SRAM-based Field Programmable Gate Arrays (FPGAs) are very susceptible to Single Event Upsets (SEUs) that may have dramatic effects on the circuits they implement. In this paper we present a design flow composed by both standard tools, and ad-hoc developed tools, which designers can use fruitfully for developing circuits resilient to SEUs. Experiments are reported on both benchmarks circuits an...

This paper describes the design, implementation, and testing of an edge router supporting flow-based classification functions for real time traffic. Protocol and statistical analysis of application flows is performed to provide EF treatment to multimedia traffic without any user signaling. These functions take advantage of the modular Click environment and implement per flow traffic recognition...

Momentum considerations are used to derive relationships between the lifting efficieny of a wing having an attached shock system and properties of the flow field around it. Optimum two-dimensional flow fields are derived using shock expansion theory. These may be used to design three-dimensional shapes having slightly greater lifting efficiencies than plane wedges. An analysis of the flow in an...

The complexity of designing electronic systems and products is constantly increasing. The increasing complexity is due to the factors such as: portability, increased complexities of software and hardware, low power and high speed applications etc. Due to all these factors the electronic system design is moving towards System on Chip (SoC) with heterogeneous components like DSP, FPGA etc. This c...

there are several sources for pressure oscillations in solid propellant rocket motors. oscillatory flow field is one of them. free shear layers in motor flow field cause vortex shedding. end edges of propellant grains and baffle edge in two-segmented motors are samples of such zones. these vortices move from their forming points and strike the field walls. the kinetic energy of vortices change ...

This paper presents the simulations for a two-dimensional PEMFC with an interdigitated flow channel design using FEMLAB. The multi-species flow of O2, H2, H2O and inert N2 is examined over the entire fuel cell working range. The transportations of these gases in the porous anode/cathode are predicted using the Maxwell-Stefan transport equations and the Fick’s law; the flow field is predicted us...

This paper presents a limited survey of methods and multidisciplinary applications of various techniques for the solution of several classes of inverse problems as developed and practiced by our research team. Sketches of solution methods for inverse problems of shape determination, boundary conditions determination, sources determination, and physical properties determination are presented fro...

With the I-type plastic extrusion die for example, the advantages and disadvantages between the traditional design method and optimization design method were compared. The design was studied via finite element numeric analysis combined with optimization, whose objective was the equal average flow velocity of each sub-field of profile cross section at extrusion die. And the optimization design w...

The availability of petroleum which continues to decrease and the level public consumption is always increasing are serious problems today. Renewable energy needs be researched on an ongoing basis anticipate above. Proton Exchange Membrane Fuel Cell (PEMFC) environmentally friendly source electrical because it only requires hydrogen oxygen as raw materials water a result reaction. This study wi...
