Abstract Intravascular ultrasound (IVUS) imaging is a diagnostic imaging technique for tomographic visualization of coronary arteries and studying atherosclerotic diseases. These medical images are generally corrupted by multiplicative speckle noise due to the interference of the signal with the backscattered echoes. Speckle noise is an inherent property of medical ultrasound imaging, and it generally tends … Read more

Recommender systems are information filtering tools which aim to predict the rating or preference that a user would give to an item. They are important especially with the explosive growth of data. As such, recommender systems are created to act as information filtering systems. They are a useful alternative to search algorithms and help a … Read more

Modern operating systems should be extensible and flexible. This means that the operating system should be able to accept new behavior and change existing behavior without too much trouble and that it should ideally also be able to do this without any, or very little, downtime. Furthermore, during the past years the importance of the … Read more

Abstract: The WiMax network is to provide the users with access to the info of interest from data gathered by spatially distributed sensors. Generally the employers require only assured aggregate functions of this dispersed data. Computation of this collective data under the end-to-end evidence flow paradigm by interactive all the relevant data to a middle … Read more
