Computer Analysis in the Differentiation of Benign and Malignant Polypoid Lesions of the Colon
Radiology, 1968Recently, Castleman and Krickstein (1), Spratt and Ackerman (7), and others have cast considerable doubt on how frequently colonic polyps become malignant. As a result, excision is no longer advised whenever a polypoid growth of the colon is discovered, and differentiation between benign and malignant polypoid growths of the colon has become a ...

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.

A Method for Computer-Aided Analysis of Differential Mode Input Filters
IEEE Transactions on Industrial Electronics, 2017A new method for computer-aided analysis of differential mode input filters is presented in this paper, aiming to compute in an efficient manner input current spectra of switching converters in a wide frequency range. The method is intended to facilitate computer-aided design of input filters, and it is based on simulation of accompanying averaged ...

Computational analysis of HRCT images for characterization and differentiation of ILD and COPD
2009 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2009Several image metrics have been proposed for pulmonary assessment via thoracic high-resolution computed tomography (HRCT) for various pathologies. This paper describes a systematic analysis of several such metrics for differentiating between interstitial lung disease (ILD) and chronic obstructive pulmonary disease (COPD).

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 ...

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.

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.

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 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 ...
