Minimal computation structures for visual information applications based on printed electronics

In the early nineties, Mark Weiser wrote a series of seminal papers that introduced the concept of Ubiquitous Computing. According to Weiser, computers require too much attention from the user, drawing his focus from the tasks at hand. Instead of being the centre of attention, computers should be so natural that they would vanish into the human environment. Computers become not only truly pervasive but also effectively invisible and unobtrusive to the user. This requires not only for smaller, cheaper and low power consumption computers, but also for equally convenient display solutions that can be harmoniously integrated into our surroundings. With the advent of Printed Electronics, new ways to link the physical and the digital worlds became available. By combining common printing techniques such as inkjet printing with electro-optical functional inks, it is starting to be possible not only to mass-produce extremely thin, flexible and cost effective electronic circuits but also to introduce electronic functionalities into products where it was previously unavailable. Indeed, Printed Electronics is enabling the creation of novel sensing and display elements for interactive devices, free of form factor. At the same time, the rise in the availability and affordability of digital fabrication technologies, namely of 3D printers, to the average consumer is fostering a new industrial (digital) revolution and the democratisation of innovation. Nowadays, end-users are already able to custom design and manufacture on demand their own physical products, according to their own needs. In the future, they will be able to fabricate interactive digital devices with user-specific form and functionality from the comfort of their homes. This thesis explores how task-specific, low computation, interactive devices capable of presenting dynamic visual information can be created using Printed Electronics technologies, whilst following an approach based on the ideals behind Personal Fabrication. Focus is given on the use of printed electrochromic displays as a medium for delivering dynamic digital information. According to the architecture of the displays, several approaches are highlighted and categorised. Furthermore, a pictorial computation model based on extended cellular automata principles is used to programme dynamic simulation models into matrix-based electrochromic displays. Envisaged applications include the modelling of physical, chemical, biological, and environmental phenomena.

Design of New Materials for Passive Vibration Control

The objective of this contribution is to extend the models of cellular/composite material design to nonlinear material behaviour and apply them for design of materials for passive vibration control. As a first step a computational tool allowing determination of optimised one-dimensional isolator behaviour was developed. This model can serve as a representation for idealised macroscopic behaviour. Optimal isolator behaviour to a given set of loads is obtained by generic probabilistic metaalgorithm, simulated annealing. Cost functional involves minimization of maximum response amplitude in a set of predefined time intervals and maximization of total energy absorbed in the first loop. Dependence of the global optimum on several combinations of leading parameters of the simulated annealing procedure, like neighbourhood definition and annealing schedule, is also studied and analyzed. Obtained results facilitate the design of elastomeric cellular materials with improved behaviour in terms of dynamic stiffness for passive vibration control.

Famílias de pessoas com síndromes psicóticas : análise dimensional e avaliação da efectividade de uma intervenção em grupos para familiares

RESUMO:Enquadramento teórico Nas famílias das pessoas com síndromas psicóticas, a história natural da prestação de cuidados informais é ainda pouco conhecida. Independentemente disso, o impacto sobre os cuidadores tem sido alvo de intervenções familiares (IF) psicoeducativas. Não esquecendo que contextos clínicos diferentes, como é o caso das demências, exibem, nas famílias, especificidades a explorar, torna-se crucial aperfeiçoar métodos para avaliação de grupos de risco e estudo da efectividade das IF. As intervenções em grupos para familiares (IGF) são exequíveis e cobrem parte das necessidades das famílias. Ao invés de outras IF, falta evidência inequívoca de que as IGF influenciem o prognóstico da esquizofrenia (diminuindo as taxas de recaída ou melhorando o funcionamento dos doentes). Em Portugal, são praticamente inexistentes dados sobre avaliação de IGF. O estudo FAPS (FAmílias de Pessoas com PSicose) teve como objectivos: estudar a adesão a uma IGF, avaliar a efectividade desta e estudar prospectivamente uma coorte de familiares que não tivessem aderido (considerando dimensões da experiência de cuidar e preditores putativos: suporte social, coping, sentido de coerência-SOC, covariáveis clínico-funcionais do doente). Adicionalmente, intentou a validação do Involvement Evaluation Questionnaire, versão europeia (IEQ-EU), numa população portuguesa.
