Scheduling und Ressourcenplanung sind Aufgaben, die in vielen Einsatzbereichen wie z. B. der Maschinenbelegung oder Projektplanung vorkommen. In diesem Beitrag wird eine verwandte Aufgabenstellung vorgestellt, nämlich die Ressourcenund Jobplanung im Bereich des Grid-Computing. Auf Grund der Dynamik in einem solchen heterogenen Rechnernetz ist eine schnelle Reaktion und häufige Umplanung innerha...

This thesis introduces the DLXπ+, a super-pipelined processor with variable cycle time. The cycle time of the DLXπ+ may be as low as 9 gate delays (including 5 gate delays for registers), which is assumed to be a lower bound for the cycle time. For the parts of the DLXπ+ that significantly differ form previous implementations correctness proofs are provided. Formulas are developed which compute...

The extrusion of section from round billet poses a great challenge for theoretical modeling of the process using upper bound method. The greatest difficulty in three-dimensional upper bound method is to determine kinematically admissible velocity field. The SERR (Spatial Elementary Rigid Region) technique is fairly applicable for analyzing extrusion of sections having re-entrant corners. A modi...

in this study, the formation of different parts of a cup during deep drawing process has been investigated analytically using the geometrical relationships. for a given punch travel, the effects of the bending angle, and those of the die and shoulder radii on the flange and die shoulder strains were examined. in addition, different components of the deformation force were calculated and the pun...

nowadays two important discussions in academic parties all over the world are energy crisis and environment crisis. one of the strategies to deal with these crisises is using clean, renewable and domestic energy sources. one of the best renewable energies that can be used in different scales is solar energy. in iran which is considered among the greatest countries that receive huge amount of so...

Abstract The main aim of the current work is to investigate effect equal channel angular pressing (ECAP) processing parameters, namely, number passes, ECAP die angle, route type, and temperature on mechanical electrical properties pure copper (Cu). finite element method was used simulate homogeneity stress plastic strain distribution during processing. response surface methodology (RSM) identif...

machines using ball end mill cutters; the determination of the optimum tool and the minimization of the machining times for each surface. In the proposed methodology, the accessibility problem is first analyzed and then the optimal tool is selected from a database of tools. Next, and depending on the machining method, we select automatically the optimum sweeping method and the associated machin...

Following a review of the probe optimization of Slutsky, Rao, Sun, and Fainman @Phys. Rev. A 57, 2383 ~1998!# for the standard four-state protocol of quantum key distribution, I generalize the optimization to a variable angle between the signal bases. I calculate the corresponding maximum Renyi information gain by the probe, and determine the optimum probe parameters. A larger set of optimum pr...
