Customer relationship management -CRM -is a broad term that can cover every mode of customer interaction. This concept has been widely used in business language, enabling companies to gain more knowledge about their customers which, in its turn, can be used to improve marketing and sales targeting, improving their results. University and research institutions (URIs), as any other organizations, also need to cater to the needs of their clients, which may be: society in general, their students, researchers and collaborators; other institutions -of a research or commercial nature with which they interact (supplying data, results from research work, consultancy work, and the execution of partnerships) -or governments that make use of their teaching practices and results from their research work. So, this work is a CRM proposal for URIs, studying the differences between the academic/scientific and business world and proposing an environment to manage all kinds of relationships in the academic and scientific scenario.

In multi-agent systems, blackboard communication provides an easy way for agents to communicate. However, in a distributed architecture, the blackboard is commonly implemented in a single node, that is the "blackboard server". This approach may work well for a small number of agents. Nevertheless, when the number of agents increases, the blackboard server becomes the bottleneck for the system scalability. In this work we propose a novel agent communication system based on distributed-shared mechanisms that allows the implementation of a shared address space on a distributed system, without centralizing the blackboard. Our idea is to distribute the shared data over the nodes and use a message passing sub-system, totally transparent to the agents. We implemented this idea in a multi-agent system based on social laws, and used a distributed-shared memory system to handle the messaging. We created a conflict simulator, and showed that the distributed-shared mechanisms easy the implementation of a truly distributed blackboard.

The Broadband Wireless Access (BWA) technology has been proposed to support different traffic classes with distinct quality of service (QoS) requirements in broadband metropolitan area networks. Therefore, as part of its specifications, such a system must properly address the combined requirements of wireless communications and multimedia applications. We propose in this paper an extension to the MAC protocol presented in [1, 2], by assigning variable priorities to the network stations sharing access to the communication channel. An analytical model to evaluate the performance of the proposed protocol is also developed and results obtained for the messages waiting times at different stations are presented. In addition, simulation data are used to compare the results obtained from the analytical model presented previously. It is concluded that the proposed variable priority MAC protocol is able to improve channel utilization and provide throughput and queueing delay fairness among the stations in the network.

Software systems are growing quickly in needs of functionality, complexity, size and structure. Therefore, it becomes necessary to advance the ways where the software suffers changes, so it can be modified more easily to accommodate these needs. However, anticipating to the changes is not an easy task, once there are a lot of reasons why systems change. The Laws of Software Evolution describe how a system behaves throughout their successive versions regarding its decaying. Most of the experimental studies supporting these Laws are concerned with legacy systems' source code. However, we believe the Laws can also be observed and applied when dealing with other software development process phases, including evolutive maintenance. Therefore, we present a set of hypotheses to experimentally verify whether the Laws of Software Evolution can also be observed in the object-oriented software. A case study demonstrating the framework's use is also described.
