Stability of autonomous power systems with reversible hydro power plants: A stu...

This paper addresses the dynamic stability analysis of an islanded power system regarding the installation of a reversible hydro power plant for increasing renewable energy integration. Being a high-head facility, the hydro power plant consists of separated pumps and turbines (Pelton type). In order to properly support the identification of hydro pumps connection requirements and the technology to be used, diff...

ESEIG Mobile: An M-Learning Approach in a Superior School

Grey wolf optimization for PID controller design with prescribed robustness mar...

The grey wolf optimization algorithm is proposed to design proportional, integrative and derivative controllers using a two degrees of freedom control configuration. The control system is designed in order to achieve good set-point tracking and disturbance rejection performance. The design is accomplished by minimizing an aggregated cost function based on the time-weighted absolute error integral, subjected to ...

Identification and Characterization of Inter-Organizational Information Flows i...

Objectives: To understand and build a collective vision of all existing institutions in the Portuguese National Health Service as well as to perceive how and how far the interaction between those multiple institutions is supported by Information Systems (IS). Methods: Upon identification of the institutions involved in the healthcare process, a set of interviews with experienced people from those institutions w...

A novel and simple approach to define artisanal fisheries in Europe

Although the importance of the social, economic, environmental and traditional importance of artisanal fisheries is widely accepted, there is no single internationally accepted definition for this activity, since its characteristics differ among countries. Notwithstanding, it is also generally accepted that artisanal fisheries comprises a group of characteristics that clearly differ from those of the industrial...

Predicting malignancy from mammography findings and image-guided core biopsies

The main goal of this work is to produce machine learning models that predict the outcome of a mammography from a reduced set of annotated mammography findings. In the study we used a dataset consisting of 348 consecutive breast masses that underwent image guided core biopsy performed between October 2005 and December 2007 on 328 female subjects. We applied various algorithms with parameter variation to learn f...

The MINDS Method: Integrating Management and Interaction Design Perspectives fo...

As technology innovation rapidly changes service experiences, service designers need to leverage technology and orchestrate complex service systems to create innovative services while enabling seamless customer experiences. Service design builds upon contributions from multiple fields, including management, information technology, and interaction design. Still, more integration to leverage the role of technolog...

Hubs for VirtuosoNext: Online verification of real-time coordinators

Cross-modal domain adaptation for text-based regularization of image semantics ...

In query-by-semantic-example image retrieval, images are ranked by similarity of semantic descriptors. These descriptors are obtained by classifying each image with respect to a pre-defined vocabulary of semantic concepts. In this work, we consider the problem of improving the accuracy of semantic descriptors through cross-modal regularization, based on auxiliary text. A cross-modal regularizer, composed of thr...
