A BASIC program to calculate intraocular lens power and refractive errors using previously derived equations is presented. The program was written for the IBM PC and PCjr computers with an emphasis on clinical usefulness. program features include a comparison of refractive and axial length predictions of secondary implant power and velocity compensation for axial length measurements made on aphakic patients. Equation specification by input variable selection and automatic averaging of keratometer readings make the program highly efficient.

This thesis gives the user of an H?-'4 1CV handheld program- mable calculator or the IBM 3033 computer, acceptable results of heliccpter system weight estimations during the preliminary design phase. The computer program consists of several subroutines and will compute system weighs estimates according to Military Standard 137UA. Three categories of military helicopters can be designed; observation, utility, and cargo. Detailed knowledge of helicopters is not. required.

A computer program for the analysis of drug pharmacokinetics is described. The program is written in BASIC for use with a Hewlett Packard HP85 microcomputer. The pharmacokinetic parameters are estimated by linear regression of the log concentrations against time and the exponentials are separated by curve stripping.

A computer program which enables detection of segmental abnormalities of the left ventricular contraction was developed using the principles of Leighton et al. [Circulation 50 (1974) 121–127]. A film projector, a digitizer a graphic display and a mini-computer are used. The end-diastolic (ED) and end-systolic (ES) left ventricular silhouettes are traced from 30° right anterior oblique cineangiograms projected on a screen of the film projector. The program determines semi-automatically both apexes and longitudinal axes of the left ventricle. Lines [( N − 1) ≤ 60] are drawn perpendicular to longitudinal axes, dividing longitudinal axes into equal N segments, respectively. These perpendicular lines are extended to intersect ED and ES silhouettes at 2( N − 1) points, respectively. The distances along each of 2( N − 1) hemiaxes are defined as short axes [S-ED i and S-ES i , i = 1 ∼ 2( N − 1)]. Segmental wall contractions are expressed as a percentage of the distance from S-ED i to S-ED i , and displayed as a graph with normal values (mean ± 2 SD). The presence and extent of segmental contraction abnormalities can be evaluated quantitatively by observing a percentage of segmental wall contractions. This program greatly facilitates a correct diagnosis in clinical use.

A computer program (written in FORTRAN) is presented which uses Monte Carlo techniques to simulate one-searcher, one-target passive acoustic ASW search that terminates at detection. A threshold crossing detection model is used, and stochastic variations in the acoustic signal are modeled using either a Lambda-Sigma Jump or Gauss-Markov error process. Both platforms have the capability of detecting each other, and area and barrier searches are modeled. Features of the program include interactive data input, extensive use of graphical displays, and thorough statis- tical analysis of the results of the simulation.

The geometrical analysis leading to equations which permit the interactive construction of general stereographic projections by means of a computer program compatible with modern microcomputers is given. The stereographic operations covered include the plotting of any pole or direction on a projection of any orientation, and the drawing of the great circle of the plane which is normal to this plane or direction. Other operations considered here are the indexing of any pole at locationx, y, the rotation of any one general pole about another, and the direct transfer of diffraction spots on a backreflection Laüe pattern to the stereographic projection using only thex, y coordinates of the Laüe spots. All of the above operations may be performed in any crystal system since simple equations are included for the calculation of the indices of a Cartesian vector normal to any (h k l) plane or parallel to any [u v w] direction in a general crystal. A description of a microcomputer program utilizing the expressions derived is given together with a few examples of graphical output from the program.

The linearization approach is used to compute the travel times in inhomogeneous slightly anisotropic media. The basic formulae are outlined and their accuracy demonstrated in comparison with the exact solution based on the zero-order ray theory and the Backus formula (1965). The linearization is extended also to complex media with curved interfaces. The computer program for calculating travel times in 2D, inhomogeneous, slightly anisotropic, complex media is briefly described. The numerical results obtained for a realistic situation and various types of waves are presented to enable the effects of anisotropy and the effects of inhomogeneity on the resulting travel times to be compared.
