ON THE DEGENERATE CENTER PROBLEM

International Journal of Bifurcation and Chaos, 2011
In this work, it is proved that any degenerate center is limit of a [Formula: see text] linear type center and when the degenerate center has an analytic first integral then it is limit of an analytic linear type center. A new method to detect integrability developed in [Giné & Santallusia, 2011] is applied to the degenerate center problem ...

Continuous Center Problems

2011
The minimax facility location problem (also called the one center problem) seeks to locate a facility so that the maximum distance to a set of demand points is minimized. Using Euclidean distances in the plane, this problem is equivalent to finding the center of the smallest circle enclosing all points, hence the term “center” regarding this problem ...

Problem-Centering vs. Means-Centering in Science

Philosophy of Science, 1946
ResumeMeans-centered approach to science is contrasted with a problem-centered orientation. Overstress on and too exclusive concern with method, instrument, technique or procedure fosters the following mistakes:1) Emphasis on polish and elegance rather than on vitality, significance and creativeness.2) Giving the commanding positions in science to ...

Reverse Center Location Problem

1999
In this paper we consider a reverse center location problem in which we wish to spend as less cost as possible to ensure that the distances from a given vertex to all other vertices in a network are within given upper bounds. We first show that this problem is NP-hard.

Customer-centered problem solving.

Hospital materiel management quarterly, 1999
If there is no single best way to attract new customers and retain current customers, there is surely an easy way to lose them: fail to solve the problems that arise in nearly every buyer-supplier relationship, or solve them in an unsatisfactory manner. Yet, all too frequently, companies do just that.
