About The Event
Robobridge is a robotic event in which the robot has to carry particular objects using the arm mechanism
to the given destination.
Objective
To design a wired/wireless manually controlled robot having the ability to lift the objects from one
place to another using arm mechanism. This task should be performed on an arena which will be designed
like bridge.
Bot Specifications
- Bot dimension should be such that it can be enclose inside a box of dimensions 30cm*30cm*30cm.
- The weight of the bot should not exceed 3 kg.
- The bot can be wired or wireless manually controlled.
- Battery voltage should not be more than 12 volts.
- The bot must have on-board power supply.
- The bot should be controlled using a single wired remote in case of wired and by a single device or
wireless remote in case of wireless bot.
Team Specification
- The maximum number of members in a team should not exceed 4.
- Student from different colleges can be a part of single team.
- An individual cannot be a part of more than one team.
Competition Rules
The event will be conducted in two phases.
Transporter
- Transporter is a qualifier round in which the bot has to travel on a plane surfaced bridge with the
object (size and shape may vary) in the arm and transport it to another location.
- The shipment of the objects will carry a constant point and there will be negative markings in
different situations.
- The bot should not deal any damage to the arena. If there is any kind of damage to the arena than
the negative marks will be given to the team.
Ascender
- Ascender is the final round of robobridge in which the bot has to climb the bridge of different
elevations with the object in the arm.
- There will be specified location for different colored or shaped objects in which it has to be
placed by the robot.
- Touching the bot in the middle of the task will result in penalty.
NOTE
- In case of any dispute or ambiguity, event coordinator’s decision will be final.
- The organizers reserve the rights to change any or all of the above rules and scoring pattern.

In the end of June, UK voters decided the fate of the country in a referendum over Britain’s continuing membership of the European Union (EU). Under such circumstance, the economy of UK could be affected. The project mainly concerns about whether household consumption has been effected by Brexit.
Following the EU referendum, the value of sterling fell sharply against the dollar at the end of June and into July. In July 2016,the sterling Exchange Rate Index (ERI) was 15% lower compared with July 2015 and 6.6% lower compared with the average level in June 2016. In August 2016 and September 2016, the exchange rate showed some signs of increasing, however the value of sterling fell continued decreasing after September 2016. Figure 1 shows British Pound (GBP) to US Dollar (USD) exchange rate from 01/01/2014 to 31/10/2016. This indicates that the pound has fallen against the dollar, following the UK's vote to leave the European Union. The falling pound leads to the import price increasing.
This figure shows the index of import price from May 2014 to October 2016 compared with that of in 2013 and the standard in 2013 is 100. Then index of import price shows a slight fluctuate before referendum and it average at 90.7 in the fist 6 month of 2016.Then it rise up considerably after referendum to 95.2 in July 2016. The data is trend to stable in the next 3 months from July to September and then experience a dramatic growth to 97. 8. Compared with the exchange rate between the pound to dollar, we can find that the trend form this two graph show a crosscurrent. In the fist month of referendum, the Sterling exchange rate shapely decrease and the import price shapely increase. In the July, August and September, the Sterling exchange rate tends to be stable and the import price shows the same tendency. Then the October saw a dramatic drop while the import price keep an upward tendency. Thus the referendum influences the import price through the Sterling exchange rate. After referendum, the Sterling exchange rate going down and the import price show a rise trend.
Consumer price inflation is the rate at which the prices of goods and services bought by households fall or rise. Consumer price inflation is estimated by using price indices. The easy way to understand this is to assume that a very large shopping basket contains all the goods and services bought by households,and movements in price index represent the changing cost of this basket. The price index can be used to measure inflation in a number of ways. The most common way is to find how the index has changed over a year. To calculate price index, comparing the price index for the latest month with the same month a year ago. This is known as the 12-month inflation rate. The CPI is a measure of consumer price inflation created to international standards. Figure shows UK's CPI 12-month inflation rate from January 2014 to October 2016. It shows that consumer price inflation suddenly rose in September. The annual rate of CPI inflation was 1 per cent, up from 0.6 per cent in July
This figure shows the price of household consumption and the index of the amount of expenditure relative to the volume in 2013. Current price: It represents the value of consumption price in a quarter. Chained volume measure: The estimation of the volume of goods and services that household consumed. The value of price and the amount of consumer goods keep an upward tendency science since the first quarter in 2014. However it show a more obvious growth after Brexit vote. The current price quarter 3 (2016) increased by 1.3% compared with the value in quarter 2(2016) and quarter 2 compared with quarter 1 in 2016, experiencing 0.6% growth. Looking the index of the chained volume measure, they rose up by 0.7% and 1.0% respectively when the data in quarter 3 compared with quarter 2 and quarter 2 compared with quarter 2. Thus the household consumption increasing after referendum.

| Y / N indicates whether this message is part of the spec for this direction (C2S/S2C) and mode (HTTP/Sock). | ||||||
| Message type | C2S HTTP |
C2S Sock |
S2C HTTP |
S2C Sock |
Purpose | |
| HelloFrame(helloData) | Y | Y | N | N | Used to authenticate each transport that connects to the Minerva server. C2S only because HelloFrame is used by the client to identify itself to the server, and set critical transport parameters. | |
| StreamCreatedFrame() | N | N | Y | Y | Sent to indicate that a ServerStream has been successfully created. This is the first frame sent over *every* sucessfully-authenticated transport with `requestNewStream`, so it may be sent over more than one in transport. This allows the client to know that it can now send smaller HelloFrames without `requestNewStream` and `credentialsData`. | |
| CommentFrame(comment) | N | N | Y | Y | CommentFrame is used for HTTP anti-script-inclusion preamble, padding, and heartbeats. Padding is only needed to work around browser problems with content sniffing (in IE, Safari, Chrome, maybe Opera?), and maybe annoying proxies. | |
| SeqNumFrame(nextSeqNum) | Y | Y | Y | Y | "The next string I write to the transport will have this seqNum" | |
| StringFrame(string) | Y | Y | Y | Y | Both peers send strings - every other frame supports this basic function. `string` is restricted to the base "restricted string" codepoints. | |
| ResetFrame( reasonString, applicationLevel?) |
Y | Y | Y | Y | Either peer can reset if they've given up on this stream. `reasonString` is restricted to the base "restricted string" codepoints. | |
| SackFrame(sack) | Y | Y | Y | Y | Both parties need to sack often to free memory in their peer's send queue | |
| StreamStatusFrame( lastSackSeenByServer) |
N | N | Y | Y | Used to tell the client the `lastSackSeenByServer` before server closes the transport.  S2C only. Client also sends similar information to server, but it does so with `lastSackSeenByClient` in the HelloFrame. | |
| YouCloseItFrame() | N | N | Y | Y | In S2C context: This is useful when server wants client to do active close on the TCP socket for this transport (usually, to avoid having TIME_WAIT sockets). If server sends YouCloseItFrame over an HTTP transport, client must try to close the HTTP connection. (usually with xhrObject.abort() or removing an iframe) | |
| TransportKillFrame( "stream_attach_failure") |
N | N | Y | Y | This error is a possible response to HelloFrame. It means transport authentication failed, or streamId does not exist. | |
| TransportKillFrame( "acked_unsent_strings") |
N | N | Y | Y | This error is a response to client sending a SackFrame that SACKed strings that server never sent. Only the server sends acked_unsent_strings. If the client thinks server sent a bad SACK, it should send ResetFrame. | |
| TransportKillFrame( "frame_corruption") |
N | N | Y | Y | This error is a response to client sending corrupt frame octets or an overlong frame. Only server sends frame_corruption. If client received corrupt frames, it should make a new transport. | |
| TransportKillFrame( "invalid_frame_type_or_arguments") |
N | N | Y | Y | This error is a response to client sending any unknown frame, or frame with invalid arguments. Only server sends invalid_frame_type_or_arguments. Only server sends invalid_frame_type_or_arguments. If client gets an unknown frame type or bad arguments, it should make a new transport. | |
| TransportKillFrame( "rwin_overflow") |
N | N | Y | Y | This error is a response to client that has caused the server's receive window to overflow by sending strings that cannot be delivered. Later, client can connect a new transport and send deliverable strings. Only server sends overflowing_rwin. If client's receive window is overflowing, it should make a new transport and write a SackFrame. | |
| HelloFrame arguments are
documented in frames.py and frames.js Presence of succeedsTransport option means "give me strings, server". If succeedsTransport != null, temporarily assume that all strings written to #<succeedsTransport> were SACKed. Idea: perhaps ackMode: 0 - require Minerva-level SACKs, 1 - use my TCP acks, 2 - assume everything written is received |
||||||
| Idea: maybe distinct 'shutdown' and 'reset'? | ||||||
| Idea: advise_connect_bulk_transport: S2C-only message: Server indicates that client should try to establish an S2C transport more suitable for bulk transport. TODO: define this more | ||||||
| Why does server send TransportKillFrames, but client does not? Because the server doesn't really care about the client's problems with decoding frames. Server is still interested in this "problems" data, so it could be sent in a batch later. |

Since money hasn't materialized for another year of full-time work on this course, I'm now looking for a job. My CV is up to date, and my interview shoes are polished, so if you know of anything meaningful and interesting in downtown Toronto [1], please give us a shout. I'd obviously prefer something related to scientific computing, Python, and/or education, but wherever I wind up, Software Carpentry will keep going. As always, if you'd like to help with that, please get in touch.
[1] After all the work we've done on this house in the last two and a half years, if I suggest relocating to my wife, I'll be doing it as a single man :-)


I was tasked with solving the digital health business’ and their users’ needs. During this time:
Since I was new to the company and our audience, I decided to look into our company’s existing research and conduct some of my own. I discovered BlueJay was still looking for their target audience, while talking with the business. We set up a meeting and discussed their business needs, their target audiences, as well as an overview of the United States’ healthcare system’s situation regarding both parties:
After discussing these topics, we narrowed down our target audience: Private outpatient physical therapist clinics and practitioners were their primary target audience.
I immediately scheduled interviews with several of our beta testers and with several private physical therapy clinics who expressed interest in a mobile physical therapy tool. From these, I interviewed 10 physical therapists and clinic owners.
Using the data I gathered and synthesized from our interviews, I designed our main persona and several proto personas:
During this stage we decided to focus solely on the physical therapist's side because physical therapists needed to be on the platform first so they can schedule in their patients, as well as vice-versa.
I discussed with my team and decided that my priorities were to redesign and to create new pages for the existing website, conduct usability studies on the existing app, and design screens for the payment flow of the app.
We tested primary user's most vital flows: adding a patient list, prescribing treatment plans to patients, and conducting virtual visit.
For these pages, I added the HIPPA Compliance page, updated every single page styles, cleaned up the code to fit proper semantics, and made the pages responsive so that potential users would be able to acccess the website on their phone after learning about the product at a conference.
In the end, after evaluating all of the research including a satisfaction survey, results showed that users liked the idea but wanted a more streamlined approach. So the company set to redesigning the product.
We also made redesigning the website a priority, since the Combined Sections Meeting by the American Physical Therapy Association was coming up in the next month, by taking my existing designs and redesigning the website using Webflow.
Before my contract ended, I created a basic framework on Webflow; this lead to the current website's design.
Given the time and resources, we couldn’t pull enough resources to revamp the existing flow. Instead we pinpointed the existing issues and tried to solve them, while keeping in mind we would need to do an overhaul of the existing app in the future.
I learned that working with the engineers and keeping them up to date helps everyone. They would give me great feedback which could change the designs based on viability and easy of implementation.
There were times I needed to take a step back in my work-life balance. I'm glad that I noticed whenever I would become too tunnel-visioned in a design and needed to take a step back because those were the moments which led to the most crucial decisions.

Exercise 2: Add and use an existing Effect (XAM330)
In this exercise, you'll use a provided custom font effect and apply it to a Xamarin.Forms label.
To complete the exercise, you will need Visual Studio for Windows or macOS with the Xamarin development tools installed. You will also need either an emulator/simulator or a device to run the exercise on. Please see the setup page if you need help installing the Xamarin development environment.
Open the starter solution
Open the starter solution from the Exercise 2 > Start folder in your copy of the cloned or downloaded course materials in either Visual Studio on Windows or Visual Studio for Mac.
Add the Effect and font
The Assets folder contains a platform-specific custom font effect for each platform. This effect is designed to be applied to a Xamarin.Forms Label.
- Add the appropriate CustomFontEffect source file to each platform-specific project.
-
Add the provided Pacifico.ttf font to each head project:
- iOS: Add it to the Resources folder. The Build Action should be BundleResource.
- Android: Add it to the Assets folder. The Build Action should be AndroidAsset.
- Windows: Add it to the Assets folder. The Build Action should be Content.
-
For iOS only: update the Info.plist to include the font.
- In Visual Studio for Mac, double-click on Info.plist and change the view to Source via the tabs at the bottom. Add a new entry by right-clicking and selecting New key. Change the Property to Fonts provided by application. Under the new entry add a string with the value Pacifico.ttf.
-
In Visual Studio on Windows, you'll need to edit the Info.plist file manually: right-click and select Open with..., from the provided options select XML (Text) Editor and add the following xml:
<key>UIAppFonts</key> <array> <string>Pacifico.ttf</string> </array>
Resolve the Effect
- Open MainPage.xaml.cs in the ControlExplorer PCL project.
- Create an
Effect
field named fontEffect. -
In the constructor, use the ID of the custom font effect ("Xamarin.CustomFontEffect") to resolve the
Effect
. Assign the resolvedEffect
to the fontEffect field.public partial class MainPage : ContentPage { Effect fontEffect; public MainPage() { InitializeComponent(); fontEffect = Effect.Resolve("Xamarin.CustomFontEffect"); } }
Apply the Effect
- Examine the code in MainPage.xaml, notice there is a
Label
named labelWelcome. - Return to the constructor in MainPage.xaml.cs.
- Add fontEffect to labelWelcome using the
Add
method on labelWelcome'sEffects
property. -
Run the application on any platform; you should see the custom font on the label showing the text "Welcome to Effects!".
public MainPage() { ... fontEffect = Effect.Resolve("Xamarin.CustomFontEffect"); labelWelcome.Effects.Add(fontEffect); }
Toggle the effect on/off
Next you'll use the switch to turn the effect on and off.
- Go to the
OnSwitchToggled
method in MainPage.xaml.cs. -
Check switchEffects'
IsToggled
property and add/remove the effect depending on the switch's state. A possible solution is shown below.private void OnSwitchToggled(object sender, ToggledEventArgs e) { labelWelcome.Effects.Remove(fontEffect); if(switchEffects.IsToggled) labelWelcome.Effects.Add(fontEffect); }
Exercise summary
In this exercise you added a provided Effect that uses platform-specific APIs to apply a custom font to a Xamarin.Forms label.
You can view the completed solution in the Exercise 2 > Completed folder of your copy of the cloned or downloaded course materials.


keyword: affect
Drug use can have a wide range of short- and long-term, direct and indirect effects. These effects often depend on the specific drug or drugs used, how they are taken, how much is taken, the person's health, and other factors. Short-term effects can range from changes in appetite, wakefulness, heart rate, blood pressure, and/or mood to heart attack, stroke, psychosis, overdose, and even death. These health effects may occur after just one use. Longer-term effects can include heart or lung disease, cancer, mental illness, HIV/AIDS, hepatitis, and others. Long-term drug use can also lead to addiction.  Not everyone who uses drugs will become addicted, but for some, drug use can change how certain brain circuits work. These brain changes interfere with how people experience normal pleasures in life such as food and sex, their ability to control their stress level, their decision-making, their ability to learn and remember, etc. These changes make it much more difficult for someone to stop taking the drug even when it’s having negative effects on their life and they want to quit. Drug use can also have indirect effects on both the people who are taking drugs and on those around them. This can include affecting a person’s nutrition; sleep; decision-making and impulsivity; and risk for trauma, violence, injury, and communicable diseases. Drug use can also affect babies born to women who use drugs while pregnant. Broader negative outcomes may be seen in education level, employment, housing, relationships, and criminal justice involvement.


Continuous convex piecewise linear (ccpl) resp. quadratic (ccpq) functions can be implemented with sorted breakpoints and slopes. This includes functions that are ccpl (resp. ccpq) on a convex set (i.e. an interval or a point) and infinite out of the domain. These functions can be very useful for a large class of optimisation problems. Efficient manipulation (such as log(N) insertion) of such data structure is obtained with map standard template library of C++ (that hides balanced trees). This package is a wrapper on such a class based on Rcpp modules.

Clock recovery is the process of extracting timing information from a serial data stream to allow receiving circuit to decode the transmitted symols. Clock recovery from the data stream is expedited by modifying the transmitted data where in serial communication channel doesn't transmit the clock signal along with the data stream, the clock must be regenerated at the receiver using the timing information from the data stream
Demodulation of frequency modulation (FM): If PLL is locked to a FM signal, the VCO tracks the instantaneous frequency of the input signal. The filtered error voltage which controls the VCO and maintains lock with the input signal is demodulated FM output. The VCO transfer characteristics determine the linearity of the demodulated out. Since the VCO used in an integrated-circuit PLL is highly linear, it is possible to realize highly linear FM demodulators.
$$X_{FM}(t)={A_ccos[\omega_ct+K_{VCO}\int^t_{-\infty}{x_{BB}(\tau)d\tau}]}$$Delay locked loop is used to synchronize signal that is spreaded using Direct-Sequence Scheme where we also replaces the internal Voltag-Controlled-Oscillator, by a delay ine. and we use DLL to change the phase of clock signal and also to use it in clock recovery
A 2/3 divider cell comprises two functional blocksThe prescaler logic block divides \(F_{in}\), upon control by the end-of-cycle logic, the frequency of the input signal either by 2 or by 3, and outputs the divided clock signal to the next cell in the chain The end-of-cycle logic controls the momentaneous division ratio of the cell. The division ratio depends on the state of \(mod_{in}\) and p signals,The\(mod_{in}\) signal becomes active once in a division cycle. At that moment, the state of the p input is checked, and if p=1 the end-of-cycle logic forces the prescaler to swallow one extra period of the input signal. In other words, the cell divides by 3. If p=0, the cell stays in division by 2 mode. Regardless of the state of the p input, the end-of-cycle logic reclocks the \(mod_{in}\) signal, and outputs it to the preceding cell in the chain
Simulation didnot work well in cadence so I made it in simulink with the following block diagram
The Dual Modulus Prescaler subsystem block consists of a program counter, a swallow counter and a prescaler.
When the block first receives an input signal, the pulse swallow function is activated. The prescaler divides the input signal
frequency by (N+1), where N is defined by the Prescaler divider value (N) parameter.
Both the program and swallow counters start counting. The swallow counter resets after counting to S pulses,
or (N+1)S cycles, where S is defined by the Swallow counter value (S) parameter.
Then, the pulse swallow function is deactivated, and the prescaler divides the input frequency by N.
Since the program counter has already sensed S pulses, it requires (P-S) more pulses, or (P-S)N cycles to reach overflow,
where P is defined by the Program counter value (P) parameter. The cycle repeats after both counters are reset.
$${{f_{in}}\over{f_{out}}}=(N+1)S+N(P-S)=NP+S={2 \over 3}$$
all-digital PLL has all digital elements, including the phase detector, loop filter and oscillator; they don't have the supply limitations of analog PLL ands and advanced all digital phase locked loops are fully synthesizable and customizable. each elements we were designing in analog pll we connect it to ADC and DAC inorder to control it digitally
The purpose of this part is to simulate the (linear) PLL circuit in Simulink environment. As discussed in the lecture, the PLL is widely employed in communication and electronic application as it has many functions. In this project, you are going to simulate the PLL as a circuit that performs synchronization between two signals that have different phase and frequency.
The type of PLL shown in fig(2) is linear model for PLL where, The Model in Figure 2 has three main components:

Gauge Fields
One notable feature of GPUE is its ability to use gauge fields to create rotational effects in BEC simulations. Gauge fields are somewhat tricky to understand and this guide is not meant to provide a full physical understanding of what the fields are or how they work. If you with to learn more about the physical interpretation of these fields, this review by Jean Dalibard is relatively in-depth.
This section will highlight how gauge fields are implemented in GPUE and how to use them on your own as a user of the codebase. If you wish to provide a new default field in GPUE, itself, please go to the developer guide for this later in the documentation and provide an appropriate PR to GPUE on GitHub
Introduction to gauge fields
For the purposes of the GPUE simulations, we will be solving the non-linear Schrödinger equation:
$$ \frac{\partial \Psi(\mathbf{r},t)}{\partial t} = \left( \frac{(p-m\mathbf{A})^2}{2m} + V_0 + g|\Psi(\mathbf{r},t)|^2 \right)\Psi(\mathbf{r},t), $$
where $\Psi(\mathbf{r},t)$ is a complex-valued wavefunction, $r$ is a real-space grid, $p$ is a momentum-space grid, $m$ is the mass of the atomic system, $V_0$ is a real-valued trapping potential, $g$ is a coupling constant, and $A$ is a real-valued gauge field. As mentioned, the gauge field is hard to physically interpret; however, it can be more easily understood through the artificial magnetic field, $B = \nabla \times A$. Here, it appears that rotation occurs around the magnetic field lines, so vortices in a BEC will follow the direction of the magnetic field at any moment in time.
Gauge fields are implemented in GPUE by splitting the operator up in position and momentum space. Because $p$ is completely in momentum space, while $A$ is in real space, the $\frac{(p-mA)^2}{2m}$ term will have three different types of values after expanding:
$$ \frac{(p-mA)^2}{2m} = \frac{p^2 + (mA)^2 + 2mpA}{2m} $$
Here, $\frac{p^2}{2m}$ will be in momentum-space, $\frac{mA^2}{2}$ will be completely in position-space, and $pA$ will be in momentum-space for one dimension and position space for all other dimensions. For example, one possible gauge field can be created with the angular momentum operator as $xp_y - yp_x$.
Because of this, we need to perform a 1 dimensional FFT on our wavefunction in order to apply our gauge fields to the system. This means that when we run the simulation with gauge fields, we need to perform an additional FFT every timestep for each dimension of our system. In addition, we need to read in a field for each dimension. For example, with $A = xp_y - yp_x$, we will use the following field:
$$ \begin{align} A_x &= -y \newline A_y &= x \newline A_z &= 0 \end{align} $$
To apply this field, we will need to FFT our wavefunction in first the x-direction, then multiply by $A_x$, iFFT back and do the same for $A_y$ and $A_z$. This is a costly process, which is why you should only use gauge fields if you need them.
As mentioned, this documentation does not intend to provide a full in-depth description of gauge fields and artificial magnetic fields. It instead attepts to provide the basics for users that may need more information about what gauge fields are and how they influence the simulation. Basically, if you want to do vortex simulations, you will need gauge fields.
Using gauge fields in GPUE
GPUE comes packaged with a few in-built gauge fields:
- Rotation: This is used with the
./gpue -A rotation
flag. Here, we apply the rotational operation to the wavefunction as $\Omega(xp_y - yp_x)$, where $\Omega$ is some rotation frequency. If a rotation above some critical rotation frequency is used, vortices will appear in the BEC, eventually creating a triangular vortex lattice. - Constant: This is used with the
./gpue -A constant
flag. Here, we simply read in $A_x = A_y = A_z = 0$. This is useful for debugging in certain cases - Test: This is used with the
./gpue -A test
flag. Here, we apply a constant field in $A_y$ and $A_z$ and provide a sinusoudal field in $A_x$. This is another testing field that does not use standard rotation. - File: This is used with the
./gpue -A file
flag. Here, we read the fields in from file. This will naturally look for the fields indata/Axgauge
,data/Aygauge
, anddata/Azgauge
. If these files are not found, it will ask for an appropriate filename. If the file length does not match the dimensions of the system, it will also ask for a new file.
To run the simulation with gauge fields, the -l
flag is necessary and will turn on the part of the simulation with the additional FFT’s for applying the necessary gauge field.
No gauge field will be applied without the -l
flag!
Gauge fields can also be used with the dynamic fields to be covered in the next section!

Below are some assumptions that we made while using decision tree:
As you can see from the above image that Decision Tree works on the Sum of Product form which is also known as Disjunctive Normal Form. In the above image, we are predicting the use of computer in the daily life of the people.
In Decision Tree the major challenge is to identification of the attribute for the root node in each level. This process is known as attribute selection. We have two popular attribute selection measures:
Example:
Lets consider the dataset in the image below and draw a decision tree using gini index.
| Index | A | B | C | D | E |
|---|---|---|---|---|---|
| 1 | 4.8 | 3.4 | 1.9 | 0.2 | positive |
| 2 | 5 | 3 | 1.6 | 1.2 | positive |
| 3 | 5 | 3.4 | 1.6 | 0.2 | positive |
| 4 | 5.2 | 3.5 | 1.5 | 0.2 | positive |
| 5 | 5.2 | 3.4 | 1.4 | 0.2 | positive |
| 6 | 4.7 | 3.2 | 1.6 | 0.2 | positive |
| 7 | 4.8 | 3.1 | 1.6 | 0.2 | positive |
| 8 | 5.4 | 3.4 | 1.5 | 0.4 | positive |
| 9 | 7 | 3.2 | 4.7 | 1.4 | negative |
| 10 | 6.4 | 3.2 | 4.7 | 1.5 | negative |
| 11 | 6.9 | 3.1 | 4.9 | 1.5 | negative |
| 12 | 5.5 | 2.3 | 4 | 1.3 | negative |
| 13 | 6.5 | 2.8 | 4.6 | 1.5 | negative |
| 14 | 5.7 | 2.8 | 4.5 | 1.3 | negative |
| 15 | 6.3 | 3.3 | 4.7 | 1.6 | negative |
| 16 | 4.9 | 2.4 | 3.3 | 1 | negative |
In the dataset above there are 5 attributes from which attribute E is the predicting feature which contains 2(Positive & Negative) classes. We have an equal proportion for both the classes.
In Gini Index, we have to choose some random values to categorize each attribute. These values for this dataset are:
A B C D >= 5 >= 3.0 >= 4.2 >= 1.4 < 5 < 3.0 < 4.2 < 1.4
Calculating Gini Index for Var A:
Value >= 5: 12
Attribute A >= 5 & class = positive:
Attribute A >= 5 & class = negative:
Gini(5, 7) = 1 –
Value < 5: 4
Attribute A < 5 & class = positive:
Attribute A < 5 & class = negative:
Gini(3, 1) = 1 –
By adding weight and sum each of the gini indices:
Calculating Gini Index for Var B:
Value >= 3: 12
Attribute B >= 3 & class = positive:
Attribute B >= 5 & class = negative:
Gini(5, 7) = 1 –
Value < 3: 4
Attribute A < 3 & class = positive:
Attribute A < 3 & class = negative:
Gini(3, 1) = 1 –
By adding weight and sum each of the gini indices:
Using the same approach we can calculate the Gini index for C and D attributes.
Positive Negative For A|>= 5.0 5 7 |<5 3 1 Ginin Index of A = 0.45825
Positive Negative For B|>= 3.0 8 4 |< 3.0 0 4 Gini Index of B= 0.3345
Positive Negative For C|>= 4.2 0 6 |< 4.2 8 2 Gini Index of C= 0.2
Positive Negative For D|>= 1.4 0 5 |< 1.4 8 3 Gini Index of D= 0.273
The most notable types of decision tree algorithms are:-
1. Iterative Dichotomiser 3 (ID3): This algorithm uses Information Gain to decide which attribute is to be used classify the current subset of the data. For each level of the tree, information gain is calculated for the remaining data recursively.
2. C4.5: This algorithm is the successor of the ID3 algorithm. This algorithm uses either Information gain or Gain ratio to decide upon the classifying attribute. It is a direct improvement from the ID3 algorithm as it can handle both continuous and missing attribute values.
3. Classification and Regression Tree(CART): It is a dynamic learning algorithm which can produce a regression tree as well as a classification tree depending upon the dependent variable.

IE10 includes support for HTML5 Forms. HTML5 Forms offers two major advantages over previous versions: new input types and built in validation. The form below is an example cake order form that utilizes validation and new input types.
Here are some interesting scenarios you may wish to try:
After submitting try filling in different fields and see what happens.
<input type="email"/>
<input type="url"/>
<input type="number"/>
The value entered must be a valid floating point number. If you enter a value which is not a number, it will be cleared from the input box after focus moves away.
<input type="tel"/>
Allows browsers to optimize for telephone number input but doesn't constrain the value.
<input type="search"/>
Works exactly the same as text boxes.
<input type="text" required/> <input type="checkbox" required/> <textarea required/>
Required elements can't be submitted without a value.
<input type="text" placeholder="John Doe">
Placeholder text is visible until focus is placed in the element. It can be styled with pseudoclass :-ms-input-placeholder.
<input type="text" pattern="abcd" title="enter 'abcd'"/>
The pattern attribute is a regular expression that the value must match. In the example above entering 'abcd' works but any other value will be rejected.
The autofocus attribute lets web developers specify where they want focus to go after the page loads. For example, if you go to bing.com, you want focus to go to the search box on the page so that you can just immediately start typing.
<input type="number" min="0" max="10" step="2"/> <input type="number" min="0" max="10" step="0.5"/>
Defines the minimum, maximum and step values for number input elements. The step attribute defines the jump between values that are allowed. For example, if min=0 and step=1 then 0,1,2,3... will be allowed. If min=1.1 and step=1, then 1.1, 2.1, 3.1, ... will be allowed.
<input type="file" multiple/> <input type="email" multiple/>
Lets the web developer allow multiple files or email addresses in a single input box.
<input type="text" list="messages"/> <datalist id="messages"/> <option>Happy Birthday</option> ...</datalist>
Provides suggestions similar to autocomplete.
input:valid {border:solid lime;} input:invalid {border:solid red;}
input:required:invalid {border:yellow solid;}
<input type="number" min="0" max="100" name="num" onchange="checkValue(this)"/> function checkValue(elt) { if (elt.validity.rangeOverflow) { elt.setCustomValidity("Please call the bakery directly for orders over 100 people"); else { elt.setCustomValidity(""); } }
<input type="email" onchange="checkValue2(this, document.getElementById('errorMessage'))" oninvalid="return false"/> You must enter a valid email address! <input type="submit" onclick="displayErrorExperience(this.form)"> function checkValue2(elt, msg) { if (!elt.checkValidity()) { msg.style.visibility = 'visible'; } else { msg.style.visibility = 'hidden'; } } function displayErrorExperience(form) { var formValidity = true; for (var i=0; i<form.elements.length; i++) { if (!form.elements[i].checkValidity()) { ormValidity = false; } } if (!formValidity) { var message = "There was an error trying to submit this form:"; for (var i=0; i<form.elements.length; i++) { if (!form.elements[i].checkValidity()) { switch (form.elements[i].type) { case 'email': message += "\n Email field must contain a vaid email address"; break; case 'tel': message += "\n Telephone filed must contain a phone number in the form (xxx) xxx-xxxx"; break; } } } window.alert(message); } }

This is a simple library to make your web page shareable fast and easy.
Its allow to include the social share link of the major social network to your page.
Github repository: https://github.com/assisfery/SocialShareJS
CDN repository: https://www.jsdelivr.com/package/gh/assisfery/SocialShareJS
Just include the social-share.css and social-share.js files.
<link rel="stylesheet"<EMAIL_ADDRESS>
To have the social share buttons just put the class ss-box in one or more of you containers

If you want to select specifics social share network just add the data-ss-social attribute in your container.

For defaults the SocialShareJs put the current page location as share link but you can change it just including the data-ss-link attribute in your container.

In some of social network shares you could want to put a query string available just to specific social network,
so to do that just include
data-ss-NAME_OF_SOCIAL_MEDIA = "key1:value1, key2:value2" attribute,
for example
include data-ss-messenger = "app_id:123456", so it will include the query string &app_id=123456 in
messenger share link, or
include data-ss-email = "subject:SocialShareJS is amazing", it will include the query string
&subject=Email Subject in
email share link.

Some of buttons (like: share native ,messenger, viber and sms) perhaps
not work on desktop OS, but its works in mobile OS like Android and IOS, so may be necessary
to show that buttons only in mobile screen.
To solve that problem you could include the class ss-responsive on
your container.

If you want to show just the icons without the name of Social Network just include data-ss-content attribute with value false.

If you want to make button with circle shape just include the class ss-circle in ss-box container.

If you want to make button without rounded border just include the class ss-flat in ss-box container.

If you want to make button with pill shape effect just include the class ss-pill in ss-box container.

If you want to put shadow in button just include the class ss-shadow in ss-box container.

If you want to all your buttons have the same color just use the class ss-black (or ss-dark, ss-gray, ss-light, ss-outline) in ss-box container.

If you want to all your buttons have the same color just use the class ss-strait in ss-box container.

To create the buttons in a fixed position combine the class ss-fixed with ss-bottom, ss-top, ss-left or ss-right in ss-box container.

If you dont want to show the icons of Social Network just include data-ss-icon attribute with value false.

If you want to change the icon class of any Social Network to another icon of you
preference or icon of others packages just include the data-ss-icon-class
with value social_name1: icon_class1, social_name2: iconclass2
for example:
include data-ss-icon-class="facebook:fab fa-facebook-messenger,email:fas fa-sms" so
it will put the icon fab fa-facebook-messenger instead the facebook default icon and it will
put the icon fas fa-sms instead the email default icon.

Include ss-grow in your container to make button grow when the mouse is hover.

Include ss-shrink in your container to make button shrink when the mouse is hover.

Include ss-rotate in your container to make button rotate when the mouse is hover.

Include ss-float in your container to make button float when the mouse is hover.

If you want to create a share box in JavaScript you can use the follow function.
SocialShare.createShareBox(_elements, _link = null, _socials = null, _showIcon = true, _showContent = true, _clearContainer = true);
For example
SocialShare.createShareBox("#newShareBox", "https://github.com/assisfery/SocialShareJS", "facebook, twitter, email, sms, viber");
If you want to customize the share buttons like you want just do it adding css effect in your code.
.ss-btn{ /*your code*/ }

Interface ICompileContextProvider
Interface for an object which creates ICompileContext instances for when the system needs to compile an ITarget into an ICompiledTarget.
Namespace:Rezolver.Compilation
Assembly:Rezolver.dll
Syntax
public interface ICompileContextProvider
Remarks
In normal operation, this interface is closely related to the ITargetCompiler interface because the core ContainerBase class (which provides most of the default implementation for IContainer) obtains a new ICompileContext by resolving an instance of this interface, and calling the CreateContext(ResolveContext, ITargetContainer, IContainer) method, passing the result to the CompileTarget(ITarget, ICompileContext) method, along with the target to be compiled.
Frequently, implementations of ITargetCompiler
will also implement this interface to ensure that the compilation
context contains everything the compiler needs to do its work.
Methods
| Improve this Doc View SourceCreateContext(ResolveContext, ITargetContainer, IContainer)
Creates a compilation context for the given resolveContext - which is used to determine the RequestedType that the eventual ICompiledTarget should return.
Declaration
ICompileContext CreateContext(ResolveContext resolveContext, ITargetContainer targets, IContainer containerOverride = null)
Parameters
| Type | Name | Description |
|---|---|---|
| ResolveContext | resolveContext | The resolve context - used to get the RequestedType and the Container (if containerOverride is not provided). |
| ITargetContainer | targets | The target container that should be used to lookup other non-compiled targets. |
| IContainer | containerOverride | The container requesting the new compilation context, if different from the Container on the resolveContext |
Returns

Specific NF-kappa B subunits act in concert with Tat to stimulate human immunodeficiency virus type 1 transcription.
Abstract
NF-kappa B is a protein complex which functions in concert with the tat-I gene product to stimulate human immunodeficiency virus (HIV) transcription. To determine whether specific members of the NF-kappa B family contribute to this effect, we have examined the abilities of different NF-kappa B subunits to act with Tat-I to stimulate transcription of HIV in Jurkat T-leukemia cells. We have found that the p49 (100) DNA binding subunit, together with p65, can act in concert with Tat-I to stimulate the expression of HIV-CAT plasmid. Little effect was observed with 50-kDa forms of p105 NF-kappa B or rel, in combination with p65 or full-length c-rel, which do not stimulate the HIV enhancer in these cells. These findings suggest that the combination of p49 (100) and p65 NF-kappa B can act in concert with the tat-I gene product to stimulate the synthesis of HIV RNA.

A few years ago, I was largely ignorant of open source. I’d worked with a few products like Apache and JBoss, but was only peripherally aware of the community. I’d been doing the same kind of systems design and build work for several years, most of it Java-based middleware products like WebSphere and JBoss. I was all shell scripts and enterprise infrastructure. As I moved from client to client, I tried to automate them and enable development as much as possible via those shell scripts, but I knew nothing of formal configuration management or its associated open source tools.
In 2010 I landed on a development project at a large retail company that aimed to transform development and operations teams using Agile and Devops methodologies. This is where I first heard the terms “configuration management” and “devops.” I had no idea what was going on, no knowledge of any of the tools and just one man’s faith in my ability to pretty much do anything. He said to me, “Go learn Ruby, now go learn Chef. Now write me some cookbooks.” My first thought was, “Wtf is Chef?”
Configuration Management’s catchphrase is “Infrastructure as Code.” Server configs are declared beforehand with functional blocks of idempotent code. The code is stored in source control instead of a scripts directory on the admin server. Instead of old school, hand crafted servers, each a little unique, the configuration code is applied in a way that guarantees uniformity regardless of how many servers. Idempotent means the same configurations can be applied multiple times without unnecessary updates. These days we no longer give our servers cute names. There are too many servers and other devices for us to love and manage them individually. Chef aims to help you with that.

Over the past several months, the Rails community, at least to my eyes, has become increasingly concerned with managing the complexity that appears when following the “fat model, skinny controller” advice prescribed my many Rails experts. The real issue, however, is reusability. How can logic be easily used in two places? In your average object-oriented language, there are four primary ways to accomplish this:
- Copy and Paste
- Inheritance
- Composition
- Mixins
None are so superior to the other as to always be applicable, so how can we know when to use one over the others?
We re-use code to avoid duplication, yes, but also to get our jobs done more quickly. The form of our re-use is important, as it has the capability to change the way we’ve modeled our solution in code. And the way we model our solution in an object-oriented language is via classes, or types. We create classes that represent various domain concepts, and each class forms a type that describes what is, and is not, part of that domain concept.
Before we get into that, it’s worth talking about the most basic form of code re-use - one that we’ve all certainly used before: copy and paste.
Copy and Paste
Copy and paste is usually a sign of sloppy code, however there are two forms of re-use where copy and paste is acceptable. The first form, which I’ll call Stackus Overflowus is when you find a snippet of code somewhere that solves a problem at hand, and copy it into your codebase. Usually, it’s a small amount of code for which there is no obvious library you can pull in, and you only need said code in one location in your app. Copy and paste is the quickest way to move on, and, assuming the code is “universal”, is unlikely to need to be updated later.
The second is more subtle and rare. Suppose you have two bits of logic in your app that are identical but that are concerned with entirely different domain concepts or business processes - the code is the same by happenstance. Will it improve the codebase to extract this duplicated logic somewhere? What if these already different business processes diverge further? Now, you have to deal with making your extracted, “DRY” code deal with this divergeance.
You can actually make your app harder to change by “drying up” code that really isn’t the same by design. But, in my experience, this is rare.
More common in OO systems is inheritance.
Inheritance
Wikipedia defines inheritance as:
a way to reuse code of existing objects, or to establish a subtype from an existing object, or both
I’m going to assume single inheritance here, as that is common in common OO languages, and this means that a class only has one supertype - you get one class as your base class, and that’s it.
Re-use via inheritance is the most far-reaching and drastic - your new subclass gets the entire public interface of the superclass, plus whatever public interface it exposes on its own - as well as all the private methods and members. It’s copy and paste performed by the compiler or runtime.
Inheritance also makes a design statement - it says that the new subclass is a type of the superclass. The new class is a more specialized, less abstract version of the superclass. The runtime should treat instances of the subclass the same as instances of the superclass.
Often, however, we subclass to simply pull in code we’d like to re-use. In a rails app, all controllers inherit from
ApplicationController
. In an aging, complex Rails app, ApplicationController
becomes a dumping ground of random methods that
are needed by “a lot” of controllers - it’s effectively a global scope for code that doesn’t have an obvious place to go.
On good days, inheritance is a powerful tool to describe the types that make up your system. Code can be re-used and customized, often in ways not intended by the designer of the super class. This can be very powerful, but it can also lead to a mess. Further, it can be hard to test classes that re-use code from a superclass - just try to test an active record object without having access to the database.
Finally, inheritance brings a public interface to your subclass that you may not want. Each time you subclass, you create a class with more public methods, which actually can dilute the very types you are trying to create.
In a language like Ruby or Scala, where we have mixins (see below), I find inheritance to be useful only when I’m truly defining
a hierarchy of types - when I want to say “here is a generic type, and I’m going to make some specializations of it to avoid
massive if
statements all over my code”, or when I need to customize a type I didn’t create, for the purposes of using it with
code expecting the original type.
To get around the limitations of inheritance, the most obvious alternative is to use composition.
Composition
Composition, as defined by Wikipedia is:
a technique by which classes may achieve polymorphic behavior and code reuse by containing other classes that implement the desired functionality instead of through inheritance.
This definition is focused on where the implementation of a particular public interface lives. With inheritance, we present a
public interface whose implementation is provided by the superclass. Here, it’s done via “some other class”. In a statically
typed language like Java, composition is a pain - you have to define all the methods and proxy their calls to the composed class.
For a dynamic language like Ruby, classes like Delegator
or a well-crafted method_missing
can make this a snap.
But we’re talking about code-reuse here. As it applies to code re-use, the term “composition” colloquially means “call methods on a private object”. In other words, if I want to re-use some shared logic, I put that logic in a class, create an object of that class, and call its methods.
This has the advantage of being easy to implement and easy to understand - it’s probably what an inexperienced person would do if they didn’t know about inheritance. Using composition in this way doesn’t affect our types - our class’ public interface remains unchanged - and doesn’t require fitting our model into some complex hierarchy.
This technique has a few downsides:
- method calls are on some object, making them more verbose
- if we create said objects as needed, we make isolated testing clumsy, difficult, or even impossible
- if we instead use inversion of control and let someone else give us the objects we need, we now have to have some “container” to “wire up” all of these dependencies.
The last two issues are particularly dicey. In your average Java app, using externally configured dependency injection is the defacto standard, so you get used to writing classes based on inversion of control. In Ruby or Rails, this is not the way things work, and adding this “object container” just feels wrong. The “container” adds complexity that we’d like to avoid, even if it affords us easier isolated testing.
Is there a way to avoid the issues and restrictions around inheritance, but without the baggage of composition? There is: mixins.
Mixins
Back on Wikipedia, a mixin is defined as:
a class that provides a certain functionality to be inherited or just reused by a subclass, while not meant for instantiation
This is a bit vague, but the idea is that we can “mix in” methods from one class into another without creating a rigid, single “is a” relationship, but without also having to use complex delegation to a composed object.
Ruby uses modules for mixins, and Scala uses traits. Neither are technically classes, but they are types.
The way in which code is re-used from a mixin is identical to the way it’s done via inheritance - the methods magically appear as if part of the class. This goes for both private/protected members and public members. You can also mixin as many modules/traits as you like - there’s no practical limit.
In DHH’s blog post, he creates a mixin called Taggable
that represents “a thing that has tags”. This allows you to create a single bit of code for whatever it means to have tags, and to re-use it across the system. He describes a second mixin called Visible
that works similarly, before describing how we might use both of those in the same class.
This has a lot of positive effects:
- A single place for shared logic
- Said logic is available expediently - no need to call methods on another object
- No need to manage instances of other objects or worry about inversion of control
- Isolated testing is much simpler than with inheritance
This sounds like a pretty awesome solution to the problems presented by both inheritance and composition. So, what’s the problem?
The “abuse cases” of mixins are particularly annoying. Case #1 involves including “too many” mixins. Since a mixin can contain public members, namely methods, a class with a lot of mixins will have a very large public footprint. The resulting objects begin to move away from a “type” toward a “god object”. The rules of coupling and cohesion start to come into play, and you can end up with a system where changes to a module that’s frequently included can have disastrous effects. Making this mess with inheritance or composition is much more difficult.
Of course, no technique should be dismissed because those with bad design taste abuse it. I find a good rule of thumb is in how
these mixins are named. Mixins names should adjectives, not nouns or verbs. Although DHH refers to this pattern as “concerns”,
you’ll notice that none of his mixins are named “Concerns”. He doesn’t have a PersonConcerns
module, but instead has
modules for various features to be added.
Abuse case #2 is a misguided attempt at code organization. To feel better about creating bloated god objects, developers will extract groups of possibly-related functionality into a mixin and then mix it into the main class. This is hiding the problem of a bloated class that does too much. Preventing this is easy - if your mixin isn’t being used by more than one class then it should not have been extracted (the naming rule helps, too - if you can’t name something you’re less likely to extract it)
There’s an interesting footnote of sorts to this technique, and that is DCI - Data, Context, and Integration.
I really don’t understand DCI, but
Jim Gay’s Clean Ruby is an in-progress treatise on the DCI, and I’ve not read the entire thing, nor will I claim to understand DCI beyond examples I’ve read, including Jim’s recent post. But the examples are interesting.
In the classic use of mixins, one declares the modules to be mixed-in as part of the class definition. In the examples around
DCI, however, one mixes-in the needed code only when needed. So, a Person
that might need tagging would only have Taggable
mixed in when code requires the ability to tag a person. By default, a Person
would not be taggable. In Ruby, this might look like:
1 2 3 4 |
|
This sort of dynamic type manipulation is not possible in every language, but it seems interesting to me. Although it has some abuse cases that seem equally horrible to those of vanilla mixins, I can think of some legacy code that could’ve done well to have code organized this way. With “call-time mixins”, developers could add features to core objects with relative impunity, safe that their new changes wouldn’t cause regressions across the system. The idea is you add mixins for “use cases” or “roles” and that existing code, not needing these roles, will work as before, even if code somewhere else dynamically mixes in this new code.
At first blush, this seems like a great way to tame complexity in legacy apps where good design has gone out the window, and line after line of legacy code has been dropped into core classes. For a greenfield application, with careful attention to design and code cleanliness, this seems like less of a win to me, and would lead to more “surprising” code. But, I haven’t read all of Jim’s book, yet, so I look forward to him making the case.
So, always use mixins?
Mixins do hit a sweet spot, practically speaking, but they aren’t a panacea. Here’s my rules of thumb:
- Is the re-use concept an adjective? Is it needed across the system by disparate classes? Might be a mixin.
- Is the re-use concept a refinement, specialization, or customization of an existing type? Might be time for inheritance.
- Can’t figure out what to do? Use composition. Composition is always safe because it’s simple to create and use, even if it’s more verbose. Better to use composition when a mixin would do than to create a poorly-conceived mixin.
- Please be wary of copy and paste.


Electric Boat Project
Center of Innovation Boat
Sarthak, James, Tristan
Our boat fundamentally represents a speedboat design. Our hull was designed using Computer Aided Design (CAD) in the Autodesk Inventor Software. This CAD model was then 3D printed with yellow microcarbon to form the foundation of our boat.
A 9V battery supplies power to a standard DC motor which causes the propulsion for our boat. The motor sits at an approximate 45 degree angle and rotates the propellor attached to it.
Below is a schematic of our boat with measurements in inches noted on the inside of the hull. This schematic was designed in Autodesk Inventor and was the model used for the 3D printing of our boat's hull.

This is a rebuild of the GBE-D (Growing Beyond Earth - Digital) box which was designed for stand-alone use without internet access. The screen code has been stripped out, though the LED light pannel control remains. Sensors are re-wired for MongoDB storage and sending to MQTT. This version assumes internet access for cloud storage of data (MongoDB) and MQTT activities. There is a Flask website set up to give a view into the box. Current website is a modification of the MVP website.
Documentation can be found at: GBE_T wiki

Create your project with our distribution package.json. After downloaded, run npm install
and start writing your application:
Important note about customized package.json:

with the window
-object passed through, something "itsa"
does under the hood. When requiring this module yourself, you need to use this approach:
{% highlight js %}
var window = require('node-win'),
{{ page.itsaclassname }} = require('{{ page.module }}')(window);{% if page.extracodefirstpar %}
{{ page.extracodefirstpar }}{% endif %}
{% endhighlight %}
In the browser:
{% include loader.html %} {% highlight js %} {% endhighlight %}When using your own customized build-file, this module-requirement needs to be invoked with the window-object.
