1's and 0's of engineering..

Here are a few Do's and Don'ts of Engineering life:





Be alive and active on social networks.

Waste your day playing games, talking nonsense or doing nothing. Start studying only at night, after all the sitcoms are over.

Log in to facebook first. Then only open other tabs.

Develop selective listening skills.

Discover the regular hangouts with seniors. Always be present there.

Have at least one place at college that's known just to your group.

Follow massbunks religiously.

Do not feel bad if you get an A and the one who copies your answer gets an A++.

After getting a KT in first year, cry. After entering second year, look at the first years cry after getting a KT and say, "Overacting!"

Buy easy solutions. Buy text books. Know the reference books' names and authors to tell the external examiner during vivas.

Run to save the last seat during midterm tests Make sure that you're surrounded by 2-3 who have read something.

Well begun is half done. Half done gets c+ if the examiner is attentive.

Call a friend to ask syllabus 1 day before exam.

Ask friends to tell the full form of the subject before its viva.

Group study works only when there are 3 hours left for exam. Before that, it's an # epic fail.

Check the number of pages before starting to read the chapter.

Download like there's no tomorrow. Support piracy.

Talk about everything like you know it. Especially during placements.

Forget lunch/dinner breaks when you're working for a Cultural or Technical fest.

Never skip meals for assignments and studies.

Eat junk food. You have the responsibility to save the rest from it, so finish it from the Earth!

Copy assignments. Write the master copy at least once in four years.

Xerox machine is one of your favourite Engineering miracles. Worship it.

Stay connected with the class on WhatsApp and network groups.

The canteen person should know what you're going to order as it's your regular. A professor must ask you "are you in this class? I've never seen you before. Which lecture?"

Classmates hate teachers' puppies. Professors hate cool/beautiful students. Be none.

Stay neutral. Remember, increasing your tolerance threshold is a part of Engineering,

Do not complain about not maintaining cleanliness. That concept was extinct long ago.


Professors are not supposed to teach you, you have classes for that. They exist so that you'd know how to cover entire introduction chapter in one lecture and still manage to keep students nonplussed.

Lab attendants are Gods in disguise.

Office staff will make it a point to be helpful. In lunch break they possess the powers to make you feel helpless.

If you are a girl, enter the washroom the moment you enter college. Travelling to college even for 5 minutes is harmful for your looks.

Talk shit. Find friends that like the shit you've talked. Never leave them.

If you are a guy, and you find a senior girl attractive, and-
a. if she is single. Do not mess with an unavailable chick.
b. if she's a dropper. They usually talk a lot if you can supply good notes.
c. if she is sane, confirm it.

Creative answers do not impress professors.

Be late. Lie that you missed the bus. Do NOT extend the lie.

The Requirement of Attendance Vs Hotness and Popularity graph is as follows:




Attend college on all the important days: Saaree day, Traditional day, Pink/Blue day.

Either have an impressive handwriting or pull off a clumsy one. Either ways, write a lot.

If you know the answer, write a lot. If you do not know the answer, write a lot.

No need to understand what you write, just write a lot.

First bench is a necessary evil. Trolling professors by asking doubts is best done from first bench.

Texting cannot be written as a hobby in resume.

Parents and professors should be treated as exclusive sets.


What you do, what you should be doing, what your teachers and parents think you are doing should never coincide.




Enjoy..
Have fun!!

In the light of University leaks ;)

In the light of the leaked university paper events, I have been thinking a lot about the academic corruption that the current engineering students go through. This post necessarily talks about the level of corruption, causes, effects and factors affecting it in a straight-to-the-face manner. A problem is best served with the solution, so this article also will try to set a solution in action.




Let's take a simple example under study, a masked corruption, giving out the questions for term tests to the students for preparation. Some may try to rationalize it, but that will be just like the project outsourcing trend. It is bad enough to do the wrong, but worse to justify it as the right. In Mumbai University syllabus, 25 marks called as 'term work' per subject are in the hands of the professors. The factors which determine these 25 marks are: attendance, connection with the professor, overall performance and term test marks. In some colleges, term tests are replaced by a prelim each semester, but the overall pattern is similar. Let's narrow down our scope for the purpose of study and concentrate only on the corruption at mid-term exam level, which is responsible for say, 5 marks per subject in total engineering scene.


When no questions are given for preparation:
Highest: 24. Lowest: 0.
When a question bank (5/12 expected in exam) was given: Highest, 28, lowest 2.
When the teacher gave question paper straightaway:
Highest: 29, lowest: 4.
Observations:
#1: Giving out the paper shifted the origin for obtained marks by 5, approximately 16.66% of the test, 5% of the subject and not even 1% of the total semester marks, but made the paper-checker's work easier as the graph was crowded at the correctness side.
#2: 70% of the students had prepared only 7 questions out of the expected 12 list. Number of toppers were more than those who cleared the completely clueless tests.
#3: the approximate percentage of copying was observed to decrease in the 5/12 method, but it was the same in 5/5 method.


Now, what my professor did here is, give all the questions and ask only 4 of them, with 2 unexpected questions as compulsary.
Results:

Highest: 19, lowest: 0.
Observations:
#1: Nobody had studied the 10 marks unexpected questions. Students will not study more if they are given a ready-made easy way!
#2: Toppers were still happy, as they assumed that everyone was evaluated for 20 marks out of the questions foretold.
#3: There was a material that never studied, not even the given 4 questions.


Combined Inference:
1. The half-blind horse effect:
Even though the intention was of guiding, everyone studied only what was in the expected list. A student tends to cover his eyes from the unnecessary burden wherever possible. The horse will reach the destination, but can never work out the road on its own. We're building autonomous line followers. The purpose of education is defiled, as the studying part only concentrates on known questions, leaving aside the learning process.
2. The synchronized corruption:

Corruption is a wave that will set easily if both the parties involved are at benefit. Here, both the student and the professor save time and effort in sharing questions. The disadvantages of the learning curve are compromised. Plus, the things that happen in a group are conveniently approved to be less unrighteous. A group of 75+ people sharing the same vision and motivating the deed, none pointing out that it is wrong.. ah! The tragedy.
3. Importance of the scenario:
As Gladwell tells in his book, the power of context is an important factor. If it were for a more important exam, the professors would be willing to share less, so as to let only the cream students pass. Even the students would want to avoid helping in the process of copying as there would be a greater need for competition. The fact that it's only a term test, generates a self-motivated carelessness in the victims, thus they don't bother to work hard. It is almost like you knew that the snake that bit you was non-poisonous.
Last, but not the least, the misconceptions:
there were students who were okay even with 0 marks and did not study at all, neither did they try to copy and write answers. They were harmless on copying measures, but made a negative impression on overall result. This behaviour is observed to be out of spite and that has either of the following 3 reasons: 
1. Potential dumbness/laziness.
2. Misled ideas about rebelling the education system.
3. Misconception about sounding cool by keeping an 'I don't care' attitude.


This was just a small scale example. I believe there are a number of ways in which corruption is rationalized and planted as a seed in the development cycle of today's student. Sad as it may seem, nothing is constant. The 5/12 theory is one of the possible solutions. Help them, walk them through and you might be able to convert a few students who are willing to learn the right way. Time demands a need to have faith that at least some 18 year olds will be ready to take the longer route to keep their heads up while riding on their path. They say, Dnyanina: Tatwadarshina:| Let's hope that we one day make its meaning a possibility.

I wish there were schools without an exam, without a comparison, without a judgemental degree of classification, that taught everything without a syllabus. I wish there were students who lived to learn what they loved and challenged the education system to cope up with their need for knowledge. I wish there were better measures to determine success and happiness. I wish there were no need of becoming an engineer certified by MU, to learn engineering and if it should exist, getting a degree from MU meant like becoming an engineer in true sense. And then I wish everyone one day will realize it's not something to wish for, but to use different glasses. 

Enjoy!

Hangover @ Engg

Hangover, a term coined for post high effect. The high can be a result of getting drunk or intake of drugs which it is for most of the cases OR it can be the outcome of too much happiness and peace.  I have luckily/unluckily as you define it, till date only experienced the later one.
When you are happy, you have peace of mind, love flows from heart, positive energy overflows and the ambience around you is cheerful, a periodic state that may last for hours, days or weeks. This is the time when you enjoy the true bliss of nature, new relationships are developed and stronger bonds are created. This is the time when you solve one of the trickiest mathematical questions, a time when
you come up with out of the box solutions to the practical problems, a time when you challenge yourself, a time when you truly feel for the song “ae sala, abhi abhi hua yakin ki aag hai mujme kahin”.
Everything seems so perfect.
But HELLO!!, wake up, this is life.
Life is full of ups and lows, happiness and sorrow, falling and getting up, an amazingly eventful journey (mostly unexpected) from birth to grave. The high is past now, you experience the hatred around you, you see the competition around you, negative energy simply flows around, and you fight for survival. The interest in passion is lost and everything seems hazy. You are in the Hangover mode, you experience the real world, and you live the real LIFE. One searches for pleasure and tries new ways to meet it.
Lack of motivation, deviation from the decided path, change of ambience in terms of people, places or objects can be few among other reasons. As we grow up the percentage of time we experience the hangover increases. We need a constant source of inspiration, a motivation to move ahead and an urge to submerge in positive energy.
We should try to decrease the period of hangover, stay high and try to be happy ; not due to the intake of an external source but as a result of peace within, the love within. We must strengthen the self confidence and have faith in ourselves. Once we generate the equation of happiness, know the source of love, most of the challenges which seemed impossible may now seem reachable. Higher heights can be achieved, true bliss of mother nature can be experienced, stronger bonds can be created, and its possible to now fly, high up in the sky.
So fly high..
Enjoy life !! :)

Easy circuit analysis

Three Essential Laws for Working with Circuits

At the most basic level, analyzing circuits involves calculating the current and voltage for a particular device. That’s where device and connection equations come in. Device equations describe the relationship between voltage and current for a specific device. One of the most important device equations is Ohm’s law, which relates current (I) and voltage (V) using resistance (R), where R is a constant: IR or V/R or R = V/I.
The two connection equations you need to know are Kirchhoff’s current law (KCL) and Kirchhoff’s voltage law (KVL):
  • Kirchhoff’s current law: Sum of incoming currents = Sum of outgoing currents at a node
  • Kirchhoff’s voltage law: Sum of voltage rises = Sum of voltage drops around a closed loop

Electrical Quantities and Units of Measurement

Certain electrical quantities, relationships, and electrical units are critical to know when you’re analyzing and characterizing circuit behavior. The following table can help you keep this information straight.

Equivalent Resistance, Capacitance, and Inductance

When analyzing circuits, you can simplify networks consisting of only resistors, capacitors, or inductors by replacing them with one equivalent device. The following equations show equivalent series and parallel connections for resistor-only, capacitor-only, and inductor-only combinations.

Analysis Methods for Complex Circuits

When dealing with complicated circuits, such as circuits with many loops and many nodes, you can use a few tricks to simplify the analysis. The following circuit analysis techniques come in handy when you want to find the voltage or current for a specific device. They’re also useful when you have many devices connected in parallel or in series, devices that form loops, or a number of devices connected to a particular node.
  • Node-voltage analysis: Nodes are particular points in a circuit. When many devices are connected to a particular point, you can make this node a reference node and think of it as having a voltage of 0 V. You then use it as a reference point to measure voltage for a particular node.
    With node-voltage analysis, you find unknown node voltages in a circuit using Kirchhoff’s current law. After finding the node voltages, you use current-voltage (i-v) relationships such as Ohm’s law to find device currents and use the node voltages to find device voltages.
  • Mesh-current analysis: mesh is a loop with no devices enclosed by the loop, where the mesh boundaries are those devices that form the loop. Mesh-current analysis lets you find unknown mesh currents in a circuit using Kirchhoff’s voltage law (KVL). Mesh equations are KVL equations with unknown mesh currents as variables. After finding mesh currents, you use i-relationships to find device voltages.
  • Superposition: For linear circuits with independent sources, you can use superposition to find the voltage and current output for a particular device. Superposition involves turning on sources one at a time while turning off the other sources. You turn off a current source by replacing it with an open circuit, and you turn off a voltage source by replacing it with a short circuit. To get the total output, you calculate the algebraic sum of individual contributions due to each source.
  • Thévenin/Norton equivalents: Circuit analysis can become tedious when you’re trying different loads with the same source circuit. To save yourself some work, replace the source circuit with the Thévenin and Norton equivalents. Thévenin’s theorem says you can replace a linear network of sources and resistors between two terminals with one independent voltage source (VT) in series with one resistor (RT), and Norton’s theorem says you can replace the linear network of sources and resistors with one independent current source (IN) in parallel with one resistor (RN) — see the following figure. The equivalent circuits will hold for all loads (including open and short circuit loads) if they have the same voltage and current relationships across the terminals.
    Finding the Thévenin or Norton equivalent requires calculating the following variables: VT VOC, IN =ISC, and RT = RN VOC/ISC (where T stands for Thévenin, OC stands for an open-circuit load, Nstands for Norton, and SC stands for a short circuit load). When you want to analyze different loads connected in series with the source circuit, the Thévenin equivalent is useful; when loads are connected in parallel with the source circuit, the Norton equivalent is a better choice. The two equivalents are related to each other by a source transformation.
