Resumo: In this work, we address the problem of image segmentation, subject to high-level constraints expected for the objects of interest. More specifically, we define closeness constraints to be used in conjunction with geometric constraints of inclusion in the Hierarchical Layered Oriented Image Foresting Transform (HLOIFT) algorithm. The proposed method Leia mais…
Abstract: In an era characterized by extensive credit use and rapidly advancing technology, mitigating fraud in online transactions is more critical than ever. This paper presents a systematic literature review (SLR) on applying Machine Learning Methods in fraud detection in online shopping.In addition, a comparative analysis of a more comprehensive Leia mais…
Resumo: Soil-structure interaction parameters for subsea applications are not easily obtained by traditional laboratory experiments such as triaxial, oedometer and direct shear tests. A complete comprehension of topics such as displacements, reaction forces, bending moments and friction factors is commonly a result of investigations through geotechnical physical models. Although small-scale Leia mais…
Abstract: The increasing use of smartphones in our lives, both for leisure and critical services, expands the attack surface, contributing to threats faced by applications. The concept of Trusted Computing is a way to mitigate these threats and make applications less susceptible to real attacks. This research suggests a systematic Leia mais…
Abstract: The onset of the COVID-19 pandemic has accelerated the adoption of digital solutions and smart devices, fundamentally altering daily activities like online shopping, e-government services, and home automation. This transition, while beneficial, has introduced new cybersecurity challenges, particularly in the domestic environment where smart home technologies are prevalent. Previously, Leia mais…
Abstract: Cybersecurity faces a constant increase in the development of techniques, malwares and cyber threats that exploit various vulnerabilities to achieve their objectives, presenting the potential to cause social and financial impacts for individuals and organizations. The complexity and diversity of cyber attacks make it difficult to create efficient responses, Leia mais…
