Ocean wave simulation has a wide range of applications in movies, video games and training systems. Wind force is the main energy resource for generating ocean waves, which are the result of the interaction between wind and the ocean surface. While numerous methods to handle simulating oceans and other fluid phenomena have undergone rapid development during the past years in the field of comput...

There are many domains that still require use of complex manual control, despite the general shift in the field toward research on supervisory control. One of the problems in complex manual control is training; we currently lack models that can help guide training. The research reported here is part of an effort to fill that gap. In this study, we used the Neverball video game as a motor contro...

A unique hallmark of human language is that it uses signals that are both learnt and symbolic. The emergence of such signals was therefore a defining event in human cognitive evolution, yet very little is known about how such a process occurs. Previous work provides some insights on how meaning can become attached to form, but a more foundational issue is presently unaddressed. How does a signa...

it is usual to rank the participating countries in olympic games in accordance with the number of medals they have won. but it should be mentioned that achieving competition output (medals acquired) is possible only through utilization of input and appropriate processes. so, lower input should be considered along with higher outputs to evaluate more precisely and regularly. in this study, one o...

the purpose of this study was to determine tv and computer games in underweight and obese boys and their relationship with physical activity, fitness and body composition. 482 male students (9 to 15 years old) participated in this study. they were selected from state (n=286) and private (n=196) schools. subjects were sampled in two stages; at first, cluster sampling was randomly performed and s...
