A computational method for weighted euclidean distance scaling (a method of multidimensional scaling) which combines aspects of an "analytic" solution with an approach using loss functions is presented. (Author/JKS)

The purpose of this study was to evaluate the parallel processing impact of multiple-instruction multiple-data path (MIMD) computers on flight simulation software. Basic mathematical functions and arithmetic expressions from typical flight simulation software were selected and run on an MIMD computer to evaluate the improvement in execution time…

In mastery testing, the raw agreement index and the kappa index may be estimated via one test administration when the test scores follow beta-binomial distributions. This paper reports formulae, tables, and a computer program which facilitate the computation of the standard errors of the estimates. (Author/CTM)

The density and Monte Carlo methods for approximating the area under a curve, without relying on calculus, are given. A computer program is included. (MNS)

The RKR method for determining accurate potential energy curves is described. Advantages of using the method (compared to Morse procedure) and a TRS-80 computer program which calculates the classical turning points by an RKR method are also described. The computer program is available from the author upon request. (Author/JN)

A Monte Carlo simulation was employed to determine the accuracy with which the shrinkage in R squared can be estimated by five different shrinkage formulas. The study dealt with the use of shrinkage formulas for various sample sizes, different R squared values, and different degrees of multicollinearity. (Author/JKS)

"TK!Solver" was designed as a personal computing tool to solve problems involving mathematical calculations and analysis. An in-depth review of this model building and problem-solving package is provided. System commands, applications (including data lists, plots/graphs, iterative problem-solving, present values), and other areas are…

Describes advanced undergraduate laboratory exercise examining the dependence of the rate constants and the instantaneous concentrations with the nature and energy content in a gas-phase complex reaction. Computer program (with instructions and computation flow charts) used with the exercise is available from the author. (Author/JN)

Some insights are provided into techniques for removing the mystery of how calculators evaluate functions. (Author/MK)

The ratings of 43 third-year medical students were used to investigate a method of computing the reliability of ratings. The students were evaluated on a four-point rating scale along seven dimensions of clinical ability: diagnostic ability; motivation; sense of responsibility; oral-verbal ability; effectiveness with patients; ability to take a…

Designed as a tool for colleges and the State Board for Community Colleges in Maryland to update economic impact data on a regular basis, this manual describes sources of impact information, and how the information can be used in economic equations. Part I of the manual describes how values for short-term economic impacts of community college…
