the main objective of an extrusion die is flow balancing as an unbalanced flow causes a distorted product together with residual stress. in this paper a strategy is presented for flow balancing a u-shaped profile with different wall thicknesses. for this purpose, a choker bar is provided at thicker wall to locally restrict excessive flow passing through the thicker section. for optimal design s...

This paper introduces a novel approach towards balancing of nonlinear systems. It differs from other approaches in two key ideas: The first is the observation that linear timeinvariant systems have a single equilibrium point (the origin), and that the balanced realization for the class of a linear timeinvariant systems essentially relates to this equilibrium. This sparked the idea to consider b...

The load balancer is a fundamental building block for implementing high-throughput applications on multi-core architectures (e.g., network processors). In this paper, we consider two canonical load balancing schemes in the context of packet processing systems: (1) packet-level load balancing that determines the mapping of a packet to processor independently for each packet; and (2) flow-level l...

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...

As IPv6 deployment grows, it is important to develop new measurement techniques that allow us to study the IPv6 Internet. We implement an IPv6 version of the Multipath Detection Algorithm and use it from 12 geographically-distributed vantage points on two different platforms to characterize IPv6 routers that perform load balancing. Overall, we find that 74% of IPv6 routes traverse at least one ...

Computational fluid dynamic simulations were used to obtain a radially symmetrical flow profile at an aperture of microfluidic channel by manually arranging flow-directing obstacles around the aperture. For first time, was improved calculating coefficient variation (CoV), which applied velocity magnitude along coaxially arranged circles below in channel. A minimum CoV 0.03 obtained circle with ...

Many load balancing algorithms balance the load according to a topology. Its choice can significantly influence the performance of the algorithm. We consider the two phase balancing model. The first phase calculates a balancing flow with respect to this topology by a diffusion scheme. Its time requirement depends on the maximum node degree and on the number of eigenvalues of the network. The se...

In this paper, we evaluate the performance of packet-based load balancing in data center networks (DCNs). Throughput and flow completion time are some of the main the metrics considered to evaluate the performance of the transport of flows over the presence of long flows in a DCN. Load balancing in a DCN may improve those metrics but it may also generate out-of-order packet forwarding. Therefor...

This paper describes predictive load balancing schemes designed for use with parallel adaptive finite element methods. We provide an overview of data structures suitable for distributed storage of finite element mesh data as well as software designed for mesh adaptation and load balancing. During the course of a parallel computation, processor load imbalances are introduced at adaptive enrichme...
