The indoor localization of mobile users is currently a central issue for many applications and fields, including sensor networks, asset management, healthcare, ambient-assisted living, and public safety personnel localization. Existing solutions often rely on the fusion of information from multiple sensors. The potential of using an ultra wideband (UWB) system for wireless distance measurement based on the round-trip time (RTT) has been investigated in this thesis. Non-coherent UWB receivers have been analyzed using two different approaches: amplitude detection and energy detection. Both non-c

Abstract:
Time alignment is performed on a conventional PET scanner in order to reduce the noise in the image from undesirable interactions, called randoms. In time of flight scanners this alignment is even more critical in order to place the position of an annihilation accurately. Traditionally, the alignment is an iterative process done by adjusting time offsets and recording the count rate until it is maximized. We have designed and built a positron detector that can be placed in the PET scanner. This enables each crystal in the scanner to be aligned to the same event (the positron detection), pr

Abstract:
Ultrawideband (UWB) is one of the promising technologies for future short-range high data rate communications (e.g. for wireless personal area networks) and longer range low data rate communications (e.g. wireless sensor networks).Despite its various advantages and potentials (e.g. low-cost circuitry, unlicensed reuse of licensed spectrum, precision ranging capability etc.), UWB also has its own challenges. The goal of this dissertation is to identify and address some of those challenges, and provide a framework for practical UWB transceiver design.In this dissertation, various modulation opti

Abstract:
Cette thèse présente une étude de la sensibilité à la physique au delà du modèle standard et en particulier aux couplages anormaux entre les photons et les bosons W. Ceci est réalisé en détectant dans ATLAS les protons intacts après interaction et en mesurant leur temps de vol avec une précision de quelques pico-secondes de part et d'autre du détecteur central.Je décrirai également les photo-détecteurs de grande superficie avec une précision de quelques pico-secondes et les algorithmes de reconstruction de temps basés sur l'échantillonnage rapide du signal.

Abstract:
Accelerated protons are excellent candidates for treating several types of tumours. Such charged particles stop at a defined depth, where their ionisation density is maximum. As the dose deposit beyond this distal edge is very low, proton therapy minimises the damage to normal tissue compared to photon therapy. Nonetheless, inherent range uncertainties cast doubts on the irradiation of tumours close to organs at risk and lead to the application of conservative safety margins. This constrains significantly the potential benefits of proton over photon therapy and limits its ultimate aspirations.

Abstract:
Cette thèse étudie l’optique quantique multimode, aussi bien du point de vue de la génération que celui de la détection. Elle s’articule autour de trois volets. Nous étudions la génération de lumière comprimée multimode dans une cavité. Pour cela nous considérons la forme la plus générale de hamiltonien quadratique, permettant entre autres de décrire l’utilisation de plusieurs pompes dans un matériau effectuant du mélange à quatre ondes. Une approche combinant fonctions de Green et décompositions de matrices symplectiques est décrite. Cette théorie générique est appliquée à des cas particulier

Abstract:
Negli ultimi decenni, i miglioramenti tecnologici nei processi planari per la produzione di circuiti integrati CMOS hanno contribuito allo sviluppo di nuovi dispositivi allo stato solido ad elevate prestazioni, tra i quali vale la pena menzionare i fotomoltiplicatori al silicio. La peculiarità di questi sensori, meglio conosciuti con l’acronimo SiPM, riguarda l’amplificazione intrinseca che essi presentano quando vengono fatti funzionare in modalità Geiger; infatti, quando la tensione di polarizzazione è superiore alla tensione di breakdown del dispositivo, i SiPM sono in grado di generare un
