Passive flow control techniques, and particularly vortex generators have been used successfully in a broad range of aero- hydrodynamics applications to alter the characteristics boundary layer separation. This study aims review how such techniques can mitigate extent impact cavitation incompressible flows. focuses first on characterize key physical principles. It then considers complete passive...

This article reports the active control of base flows using the experimental procedure. Active control of base pressure helps in reducing the base drag in aerodynamic devices having suddenly expanded flows. Active control in the form of microjets having 0.5 mm radius placed at forty-five degrees apart is employed to control the base pressure. The Mach numbers of the present analysis are 1.7, 2....

This paper proposes a Flexible Power Electronic Transformer (FPET) for the application in the micro-grids. The low frequency transformer is usually used at the Point of Common Coupling (PCC) to connect the low voltage grid and utility network to each other. The conventional 50Hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. In this pap...

In many massively parallel data management platforms, programs are represented as small imperative pieces of code connected in a data flow. This popular abstraction makes it hard to apply algebraic reordering techniques employed by relational DBMSs and other systems that use an algebraic programming abstraction. We present a code analysis technique based on reverse data and control flow analysi...

When two methods are invoked on the same object, the dispatch behaviours of these method calls will be correlated. If two correlated method calls are polymorphic (i.e., they dispatch to different method definitions depending on the type of the receiver object), a program’s interprocedural control flow graph will contain infeasible paths. Existing algorithms for data-flow analysis are unable to ...

The effective usages of computational resources are a primary concern of up-to-date distributed applications. In this paper, we present a methodology to reason about resource usages (acquisition, release, revision, ...), and therefore the proposed approach enables to predict bad usages of resources. Keeping in mind the interplay between local and global information occurring in the application-...
