Dyna is a single-agent architectural framework that integrates learning, planning, and reacting. Well known instantiations of Dyna are Dyna-AC and Dyna-Q. Here a multiagent extension of Dyna-Q is presented. This extension, called M-Dyna-Q, constitutes a novel coordination framework that bridges the gap between plan-based and reactive coordination in multiagent systems. The paper summarizes the ...

There are several techniques to simulate rebar reinforced concrete, such as smeared model, discrete embedded CLIS (constrained Lagrange in solid) and CBIS beam model. In this study, however, the interaction between concrete elements reinforcement is only simulated by model The efficiency accuracy comparisons investigated with reference analysis results both models provided LS-DYNA explicit fini...

For stochastic simulations usually many simulations are performed, therefore much information is available for the simulation engineer. In order to evaluate this information and to assess the results of stochastic investigations software tools such as LS-OPT and D-SPEX are available. Good and clearly arranged presentation of the results is important, so that the engineer really benefit from the...

In order to solve the problem of high straw content in recovered residual film and low rate qualified crushing combination with a front-mounted cotton-straw-crushing device, cutting mechanisms cotton stalks were studied based on ANSYS/LS-DYNA. The height h dip angle α fixed blade determined be 30 mm 75° through finite element analysis. On basis device design, explicit dynamic models single stal...

The residual stresses in the blank after forming are the main cause for the subsequent springback in a sheet forming operation. The accuracy of the predicted springback in a Finite Element simulation of the forming operation is very much determined by the quality of the material modeling. Those parts of the workpiece, which in particular contribute to the global springback, have usually been su...
