Examination Stress : how to face it?

1. focus on the fundamentals of each subject: a twisted problem can be solved, if your concepts are very clear
2. try to UNDERSTAND and solve numericals, especially the SOLVED EXAMPLES portion from at least 2 good books
3. have confidence in yourself: that you also can do things, as others do
4. have a quick revision of each paper and spend 20% of your study time to think about the technical details for good memory-retention: THIS STEP IS EXTREMELY IMPORTANT.
5. YOU MAY SELECTIVELY LEAVE SOME COMPLEX TOPICS
6. PREVIOUS YEARS' PAPER MUST BE CONSULTED TO PLAN YOUR FOCUS BEFORE THE EXAMS
7. YOU MAY TAKE SOME MULTIVITAMIN FOR HEALTH
8. DRINK LARGE QUANTITY OF WATER FOR FITNESS
9. TAKE YOGIC EXERCISE TO FEEL STRONG
10. BE COOL ALL THE TIME...

M-circles and N-circles in control systems

Control systems (EI and ECE)

Suggested Readings on Control Systems( EI and ECE )

Books to be consulted:
1. Saeed Hasan
2. D. Roychoudhury
3. BS Manke
4. AK Jairath

For both EI and ECE :

5. Modeling of systems, Difference between Closed Loop and Open loop systems, Block Diagram Reduction, and Mason’s gain formula for Signal Flow Graphs are very important

6. Solve as many numericals as possible from Routh-Hurwitz criterion( if possible pl. refer to the book by AK Jairath)

7. Drawing of Bode Plot and finding GM and PM is most important for exams.

8. Finding Transfer Function from a given Bode magnitude plot is also important(refer. AK Jairath)

9. Cover all the sub-topics on Root-locus to be able to solve any problem on Root-locus , as a question on Root-locus(similar to solved examples of BS Manke’s book) will be given. Finding the intersection will the imaginary axis is very important, along with finding centroid etc.)

10. Pl. try to memorize standard polar plots so that problem on Nyquist Plot could be solved( pl.note that the solution is really time-consuming)

11. A highly scoring area is : time-response analysis from 2 questions are expected)

12. Realization of PID control etc. should be covered from Ogata’s book, in addition to s-domain analysis

13. You can expect one numerical problem from Lead or Lag compensator design

For ECE students some additional topics need be studied seriously:

1. describing function analysis and phase plane analysis is most important
2. one problem on Lyapunov Stability is expected
3. problems on z-transform and inverse z-transform are really important
4. Highest importance needs be attached to problems on State Variable Analysis:
Solution of state equation, finding transfer matrix, finding state model from a given transfer function, test for controllability and observability should be at your focus

Suggested Readings and some study materials

As per the desire of some of my students,
Suggested readings and some study materials on CONTROL SYSTEMS,DIGITAL ELECTRONICS, ELECTRONIC SYSTEM DESIGN will be available from tomorrow after 2.00 pm.
Sorry for the delay...

A symbol of peace...

On 24.11.2009, I paid a visit to Adyapith_Dakshineshwar from where I went to SriKrishnadas Ashram, at Mangalghat near Adyapith. I have never experienced such peace and tranquility before. The meditative silence in the ashram really overwhelmed my mind and body. I wish to go that place whenever I get some spare time.
It's an ideal place for meditation.
I think peace-loving people will be able to enjoy silence and peace in a dignified way, totally free of cost...

God bless...

Grit to defeat Failures

I have attended a lecture session by MD, Acclaris India, Mr. Kalyan Kr. Kar. I was spell-bound to hear the success story of his company. A series of entrepreneurial failures in his life could not stop him from trying out new ventures, and finally he came out with flying colours.
It happened to him and he did not have enough money to sustain a good family life , many times in his career. But the only he did : kept fighting for creating wealth and employment for the himself and the society by sheer grit,determination, honesty, and hard work...
I am trying to learn a lot of lessons from his life.

it's a geat experience to directly listen to a man who believes in fighting for a mission in life

I wish to remind myself that NO EDUCATION IS EVER COMPLETE, HENCE LET ME LEARN...
God bless...

Fear destroys the body and mind of a being...

To be fearless, we must ignite our minds with true knowledge...the science and art of self-realization...

We should remain prepared for the worst cases in all matters of life.

We must remember Swamiji's saying: STRENGTH IS LIFE,WEAKNESS DEATH.

I believe that in general, the world pays respect to the Strongs and hates the Weaks.

Hence we should try to be strong in all the three aspects of life...namely body-mind and spirit.

To be afraid of a human being is a personal crime.
Our weaknesses should first be destroyed to become bold, courageous, and strong with one and all.
But finally the real power flows from the compassionate heart of a human being, not from the brutal power of a so-called human being...

Fear of what ?

I believe that FEAR IS THE GATEWAY TO EXPLOITATION, INJUSTICE AND DEATH.
For overcoming fear, we may take some of the following measures:
1. A practical approach to LIVE IN THE PRESENT-principle
2. to know that majority of our fears are baseless
3. to live one day at a time
4. to learn the art of practical self-defence(highest will-power as well as physical force are also needed to defeat the brute power of others)
5. to remain prepared for any eventuality in life
6. tough times never last, but tough people do...to remember this great saying
7. to increase will-power by regular prayers

Humility is the essence of Humanity...

A compassionate heart,
Knowledge with humility and hunger to know more,
A regulated life,
A few measured talks,
Systematic day's work,
A vision of the future,
Taking lessons from the past,
Focussing on the present,
Voice against injustice,
and a life of honesty and courage...
are the WINNING IDEAS OF LIFE that nurtures true Humanism, Happiness and Peace...
Our thoughts and attitudes to life can do miracles for us...

2. Technical skills on at least 3 core subjects
3. fluency development in English-speaking

&

should continually be engaged in developing newer application-ideas,,,

Finding new ways of teaching Mathematics...

1. Each theoretical concept should be followed by illustrative examples
2. to discuss the application-aspect of each concept/formula
3. summarization of each lecture in tabular form
4. encouraging interaction all the time
5. enough problems as part of home-work
6. understanding problems from students' view-point
7. understanding difficulties of the students
8. stressing upon the most fundamental aspects and graph-sketching, again and again in the simplest language
9. the approach should be 'play with Maths' to create interest in the subject of Mathematics

Creative Living...

I tried to find out ways for better living for last few years. I try to implement some of these principles on a daily basis:

1. spending 30 minutes on yoga everyday,
2. switching off mobile phone while sleeping,
3. saying 'no' clearly to what I do not like , at the very outset,
4. going to bed at the same time every night,
5. self-studies for 1hour everyday,
6. spending enough time with family members,
7. writing new ideas in a diary,
8. finding new ways earning money through honest means only,
9. evolving innovative ways of teaching various subjects.
10. keeping myself aloof from all kinds of troubles...
