Water repellents in Rammed Earth Heritage Conservation: Using ancient products ...
Oliveira, Daniel; Ribeiro, TelmaEarthen heritage represents an important legacy regarding not only the history of construction but also the knowledge of a millenary practice based on empirical expertise, social conditions, and cultural development. Looking at nature and exploring all the local products that it could provide and how to use them to improve ways of living and building was a common strategy. And while earthen construction require...

BUSted!!! Microarchitectural side-channel attacks on the MCU bus interconnect
Rodrigues, Cristiano; Oliveira, Daniel; Pinto, SandroSpectre and Meltdown have pushed the research community toward an otherwise-unavailable understanding of the security implications of processors’ microarchitecture. Notwithstanding, research efforts have concentrated on highend processors (e.g., Intel, AMD, Arm Cortex-A), and very little has been done for microcontrollers (MCU) that power billions of small embedded and IoT devices. In this paper, we present BUS...
O electroencefalograma no doente com AVC
Oliveira, DanielO Eletroencafalograma (EEG) consiste numa técnica neurofisiológica com elevada sensibilidade na avaliação da função cerebral em tempo real, sendo considerado o exame gold standard para a identificação de atividade epileptiforme e crises epilépticas [1]. O Acidente Vascular Cerebral (AVC) é das causas mais comuns da ocorrência de crises epilépticas e epilepsia na fase adulta, sendo a incidência de epilepsia pós-...
IRQ coloring and the subtle art of mitigating interrupt-generated interference
Costa, Diogo; Cuomo, Luca; Oliveira, Daniel; Savino, Ida Maria; Morelli, Bruno; Martins, José; Biasci, Alessandro; Pinto, SandroIntegrating workloads with differing criticality levels presents a formidable challenge in achieving the stringent spatial and temporal isolation requirements imposed by safetycritical standards such as ISO26262. The shift towards highperformance multicore platforms has been posing increasing issues to the so-called mixed-criticality systems (MCS) due to the reciprocal interference created by consolidated subsy...
Contribution to the Understanding of the Colour Change in Bluish-Grey Limestones
Silva, Teresa; Oliveira, Daniel; Veiga, João Pedro; Lisboa, Vitor; Carvalho, Jorge; Barreiros, M. Alexandra; Coutinho, Mathilda; Salas-Colera, EduardoBluish-grey limestones have been extensively used as ornamental stones for decoration purposes in buildings, as well as in works of art, and accordingly, have been the target of intense exploration. In Portugal, the Jurassic limestone massif known as the Maciço Calcário Estremenho (MCE), has been the source of grey-coloured ornamental stones, namely the Azul Valverde (one of the most well-known bluish-grey lime...
IRQ coloring: mitigating interrupt-generated interference on ARM multicore plat...
Costa, Diogo; Cuomo, Luca; Oliveira, Daniel; Savino, Ida Maria; Morelli, Bruno; Martins, José; Tronci, Fabrizio; Biasci, Alessandro; Pinto, SandroMixed-criticality systems, which consolidate workloads with different criticalities, must comply with stringent spatial and temporal isolation requirements imposed by safety-critical standards (e.g., ISO26262). This, per se, has proven to be a challenge with the advent of multicore platforms due to the inner interference created by multiple subsystems while disputing access to shared resources. With this work, ...
Como garantir o controlo interno através de sistemas de informação: uma abordag...
Miguel, Sílvia; Gonçalo Marques, Célio; Oliveira, DanielO controlo interno é um processo de grande importância para as organizações. Consiste num conjunto de políticas e procedimentos e é desenvolvido para garantir a fiabilidade e a segurança a todas as partes interessadas. Neste sentido, torna-se crucial que as organizações tenham sistemas informáticos que auxiliem os gestores nas suas tomadas de decisão, garantindo que a informação apresentada é confiável. Assim, ...
Preventive conservation of vernacular adobe heritage located in seismic-prone r...
Sadeghi, Neda H.; Oliveira, Daniel; Azizi-Bondarabadi, Hamed; Correia, MarianaIn general, relevant actions to retrofit heritage should be considered before the occurrence of earthquakes. This proactive approach is preferred, rather than a reactive approach in an emergency situation, following the earthquake. These preventive actions are known as disaster mitigation, risk mitigation, disaster risk management, seismic upgrading and preventive conservation. In the case of vernacular heritag...
A perspective review on integrating VR/AR with haptics into STEM education for ...
Sanfilippo, Filippo; Blazauskas, Tomas; Salvietti, Gionata; Ramos, Isabel; Vert, Silviu; Radianti, Jaziar; Majchrzak, Tim A.; Oliveira, DanielAs a result of several governments closing educational facilities in reaction to the COVID-19 pandemic in 2020, almost 80% of the world’s students were not in school for several weeks. Schools and universities are thus increasing their efforts to leverage educational resources and provide possibilities for remote learning. A variety of educational programs, platforms, and technologies are now accessible to supp...
