Unified Data Governance in Heterogeneous Database Environments: An API-Driven A...
Abbasi, Maryam; ANTUNES VAZ, PAULO JOAQUIM; Silva, José; Cardoso, Filipe; Sá, Filipe; Martins, PedroModern organizations increasingly rely on heterogeneous database environments that combine relational, document-oriented, and key-value storage systems to optimize performance for diverse application requirements. However, this technological diversity creates significant challenges for implementing consistent data governance policies, regulatory compliance, and access control across disparate systems. Tradition...
Performance Comparison of Python-Based Complex Event Processing Engines for IoT...
Abbasi, Maryam; Cardoso, Filipe; ANTUNES VAZ, PAULO JOAQUIM; Silva, José; Sá, Filipe; Martins, PedroThe proliferation of Internet of Things (IoT) devices has intensified the need for efficient real-time anomaly and intrusion detection, making the selection of an appropriate Complex Event Processing (CEP) engine a critical architectural decision for security-aware data pipelines. Python-based CEP frameworks offer compelling advantages through the seamless integration with data science and machine learning ecos...
Stories in a shoe box - Entangled narratives of Nature
Silva, José; Marques, Tiago; Silva, EmaThe present climate challenges require the development of different tactics and some outside the realm of pure rationalisation, strategies that focus on emotional and romantic relationships with the space of Nature. The investigation follows a descriptive case methodology. The narratives developed by Hans Christian Andersen were the starting point for the project developed in Learning Settings at the University...
Mapping beyond the horizon
Silva, José; Marques, Tiago; Silva, EmaThe design of interfaces has an extensive focus, which goes beyond the screen design. The objective of this study, developed in learning settings at the University of Évora, Course of Interface Design, first curricular semester of 22/23, was to explore two perspectives of Interface Design. The project focused on mapping six sites related to Nature Spots beyond the horizon established from the classroom. The pro...
CHARTING NEW DIRECTIONS IN A TRANSFORMATIVE ERA
Silva, José; Marques, TiagoTypography, the art and technique of arranging type to make written language clear, readable, and visually appealing, is being reimagined for an era of screens, dynamic layouts, and interactive interfaces. This shi does not mean abandoning tradition; it is an evolution that encourages new exploration. As the papers in this book show, compelling research today o en connects our field’s historical foundations wit...
Reasoning Connections in Project Development - The Contribution of Prompt Desig...
Silva, José; Marques, TiagoThis study investigates the influence of AI-generated prompts on re- flexivity in visual exploratory mapping for project solution identification and refinement within design education. Modern design necessitates a strong user focus to achieve successful innovation, addressing the complexity of diverse user groups and shifting market needs. The research proposes a novel physical visual mapping methodology that e...
A Practical Performance Benchmark of Post-Quantum Cryptography Across Heterogen...
Abbasi, Maryam; Cardoso, Filipe; Vaz, Paulo; Silva, José; Martins, PedroThe emergence of large-scale quantum computing presents an imminent threat to contemporary public-key cryptosystems, with quantum algorithms such as Shor’s algorithm capable of efficiently breaking RSA and elliptic curve cryptography (ECC). This vulnerability has catalyzed accelerated standardization efforts for post-quantum cryptography (PQC) by the U.S. National Institute of Standards and Technology (NIST) an...
Head-to-Head Evaluation of FDM and SLA in Additive Manufacturing: Performance, ...
Abbasi, Maryam; ANTUNES VAZ, PAULO JOAQUIM; Martins, Pedro; Silva, JoséThis paper conducts a comprehensive experimental comparison of two widely used additive manufacturing (AM) processes, Fused Deposition Modeling (FDM) and Stereolithography (SLA), under standardized conditions using the same test geometries and protocols. FDM parts were printed with both Polylactic Acid (PLA) and Acryloni trile Butadiene Styrene (ABS) filaments, while SLA used a general-purpose photopolymer resi...
Performance and Scalability of Data Cleaning and Preprocessing Tools: A Benchma...
Martins, Pedro; Cardoso, Filipe; Vaz, Paulo; Silva, José; Abbasi, MaryamData cleaning remains one of the most time-consuming and critical steps in modern data science, directly influencing the reliability and accuracy of downstream analytics. In this paper, we present a comprehensive evaluation of five widely used data cleaning tools—OpenRefine, Dedupe, Great Expectations, TidyData (PyJanitor), and a baseline Pandas pipeline—applied to large-scale, messy datasets spanning three dom...
LAR@MSL Team description paper 2025
Ribeiro, António Fernando Alcântara; Lopes, Carolina; Ribeiro, Cláudio; Martins, Rui; Oliveira, TIago; Borges, Daniel; Araújo, Jorge; Silva, JoséThe LAR@MSL team has participated in MSL for years, from 1999-2007, 2011, 2016, and again in 2023 and 2024. This Team Description Paper aims to briefly explain the robots’ structure, hardware, and software and highlight the most significant changes introduced this year. It is important to note that new students have joined the team and are adapting to the league. This year’s updates include implementing a new M...
