Being happy, healthy and whole watching movies that affect our emotions

This paper discusses the power of emotions in our health, happiness and wholeness, and the emotional impact of movies. It presents iFelt, an interactive video application to classify, access, explore and visualize movies based on their emotional properties and impact.

A Representação de Personagens Virtuais: Como a Tecnologia Obriga à Criação de Estilos e Estéticas Interdisciplinares na Animação Contemporânea

The evolution of computer animation represents one of the most relevant andrevolutionary aspects in the rise of contemporary digital visual culture (Darlew,2000), in particular, phenomena such as cinema “spectacular “ (Ibidem) and videogames. This article analyzes the characteristics of this “culture of simulation” (Turkle, 1995:20) relating the multidisciplinary and spectrum of technical and stylistic choices to the dimension of virtual characters acting. The result of these hybrid mixtures and computerized human motion capture techniques - called virtual cinema, universal capture, motion capture, etc. - cosists mainly on the sophistication of “rotoscoping”, as a new interpretation and appropriation of the captured image. This human motion capture technology, used largely by cinema and digital games, is one of the reasons why the authenticity of the animation is sometimes questioned. It is in the fi eld of 3D computer animation visual that this change is more signifi cant, appearing regularly innovative techniques of image manipulation and “hyper-cinema” (Lamarre, 2006: 31) character’s control with deeper sense of emotions. This shift in the culture that Manovich (2006: 27) calls “photo-GRAPHICS” - and Mulvey (2007) argue that creates a new form of possessive relationship with the viewer, in that it can analyze in detail the image, it can acquire it and modify it - is one of the most important aspects in the rise of Cubbit’s (2007) “cinema of attraction”. This article delves intrinsically into the analyze of virtual character animation — particularly in the fi eld of 3D computer animation and human digital acting.

Banca de cozinha: projeto de design universal

Mais do que uma dissertação sobre o envelhecimento da população e o impacto que ela tem na sociedade, a presente tese visa documentar todo o processo projetual desenvolvido para a criação de uma banca de cozinha. Para tal foram tidas em conta, não apenas o tipo de tarefas desenvolvidas nesta zona da habitação como também os índices de fragilidade e de debilidade que os utilizadores mais envelhecidos apresentam. O facto da população envelhecida estar cada vez mais a aumentar, atingindo em alguns países valores preocupantes, associados ao facto de esses mesmos idosos atingirem cada vez mais idades mais avançadas, faz com que haja um aumento do número de pessoas incapacitadas. Assim sendo, o principal objectivo será o desenvolvimento de um projeto assente nas premissas defendidas pelo design universal. Tal projeto tentará encontrar as respostas que melhor respondam às necessidades e problemáticas, não apenas dos utilizadores mais idosos, mas do resto da população, independentemente da sua idade, estatura e condição física.

On universal central extensions of Hom-Leibniz algebras

In the category of Hom-Leibniz algebras we introduce the notion of Hom-corepresentation as adequate coefficients to construct the chain complex from which we compute the Leibniz homology of Hom-Leibniz algebras. We study universal central extensions of Hom-Leibniz algebras and generalize some classical results, nevertheless it is necessary to introduce new notions of α-central extension, universal α-central extension and α-perfect Hom-Leibniz algebra due to the fact that the composition of two central extensions of Hom-Leibniz algebras is not central. We also provide the recognition criteria for these kind of universal central extensions. We prove that an α-perfect Hom-Lie algebra admits a universal α-central extension in the categories of Hom-Lie and Hom-Leibniz algebras and we obtain the relationships between both of them. In case α = Id we recover the corresponding results on universal central extensions of Leibniz algebras.
