BACKGROUND Impulse noise produced from firearms can potentially damage hearing organs resulting in sensorineural hearing loss (SNHL). In Chiang Mai during 1997, Detphithak et al reported a prevalence of acute acoustic trauma (AAT) in 22% of new military privates using an H.K.33 for shooting practice without hearing protection. The H.K.33 renders an average sound pressure level of 128 dBA. Earmu...

Background and Aim: High quality, fast-paced and cost-effective training of novice military personnel is a major concern in most armed forces around the world. Hence, implementing psycho-technological findings is important in the armed forces. This study aimed to investigate and compare the efficacy of brain-training (neurofeedback) and virtual-reality training through the use of actual and vir...

A steel plate material Hardox can be used also as a core design material for the production of ballistic barriers or traps at the shooting ranges for small arms. The article deals with the results of experiments with shooting weapon systems of a high ballistic performance and with Finite Element Method simulation of the projectile penetration upon the steel plate using the software Ansys Autody...

The authors have applied reinforcement learning methods to real robot tasks in several aspects. We selected a skill of soccer as a task for a vision-based mobile robot. In this paper, we explain two of our method; (1)learning a shooting behavior, and (2)learning a shooting with avoiding an opponent. These behaviors were obtained by a robot in simulation and tested in a real environment in RoboC...

Rectilinear Binary Space Partitioning (BSP) trees are often used for solving various types of range searching problems including ray shooting. We propose a novel method for construction of rectilinear BSP trees for a preferred set of ray shooting queries. Particularly, we study ray sets formed by fixing either the direction or the origin of rays. We analyse and discuss the properties of constru...

this work concerns the peristaltic flow of a williamson fluid model in an inclined asymmetric channel under combined effects of heat and mass transfer. the governing nonlinear partial differential equations are simplified under the lubrication approach and then solved analytically and numerically. the analytical results are computed with the help of regular perturbation and the numerical result...

Abstract. Numerical solutions of exact controllability problems for linear and semilinear 2-d wave equations with distributed controls are studied. Exact controllability problems can be solved by the corresponding optimal control problems. The optimal control problem is reformulated as a system of equations (an optimality system) that consists of an initial value problem for the underlying (lin...

We propose a novel method for construction of rectilinear BSP trees for ray shooting acceleration. The trees are contracted according to certain “preferred” set of rays. Particularly, we study ray sets formed by fixing either the direction or the origin of rays. The constructed trees can be used to answer ray shooting query for arbitrary rays, although with higher expected time complexity for r...
