install. You didn't do anything wrong, it just happens sometimes wth extensions.


Nodebucket was developed as part the web-450 class taught by Richard Krasso at Bellevue University. Nodebucket is a task management web app that allows you to keep track of your daily tasks. This easy to use app consists of two columns: todo and done. You can add tasks to keep track of your todo items and drag them to the done column as you complete them. The tasks can be moved vertically to organize them based on priority. All of this wrapped in an user-friendly interface developed by yours truly.
To add a task, simply click on the add task button. To remove a task, simply click on the ellipse and select the remove option. And, organize the tasks based on priority, simply drag them vertically. After you have completed a task, you can drag it by holding down the mouse on desktops and pressing down on the task on a mobile device. Then, drop it on the done column. The app functionality has been tested both manually and with the use of SOAPUI. Nodebucket was created using the MEAN stack (MongoDB, Express, Angular, and Node.js). The front-end was developed using Angular, design material, CSS and HTML. Nodebucket sits on Heroku's cloud and was written using Visual Studio Code.


1. Requirements and Design¶
The broad requirements of the light weight driver program for FAST v8 are:
- the program should be very similar to how it would be used in NALU [naluDoc].
- the program should be capable of having a time step that is independent of FAST's time step.
- the program should have an option to turn off the structural modes in FAST.
- the program should be capable of instantiating multiple turbines inside FAST on the same processor core.
- the program should have a restart capability.
- the design of the program should allow a super controller to be built around all the turbines.
1.1. Meeting with Matt - 03/08/2016¶
I explained the general structure of the C driver program and how the current framework supports only one turbine per instance of FAST. The current FAST-SOWFA interface framework is:
- The framework supports an arbitrary number of turbines n.
- The FAST instances for turbines 1 through n are placed in processors 1 through n respectively.
- Global MPI reductions/broadcasts are used to transfer velocity and actuator force between FAST and the CFD solver.
Matt and I agreed that the current framework of using global MPI communications for each turbine may not scale well to large number of processors. The proposed framework for future CFD-FAST interface is:
- The new framework will have groups of processors within MPI_WORLD for each turbine.
- Each group will contain the CFD domain decomposition of all cells interacting with the turbine and the FAST instance.
- These groups of processors would communicate amongst themselves for all stuff related to that tubine.
- Ideally, the FAST instance for this turbine should be located within one of the processors that contain the CFD domain decomposition for that turbine. However, this is not a requirement. Adding 1 extra processor to this communication group shouldn't increase the total communication load. However, this might be an issue if the processor containing the FAST instance is not physically close to the other processors containing the domain decomposition within the MPI network.
- The domain decomposition/other pre-processing program for the CFD solver should be capable of identifying all processors that contain any cells that interact with the wind tubine. While this is possible in any software that we release, this would have to be a requirement for all external CFD software that want to interface with FAST in the future.
- The domain decomposition could happen in such a way that a processor interacts with two turbines that are close to each other. In this case, the framework could decide to place the FAST instance for both turbines on the same processor. This would require FAST to handle more than 1 turbine from C++. This can be avoided by requiring that the FAST instances for turbines 1 through n are placed in processors 1 through n respectively.
1.2. Meeting with Mike in lunch room - 03/08/2016¶
Mike continues to insist that the light weight driver program for FAST in C++ should be capable of running multiple turbines in 1 processor. However, we also discussed that the light weight driver program should be capable of running in parallel. So I have to figure out a way of incorporating it into the requirements and designing a test for it.
1.3. Super Controller requirements from Paul Fleming¶
Paul Fleming created a super controller [fleming2013] to control all the turbines in a wind farm inside SOWFA. The new driver program for FAST v8 should be designed such that it can be easily extended to include the super controller natively. Paul Fleming provided this rather long story about the development of the super controller using FAST v7 [fastv7] and what he envisions when using FAST v8 [fastv8ModFramework].
So, back when SOWFA was a FOA award, one of my first tasks was to implement the super controller inside of SOWFA. I wrote this up in the attached (admittedly not great) paper for EWEA. But at least, Figure 3 is helpful in explaining the architecture. I was working with the version of SOWFA in which FAST7 is coupled to openfoam. Working with John Michalakes, Matt, Sang and Pieter we did something like this:
- FAST can be set to call a compiled controller (usually referred to as Bladed-style since the interface is designed to match what BLADED expects and it’s convenient to use this well-known interface). You see this interface on the left of Fig 3.
- The next thing we did was make a new function called the “superController” which implements the wind farm control.
- Here’s where things got too technical for me and John really did everything.
- We made sure that there was always one more processor then we need for Openfoam, and then the super controller is some how made to exist there.
- Then the individual turbine controllers call the super controller by reference to the last MPI proc, and pass along a number so the super controller knows who is calling
- It may seem funny the turbine controllers call the super controller rather than the other way around, but we thought about this a lot and couldn’t really see any issue with this, who calls who seems more a software question without much impact on the controls.
Ok, finally, this all works, we’ve used it now for a ton of projects, it’s great!
Chapter 2, In which we meet FAST8
Ok, so then (1, 2 years ago?) there was a push to convert the FAST7 code to FAST8, including the super controller code. We had some initial discussions with Avi, Sang and Jason and Bonnie Jonkman, and one of the main outcomes was that the architecture shown in Fig 3 violates FAST8 conventions. As I understand, the individual turbine controllers talking to the super controller beyond FAST’s reach does not meet FAST’s modular framework. Therefore a new approach was agreed on, the super controller would exist basically to the left of Openfoam, openfoam would transfer the data from the super controller to each FAST instance, which would propagate the information to the individual controllers.
This approach had another nice benefit, FAST8 and openfoam have restart, and by having all the turbine and super controller states managed this way, could enable SOWFA + Super Controller to have restart too, which is awesome.
So this had been going on, Avi and Sang we’re doing the programming. In my understanding however, this effort ran out of money before it could be completed (or maybe it’s still ongoing?) Maybe good to check in with Avi and Sang.
And in the last bit of history, in the last few months, we in the controls group have begun using, in addition to SOWFA + Super controller, other versions of SOWFA. For example, the actuator disk version. We like this because, for example, to train FLORIS we need a lot of runs with the turbine operating in stationary but controlled way (like offset in yaw) and we can get way more data with the actuator disk against a coarse mesh grid. Also, certain partners would like to run SOWFA, and while the “main-line” SOWFA is easy enough to install, SOWFA + Super Controller may have only been successfully installed by John Michalakes, who left NREL some years back.
So, I hope all this has been helpful. If everything is on the table now, my plans for including the super controller would be:
- Make it an option in the main “SOWFA/NALU” distribution, not something that needs to be separately compiled
- Make it generic, able to work coupled to FAST, or AL or AD implementations
- Make sure it fits FAST8 module framework, and includes restart
- Make the individual turbine controllers, and super controller compiled separate, so they can be swapped out without recompiling SOWFA (not how we do it now, and that is too bad)
1.4. Design for testing¶
The C driver program should reproduce the same results as the native fortran program for the same input parameters. Since the C and fortran programs are compiled on the same machine, there should be no difference between the output from the two codes upto machine precision. The comparison of the output from the C and fortran driver programs will be done with the diff program. I will follow the design of the tests in NALU https://github.com/spdomin/NaluRtest.
1.5. Interface design¶
There are a few key differences between the C and fortran driver programs. These differences along with the testing procedure will dictate the design of the C driver program.
- The fortran driver program controls the time step of FAST directly, while the C driver program will control the time stepping of FAST externally. Thus, the C driver program should be aware of the start (tStart) and end (tEnd) time points and the corresponding time steps (ntStart and ntEnd), the time step (dtFAST), and the frequency with which the checkpoint files have to be written (nCheckPoint).
- The C driver program may suppply an additional number of parameters to FAST during initialization. These are defined in FAST_Types.f90 under the type FAST_ExternInitType
TYPE, PUBLIC :: fast_externinittype
REAL(DbKi) :: tmax = -1
INTEGER(IntKi) :: sensortype = sensortype_none
LOGICAL :: lidradialvel
INTEGER(IntKi) :: turbineid
REAL(ReKi) , DIMENSION(1:3) :: turbinepos
INTEGER(IntKi) :: numsc2ctrl
INTEGER(IntKi) :: numctrl2sc
END TYPE fast_externinittype
This suggests that the C driver program should have atleast the following variables:
double dtFAST;
double TMax;
float TurbinePos[3];
int TurbID;
char InputFileName[INTERFACE_STRING_LENGTH];
char CheckpointFileRoot[INTERFACE_STRING_LENGTH];
double tStart, tEnd;
double ntStart, ntEnd; // The time step to start and end the FAST simulation
int nCheckPoint;
int NumScOutputs; // # outputs from the supercontroller == # inputs to the controller == NumSC2Ctrl
int NumScInputs; // # inputs to the supercontroller == # outputs from the controller == NumCtrl2SC
This project is really about building an interface class to FAST. The driver program is really secondary and should simply use functions from the class. No one is actually expected to use the driver program as it is. The design of the interface class to FAST should be such that the driver program only contains simple calls as follows.
setInitialConditions() // Optional to state external initial conditions that don't belong in the input file.
init()
step()
end()
Everything else should be abstracted away into either input files or the functions themselves.
Thus, the variables listed above should be the variables in the C++ class. The same variables should be read in from an input file. Since we're following NALU's [naluDoc] footsteps, I propose that the input file to the C driver program/class be in YAML and read using yaml-cpp.


PORTRESERVE
Section: TCP port reservation utility (1)Updated: 1 July 2008
Index Return to Main Contents
NAME
portreserve - reserve ports to prevent portmap mapping themSYNOPSIS
- portreserve
DESCRIPTION
It is intended that portreserve runs from an initscript of its own, and services wishing to interact with it should use portrelease.
When the portreserve daemon is started, it examines the /etc/portreserve/ directory. Each file not containing lq.rq or lq~rq in its name is considered to be a service configuration file, and must contain a service name (as listed in /etc/services) or a port number. UDP services may be specified by appending "/udp" to the service name, and TCP services by "/tcp". Several services may be specified, one per line.
For example, /etc/portreserve/cups might contain the string lqipprq or, equivalently, lqipp/tcprq and lqipp/udprq on separate lines.
For each service configuration file, a socket is created and bound to the appropriate port. A service wishing to bind to its port must first run portrelease, which instructs portreserve to release the port associated with the service.
Once all the reserved ports have been released, the daemon exits.
FILES
/etc/portreserve/*
- Service configuration files
/var/run/portreserve/socket
- communication socket for portrelease

“Don’t Repeat Yourself”
During the course of a project, or between projects, I have found patterns that repeat themselves. Since I am the true believer of
the DRY principle, I started collecting them, and created a project whenever I see that the benefit
outweighed the cost.
The result are the following projects.
BuildMaster
http://buildmaster.rubyforge.org
The project that can reduce the size of your project release script greatly.
Also the project that can help build a HTML based web site easily, so that you can deploy them to ANY server that supports HTML. This
site is also powered by BuildMaster.
Cotta
A lightweight Java File IO related framework with the principle of Domain Driven and Test Driven.
See Cotta Power for the initial thoughts.
This is also the project that embraced the Behaviour Driven Development.
Selenium-Ruby
A ruby project that wraps the popular Selenium RC project into a gem and provides additional classes for
using Selenium ruby driver to write web testing. This is where I started experimenting the idea of Domain Based Web Testing
jBehave
A testing framework created by Dan North that carries the mission of bringing test-driven development to its full potential:
Behaviour Driven.
I am currently a committer on this project.
Eclipse plugin for IntelliJ keymapping
A little ‘keymap setting’ plugin that helps anyone who has to use both IDE at the same time. To install, configure your Eclipse to update from http://www.shaneduan.com/eclipse
Old Projects
These are the projects that I am not actively work on at the moment.
DbFixture
http://dbfixture.public.thoughtworks.org/
A lightweight testing fixture framework that helps database related testing using HSQLDB.
The idea of DbFixture came out of two projects that we have worked on, both of which involve building our own
data access layer for special reason. After the end of the second project, we put together the requirement and wrote this library.
FitTask
http://fittask.sourceforge.net
An Apache ANT task for Fitnesse to make the integration of Fitnesse to
Continuous Integration easier.
jbuilder-opentools
https://jbuilder-opentools.dev.java.net/
The projects of JBuilder Opentool community during the period when JBuilder is still JBuilder.
XmlFixture
A small library that can be used for XML content assertions.


By default, functionality is hooked to the data-xrayhtml
attribute.
Bolting the data-xrayhtml
attribute on without a value will give you inline code snippets, like so:
Use a heading element with an xraytitle
class to add your own subtitle to the example text.
Also works with a data-title
attribute but that approach is deprecated.
This is a paragraph with text.
Add class="antipattern"
to show a bad example. Also works with subtitles as documented above.
Text
is not a standard HTML element. Do not use this code.Setting “flip” as the value of the data-xrayhtml
attribute will give you this snazzy flip-to-reveal animation (browsers without support for 3D tranforms will simply show/hide the code snippet).
The plugin fires off a create.xrayhtml
event that can be used to attach features like a “copy to clipboard” option (using ZeroClipboard) or syntax highlighting (using Prism.js).
It's also possible to use an iframe for situations where styles (like
media queries) depend on the viewport. Specify the URL for the iframe
with data-xrayhtml-iframe="iframe.html"
on
the data-xrayhtml
element. You can also tell XRay where in
the iframe page to place the included markup
using data-xrayhtml-iframe-target="#replace"
. Otherwise it
will default to replacing the body
HTML with the code XRay
code snippet.


Over a decade ago, Kevin Costner cemented his star status by appearing in two of the best movies ever made about baseball, "Bull Durham" and "Field of Dreams." So "For Love of the Game," which finds Costner returning to the ballpark, arrives with considerable baggage. Will it be a sexy comedy like "Durham" or a world-class tearjerker like "Dreams"? Neither, as it turns out, although the film dabbles somewhat shyly in both genres.
Instead, "Game," which features some of the glossiest photography since Doris Day retired from the screen, is one of those stories in which an aging pro has to decide whether to bow out with some degree of dignity or keep on fighting in the hope of recapturing his glory days. Billy Chapel (Costner) has been a Detroit Tigers pitcher for 19 years and his perpetually aching body is telling him it may be time to hang up his glove for good. Just prior to a game in New York against the Yankees, Billy gets the word the Tigers have been sold and he's about to be traded, prompting plenty of soul-searching on the mound and at least one flashback per inning.
But rather than reflecting on his career, Billy spends the afternoon pondering his l-e-n-g-t-h-y relationship with journalist Jane (Kelly Preston). Though the movie insists theirs is an affair to remember, the evidence presented onscreen is wholly unconvincing. For the past five years it seems these two have been engaged in some games of their own, dropping in on each other with no advance notice so they can feel awful when they get rebuffed, carrying on going-nowhere phone conversations and spending a few fleeting moments in bed together whenever their schedules allow. Oh yeah, and they also apologize -- a lot: "I'm sorry about what I said that day at the condo," "I'm sorry I didn't call," etc.
Last week's episode of HBO's "Sex in the City" offered a perfectly accurate (and unprintable) name for this kind of arrangement; suffice to say it had nothing to do with love. The copious footage devoted to Billy and Jane's encounters might have been easier to sit through is there was any magic between Costner and Preston, but they're acting in two different films.
Like Robert Redford, Costner is a romantic who only truly comes to life opposite a strong female co-star. Pair him with the saucy Susan Sarandon in "Durham," feisty Amy Madigan in "Dreams" or the jittery Rene Russo in "Tin Cup," and he's motivated to work to keep up. With a less secure leading lady such as Olivia Williams in "The Postman" or Jeanne Tripplehorn in "Waterworld," Costner can barely even feign interest.
That's exactly what happens in "Game." Preston, a genuine ball of fire back in the days of "Drugstore Cowboy," has since become a curiously affected actress who always seems to be imitating someone else. In this case, she's doing her best faux Meg Ryan and she's so caught up in determining the proper way to wrinkle her nose she seems to forget who she's sharing the screen with. Consequently, Costner fades out.
Not for a moment do you believe Billy and Jane belong together anywhere outside a hotel suite. Costner actually turns out to have more chemistry with John C. Reilly, playing catcher/confidante Gus. "Game" improves substantially when it concentrates on the friendship between these two veterans who can still remember when baseball was about more than salary caps, TV rights and corporate sponsorship.
Occasionally, writer Dana Stevens' ("City of Angels") dialogue has some of the zing of Ron Shelton's smart-mouthed "Durham" script and there are a few genuinely intriguing passages in which Billy does something called "clearing the mechanism," a mental process that shuts out all the chaos around him and allows him to focus solely on his pitching. These scenes are also the only parts of the movie that seem to have engaged director Sam Raimi's interest; there's very little evidence of his generally audacious style anywhere else. James Sanford

Extensive lab and field work and consultations with fern experts
throughout the US lead us to conclude with considerable confidence:
- The die-off is caused by an unidentified and possibly novel pathogen.
- Climate change and local drought may be contributing factors, but until the
proximal cause of the die-off is determined, the role of climate
can not be known.
- The die-off is unprecedented. We have no evidence that it is
part of the P.munitum life cycle, in which ferns colonize open
ground and rarely reproduce under a closed canopy, with individual
plants typically living for hundreds of years. We tentatively
claim that to a first approximation, and pending rigorous
study of the population structures of healthy sword ferns in
healthy forests, that sword ferns die of "natural causes" very
infrequently.
- The die-off has implications for the forest at Seward Park, and for
other forests in the region.

Things I've learned from
Udacity HTML and CSS lesson 1
HTML is like the meat of a dish. CSS is the seasonings thatgive it flavour; and DOM is sort of like someone's interpritation of the dish.
When designing a webpage a developer should keep in mind that a webpage is presented as a set of boxes in the browser. When designing a webpage, a developer should cut up thier design into boxes to better understand where and how elements will be displayed. Within those boxes are the elements which are displayed. No matter the shape that can be seen on the webpage, it is still within a box in the end. Boxes may have transparent parts as to display circles and other non-box shapes.
The box model is a way to visualize how object will show up in a browser. It contains the margins, paddings, borders and the object itself. It helps when you're trying to position things correctly on the webpage and simply make things look nice.

Me at Habat Habaron in Zichron, with a stunning view of the coastal plain and the sea behind me


III. Competition Environment
1. Track
(1) Track Material
Tracks are made from PCV laminated flooring. The material is same to the 10th, 11th and 12th competition.
(2) Track Dimension, Shape and Spacing
Track width is at least 45cm wide. Preliminary game field is a 5m × 7m rectangle. The final's will be roughly 2 times of that in the Preliminary. The centers of 2 neighboring tracks is at least 60cm apart. The entire track contains straight, curved, cross roads and et cetera. The radii of curved roads are at least 50cm.
(3) Tracking Guides
For different categories, there will be track guides, which includes the following 3:
-
Track Edge Guide
The track edges will have black edge strips for track guidance (strips within the 45cm boundary of the track width). The edge strips have width 25±5mm.
-
Median Electromagnetic Guide
The track will have embedded a central electromagnetic wire. The line is a magnet wire that runs along the center of the track, diameter 0.1~1.0mm, with 20kH, 100mA AC current. Frequency range being 20k±1kHz, current range 100±20mA.
According to information provided by the 20kHz AC wire used in the competition, it is recommended to use the following steps to measure the current of the track. If the current output shape of the wire used by the competing team is similar to a square wave, then the AC mode on the multi-meter is able to tell the current value of the current output.
The recess in the track to fixate the magnet wire can be made with some tools. A dual-blade hobby knife with a blade gap of 1.5mm can draw out material along the median line of the track. After removing the PVC strip, an inset with depth 1mm, width 1.5mm would have been made for laying the magnet wire.
-
Beacon Guide
There will be 5 to 10 beacons on the game field on the blue PVC canvas. The car shall move according to the guide of the beacons. Around the beacons are red, and IR LED arrays and on top hold speakers. The LEDs and speakers are activated through the competition system. Regarding the specifications and production methods of the beacons, please refer to The 13th Intelligent Car Racing Competition Beacon Competition System Manual.
During the Dual-Car Duel competition, the car can recognize the emitted red light or IR of the beacon via sensors or cameras or such to locate its position. It is also possible to locate the sound source via a microphone array. Since the beacon utilizes both light and sound guide, the accuracy of identification of that by the cars is increased, and the impact of environmental light rays is decreased.
(4) Starting Line Indication
The competition requires cars to automatically stop in the stopping zone after competition completion. Except for the Creative category, all other categories require cars to stop in the 3m track region behind the starting line. When stopping, all wheels of the car should remain on the track.
The indication of the starting line include the 2 following schemes:
Zebra strips starting line: The starting location for activation of the timer has a line of black zebra strips of 10cm of width. The material for the zebra strips uses the same as that for the black edge strips.
For the Electromagnetic categories, at the center of the track lies permanent magnets. The magnet parameters: diameter 7.5~15mm, height 1-3mm, surface magnetic field strength 3000-5000Gs.
The distribution of the permanent magnets near the starting position are aligned in a way such that they are mirrors along the center with the center magnet directly on the median line and a magnet on each side spaced 4cm from centers of the magnets. The 3 magnets forms a line perpendicular to the travel direction.
For the Beacon Duel competition, the starting zone is at a corner of the game field, forming a square with each side 50cm wide. At the end of the competition, the cars are not required to stay at some stopping zone.
(5) Track Edge Judging
Except the Beacon Duel category, all other categories require cars to stay on the track full time during the run.
On the edge of the game tracks may lie 2 layers of high-density black sponge strips, forming a shoulder for the track, as the border of the track. It is also possible that there may not be high-density black sponge strips.
The sponge strips have width 2.5cm, the double layer has height 1cm. For every other 25cm of track edge, there will be a sponge strip which has length of 25cm, forming a dashed line. Edges where there is no sponge strips still have the black edge strips.
For tracks that has shoulders, manual judging will be used to decide whether or not to give penalty to cars that run off track. The penalties and standards are the same as previous competitions. For tracks that do not have shoulders, the judging system will be used, and random places will be chosen with sensor coils installed to automatically give penalties. Details of the penalty standards will be released as Penalties Specification Documentation.
In the 13th competition, some regional competitions will utilize automatic judging system to replace manual judging for cars running off track. By then, the competitions will not install shoulders for track edges. Details of the standards will be release in The 13th Intelligent Car Racing Competition Automatics Judging System and Game Flow.
(6) Track Elements
The competition track is a closed-loop track, with the following track elements.
| Track Elements | Details |
|---|---|
| Straight Road | The basic track. |
| Curved Road | The track contains multiple curved road sections. These curved sections can form a roundabout, rounded turn, S-shaped tracks, et cetera. The radii of the curved tracks are at least 50cm. |
| Cross Road | Cars passing the cross road sections are required to pass straight. Turning left or right are not permitted. |
| Track Obstacles | The track obstacles are symmetrical triangular wedges, with length, width, height be 30cm, 10cm and 5cm correspondingly. The side of the wedge closer to the center of the track is spaced 5cm to the central line. Electromagnetic categories do not have track obstacles. These categories include: Electromagnetic, Power-Saving, Electromagnetic Dual-Car Chasing |
| Ramp | The ramp slopes do not exceed 20°. Ramps do not have to be symmetrical. Transitional sections of the ramp are longer than 10cm. There is no limits of the length and height of the ramps. Under normal circumstances, the total length of the ramps are around 1.5m. The guide wire of Electromagnetic categories are laid along the surface of ramps. |
| Ring Road | Cars entering ring roads should run along the ring once then continue straight out. The ring roads has radii not less than 50cm. Electromagnetic guide wires are also run along the ring once. |
| Bumpy Surface | Straight tracks may contain a section of bumpy road section no longer than 1m. At most 2 bumpy sections will exist on one track. The Bumps are produced by cutting single layered KT boards. The horizontal length of a bump is the same width of the track. Its width is 10cm, height smaller than 0.5cm, spacing 10cm apart from side to side. The top rectangle of the bump is tapered such that the slop of the tapered sides forms 45° from the ground. |
The above track elements are used as the following table states:
| Track Elements | Regional Prelim. | Regional Final | Regional Additional Match | National Final |
|---|---|---|---|---|
| Straight Road | Y | Y | Y | Y |
| Curved Road | Y | Y | Y | Y |
| Cross Road | Y | Y | Y | Y |
| Track Obstacle | Y | Y | N | Y |
| Ramp | N | Y | N | Y |
| Ring Road | Y | Y | N | Y |
| Bumpy Road | Y | Y | N | Y |
2. Environment
(1) Game Field
- The game field should have a smooth flooring. If the flooring is smooth cement, Terrazzo or marble, then the tracks will be directly installed on top. Whereas if the flooring is a carpet material, then there will first be a layer of KT board above the flooring, then have the tracks installed above that.
- Color of the flooring: The color of the flooring should have certain contrast with the white track. The color is determined according to the flooring used on-site. Under normal circumstances, blue canvas will be used to set the background color. Details of the actual background color used at the competition will be released one month before the official competition.
(2) Environmental Lighting
The competition venue is normally indoors. During the competition, there must not be direct sunlight nor intensive incandescent lighting. For the 2 Electromagnetic categories, because the impact of environmental lighting to the competition is less, therefore, there will not be limitations stated above, and the venue may be at a venue outside with no direct sunlight.
(3) Game Field Border Walls
There will be walls surrounding the game field. The walls are at least 50cm away from the track. The height of the walls are at least 30cm high. The material of the wall may be rectangular foam blocks, or banner cloth.
3. Judging System
The timing judging system used in the competition will automatically record car running time and judge whether the cars run off track automatically.
(1) Car Timing Magnetic Label
The magnetic field sensing recording method used by the competition records the instant of when the cars run across the starting line, or detecting whether or not the car is running within 22.5cm around the beacons. Sensor coils are places under the track and around the beacons, and the interference to the running car is small. In the mean time, the car cannot easily crash into the timing system.
For the car to trigger the timing system, it is required to install a piece of permanent magnet as label under the car. The permanent magnet should be at most 2cm from the ground. Because the size of the magnetic label is small, it increases the accuracy in measuring the location of the car.
Timing magnetic labels can be permanently adhered to the bottom plate of the car, or temporarily affixed on the bottom plate or on the motors before competition. The exact placement of the magnetic label is not important, because time is measured by recording the time interval every time the magnetic label passes the sensor coils.
Special notice for the Beacon Duel category, only when the magnetic label enters the sensor coil ring around the beacon, does the timing system gets triggered to light up the next beacon.
(2) Timing System
The competition timing system and the beacon control system are all installed by the competition organizing committee.
Contestants may design a simplified competition system to help debug their cars during regular practices. They can also refer to The 13th Intelligent Car Racing Competition System Manual in order to design and construct the system.
