Miniaturized liquid metal composite circuits with energy harvesting coils for b...

Over the past years, rapid progress has been made on soft-matter electronics for wearable and implantable devices, for bioelectronics and optogenetics. Liquid Metal (LM) based electronics were especially popular, due to their long-term durability, when subject to repetitive strain cycles. However, one major limitation has been the need for tethering bioelectronics circuits to external power, or the use of rigid...

Portuguese sociology: a unique form of internationalisation

Towards Mobile Federated Learning with Unreliable Participants and Selective Ag...

Recent advances in artificial intelligence algorithms are leveraging massive amounts of data to optimize, refine, and improve existing solutions in critical areas such as healthcare, autonomous vehicles, robotics, social media, or human resources. The significant increase in the quantity of data generated each year makes it urgent to ensure the protection of sensitive information. Federated learning allows mach...

Sensing and Artificial Perception for Robots in Precision Forestry: A Survey

Artificial perception for robots operating in outdoor natural environments, including forest scenarios, has been the object of a substantial amount of research for decades. Regardless, this has proven to be one of the most difficult research areas in robotics and has yet to be robustly solved. This happens namely due to difficulties in dealing with environmental conditions (trees and relief, weather conditions,...

Potencialidades do software na procura de consensos no ensino superior em conte...

Contexto e Objetivo: De que modo o software se pode constituir como instrumento da facilitação metodológica perante restrições à pesquisa de campo durante uma pandemia? Porque é importante buscar consensos em momentos de exacerbação e de radicalização de opiniões e de comportamentos? Estas duas questões foram o ponto de partida para argumentarmos que o software potencia e acelera a investigação em contextos de ...

Software capabilities in the search for consensus in higher education in a pand...

Background and Aim: How can software become an instrument of methodological facilitation in the face of restrictions to field research such as those brought about by the pandemic? Why is it important to seek consensus in times of exacerbation and radicalization of opinions and behaviors? These two questions were the starting point for arguing that software powers and accelerates research in contexts of confinem...

Ecos Coloniais: Histórias, Patrimónios e Memórias

Integrada na XXIV Semana Cultural da UC, a exposição dedicada à cidade de Lisboa, mas sinalizando outras cidades e locais em Portugal, resulta de um exercício coletivo e dialógico de investigação sobre o seu património histórico e cultural, interrogado a partir das suas múltiplas intersecções com a história colonial e imperial portuguesa. Exercício crítico – certamente provisório, a carecer de aprofundamento e ...

The dilemma of international students at UC in a pandemic context

The internationalization of Portuguese universities is a priority for the Portuguese national government and for Portuguese higher education institutions. Nevertheless, the attraction of foreign students has brought additional challenges to universities, to the extent that, subject to an increase in internal diversity and heterogeneity, they face difficulties in integrating IS. Sporadically, there are students ...

Corruption and Inflation in Agricultural Production: The Problem of the Chicken...

Corruption and inflation are two economic problems with serious social consequences. This paper analyzes the link between these two problems, focusing on the case of 19 prices observed for agricultural products in 90 countries since 2000. Using ‘panel data cointegration’ techniques, we conclude that, in most cases, there is a long-term relationship between inflation and corruption. The direction of causality fa...
