Although acromioclavicular joint separations are fairly common, the occurrence of high-grade acromioclavicular separations that require surgery is low. Various modifications of the Weaver-Dunn procedure have been popular and fairly successful methods to treat severe acromioclavicular separations, despite the fact that reconstructions have been done a number of ways. We report on the results of ...

Long ago, since 1951, Lyra proposed a modification of Riemannian geometry. Based on the Lyra's modification on Riemannian geometry, Sen and Dunn constructed a field equation which is analogous to Einstein's field equations. Further more, Sen and Dunn gave series type solution to the static vacuum field equations. Retaining only a few terms, we have shown that their solutions correspond to black...

Segmentation of digital image plays a major role in computer visualization. It is used to extract meaningful objects that exist on the images. Region based clustering is done to extract objects based on the colors present in the satellite images. The principle of clustering is to identify the similar domains from a huge data set to produce an accurate representation of the image. In this paper,...
