Radiation therapy, an increasingly available and effective cancer treatment solution, involves sophisticated machinery as well as careful planning. Interactive 3D simulations combined with accurate 3D patient specific data can improve the planning process saving time and resources in generating the optimal treatment plan. We illustrate the potential of X3D in radiation therapy, specifically rad...

Considering the benefits of preparation for writing in the pre-writing phase, this study attempted to examine the effects of different pre-task strategic planning activities (i.e., pre-task form-focus planning, content-focus planning, and no planning) on writing accuracy and motivation. To achieve the objectives of this study, sixty intermediate EFL learners were selected from an English langua...

Currently a standard technique to compute the heuristic in heuristic planning is to expand a planning graph on the relaxed problem. This paper presents a new approach to expand the planning graph, such that heuristic estimations are more accurate when an optimization metric criteria is given. Additionally, a new kind of Hill-Climbing search that combines two heuristics is proposed to deal with ...
