Railway tunnel 3D clearance inspection is critical to guaranteeing railway operation safety. However, it is a challenge to inspect railway tunnel 3D clearance using a vision system, because both the spatial range and field of view (FOV) of such measurements are quite large. This paper summarizes our work on dynamic railway tunnel 3D clearance inspection based on a multi-camera and structured-li...

Article History: The present study used a between subjects, post-test only design to investigate the impact of Submitted on 21 April 2011 background music (low tempo music vs. high tempo music) on arousal and aggression of a player playing a first person shooter video game: Counter-Strike. Arousal was measured using Skin Conductance Level (SCL) and aggression using an Implicit Attitude Test (IA...

Objective: In this study, a new training method of working memory (WM) was used in the form of structured games, and the effect of training was evaluated with a controlled design. The training method of WM in the form of structured games includes 20 sets of structured games that can improve WM and performance of executive functions. Method: Sixty children with attention deficit hyperactivity di...

The practical scalability of many optimization algorithms for large extensive-form games is often limited by the games' huge payoff matrices. To ameliorate issue, Zhang and Sandholm recently proposed a sparsification technique that factorizes matrix A into sparser object = Â + UVᵀ, where total combined number nonzeros Â, U, V, significantly smaller. Such factorization can be used in place origi...

There has been increasing interest in using game theory to model real-world systems, and in the computation of game-theoretic solution concepts given such a model [14]. The efficiency of game-theoretic computations depends crucially on how games are represented. For multiagent systems with large numbers of agents and actions, the standard normal form game representation is not a practical optio...

Serious games have proven to be a useful instrument to engage learners and increase motivation. Nevertheless, a broadly accepted, practical instructional design approach to serious games does not exist. In this paper, we introduce the use of an instructional design model that has not been applied to serious games yet, and has some advantages compared to other design approaches. We present the c...

We address the problem of generating complete games, rather than content for existing games. In particular, we try to answer the question which types of games it would be realistic or even feasible to generate. To begin to answer the question, we first list the different ways we see that games could be generated, and then try to discuss what characterises games that would be comparatively easy ...

Challenge and conflict are elements that all game designers strive to engineer into their games. Research shows that challenge is what drives a high proportion of games players yet there are few published tools that can be used to assist the game designer in constructing useful challenges and conflict leading many new game designers to resort to the ‘tried and trusted’ techniques used in previo...

A class of cooperative games is introduced which arises from situations in which a set of agents is hierarchically structured and where potential individual economic abilities interfere with the behavioristic rules induced by the organization structure. These games form a cone generated by a specific class of unanimity games, namely those based on coalitions called peer groups. Different econom...
