In wireless communication networks, when the workload increases, sources become more aggressive at the equilibrium in the game setting in comparison with the team problem by using slotted Aloha mechanism. Consequently, more packets are in collision and are lost. To reduce these phenomena and to enhance the performance of the networks, we propose to combine ZigZag decoding approach with non coop...

Mainly due to an enforced legislation as well as an increased social demand, companies need to integrate ecological aspects into their corporate goals. Compliance to these goals often leads to the development of innovative approaches to environmental management by means of applying the fundamental principles of the “Circular Economy”. Additionally, intra and inter-organizational concepts of was...

In this paper we present modeling, analysis and synthesis of visual behaviors of agents engaged in navigational tasks. We consider situations in which two agents can navigate independently or in cooperation. For the purpose of modeling the behaviors we have adopted a formalism from the Discrete Events Systems (DES) theory, suitable for investigating controltheoretic issues of a system. Our cont...

* From Kyng & Mathiassen (1997). Computers and Design in Context. pp. 201-238. This chapter represents a step towards the establishment of a new system development approach, called Cooperative Experimental System Development (CESD). CESD seeks to overcome a number of limitations in existing approaches: specification oriented methods usually assume that system design can be based solely on obser...

This paper studies Bayesian equilibrium in a worker firm matching problem in which workers choose their human capital investment and firms choose wages before the matching process occurs. Symmetric equilibrium exists, and supports assortative matching. When the number of traders is large, the highest types invest efficiently, while low types invest too much and receive wages that are too high i...

In order to increase enterprise performance, economics paradigms focus, now more than ever, on how to better manage information. The modern architecture of information systems is based on distributed networks with a grand challenge representing and sharing knowledge managed by those ISs. One of the main issues in making such heterogeneous Cooperative Information Systems (CIS) working together i...

Sign languages can be learned effectively only with frequent feedback from an expert in the field. The expert needs to watch a performed sign, and decide whether the sign has been performed well based on his/her previous knowledge about the sign. The expert’s role can be imitated by an automatic system, which uses a training set as its knowledge base to train a classifier that can decide whethe...

A b s t r a c t In this paper, we briefly discuss the dynamic and functional approach to computer symbolic tensor analysis. The ccgrg package for Wolfram Language/Mathematica is used to illustrate this approach. Some examples of applications are attached.

In this article, we propose a fuzzy class relation assigning to each pair of finite fuzzy sets a degree to which they are equipollent, which indicates that they have the same number of elements. The concepts of fuzzy sets and fuzzy classes in the class of all countable sets are introduced, and several standard relations and constructions, such as the fuzzy power set and exponentiation, are defi...
