In this study the correlation between lag factor G and Page ́s mathematical model parameter n was developed. Using the newly developed correlation the presence of internal or external resistance to moisture transfer during thermal drying can be verified. As modeling tools Artificial neural networks (ANN) and Adaptive neuro-fuzzy inference system (ANFIS) were used. The best model for determinatio...
there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
In the present study, the wintering birds of the artificial wetlands of Yazd province in 1393, 1395 and 1396 were studied. This study is one of the first studies conducted with the aim of preventing the drying process of the wetland by emphasizing on maintaining water rights and protection of migratory birds in the artificial wetland of Yazd. Data from winter and autumn counts which were carrie...
BACKGROUND The current typical drying methods for red ginseng are sun drying and hot-air drying. The purpose of this study was to investigate drying characteristics of red ginseng by using far-infrared drying. METHODS The far-infrared drying tests on red ginseng were conducted at two drying stages: (1) high temperature for 24 h drying and (2) low temperature drying until the final moisture co...
Abstract This study reports results on the estimated magnitude of changes in P sorption isotherms clayey mud sediments when performed using (1) freeze-dried instead fresh sediment samples and (2) artificial sea water (ASW) ambient near-bottom water. The used differed their sorption. For isotherms, were equilibrated for 48 h solutions varying concentration whereafter amount sorbed or desorbed wa...
BACKGROUND Modelling moisture diffusivity of pomegranate cultivars is considered to be a major aspect of the drying process optimization. Its goal is mainly to apply the optimum drying method and conditions in which the final product meets the required standards. Temperature is the major parameter which affects the moisture diffusivity. This parameter is not equal for different cultivars of pom...
