Abstract:

El gran col· lisionador de hadrons (LHC), el qual te un circumferencia de 27 quilometres, és l'accelerador de partícules més gran i potent del món. El LHC esta dissenyat per fer col· lisionar protons a 14 TeV en el seu centre de massa, aconseguint una lluminositat de 1024 cm-2 s-1, quan 2808 paquets amb 1011 protons cada un, circulen per l'accelerador. Els paquets estan espaiats per 25 ns, que corresponen a una freqüencia de col · lisió de 40 MHz en cada un dels quatre punts d'interacció.

Abstract:

Electronic noses (e-noses) have been utilized during the past three decades as general purpose instruments for chemical sensing. These instruments are inspired by natural olfactory systems, where fine odour discrimination is performed without the necessity for highly specialized receptors. Instead, odour information is extracted in these systems using arrays of broadly tuned receptors organized in a convergent pathway. Such a sensing architecture allows combining the responses of the array of receptors, giving rise to particular representations of the different odour stimuli. The key advantage

However, in the case of unknown signal duration, the performance of this detector decreases. For this scenario, a detector system composed of multiple windows may be preferred. Window sizes of such a system will also be fixed beforehand but they will be different from each other. Therefore, one of the windows will better match the signal duration, giving better detection results. In this study, multiple window detectors are analyzed. Their false a

However, observing sources lower than a few Hz requires going into space where the interferometer arms can be longer and where there is no seismic noise.

Abstract:

L’Organització Europea per a la Investigació Nuclear (CERN) està implementant actualment una important actualització del Gran Col·lisionador d’Hadrons (LHC) de 27 quilòmetres, amb l’objectiu d’expandir l’abast de la física, augmentant la lluminositat i desencadenant la consegüent multiplicació d’interaccions per feix de partícules. Les noves condicions operatives de l’LHC d’alta lluminositat (HL-LHC) tindran un impacte directe en els sensors de traçat de silici dels detectors principals, els experiments ATLAS i CMS, causant un gran augment de l’ocupació dels sensors i danys per radiació.

Abstract:

La investigación presentada está centrada en la mejora de sensores de gas conductométricos de Sn02. Se analizan sensores en capa gruesa y en capa delgada. En el primer caso, el polvo de Sn02 necesario para fabricar los sensores ha sido elaborado mediante la técnica de sol-gel. Tras la obtención de un precursor (Sn02 hidratado), se han realizado estudios de calcinación, introducción de aditivos metálicos (Pt, Pd) y, por primera vez, un molido del material. Gracias a la disponibilidad de nanopartículas con tamaño de grano entre 3 y 100 nm, se ha podido analizar por primera vez el espectro Raman

Abstract:

Este trabalho propõe um método biotelemétrico para a determinação simultânea de duas características elétricas (moduláveis por parâmetros fisiológicos) de circuitos RLC passivos para microsensores injetáveis. Como o ambiente sob monitoração envolve a presença de íons (tecidos biológicos), a utilização de dipolos torna-se inviável, desta forma, o estabelecimento de um acoplamento indutivo entre o sensor e o dispositivo para o registro das medidas é necessário. Tratando-se de um dispositivo injetável, as dimensões da bobina do sensor são diminutas (diâmetro da ordem de mm), sugerindo cuidados es

Abstract:

The lack of passive, wireless, chemical and biological sensor systems is a significant impediment to sensor system applications. While active sensors with a wireless communications link continue to decrease in power consumption, they still require a power source, such as a battery. This active power consumption limits the useful life of the sensor and its applications. A more attractive solution would be a passive, wireless, chemical and biological sensor integrated with a wireless interrogation platform to monitor the sensor. The focus of this thesis is the realization of a wireless sensor in

Abstract:

Near infrared (NIR) light detection has drawn substantial attentions in a variety of applications. NIR detectors prepared by the solution processable organic semiconductors and organic-inorganic hybrid material systems have the advantages for achieving flexible, light weight and large area NIR detection devices. The aim of this research work is to study the modulation of the photo-generated charge carriers in perovskite and polymer systems for attaining high performing solution-processable NIR phototransistors (PTs) and photodiodes (PDs). In the first part, an organo-lead halide perovskite/pol
