Sending IP packets over multiple parallel links is in extensive use in today’s Internet and its use is growing due to its scalability, reliability and cost-effectiveness. To maximize the efficiency of parallel links, load balancing is necessary among the links, but it may cause the problem of packet reordering. Since packet reordering impairs TCP performance, it is important to reduce the amoun...

With increasing line speed and enlarging spectra of attacks, Intrusion Detection Systems (IDSes) have to move to multi-core platform to be able to keep up with the security risks. A major issue in this way is the issue of Load Balancing (LB). This problem has attracted some interests in the past years and flow based techniques have been proposed. However, flow based LB schemes cannot fully expl...

Computational fluid dynamics (CFD) flow simulations are extremely expensive in terms of CPU time and memory. In this study, parallel computing and grid adaptation techniques are employed to achieve high efficiency and accuracy in a hybrid unstructured flow solver. However, adaptive local grid refinement/coarsening causes the unequal distribution of workload among the processors at run time. A s...

In present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. A double active sites model for Ziegler-Natta catalysts is used for simulation of polymerization reaction. Hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with different...

We have developed WaterWOLF, a new electronic system and signal processing algorithm for evaluating flow components in pipes. These techniques nonintrusively convert an existing flow meter into a high resolution wireless meter for determining flow rates in real-time. These techniques exploit new tunneling magneto-resistive materials (TMR) for detecting very small magnetic fields generated by ce...

abstract in this study, the effect of suspended load transport on the characteristics of submerged hydraulic jump (shj) in a rectangular channel was investigated experimentally. sediment concentration and jet froude numbers in the range of 0.424%-16.15% and 1.93-4.96, respectively, were considered. tow grain size 0.15 and 0.03 mm were used in the experiments. characteristics of submerged hydrau...

Radial distribution systems (RDS) require special load flow methods to solve power flow equations owing to their high R/X ratio. Increasing use of power electronic devices and effect of magnetic saturation cause harmonics in RDS. This paper proposes a novel algorithm to compute the power flow solution of a RDS accounting for all the harmonic components. It uses a recursive solution technique. T...

Load Flow Study (LFS) is the heart of most system-planning studies and also the starting point for transient and dynamic stability studies. The load flow problem models the nonlinear relationships among bus power injections, power demands, and bus voltages and angles, with the network constants providing the circuit parameters. This article provides formulations of the load LFSs. Load Flow are ...
