This paper discusses the development of simultaneous optimization model to determine component tolerance of assembly product and plant for manufacturing processes by considering quality tolerance limits, and delivery time constraint to minimize total cost in collaboration environment of make-to-order manufacturing systems.Total cost of the system c
Nutritional iron deficiency anemia is considered the main public health problem of poor less-developed and developing countries.The World Health Organization has estimated that 1.5-2.0 billion persons are anemic.It Bar Soap has been said that close to 1 million deaths are linked to iron deficiency anemia.The groups most vulnerable to this form of a
In view of the problem that Bloch Quantum Genetic Betaine HCL (TMG) Algorithm (BQGA) is easy to fall into local optimum, an improved BQGA is proposed.The algorithm can control the step size and the mutation probability in real time in the iterative process, avoiding over the optimal solution and guaranteeing search efficiency.In addition, the impro
Background: Arachnoid cysts are cerebrospinal fluid (CSF) fluid-filled sacs that are located between the brain and spinal cord.Spinal column arachnoid cysts are rare and mostly asymptomatic, being mostly located in intradural regions.We reported a patient who presented with neurological deficits and mid-thoracic extradural arachnoid cyst treated wi
