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.

Taking PC/104 CPU Boards to the Next Performance Level

Since their introduction in 1991, PC/104 standard based systems have been widely adopted in various applications. Unmanned aircraft control, onboard vehicle control and navigation systems, personal communicators, add-on cards for customer specific boards, all utilize PC/104 technology. Many system developers choose this form-factor due to its advantages in terms of low weight, compact size (boards are just 90×96 mm), ease of application development and modification, and mechanical reliability.

Understanding the Unique Requirements of Portable Data Acquisition Systems

Portable data acquisition applications have to meet a number of stringent requirements not present in traditional laboratory systems. Environmental conditions such as extremes in temperature, humidity, shock and vibration, are all factors that must be considered when selecting portable data acquisition equipment. Other concerns include whether the data acquisition equipment is capable of supporting the mix of particular sensors that will be used, as well as if there is adequate memory/storage to support the test.
