Considering a kinematical velocity admissible field, the upper bound method has beenused for predicting the amount of pressure in hydroforming of sheet metals. The effects of workhardening, friction and blank size have been considered in pressure prediction. Also the effect ofsheet thickness variation has been considered in the present work formulations. The relation betweenpressure and punch s...

INTRODUCTION Maximal strength is often estimated using the force-endurance relationship, where tables or formula are used to predict one repetition maximum (1RM) or other loads (e.g. 3RM loads). For some populations (for example the frail or very young) such a procedure may not be appropriate and the accuracy of these methods depends on several parameters such as the number of repetitions, type...

Jidovtseff, B, Harris, NK, Crielaard, J-M, and Cronin, JB. Using the load-velocity relationship for 1 RM prediction. J Strength Cond Res 24(x): 000-000, 2009-The purpose of this study was to investigate the ability of the load-velocity relationship to accurately predict a bench press 1 repetition maximum (1 RM). Data from 3 different bench press studies (n = 112) that incorporated both 1 RM ass...

Distributed applications running on clusters may be composed of several components with very different performance requirements. The FlowVR middleware allows the developer to deploy such applications and to define communication and synchronization schemes between components without modifying the code. While it eases the creation of mappings, FlowVR does not come with a performance model. Conseq...

The vast use of Linear Prediction Coefficients (LPC) in speech processing systems has intensified the importance of their accurate computation. This paper is concerned with computing LPC coefficients using evolutionary algorithms: Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Dif-ferential Evolution (DE) and Particle Swarm Optimization with Differentially perturbed Velocity (PSO-DV...

The article deals with the problem of reliability assessment of complex mechanisms and machines, it is specifically focused on the analysis of the current situation in the field of item reliability prediction. The techniques of the item reliability prediction using the most credible methods (MILHDBK-217F, PRISM) and reliability databases (EPRD-97, NPRD-95) are presented in the article. Also the...
