Performance Improvement

Twelve individuals took part in an experiment which investigated the feasibility of using physiological sensors to apply a pacing mitigation strategy to help prevent cognitive-overload-induced performance declines. The participants performed tasks using a ...

Most research in text classification to date has used a “bag of words” representation in which each feature corresponds to a single word. This paper examines some alternative ways to represent text based on syntactic and semantic relationships between words (phrases, synonyms ...

OBJECTIVES. Our goal was to assess the degree of pediatric preparedness of emergency departments in the United States. METHODS. A closed-response survey based on the American Academy of Pediatrics/ American College of Emergency Physicians joint policy statement, "Care of Chil- dren in the Emergency Department: Guidelines for Preparedness," was mailed to 5144 emergency department medical and nursing directors. A weighted

One purpose of this work was to study the relationship of goal orientations and the perceived motivational climate created by the coach in relation to 219 competitive Spanish tennis players': a) perceived improvement in different facets of the game, b) satisfaction with their competitive results, overall level of play, and coach, and c) ratings of their coach. The second purpose was to examine whether the dependent variables were best predicted by the perceived situationally emphasized goal structure created by the coach and/or the athletes' dispositional goal perspective. Intermediate (N=70), advanced (N=124), and professional (N=25) level players completed Spanish versions of the TEOSQ and the PMCSQ-2 and items assessing perceived improvement specific to tennis, satisfaction and coach ratings. The results were consistent with the tenets of goal perspective theory and provide further support for the promotion of a task involving atmosphere in sport.

The operation of two 60 m2 solar air heaters serving a large studio teaching space has been monitored for a twelve month period. The solar contribution of the heaters was found to be less than 5%, and in some instances the heaters actually contributed to the space heating load. A validated mathematical model of the studio and it's heating, ventilation and air conditioning system was used to investigate performance improvement strategies. It was found a different control strategy and recommissioned control sensors would substantially improve the solar air heater performance. This paper reports the performance of a large solar air heater (SAH) installed on a university building in southern Victoria. The paper begins with a description of the building and the solar air heating system. The methodology used to assess the performance of the solar heating system is described, followed by the results. A validated mathematical model was used to investigate performance improvement strate...

Abstract In this paper, an investigation of the behavior of a recently defined hybrid algorithm for continuous variables electromagnetic optimization problems is presented. This algorithm makes use of the nonlinear simplex method as a principal optimizator, and a greedy genetic algorithm to explore the search space. The algorithm is greatly affected by the tuning of some parameters. Referring to a solenoids system optimal design problem, a detailed comparison of performances obtained implementing a metaheuristic tuning is presented
