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.

Although during stress mode, both PMOS and NMOS devices are stressed, the proposed structure isolates the PBTI and NBTI degradation during test mode. A methodology of converting any data-path into ring oscillator (DPRO) is also presented.

Hydrogen is mainly produced from the steam reforming of natural gas and water gas shift reactions. The major products of these processes are hydrogen and carbon dioxide. 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. In underactuated mechanical systems (UMSs) its application requires the satisfaction of matching conditions, which in many cases demands to solve partial differential equations (PDEs). 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

We present a characterization of Kcv properties at the single-channel level. In symmetric 100 mM K+, single-channel conductance is 114 ± 11 pS.

Bifenilos policlorados (PCBs) e pesticidas organoclorados são compostos que não ocorrem naturalmente no ambiente e não são facilmente degradados química ou microbiologicamente. Seu estudo no ambiente é importante devido à sua persistência, toxicidade, lipossolubilidade e conseqüente biomagnificação. Por isso, representam a maioria dos poluentes orgânicos persistentes (POPs) considerados prioritários pela UNEP (United Nations Environmental Programme) e banidos ou restritos pela Convenção de Estocolmo, de maio de 2001. Tais poluentes podem ser facilmente emitidos para a atmosfera, atingindo área

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

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

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
