Typically, NC programmers generate tool paths for end milling using a computer-aided process planner but manually schedule “conservative” cutting conditions. In this paper, a new evolutionary computation technique, particle swarm optimization (PSO), is proposed and implemented to efficiently and robustly optimize multiple machining parameters simultaneously for the case of milling. An artificia...

Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel. 3-D model of the Lower Wishbone Arm is prepared by using CAD software for modal and stress analysis. The forces and moments are used as the boundary conditions for finite element model of the wishbone arm. By using these boundary conditions static analysis is carried out. Then m...

introduction: the need for food produced from animal husbandry has made it a growing industry which result in increment of livestock waste. on the basis of environmental and economic considerations, these materials require treatment and management. anaerobic digestion and creation of biogas are the most effective methods of waste management. several parameters affect the anaerobic digestion of ...

results the optimal conditions were considered to perform elisa. comparison between results obtained from optimized elisa kit and commercial elisa kit showed a good agreement. background haemophilus influenzae type b (hib) infection has high morbidity and mortality rate, especially in children under 5 years of age. enzyme-linked immunosorbent assay (elisa) technique is the most used method to d...

One of the major steps toward the industrialization of the microbial product(s) is to optimize the cultivation conditions at the large-scale bioreactor and successfully control the microbial behavior within a large scale production environment. Statistical Design of Experiment was proven to optimize a vast number of microbial processes to achieve robustness and explore possible interactions...

primary vision care is recommended for infants and young children .childhood is critical time to prevent loss of vision and to optimize treatment so some eye disorders in children must be diagnosed at this time.to detect risk factors and visual abnormalities, the eye screening done by pediatricians and other primary care providers is necessary. the process that should occur at each child visit ...

The aim of this study was to optimize the extraction conditions for the extraction of phenolic compounds from Moringa oleifera leaves using response surface methodology (RSM). A user-defined design was applied to determine the effects of extraction time (min), extraction temperature ((o)C) and ethanol concentration (%), on total phenolic content (TPC) from Moringa oleifera leaves dried by three...

The aim of this paper is to investigate and optimize surface quality and geometrical characteristics in drilling process of AISI H13 steel, because they are critical items for precision manufacturing. After conducting the experiments, two regression models are developed to extensively evaluate the effect of drilling parameters on process outputs. After that, evolutionary multi-objective optimiz...
