This thesis discusses certain issues related to the treatment of classification problems using techniques that rely on Boolean concepts. The interest of using Boolean-based models in classification is demonstrated with the help of LAD (Logical Analysis of ...
Geographical Information Science and Cultural Anthropology are aimed to collaborate on development projects dedicated to indigenous communities. This fact is first based on a growing intention to integrate the reality and the perception of the development ...
The purpose of this paper is to provide an overview of our approach for modeling enterprise web applications (EWA), which is use case driven and uses UML as the modeling language. Our approach delivers a conceptual, logical model of the application, which ...
Rankine cycles for low to medium power and low temperature heat using water as working fluid, were almost written off. The main arguments speaking against them are reviewed in this paper and the conceptual design of the equipment entirely revisited. An adv ...
In the past, the problem of semantic interoperability in information systems was mostly solved by means of centralization, both at a system and at a logical level. This approach has been successful to a certain extent, but offers limited scalability and fl ...
This thesis proposes to address the well-know database integration problem with a new method that combines functionality from database conceptual modeling techniques with functionality from logic-based reasoners. We elaborate on a hybrid - modeling+validat ...
This thesis explores the use of specifications for the construction of correct programs. We go beyond their standard use as run-time assertions, and present algorithms, techniques and implementations for the tasks of 1) program verification, 2) declarative ...
Information systems, including their core databases need to meet changing user requirements and adhere to evolving business strategies. Traditional database evolution techniques focus on reacting to change to smoothly perform schema evolution operations an ...
A setup to monitor the daylighting performance of different glazing types in Singapore is presented. The glazing is installed in the facade of four dedicated testing chambers in BCAA's Zero Energy Building in Singapore. These test rooms are equipped with s ...
This paper addresses the problem of building scalable semantic overlay networks. Our approach follows the principle of data independence by separating a logical layer, the semantic overlay for managing and mapping data and metadata schemas, from a physical ...
