Diabetic retinopathy (DR) is a complication resulting from the diabetes. According to the National Eye Institute estimation 40-45% of the diabetics suffer from certain level of diabetic retinopathy. The estimated incidence rate of DR is 30% and 80% respectively for diabetics with 5 and 15 years of history. DR is classified into two categories, four stages: (Mild, moderate and severe) non-proliferative retinopathy, and profilerative retinopathy. Early detection of DR allows timely therapeutic treatments to slow down the DR development.

Extending the Reach of the White Cane for Blind Wheelchair Users

Week: March 11 - March 18, 2011
Keywords: Computer Architectures, Algorithms, Security

Modern networks need to be constantly on the prowl for the bad guys: worms, intruders, denial-of-service attacks, etc. As we learn more information about the way these bad guys attack our machines we can start to develop rules - or specifically sequences of text - that tell us that an attack is occurring. The problem is that this list of rules already has more than 100,000 entries, and is growing larger by the second. While that does not sound too bad, the problem is that we want to search every byte of every pieces of data sent over the internet for each and every instance of these 100,000 rules - many billions of characters of text each and every second.

Extending the Reach of the White Cane for Blind Wheelchair Users

Week: March 4 - March 11, 2011
Keywords: Human computer interaction, Computer Vision

Approximately one in ten blind persons uses a wheelchair, and independent travel is extremely difficult for this population. With funding from the NSF, the Smith-Kettlewell Eye Research Institute has developed a prototype computer vision system at that allows a visually impaired wheelchair rider to "interrogate" the environment using a standard white cane to detect important terrain features such as obstacles and curbs. This system allows the user to interrogate the environment by sweeping a standard (unmodified) white cane (which a visually impaired rider is already likely to be using) back and forth, from left to right. Using a pair of video cameras mounted on the wheelchair facing the path ahead, the system continuously tracks the cane location and sounds an audio alert if a terrain feature is detected in the direction the cane is pointing. Thus, the user interface extends the reach of the white cane in a seamless and intuitive way while permitting normal use of the cane.

CSAIL Zooms In With Computational Photography

Week: February 28 - March 1, 2011

Breaking the O(n^2) Bit Barrier

Week: January 7 - 14, 2011
Keywords: Scalable Byzantine Agreement

The paper "Breaking the O(n^2) Bit Barrier: Scalable Byzantine Agreement with an Adaptive Adversary" by Valerie King, of the University of Victoria BC, and Jared Saia, of the University of New Mexico, recently received the best paper award at the prestigious Principles of Distributed Computing (PODC) conference. This paper describes an algorithm that solves the Byzantine agreement problem with significantly less communication than any previous results. The venerable Byzantine agreement problem addresses the question of how we can create a reliable system out of unreliable components. In particular, it requires a set of processors to come to agreement on a single bit, even when there is no trusted external party, and, moreover, a hidden fraction of the processors are controlled by an adversary.

The very word tornado is enough to scare some people, especially those who have personally experienced one of these violent storms. Others, including researchers at the University of Oklahoma, see tornadoes as a puzzle to be solved. Dr. Amy McGovern at the University of Oklahoma in Norman Oklahoma, studies tornadoes using advanced data mining techniques.

Next Generation Automatic Memory Management

Week: Sep 3 - 10, 2010
Keywords: Memory Management, Garbage Collection, Algorithms

Modern object-oriented programming languages such as Java, JavaScript, Ruby, and C# are becoming ubiquitous. A primary reason for this trend is that these languages provide automatic memory management (garbage collection), which relieves programmers of the burden of explicitly freeing memory that is no longer needed. Professor Kathryn McKinley at the University of Texas at Austin has led an NSF-funded research project, in collaboration with Steve Blackburn at the Australian National University, that is exploring how to build the software infrastructure that executes managed programs, i.e., programs in languages that provide automatic memory management. Garbage collection provides a number of software engineering benefits such as preventing common programmer memory errors that are among the most difficult to diagnose and fix. However, in the past, programs in garbage collected languages tended to be slower.

But the symbols found on many other ancient artifacts remain a mystery, including those of a people that inhabited the Indus valley on the present-day border between Pakistan and India. Some experts question whether the symbols represent a language at all, or are merely pictograms that bear no relation to the language spoken by their creators.
