Due to emerging real-time and multimedia applications, efficient routing of information packets in dynamically changing communication network requires that as the load levels, traffic patterns and topology of the network change, the routing policy also adapts. We focused in this paper on QoS based routing by developing a neuro-dynamic programming to construct dynamic state dependent routing pol...

In this paper, we propose a model of aerial pollution of an urban area, the city of Ouagadougou. We develop a mathematical model of the spatial area from the pollution point of view. This model is based both on the concept of pretopological structure and the concept of random sets. The reader who is not familiar with pretopological concepts can find out all he needs on the 2 Studia Informatica ...

This paper introduces design principles of serious games which goal is to understand the player/learner decision process. The analytical dimension is the core of gameplay questions: what are the mechanics able to make the player aware of his behavior as a decision-maker? This research questions the video game as a tool to develop the reflexivity and put in perspective the decision-making of the...

The large amount of information and the increasing complexity of applications constrain developers to have stand-alone and reusable components from libraries and component markets.Our approach consists in developing methods to evaluate the quality of the software component of these libraries, on the one hand and moreover to optimize the financial cost and the adaptation’s time of these selected...

Workflow and Service Oriented Architectures (SOA) favor collaboration among business partners and promote the development of flexible and efficient collaborative applications. This paper proposes an approach to connect workflows of several partners using services for modeling inter-organizational processes particularly built according to a “case transfer” form of cooperation. The "case transfer...

Within the framework of the information retrieval, the restitution of the documents is carried out according to their calculated relevance score. They correspond to a precise request. However questions arise as for the representation of documents and requests like their mapping. The graph is used as data visualization, without requiring mathematical knowledge. This article presents the contribu...

In this paper, we present an unsupervised grouping approach of data items (images) in the context of content-based exploration of large image databases. More particularly, we highlight a partition clustering method, which proposes an experimental solution to the famous problem of automatic discovery of the number of clusters (k). The majority of partition clustering methods consider the manual ...

For more than 20 years, many countries have been trying to set up a standardized medical record (regional or national). Most have not reached this goal, essentially due to two main difficulties related to patient identification, and the standardization of medical records. We propose here the non-centralized management of medical records relying on a specific procedure that gives the patient acc...
