Bone drilling process is one the most common processes in orthopedic surgeries and bone breakages treatment. It is also very frequent in dentistry and bone sampling operations. Bone is a complex material and the machining process itself is sensitive so bone drilling is one of the most important, common and sensitive processes in Biomedical Engineering field. Orthopedic surgeries can be improved...

Mixed-model U-shaped assembly line balancing problems (MMUALBP) is known to be NP-hard resulting in it being nearly impossible to obtain an optimal solution for practical problems with deterministic algorithms. This paper presents a new evolutionary method called combinatorial optimisation with coincidence algorithm (COIN) being applied to Type I problems of MMUALBP in a just-in-time production...

Given the problem that existing method of station distributing pseudosatellite system cannot ensure both its coverage and position in a situation signal occlusion, it proposed new stationary layout with an elite strategy for ground-based positioning based on nondominant genetic rankings (NSGA-II). The geometrical design is calculated by visual domain analysis precision factors age base station....

the performance of olive stone activated carbon (osac) for sorption of cu2+, zn2+ and ni2+ ions was investigated via batch technique. osac materials were prepared under different physially activation conditions. olive stone waste was physically activated with n2 gas and steam gas at 900oc at 3.5h hold time (osac-3) was choice as the best one for cu2+, zn2+ and ni2+ removal. characterization for...

4(4-nitrophenyl-zao)-2-(2-methoxy phenimino)-phenol and its coordination compounds with ni(ii), cu(ii), co(ii) and fe(iii) have been synthesized and characterized by elemental analyses, ft-ir, far-ir, near ir, uv-vis, mass spectrometry and molar conductivity and their electrochemical behaviours are reported.
