This paper analyzes various schemes for the Euler-Poisson-Boltzmann (EPB) model of plasma physics. This model consists of the pressureless gas dynamics equations coupled with the Poisson equation and where the Boltzmann relation relates the potential to the electron density. If the quasi-neutral assumption is made, the Poisson equation is replaced by the constraint of zero local charge and the ...

In a balanced three phase system, only harmonics of positive sequence(7 th , 13 th ,..etc) and negative sequence (5 th , 11 th ,…etc) are produced. However, the harmonic currents produced by single phase non-linear loads like switch-mode power supplies in computer which are connected between phase to neutral injects third order zero sequence harmonics (3 rd ,9 th ,15 th …etc) (Mehmet et al 2008...

OBJECTIVE To evaluate the perception of facilitators and students on the implementation of PBL, based on their experience. METHOD A questionnaire based survey was conducted on 186 first and second year students and 25 faculty members. RESULT The responses of faculty members and students were analyzed using Chi-square and a P-value < 0.05 was considered significant. Comparison between facult...

Research on retrieval suppression has produced varying results concerning whether negatively valenced memories are more or less suppressible than neutral memories. This variability may arise if, across studies, participants adopt different approaches to memory control. Cognitive and neurobiological research points to two mechanisms that achieve retrieval suppression: thought-substitution and di...

This paper proves that a simultaneously delta-neutral and gamma-neutral position can be established with the underlying asset and two options on the same asset, without any assumption on the underlying process of the asset price. This hedging strategy leads to the same fundamental partial differential equation as derived by Black and Scholes (1973), except that the variance function is the mark...

Due to non-homogeneous spread of sunlight, sensing nodes possess non-uniform energy budget in rechargeable Wireless Sensor Networks (WSNs). An energy-aware workload distribution strategy is therefore necessary to achieve good data accuracy subject to energy-neutral operation. Our previously proposed Energy Aware Sparse approximation Technique (EAST) can approximate a signal, by adapting sensor ...
