On 4-connected geometric graphs
(2013)
Given a set S of n points in the plane, in this paper we give a necessary and sometimes sufficient condition to build a 4-connected non-crossing geometric graph on S.

Finding a widest empty 1-corner corridor
(2004)
Given a set of n points in the plane, we consider the problem of computing a widest empty 1-corner corridor. We star giving a characterization of the 1-corner corridors that we call locally widest. Our approach to finding ...

The variance location problem on a network with continuously distributed demand
(EDP Sciences, 2002-08-15)
Most location problems on networks consider discrete nodal demand. However, for many problems, demands are better represented by continuous functions along the edges, in addition to nodal demands. Several papers consider ...

Nonlinear age-dependent diffusive equations: a bifurcation approach
(Elsevier, 2008-05-01)
The main goal of this paper is the study of the existence and uniqueness of positive solutions of some nonlinear age-dependent diffusive models, arising from dynamic populations. We use bifurcation method, for which it has ...

Integration Operators in Average Radial Integrability Spaces of Analytic Functions
(Springer, 2021)
In this paper we characterize the boundedness, compactness, and weak compactness of the integration operators Tg(f)(z) = ˆ z 0 f(w)g (w) dw acting on the average radial integrability spaces RM(p, q). For these purposes, ...

Cooperación parcial en juegos de n-personas
(1996)
"La teoría de juegos fue fundada por John von Neumann en 1928 [64]. Esta moderna aproximación a los problemas de cooperación y competición se redescubrió cuando von Neumann escribe un tratado con el economista Oskar ...

Relating disease and predation: equilibria of an epidemic model
(Wiley, 2005)
In this paper, we would like compare the spread of an infectious disease in a population without the influence of a predator and under its influence. We show that it is possible to control an epidemic in a population with ...

Variable-Angle Phase-Shifted PWM for Multilevel Three-Cell Cascaded H-bridge Converters
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Multilevel cascaded H-bridge converters have become a mature technology for applications where high-power medium ac voltages are required. Normal operation of multilevel cascaded H-bridge converters assumes that all power ...

Benders decomposition for network design covering problems
(Publisher Elsevier Ltd, 2022)
We consider two covering variants of the network design problem. We are given a set of origin/destination pairs, called O/D pairs, and each such O/D pair is covered if there exists a path in the network from the origin to ...
