The aim of the project develop novel method for optimization of silicon power device parameters using lifetime killing techniques based on high energy particle irradiation. We investigated the effect of sloping lifetime reduction in the power chip P-iN diode using 500 keV electron and high energy proton irradiation and compared it with local lifetime killing by high energy alphas. The device un...

In this paper, the authors have proposed Fuzzy Cost Metric based Adaptive (FCMA) routing protocols for WSNs. Residual energy, Congestion level and Connectivity parameters have been used to calculate the fuzzy routing cost in order to decide the forwarding node. The results obtained indicate that the proposed FCMA protocols reduce the energy consumption and latency and increase the lifetime of t...

Low delay and long lifetime are a very important issue for industrial wireless sensor networks (IWSNs) in which it require long-time monitoring of industrial sites and respond quickly to events that is monitored; therefore, high delay communications can cause serious damage to property and personnel at industrial field. Due to delay, lifetime, and other performance involved to multiple layers, ...

Wireless sensor networks (WSNs) are being envisioned for certain applications like habitat monitoring and environmental sensing. Wireless sensors are deployed to achieve network load balancing, prolonging network lifetime, and improving network coverage. To achieve these goals, energy estimation is one of the main constraints and concerns to consider, while deploying wireless sensors in a WSN f...

We present algorithms to solve relativistic hydrodynamics in 3+1–dimensional situations without apparent symmetry to simplify the solution. In simulations of heavy–ion collisions, these numerical schemes have to deal with the physical vacuum and with equations of state with a first order phase transition between hadron matter and a quark–gluon plasma. We investigate their performance for the on...

Complex structural effects in the nuclide production from the projectile fragmentation of 1 A GeV U nuclei in a titanium target are reported. The structure seems to be insensitive to the excitation energy induced in the reaction. This is in contrast to the prominent structural features found in nuclear fission and in transfer reactions, which gradually disappear with increasing excitation energ...

target coverage is one of the important problems in visual sensor networks. the coverage should be accompanied with an efficient use of energy in order to increase the network lifetime. in this paper, we address the maximum lifetime for visual sensor networks (mlv) problem by maximizing the network lifetime while covering all the targets. for this purpose, we develop a simulated annealing (sa) ...

in this paper, an algorithm , based on genetics and auxiliary nodes, to reduce energy consumption in wireless sensor networks has been presented. in this research, by considering some parameters as energy and distance, a target function has been created, which is more optimum comparing to other methods. in this research cluster head is selected by genetic algorithm. in rawsn algorithm a new tec...

The attitudes toward the use of nuclear energy of three student samples of roughly equal size (N=lSO) from FR Germany, Japan and the Philippines were elicited and compared by means of a questionnaire. Concerning their overall attitudinal positions the Japanese students were predominantly in favour of nuclear energy, the German students were less unanimous while the Philippine students showed th...
