Particle-in-cell Monte Carlo simulation using free path method for radio frequency argon discharge modelling: Comparison with experiment

  A specific particle-in-cell Monte Carlo model which is based on an optimized free path method for collision treatment has been used to simulate a radiofrequency (RF) argon discharge at low pressure for parallel-plate geometry. In this model, the free path determination is independent of the electron energy; it depends only on the maximum of the total cross sections. The obtained results are in excellent...

Estimation of global solar radiation on horizontal surface in Erzincan, Turkey

  In the applications of solar energy, the solar radiation data and their components in a region must be known for the design of a system. In the locations where no solar radiation data is available, this parameter can be determined by performing a reasonable correlation. In the study, the models of global solar radiation on the horizontal surface in the literature are investigated, and new empirical models...

Effects of different combinations of Hoagland’s solution and Azolla filiculoides on growth and development of Beta vulgaris subsp. cycla ‘Fordhook Giant’ grown in hydroponic cultures

  The comparisons of plant height, leaf number, foliage colour, fresh and dry weight of Beta vulgaris subsp. cycla ‘Fordhook Giant’ were evaluated in the glasshouse over a period of 8 week. The B. vulgaris plants were exposed to different nutrient solutions in which some contained Azolla filiculoides. Each treatment was replicated four times. The aim of this study...

Multipath adaptive tabu search: Its convergence and application to identification problem

  This article presents new metaheuristics denoted as multipath adaptive tabu search (MATS). The algorithms employ adaptive tabu search (ATS) as the main search heuristics, and incorporate partitioning, sequencing, and discarding mechanisms, respectively. The algorithms are explained in details with their convergence analyses presented. The article also gives an illustrative application of...
