The complicated nonlinear behaviors of a triacbased controllable rectifier are investigated in this paper. The triac is modeled as a nonlinear equivalent resistor. Considering the triggering and conducting conditions of the triac and the conducting condition of the rectifier, a piecewise state space model is set up. Based on that, a discrete iteration mapping model is further developed to analyze...
In this paper, we present an improved algorithm for super-resolution image restoration which used L-Curve regularization to Maximum A-Posteriori method. Super-Resolution as the second-generation problem of image restoration is also an ill-posed question because of an insufficient number of LR images and ill-conditioned blur operators. Procedures adopted to stabilize the inversion of ill-posed problem...
The humidification–dehumidification process is an interesting technique that has been adapted for water desalination. Previous works experimentally investigated desalination processes in the shell and tube columns, where the humidification and dehumidification were thermally coupled and simultaneously performed at the tube and shell sides, respectively. In this work, a comprehensive steady-state mathematical...
