Objectives: To examine the relationship between task and ego orientations and the use of stress-coping strategies among athletes participating in the 1994 Winter Olympic Games. We expected that athletes who were high on task and low on ego orientation would employ more problem-solving strategies than athletes with other ego and task profiles. We also expected that athletes high in ego and low i...

This study evaluates the feasibility of using the grass species Rendlia altera, Monocymbium ceresiiforme, Cynodon dactylon, and amendments (compost and lime) for the phytostabilisation of soils contaminated by Cu in the province of Katanga (Democratic Republic of Congo). Species were grown on control and Cu-contaminated plots (artificially contaminated with 2,500 mg kg(-1) Cu) unamended (NA), a...

In many aerospace engineering design problems, objective function evaluations can be extremely computationally expensive, such as the optimal design of the aerodynamic shape of an airfoil using high-fidelity computational fluid dynamics (CFD) simulation. A widely used approach for dealing with expensive optimization is to use cheap global surrogate (approximation) models to substitute expensive...

Résumé. Cet article présente une méthode complexe pour la caractérisation et l’indexation d’images graphiques de documents anciens. A partir d’un bref état de l’art, une méthode pour décrire ces images en tenant compte de leur complexité est proposée. Trois étapes principales de ce traitement sont détaillées dont une méthode novatrice d’analyse, de segmentation et de description des traits. Les...

FPGA users are constantly looking for ways to differentiate their products in the market place and in doing so they define new systems with new requirements. The new requirements usually are increased functionality, higher processing performance, low power consumption, customizable capabilities, and reprogrammability. To achieve these requirements, the proven methodology is to double the FPGA d...
