groundwater is one of the common resources in varamin plain, but due to over extraction it has been exposed to ruin. this phenomenon will lead to economic and environmental problems. on the other hand, the world is expected to face with more stochastic events of water supply. furthermore, incorporating stochastic consideration of water supply becomes more acute in designing water facilities. th...

in this paper, we analyze the effect of lack of capital investment on energy projects using game theory in the guise of cooperative games. we focus on the energy projects in the provincial level as case study during 2010-2011. therefore, we design a theoretical model of the lack of capital investment as a factor influencing the implement of energy projects. in the experimental section, we deter...

this article aims to study an important principle in discourse analysis, which belongs to paul grice, the contemporary philosopher. he believes that in addition to giving and taking information during a conversation, people also show their cooperation with each other, and so he suggests the ‘cooperative principle’ which contains some principles of subtext. since the cooperative principle is wit...

As teachers are the educational experts, if we want to produce software that is both directly relevant to their needs and can be successfully integrated into the classroom, we need to facilitate a strong co-operative working partnership between the teacher and the software developer. This paper looks at a case study where we create such a partnership and study the consequences. The overall aim ...

Food sharing among nonkin-one of the most fascinating cooperative behaviors in humans-is not widespread in nonhuman primates. Over the past few years, a large body of work has investigated the contexts in which primates cooperate and share food with unrelated individuals. This work has successfully demonstrated that species-specific differences in temperament constrain the extent to which food ...

Abstract A Pd-Co bimetallic alloy encapsulated in melamine-based dendrimer supported on magnetic nanoparticles denoted as ?-Fe 2 O 3 @MBD/Pd-Co was synthesized by a facile co-complexation-reduction method and characterized sufficiently. The catalytic evaluation of showed promising results the Mizoroki–Heck Buchwald–Hartwig amination reactions various iodo-, bromo- challenging chloroarenes aqueo...

Cooperative relaying has shown as promissing approach to improve transmission reliability in cellular network. In this paper cooperative relaying and frequency reuse partitioning are exploited to avoid the co-channel cell interference (CCI) in the downlink multi-cell OFDMA systems. In our system layout, each cell is divided into three regions: the central region, the middle region and the edge ...

Brain can be represented as a network, where regions are the nodes and relations between the regions are edges. Within a network, co-existence of cooperative and competitive relationships between different nodes is called coopetition. Inter-regional genetic influences on morphological phenotypes (cortical thickness, surface area) of cortex display such coopetitive relationships. Here, we have r...

This paper identified and examined saving behaviour and determinants of saving mobilization by the rural co-operators in Southern Tigrai Ethiopia. The input for the study was obtained from randomly selected 120 rural household savers from six purposively selected rural savings and credit cooperatives. The result of the study using least squares method showed that savings mobilized is determined...
