Most previous works study the evolution of cooperation in a structured population by commonly employing an isolated single network. However, realistic systems are composed of many interdependent networks coupled with each other, rather than the isolated single one. In this paper, we consider a system including two interacting networks with the same size, entangled with each other by the introdu...

We study the phenomenon of evolution of cooperation in the electricity domain, where self-interested agents representing distributed energy resources (DERs) strategize for maximizing payoff. From the system’s viewpoint cooperation represents a solution capable to cope with the increasing complexity, generated by the introduction of DERs to the grid. The problem domain is modelled from a multi-a...

Cooperation among nodes is fundamental for the operation of mobile ad hoc networks (MANETs). In such networks, there could be selfish nodes that use resources from other nodes to send their packets but that do not offer their resources to forward packets for other nodes. Thus, a cooperation enforcement mechanism is necessary. Trust models have been proposed as mechanisms to incentive cooperatio...

Theoretical studies of cooperative behavior have focused on decision strategies, such as tit-for-tat, that depend on remembering a partner’s last choices. Yet, an empirical study by Stevens et al. (2011) demonstrated that human memory may not meet the requirements that needed to use these strategies. When asked to recall the previous behavior of simulated partners in a cooperative memory task, ...

the encyclopedia of islam (leiden) is one of the most important / out–standing appearance of a descriptive–historical or phenomenon–logical attitude to the western islamic studies. also it is considered the symbol of specialization in the studies. since history, culture and civilization of iran pre /after islam) and shi, ism are among the important topics of islamic studies, we show that how th...

We show that the available constraints relating to LiBeB Galactic evolution can be accounted for by the so-called superbubble model, according to which particles are efficiently accelerated inside superbubbles out of a mixture of supernova ejecta and ambient interstellar medium. The corresponding energy spectrum is required to be flat at low energy (in E below 500 MeV/n, say), as expected from ...

Density waves in the central kpc of galaxies, taking the form of spirals, bars and/or lopsided density distributions, are potential actors of the redistribution of angular momentum. They may thus play an important role in the overall evolution of the central structures, not mentioning the possible link with the active/non-active central mass concentration. I present here some evidence for the p...

In this paper we would like to propose a Janus head perspective on cooperation and models: on the one hand cooperation on models is a very important type of activity for groups who want to create shared models that are accepted by the group members; on the other hand models for cooperation are an essential basis to develop user-centred cooperative systems.

In each time period, the demand of passengers for each route are finite and airlines compete for earning more profits. The complex competition among airlines causes problems, such as complicating flight planning and increasing empty seats for some routes. These problems increase air pollution and fuel consumption. To solve these problems, this research studies the cooperation of the airlines wi...

Due to the diversity of interpretations and definitions given in Latin America to the terms gobernabilidad and gobernanza, this paper brings together and compares these definitions with the concepts of the Anglo-Saxon terms: governance and governability. After an anthropological analysis of these concepts, it proposes a definition of governance which could be applied in international cooperatio...
