In this paper, we propose a new envelope-following parallel transient analysis method for the general switching power converters. The new method first exploits the parallelisim in the envelope-following method and parallelize the Newton update solving part, which is the most computational expensive, in GPU platforms to boost the simulation performance. To further speed up the iterative GMRES solving...
Gas pipe flow simulation is used to optimize, verify design and to throw light on various operational issues. This paper illustrates some of the different parameters affecting how complicated it is to do those computations, arranged so that the simplest alternatives are on top.
In the present study we reported the feasibility of extracellular biopolymer (PF-9) produced by Pseudomonas fluorescence C-9 as an alternative biosorbent to remove Pb(II) metallic ions from environmental and industrial wastewater.The ability of PF-9 to remove the metallic ions was investigated by using batch biosorption procedure. The effects such as, pH, biosorbent dosage, sorbate concentrations...
An extracellular biopolymer (PS-2) produced by Pseudomonas fluorescence C-2 was used as an alternative biosorbent to remove toxic Pb(II) metallic ions from aqueous solutions. The prepared biosorbent PS-2 were characterized by FTIR and SEM. The effect of experimental parameters such as pH, dosage of biosorbent , Pb(II) initial concentration and contact time on the adsorption was studied. It was found...
Panorama imaging camera, as an effective tool, has been applied widely to geological prospecting. But there exist distortions in imaging the geological object, especially prospecting excavation, owing to the shortcoming of lens. In addition, the traditional correction methods are too complex to obtain the actual applications. This paper proposes a correction method based on straight baseline, which...
Model order reduction by truncated balanced realization (TBR) is better than Krylov subspace methods to achieve smaller models with global error control. TBR projects a system onto the dominant invariant subspace in terms of both controllability and observability measured by their gramians. However, to obtain two gramians, two Lyapunov equations have to be solved and its high computation costs involved...
In this paper, we introduce a novel temperature compensated crystal oscillator - analog memory compensated crystal oscillator (AMCXO), a microcomputer compensated crystal oscillator (MCXO) based on an analogue approach, and we compare the performance between MCXO and AMCXO, arid analyze the necessity of developing AMCXO. Both AMCXO and MCXO, combined with their test systems, use computers to generate...
