We describe the implementation of GBTK (Grid BLAST Tool Kit), a lightweight application specific grid framework for BLAST, for geographically distributed high performance computing (HPC) systems. This framework was built on the concept of synchronized Web services using RPC (remote procedure calls) encoded as XML (extensible Markup Language).
With growing urbanization, efficient and fair distribution of water to households is critical. A typical water distribution network (WDN) consists of pipes connected by devices such as pumps, valves and tanks. The health of the network is determined by monitoring parameters such as rate of flow, pressure at a point, demand at a point. Drawing parallel with(More)
Executing clustered tasks has proven to be an efficient method to improve the computation of Scientific Workflows (SWf) on clouds. However, clustered tasks has a higher probability of suffering from failures than a single task. Therefore, fault tolerance in cloud computing is extremely essential while running large-scale scientific applications. In this(More)
Automated reconstruction and diagnosis of brain MRI images is one of the most challenging problems in medical imaging. Accurate segmentation of MRI images is a key step in contouring during radiotherapy analysis. Computed tomography (CT) and Magnetic resonance (MR) imaging are the most widely used radiographic techniques in diagnosis and treatment planning.(More)
A general framework for modeling and analyzing systems with wireless devices is proposed. This framework is used to derive an optimal state estimator when the network introduces random communication delays and packet losses. The framework is general and allows us to analyze earlier results derived in the context of state estimation with delayed and missing(More)
