A discrete time multitype (p-type) branching random walk on the real line R is considered. The positions of the j-type individuals in the n-th generation form a point process. The asymptotic behavior of these point processes, when the generation size tends to infinity, is studied. The central limit theorem is proved.

The current importance of energy emphasizes the use of renewable resources (such as wastewater) for electricity generation by microbial fuel cell (MFC). In the present study, the native sulfate-reducing bacterial strain (R.gh 3) was employed simultaneously for sulfurous component removal and bioelectricity generation. In order to enhance the electrical conductivity and provision of a compatible...

social learning and knowledge generation are two key factors to achieve successful natural resources co-management. social learning can be beneficial by broadcasting and transmitting experiences and problem solving ideas in a group of people. social learning networks can transmit knowledge and experiences from one node to another in the network. social learning can produce a suitable learning a...

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...

This paper aims to describe a deterministic generation of extreme waves in a typical towing tank. Such a generation involves an input signal to be provided at the wave maker in such a way that at a certain position in the wave tank, say at a position of a tested object, a large amplitude wave emerges. For the purpose, we consider a model called a spatial-NLS describing the spatial propagation o...

the present paper aims to highlight the origin of the youth movements in iran during the intervening years of 1971 and 2002. during these three decades, youth movement was one of the important social movements in the political arena of the country. while explaining the origin of the movement, two changes i.e. 'generation gap' and 'democracy' have been studied and it was found that the origin of...

In recent years, enriching traditional revenue management models by considering the customer choice behavior has been a main challenge for researchers. The terminology for the airline application is used as representative of the problem. A popular and an efficient model considering these behaviors is choice-based deterministic linear programming (CDLP). This model assumes that each customer bel...
