Concurrent multiple-scale methods can be defined as those which combine information available from distinct length and time scales into a single coherent, coupled simulation. These methods have recently become both popular and necessary for the following reasons. One is the recent discovery of new, nanoscale materials, and the corresponding boom in nanotechnology research. Another factor is tha...

sueyoshi and sekitani in 2007 presented a paper that explores the measurement of returns to scale under a possible occurrence of multiple solution in a reference set and a supporting hyperplane. the occurrence ofmultiple solutions is classified into type i and type ii. type i is an occurrence of multiple solutions in a reference set. type ii is an occurrence of multiple solutions on a supportin...

This study investigates the scheduling problem of multiple agile optical satellites with large-scale tasks. is difficult to solve owing time-dependent characteristic satellites, complex constraints, and considerable solution space. To problem, we propose a method based on an improved sine cosine algorithm task merging approach. We first establish model constraints observation action describe pr...

background and aim: multiple sclerosis is a chronic inflammatory disease of demyelinating lesions in the brain, spinal cord and optic nerve. one of the most debilitating symptoms of multiple sclerosis (ms) patients is impaired balance. thus in people with ms, collecting information about the impact of impaired balance on life style and the disability which is being perceived by the patient is e...
