Some Facts About computer world

• The real name of “the” Bill Gates is William Henry Gates III. Nowadays he is known as Bill Gates (III). By converting the letters of his current name to the ASCII-values and adding his (III), you get the following:
B 66
I 73
L 76
L 76
G 71
A 65
T 84
E 69
S 83
I 1
I 1

Facts about Human Body

May 11, 2010 at 1:45 AM | Posted in Fun | 1 Comment

This week when i was surfing the web came across some unusual things about human body that i didn’t know about, then i thought to put this on my Blog apart from technical things

— A person will die from total lack of sleep sooner than from starvation. Death will occur about 10 days without sleep, while starvation takes a few weeks.

— A cough releases an explosive charge of air that moves at speeds up to 60 mph

— A sneeze can exceed the speed of 100 mph.

— An average human drinks about 16, 000 gallons of water in a lifetime.

— An individual blood cell takes about 60 seconds to make a complete circuit of the body.

— Babies are born with 300 bones, but by adulthood we have only 206 in our bodies.

— Beards are the fastest growing hairs on the human body. If the average man never trimmed his beard, it would grow to nearly 30 feet long in his lifetime.

— Every person has a unique tongue print.

— Humans shed and re-grow outer skin cells about every 27 days – almost 1,000 new skins in a lifetime.

— If it were removed from the body, the small intestine would stretch to a length of 22 feet.

— It takes 17 muscles to smile — 43 to frown.

— Jaw muscles can provide about 200 pounds of force to bring the back teeth together for chewing.

— Lab tests can detect traces of alcohol in urine six to 12 hours after a person has stopped drinking.

— Laughing lowers levels of stress hormones and strengthens the immune system. Six-year-olds laugh an average of 300 times a day. Adults only laugh 15 to 100 times a day.

— On average women say 7,000 words per day. Men manage just over 2000.

— One in every 2000 babies is born with a tooth.

— The ashes of the average cremated person weigh nine pounds.

— The average adolescent girl has 34,000 underdeveloped egg follicles, although only 350 or so mature during her life (at the rate of about one per month).

— Most men have erections every hour to hour and a half during sleep.

— The average human body contains enough: iron to make a 3 inch nail, sulfur to kill all fleas on an average dog, carbon to make 900 pencils, potassium to fire a toy cannon, fat to make 7 bars of soap, phosphorous to make 2,200 match heads, and water to fill a ten-gallon tank.

— The average human produces 25,000 quarts of spit in a lifetime, enough to fill two swimming pools.

— The human brain is about 85% water.

— The largest cell in the human body is the female ovum, or egg cell. It is about 1/180 inch in diameter. The smallest cell in the human body is the male sperm. It takes about 175,000 sperm cells to weigh as much as a single egg cell.

— The most common blood type in the world is Type O. The rarest, Type A-H, has been found in less than a dozen people since the type was discovered.

— The sound of a snore (up to 69 decibels) can be almost as loud as the noise of a pneumatic drill.

— Three-hundred-million cells die in the human body every minute.

— Women burn fat more slowly than men, by a rate of about 50 calories a day.

— Women’s hearts beat faster than men’s.

Week 10

May 5, 2010 at 11:17 PM | Posted in Stuff, Videos | 5 Comments

This week we didn’t have to answer any Questions and didn’t have to find meanings for anything….. basically we do nothing officially but as we are IT students we have to do heaps of stuff unofficially (Back-end Work)…. 🙂

This week i was looking for Acadamic paper for part 2 of assignment 2, here is the link for my academic paper

here is another video related to my area of Interest

Week 9 Qualitative & Quantitative research

April 28, 2010 at 5:56 PM | Posted in Q&A | Leave a comment

Quantitive Research is also used to study human behavior in different situations, but in Quantitive Research we don’t concentrate on reasons of the human behavior. Quantitive Research is investigation of something with mathematical approach. example of Quantitive research is Voting in elections for someone and after that the person with highest votes win.

Qualitative Research is used to study human behavior and the reasons behind every action of human behavior in different situations. Qualitative Research put more emphasis on Why and how a decision is made instead of What, where, when. example of Qualitative Research is why someone has voted for particular person.

The difference between Quantitative and Qualitative research is just the way we research. one research approach is look for the reason behind the human behavior and the other looks for the amount of same human behavior no matter what is the reason. and both research methods fall in social science paradigm.

8 different research Methods

Quantitive Research Approaches
1. Survey
2. Econometrics
3. Voting

Qualitative Research Approaches
4. Case Study
5. Grounded Theory
6. Phenomenology
7. Ethnography
8. Historical

Note: There are more research approaches available, these are few i have taken for example.

Week 6 Exercise

March 31, 2010 at 12:02 AM | Posted in Q&A | Leave a comment

I have found two Academic Research for designing PCBs both the paper focused on the specific Issue of PCB
P Johnston – Journal of Surface Mount Technology, 1996 –

I have found these paper in Google Scholar the Keyword I used is “designing Printed circuit board”

3 reason why i believe these are research papers are
1. Both papers were published in journals.
2. The Abstract of both the papers answer all 3 questions Dr. Clare asked
3. Both papers have most of the components of academic research paper like tittle, abstract, conclusion, introduction and etc….

Did the abstract tell you the three things I said it should?
Yes the Abstract of both paper answers the 3 question you asked….

What seems to be the question(s) they were trying to answer?
First Paper,
What is the layout guide for designing system cards which incorporate ball grid array packages.

Second paper,
The effectiveness of embedded capacitance for reducing power-bus noise in high-speed printed circuit board designs.

Briefly describe the method(s) they used to answer the questions(s)
I don’t know the answer of this question because i haven’t read the paper throughly…..

Did you agree with what they wrote in their conclusion?
Yes i do agree with what they wrote in the conclusion of both papers. But the first paper doesn’t answers the question i identified deeply.

How many references does the paper have?
First paper got none references but that paper have acknowledgement at the end, i don’t know whether it is considered as a reference or not….
Second paper got 6 references.

Briefly describe two things that you learnt from the paper
First paper,
1. I have learnt about the BGA (ball grid arrays). I have seen BGAs before but i didn’t know that these were BGAs. BGA is used By Intel, Nvidia and other companies as well there is picture of a Nvidia card with BGA

2. Wiring patterns can reduces the number of layers in a PCB

Second paper,
1. The physical decoupling capacitors can be embedded on PCB it Self but with proper designing.
2. I haven’t heard about the MCM (multichip module). I learnt about MCM as well from this paper.

Video for area of Interest

March 30, 2010 at 10:36 PM | Posted in Stuff, Videos | Leave a comment

I was looking for the video for designing the PCB(Printed Circuit Board)….. this video is from NexLogic Printed Circuit solutions established in 1995 in USA…… when i was watching the video i saw the pick and place machine used for SMDs(surface mount devices) then i searched for speed then come to know that…. the average speed of Pick and place machine can be from 8000 to 36000 components per hour depending upon the components “its amazing”….

Week 5 Exploring my Interest 2

March 24, 2010 at 2:43 PM | Posted in Q&A | 2 Comments

My interest is in Designing the PCBs for the CPU…… all the CPU is basically PCBs like Mother Board, RAM, Interface Cards, Hard drives and other things…… this topic is right on the edge of IT and falls under the electronics field but when we deal with CPU it still counts as IT….

Things I know about designing PCBs
• I know How to design single layer PCBs
• I know we can design double layer and multi layer PCBs
• I know we can use software for designing PCBs

Things I Believe about Designing PCBs
• Every portable device in the world have at least one in it
• Lots of experiments are going on to shrink the PCBs
• PCBs are the soul of CPU….

Things I don’t Know about Designing PCBs
• I don’t know how many maximum layer can we have for multi layer PCBs
• I don’t know how to mount devices on Multilayer PCBs
• I don’t know how to use the software for designing multilayer PCB
• Can we make a single multilayer PCB or it is supposed to be on large scale?
