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...

the purpose of the present research was to study the effect of cooperative methodology on the social skill development of the primary students. the methodology was quasi-experimental, with pre-test, post-test, and control group. the population of the research was all 486 ‘laleh’ primary school male students in the year of 2009-2010, among whom, 61 four-grade participants were finally chosen. th...

Cooperative advertising is a cost-sharing mechanism in which a part of retailers' advertising investments are financed by the manufacturers. In recent years, investment among advertising options has become a difficult marketing issue. In this paper, the cooperative advertising problem with advertising options is investigated in a two-period horizon in which the market share in the second period...

Cognitive radio (CR) enhanced vehicular ad hoc network (CR-VANET) is a special VANET that each vehicle could explore local spectrum gap and reduce data congestion by mitigating interference by dynamically accessing spectrum holes. One of the most important challenges for CR-VANET is to identify the presence of primary users (PU) over wideband spectrum at a particular time and specific geographi...

Pharmacologic and toxicologic responses to new agents can be greatly influenced by a number of factors, including background genetic variability. The refinement of rodents through breeding of known strains has provided a supply of genetically homogeneous animals that yield consistent responses to the challenges of new agents. Some rodent animal models are selected based upon their well-understo...

In order to effectively evaluate the cooperative efficiency of intelligent transportation facilities, a structural model four development elements, including functional cooperative, operational information and operation is constructed with guidance system coordination evaluation established based on it. Then, dynamic variable weight matter-element extension method was describe facilities analyz...

In this paper, ant colony optimization (ACO) algorithms are proposed for reservoir operation. Through a collection of cooperative agents called ants, the near-optimum solution to the reservoir operation can be effectively achieved. To apply ACO algorithms, the problem is approached by considering a finite horizon with a time series of inflow, classifying the reservoir volume to several interval...
