Abstract
Recently there has been a growing interest by the sports' community (educators and coaches) in analyzing efficiently the performance of handball players and teams. The information collected from such analysis is used to better understand the difficulties of trainees, players or even entire teams and formulate adequate training and strategic plans. Usually this evaluation is too self contained and does not explore the many tools there are available nowadays. This paper proposes a simulation tool to tackle this problem and establishes the bases for a Handball Sport Simulator. The simulator developed has its origins on the Soccer Server simulator used on the RoboCup competition and includes the main handball game rules and player actions. This paper establishes the ground foundations for a Handball Simulator and results show that the handball rules and actions can be modeled.

Abstract
This paper presents a case study of an existing web application of inventory management for electronics laboratories, accounting for usability principles and best practices for user interface design. The iLab project efficiently manages the inventory, requests, users (borrowings, purchases, etc.) and associated historic and workflow information. This enables users to queue requests and track their statuses. Usability is critical for for the success of such application. A web based interface is to be designed using usability principles, making sure all end-users use the application in an intuitive and effective way. To achieve these goals the study consisted on four phases: plan, analyze, design and, test and refine. After this study it has been concluded that with this methodology developers are able to create more user-friendly and efficient applications.

Abstract
The constant search of industry for productivity raises and market shares, pushes forward the development of new products capable of giving an answer to these concerns. Specifically the tool-machines makers have tried to solve these problems incrementing the capability of the machines they produce, essentially in speed and precision. The recent study of some problems associated to the machining process, has revealed the possibility of incrementing the productivity of some of vertical milling machine, only through the force control, keeping it constant and equal to the optimum value defined for the tool. The cutting force control, due to the system characteristics, can only be implemented by making use of adaptive control. In order to implement adaptive controllers we have at our disposal two technologies that have been showing good results. These technologies are Neural Networks and Fuzzy Logic. We thought that it would be of interest to research the use of Artificial Neural Networks in implementation of a controller. This has been the objective for the development of the work described in this paper. The results obtained have been encouraging, showing the possibility of implementing those controllers in real systems.

Abstract
An innovative software called FEUP Fuzzy Tool was developed by professor and students as a teaching tool to support the control of non-linear systems using the computational resources available. It is based on the theory of Fuzzy Logic control. The tool is currently used for investigation and educational purposes. This document briefly describes and validates through some example applications the current release of the toolbox which makes it one of the most complete and advanced fuzzy logic software available. The present tool now includes Neuro Fuzy optimization, visual debugging and run time control on the PC or in an embeddable platform.

Abstract
The goal of this paper is to discuss the usage of distributed architecture for the Lego NXT robots. This platform is very interesting because it provides standard hardware for configurable mounting of several sensors and actuators. The presented work characterizes sensors and actuators and identifies limitations of the stand-alone architecture. In order to maximize usefulness and go beyond the identified limitations, a distributed computing architecture was developed that allows the Lego NXT to address complex missions. The distributed architecture makes use of two different programming environments. The described architecture was tested in a sample self localization task.

Abstract
This paper presents a case study of a web application for inventory management of electronics laboratories. The iLab project efficiently manages the inventory, requests, users (borrowings, purchases, etc.) and associated historic and workflow information. This enables users to queue requests and track their status. This project differs from the existing applications from this kind, since it not only serves administrative proposes, but also the users requirements. It was also developed with tools that ensure ease of development and deployment, while maintaining high performance, stability, security and future growth. In order to ensure a low "Total Cost of Ownership" application, freeware and web based tools were used. Future work includes Business to Business communications with large suppliers and optimization of the information stored in the database.
