Questionable research practices in engineering research
Baptista, Ana Alice; Pereira, FilipeMisconduct in science is often associated with data fabrication, data falsification, and plagiarism. However, other practices are far more frequent and prevalent. Questionable Research Practices (QRPs) are in the grey area between misconduct and responsible research conduct. The goal of this study was to investigate estimated and self-admission prevalence of engineering researchers' engagement in QRPs. We appli...
Design of a yarn analysis mechatronic prototype for textile industry
Pereira, Filipe; Machado, José; Soares, Filomena; Vasconcelos, Rosa; Carvalho, VítorPortuguese textile industry faces challenges in a globalized market, needing enhanced competitiveness and superior product quality. The quality of textile products heavily relies on yarn excellence, demanding precise evaluation against predefined parameters. Despite advancements, existing yarn evaluation devices struggle with limitations like high costs, bulkiness and imprecise assessments. To overcome these ch...
Modelling and simulation of a Pick&Place system using modelica modelling langua...
Monteiro, Alberto; Pereira, Filipe; Santos, Adriano A.; Machado, José; Oliveira, MiguelModelica is a powerful modelling language for modelling and simulation of Multiphysics Engineering Systems behaviour. This work explores a model to be implemented in the control design of a 6-axis industrial manipulator whose structure approaches the robotic arm ABB IRB 140, through inverse kinematics calculation. The significance of an inverse kinematics model is to bring accuracy to the reference inputs into ...
Hydroagriculture project - A Portuguese case study
Silva, Paulo; Felgueiras, Carlos; Almeida Santos, Adriano Manuel; Pereira, FilipeWater plays an essential role in the social fabric and comfort of society, as it plays an important role in our survival and subsistence, in its accessibility, in economic activities, and in the particular case of this study, in the manufacture of agricultural products and activities. In a developing society, and with the number of the human population increasing, consumerism takes place, resulting in an increa...
An Energy Storage System for the Alto Douro Wind Power Plant: A Technical Study
Magalhães, Alexandre; Xavier, Celso; Felgueiras, Carlos; Pereira, Filipe; Almeida Santos, Adriano Manuel; da Silva, A. Ferreira; Silva, PauloRenewable energies are crucial to meeting global demand for environmentally friendly energy at a time when fossil fuels are being cut back. In recent years, and essentially due to the reduced reserves of fossil fuels, Portugal has been promoting investment in renewable energies as a way of freeing itself from energy imports and dependence on fossil fuels. However, despite the high number of hours of sunshine pe...
Integration of Artificial Vision and Image Processing into a Pick and Place Col...
Santos, Adriano A.; Schreurs, Cas; Silva, António Ferreira da; Pereira, Filipe; Felgueiras, Carlos; Lopes, António M.; Machado, Josén the field of robotics, pick and place applications are becoming increasingly popular due to their ability to automate repetitive tasks that can create temporary or permanent injuries. To enhance the efficiency of these applications, object recognition using a fixed camera or one mounted on a robotic hand has been employed. This paper explores the possibilities of implementing a low-cost camera into a collabor...
Vision inspection design for systematic production of needle beds: an industria...
Freitas, Luis; Malheiro, M. Teresa; Gonçalves, A. Manuela; Vicente, José; Pereira, Filipe; Morais, Francisco; Bessa, João; Machado, JoséThe increasingly standards of the electronic industry, especially in Printed Circuit Boards, make In-Circuit-Test Machines one of the most important systems on the production lines. With this, the pressure on the In-Circuit-Test Machines production to meet this strict requirements it is getting bigger every day. To react to this pressure it is necessary to update, in a technological point of view, the manufactu...
Hyperthermic Intrathoracic Chemotherapy. A new weapon has been deployed in Port...
Barata, Catarina; Ferreira, Ricardo; Draiblate, Beatriz; Pereira, Filipe; Brysch, Eva; Nobre, ÂngeloThymoma is a relatively rare tumour, being, nonetheless, the most frequent neoplasm of the anterior mediastinum. Radical surgery is the gold-standard in every stage, with a considerable recurrence rate in locally advanced tumours. Complete resection in recurrences occurs only in a few cases. A new therapeutic strategy has emerged: the Hyperthermic Intrathoracic Chemotherapy (HITHOC), a high concentrated dose of...
Online yarn hairiness– Loop & protruding fibers dataset
Pereira, Filipe; Pinto, Leandro; Soares, Filomena; Vasconcelos, Rosa; Machado, José; Carvalho, VítorThis paper introduces an online dataset focused on detect- ing hairiness in yarn, including loop and protruding fibers. The dataset is designed for use in assessing artificial intelli- gence algorithms. The dataset consists of 684 original images. Through augmentation, this number increases to 1644, with 11,037 annotations derived from videos featuring 56.4tex pur- ple cotton yarn. The videos were captured duri...
Energy Policies, Education and Sustainable Development Goals Applied to Low Dev...
Martins, Florinda; Silva, Paulo; Felgueiras, Carlos; Almeida Santos, Adriano Manuel; Pereira, Filipe; Caetano, NídiaEnergy, its use and management, weighs heavily on the burden that each society can impose on a fragile balance of nature, with implications not only environmental and financial, but also social, creating jobs and improving quality of life. Devising strategies that combine these three factors are a valuable option that will yield good results, meeting the challenge of fulfilling the Sustainable Development Goals...
