Background. Archery is a precision sport that requires high levels of consistency and reproducibility in the shooting movement to achieve the highest score. Objectives. This study aimed to compare and correlate the shooting time characteristics and shooting posture on the archery shooting performance of high- and low-performance archers. Methods. Terengganu state team and Malaysia Pahang Spor...

the main purpose of this paper is to introduce a boundary layer analysis for the fluid flow andheat transfer characteristics of an incompressible nanofluid flowing over a permeable isothermalsurface moving continuously. the resulting system of non-linear ordinary differential equations issolved numerically using the fifth–order runge–kutta method with shooting techniques usingmatlab and maple s...

Estimating the parameters of a dynamical system based on measurement data is an important but complex task in industrial and scientific practice (Schittkowski, 2002). Due to its importance, different approaches to solve this kind of problem have been developed. The most established ones are single shooting (Bard, 1974), multiple shooting (Bock, 1983) and full discretization techniques (Biegler,...

We consider the problem of ray shooting amidst spheres in 3-space: given n arbitrary (possibly intersecting) spheres in 3-space and any " > 0, we show how to preprocess the spheres in time O(n 3+"), into a data structure of size O(n 3+"), so that any ray-shooting query can be answered in time O(n "). Our result improves previous techniques (see 3, 5]), where roughly O(n 4) storage was required ...

This paper investigates spatial and visual analytics as means to enhance basketball expertise. We introduce CourtVision, a new ensemble of analytical techniques designed to quantify, visualize, and communicate spatial aspects of NBA performance with unprecedented precision and clarity. We propose a new way to quantify the shooting range of NBA players and present original methods that measure, ...

Geometrically nonlinear forced vibrations of three dimensional structures, due to harmonic excitations, are investigated in the frequency domain. Structures of elastic materials are considered and the discretized equation of motion is derived by the finite element method, using Elmer software. The shooting and the continuation methods are applied to the resulting large scale FEM system by using...
