background: military personnel are usually exposed to high levels of impulse noise (in) which can lead to hearing loss. objectives: the purpose of this study was to assess the effects of relatively low level exposure of impulse noise (in) during shooting practice on hearing using pure tone audiometry (pta) and transiently evoked otoacoustic emission (teoae) in military personnel. materials and ...

The general aim of the research presented in the present thesis was to elucidate the visual basis of basketball shooting. Chapter 1 provides an overview of the pertinent literature. Previous studies on the topic focused on temporal aspects of vision and identified the rapidity of orienting as necessary ingredients for successful performance and distinguishing marks of expertise. In apparent con...

background and objectives: grape has high nutritional value and it is an economically important horticultural plant in the world. iran has seventh producer grape rank in the world. today tissue culture is one of technique which can be used in grape propagation and breeding. material and method: in order to optimization of callus induction and micropropagation of grape in vitro condition, this i...

BACKGROUND Previous studies using electroencephalography (EEG) to monitor brain activity have linked higher frontal theta activity to more focused attention and superior performance in goal-directed precision tasks. In biathlon, shooting performance requires focused attention after high-intensity cross-country skiing. PURPOSE To compare biathletes (serving as experts) and cross-country skiers...

The aim of our research was to describe the joint angular velocities of young basketball players (U16) during their performance of jump shots and to find out what was the effect of increasing shooting range on these velocities. Our sample included 14 players that performed the function of guards. Their average age (±SD) was 15.43±0.51 years. The analysis contemplated 370 field goals, which were...

Previous research on the relation between working memory capacity (WMC) and shooting behavior suggests that individuals with low working memory spans are more prone to shooting errors than are individuals with high working memory spans. The present study investigated how WMC interacts with the proportion of “shoot” to “don’t shoot” decisions to affect overall shooting performance. Participants ...

Discussion forums are an indispensable interactive component for Massive Open Online Courses (MOOC). However, the organization of current discussion forums is not well-designed. Trouble-shooting threads are valuable for both learners and instructors, but they are drowned out in the forums with huge amounts of threads. This work first built a labeled data set for trouble-shooting thread structur...

We use the idea of the Direct Multiple Shooting Method (presented by H. G. Bock in Proceedings of the 9th IFAC world congress Budapest, Pergamon Press, 1984, for solving optimal control problems) to introduce an algorithm for solving some approximate shortest path problems in motion planning. The algorithm is based on a direct multiple shooting discretization that includes a collinear condition...
