There are many practical gains that JCATS can provide today's military with regard to training and educating soldiers for future conflicts. JCATS can be used to train soldiers in planning and executing missions in ways not feasible with conventional field training exercises utilizing live bodies and real vehicles. It is also increasingly being used for actual mission planning. However, very little has been done using JCATS to war-game past operations. There are two points to be gained by using JCATS to model a historical battle such as the Battle of Little Bighorn. First, it validates the ability of JCATS to accurately model actual historical scenarios while identifying many of the specific limitations of the program. If the military is going to use computer simulations such as JCATS in lieu of field training exercises to train soldiers, it must first be determined if the program produces realistic results. Modeling an actual battle and comparing the results of the program with what actually occurred is one means of doing so. Second, modeling historical battles, particularly defeats, may assist in discovering lessons learned. In a field training exercise, a defeated force can be brought back to life and given another opportunity to apply the lessons learned from its previous defeat. Real battles afford no such opportunity. Computer modeling of past battles would allow military planners to isolate individual events and decisions and study their impact on the outcome. / Major, United States Army

A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, for the degree Master of Science / The recording of seismic signals in remote areas requires a portable, low power recording system that can be left in the field for a few weeks at a time. Three components of ground motion are generally measured, and some form of event recording, rather than continuous recording should be available. [Abbreviated abstract.

The need to achieve dependability in critical infrastructures has become indispensable for government and commercial enterprises. This need has become more necessary with the proliferation of malicious attacks on critical systems, such as healthcare, aerospace and airline applications. Additionally, due to the widespread use of web services in critical systems, the need to ensure their reliability is paramount. We believe that patterns can be used to achieve dependability. We conducted a survey of fault tolerance, reliability and web service products and patterns to better understand them. One objective of our survey is to evaluate the state of these patterns, and to investigate which standards are being used in products and their tool support. Our survey found that these patterns are insufficient, and many web services products do not use them. In light of this, we wrote some fault tolerance and web services reliability patterns and present an analysis of them. / by Ingrid A.

Reliability is a key system characteristic that is an increasing concern for current systems. Greater reliability is necessary due to the new ways in which services are delivered to the public. Services are used by many industries, including health care, government, telecommunications, tools, and products. We have defined an approach to incorporate reliability along the stages of system development. We first did a survey of existing dependability patterns to evaluate their possible use in this methodology. We have defined a systematic methodology that helps the designer apply reliability in all steps of the development life cycle in the form of patterns. A systematic failure enumeration process to define corresponding countermeasures was proposed as a guideline to define where reliability is needed. We introduced the idea of failure patterns which show how failures manifest and propagate in a system. We also looked at how to combine reliability and security. Finally, we defined an approach to certify the level of reliability of an implemented web service. All these steps lead towards a complete methodology. / by Ingrid A.
