The paper is aimed to create the mathematical model of centrifugal compressor based on group method data handling-type neural networks determine volumetric flow rate as dependence compressor’s technological parameters (the rotor’s angular velocity, inlet and outlet temperatures, pressures, atmospheric pressure). It important scientific task, because most compressors used in process industry don...

Many scientific fields need to know how human systems develop. From an economic point of view, the main factors system output change are changes in quantity inputs (extensive factors) and efficiency (input quality productivity, intensive factors). The growth accounting (GA) method is used for calculation impact both on GDP change. However, its interpretation sometimes difficult, GA does not cov...

Emergency departments (EDs) have been becoming increasingly congested due to the combined impacts of growing demand, access block and increased clinical capability of the EDs. This congestion has known to have adverse impacts on the performance of the healthcare services. Attempts to overcome with this challenge have focussed largely on the demand management and the application of system wide p...
