Echographic differentation of intraocular melanomas by computer analysis
Acta Ophthalmologica, 1992Abstract The aim of this study was to assess the differentiation of histologically different types of choroidal melanomas by means of clinical and quantitative acoustic/texture parameters of echograms. Clinical parameters were graded by morphological, kinetic and quantitative statements about the A‐ and B‐mode echograms by a skilled diagnostician ...

Computable Analysis and Differential Equations
1970Publisher Summary This chapter discusses the computable analysis and differential equations. Computable analysis is an analysis restricted to the field of computable numbers, where a real number is called computable if there is an algorithm for obtaining arbitrarily precise rational approximations.

Genders Differentials in Computer Sciences Education: Analysis and Proposal
2009 First International Workshop on Education Technology and Computer Science, 2009This article discussed the genders differentials in education, especially in computer science course education. Firstly, introduced common sexual difference, pointed out the corresponding outward performance, and the great importance should be pay more attention to.

Computer-Aided stability analysis of differential-algebraic equations
IFAC Proceedings Volumes, 2004Abstract The purpose of this paper is twofold. In the first part, a simple stability result for time-invariant nonlinear differential-algebraic equations (DAE) with higher index is derived in terms of a new Lyapunov dissipation inequality. In the second part, it is shown that this stability result can be used for a computer-aided stability analysis ...

Moment of Inertia Computation via Analysis of Differential Elements
The Physics Educator, 2020This paper explores how the analysis of differential elements and dimensional analysis can simplify the computation of the moment of inertia of certain rigid bodies by exploiting symmetries in these bodies. Integration is used scarcely, if at all, throughout this paper to emphasize the versatility of the method employed.

[Computer-aided differential thermal analysis of drugs].
Die Pharmazie, 1990An open-loop on-line computer connection to a DTA apparatus of high time constant and the developed software for data acquisition and utilization are described. The new system was calibrated thermomentrically and calorically. The main aim is a enhanced purity estimation, especially by using of the modified Van't Hoff equation based on DTA curves, which

DIF: A Computer Program for the Analysis of Differential Item Performance
Educational and Psychological Measurement, 1991A FORTRAN 77 program is presented which performs analyses of differential item performance in psychometric tests. The program performs the Mantel-Haenszel procedure and computes various additional classical indices of differential item functioning (including discrimination indices) as well as associated effect size measures.

Sparse Jacobian Computation in Automatic Differentiation by Static Program Analysis
1998A major difficulty in quickly computing Jacobians by Automatic Differentiation is to deal with the nonzero structures of sparse matrices. We propose to detect the sparsity structure of Jacobians by static program analysis. The method consists in traversing the data dependence graph extended with the control-flow of the program and computing relations ...

Computer-aided pattern analysis of temperature differentials.
Journal of manipulative and physiological therapeutics, 1990Chiropractic analysis often incorporates the evaluation of heat distribution patterns observed in skin temperature profiles. Historically, temperature recordings of the spine have been made with a heat detection instrument using a thermocouple design. The advent of refinements in infrared technology, however, have greatly enhanced temperature detection

Computation and visualisation of the accuracy of old maps using differential distortion analysis
International Journal of Geographical Information Science, 2016The accuracy of old maps can hold interesting historical information, and is therefore studied using distortion analysis methods. These methods start from a set of ground control points that are identified both on the old map and on a modern reference map or globe, and conclude with techniques that compute and visualise distortion. Such techniques have
