A Biomechanical analysis of Javelin Throw in the Sevilla’99 World Athletics Championships , was carried out by the University of Valencia (Department of Physical Education and Sports). This paper presents the results of a study of the male finalists. The methodology used is based on 3D Video Photogrammetry at 50 Hz. The results show the characteristics of the throwers’ individual model at the e...

Nonlinear evolution equations are crucial for understanding the phenomena in science and technology. One such equation with periodic solutions that has applications various fields of physics is Korteweg-de Vries (KdV) equation. In present work, we concerned implementation a newly defined quintic B-spline basis function differential quadrature method solving The results presented using four expe...

Abstract The space inside the capsule such as station sky and core module is narrow, size of depth large, bearing points are scattered weak, there some difficulties in loading, large size, different shape, complicated interface, position, difficult position pose adjustment, high assembly risk, etc.. To solve these problems, a six-DOF heavy-duty robot proposed this paper. adopts combination line...

In this paper we present a practical method for finding obstacle-free minimum-time motions for manipulators subject to the limits of velocity-dependent actuator forces. An optimal motion-planning problem is converted into a finite-dimensional nonlinear programming problem by means of parameter optimization with quintic B-splines. We introduce the concept of the minimum-overload trajectory in wh...

In this paper a finite element method involving Petrov-Galerkin method with quintic B-splines as basis functions and septic Bsplines as weight functions has been developed to solve a general eighth order boundary value problem with a particular case of boundary conditions. The basis functions are redefined into a new set of basis functions which vanish on the boundary where the Dirichlet, the N...

A finite element method involving collocation method with Quintic B-splines as basis functions has been developed to solve fifth order boundary value problems. The fifth order derivative for the dependent variable is approximated by the finite differences. The basis functions are redefined into a new set of basis functions which in number match with the number of collocated points se lected in ...

In our contribution we study cubic and quintic Pythagorean Hodograph (PH) curves in the Euclidean and Minkowski planes. We analyze their control polygons and give necessary and sufficient conditions for cubic and quintic curves to be PH. In the case of Euclidean cubics the conditions are known and we provide a new proof. For the case of Minkowski cubics we formulate and prove a new simple geome...

A finite element method involving collocation method with quintic B-splines as basis functions has been developed to solve tenth order boundary value problems. The fifth order, sixth order, seventh order, eighth order, ninth order and tenth order derivatives for the dependent variable are approximated by the central differences of fourth order derivatives. The basis functions are redefined into...
