In the solution of Fluid-Structure Interaction problems, partitioned procedures are modular algorithms that involve separate fluid and structure solvers, that interact, in an iterative framework, through the exchange of suitable transmission conditions at the FS interface. In this work we study, using Fourier analysis, the convergence of partitioned algorithms based on Robin transmission condit...

The report evaluates transmission pricing methods under liberalized market conditions. Several concepts are being discussed, whereas three main categories can be distinguished: rolled-in transmission pricing, incremental transmission pricing and embedded/incremental transmission pricing. In order to clarify the general framework in which electricity trading and therefore transmission takes plac...

In this paper, we study the performance of an adaptive and fixed transmission schemes where the transmission probability varies according to the evolution of the cluster formation procedure or is fixed for the entire network lifetime, respectively. Also, we propose a hybrid scheme where the transmission probability can either be fixed or adaptive according to the system’s conditions. In order t...

Reflection and transmission of plane waves between two initially stressed thermoelastic half-spaces with orthotropic type of anisotropy is studied. Incidence of a SV-type wave from the lower half-space is considered and the amplitude ratios of the reflected and transmitted SV-wave, P-wave and thermal wave are obtained by using appropriate boundary conditions. Numerical computation for a particu...

The exploitation of fluctuating channel conditions in link adaption techniques for unicast transmission has been shown to provide large system capacity gains. However, the problem of choosing transmission rates for multicast transmission has not been thoroughly investigated. In this paper, we investigate multicast adaptive techniques for reliable data delivery in GEO satellite networks. An opti...

We present and study a homographic best approximation problem, which arises in the analysis of waveform relaxation algorithms with optimized transmission conditions. Its solution characterizes in each class of transmission conditions the one with the best performance of the associated waveform relaxation algorithm. We present the particular class of first order transmission conditions in detail...
