Using petri nets for analysis of navigation paths in constrained graphs – appli...
Gomes, Luis; Ribeiro-Gomes, José; Barros, João PauloIn many areas of application, graphs have been used to support path planning addressing navigation challenges in dynamic environments. Applications target very diverse areas, ranging from manufacturing and robotics to video games, including georeferencing applications in our daily lives considering real-time traffic conditions. This paper focuses on applications where navigation through a predefined map consist...
Science CHANGing Policy Conference
Filipe, Susana; Branquinho, Cristina; Alegria, Carla; Oliveira, Rubén; Couto, Nazaré; Pedroso, Nuno; Eufrázio, Sofia; Gomes, LuisThe world faces a series of different global changes, which are complex in nature and require urgent action from Academia, Public and Private Organizations and Governments. The Institute for Global Change and Sustainability, Associated Laboratory CHANGE, integrates researchers from multidisciplinary areas of expertise that shall enable the development of appropriate solutions targeting the present and future en...
DEVICE AND PROCESS FOR MASSIVE CAPTURE OF OLIVE FLIES - ELECTROCUTOR TRAP
Rei, Fernando; Gomes, Luis; Andrade, Leonardo; Tlemcani, Mouhaydine; Peça, José; Dias, AntónioThe present invention relates to the develop- ment of a device for capturing flying insects, in particular the olive fruit fly (Bactrocera oleae), for biological control of this olive grove pest. [0002] This device is autonomous and active in oper- ation and comprises a substantially cylindrically shaped outer body, as well as a fan and an insect-trapping mech- anism both placed inside such outer body, whereby ...
Depression and Anxiety of Portuguese University Students: A Cross-Sectional Stu...
Amaro, Pedro; Fonseca, César; Afonso, Anabela; Jacinto, Gonçalo; Gomes, Luis; Pereira, Helder; José, Helena; Silva, Celso; Lima, Andreia; Arco, HelenaABSTRACT: The mental health of university students has worsened over time, and it is young people who have suffered the most from the COVID-19 pandemic in terms of mental health. Anxiety and depression are the most common symptoms reported by university students and are often the cause of disabilities, either in academic performance or in other spheres of life. Aim. The aim of this study was to both assess the ...
Functional evolution in total knee arthroplasty: first and second-generation pa...
Fontes, Ana Paula; CINTRA, RUI; Gomes, Luis; João Paulo SousaBackground: This study compares the functional evolution between the first- and second-generation patient-specific instrumentation and conventional instrumentation pre-surgery and the third month post-surgery after TKA. We analyzed the functional outcomes achieved and the absolute gains of each study variable. In addition, we aimed to elucidate the results of the three surgical techniques regarding the surgery ...
A Contextual Reinforcement Learning Approach for Electricity Consumption Foreca...
Ramos, Daniel; Faria, Pedro; Gomes, Luis; Vale, ZitaThe energy management of buildings plays a vital role in the energy sector. With that in mind, and targeting an accurate forecast of electricity consumption, in the present paper is aimed to provide decision on the best prediction algorithm for each context. It may also increase energy usage related with renewables. In this way, the identification of different contexts is an advantage that may improve predictio...
Smart Grid Ecosystem Modeling Using a Novel Framework for Heterogenous Agent Co...
Pereira, Helder; Ribeiro, Bruno; Gomes, Luis; Vale, ZitaThe modeling of smart grids using multi-agent systems is a common approach due to the ability to model complex and distributed systems using an agent-based solution. However, the use of a multi-agent system framework can limit the integration of new operation and management models, especially artificial intelligence algorithms. Therefore, this paper presents a study of available open-source multi-agent systems ...
Impact of Forecasting Models Errors in a Peer-to-Peer Energy Sharing Market
Gomes, Luis; Morais, Hugo; Goncalves, Calvin; Gomes, Eduardo; Pereira, Lucas; Vale, ZitaThe use of energy sharing models in smart grids has been widely addressed in the literature. However, feasible technical solutions that can deploy these models into reality, as well as the correct use of energy forecasts are not properly addressed. This paper proposes a simple, yet viable and feasible, solution to deploy energy management systems on the end-user-side in order to enable not only energy forecasti...
Assessment of Energy Customer Perception, Willingness, and Acceptance to Partic...
Gomes, Luis; Coelho, António; Vale, ZitaThe adoption of smart grids is becoming a common reality worldwide. This new reality is starting to impact energy customers as they face a dynamic grid in which they can actively participate. However, if energy customers are not prepared to participate actively, they can have their energy costs increased. This paper provides a review of acceptance models and customer surveys around the world made to assess the ...
