Development of genetic algorithm toolbox using MATLAB in cutting tool path optimization

  In this study, optimization of tool path is presented through simulation material removal using Finite Element Analysis (FEA) and control via Genetic Algorithm (GA). The computer code for GA is developed and is specifically designed using MATLAB programming. The developed GA toolbox was written in m-files script together with several built-in functions in order to import the text file generated by FEA...

Modeling the performance of upflow anaerobic filter (UAF) reactors treating paper-mill wastewater using neural networks

  This study investigated the predictive ability of neural networks in the estimation of methane yield (MY) and effluent substrate (Se as mg/L COD) produced by two anaerobic filters, one mesophilic (35°C) and one thermophilic (55°C), which were operated to treat paper-mill wastewater at varying organic loadings. An artificial neural network (ANN) architecture was optimized to obtain a three-layer neural...

Environmental challenges of Millennium Development Goals (MDGs) 4, 5 and 6: The roles of midwives in Nigeria

    With less than five years to the 2015 target set by the United Nations for the achievement of the Millennium Development Goals (MDGs), MDGs 4, 5 and 6 are still far from being achieved. Nigeria has the second highest maternal mortality and eighteenth highest child mortality in the world. Efforts to combat HIV and other diseases have recorded only marginal success. This paper identified...

Study on the health-related quality of life after surgical treatment for lumbar stenosis

  Lumbar stenosis (LS) affected middle-aged people and may cause severe symptoms and functional impairment at lower limbs. We conducted a study in China to assess the HRQoL in patients operated on for LS, and investigate the possible determinants of HRQoL. From June 2008 to June 2010, 60 patients have been surgically treated for lunbar stenosis in our Hospital. The medical outcomes study short Form 36 (SF-36)...
