Abstract : The work described in the report had three objectives. First, to select a number of realistic physical problems and develop mathematical models suitable for solution on both analog and digital computers. Second, to develop successively more complete versions of one of the models to determine its suitability for solution on a hybrid computer. Third, to examine the utility of the parallel logic capabilities of an otherwise conventional modern analog computer. Some five models of problems arising from the dynamic behavior circulatory and respiratory control systems were programmed and solved on a digital computer. Three were also solved on an analog computer. A digital detection system was simulated with emphasis given to utilizing parallel logic. The most elaborate of the respiratory models considered is recommended for further investigation on a hybrid computer. (Author)
