Fatigue has been identified as a major injury risk factor in football due to the increasing number of muscle injuries occurring at the end of matches and during congested weeks of training. Fatigue is known for affecting kinetic (i.e. ground reaction forces – GRF), kinematic and spatio-temporal parameters during running/playing football. Consequent...
This work proposes an application of unsupervised deep learning (DL) on 2-D images containing VI diagrams of measured railway pantograph quantities to find patterns in operating conditions (OCs) and waveform distortion. Measurement data consist of pantograph voltage and current measurements from a Swiss 15 kV 16.7 Hz commercial locomotive and a Fre...
The current energy crisis has revealed deep vulnerabilities in energy supplies. It also emphasised the strong fossil fuel dependency of many countries. Some governments decided to tighten their energy policies, particularly on energy efficiency and the use of intermittent and renewable energies. Photovoltaic energy has the advantage of emitting few ...

To quantify and compare the external peak demands (PD) encountered according to game result (win vs. loss), quarter result (win vs. tie vs. loss), and quarter point difference (± difference in score) in under-18 years (U18), male basketball players. Thirteen basketball players had external load variables monitored across 9 games using local positio...
peer reviewed / In this work, a virtual load monitoring framework is proposed for deriving a mapping from either high or low frequency (1-Hz /10-minute time averaged) SCADA data to load signals, while preserving the high frequency dynamic components of the latter. Specifically, the proposed virtual load monitoring scheme relies on a data-driven mod...

Performing multiple high-intensity interval training (HIIT) sessions in a compressed period of time (approximately 7-14 days) is called a HIIT shock microcycle (SM) and promises a rapid increase in endurance performance. However, the efficacy of HIIT-SM, as well as knowledge about optimal training volumes during a SM in the endurance-trained popula...

This study aimed to analyse the influence of different contextual factors (i.e., defensive style and game outcome) on basketball players’ external load during games-based drills using ultrawideband (UWB) technology. Fourteen male professional basketball players belonging to an elite reserve Spanish club (ACB) participated in this study. The games-b...

An extension of the baseline non-intrusive load monitoring approach for energy disaggregation using temporal contextual information is presented in this paper. In detail, the proposed approach uses a two-stage disaggregation methodology with appliance-specific temporal contextual information in order to capture time-varying power consumption patter...
This thesis explores load monitoring on dc micro-grids specifically applied to Naval shipboard power systems. More electronic loads are being placed on Naval ships and, increasingly, more of these loads are pulsed-power in nature; drawing pulsating current from the grid. This presents a challenge for conventional fault monitoring devices as many fa...
