Este documento reflecte o trabalho realizado durante o ano lectivo de 2008/2009, pelo aluno Ricardo Guedes, na área de mestrado em Design de som, do curso de Som e Imagem da Universidade Católica Portuguesa. O projecto envolve a sonorização completa de uma curta-metragem, realizada pelos alunos de mestrado em Televisão, ou seja, desde a fase de pré-produção e experiências, até à captação sonora no local das filmagens, foleys, ADR, efeitos sonoros, edição e mistura de som e banda sonora. O filme pertence ao género thriller, apenas com duas personagens, existindo muita tensão, suspense e terror. Apesar de não ter sido este o argumento proposto inicialmente, este é na verdade, um bom “exercício” para a elaboração do som e da música. Deste modo, no presente documento, é explicada toda a concepção, desenvolvimento e criação do pro...

Institutions have been creating their own specific weblab infrastructures. Usually, they use distinct software and hardware architectures comprehending instruments and modules (I&M) able to be parameterized but difficult to be shared. These aspects are impairing their widespread in education, since collaboration between institutions, in developing and sharing resources, is still low. To handle both aspects, this paper proposes the adoption of the IEEE1451.0 Std. with FPGA technology for creating reconfigurable weblab infrastructures. It is suggested the adoption of an IEEE1451.0 infrastructure with compatible instruments, described in Hardware Description Languages (HDL), to be reconfigured in FPGA-based boards. Besides an overview of the IEEE1451.0 Std., this paper presents a solution currently under development which se...

IMRT is a state-of-the-art cancer treatment method that delivers high doses of radiation directly to cancer cells in a very targeted way, much more precisely than is possible with conventional radiotherapy. IMRT can deliver higher radiation doses directly to cancer cells while sparing more of the surrounding healthy tissue. This has important advantages in head and neck cancers as it allows the beams to hit their target area while missing the surrounding structures, minimizing acute and late side effects.The purpose of this article is to describe the IMRT technique, its clinical applications and advantages, when comparing to the conventional Radiotherapy.
