BINLI: An Ontology-Based Natural Language Interface for Multidimensional Data A...

Current technology facilitates access to the vast amount of information that is produced every day. Both individuals and companies are active consumers of data from the Web and other sources, and these data guide decision making. Due to the huge volume of data to be processed in a business context, managers rely on decision support systems to facilitate data analysis. OLAP tools are Business Intelligence soluti...

Using Constraints for Intrusion Detection: The NeMODe System

In this work we present NeMODe a declarative system for Computer Network Intrusion detection which provides a declarative Do- main Specific Language for describing computer network intrusion signa- tures that could spread across several network packets, which allows to state constraints over network packets, describing relations between sev- eral packets, and providing several back-end detection mechanisms whic...

Time means… species! On the performance of species richness estimators and diff...

Species richness is accounted as the oldest and the simplest concept of species diversity, being widely used in scientific grounds for monitoring and assessment purposes. However, the challenge is to correctly estimate the number of species. Not only estimates should be accurate, but also should be precise for correct assessment of a system’s state and trend. This study aims to determine differences between est...

Predictive Adaptive Control of water level in canal pools

A case study on the use of a predictive adaptive algorithm to control pool level in a pilot water distribuition canal is described. The algorithm is a modification of the basic MUSMAR controller that includes parallel integral action and, in the case of multiple pools, feedforward action to coordinate the gates. Experimental results in the case of a single pool and simulations for multiple pools are presented. ...

Adaptive Predictive Controller Applied to an Open Water Canal

This paper concerns to the application of adaptive control to a large scale water canal experimental plant. Water canals are complex spatially distributed systems which aim at distributing water either for irrigating, or domestic, or industrial purposes. In this paper a predictive adaptive control algorithm (MUSMAR) is applied to a large scale experimental water canal prototype. The experimental facilities wit...

Electron Ionization Mass Spectrometric Study of Some Substituted 1,3-oxazoles

Comunicação oral sob a forma painel ; Heterocyclic compounds are widely used as pharmaceuticals. Tacrine (THA) was the first drug approved for the treatment of Alzheimer’s disease (AD) and a great effort has been made to design and synthesize new THA-analogues in order to evaluate their beneficial effects as therapeutic agents in this disease.1-6 Contrasting with the pharmaceutical interest, mass spectrometric...

A classificação do desempenho escolar: Um estudo exploratório e contextualizado

Dissertação de Mestrado em Psicologia Educacional ; No sentido de esclarecer como é que os estagiários lidam com a prática da classificação do desempenho escolar efectuámos um estudo exploratório com o objectivo de procurar perceber quais os critérios em que se baseiam estagiários do 2o ciclo ao classificarem uma prova de composição de língua portuguesa e de perceber se haverá alguma diferença entre o início e...
