Natural language understanding systems require a knowledge base provided with formal representations reflecting the structure of human beings' cognitive system. Although surface semantics can be sufficient in some other ...

In this book, we address landscape architecture, from composition and construction, from the visual and the tectonic, from form and matter. With this, it is intended to configure a basic manual for the student who delves...

Self-optimizing mechatronic systems react autonomously and flexibly to changing conditions. They are capable of learning and optimize their behavior throughout their life cycle. The paradigm of self-optimization is origi...

Within the context of multi-agent systems, an agent may often ¯nd itself in a position where it receives information through informants. These informants are independent agents who have their own interests and, therefor...

Information Retrieval Systems normally deal with keywordbased technologies. Although those systems reach satisfactory results, they aren’t able to answer more complex queries done by users, especially those directly in...

In the information age, knowledge leads to profits, power and success. As an ancestor of data mining, machine learning has concerned itself with discovery of new knowledge on its own. This paper presents experiment resul...

Este trabalho apresenta uma metodologia visual, com utilização de um modelo fundamentado na teoria de sistemas multiagentes para a reorganização de um curso técnico em edificações. Apresenta-se uma nova convençã...

The notion of context and its importance in knowledge representation and nonmonotonic reasoning was first discussed in Artificial Intelligence by John McCarthy. Ever since, contexts have found many applications in devel...

In this work, we de fine some non-prioritized merge operators, that is, operators for the consistent union of belief bases. We de ne some postulates for several kinds of merge operator and we give different construction...

The objective of this paper is the construction of an Essential Object Model for Information Systems. This model is derived from the organization workflows representing the business processes and follows rules described ...

In [1] we presented the logic P=PML, a formalism suitable for the speci cation and construction of Real-Time systems. The main algebraic result, namely, the interpretability of P/PML into an equa- tional calculus based o...

The appropiate definition of argumentative reasoning systems requires a careful study of the dialectical analyses that are carried out in these formalisms. In thiswork we present a research line that points to the correc...

During a system’s life cycle, new requirements or changes in the existing ones imply modifying the system. Aspect-oriented software development is a new approach to the modularization of systems, yet it does not provid...

The term Animated Systems has been introduced in the bibliography in reference to interactive dynarnic worlds simulations, composed of interacting independent objects [Tra96]. Simulation is a powerful tool because it al...

In the last years software researchers have been looking for ways of assembling systems in a style of software construction similar to “LEGO blocks”. Software components are reusable building blocks for constructing ...

One of the greatest challenges in Heterogeneous Photocatalysis process for water treatment is to obtain immobilized photocatalyst with a high surface area and good photocatalytic activity, combined with suitable mechanic...

In this paper we show an innovative way to represent graphic designs 01 systems and to verify design properties. The graphic designs are thought as models of an extended modal logic; and the methods used to verify proper...

Frameworks são a implementação de uma estrutura de aplicação genérica e reusável, a qual pode ser especializada para aplicações específicas, através da criação de subclasses ou componentes reusáveis. Frame...

The increasing complexity of software systems makes their development complicated and error prone. A widely used and generally accepted technique in software engineering is the combination of different models (or views) ...

The structured techniques for systems analysis and design are still the most widely known. One of the alternatives of this technique is the JAD methodology (Joint Application Design). This methodology is an improvement w...

Nowadays information circulates quickly in a human organization, what generates an internal difficulty in preserving inside the organization essential information to support decision-making. Decision Support Systems (DSS...

La correcta estimación temprana de un proyecto de software es una tarea difícil o casi imposible. Sin embargo la mayor parte de los sistemas que son desarrollados por terceros requieren fijar un precio antes de contrat...

Os campi universitários são organizações complexas que se assemelham nos aspectos físicos a cidades e nos aspectos administrativos e organizacionais a empresas e, portanto, apresentam diversos problemas que devem se...
