INTERVIEW AND SHORT ANSWER QUESTION ON IMAGE PROCESSING-BIOMEDICAL JOBS & NOTES QUESTION 41-60
41. What are the applications of transform.
1) To reduce band width
2) To reduce redundancy
3) To extract feature.
42. Give the Conditions for perfect transform?
Transpose of matrix = Inverse of a matrix.
Orthoganality.
43. What are the properties of unitary transform?
1) Determinant and the Eigen values of a unitary matrix have unity magnitude 2) the entropy of a random vector is preserved under a unitary Transformation
3) Since the entropy is a measure of average information, this means information
is preserved under a unitary transformation.
INTERVIEW AND SHORT ANSWER QUESTION ON IMAGE PROCESSING-BIOMEDICAL JOBS & NOTES QUESTION 21-40
21. Define subjective brightness and brightness adaptation?
Subjective brightness means intensity as preserved by the human visual system.
Brightness adaptation means the human visual system can operate only from
scotopic to glare limit. It cannot operate over the range simultaneously. It accomplishes
this large variation by changes in its overall intensity.
22. Define weber ratio
The ratio of increment of illumination to background of illumination is called as
weber ratio.(ie) ?i/i
If the ratio (?i/i) is small, then small percentage of change in intensity is needed
(ie) good brightness adaptation.
If the ratio (?i/i) is large , then large percentage of change in intensity is needed
(ie) poor brightness adaptation.
BIOMEDICAL ENGINEERS ARE GIFTED ONES ALWAYS
There’s Smart, and then there’s Mega-Smart
Biomedical engineers are smart people; this is a universal truth. As a rule, dim-witted people do not develop bioartificial organs or design pacemakers. But then there are the pioneers who have taken the biomedical field by storm over the past century, earning more awards and patents and inventing more devices than any mere mortal should. You could refer to this rare breed as The Ridiculously Smart Bioengineering Club, a league of gifted souls with DNA like Einstein’s.
What Do They Have in Common?
Let’s start with biophysicist Otto Schmitt. Though his parents weren’t scientists, Otto was exposed at the age of 16 to the work of his older brother Frank. Frank became a professor of zoology in 1929, and Otto was allowed to “gadgeteer” in Frank’s laboratory and create instrumentation (www.thebakken.org). Otto would also do experiments at home, much to his mother’s chagrin. His mom fainted when she went into his bedroom one day and saw Otto with sparks flying out of his nose and fingers; he had crafted his own rudimentary Tesla Ball out of spare parts to make his hair stand straight up. Despite his crazy antics with electricity, Otto survived his youth and went on to invent devices like the cathode follower.
Leslie Geddes has taught one-fifth of all biomedical engineers currently in practice. He’s patented everything from a baby pacifier that delivers medication to biomaterials (www.mit.edu). As a kid, Leslie’s dad would bring home radio parts from work for his son to tinker with. Because some relatives were physicians, Leslie decided he would like to combine electronics with medicine.
Extraordinary curiosity is a common theme in the early years of the genius bioengineers. Robert Langer, currently Professor of Chemical Engineering at MIT in Cambridge, received a Gilbert chemistry and microscope set from his parents as a young boy. He was fascinated watching chemical color changes, and enjoyed watching shrimp grow with his little microscope (www.thebiotechclub.org). This young chemist would grow up to receive more than 600 patents and 160 major awards, and be the most cited engineer in history. His controlled drug delivery developments have alleviated human pain for countless patients. The stubborn Langer is oft-quoted as saying, “A lot of times somebody will tell you that your idea, or your invention, can’t be done. I think that’s very rarely true. If you believe in yourself and if you really work hard and stick to it, I believe there is very little that is impossible.”
This stubbornness gene can be found in Alfred E. Mann, entrepreneurial physicist and philanthropist billionaire. He’s said, “To say we can’t do something because other people have failed is not good enough for me” (www.inhealth.org).
It seems the formula for biomedical engineering mega-success is one part insatiable curiosity, one part influence by mentors, two parts giftedness, and three parts stubbornness.

CONVERT A STUDY INTO PAPER WRITING IN DOC DIRECTLY-JUST TWO STEPS PROCESS
Image via Wikipedia
We have seen generally that student at undergraduate level are not able to associate their study skills with paper writing capabilities, So I thought that it would be right to have a tutorial about how to extract a paper from regular study material
It could be an IEEE paper or paper being presented at any other level
what are the basic fundamental skills required for writing a paper
A major goal of this tutorial is the development of effective technical writing skills. To help you become an accomplished writer, you will prepare several research papers based upon the studies completed in lab.
convert .doc to .pdf
most of the times when we have to proof our resources and protect them from any remote acces and make them secure we prefer to use .pdf format but this format is not easy to make
this is the tool which will convert your .doc to .pdf
Universal Document Converter is the most complete solution for converting from DOC to PDF or graphical files. The underlying basis of Universal Document Converter is the technology of virtual printing. As a result, exporting any document, table or presentation into PDF format is not any more complicated than printing on a desktop printer.
