1000-Watt Power Supply

Lambda (San Diego, CA) has introduced the HWS1000 series of 1000-watt power supplies. The single-output power supplies are ideal for powering process control equipment, ATE, and factory automation systems. The power supplies meet the SEMI F4 power line sag specs. The units are available in 10 nominal output voltages including: 3.3, 5, 6, 7.5, 12, 15, 24, 36, 48, and 60-volts. Most models can be adjusted up to ±20% of nominal voltage to accommodate non-standard system voltages. The 7 through 60-volt models have a peak power rating of up to 1200-watts when operated with a line voltage of 200VAC or higher.

The Ballistic Missile Defense System: An Integrated Approach to Global Defense

Although the end of the Cold War signaled a reduction in the likelihood of global nuclear conflict, the threat from ballistic missiles has grown steadily as sophisticated missile technology becomes available on a wider scale to countries hostile to the U.S. and its allies.

Data-Centric Distributed Application Architecture for Shipboard Systems

System architects design distributed applications leveraging computer resources connected by a network infrastructure: CPU-intensive tasks may be located on powerful core servers; application-data storage may be managed by specialized database servers; and data-collection, actuation, and user interaction may occur on nodes located at the edge of the network. The architecture must accommodate coordination of the distributed resources as well as ensuring that the necessary data is available to all the computation, decision- making, and visualization nodes.

Continuous Carbon Nanofibers for Structural Composites

A program of research has addressed key issues in the production of continuous carbon nanofibers and the utilization of carbon nanofibers as the reinforcing components in matrix/fiber composite materials. The goal of this research is to contribute to the development of advanced lightweight structural composites in which the exceptionally high strengths of carbon nanofibers are exploited to obtain mechanical strengths, delamination toughnesses, and fatigue lives greater than would otherwise be possible.

High-Strain-Rate Tests of Epoxy/Aluminum-Powder Composites

Initial tests have been performed in a continuing experimental study to determine selected mechanical properties, at high strain rates, of an epoxy and of composite materials consisting of the epoxy filled with aluminum powders. These composites are examples of the large variety of polymer-matrix/particlefilling composites in general, which are widely used in military and civilian applications. The properties of such composites can be tailored for specific applications through appropriate choices of constituent materials, the proportions of the constituent materials, and the sizes of the particles. Especially in aerospace structural applications, the composites are exposed to complex, temporally varying loads. Therefore, the mechanical properties of such composites’ high strain rates are of increasing importance.
