Revisão epidemiológica da toxoplasmose no nordeste transmontano: perspetiva one health
Publication . Pereira, Tifany; Quintas, Helder; Lopes, Ana Patrícia; Caldeira, Maria João; Salvador, Sílvia; Rodrigues, Carina; Latitude
A toxoplasmose é uma zoonose causada pelo protozoário Toxoplasma gondii, com impacto na saúde humana, animal e ambiental. Representando um excelente exemplo do conceito “One Health”. A infeção ocorre principalmente pela ingestão dos diferentes estádios infetantes do parasita: oocistos esporulados eliminados por felídeos e presentes no ambiente (água, solo e alimentos contaminados), cistos teciduais em carne crua ou mal cozinhada, e taquizoítos, por via transplacentária durante a gestação. A toxoplasmose é geralmente assintomática em humanos e animais saudáveis, mas pode causar complicações graves em imunodeprimidos e gestantes. Os pequenos ruminantes são os animais de produção mais suscetíveis, e a doença está associada a perdas reprodutivas e representa um risco zoonótico pelo consumo de carne infetada.
User-Centered Dashboard Design in Serious VR Game for Cognitive Rehabilitation
Publication . Neto, Jecé Xavier; Lopes, Júlio Castro; Naves, Thiago França; Lopes, Rui Pedro
The product designer plays a crucial role in creating products that captivate and fulfill users’ needs in an exceptional way. Based on this, this work aimed to demonstrate how a user-centered product designer can play a crucial role in solving the pains of the target audience. With this in mind, this paper proposes the design of a dashboard for a clinical team to visualize a rehabilitation session, focusing the product on the user experience. Several Deep Learning (DL) algorithms are expected to be used to extract biometric data from the patients, in order to feed a Dynamic Difficulty Adjustment (DDA) module, based on Reinforcement Learning (RL). The method proposed in this study is based on the study of the customer experience. To this end, a roadmap was drawn up with the stages of developing a data visualization platform. Afterward, user satisfaction was assessed using the System Usability Scale (SUS), resulting in a usability score of 81.6 points. It can be concluded that analyzing the data from this study reinforces the ongoing importance of User-Centred Product Design in creating effective and successful digital products.
Microservices architecture to enable an open platform for realizing zero defects in cyber-physical manufacturing
Publication . Lopes, Rui Pedro; Ibrahim, Ahmed; Barbosa, José; Leitão, Paulo
The market's demand for high-quality products necessitates innovative manufacturing approaches that emphasize flexibility, adaptability, and the reduction of defects. Traditional systems are currently evolving towards embracing I4.0 technologies, including data collection, processing, analytics and digital twin, aiming for zero-defect manufacturing quality. This paper introduces an open platform, compliant with RAMI4.0 standards, designed to improve manufacturing quality. The platform integrates data using Asset Administration Shells with microservices adaptation for data ingestion and advanced analytics. Additionally, it incorporates Non-Destructive Inspection tools, demonstrating a seamless integration of measurement and quality assurance. This study details the architectural specification and validation of the openZDM platform, employing microservices to ensure flexibility, modularity and scalability, aligning with the RAMI4.0 model. The platform was validated through deployment in an automotive assembly line, highlighting its effectiveness in integrating inspection scenarios and early defect detection tools. The architecture employs a choreographed approach to manage loosely coupled microservices, enabling efficient data lifecycle management from collection through analytics to visualization.
Modeling and control of an educational manipulator robot joint
Publication . Coelho, J. A. B.; Brancalião, Laiany Suganuma; Alvarez, Mariano José; Costa, Paulo; Gonçalves, José
Integrating physical robots in an educational context often entails acquiring Expensive equipment that often operates using proprietary software. Both conditions restrict the students from exploring and fully understanding the internal operation of robots. In response to these limitations, a three-degree-of-freedom robotic manipulator, based on the “EEZYbotARM MK2” open-source design by Carlo Franciscone, is being repurposed and integrated within the SimTwo simulation environment to operate within a hardware-in-the-loop architecture. To accomplish this objective, first, an open-source Arduino-based library was developed aiming at the robot’s online and offline programming akin to industrial robots. The firmware is able to communicate with the SimTwo software in which the digital twin’s robot is living. The dynamic behavior of the robot’s digital twin must be properly parametrized and aligned with the physical robot’s dynamics. This article describes the modeling of the robot joint’s actuator and its closed-loop controller formulation. The obtained results show that the dynamic behavior of the robot joint digital twin closely matches both open and closed-loop, the one of its physical counterpart.
Enhancing video projector connectivity and management with a low-cost solution
Publication . Paulo, Fabio Fraga; Oliveira, Pedro Filipe; Matos, Paulo
The video projector serves as an essential device for various purposes, such as education, corporate functions, and conferences. This article presents an affordable setup aimed at upgrading video projection equipment, including older models, with enhanced management and sharing features. The proposed solution tackles frequent connectivity challenges arising from differences in connectors, transmission methods, and mismatches in configurations (like frequency and resolution) between computers and projectors. Such incompatibilities often result in delays and hinder the effective use of video projectors. By incorporating a Raspberry Pi and three dedicated applications, this system introduces an intuitive solution that supports innovative teaching and work methods.
