Clusters of SMPs (Symmetric Mul-tiprocessor Systems) have emerged as important platforms for high performance computing. As a programming scheme on SMP clusters, we proposed hybrid shared memory/distributed memory programming. In order to tolerate inter-node communication , we overlapped the inter-node communication and computation using remote memory based user-level communication primitives N...

In sensor network the node connectivity is to be changes of disruption in wireless communication, transmission power changes or loss of synchronization between neighbour nodes. Hence a sensor is aware of its immediate neighbour it must continuously maintain of its view. It’s called continuous neighbour discovery. In this paper it differentiates between neighbour discovery during sensor network ...

Uterus, bladder and rectum are the maximally exposed organs during cervical cancer radiotherapy and are at high risk of radiation exposure. Estimation of dose accumulation in these organs across multiple fractions of external beam radiotherapy (EBRT) and brachytherapy (BT) is extremely challenging due to structural mis-correspondences and complex anatomical deformations between the EBRT and BT ...

We present a detailed theoretical analysis of the properties and formation of single solitons and higher-order bound dipole pairs in media with anisotropic nonlocal photorefractive material response. The single solitons are elliptical beams, whereas the dipole pairs are formed by a pair of displaced elliptical beams with a p phase shift between their fields. The theory predicts convergence of G...

We present our current work-in-progress on the design and implementation of a hybrid TDMA/CSMA medium access architecture, hereafter referred to as hMAC, which can be used on top of commercial IEEE 802.11 off-the-shelf hardware. The software only solution is based on the popular Linux ATH9K softMAC driver and hence can be used with standard Linux systems using Atheros based wireless network dev...

We propose a node-removal/arc-reversal algorithm for influence diagram evaluation that includes reductions that allow an influence diagram to be solved by a generalization of the dynamic programming approach to solving partially observable Markov decision processes (POMDPs). Among its potential advantages, the algorithm allows a more flexible ordering of node removals, and a POMDPinspired appro...

In this study, activated sludge process for wastewater treatment in a refinery was investigated. For such purpose, a laboratory scale rig was built. The effect of several parameters such as temperature, residence time, effect of Leca (filling-in percentage of the reactor by Leca) and UV radiation on COD removal efficiency were experimentally examined. Maximum COD removal efficiency was obtained...

In this work lexical choice in generation for Machine Translation is explored using lexical semantics. We address this problem by replacing lemmas with synonyms in the abstract representations that are used as input for generation, given a WordNet synset. In order to find the correct lemma for each node we propose to map dependency trees to Hidden Markov Trees that describe the probability of a...

Vehicular AdHoc Networks or VANETs are emerging as a promising technology for providing safety and comfort applications for vehicular transportation. VANETs are receiving growing attention from the research community and from the transportation industry because of their great potential to improve traffic safety on roads. In existing system the IEEE 802.11 broadcasting mode, considers no request...

Clinicians are trained to manipulate a colonoscope while minimizing the force exerted on the colon walls to reduce the danger of luminal perforation and discomfort to the patient. Here, we classify the expertise of the clinician performing colonoscopy using a Hidden Markov Model. Seven models are trained corresponding to the performance of the expert in the entire colon, ascending, transverse a...
