Relacion del perfil del cortisol salival en adolescentes de 14-15 anos de edad, con la depresion, ansiedad y reactividad emocional KU Leuven
This study examines the association between the hypothalamic-pituitary- adrenal axis deregulation and depression, anxiety, and emotional reactivity in nonpsychiatric 14-15-year-old adolescents (n=58). Samples of cortisol, well-known as the stress hormone, were collected from saliva at awakening, noon and evening. Individuals showing similar diurnal cortisol profiles were grouped using duster analysis. Repeated measurements were performed to ...
Boundaries of pre-emption rights in real estate transactions Vrije Universiteit Brussel
De wet- of decreetgever voorziet in diverse onroerende voorkooprechten. De mogelijkheid bestaat ook om conventionele voorkooprechten te vestigen. Die wettelijke, decretale of conventionele voorkooprechten worden niet altijd strikt nageleefd. Rechtsonderhorigen tasten de grenzen van het voorkooprecht af. Soms wordt het voorkooprecht bewust of onbewust miskend. De miskenning van het voorkooprecht moet worden onderscheiden van de verkeerdelijke ...
UWB-Ego-Motion Particle Filter for Indoor Pose Estimation of a Ground Robot Using a Moving Horizon Hypothesis Vrije Universiteit Brussel
Ultra-wideband (UWB) has gained increasing interest for providing real-time positioning to robots in GPS-denied environments. For a robot to act on this information, it also requires its heading. This is, however, not provided by UWB. To overcome this, either multiple tags are used to create a local reference frame connected to the robot or a single tag is combined with ego-motion estimation from odometry or Inertial Measurement Unit (IMU) ...
Phase-spatial beamforming for decoding motion-onset visual evoked potentials KU Leuven
My PhD aims at improving the functionality of brain-computer interfaces in comfort, communication speed and ease-of-use. All BCI I develop are based on electroencephalography communication and I focus mainly on the development of new artificial intelligence and signal processing techniques to improve the three prior points. My expertise lies in signal processing and transfer learning in BCI setting.
Embroidery triboelectric nanogenerator Ghent University
The “Embroidery Triboelectric Nanogenerator” (E-TENG) is a wearable device that extracts energy from human motion by making use of the triboelectric phenomena, in addition to conductive fabric along with embroidery threads. One of the greatest ways to transform ambient vibrational energy from the human body is to use a wearable triboelectric energy harvester. In this study, different E-TENGs were developed using conductive fabric as an electrode ...
Online tracking of dynamically time-varying inertia using an enhanced SDFT-based estimation methodology University of Antwerp
The overall motion performance of mechatronic machines depends heavily on proper knowledge of the machine’s characteristics, among which the inertia. Moreover, the inertia of most multi-body mechanisms, for example, reciprocating slider-crank mechanisms, varies as a function of the machine position, thereby challenging optimal control. Nevertheless, the inertia’s variation is sometimes not known accurately enough or changes over time due to, ...
Analytic Evaluation of Nonadiabatic Couplings within the Complex Absorbing Potential Equation-of-Motion Coupled-Cluster Method KU Leuven
We present the theory for the evaluation of nonadiabatic couplings (NACs) involving resonance states within the complex absorbing potential equation-of-motion coupled-cluster (CAP-EOM-CC) framework implemented within the singles and doubles approximation. Resonance states are embedded in the continuum and undergo rapid decay through autodetachment. In addition, nuclear motion can facilitate transitions between different resonances and between ...
Shear wave elastography using diverging wave imaging with sliding-window coherent compounding Ghent University
Shear wave elastography is a promising tool for non-invasive assessment of myocardial stiffness. As cardiac shear waves (SW) are very short-lived, their detection using ultrasound necessitates high frame rate imaging. More specifically, diverging wave imaging with coherent compounding is typically used, requiring a trade-off between time resolution and image quality. Hence, the aim of this study was to investigate if this trade-off can be ...
