Parvathaneni, Keerthi Krishna. « Characterization and multiscale modeling of textile reinforced composite materials considering manufacturing defects ». Electronic Thesis or Diss., Ecole nationale supérieure Mines-Télécom Lille Douai, 2020. http://www.theses.fr/2020MTLD0016.
The influence of void-type manufacturing defects on the mechanical properties of textile composites was investigated both by experimental characterization and by multiscale modeling. In particular, voids characteristics such as not only void volume fraction but also its size, shape, and distribution have been characterized for textile composites and their effect on the mechanical properties have been analyzed. Several textile composite plates were fabricated by the resin transfer molding (RTM) process where 3D interlock glass textile reinforcement was impregnated by epoxy resin under a constant injection pressure to generate different types of voids. A series of mechanical tests were performed to examine the dependency of tensile modulus and strength of composites on the total void volume fraction, intra & inter-yarn void volume fraction, and their geometrical characteristics. Microscopy observations were performed to obtain the local information about fibers (diameter and distribution), and intra-yarn voids (radius, aspect ratio and distribution). Based on these results, a novel algorithm was proposed to generate the statistically equivalent representative volume element (RVE) containing voids. Moreover, the effect of void morphology, diameter and spatial distribution (homogeneous, random and clustering) on the homogenized properties of the yarns was also investigated by the finite element method. X-ray micro-computed tomography was employed to extract the real meso-scale geometry and inter-yarn voids. Subsequently, this data was utilized to create a numerical model at meso-scale RVE and used to predict the elastic properties of composites containing voids. A parametric study using a multiscale numerical method was proposed to investigate the effect of each void characteristic, i.e. volume fraction, size, shape, distribution, and location on the elastic properties of composites. Thus, the proposed multiscale method allows establishing a correlation between the void defects at different scales and the mechanical properties of textile composites
Feron, Maryse. « Étude des mécanismes neurophysiologiques de l'instabilité posturale dans la sclérose latérale amyotrophique à partir d'un modèle biomécanique de l'initiation de la marche ». Thesis, Paris 10, 2016. http://www.theses.fr/2016PA100187/document.
Postural instability is frequently reported in Amyotrophic Lateral Sclerosis (SLA) patients. However, the neural mechanisms that contribute to postural instability in SLA patients remain largely unknown. In comparison to both SLA patients without postural instability and controls, SLA patients with postural instability presented an altered anticipatory postural adjustment (APA) phase with a decreased posterior displacement of the center of foot pressure (CP) and a increased APA duration, decreased length and velocity of the first step and deficit of the dynamic postural control with a dramatic decreased braking index. Conversely, the gait initiation was not significantly modified in SLA patients without postural instability in comparison to controls. The reduced posterior CP displacement during the APA was significantly related to reduced grey matter volume of the left PCC, left SPL, right PPN and caudate nucleus, and the increased APA duration to the reduced grey matter volume of the left AMS and right cerebellum. The reduced velocity of the first step was significantly related to a decreased grey matter volume within the left PMC, right PPN and cerebellar vermis and the reduced braking index to decreased grey matter volume of the right CUN. These results suggest that postural instability of SLA patients result, at least partly, from dysfunction of brain regions and networks known to be involved in gait initiation and balance controls in human
Heide, Dr Bernd. « A Method For Modifying Segmented Human Voxel Models ». Universitätsbibliothek Chemnitz, 2002. http://nbn-resolving.de/urn:nbn:de:bsz:ch1-200200823.
Es wird eine praktische Methode zum Verändern von segmentierten menschlichen Voxel-Modellen dargelegt. Die Methode kann in der Medizinphysik im Zusammenhang mit Strahlendosisberechnungen angewendet werden. Sie kann jedoch auch in anderen Gebieten benutzt werden, bei denen menschliche Voxel-Modelle zur Anwendung kommen. Die grundlegende Strategie der Methode besteht aus den folgenden Schritten: 1. Erzeugung triangulierter Oberflächen aus Objekten (Organen, Knochen, Geweben) eines segmentierten menschlichen Voxel-Modells. 2. Durchführung interaktiver Oberflächendeformationen und/oder Verschiebungen. 3. Re-Überführung der triangulierten Oberflächen in Voxel-Darstellungen der Organe und Rückschreibung in das segmentierte menschliche Voxel-Modell. Das Voxel-Volumen der modifizierten Organe kann mindestens bis auf ein halbes Voxel genau eingestellt werden. Die Anwendbarkeit der Methode wird anhand der Milz einer Leukämie-Patientin demonstriert

As imagens radiográficas quando digitalizadas podem ser agrupadas em arquivos para gerar um modelo antropomórfico de elementos de volume, chamados fantomas tal como o MAX (Male Adult voXel) e o FAX (Female Adult voXel). Estes fantomas acoplados a um código Monte Carlo, que simula o transporte de radiação na matéria como o EGS4 (Elétron Gama Shower-versão 4), e um algoritmo de uma fonte radioativa constituem um Modelo Computacional de Exposição (MCE). Este modelo além de possuir o código e a fonte radioativa, possui sub-pastas com os fantomas MAX/FAX e um código do usuário (USERCODE). Nas pastas dos fantomas MAX/FAX encontram-se arquivos importantes para execução do MCE, tais como: mspectra.dat, o pegs4.dat,o max/fax.data,o max/fax.bone.data e o expo.input que contém dados operacionais do usuário e construído com a utilização do software FANTOMAS. Na pasta USERCODE foi declarada no arquivo max/fax.code.mor uma matriz, específica para este trabalho, chamada de RADDIGITAL que é preenchida pela transferência, feita pelo software DIP (Digital Image Processing), de valores de energia (em keV) dos arquivos EnergiaPorVoxel.dat oriundos da execução do MCE. A compilação de toda massa de dados (código EGS4, fantomas MAX/FAX com seus arquivos e os arquivos da pasta USERCODE gerou os arquivos Max.for e Fax.for que recompilados e vinculados geraram os arquivos Max.exe e Fax.exe que executam os MCE. A execução dos MCE geraram arquivos externos com informações de energia depositada nos voxels. Com estes arquivos, com o fantoma segmentado e utilizando o software DIP pode-se construir fantomas de saída com base em energia depositada por voxel e com base em valores de dose efetiva. Para se obter nos fantomas baseados na dose efetiva foi criado internamente no software DIP um vetor contendo os fatores de ponderação tecidual à radiação, aqui chamados de wDIP, calculado neste trabalho com base nos dados de radiosenssibilidade da ICRP 60. Desta forma, foram obtidos os fantomas contendo informações das frações de dose efetiva dos órgãos e tecidos radiosenssíveis. Assim foi possível ajustar, por exemplo, a energia máxima para 255 no fantoma de saída, chamados de fantomas sintéticos, para se ter uma distribuição de energia resultando numa distribuição de tons de cinza similar à observada nas radiografias convencionais e nas imagens de 8 bits. Os fantomas sintéticos são uma pilha cujas vistas radiográficas sagitais, coronais e transversais, em qualquer profundidade, foram chamadas de radiografias digitais sintéticas, onde utilizou-se técnicas de realce de imagens digitais no domínio espacial com a utilização do software DIP. A utilidade clínica destes fantomas pode diminuir os erros relacionados com a excessiva repetição de exames radiográficos convencionais e reduzir assim a dose recebida pelos pacientes
