The worst case analysis of rounding error of eleven numerical
quadrature formulas on a computer with floating-point arithmetic,
base b, and t digit mantissa is calculated. These results are
applied to five different integrands using the digital computer CDC
3300 located at Oregon State University. Central processing unit
computing time,...
Direct digital control is becoming quite common in the control
of industrial processes. However, due to the relatively high accuracy
of both analog and conventional digital systems for controlling the
speed of a dc motor, there has been a reluctance to try DDC for
this purpose. This thesis describes a...
This paper describes the system design of a Fortran hardware
compiler which converts the original code of a source program into
an intermediate code. This code contains features that allow easy
machine code generation. An evaluation is first made on the marketability
of such a system and then a brief...
It is necessary to evaluate and compare the characteristics of
various methods of accessing data-files in order to utilize economically
both the hardware and the software (Space and Time) supported
by the digital on-line system. The purpose of this paper is to
describe and evaluate the structure and use of...
