abstract climate change means a significant change in the long-term weather of a region in comparison with what has been observed during a long term period. precipitation and minimum and maximum temperature are three variables which are affected directly by the climate change. furthermore, the water yield of a river is one of the most important hydrological variables of a basin which is affecte...

since the emergence of power market, the target of power generating utilities has mainly switched from cost minimization to revenue maximization. they dispatch their power energy generation units in the uncertain environment of power market. as a result, multi-stage stochastic programming has been applied widely by many power generating agents as a suitable tool for dealing with self-scheduling...

Rate outage probability is an important performance metric to measure the level of quality of service (QoS) in the Generation (4G) broadband access networks. Thus, in this paper, we calculate a closed form expression of the rate outage probability for a given user in a down-link multi-hop OFDMAbased system encountered as a result of links’ channel variations. The channel random behavior on diff...

in this paper, a new framework has been developed for compatibility analysis of predictive climatic variables distribution with reference evapotranspiration (eto) in probabilistic analysis of water requirement. initially, measured monthly meteorological data of four cities of iran including kerman, shiraz, ramsar and babolsar synoptic weather station recorded from 1961 to 2003 were considered b...

In the paper a finite-capacity discrete-time queueing system with geometric interarrival times and generally distributed processing is studied. Every time when service station becomes idle it goes for vacation of random duration that can be treated as power-saving mechanism. Application single policy one way to achieve symmetry in terms operating costs. A differential equations transient condit...

This paper introduces the concept of a random variable, which is nothing more than a variable whose numeric value is determined by the outcome of an experiment. To describe the probabilities that are associated with these numeric values in a concise and conceptually useful manner, the probability distribution and probability density function are introduced. Then, the moment generating function ...

We propose an exact method for generating random deviates from continuous order statistics. This versatile method that generates Beta deviates as a middle step can be applied to any density function without resorting to numerical inversion. We also conduct an exhaustive investigation to document the merits of our method in generating deviates from any Beta distribution.

The problems of the first-passage time (FPT) [1, 2] and the residence time (RT) [3] are very important issues in random walk theory. Moreover, several properties of diffusion and transport in disordered systems are based in this concepts. Here, we do not want to present a survey of the enormous literature in the field of mean firstpassage time (MFPT) and mean residence time (MRT) of random walk...
