Differential variational inequalities
International audienceThis paper introduces and studies the class of differential variational inequalities (DVIs) in a finite-dimensional Euclidean space. The DVI provides a powerful modeling paradigm for many applied problems in which dynamics, inequalities, and discontinuities are present; examples of such problems include constrained time-dependent physical systems with unilateral constraints, differential Nash games, and hybrid engineering systems with variable structures. The DVI unifies several mathematical problem classes that include ordinary differential equations (ODEs) with smooth and discontinuous right-hand sides, differential algebraic equations (DAEs), dynamic complementarity systems , and evolutionary variational inequalities. Conditions are presented under which the DVI can be converted, either locally or globally, to an equivalent ODE with a Lipschitz continuous right-hand function. For DVIs that cannot be so converted, we consider their numerical resolution via an Euler time-stepping procedure, which involves the solution of a sequence of finite-dimensiona
Proceedings of the Workshop on Space Telerobotics, volume 1
These proceedings report the results of a workshop on space telerobotics, which was held at the Jet Propulsion Laboratory, January 20-22, 1987. Sponsored by the NASA Office of Aeronautics and Space Technology (OAST), the Workshop reflected NASA's interest in developing new telerobotics technology for automating the space systems planned for the 1990s and beyond. The workshop provided a window into NASA telerobotics research, allowing leading researchers in telerobotics to exchange ideas on manipulation, control, system architectures, artificial intelligence, and machine sensing. One of the objectives was to identify important unsolved problems of current interest. The workshop consisted of surveys, tutorials, and contributed papers of both theoretical and practical interest. Several sessions were held on the themes of sensing and perception, control execution, operator interface, planning and reasoning, and system architecture

Memorias del V Congreso Latinoamericano de Agroecología - SOCLA : Trabajos científicos y relatos de experiencias: la agroecología, un nuevo paradigma para redefinir la investigación, la educación y la extensión para una agricultura sustentable
Este libro reúne los resúmenes de trabajos científicos y relatos de experiencias presentados en el V Congreso Latinoamericano de Agroecología, organizado por la Sociedad Científica Latinoamericana de Agroecología, que tuvo lugar en la ciudad de La Plata, Argentina, del 7 al 9 de Octubre del 2015. Los trabajos y experiencias abordan diferentes líneas temáticas del amplio campo de la Agroecología y tienen como objetivos: a) contribuir a la difusión de los avances en investigación agroecológica en Latinoamérica, b) promover la discusión y propuestas para el mejoramiento de la soberanía alimentaria y estrategias frente al cambio climático en la región, c) fomentar el intercambio e integración de conocimientos entre investigadores, técnicos, productores, campesinos y la sociedad civil, d) promover la enseñanza, investigación e innovaciones en Agroecología en la comunidad científica internacional.Facultad de Ciencias Agrarias y Forestales (FCAF
