Abstract:
L’utilisation de drones est fréquente dans de nombreuses industries et dans les activités militaires modernes. Toutefois les drones militaires à longue endurance souffrent encore d’un taux élevé d’accidents liés à des erreurs humaines, en particulier lorsque les opérateurs ressentent de la fatigue mentale (FM).En particulier, la flexibilité cognitive exigée des opérateurs offre une possibilité d’amélioration. Cependant, peu de recherches ont été menées sur celle-ci lors de tâches complexes tel que le contrôle d’un drone.Dans cette thèse, nous remédions à cette lacune, et la possibilité d’attén

Nanoparticles represent promising carriers for controlled drug delivery.

It was found that the Nanosight and Gas Chromatography are valuable instrumentsfor detecting and analysing degradation, whereas the Zetasizer turned out to giveunreliable results because of increasing polydispersity in the samples.

The selective removal of CO2 from the product gas is important because it poisons catalysts in the reactor and it is highly corrosive. Membrane separation processes for hydrogen purific

Alternative energy sources are needed if the current use of energy is to be sustained while reducing global warming. A possible alternative energy source that has significant potential is hydrogen. For hydrogen to become a serious contender for replacing fossil fuels, the production thereof has to be further investigated. One such process, the membrane–based Hybrid Sulphur (HyS) process, where hydrogen is produced from the electrolysis of SO2, has received considerable interest recently.

Interconnection and damping assignment passivity-based control (IDA-PBC) is a wellknown technique which regulates the behavior of nonlinear systems, assigning a target port-Hamiltonian (pH) structure to the closed-loop.

Only recently, the IDA-PBC has been extended to UMSs modeled implicitly, where the system dynamics in pH representation are described by a set of differential-algebraic equations (DAEs). In some

La presente tesis pretende demostrar que un programa de entrenamiento basado en prácticas breves de mindfulness, respiración coherente y compasión (como prácticas principales) y así como también, acceder a un estado “mindful” de consciencia a través de “prácticas informales” en la vida cotidiana, produce cambios significativos en la disminución de síntomas de ansiedad, depresión estrés y burnout y en el aumento de las capacidades de mindfulness, descentramiento y autocompasión, así como también produce un incremento de la HRV en los participantes. Para demostrar esto, se presenta el diseño del

Abstract:
In the models analyzed in this paper, there exists an incumbent politician with one objective, two choices, and voters who remember the past differently. The politician's primary goal is to get reelected, which is done by maximizing the number of votes on the day of election. The politician can increase their chances of reelection if they influence the state of the economy over time and ensure the economy is in its 'best' state on the days leading up to the election. In conducting this research, I wanted to study how different rates of memory decay influences the choices the politician makes d

La batterie hybride PbC est constituée d'une électrode faradique dont la matière active est le dioxyde de plomb et d'une électrode capacitive de carbone activé identique à celle utilisée dans les supercondensateurs. L'association de composants d'un accumulateur classique au plomb et d'un supercondensateur permet d'obtenir des performances intermédiaires entre un supercondensateur et un accumulateur. Le supercondensateur possède une puissance spécifique très élévée et une durée de vie de plusieurs millions de cycles tandis que la batterie peut être assimilée à un réservoir énergétique ayant un

This article focuses on the different ways in which the concepts of teaching and learning are conceived. It also defines the conception on which the educational view of the PBL is based, and how it determines its learning goals. Likewise, it shows how evaluation strategies are bonded to each of the stages in the PBL process, noting their features and the relation with learning goals of the methodology.<br>El artículo discute las diferentes concepciones acerca de la enseñanza y el aprendizaje, caracterizando aquellas que constituyen el fundamento de la visión educativa del ABP y que condicionan

Les modules d’électronique de puissance sont appelés à être fortement intégrés et poussés aux limites de leurs capacités de fonctionnement. D’autre part, ces modules sont souvent soumis à des environnements thermiques sévères qui peuvent altérer profondément les propriétés des semi-conducteurs, voire même les détruire. La température peut jouer un rôle essentiel dans les mécanismes de dégradation. Ce travail a pour objectif la prise en compte des mécanismes de dégradation dans les composants microélectroniques, de type VDMOS de puissance, sur leurs performances électriques. Une analyse numériq

In questo scenario quanto mai complesso e articolato, si inserisce il presente lavoro di Tesi avente come obiettivo il design di nuovi materiali biobased e biodegradabili da utilizzare nell’imballaggio alimentare primario e dunque caratterizzati da bu

Der Prozess der DNA-Kondensation stellt in allen lebenden Organismen einen komplizierten Prozess dar. Der Größenunterschied zwischen DNA-Molekül und Zelle bzw.

Im Laufe der Evolution haben sich unterschiedliche Prozesse entwickelt, um diese Aufgabe erfolgreich durchzuführen. So kodieren z.B. eukaryotische Zellen für Proteine, so genannte Histone, die wie in einer Spule von der DNA eng umschlungen werden. Dadurch ist es möglich die DNA zu kondensieren und e
