The frequency behavior of the tunnel injection quantum dot vertical cavitysurface emitting laser (TIQD-VCSEL) is investigated by using an analyticalnumericalmethod on the modulation transfer function. The function is based on therate equations and is decomposed into components related to different energy levelsinside the quantum dot and injection well. In this way, the effect of the tunnelingpr...

A number of environmental modelling frameworks have been developed recently, and plans for new frameworks are under way. Examples such as TIME, OpenMI, SME and OMS share an approach to environmental modelling based on model components, and offer improved model development and deployment. These approaches have methods for ensuring model component-linking compatibility using manual and machine pr...

An approach to build a multi-class classifier is proposed in this paper. This approach consists of a derivation to show under which loss function an optimal classifier can be obtained. It also consists of a method of selection of principal components for multi-class classification through univariate logistic regressions. And it consists of a derivation of certain derivatives to rank the feature...

Educational multi-media applications can be deconstructed so that individual components, eg. video clips, sound clips, photographs and text can be reused in new multi-media applications. EuropeMMM (Efficient Usage of Remote and Online Publication of Electronic multi-media Materials) is an EU funded project addressing the custom publishing of multi-media components. A catalogue of multi-media co...

this paper presents theoretical and numerical state-of-the-art information in the field of hygro-thermo-mechanical deformation simulation in structural concrete. the aspects discussed include coupled hygro-thermo-mechanical performance of porous materials including concrete, multi-scale simulation of concrete properties especially the volumetric and structural deformation performance, and the m...

This paper presents an overview of the spoken and multimodal dialog Portuguese corpora collected in the context of the FASiL (Flexible and Adaptive Spoken Language and Multi-Modal Interfaces) project. The project developed a Virtual Personal Assistant application in the Personal Information Management domain, exploiting the state-of-theart of speech and multi-modal technology. The FASiL corpora...

We develop a novel probabilistic ensemble framework for multi-label classification that is based on the mixtures-of-experts architecture. In this framework, we combine multi-label classification models in the classifier chains family that decompose the class posterior distribution P(Y1, …, Yd |X) using a product of posterior distributions over components of the output space. Our approach captur...
