A method developed for the analog computer using minimization to find a quadratic factor of a polynomial is extended to include a deflation process, so that all the quadratic factors can be determined simultaneously.

After a brief review and classification of the known generators, this part I of 2 parts paper investigates carefully a new programmable generator of general ordinary renewal processes in discrete time. The generator is based on the concept of failure rate and its implementation is completely...

Instead of integrating with respect to time, some of the integrators become accumulators for space variables. The input to these integrators is switched at regular intervals to finite increments, which are meanwhile computed in analogue fashion from known differential equations, their boundary...

In this paper a comprehensive theoretical basis is formulated concerning the hybrid computer approximation of partial differential operators. The investigation leads to a theorem that enables the identification of consistency and error properties of general hybrid methods. The theorem is applied...

Queueing models are important in the analysis of many aspects of system or human behaviour. In such widely divergent fields as administrative processes, health services, traffic control, production control, computer communication networks, time sharing, and architecture, queueing analysis is...

In a hybrid-code differential analyzer system, variables and parameters are represented by the combination of a coarse n-bit number and a continuously variable analog interpolation voltage. The hybrid-code system combines analog elements accurate to within p per cent of half-scale with the n-bit...

A development of Berman's method is described for computing the input of a known system given its output. The method is not restricted to linear systems and allows the state equations to be used in the normal manner, only the output equation or some derivative of it needing to be used in an...

Spectral procedures that have been developed to estimate the variance of the sample mean of simulation output are presented and evaluated. The evaluation is performed using a single server queueing situation with exponential interarrival and service times. This process is employed because...

The APE II computer system is a small solid-state iterative differential analyser designed for laboratory instruction and is capable of both repetitive and real-time operation. This paper describes the APE II digital module, which includes a master clock for generating reset and sampling pulses,...
