this paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. system engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (tco...

The purpose of this study is to construct a model that predicts an aquifer’s formation strength index (the ratio of shear modulus and bulk compressibility, G/Cb) from geophysical well logs by using a backpropagation neural network (BPNN). The BPNN model of an aquifer’s formation strength index is developed using a set of well logging data. The model is a [4-5-1] three-layer BPNN with a four-neu...

BACKGROUND Grip muscle force has always been used to assess functional limitations in elderly. Its use as a tool to assess work capacity has never been described in the literature. OBJECTIVE To describe the patent determinants of grip strength and the usefulness of its measurement in assessing workability index in the healthcare sector. METHODS This is a cross-sectional study conducted in a...

PURPOSE To determine the reliability and variability of the Dynamic Strength Index (DSI) calculated from squat-jump (SJ) vs countermovement-jump (CMJ) peak force (PF) and to compare DSI values between methods. METHODS Male youth soccer and rugby league players (N = 27; age 17.2 ± 0.7 y, height 173.9 ± 5.7 cm, body mass 71.1 ± 7.2 kg) performed 3 trials of the SJ, CMJ, and isometric midthigh p...

BACKGROUND It is well documented that cigarette smoking has negative impacts on body health, as well as social health, economy, culture, etc. Nowadays, there is a large body of evidence that smoking is the cause of numerous life-threatening diseases like cardiovascular and pulmonary diseases along with different kinds of cancer. The aim of this study was to compare the physical fitness of smoke...
