Background. Kinanthropometric and Kinematic variable are important in the understanding of performance in various sports. These variables have not been explored among Tennis players in Nigeria. Objectives. An exploration to establish a regression model for kinanthropometric and kinematic variables in relation to ball velocity of Nigerian Female Tennis Players. Methods. Data were collected thr...

The present work proposes a method for human gait and kinematic analysis. Gait analysis consists of the determination of hip, knee and ankle positions through video analysis. Gait kinematic for the thigh and knee is then generated from this data. Evaluations of the gait analysis method indicate an acceptable performance of 86.66% for hip and knee position estimati...

The stability analysis of rock slopes is a complex task for the geotechnical engineers due to the complex nature of the rock mass in a tropical climate that often has discontinuities in several forms, and consequently, in several types of slope failures. In this work, a rock mass classification scheme is followed in a tropical environment using the Rock Mass Rating (RMR) and Geological St...

This paper presents workspace and kinematic analysis of a parallel machine based on the Lambda mechanism. The considered has six degrees freedom (DOF), achievable with actuated translation joints. includes definition every active part machine, as well or passive joint used to connect parts. mathematical model is created for better understanding machine's operation. proposed inverse equations, w...

The author presents an interesting method to forecast nonlinear kinematic flood waves (Serrano, 2006). As a first remark, the discussers would like to stress the fact that the proposed method is an approximate solution and not an analytical solution, as suggested by the title of the paper. Indeed, an analytical expression is given by the backwards characteristics methods, as in Eq. (6) of the p...

We propose a model for learning the articulated motion of human arm. The goal is to generate plausible trajectories of joints that mimic the human movement using deformation information. The trajectories are then mapped to constraint space. These constraints can be the space of start and end configuration of the human body and task-specific constraints such as avoiding an obstacle, picking up a...

We review coherent scattering of neutrinos on nuclei by coupling the weak currents to vector and axial-vector meson states. The couplings are obtained from known reactions, like τ –lepton and vector meson decays. We compute and present the cross sections as functions of energy and momentum transfer for various kinematic regions, including those which are relevant to oscillation experiments. The...
