Conversion Disorder Formerly known as "Hysteria‚" and also called Pseudoneurologic Syndrome‚ Hyterical Neurosis‚ or Psychogenic Disorder‚ Conversion Disorder is a type of Somatoform disorder. Symptoms occur that commonly resemble those of neurological disorders such as stroke‚ multiple sclerosis or epilepsy‚ but seemingly happen without corresponding bodily damage‚ and there are no existing physical disorders. Medical tests on people that have this disorder are either normal or they are unable

Neural Network For Optimization An artificial neural network is an information or signal processing system composed of a large number of simple processing elements‚ called artificial neurons or simply nodes‚ which are interconnected by direct links called connections and which cooperate to perform parallel distributed processing in order to solve a desired computational task. The potential benefits of neural networks extend beyond the high computation rates provided by massive parallelism. The neural

Running Head: Energy Conversion Energy Conversion Marlon Walker Professor Abdul Kahn SCI 110: Integrated Science October 21‚ 2011 Abstract Energy conversion has been a topic of debate and research for many years. Scientists conduct experiments in hopes of finding an alternative to relying on burning fossil fuels for electricity. While companies who believe their alternative is the best choice‚ debate over whose source is the “greenest”. Whether it be biomass‚ hydroelectricity‚ solar
