Different scramblase sequences were picked up from organisms of all eukaryotic phyla and their localization were predicted using the P-SORT programme. Our analysis showed that the scramblase protein family shows multiple subcellular localization. Most proteins were found to be localized to the cytoplasm, where as others were found to be present in the nucleus or mitochondria. Interestingly, we found that in yeast, all putative scramblases were localized in the nucleus with a reliability of more than 95%. Our analysis shows that scramblases are a family of protein having diversed cellular localization and hence hypothesized to be performing multiple cellular functions in various organisms.

We have considered a heterogeneous distributed system consists of a set of nodes(autonomous computers) with same functionality but different processing capability. This paper is aimed to find out the number of autonomous computer required to design a distributed computing platform (DCP) for a specific problem domain. The transactions initiated in any node routed to the central job scheduler (leader) for execution. The leader once elected is assumed to be fault-free during the assignment and execution of a submitted task. Scheduler model uses Dijkstra algorithm that takes half of that of Bellman-Frod algorithm for Single Origin Shortest Path problem(SOHP). Simulation are being done on a Pentium-II computer system with the model developed using Boroland C++.

The section of a parallel or distributed system spanning between the source and destination nodes is partitioned into a series of overlapping DRB groups. Each DRB group consists of three nodes: a current node and two successor nodes. Primary successor executes the primary try

These systems assist in the computing of large amounts of complicated tasks in scientific and engineering areas. It may operate in an environment where system performance features degrade due to unpredictable changes, inaccuracies in the estimation of task execution times etc. These systems need robustness. The robustness guarantees limited degradation in system performance. The following research is based on the requirement of robustness for resource allocation in grid computing environment. Four heuristic techniques for resource allocation are used to compare the robustness.

Energy efficiency is also an important design consideration due to the limited battery life of wireless node. In order to maximize the network life time and to minimize energy consumption, instead of routing through shortest path we propose routing through alternate paths. Along with that when traversing in one path, other nodes of network will be switched off in order to reduce energy consumption. For efficient sleep and active node mechanism we divide the entire network into clusters. In this paper we propose the method of using clustering along with that the probabilistic approach to find the number of active and sleep nodes at a particular time. We consider the network in terms of queuing network and consider the packets arrival rate in terms of poisson distribution.

Topology of the network is not fixed and varies dynamically with time. Routing in such an infrastructure less network is still a challenging task. In this paper we propose a novel load balanced routing for mobile ad hoc network. In this approach load is defined as the number bytes of packets transmitted by the node and the number of nodes from which it is currently receiving the data packets. Route is constructed in on demand fashion. In our approach there is a provision for handling the data collision occurred by interference by selecting the disjoint paths. For each node contributing in routing a flag bit is set with the time limit TTL once the time limit exceeds this value flag bit is reset. By this flag bit we are able to monitor the data collisions occurred due to interference of the data packets. Each node keeps track of the number of data packets transmitted by him as well as the data packets transmitted by its one hop neighboring nodes along with their flag bit status for the current time interval, by limited broadcasts of hello messages. For relaying the route request the flag bits of neighboring nodes must be at reset status. By this approach we are able to enhance the performance of DSR routing algorithm for larger extent.

Since wireless devices are usually powered by batteries.. Battery capacity is finite and the progress of battery technology is very slow, with capacity expected to make little improvement in the near future. Under these conditions, many techniques for conserving power have been proposed to increase battery life. In this dissertation we consider energy consumption cannot be achieved by routing through shortest path. By taking the shortest path energy of a small set of nodes decreases very rapidly as compare to other nodes, making the nodes to die which leads network to partition. So to maximize network life instead of using the shortest path try to use alternate path to avoid congestion. In this paper we propose one algorithm of finding alternate routes in wireless network which may decrease energy consumption by sharing the load and avoiding congested path and retransmission. I.

The simplicity and accuracy of this model facilitates for its use in many field problems, such as, infiltration computation in rainfall-runoff modelling, effluent transport in groundwater modelling studies, irrigation management studies including drainage systems etc. The numerous infiltration models based on the Green-Ampt approach have been widely investigated for their applicability in various scenarios of homogeneous soils. However, recent advances in physically based distributed rainfall-runoff modeling demands for the use of improved infiltration models for layered soils with non-uniform initial moisture conditions under varying rainfall patterns to capture the actual infiltration process that exists in nature. The difficulty that modelers are facing now-a-days includes the estimation of time of ponding and the application of the infil...

Recent research efforts to improve the reliability and accuracy of image classification have led to the introduction of the Support Vector Classification (SVC) scheme. SVC is a new generation of supervised learning method based on the principle of statistical learning theory, which is designed to decrease uncertainty in the model structure and the fitness of data. We have presented a comparative analysis of SVC with the Maximum Likelihood Classification (MLC) method, which is the most popular conventional supervised classification technique. SVC is an optimization technique in which the classification accuracy heavily relies on identifying the optimal parameters. Using a case study, we verify a method to obtain these optimal parameters such that SVC can be applied efficiently. We use multispectral and hyperspectral images to develop thematic classes of known lithologic units in order to compare the classification accuracy of both the methods. We have varied the training to testing data proportions to assess the relative robustness and the optimal training sample requirement of both the methods to achieve compa
