Diagnostic Characteristics and Problems

1981
This chapter attempts to diagnose or analyse those features or factors which have made it possible for the developed countries to become developed and then to show that, in spite of their power, prosperity and cultural leadership, they have not been able to escape entirely serious difficulties and national problems.

Problem–Problem Solver Characteristics Affectingthe Calibration of Judgments

Organizational Behavior and Human Decision Processes, 1996
Abstract The purpose of this paper is to examine factors that affect the calibration of judgments by systematically comparing experts’ judgments to novices’ when solving a complex, real-world problem that varies in its initial characteristics. Calibration in this context refers to the proportion of times decision makers provide a range about their ...

On a characteristic Cauchy problem

Annali di Matematica Pura ed Applicata, 1987
The author considers the characteristic Cauchy problem (C) \[ u_{ts}+\sum^{n}_{j,k=1}a_{jk} u_{x_ jx_ k}+\sum^{n}_{j=1}b_ j u\quad_{x_ j}+cu=f\quad in\quad [0,T]\times {\mathbb{R}}\times {\mathbb{R}}\quad n, \] \[ u(0,s,x)=g(s,x),\quad (s,x)\in {\mathbb{R}}\times {\mathbb{R}}\quad n.

Characteristics of Problem Instances

1998
The requests on algorithms applicable in VLSI CAD differ from other areas. This also influences the design of EA based tools. For this, in this chapter some important aspects are highlighted that have to be considered.

Characteristics of Dynamic Problems

1996
Abstract There are a variety of problems where the behaviour of soils in dynamic loading is of concern, but because of diversity in the areas and complexity in the conditions under which dynamic loads are applied, it is not easy to establish a hierarchy in the discipline and to put all problems in a proper perspective.

Characteristic Modes for Aperture Problems

IEEE Transactions on Microwave Theory and Techniques, 1985
A theory of characteristic modes is developed for problems consisting of two regions coupled by an aperture. The modes are derived from a weighted eigenvalue equation whose eigenfunctions define a set of real expansion functions for the equivalent magnetic current over the aperture region and whose eigenvalues are the modal aperture admittances.

Characteristic Manifolds and the Cauchy Problem

1978
This multi-index notation is extremely convenient for partial differential equations, keeping us from drowning in a flood of subscripts. We consider here “vectors” ξ = (ξ1,...,ξ n ) with n (usually) real components and “multi-indices” α=(α1,...,α n ) which are vectors whose components are nonnegative integers.

Characteristics and Initial-Value Problems

1983
Roughly speaking, characteristics are curves which carry information. They are particularly relevant in the study of “initial-value” problems ; that is, in solving partial differential equations, in which the solution surface is required to assume prescribed values “initially.” Such a problem presupposes the existence of a distinguished coordinate, ξ ...

INTERMETALLICS: CHARACTERISTICS, PROBLEMS AND PROSPECTS

2008
Intermetallics is the short and summarizing designation for intermetallic compounds (IMCs) and phases, which result from the combination of various metals and which form a tremendously numerous and manifold class of materials. Intermetallics with outstanding physical properties led to the development of functional materials in the past. During the last

Characteristics-based modelling of flow problems: Dissertation

1994
The method of characteristics is in principle an exact way to proceed to the solution of hyperbolic partial differential equations. The numerical solutions, however, are obtained in the fixed computational grid where interpolations of values between the mesh points cause numerical errors. The Piecewise Linear Interpolation Method, PLIM, the utilization
