The various multipath routing wireless sensor networks uses multipath routing to answer user queries in the presence of defective and malicious nodes. The fixed method uses a novel probability model to analyze the best redundancy level in terms of path redundancy (mp) and source redundancy (ms), as well as the best interruption detection settings in terms of the number of voters (m) under which...
Fault tolerance techniques have been traditionally used for specific applications such as space, avionic, or nuclear where the reliability is of utmost importance. Moreover, nowadays the reliability of nanoscale CMOS processes is reduced, and the power optimization goes beyond the standard worst-case boundaries. As a consequence, fault tolerance became the important factor also for the main str...
A methodology to evaluate force capabilities of planar parallel manipulators is presented in this paper. Different from previous approach, kinematic redundancies are handled and proper used to improve force capabilities. Add to actuators wrench parameters normally present in a force optimization problem, kinematic redundancy introduces geometric parameters to be optimized, producing non-linear ...
This paper has been worked on a RAP with multi-state components and the performance rate of each component working state may increase by spending technical and organizational activities costs. Whereas RAP belongs to Np-Hard problems, we used Genetic algorithm (GA) and simulated annealing (SA) and for solving the presented problem and calculating system reliability universal generating function ...
Source coding, also known as data compression, is an area of information theory that deals with the design and performance evaluation of optimal codes for data compression. In 1952 Hu man constructed his optimal code that minimizes the average code length among all pre x codes for known sources. Actually, Hu man codes minimizes the average redundancy de ned as the di erence between the code len...
OBJECT/RELATIONAL QUERY OPTIMIZATION WITH CHASE AND BACKCHASE Lucian Popa Supervisor: Val Tannen Traditionally, query optimizers assume a direct mapping from the logical entities modeling the data (e.g. relations) and the physical entities storing the data (e.g. indexes), each physical entity corresponding precisely to one logical entity. This assumption is no longer true in non-traditional app...
