Aim to analyze the indicators of distortion-product otoacoustic emissions (DPOAE) in persons exposed noise small arms and, on basis most significant them, determine probability developing hearing loss.
 Material and methods. We examined 30 male volunteer shooters (60 ears) aged from 19 years. The fired shots AK74M short bursts (2-3 a burst) at targets when performing shooting exercises thr...

Endpoint admission control solutions, based on probing a transmission path, have been proposed to meet quality requirements of audio–visual applications with little support from routers. In this paper we present a mathematical analysis of a probe–based admission control solution, where flows are accepted or rejected based on the packet–loss statistics in the probe stream. The analysis relates b...

Estimating the cell loss probability in an ATM multi-plexer is a key issue in network management and traac control such as call admission control and bandwidth allocation. In this paper, we derive a new approximation to estimate the total and individual cell loss probabilities in an ATM multiplexer fed by a superposition of heterogeneous on-oo sources with exponentially distributed on and oo pe...

Video transmission over mobile ad-hoc networks is becoming important as these networks become more widely used in the wireless networks. We propose a routing-aware multiple description video coding approach to support video transmission over mobile ad-hoc networks with single and multiple path transport. We build a model to estimate the packet loss probability of each packet transmitted over th...

We can view the prediction problem considered previously as the following: We have m experts and we maintain a vector pt (probability distribution) over the experts and at each round nature reveals loss `t ∈ {0, 1}n. We incur expected loss pt · `t and therefore cumulative loss ∑T t=1 pt· `t. Moreover, in randomized weighted majority we set wi(t+1) = wi(t)(1− ) if i makes an mistake and we choos...

Thick-walled high-pressure vessels are a fairly common type of technical device as part technological equipment operated at various hazardous production facilities. Reliability indicators pressure and their change during operation largely determine the failure-free whole, potential failures subject to consideration when conducting risk analysis operating equipment. The article discusses probabi...

Optical burst switching (OBS) is a promising switching technology for next-generation Internet backbone networks. The main objectives of the dissertation was to provide fairness from various aspects, including rate and distance fairness, to OBS networks without degrading the loss probability or throughput. This dissertation proposes a rate fairness preemption (RFP) scheme to achieve max-min fai...
