#### Beam Propagation in Focusing Media with Random Axis Misalignments: Second-Order And Higher-Order Moments

(AIP Publishing, 1978-12-01)

A novel statistical technique which allows the asymptotic evaluation of second_ and higher_order averaged observables related to the stochastic complex parabolic equation is applied to the problem of beam propagation in a ...

#### A systematic study of the effect of casting solvent on the bulk properties of linear SBS block copolymers

(American Institute of Physics, 1978)

Using a well_characterized series of styrene_butadiene triblock copolymers, a systematic study was carried out to determine the influence of casting solvent, used for film preparation, on the final mechanical properties. ...

#### Effect of an expansion chamber on the propagation of sound in circular ducts

(American Institute of Physics, 1978-03-01)

The present analysis reveals that the performance of an expansion chamber is greatly affected by the expansion ratio, the sound frequency and to a lesser extent the chamber length. This conclusion was verified experimentally. ...

#### Natural frequencies of curved elastic arcs

(Acoustical Society of America, 1978-12-01)

A perturbation analysis is presented for calculating the inextensional natural frequencies of curved elastic arcs. Variation of the radius of curvature along the arc length is accounted for by considering the curvature to ...

#### Algebraic Specification of Complex Data Types

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1978), CS78003-R

This paper discusses algebraic data type specifications that employ product sets as carriers. This leads to simplifications for certain data types. In particular, the method permits the specification of a complex type by ...

#### Computational Experience with the Chow-yorke

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1978), CS78010-R

The Chow-Yorke algorithm is a nonsimplicial homotopy-type method for computing Brouwer fixed points that is globally convergent. It is efficient and accurate for fixed point problems. L. T. Watson, T. Y. Li, and C. Y. Wang ...

#### The Algebraic Representation of Partial Functions

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1978), CS78009-R

The paper presents a generalization of the theorem which states that any (everywhere defined) function from a finite field GF(p^n) into itself may be represented at a polynomial over GF(p^n). The generalization is to partial ...

#### Effect of Relaxation on Self-Induced Transparency

(American Physical Society, 1978-09-01)

We derive an equation of motion of the Bloch-vector tipping angle and the area theorem in the presence of relaxation. We derive relaxation-dependent shifts in the equilibrium nπ areas. Part of these shifts depends on a ...

#### Symbol Manipulation in an Interactive Environment

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1978), CS78004-R

In an interactive environment the opportunity exists for the on-line execution of an algorithm represented as a sequence of ordered commands. In particular, when the sequence of commands defines a normal Markov algorithm, ...

#### Stylitism, Synergism And Syncretism: The Interface of Computer Science And Operations Research

(Department of Computer Science, Virginia Polytechnic Institute & State University, 1978), CS78005-R

The interface of computer science and operations research is described from a stylitic perspective. This position enables an honest appraisal of the disciplinary synergism often claimed for the two. Operations research ...
