In a computer supported cooperative work (CSCW), data consistency between collaborating users is crucial issue. Based on the type of application, ensuring can be lengthy process that takes time and affects system’s performance. most 3D terrain are massive due to its size. Exchanging this may expensive cause significant delay. real-time collaborative editor, issue becomes more exchange consisten...

The creative cognition approach views creativity as the generation of novel and appropriate products through the application of basic cognitive processes to existing knowledge structures. It relies on converging evidence from anecdotal accounts of creativity and tightly controlled laboratory studies designed to examine the processes that are assumed to operate in those anecdotes. Specific examp...

There are many applications that require rendered 3D terrain, whether it be computer games or complex geographical research. The methods used to represent terrain, generate realistic terrain and render terrain are studied in an attempt to better understand how people have previously tackled the key issues. The idea of fractal nature is studied and the effects, positive and negative, this has on...

This paper presents a new strategy for behavior-based navigation of field mobile robots on challenging terrain, using a fuzzy logic approach and a novel measure of terrain traversability. A key feature of the proposed approach is real-time assessment of terrain characteristics and incorporation of this information in the robot navigation strategy. Three terrain characteristics that strongly aff...

It is inadequate to just assure the functional requirements. Quality of service (QoS) must also be satisfied. An important challenge for developing efficient Service Oriented Architecture (SOA) is to maintain the QoS attributes because of compositional and dynamical environment of SOA. It is significant to scrutinize how quality attributes are supported by SOA. However, implementation of SOA pr...

Military training instructors increasingly often employ computer games to train soldiers in all sorts of skills and tactics. One of the difficulties instructors face when using games as a training tool is the creation of suitable content, including scenarios, entities and corresponding terrain models. Terrain plays a key role in many military training games, as for example in our case game Tact...

An important problem faced by boundedly rational agents is to identify “regions of rationality,” i.e., the areas for which simple, boundedly rational models are and are not effective. To map the contours of such regions, we derive probabilities that models identify the best of m alternatives (m > 2) characterized by k attributes (k > 1). The models include a single variable (lexicographic), var...

Wireless Sensor Networks (WSNs) are composed by a large number of sensor nodes, which are usually small in size and are deployed inside or close to some phenomenon of interest. Moreover, since usually there is no need for regular or predefined deployment, the sensors can be placed over irregular or inaccessible areas. Therefore, according to [2], it is expected that the sensors possess self-org...

This paper presents an global-optimal motion planner for Mars Rover. It accounts for traversability and dynamic stability due to vehicle dynamics and terrain topography. A given path is traversable if along it the vehicle is statically stable. The vehicle is dynamically stable if its velocity does not exceed the velocity limit, determined from tip-over, sliding, and contact constraints. The cos...
