Some commonly unrecognized manifestations of metabolic arthropathies

The metabolic arthropathies are characterized by the deposition of abnormal substances in or around joints. Certain features of some of these arthropathies and their significance have only recently been recognized and others have been insufficiently emphasized. An important group of conditions are the arthropathies related to renal failure and its treatment, namely, aluminum toxicity, periarticular calcification and crystal deposition, hyperparathyroidism, and dialysis-related amyloidosis. Crystal deposition diseases, specifically, gouty arthritis, calcium pyrophosphate deposition, and calcium hydroxyapatite deposition, are also reviewed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/30253/1/0000648.pd

Real time edge detection using three dimensional systolic array

Real time video processing is gaining importance, while the size of the video sequences are also getting larger with the improvement of new multimedia applications. Eventhough software based video and image processing systems have significant advantages like flexibility and cost effectivity, they are lacking performance, which makes hardware based systems more preferable for real time high definition applications. This paper presents a row wide edge detection algorithm based on a three dimensional systolic array structure. The row wide approach improves the performance of the algorithm when compared with the pixel wide algorithms presented in previous works. The presented results show significant improvement in processing time.</p

Toward futuristic near-natural collaborations on Distributed Multimedia Plays architecture

This paper presents a vision of how people can collaborate in real-time in the future from different places on the continents with near-natural quality of experience. To achieve that very high quality, the requirements are also very high and challenging. The ultimate challenge for its implementation is to guarantee end-to-end delay less than 10-20 ms with graceful quality variability to enable live musical collaborations. The Distributed Multimedia Plays architecture with the AppTraNet protocol and the design of the collaboration spaces is our proposal for the realization of the vision, since existing Internet standards are unable to provide such guarantee. The relation of this novel proposal to the existing and future standards is also discussed. It is expected that significant milestones on this research avenue will be attainable in the next 5-10 years.</p

Parallel image transmission and compression using windowed kriging interpolation

We propose the use of windowed kriging to enable ordinary kriging to interpolate sampled natural images of much higher resolution. Due to its high computational cost, applying ordinary kriging on a whole image can interpolate samples from only 5% of a 64×64 image, while windowed kriging can process images with resolutions higher than 512×512 pixels. Our proposal is motivated by our vision of real-time near-natural collaboration from distributed places based on Distributed Multimedia Plays (DMP) architecture that is realizable in another decade. Windowed kriging allows parallel transmission and compression of sampled natural images to facilitate controlled packets dropping by network nodes for graceful video quality degradation with guaranteed maximum end-to-end delay. Our simple window scheme makes parallel interpolation at the receiver side possible, for which a design of parallel hardware implementation is presented. Typical artifacts due to applying the technique can easily be eliminated completely to produce images of decent quality.</div
