Hierarchies are present everywhere (physics, medicine, nature, human needs, etc.) and tennis is no exception. Is counterpuncher's goal just to chase down every ball and force the opponents into long rallies? The aim of this first empirical study is integrate theory and practice about overall quality evaluation and accurately analyze offensive and defensive tennis priorities for counterpunchers....

The procedural steps for developing an expert system for designing signals at isolated intersections are described and the most important development issues for each step are discussed. The steps include problem analysis and definition, preliminary prototype specification, knowledge acquisition strategy development, prototype development plan, knowledge extraction, knowledge representation, too...

Introduction: Hospitals performance indicators will help monitoring, evaluation and decision making and therefore must be selected and ranked accurately. The aim of the present study is to identify and to select key hospitals performance indicators. Materials and Methods: This is a quantitative-qualitative study in which literature review and expert panel has been done to identify all performan...

The development of expert systems using parallel machines is a practice in its infancy, but its future is very promising. Researchers at the Artificial Intelligence Laboratory of the C.M.R. de Saint-Jean have been able to implement a cooperative system in which relatively independent agents cooperate to solve a specific problem. The system presented is implemented on a distributed memory parall...

There were two main objectives of this research. First, we wanted to examine whether video feedback of the self (self-observation) was more effective for motor skill learning when the choice to view the video was provided to the learner (learner-controlled, LC) as opposed to an experimenter-controlled (EC) delivery. Secondly, we explored whether there were differences in the self-regulatory pro...

A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...
