Abstract:

A theoretical probability distribution function for neutron triplet correlation that is amenable to experimental determination of the reactivity of a neutron multiplying system has been obtained. A two-dimensional data collection method designed for the experiment was implemented with the aid of an interface counting board installed in a microcomputer system. An efficient non-linear least-squares code was developed to fit experimental data to the theoretical distribution function to obtain reactivity. The system developed for data collection and analysis is fully portable, requiring only a mic

The differences between a musical score and an instance of that music in a performance, communicates a performer’s view of the information contained in that score. The main hypothesis in this thesis is that by measuring quantiﬁable parameters such as tempo, dynamics and motion from live performance, the performer’s interpretation of musical structure can be detected. This will be tested for pieces for which the structure is explicit and obvious, and then used to discover musical structure from looking at patterns of aural and visual performance parameters in performances of more ambiguously st

This thesis describes a study into the development of an optimum material and fabrication process for the production of thick film pH electrodes. These devices consist of low cost, miniature and rugged pH sensors formed by screen printing a metal oxide bearing paste onto a high temperature (-850 °C) fired metal back contact supported on a standard alumina substrate. The pH sensitive metal oxide layer must be fabricated at relatively low temperatures (<300 °C) in order to maintain the pH sensitivity of the layer and hence requires the use of a suitably stable low temperature curing binder.

Abstract:

Nuclear magnetic resonance (NMR) is a powerful experimental technique for probing the local environment of nuclei in materials. However, it can be difficult to separate the large number of interactions that are recorded in the resulting spectra. First-principles calculations based on quantum mechanics therefore provide much-needed support for interpreting experimental spectra. In this way, the underlying mechanisms recorded in experimental spectra can be investigated on an atomic level, and trends can be noted with which to guide the direction of future experiments.

The result is a mathematical model that relates the sources to the measurements.

Abstract This thesis presents computational studies of both the static and dynamic parameters of the nuclear magnetic resonance (NMR) spectroscopy of gaseous xenon. First, state-of-the-art static magnetic resonance parameters are computed in small xenon clusters by using methods of quantum chemistry, and second, time-dependent relaxation phenomena are investigated via molecular dynamics simulations at different experimental conditions. Based on the underlying quantum and classical mechanics concepts, computational methods represent a procedure complementary to experiments for investigating the

Abstract:

Le travail de cette thèse porte sur le développement de modèles neutroniques innovants pour le couplage avec la thermohydraulique, associant précision et temps de calcul raisonnable. Un des cas d'application principaux étant le réacteur à sel fondu, à spectre neutronique rapide et en cycle thorium MSFR (Molten Salt Fast Reactor), réacteur de 4ème génération à combustible liquide circulant, la prise en compte du mouvement des précurseurs de neutrons retardés et des phénomènes associés est nécessaire. Les études de conception de ce type de réacteur ont été le point de départ de ces développement

Abstract:

L’objectif de cette thèse est l'étude par spectroscopie laser colinéaire à haute résolution de la structure nucléaire des isotopes d’étain riches en neutrons, vers de la fermeture de couche N=82 et au-delà. Les structures hyperfines et les déplacements isotopiques le long de ¹⁰⁸⁻¹³⁴Sn ont été mesurés en utilisant l’expérience COLLAPS à ISOLDE au CERN. Deux expériences indépendantes, utilisant des propriétés de transitions complémentaires l’une à 452 et l’autre à 286 nanomètres, ont étudiées les états 5p6s ¹P₁ et 5p6s ³P₁ dans l'atome neutre. L'état singlet fournit une sensibilité élevée au mom

Abstract:

A proposta deste trabalho é estudar as distribuições de prótons e nêutrons e suas deformações na região da \"ilha de inversão\". Esta região, situada entre 10 Z 14 e 19 N 21, apresentar anomalias como núcleos fortemente deformados perto do número mágico N=20. Os parâmetros de deformação de carga e de matéria dos isótopos de 24Mg, 30Mg e 32Mg foram medidos, via espalhamento inelástico do feixe secundário de Mg, através de um experimento realizado no Laboratório GANIL, Caen, França. Um feixe primário de 36S, a 77 MeV/núcleon, produziu, via fragmentação do projétil sobre um alvo de 12C, feix
