The aim of this work is to present a data mining application to software engineering. We describe the use of data mining in some parts of the design process of a dynamic decision support system agent-based architecture. The main function…

This thesis describes the development and experimental verification (via liquid state nuclear magnetic resonance techniques) of new methods for controlling open quantum systems. First, methods that improve coherent control through the use of both strong control fields and detailed knowledge…

Conversational interfaces have received much attention as a promising natural communication channel between humans and computers. A typical conversational interface consists of three major systems: speech understanding, dialog management and spoken language generation. In such a conversational interface, speech recognition…

Most neural network learning algorithms cannot use knowledge other than what is provided in the training data. Initialized using random weights, they cannot use prior knowledge such as knowledge stored in previously trained networks. This manuscript thesis addresses this problem.…

Chapter 1. Molybdenum Dinitrogen Chemistry: Formation and Reactivity of (Ar[tBu]N)3MoN2- A collection of (Ar[tBu]N)3MoN2- compounds, supported with Na+, K+, Mg2+ and Ca2+ have been prepared through a variety of synthetic routes. In several experiments, N2 was replaced with other small…

Multi-agent systems (MAS) offer an approach to solve complex problems where data and control are inherently distributed among several agents. Normally, agents have to cope with conflicts based on inconsistent knowledge which arise when they exchange information. A relative common…

O câncer de colo uterino constitui um problema de saúde pública em nosso país. A literatura evidencia a prevenção por meio de ações de educação em saúde e conscientização da população. A pesquisa investigou o conhecimento das mulheres sobre prevenção…

Recent research has identified an extended exchange network in the Japan Sea Rim area extending over 3,000 km and including the mainland. This paper reviews current knowledge about obsidian studies in Hokkaido, a part of this region, and makes proposals…
