- Um algoritmo para dimensionamento de ciclonesPublication . Maurício, Pedro; Silva, Pedro; Fonseca, Ana; Duarte, PedroOs ciclones são instrumentos de separação gás-sólido, largamente utilizados na indústria. O seu dimensionamento resulta da conjugação de diversas variáveis que afectam a performance deste equipamento, muitas vezes através de um processo iterativo baseado na experiência do executante, com alguma subjectividade associada. Neste estudo desenvolveu-se um algoritmo de dimensionamento automático de ciclones que permite obter resultados fiáveis, optimizando as dimensões e o número de ciclones e respectivas dimensões a partir de duas restrições – eficiência mínima de captura das partículas e perda de carga máxima do gás. Cyclones are gas-solid separation devices, largely used in industry. The cyclone design process is based on the combination of several variables that influence its performance. This is an iterative process dependent, most of the times, on individual experience. In this study, an algorithm was developed for automatic cyclone designing, which has produced reproducible results, optimizing the dimensions and the number of cyclones given two limiting conditions – minimum particle capture efficiency and maximum head loss.
- The impact of digital in learning spaces: an analysis on the perspective of teachers in higher educationPublication . Silva, Pedro; Gouveia, Luis BorgesThe generalized use of Communication Networks and Information Technologies is nowadays a global phenomenon. It has multiple impacts on how to teach/learn and on the contexts in which this process takes place (the Learning Environments). These areas include Physical Learning places, Virtual Learning sites, Collaborative Learning Spaces, among others. These proposals provide new scenarios for the teaching/learning process, but their outlines are not well defined yet. A Learning Space requires a complex set of materials and human resources. Further and continued research is significant and justified by the relevance of Higher Education Institutions.The overall objective of the present research is to understand the perceptions of the Professors in their Learning Environments. In this context it has been considered relevant to gather opinions on the needs/priorities, utility, quality and sustainability, as a result of the use of Information and Communication Technologies (ICT) in the teaching/learning spaces.
