In order to perform intra-operative or post-implant dosimetry in prostate brachytherapy, the 3D coordinates of the implanted radioactive seeds must be determined. Film or fluoroscopy based seed reconstruction techniques use back projection of x-ray data obtained at two or three x-ray positions. These methods, however, do not perform well when some of the seed images are undetected. To overcome ...

Department of ECE, PSNA College of Engineering and Technology, Dindigul, India Email: [email protected] Abstract: Mobile Ad hoc Network (MANET) is a frequent infrastructure less selfcoordinating network, in which each and every mobile node works as a source, destination and a wireless relay. Such pattern of wireless network is produced by dynamic mob...

Trust is very important in wireless sensor networks to transfer the data from source to destination. The Dynamic Source Protocol calculates the alternate path, if any node fails to transfer the data. The Dynamic Source Protocol does not have any built-in functionality to calculate an alternate path if the path has a malicious node. With the expense of an intruder detection system we can detect ...

In a recent paper, the authors gave combinatorial formulas for Laurent expansions of super λ -lengths in marked disk, generalizing Schiffler's T -path formula. present we give an alternate expression these terms double dimer covers on snake graphs. This generalizes Musiker, Schiffler, and Williams.

In optical WDM networks, transmission of information along optical lines is advantageous since it has high transmission capacity, scalability, feasibility and also high reliability. But large amount of information is being carried; any problem during transmission can lead to severe damage to the data being carried. Hence it is essential to consider the routing as well as the wavelength assignme...

Autonomous underwater vehicles (AUVs) are robotic platforms that are commonly used to map the sea floor, for example for benthic surveys or for naval mine countermeasures (MCM) operations. AUVs create an acoustic image of the survey area, such that objects on the seabed can be identified and, in the case of MCM, mines can be found and disposed of. The common method for creating such seabed maps...
