This study gives the reliability analysis of bearing capacity of large-diameter piles under osterberg test. The limit state equation of dimensionless random variables is utilized in the reliability analysis of vertical bearing capacity of large-diameter piles based on Osterberg loading tests. And the reliability index and the resistance partial coefficient under the current specifications are c...

The difficulty of real-time muscle force or joint torque estimation during neuromuscular electrical stimulation (NMES) in physical therapy and exercise science has motivated recent research interest in torque estimation from other muscle characteristics. This study investigated the accuracy of a computational intelligence technique for estimating NMES-evoked knee extension torque based on the M...

Abstract: In this paper, a combined use of dimensional analysis (DA) and statistical design of experiments (DOE) is proposed for a hydrodynamics experiment where there are a large number of variables. While DA is well-known, DOE is still unfamiliar to most ocean engineers although it has been shown to be extremely useful in many engineering applications. To illustrate the method, a study concer...

Load-dependent power loss is a major contributor to power loss in gear transmission systems. In this study, pin-on-disc frictional and FZG efficiency experiments were conducted with powder metallurgy (Distaloy AQ ? 0.2 %C) and wrought material (16MnCr5) combinations. The gear mesh torque loss from gear efficiency tests and the friction coefficient from the pin-on-disc tests were then compared. ...

This paper describes experimental and numerical procedures to estimate friction torque on a rotating shaft due to radial elastomeric seals. Two different test rigs have been built, in order to highlight the relationship between the overall friction and the local behaviour of each lip portion in presence of dynamic eccentricities. A direct measurement has been performed with a rotating shaft mac...

Background. It has been long believed that Parkinsonian rigidity is not velocity-dependent based on the neurological examination. However, this has not been verified scientifically. Methods. The elbow joints of 20 Parkinson's disease patients were passively flexed and extended, and two characteristic values, the elastic coefficient (elasticity) and the difference in bias (difference in torque m...

Several approaches to quantum gravity (including the model of superplastic vacuum; Diakonov tetrads emerging as bilinear combinations fermionis fields; BF-theories gravity; and effective acoustic metric) suggest that in general relativity metric must have dimension 2, i.e., [g??] = 1/[L]2, irrespective spacetime. This leads “dimensionless physics” discussed [1]. Here we continue exploit this un...

The purpose of the study was to determine the effect of bed rest with or without strength training on torque fluctuations and activation strategy of the muscles. Twelve young men participated in a 20-day bed rest study. Subjects were divided into a non-training group (BRCon) and a strength-training group (BRTr). The training comprised dynamic calf-raise and leg-press exercises. Before and after...
