Analysis of caloric intake and its relationship with body composition in univer...
Parraca, J.A.; Marmeleira, J.; Bravo, J.; Raimundo, A.; Batalha, Nuno; Tomas-Carus, P.Thirty-one older people (age 70,2±6,3 years) were randomly assigned to an experimental group (n=16), performing 16 weeks, 2 weekly sessions of 30 min of exercise with warm up (5 min bycicle and 5 min 4 set of exercises) 30 sec x 4 sets of whole body vibration (WBV) with 60 sec of rest between sets; or to a control group (n=15). Maximal isokinetic strength was measured at 60º/s in the knee extensors and flexors ...
High Levels of Physical Activity May Promote a Reduction in Bone Mineral Densit...
Raimundo, A.; Charrua, Z.; Batalha, Nuno; Pereira, C.; Parraca, J. A.; Tomas-Carus, P.Background and objectives: Peritoneal dialysis (PD) patients are expected to present lower levels of physical activity, unhealthy changes at the body composition level, and low levels of strength. Firstly, this study aimed to report the sex differences in physical activity, body composition and muscle strength and the relations among these variables. Secondly, we analyze the relationship between physical activi...
YOLOX-Ray: An efficient attention-based single-staged object detector tailored ...
Raimundo, A.; Pavia, J. P.; Sebastião, P.; Postolache, O.Industrial inspection is crucial for maintaining quality and safety in industrial processes. Deep learning models have recently demonstrated promising results in such tasks. This paper proposes YOLOX-Ray, an efficient new deep learning architecture tailored for industrial inspection. YOLOX-Ray is based on the You Only Look Once (YOLO) object detection algorithms and integrates the SimAM attention mechanism for ...
AI-based smart sensing and AR for gait rehabilitation assessment
Monge, J.; Raimundo, A.; Ribeiro, G.; Postolache, O.; Santos, J.Health monitoring is crucial in hospitals and rehabilitation centers. Challenges can affect the reliability and accuracy of health data. Human error, patient compliance concerns, time, money, technology, and environmental factors might cause these issues. In order to improve patient care, healthcare providers must address these challenges. We propose a non-intrusive smart sensing system that uses a SensFloor sm...
The impact of the COVID-19 pandemic on airlines’ passenger satisfaction
Pereira, F.; Costa, J. M.; Ramos, R. F.; Raimundo, A.This study aims to understand airline passengers' satisfaction trends by analyzing the most influential factors on satisfaction before and during the COVID-19 pandemic. The sample consists of a dataset with 9745 passenger reviews published on airlinequality.com. The reviews were analyzed with a sentiment analysis tool calibrated for the aviation industry for accuracy. Machine learning algorithms were then imple...
Can two multimodal psychomotor exercise programs improve attention, affordance ...
Rosado, Hugo; Bravo, Jorge; Raimundo, A.; Carvalho, J.; AlmeidaG.; Pereira, C.Background Falls are associated with cognitive and physical function deterioration. Attention decline, inaccurate affordance perception, and balance impairment are considered to be risk factors for falls. Furthermore, few studies have reported psychomotor intervention as a fall prevention program. This study aimed to investigate the effects of two multimodal programs on attention, perceptual and stepping-forwar...

Impact of active and passive hypoxia as re-warm-up activities on rugby players´...
Ramos-Campo, D.J.; Malta, J.; Olcina, G.; Timón, R.; Raimundo, A.; Tomas-Carus, P.Abstract: The aim of this study was to analyse the effect of four types of re-warm-up (R-WU) activity, namely rest in normoxia (RN) at FiO2 = 20.9%, rest in hypoxia (RH) at FiO2 = 15%, activity (4 × 5 jumps/15 s) in normoxia (AN) and activity in hypoxia (AH) on physical performance. Ten elite male rugby players completed a 15-min warm-up followed by one of the 15-min randomized R-WU strategies. After R-WU, coun...
Neural architecture search for 1D CNNs - Different approaches tests and measure...
Cordeiro, J.; Raimundo, A.; Postolache, O.; Sebastião, P.In the field of sensors, in areas such as industrial, clinical, or environment, it is common to find one dimensional (1D) formatted data (e.g., electrocardiogram, temperature, power consumption). A very promising technique for modelling this information is the use of One Dimensional Convolutional Neural Networks (1D CNN), which introduces a new challenge, namely how to define the best architecture for a 1D CNN....
