#### On Making Bairstow's Method Work

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1974), CS74003-R

No abstract available.

#### An Artificial Intelligence Approach to the Symbolic Factorization of Multivariable Polynomials

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1974), CS74019-R

A new heuristic factorization scheme that uses learning to improve the efficiency of determining the symbolic factorization of multivariable polynomials with integer coefficients and an arbitrary number of variables and ...

#### Principle of Optimal Page Replacement and the LRU Stack Model

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1974), CS74023-R

Program reference strings generated by the LRU stack model are considered, and expressions for the expected times to next reference for all pages occupying different LRU stack positions are derived. Using these expressions, ...

#### Parallel_plate waveguide with sinusoidally perturbed boundaries

(American Institute of Physics, 1974)

The method of multiple scales is used to obtain a uniformly valid asymptotic expansion for the propagation of TM modes on a parallel_plate waveguide with perfectly conducting boundary surfaces that are sinusoidally perturbed ...

#### The Role of Automatic Digitizers in Computer Aided-design

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1974), CS74026-R

The incorporation of facilities for automatically digitizing documents can considerably enhance the power of computer graphics in computer-aided-design. A hardware-software process is described which rapidly and economically ...

#### Definability of Boolean Function Over Many-value Boolean Algebra

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1974), CS74007-R

In this paper, the definability of functions over B_s is first briefly discussed. We then give necessary and sufficient conditions on the definable functions over B_2, boolean algebra of four values. An efficient algorithm ...

#### A File Definition Facility for File Structures

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1974), CS74001-R

This paper describes a file definition facility (FDF) for defining files as graph structures. The structure of the file is explicitly declared in the file definition. Primitive functions(from graph theory), operators, and ...

#### The Relationship Between the Multiplicative And Mixed Generators Modulo 2^b

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1974), CS74012-R

MacLaren and Marsaglia [4] comment that their test results suggest that the multiplicative generator performs better than the mixed generator. We attempt to answer the above question by showing that for any sequence of ...

#### Transverse vibrations of double-tapered cantilever beams with end support and with end mass

(Acoustical Society of America, 1974)

The free vibrations of a double-tapered cantilever beam with (1) end support and (2) end mass have been investigated using the Bernoulli-Euler equation. The beam was tapered linearly in the horizontal and in the vertical ...

#### Nonlinear analysis of the forced response of structural elements

(Acoustical Society of America, 1974)

A general procedure is presented for the nonlinear analysis of the forced response of structural elements to harmonic excitations. Internal resonances (i.e., modal interactions) are taken into account. All excitations are ...
