Esta pesquisa propõe uma reflexão a respeito dos processos de recepção de produtos culturais por parte do telespectador infantil. A problematização está em investigar, valendo-se dos referenciais teóricos das mediações comunicativas da cultura e do enfoque integral da audiência, como as crianças com idade entre 7 e 12 anos interagem com as narrativas audiovisuais, especialmente com a série de animação televisiva, para desta perspectiva compreender como se dão a apropriação e a produção de sentidos no cotidiano, tomando-se por base a interpretação do desenho animado Doug Funnie. O estudo emprega como metodologia a revisão de literatura combinada ao grupo de discussão norteado pelo modelo teórico-metodológico da mediação múltipla formulado por Guillermo Orozco Gómez, com base no paradigma das mediações de Jesús Martín-Barbero. A pesquisa de recepção, realizada em ambiente escolar, constatou que a comunicação midiática é de natureza dialógica e implica em reconhecimento e projeção do interlocutor no universo da ficção, assim, a produção de sentidos em relação ao desenho animado não está contida no audiovisual, mas no contexto sociocultural no qual interlocutores relacionam-se entre si e com os meios. E desta interação emergem a compreensão e a recriação dos produtos culturais, sinalizando que as interpretações do telespectador infantil revelam a sua maneira de ver o mundo.

Des recherches au Québec (Garon, 2009), en France (Donnat, 2011) et aux États-Unis (Kolb, 2001) confirment un état de fait général: le vieillissement du public de la musique classique. Si le public du répertoire est reconnu pour posséder un haut niveau d’études, pourquoi les étudiants universitaires de nos jours ne sont-ils pas plus présents dans les salles de concert ? Cette étude explore cette problématique d’abord par une recherche historique et par des entrevues auprès de certains des organismes de musique classique à Montréal, et ce afin de comprendre leurs stratégies de développement des publics concernés de 2004 à 2014. Ensuite, par un sondage auprès de 555 étudiants universitaires de la ville, pour faire un portrait de leur relation avec la musique à l’heure actuelle. Notre analyse, appuyée par une bibliographie en sociomusicologie et en sociologie des pratiques culturelles, confirme des tendances comme celle de l’«omnivorisme culturel» et l’éclectisme musical des jeunes universitaires. Elle nous montre aussi une réception positive des œuvres classiques, quoiqu’incompatible avec les critères esthétiques des genres musicaux favoris. À partir de ce paradoxe, nous étudions la force des motivations extramusicales qui les amènent aux concerts, leurs formats préférés, l’impact de l’éducation musicale, l’influence des parents, de l’internet, des nouvelles technologies. Finalement, nous constatons le nombre peu élevé d’initiatives des organismes musicaux dans le milieu universitaire à Montréal qui, pourtant, se montre un bassin au grand potentiel pour le renouvellement des publics de la musique classique.

Magnetic field inhomogeneity results in image artifacts including signal loss, image blurring and distortions, leading to decreased diagnostic accuracy. Conventional multi-coil (MC) shimming method employs both RF coils and shimming coils, whose mutual interference induces a tradeoff between RF signal-to-noise (SNR) ratio and shimming performance. To address this issue, RF coils were integrated with direct-current (DC) shim coils to shim field inhomogeneity while concurrently emitting and receiving RF signal without being blocked by the shim coils. The currents applied to the new coils, termed iPRES (integrated parallel reception, excitation and shimming), were optimized in the numerical simulation to improve the shimming performance. The objectives of this work is to offer a guideline for designing the optimal iPRES coil arrays to shim the abdomen.

In this thesis work, the main field () inhomogeneity was evaluated by root mean square error (RMSE). To investigate the shimming abilities of iPRES coil arrays, a set of the human abdomen MRI data was collected for the numerical simulations. Thereafter, different simplified iPRES(N) coil arrays were numerically modeled, including a 1-channel iPRES coil and 8-channel iPRES coil arrays. For 8-channel iPRES coil arrays, each RF coil was split into smaller DC loops in the x, y and z direction to provide extra shimming freedom. Additionally, the number of DC loops in a RF coil was increased from 1 to 5 to find the optimal divisions in z direction. Furthermore, switches were numerically implemented into iPRES coils to reduce the number of power supplies while still providing similar shimming performance with equivalent iPRES coil arrays.

The optimizations demonstrate that the shimming ability of an iPRES coil array increases with number of DC loops per RF coil. Furthermore, the z direction divisions tend to be more effective in reducing field inhomogeneity than the x and y divisions. Moreover, the shimming performance of an iPRES coil array gradually reach to a saturation level when the number of DC loops per RF coil is large enough. Finally, when switches were numerically implemented in the iPRES(4) coil array, the number of power supplies can be reduced from 32 to 8 while keeping the shimming performance similar to iPRES(3) and better than iPRES(1). This thesis work offers a guidance for the designs of iPRES coil arrays.
