Training simulations, especially those for tactical training, require properly behaving computer generated forces (CGFs) in the opponent role for an effective training experience. Traditionally, the behavior of such CGFs is controlled through scripts. There are two main problems with the use of scripts for controlling the behavior of CGFs: (1) building an effective script requires expert knowle...

In urban Vehicular Ad Hoc Network (VANET) environments, buildings play a crucial role as they can act obstacles that attenuate the transmission signal between vehicles. Such lead to multipath effects, which could substantially impact data due fading. Therefore, quantifying of on quality is key parameter propagation model, especially in critical scenarios involving emergency vehicles where relia...

The design and implementation of a large-coverage computational grammar of French is described. This grammar is compared to a comprehensive computational grammar of English which was implemented using the same computer workbench. Although many similarities may be observed in the two grammars, there are important structural d i f ferences which can be traced back to features specific to the F~'e...

Occupying more than 70% of the concrete’s volume, aggregates play a vital role as the raw feed for construction materials; particularly in the production of concrete and concrete products. Often, the characteristics such as shape, size and surface texture of aggregates significantly affect the quality of the construction materials produced. This article discusses a novel method for automatic cl...

Targeting behavior of vehicles in the battlefield (Target Analysis) is one of the most critical tasks in Computer Generated Forces (CGF) systems. This is simply because of many complex and ambiguous factors that can effect the targeting behavior of such systems in the real world. There has been many approaches including using Fuzzy Set Theory for Target Analysis. Target detection, and threat an...

Systemic autoimmune diseases represented by systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) are characterized by hyperactivation of B cells and the production of various autoantibodies. Several studies in murine systems suggest that the deregulation of lymphokine production or the production of abnormal lymphokines could be responsible for hyperactivation of autoantibodyproduci...

Although most skeletal muscle genes are expressed at similar levels in electrically active, innervated muscle and in electrically inactive, denervated muscle, a small number of genes, including those encoding the acetylcholine receptor, N-CAM, and myogenin, are expressed at significantly higher levels in denervated than in innervated muscle. The mechanisms that mediate electrical activity-depen...

A core educational goal is to produce self-directed lifelong learners who have acquired or are able to acquire the knowledge and skills necessary for their future professional workplace in a networked world. Constructivist and socio-constructivist theories of learning and instruction recommend using collaborative learning scenarios in all kinds of educational contexts in order to attain this go...

We describe several approaches to visualising data contained in log les which record the stream of events from various simulation applications. Besides identifying several existing useful techniques, we also report experience with the use of VRML 2.0 to reanimate log les into three-dimensional movies of the events they record. Reanimation is a particularly promising technique, both for assistin...
