this paper studies a maintenance policy for a system composed of two components, which are subject to continuous deterioration and consequently stochastic failure. the failure of each component results in the failure of the system. the components are inspected periodically and their deterioration degrees are monitored. the components can be maintained using different maintenance actions (repair...

Genetic Algorithm (GA), a stochastic optimization technique, doesn’t ensure optimal solution every time. Nowadays there is a need to improve the performance of each and every application so that the time required for obtaining quality solution can be minimized. This paper gives a brief overview of theoretical advances and computing trends, particularly population diversity in PGA (Parallel GA) ...

background and aim: this study investigated whether objective temporal processing paradigms including voice-onset-time, speech-in-noise, and amplitude modulated-broad-band noise (am-bbn) are sensitive to disrupted temporal processing in elderly listeners with normal hearing (age-related-temporal processing deficit). methods: we evaluated 15 adults aged 64–80 years using behavioural measures of ...

The present paper addresses an effective cyber defense model by applying information fusion based game theoretical approaches‎. ‎In the present paper, we are trying to improve previous models by applying stochastic optimal control and robust optimization techniques‎. ‎Jump processes are applied to model different and complex situations in cyber games‎. ‎Applying jump processes we propose some m...

storaging or transmission of speech signals at very low bit rate is a hot area in the field of speech processing. we used stochastic inter-frame interpolators and vector quantization (vq) as a new method for developing a high quality 1200 bps speech vocoder. the objective and subjecgtive test results show that performance of the new vocoder is compairable with 4800 bps standard vocoders (as celp).

Many time-varying phenomena of various fields in science and engineering can be modeled as a stochastic differential equations, so investigation of conditions for existence of solution and obtain the analytical and numerical solutions of them are important. In this paper, the Adomian decomposition method for solution of the stochastic differential equations are improved.  Uniqueness and converg...

In “Dynamic Stochastic Matching Under Limited Time,” Aouad and Sar?taç analyze the design of matching policies in dynamic markets such as carpooling platforms kidney exchange schemes. A crucial distinction with previous literature is that agents’ arrivals departures are fully dynamic. The demand supply side constantly replenished; each market participant remains available for potential matches ...
