Abstract. Duality theory has played a key role in convex programming in the absence of data uncertainty. In this paper, we present a duality theory for convex programming problems in the face of data uncertainty via robust optimization. We characterize strong duality between the robust counterpart of an uncertain convex program and the optimistic counterpart of its uncertain Lagrangian dual. We...

Tanulmányunkban arra a kérdésre kerestük választ, hogy tudásalapú gazdaság korszakában milyen fejlődési utakat járhat be jelenlegi fejlettségi szintjének fényében hazai szakképzés. Ennek érdekében szakképzés történetének áttekintését és annak állapotát – területi differenciáltságát gazdasági fejlettséghez kötődő kapcsolatának vizsgálatát végeztük el. A vizsgálat eredményeként megállapítható, ma...

SPQR + ISocRob is a joint team between two research groups: SPQR (Italy) and IsocRob (Portugal). SPQR (Soccer Player Quadruped Robots) is the group of the Faculty of Engineering at University of Rome “La Sapienza” in Italy, that is involved in RoboCup competitions since 1998 in different leagues (Middle-size 1998-2002, Four-legged since 2000, Real-rescue-robots since 2003, Virtual-rescue and @H...

New theorems of the alternative for polynomial constraints (based on the Positivstellensatz from real algebraic geometry) and for linear constraints (generalizing the transposition theorems of Motzkin and Tucker) are proved. Based on these, two Karush-John optimality conditions – holding without any constraint qualification – are proved for singleor multi-objective constrained optimization prob...

This work presents the procedure qualification for pipeline orbital welding using a robotic system. The system has four degrees of freedom, which allow the controlling of the stick out, the travel speed, the torch angle and the positioning. The arc voltage and welding current are also controlled during the welding, although the system uses a conventional power source. With the system it is poss...

There is a dilemma between, on the one hand, easily and straightforwardly acquiring and integrating external, prefabricated, cost-effective, plug & play components and, on the other hand, the strong need for assessing and possibly accepting these components so that their incorporation into in-house products is not the source of any damage. This paper supplies some technical leads based on the c...
