Developing artificial neural network (ANN), a model to make a correct prediction of required force and torque in ring rolling process is developed for the first time. Moreover, an optimal state of process for specific range of input parameters is obtained using Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) methods. Radii of main roll and mandrel, rotational speed of main roll, pr...

estimating the final price of products is of great importance. for manufacturing companies proposing a final price is only possible after the design process over. these companies propose an approximate initial price of the required products to the customers for which some of time and money is required. here using the existing data of already designed transformers and utilizing the bayesian anal...

glaucoma, a group of multifactor ocular diseases, is the second leading cause of blindness worldwide. primary open angle (poa) is the most common type of glaucoma, characterized by progressive optic nerve degeneration. numerous genes and proteins have been revealed to be associated with poag, but the pathologic mechanisms of the disease are still poorly understood. proteomics, the collective st...

Nowadays, Spatial and social inequalities are universal and expanding phenomenon. Identification and spatial analysis of social, economic and ecological inequalities in metropolises is one of the essential and basic proceeding for planning and achieving urban sustainable development. The present research method is descriptive-analytical and using 13 sub criteria based on three main criteria of ...

estimation of pure runoff is a house virtually is complex and different methods of calculation have been proposed. modern methods of solving problems in river engineering and water homes and assess the flow method is used, is that the artificial network pattern of human brain neural network training process, while implementation of the internal relationships between the data and discover for ot...

most of the multi-criteria decision methods (mcdm), including analytic hierarchy process (ahp) and analytic network process (anp), use subjective judgments for obtaining the relative importance of the decision elements of a subject matter. this has been considered as one the important limitations of the mcdms. the f’anp model, a hybrid factor analysis and analytic network process (f’anp) model ...

vermicomposting, or using worms along with bacteria and fungi to recycle agricultural and organic wastes into nutrient-rich bio-fertilizer, has a variety of uses including protecting plants from disease. through semi-structured in-person interviews, vermicompost practitioners across kermanshah province of iran were surveyed to determine the strengths, weaknesses, opportunities, and threats (swo...
