Recent developments in the simulation capabilities of high level mathematical modeling tools have opened exciting new design flow possibilities. System level support for bit true modeling enables a designer to use a single environment to create floating and fixedpoint models, and to make scaling and rounding decisions early in the design process. At the same time, FPGA vendors have expanded com...

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...

Nowadays, significant deficiencies exist in the information flow and access along the NC (Numerical Control) process chain. These deficiencies are solved insufficiently by introducing CAD/CAM systems and feature-oriented specification languages. In contrast the application of new production and new machining systems requires an intensive information exchange. The introduced approach enables the...

This paper presents a path-planning paradigm for distributed control of multiple sensor platforms in a geophysical flow well-approximated by a point-vortex model. We utilize Hamiltonian dynamics to generate control vector fields for vehicle motion in N -vortex flows using the concept of an active singularity whose strength is a tunable control input. We introduce active singularities that are v...

MENTOR (Mesh Network Topological Optimization and Routing) is an efficient heuristic design algorithm network that assigns traffic flow while selecting links to be installed. MENTOR is suitable to design networks categorized as virtual circuit packet switching such as Frame Relay, ATM and MPLS networks. However, MENTOR cannot be directly applied to datagram packet switching networks such as pur...

This document specifies protocol stacks for the routing and transport of per-flow signalling messages along the path taken by that flow through the network. The design uses existing transport and security protocols under a common messaging layer, the General Internet Signalling Transport (GIST), which provides a common service for diverse signalling applications. GIST does not handle signalling...

This paper studies the capacity and flow assignment problem arising in the design of self-healing asynchronous transfer mode (ATM) networks using the virtual path concept. The problem is formulated here as a linear programming problem which is solved using standard methods. The objective is to minimize the spare capacity cost for the given restoration requirement. The spare cost depends on the ...

Complexity demand of modern communication systems, particularly in the wireless domain, grows at an astounding rate, a rate so high that the available complexity and even worse the design productivity required to convert algorithms into silicon are left far behind. This effect is commonly referred to as the design productivity crisis or simply the design gap. Since the design gap is predicted t...
