The aim of this study was to characterize the feeding behavior of the Guiana dolphin, S. guianensis, through description and quantification of the strategies used by the dolphins, and possibly to apply this patterns to other areas in its distribution. Data were collected during systematic boat surveys, between November/1996 and May/1997, with 120 hours and 13 minutes of total observations. Sche...

The paper studies the routing in the network shared by several users. Each user seeks to optimize either its own performance or some combination between its own performance and that of other users, by controlling the routing of its given flow demand. We parameterize the degree of cooperation which allows to cover the fully non-cooperative behavior, the fully cooperative behavior, and even more,...

Soccer, association football, is a typical team-game, and is considered as a standard problem of multi-agent system and cooperative computation. We are developing Soccer Server, a simulator of soccer, which provides a common test-bench to evaluate various multi-agent systems and cooperative algorithms. We are working on learning cooperative behavior in multi-agent environment using the server. ...

Objective:The present research aimed to study the relationship of altruistic behavior, empathetic sense, and social responsibility with happiness Methods: This research was a survey, cross sectional and correlational study. Hence, a total of 300 university students were selected through random-stratified sampling from the students of Islamic Azad University. The students filled ...

We propose here an analytical framework to quantify the impact of cooperative diversity on the energy consumption and lifetime of sensor networks. It is well accepted that cooperative diversity increases energy efficiency in fading environments. However, previous works have not analyzed, from a theoretical perspective, these benefits in a network setting. This paper presents a theoretical frame...

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, ...

Joint-stock cooperative company is not recognized in Commercial Code of Iran and the amendment bill of the Commercial Code adopted in 1968. This business entity has a unique description because of both being cooperative and having joint stock. It is a joint-stock company that is chartered based on Commercial Code of Iran, amendment bill of the Commercial Code adopted in 1968, and Principle 44 o...

Predictability may be an important component of cooperative action, or it may arise as a by-product of involuntary entrainment with another's behavior. Further, differences previously observed in cooperative versus competitive actions may represent a fundamental distinction between behaviors with opposite goals, or they may simply reflect the output of different physical actions. The role of pr...

We consider here pure bargaining problems endowed with a coalition structure such that each union is given its own utility. In this context we use the Shapley rule in order to assess the main options available to the agents: individual behavior, cooperative behavior, isolated unions behavior, and bargaining unions behavior. The latter two respectively recall the treatment given by Aumann–Drèze ...
