Arquitetura REST em smartphones Android

As grandes empresas como Google, com o Android, e a Apple, com o iOS, ajudaram a tornar a área das aplicações móveis muito apelativa e obtiveram um elevado sucesso. Com o crescimento elevado nesta área foi necessário usar uma solução que integrasse sistemas e permitisse comunicação entre aplicações diferentes, este é o caso dos Web Services, desta forma as novas aplicações podem comunicar com aplicações já existentes, e permitir que sistemas criados em plataformas diferentes comuniquem. O objetivo de um Web Service é disponibilizar uma plataforma independente de hardware e também uma plataforma que não implica estar escrita em determinada linguagem de programação. Para o acesso a um Web Service pode ser usado um protocolo ou estilo de arquitetura, nesta tese de mestrado são estudados os protocolos SOAP e a arquitectura REST, que diferem na técnica de acesso, a na sintax das mensagens trocadas. Para determinar qual dos anteriores (REST e SOAP) pode ser o mais adequado a usar no acesso a um Web Service são feitas análises a ambos e comparações entre os tempos de resposta de forma a determinar qual seria o mais vantajoso a nível de performance. O projeto que serviu como base desta tese de mestrado foi o desenvolvimento de uma aplicação de marcações em serviços beleza/saúde, a qual acede a um Web Service remoto através do REST.

Narrative Memory in Hyperfiction and Games

The aim of this paper is to address some theoretical issues concerning the narrative practice in cyberspace. From a narratological perspective it intends to clarify the functioning of time and space in storytelling. For that purpose it traces the concept(s) of memory inherited from rhetoric; the use of memory as a narrative device in traditional accounts; the adaptations imposed by hyperfiction. Using practical examples (including two Portuguese case studies - InStory 2006, and Noon 2007) it will show how narrative memory strategies can be helpful in game literacy. The main purpose is to contribute to serious game research and (trans)literary studies.

Desenvolvimento de uma aplicação Android para pacientes sob tratamento

Nos dias de hoje, as tecnologias deixaram de ser tabus para qualquer faixa etária, tor-nando-se uma necessidade emergente. Os smartphones estão entre os dispositivos mais utilizados pela população em geral no quotidiano. Adicionando aos novos estilos de vida atuais, a medicação diária também tem vindo a crescer nos últimos tempos, sendo esta utilizada em casos de hipertensão, colesterol elevado, diabetes ou outras doenças perpétuas, como também na toma de multivitamínicos, medicação para aumento de produtividade, contracetivos ou antibióticos e anti-inflamatórios em casos de constipa-ções ou gripes. Aliado a um estilo de vida célere, a toma de medicação no momento indicado facilmente é esquecida, tornando os tratamentos ineficientes. A aplicação “Hora do comprimido”, desenvolvida para dispositivos Android, permite auxiliar os utilizadores na toma da sua medicação, contínua ou temporária, facilitando o quotidiano do utilizador, viabilizando assim um tratamento completo, sem falhas nas tomas ou feitas fora de horas.

Gas tungsten arc welding of NiTi shape memory alloy

Shape memory alloys are characterized by the ability of recovering their initial shape after being deformed and by superelasticity. Since the discovery of these alloys, a new field of interest emerged not only for the scientific community but also to many industries. However, these alloys present poor machinability which constitute a constrain in the design of complex components for new applications. Thus, the demand for joining techniques able to join these alloys without compromising their properties became of great importance to enlarge the complexity of existing applications. Literature shows that these alloys are joined mainly using laser welding. In the present study, similar NiTi butt joints, were produced using TIG welding. The welds were performed in 1.5 mm thick plates across the rolling direction. A special fixture and gas assist device was designed and manufactured. Also a robot arm was adapted to accommodate the welding torch to assure the repeatability of the welding parameters. Welds were successfully achieved without macroscopic defects, such as pores and distortions. Very superficial oxidation was seen on the top surface due to insufficient shielding gas flow on the weld face. The welded joints were mechanically tested and structurally characterized. Testing methods were used to evaluate macro and microstructure, as well as the phase transformation temperatures, the mechanical single and cyclic behaviour and the shape recovery ability. Differential Scanning Calorimetry (DSC), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), microhardness measurements were techniques also used to evaluate the welded joints. A depletion in Ni in the fusion zone was seen, as well as a shift in Ms temperature. For strain values of 4% the accumulated irrecoverable strain was of about 30% and increased with the strain imposed during cycling. Nevertheless, a complete recovery of initial shape was observed when testing the shape memory effect on a dedicated device that introduces a deformation of 6.7%. That is, the welding procedure does not remove the ability of the specimens to recover their initial shape.

Writing to queens while crises proceed: In memory of Manuel Jacinto Nunes

The project of writing to a fictional Portuguese-speaking Queen on the crises proceeding since 2008 builds on Letters to Queen Elizabeth written by the British Academy and was first published in 2013. This expanded edition signals greater awareness of the complementarity between economic potential and cultural legacy in the Community of Portuguese-speaking Countries (CPLP) insofar as its members, observers and their areas of economic integration encompass the globe. The edition is dedicated to the memory of Manuel Jacinto Nunes, who supported the project as dean of the economics section at the Lisbon Academy of Science. The cover shows a Crown with nine CPLP flags as jewels in the shape of a 7 rising from the waves. The waves of lusophonia appear far gentler than Poe’s maelstrom, reproduced in the back flap. This material, inserted in the proceedings published on IICT’s 130th anniversary, is used at NOVASBE through its Center for Globalization and Governance (CG&G).

Untitled: Figurations of memory

The next pages will describe my experience and results of making connections between cognitive sciences and art; the transformations of my memories being the object of study and motivation for this process of self-discovery. The human body reacts according to innumerable neural functions and external stimuli. Neurons respond to the evocation of experienced events, building virtual images, map-like constellations sometimes fulfilled by imagination, desires or knowledge promoting in this way their constant reshaping. This document offers an insight into my recollections as matter. As matter these recollections take on different states and I hope to give you a better sense of my personal voice using my experience with glass to explore this transformation and accompanying my journey with lectures and scientific readings about the mind functions.

Application of different heuristic classes in memory-based and stimulus-based decisions

This paper studies the drivers of heuristic application in different decision types. The study compares differences in frequencies of heuristic classes' such as recognition, one-reason choice and trade-off applied in, respectively, memory-based and stimulus-based choices as well as in high and low involvement decisions. The study has been conducted online among 205 participants from 28 countries.
