Move Over Megapixel...Gigapixel Technology on Its Way

A camera capable of creating images with "unprecedented detail" has been unveiled by US engineers.


Nowadays, the typical commercial digital camera is capable of taking photographs ranging from 8 to 40 megapixels, but a new prototype machine, dubbed AWARE2, is threatening to make these cameras obsolete.


It works by synchronising 98 tiny cameras in a single device.


The machine is likely to be used first for military surveillance.


"A computer processor essentially stitches all this information into a single highly detailed image. In many instances, the camera can capture images of things that photographers cannot see themselves but can then detect when the image is viewed later."


By utilizing 98 tiny synchronized cameras, AWARE2 captures images with resolutions of up to 50 gigapixels, the equivalent of 50,000 megapixels


Though AWARE2 is too bulky and impractical for handheld use and will likely initially be used exclusively for military surveillance, researchers expect that gigapixel cameras will be compact enough to be made available to the general public within five years.

What are the Best and Effective study techniques?

No two people study the same way, and there is little doubt that what works for one person may not work for another. 


However, there are some general techniques that seem to produce good results. No one would argue that every subject that you have to take is going to be so interesting that studying it is not work but pleasure.


Effective Study skills are about more than understanding

Effective study skills must be practiced in order for you to improve. It is not enough to simply "think about" studying; you have to actually do it, and in the process use information from what you do to get better. This is the central idea of this page. All that follows depends on this single concept. There is a saying that goes like this: "Practice doesn't make perfect; perfect practice makes perfect." If you want to be an achiever, take this saying to heart.
The value of a schedule
Before you even begin to think about the process of studying, you must develop a schedule. If you don't have a schedule or plan for studying, then you will not have any way of allocating your valuable time when the unexpected comes up. A good, well thought out schedule can be a lifesaver. It's up to you to learn how develop a schedule that meets your needs, revise it if necessary, and most important, follow it.
Making every hour count
A schedule should take into account every class, laboratory, lecture, social event, and other work in which you engage. There are givens such as classes and so on that have to be incorporated. You must focus on the other "free time" available and how you will use it.
Making and revising a schedule
Don't be afraid to revise your schedule. Schedules are really plans for how you intend to use your time. 

The Process of Study

How to use your time
The schedule you develop should guide you in how to allocate the available time in the most productive manner. Sticking to your schedule can be tough. Don't dribble away valuable time.
Where to study
You can study anywhere.Libraries, study lounges or private rooms are best.The place you choose to study should not be distracting.
Strategies
Thinking skills
Everybody has thinking skills, but few use them effectively. Good thinkers see possibilities where others see only dead-ends. If you're not a good thinker, start now by developing habits that make you ask yourself questions as you read.


The SQ3R method


SQ3R stands for Survey, Question, Read, Recite, Review. 


Survey - get the best overall picture of what you're going to study BEFORE you study it an any detail. It's like looking at a road map before going on a trip.
Question - ask questions for learning. Questions should lead to emphasis on the what, why, how, when, who and where of study content. Ask yourself questions as you read or study.
Read - Reading is NOT running your eyes over a textbook. When you read, read actively. Read to answer questions you have asked yourself or questions the instructor or author has asked. Always be alert to bold or italicized print. Often times tables, graphs and illustrations can convey an idea more powerfully than written text.
Recite - Try to recall main headings, important ideas of concepts presented in bold or italicized type, and what graphs charts or illustrations indicate. Try to connect things you have just read to things you already know.
Review - A review is a survey of what you have covered. It is a review of what you are supposed to accomplish, not what you are going to do. Reread with the idea that you are measuring what you have gained from the process. The best time to review is when you have just finished studying something. Before an examination, do a final review.

Reading

A primary means by which you acquire information is through reading.
Getting the Main Idea
You must learn what the author's central idea is, and understand it in your own way. 
Extracting Important Details
There is usually one important detail associated with every main idea .You need to make a link between an idea and information that supports it.That will make your reading and understanding easier.

Taking Notes

Like reading, note-taking is a skill which must be learned and refined.
Where to Keep Notes
You must learn to keep notes logically and legibly. Remember, if you can't read your own writing a few days after taking notes, they are of little use.
Outlining Textbooks
First of all, don't underline. Use a highlighter. Experience has shown that text passages highlighted are more easily remembered than the same passages underlined.
Taking Lecture Notes
Surveying, Questioning, Listening
Taking accurate and concise lecture notes is essential. Develop the habit of taking notes using appropriate methods described earlier in the SQ3R technique.
Reviewing and Revising
As you prepare for examinations, tests, or other assessments, you should spend time reviewing and revising your lecture notes.
Enjoy Reading

This is a long guide. But this can be a very much beneficial and important to you to get success in every exams.just relax and follow the above mentioned steps and points . You will definitely feel it worthwhile.Enjoy...And All The Best....
Be Happy Be Logical :)
