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 ...

in a military organization, the role of transportation should be much more strong and strategic character for the organization. in this context, the evaluation of operating ability of transportation and eliminate defects and problems, can help the managers to improve performance and increase the effectiveness and efficiency of transportation in the assigned missions. in this study, a model is p...

Doctors performing brain surgery by flashlight during a blackout necessitated by a Japanese air raid. The austerity of the surroundings is evident in the lack of medical equipment and supplies. Just as the wounded soldier moves along a pathway from injury, to triage, to care, to recovery, military physicians need to travel along their own pathway of understanding themselves as both physician an...

We study a repairable item inventory system under limited repair capacity and nonstationary Poisson demands, motivated by corrective maintenance of military equipment. Our goal is to minimize the cost of both spare and repair resource allocation. We propose an efficient analytical model that combines optimization modeling and queuing theory.

Today, engineering structures have wide application in military equipment, industrial equipment, machines, robots, etc. How to make the engineering structures away from many damages, repairs, and other costs and how to control them in a way that their life reduction would be prevented are challenging problems for researches in recent decades. They are trying to find an appropriate control appro...

Digital signal processing (DSP) underpins modern wireless and wireline communications, medical diagnostic equipment, military systems, audio and video equipment, and countless other products, becoming increasingly common in consumers' lives. Due to advances in semiconductor technology, ever more complex DSP algorithms, protocols, and applications are now feasible, which, in turn, increase the c...

Russia's attack on Ukraine provoked a reaction from Western states, which jointly pledged to provide aid the fighting Ukraine. The attitude of countries is very important in terms Ukraine's independence. Military support, despite its large scale, probably insufficient for Armed Forces are now completely dependent supply weapons, military equipment and other materials countries. Ukrainian army c...

Accurate capture of encumbered anthropometry is critical to ensure that the analysis and design of military platforms and workspaces account for the additional space required for clothing and PPE equipment. To examine the effect of encumbrance on spatial claim, a method was developed to obtain scan-extracted measures from detailed whole-body shape data. This analysis focused on comparing cross-...

In this paper, we model the method in which aircraft survivability equipment suites successfully choose their countermeasures, and experiment with their autonomous decision-making against threats in various electronic warfare settings. We have designed and implemented our simulators to estimate the operational effectiveness of the aircraft survivability equipment suite. We formulate the operati...
