integrated data/voice circuit-switched networks which assume star topology consisting of local area networks (LANs) interconnected through backbone metropolitan area network (MAN). The stations are classified into two categories: data and voice stations. They are characterized by different arrival rate and session-length (holding time) statistics. A data (voice) session connection between a LAN-i station and a LAN-j station requires the allocation of a dedicated circuit (m circuits for voice) in the underlying LANs (i and j) and an interconne ....etc

IBM has created evolutionary solutions for data networks in anticipation of the dynamic trends and business advantages of integrating voice onto data networks. IBM's strategy is to provide high quality equipment and services with cost saving implementations that enable networks either to be upgraded using the installed base or architected to start simple and grow fast in cost-effective steps while accommodating new technologies or standards.

Voice and data integration is currently a hot topic within the business community, with its promise o ....etc

Introduction

In power electronics, solid-state electronics is used for the control and conversion of electric power .The goal of power electronics is to realize power conversion from electrical source to an electrical load in a highly efficient, highly reliable and cost effective way. Power electronics modules are key units in a power electronics system. These modules contain integration of power switches and associated electronic circuitry for drive control and protection and other passive components.

During the past decades, power devi ....etc

The NASA Integrated Vehicle Health Management (IVHM) Technology Experiment for X-37 was intended to run IVHM software on board the X-37 spacecraft. The X-37 is an unpiloted vehicle designed to orbit the Earth for up to 21days before landing on a runway.

The objectives of the experiment were to demonstrate the benefits of in-flight IVHM to the operation of a Reusable Launch Vehicle, to advance the Technology Readiness Level of this IVHM technology within a flight environment, and to demonstrate that the IVHM software could operate on the Veh ....etc

Divide and conquer has been the underlying principle used to solve many engineering and social problems. Over many years engineers have devised systematic ways to divide a design objective into a collection of smaller projects and tasks defined at multiple levels of abstraction. This approach has been quite successful in an environment where a large number of people with different types and levels of expertise work together to realize a given objective in a limited time. Communication system design is a perfect example of this pro ....etc

VLSI Scaling for Architects



The Buzz is VLSI Wires are Bad

A lot of talk about VLSI wires
being a problem:
– Delay
– Noise coupling
• What are the characteristics of
chip wires?
– How do they compare to
scaled gates?
• And what does it really mean?
– To CAD developers
– To architects


Predicting the Future
• Is very difficult
– The only guarantee is:
The future will happen, and you will be wrong
• Two approache ....etc

Embryonics is embryonic electronics. Working of multicellular organization in living beings suggests that concepts from biology can be applied to development of new embryonic integrated circuits. The final objective is the development of VLSI circuits that can partially reconstruct themselves in case of a minor fault (self-repair) or completely reconstruct the original device in case of major fault (self-replication). These features are advantageous for applications depending on high reliability, like avionics and medical electron ....etc
