Embedded system design requires the use of eecient scheduling policies to execute on shared resources, e.g. the processor, algorithms that consist of a set of concurrent tasks with complex mutual dependencies. Scheduling techniques are called static when the schedule is computed at compile time, dynamic when some or all decisions are made at run-time. The choice of the scheduling policy mainly ...

Previous work introduced a dynamic compute model aimed at eliminating existing barriers to the widespread efficient exploitation of reconfigurable devices. Among other achievements this model decoupled application design-time decisions from the run-time physical resource bindings. The compute model uses graphs of compute pages and memory blocks connected by stream links to capture the definitio...

RVC-CAL is an actor-based dataflow language that enables concurrent, modular and portable description of signal processing algorithms. RVC-CAL programs can be compiled to implementation languages such as C/C++ and VHDL for producing software or hardware implementations. This paper presents a methodology for automatic discovery of piecewise-deterministic (quasi-static) execution schedules for RV...

Quasi-Static analysis of moored vessels is vastly used for engineering designs, as a substitute to the numerical simulation of dynamic mooring analysis. Yet, the level of validity of the results of quasi-static analysis is a matter of discussion. In the present study, the validation of the assumptions behind the quasi-static analysis of mooring vessels is examined with application of a dynamic ...

In this paper we develop an OcTree discretization for Maxwell’s equations in the quasi-static regime. We then use this discretization in order to develop a multigrid method for Maxwell’s equations with highly discontinuous coefficients. We test our algorithms and compare it to other multilevel algorithms.

A variable stiffness and damping isolator (VSDI) is designed and developed employing MREs. A double lap shear test has been carried out to characterize two MRE based VSDIs under quasi-static shear loading. A phenomenological model which can capture the behavior of the VSDI is developed and related parameters are identified using experimental data. Both experimental and theoretical modeling resu...
