background: to correct patient positioning errors (setup errors) during prostate cancer treatment using epid and fiducial gold markers, to improve the accuracy of the dose delivery in these patients. materials and methods: fifteen patients with localized prostate carcinoma after implantation of fiducial gold markers in their prostate gland underwent the five-field imrt planning technique. the p...

From a global perspective, dams are constructed to trap water flowing from higher concentration lower into basin for several purposes aid humanity. The continuous monitoring of is prudent measuring the rate sedimentation and siltation, ensure that it functions its full capacity. Tagwai dam used irrigation domestic activities. It was observed there shortage in storage capacity supplies due sedim...

In this paper we treat design philosophies and enabling technologies for ambient awareness within grids of future mobile computing/communication devices. We extensively describe the possible context sensors, their required accuracies, their use in mobile services—possibly leading to background interactions of user devices—as well as a draft of their integration into an ambient aware device. We ...

SAR interferometric data can be used for extracting three dimensional information of the earth’s surface by using the phase part of the radar signal. In this study, available SAR interferometric data acquired before and after the Marmara earthquake of 1999 and provided by ESA were used for mapping the ground deformation in the satellite line of sight (LOS) in the Izmit province. The interferome...

This paper provides an overview of the Naval Postgraduate School ARIES autonomous underwater vehicle and its control and navigation performance. An attempt is made to highlight its current operational capabilities and provide a description of future enhancements for greater mission utility and flexibility. An overview of the vehicle design along with descriptions of all major hardware component...
