Fair shares or smart savings? exploring business models, justice and efficiency...
Scharnigg, Renée; Monteiro, Jânio; Pacheco, André; Santos, JoniEnergy communities are increasingly playing an important role in citizen engagement during energy transitions. However, the functional benefits for participants are heavily reliant on how energy and profits are shared, which are dictated by regulations. While optimizing trade-offs can prove significant in making energy community projects viable, related techno-regulatory innovations on energy-sharing mechanisms...
Comparative viability of photovoltaic investments across european countries usi...
Carvalho, Jailson Pereira de; Lopes, Eduardo B.; Santos, Joni; Monteiro, Jânio; Cabrita, Cristiano Lourenço; Pacheco, AndréElectrical grids are undergoing a transformation driven by the increasing integration of renewable energy sources on the consumer side. This shift, alongside the electrification of consumption—particularly in areas such as electric mobility—has the potential to significantly reduce CO2 emissions. However, it is also contributing to a rise in electricity prices due to growing demand and infrastructure costs. Par...
Enhancing efficiency in solar non-intrusive desalination: solar still prototype...
Pacheco, André; Sequeira, Claudia; Silva, Manuela Fernanda Gomes Moreira da; Serrão Sousa, VâniaAccess to freshwater is a pressing global challenge. Despite being irreplaceable freshwater is an increasingly scarce resource, especially in regions as Southern Europe, due to high human pressure and climate change. Solar desalination presents a low impact solution to produce freshwater from seawater, particularly in sun-rich regions. The main goal of this study was to develop a modular solar desalination syst...
Um modelo de metadados para a autenticidade das descrições arquivísticas digitais
Pacheco, André; Silva, Carlos Guardado da; Freitas, Maria Cristina Vieira deO advento do paradigma informacional abalou muitos dos princípios da teoria e da prática arquivística. Um dos tópicos mais prementes prende-se com perceber até que ponto a informação digital pode ser confiável. Os recursos digitais são representados por metadados, e a confiança baseia-se na demonstração da sua autenticidade. Uma vez que os elementos tradicionais de verificação da autenticidade de documentos ana...
Development and implementation of a smart charging system for electric vehicles...
Santos, Joni; Francisco, André; Cabrita, Cristiano Lourenço; Monteiro, Jânio; Pacheco, André; Cardoso, PedroThere is currently exponential growth in the electric vehicle market, which will require an increase in the electrical grid capacity to meet the associated charging demand. If, on the one hand, the introduction of energy generation from renewable energy sources can be used to meet that requirement, the intermittent nature of some of these sources will challenge the mandatory real-time equilibrium between genera...
A metadata model for authenticity in digital archival descriptions
Pacheco, André; Da Silva, Carlos Guardado; De Freitas, Maria Cristina VieiraThe advent of the information paradigm has shaken many of the principles of archi- val theory and practice. One key issue is knowing to which extent can digital infor- mation be trusted. Digital resources are represented by metadata, and trust consists in demonstrating their authenticity. Since the traditional elements used to verify the authenticity of analog records are not suitable in the digital world, the ...
Application of simple harmonic motion theory to the prediction of floating wind...
Mackie, G.; Pacheco, André; Sequeira, C.An alternative solution for achieving a high stability floating foundation for supporting large horizontal axis wind turbines is compared against current floating offshore wind solutions. The testing of a 1:36th scale model of the solution, called Starfloat, in the wind/wave basin of the Cantabria Coastal and Ocean Basin, Santander and the design of this physical model, including scaling issues, is discussed. A...
Flood vulnerability under sea level rise for a coastal community located in a b...
Croteau, Raphaelle; Pacheco, André; Ferreira, ÓscarSea level rise will be a major threat to coastal communities within the next century due to the intensity and severity of the floods it can cause. A new methodology considering water infiltration, slope, and hydraulic connectivity was developed to assess the potential inundation extension associated with different total water level and sea level rise scenarios on sandy coasts. This methodology was applied for t...
Aplicação dos princípios do Novo Serviço Público ao processo disciplinar a part...
Pacheco, AndréDissertação (mestrado profissional) - Universidade Federal de Santa Catarina, Centro de Ciências Jurídicas, Programa de Pós-Graduação em Direito, Florianópolis, 2021.; A aplicação do direito disciplinar é uma preocupação constante dos órgãos públicos de todas as esferas da Administração Pública. A abordagem dominante sobre o tema é fundada na aplicação da legislação pertinente, que se ocupa apenas dos aspectos ...
Energy transition process and community engagement on geographic islands: the c...
Pacheco, André; Monteiro, Jânio; Santos, Joni; Sequeira, Claudia; Nunes, J.Islands have the potential to be precursors in the transition to clean energy, by adopting new technologies and applying innovative solutions that can serve as showcases at an international level. This paper is a contribution towards understating the importance of community engagement on energy transition processes. It covers multiple aspects of a green transition process, including technical, environmental, so...
