in this paper, optimal distributed control of the time-dependent navier-stokes equations is considered. the control problem involves the minimization of a measure of the distance between the velocity field and a given target velocity field. a mixed numerical method involving a quasi-newton algorithm, a novel calculation of the gradients and an inhomogeneous navier-stokes solver, to find the opt...

In behavior-oriented robotics, the control of a system is distributed over various processes or behaviors running in virtual parallel. But the assignment of processing power to different processes is a non-trivial task. Existing approaches to this problem like rate-monotonic scheduling focus on the fulfillment of deadlines, i.e., upper time-bounds. For behavioral control, the periodicy of proce...

the present work reports and discusses the results of a 3d simulation of the injection molding process of a rubber compound that includes the mold flling stage and  material curing, using the computer code is developed in “udf” part of the fluent 6.3 cae software. the data obtained from a rheometer (mdr 2000) is used to characterize the rubber material in order to fnd the cure model parameters ...

In acoustic communication timing seems to be an exceedingly important aspect. The just noticeable difference ~jnd! for small perturbations of an isochronous sequence of sounds is particularly important in music, in which such sequences frequently occur. This article reviews the literature in the area and presents an experiment designed to resolve some conflicting results in the literature regar...

Latest real-time systems are capable of changing its speed at run time to prolong its battery life and, demand efficient techniques for online decisions making. Available real time feasibility tests have pseudo-polynomial complexity and can not be executed online. This paper proposes that the time complexity of existing techniques could be lowered when task schedulability is analyzed at points,...

The essential goal of the Rate Monotonic Analysis (RMA) for RealTime Systems Project at the Software Engineering Institute is to catalyze improvement in the practice of real-time systems engineering, specifically by increasing the use of rate monotonic analysis and scheduling algorithms. In this report, we review important decisions in the development of RMA. Our experience indicates that techn...

in this paper the numerical analysis of flow and time dependent heat transfer of micro-tube conveying nanofluid in laminar flow is investigated. in this study, convection heat transfer of nanofluid and base fluid and transient analysis for time-varying heat flux for time step of 0.0001 second are elucidated. it is observed that the pumping power of nanofluid flowing and the maximum temperature ...

We propose a new paradigm for time-series learning where users implicitly specify families of signal shapes by choosing monotonic parameterized signal predicates. These families of predicates (also called specifications) can be seen as infinite Boolean feature vectors, that are able to leverage a user’s domain expertise and have the property that as the parameter values increase, the specificat...
