We show how dynamic price mechanisms can be used for decomposition and distributed optimization of control systems. A classical method to deal with optimization constraints is Lagrange relaxation, where dual variables are introduced in the optimization objective. When variables of different subproblems are connected by such constraints, the dual variables can be interpreted as prices in a market
This paper studies the future as “the only field of power, for we can act only on the future” (de Jouvenel 1967:5). As a number of scholars have pointed out (cf. Foucault 1991, Pred 2007) questions of knowledge is integral to political power, and this paper is about the production of knowledge of what can paradoxically not strictly speaking be known – a future space. I focus on how an interplay of
The adaptive resource management framework implemented in the European ACTORS project is presented. A resource manager has been developed that collaborates with a new Linux scheduler providing support for hard constant bandwidth server reservations, in order to adapt applications to changes in resource availability and to adapt the resource allocation to changes in application requirements. The fo
The extinction paradox states that a perfectly electric conducting target which is large compared to the wavelength removes from the incident radiation exactly twice the amount of power it can intercept by its geometrical cross section area. In this paper, the extinction paradox is generalized to include temporally dispersive material parameters with finite values of the permittivity and the perme
Accident risk in adverse conditions (wet/slippery road, darkness) increases drastically and speed adaptation in these conditions is often inappropriate. The safety potential of more appropriate speeds in these situations is high. Appropriate highest speeds in different conditions are discussed. A system, which limits the maximal speed of the vehicle in the actual situation (on wet/slippery road, a
