Points to Inspire Great Teamwork

1. Individual commitment to a group effort--that is what makes a team work.

2. Talent wins games, but teamwork and intelligence wins championships.

            3. Teamwork is the ability to work together toward a common vision. The ability to   

                 direct individual accomplishments toward organizational objectives. It is the fuel that

                 allows common people to attain uncommon results.

4. Alone we can do so little, together we can do so much.

5. Remember teamwork begins by building trust.

            6. I invite everyone to choose forgiveness rather than division, teamwork over personal  

                ambition.

7. None of us is as smart as all of us.

              8. Coming together is a beginning. Keeping together is progress. Working together is  

                success.

9. If everyone is moving forward together, then success takes care of itself.

          10. The strength of the team is each individual member. The strength of each member is     

                 the team.

          11. Collaboration allows teachers to capture each other's fund of collective intelligence.

           12. It takes two flints to make a fire.

           13. Unity is strength . . . when there is teamwork and collaboration, wonderful things can     

               be  achieved.

Struggles of our Life

Struggles of our Life

Once upon a time a daughter complained to her father that her life was miserable and that she didn’t know how she was going to make it. She was tired of fighting and struggling all the time. It seemed just as one problem was solved, another one soon followed. Her father, a chef, took her to the kitchen. He filled three pots with water and placed each on a high fire.

Once the three pots began to boil, he placed potatoes in one pot, eggs in the second pot and ground coffee beans in the third pot. He then let them sit and boil, without saying a word to his daughter. The daughter, moaned and impatiently waited, wondering what he was doing. After twenty minutes he turned off the burners. He took the potatoes out of the pot and placed them in a bowl. He pulled the eggs out and placed them in a bowl. He then ladled the coffee out and placed it in a cup.

Turning to her, he asked. “Daughter, what do you see?” “Potatoes, eggs and coffee,” she hastily replied.

“Look closer”, he said, “and touch the potatoes.” She did and noted that they were soft.

He then asked her to take an egg and break it. After pulling off the shell, she observed the hard-boiled egg.

Finally, he asked her to sip the coffee. Its rich aroma brought a smile to her face.

“Father, what does this mean?” she asked.

He then explained that the potatoes, the eggs and coffee beans had each faced the same adversity-the boiling water. However, each one reacted differently. The potato went in strong, hard and unrelenting, but in boiling water, it became soft and weak. The egg was fragile, with the thin outer shell protecting its liquid interior until it was put in the boiling water. Then the inside of the egg became hard. However, the ground coffee beans were unique. After they were exposed to the boiling water, they changed the water and created something new.

“Which one are you?” he asked his daughter. “When adversity knocks on your door, how do you respond? Are you a potato, an egg, or a coffee bean?”

Moral:

In life, things happen around us, things happen to us, but the only thing that truly matters is how you choose to react to it and what you make out of it. Life is all about leaning, adopting and converting all the struggles that we experience into something positive.

The Alphabet

Although things are not perfect

Because of trial or pain

Continue in thanksgiving

Do not begin to blame

Even when the times are hard

Fierce winds are bound to blow

God is forever able

Hold on to what you know

Imagine life without His love

Joy would cease to be

Keep thanking Him for all the things

Love imparts to thee

Move out of “Camp Complaining”

No weapon that is known

On earth can yield the power

Praise can do alone

Quit looking at the future

Redeem the time at hand

Start every day with worship

To “thank” is a command

Until we see Him coming

Victorious in the sky

We’ll run the race with gratitude

Xalting God most high

Yes, there’ll be good times and yes some will be bad, but…

Zion waits in glory…where none are ever sad!

Semiconductor Devices Numbering System

Semiconductor Devices Numbering System

From the semiconductor engineering came to existence, several numbering systems were adopted by different countries. However, the accepted numbering system is that announced by by Proelectron Standardisation Authority in Belgium. According to this system of numbering semiconductor devices:

Every semiconductor device is numbered by five alpha- numeric symbols, comprising either two letters and three numbers ( e.g.BF 194) or three letters and two numbers (e.g. BFX63). When two numbers are included in the symbol (e.g.BFX63) the device is intended for industrial and professional equipment. When the symbol contains three numbers ( e.g. BF194), the device is intended for entertainment or consumer equipment.

The first letter indicates the nature of semiconductor material. For example:

A= Germanium, B =silicon, C= gallium arsenide, R= compound material (e.g. Cadmium sulphide)Thus AC125 is a germanium transistor whereas BC149 is a silicon transistor.

The second letter indicates the device and circuit function.

Letter	Device and circuit function
A	Diode
B	Variable capacitance diode
C	A.F. Low powered transistor
D	A.F. Power transistor
E	Tunnel diode
F	H.F. Low power transistor
G	Multiple device
H	Magnetic sensitive diode
K	Hall effect device
L	H.F. Power transistor
M	Hall effect modulator
P	Radiation sensitive diode
Q	Radiation generating diode
R	Thyristor ( SCR or triac)
S	Low power switching transistor
T	Thyristor (power)
U	Power switching transistor
X	Diode, multiplier
Y	Power device
Z	Zener diode

MY EXPERIMENTS WITH TEACHING

These years, Engineering inspires and fancies students about being a TCSian or a product of cognizant. When my friends entered into the corporate world, I was looking at the dark sky at night thinking ‘what was my future’ with every usual homosapien on the earth fighting to breathe or live. And with the feeling of my boat has drowned and I slept. Perhaps I didn't know that I was going to take up a very powerful Profession later.

It was the time when I started my post graduation. One fine day, I got the offer to teach the polytechnic girls. I was very thankful to God.  Initially, I had all colours of dream and passion yet didn't know what to paint. With no expectations from my side and not knowing what their expectation from me was, I started the so called career as a TEACHER.

The first day was exhilarating and bizarre. I had a 180 degree glance at the class and don’t know what to talk. I introduced myself to the class and asked them what their expectation from me was. A girl boldly declared, ‘we want you to be friendly and please don’t demand anything from us’. I got shocked looking at the mannerism of the student with teacher. O! My God! what a generation gap!  I did not express what I felt in my heart but said, ‘You are a brave girl. But I can’t assure you with what you asked me unless you do what I want’. Her eyes went small. I walked towards the center of the class and framed my rules, ‘You are free to ask anything from me related to subject and every day I would like to have a small oral test. At the end of the week you will have a unit test’. The class went into deep silence. I started my first class normally and observed them carefully.

That day I was thinking a way to bring an interest for the subject computer architecture that I handled for them. I decided not to look at notes when taking class and put a lot of effort on my side. I worked on what will make them to throw their minds towards the subject.

Next day I went with lots of happiness and curiosity to start my experiments with the students. I didn't carry any notes and went hands free. Boldly, I started my lecture. A girl in front put a stand for her cheek. I turned and split the board into two. She opened her notebook immediately. I felt comfortable with what I was doing. Soon there was much concentration and brightness in their faces. I followed four important tactics for their attention

1. I drew the block diagrams for example data bus using multiplexer without looking the text or any material. This will definitely draw their attention.I also taught them how to draw it. I insisted which should be drawn first and then next and later connect them logically.

2. Often I went around the class and spared some time with those who struggled.

3. Started the class always with oral question and answer. Punishments were like they should learn a block diagram and draw it on the board.

4. I dictated the definitions and very important points.

The first and foremost point required lot of hard work. Because without practice of diagrams before will not help you at the board. And I dictated the definitions at the middle of lecture without looking at any notes. To do this, one must take some care for we should not blabber anything as they are writing down. Also the students don't even know how to draw a diagram logically. I practiced these tactics and they started doing what I wanted from them. I completed that semester with successful teaching.

What I inferred was students completely replicate what we are inside the class. The more I was serious about the subject the more sincere they became. And later I did what the girl wanted from me. I developed a good rapport with them.  Also they did anything without any demands. I was invited for a farewell function for the final year students. I could see my students like angels dressed so well. I was admiring them as a teacher.

Later I got into DCE and my thirst for new venture started all over again.

This small article is just a small drop in an ocean. Depending on conditions these will change. It’s not any periodic procedures to follow but I just want to share my first experiences….
