Witteveen, J. (author)De bekende differentiemethode bij het berekenen van platen met constante dikte, welke tot voor enkele jaren zeer bewerkelijk was, verdient opnieuw de aandacht, omdat dit bezwaar door de komst van elektronische rekenmachines is ondervangen. Het wordt nu ook interessant aan de methode een uitbreiding te geven voor platen waarvan de dikte in twee...journal article 1965

Witteveen, J. (author)The well-known method of differences for the analysis of plates of constant thickness, which until a few years ago was very laborious, deserves renewed attention because the advent of the electronic computer has removed this drawback. It is now also rif interest to extend the method to plates whose thickness changes abruptly at regular distances...journal article 1966

Witteveen, J. (author)Na een verklarende inleiding wordt het gedrag besproken van parallelogramvormige platen in de hoekpunten belast met afwisselend naar boven, resp. naar beneden gerichte puntlasten. Bijzondere gevallen hiervan zijn de vierkante plaat, bekend als het belastingsgeval van Nadai, en de ruitvormige plaat. Met behulp van dit laatste belastingsgeval kan...journal article 1967

Vrouwenvelder, A. (author), Witteveen, J. (author)An approximate method for the elastic buckling analysis of two-dimensional frames is introduced. The method can conveniently be explained with reference to a physical interpretation: In the frame every member is replaced by two new members: - a flexural member without extensional rigidity to transmit the shear force and the bending moments; - a...journal article 1975

De Weerdt, M.M. (author), Bos, A. (author), Tonino, J.F.M. (author), Witteveen, C. (author)We introduce an algorithm for cooperative planning in multi-agent systems. The algorithm enables the agents to combine (fuse) their plans in order to increase their joint profits. A computational resources and skills framework is developed for representing the planned activities of an agent under time constraints. Using this resource-skill...conference paper 2000

De Weerdt, M.M. (author), Bos, A. (author), Tonino, J.F.M. (author), Witteveen, C. (author)The promise of multi-agent systems is that multiple agents can solve problems more efficiently than single agents can. In this paper we propose a method to implement cooperation between agents in the planning phase, in order to achive more cost-effective solutions than without cooperation. Two results are presented: First of all, we introduce a...conference paper 2000

De Weerdt, M.M. (author), Tonino, J.F.M. (author), Witteveen, C. (author)In this paper we will use the framework to study cooperative heuristic multi-agent planning. During the construction of their plans, the agents use a heuristic function inspired by the FF planner (l3l). At any time in the process of planning the agents may exchange available resources, or they may request an agent to produce a missing resource....conference paper 2001
