Boundary Conditions as Mass Generation Mechanism for Real Scalar Fields

We consider the effects of homogeneous Dirichlet's boundary conditions on two infinite parallel plane surfaces separated by a small distance {\it a}. We find that although spontaneous symmetry breaking does not occur for the theory of a massless, quartically self-interacting real scalar field, the theory becomes a theory of a massive scalar field.Comment: 10 pages; added remarks for section 3, references removed and others added, second term of Eq.(15) change

Computational Results on Membership in R&D Cooperation Networks: To Be or Not To Be in a Research Joint Venture

In this study, we analyze firms’ membership in R&D (Research and Development) cooperation networks. Our main research hypothesis is that the membership in cooperation networks is related to the degree of the knowledge spillover. The approach focus on both cost symmetry and cost asymmetry. For that purpose, our work is developed in two tasks: we first develop an analytical model with three stages: in the first, firms decide whether to participate in a cooperative research network; in the second they simultaneously choose the level of R&D output, and finally firms choose the level of output through Cournot competition under both cost symmetry and cost asymmetry. Then we proceed with computational simulations in order to verify our hypothesis. From our results, we were able to conclude that cooperation leads to an improvement on RJV firms’ position in the market as it allows them to produce more than others with the same production conditions. Additionally, cooperating firms have to spend fewer resources on research, which turns the network a tremendous success on the productive efficiency level.R&D, networks, spillover, simulation, RJV

Conceição Rosa Pereira & Cª., Lda : Luis Onofre : strategic development for a Portuguese luxury brand

How can a Portuguese luxury brand stand out in the competitive footwear industry? Which internationalization strategies should the company uses and what are the most important resources that will sustain the firm competitive advantage in this market? Conceição Rosa Pereira & Cª., Lda is a Portuguese company that operates in the footwear industry and its most recognized by his own shoe brand – Luis Onofre. Besides operating in the footwear industry by commercializing the brand Luis Onofre the company also takes care of production for private labels. This dissertation purposes a journey into the company history to understand the key milestones and to get to know the position of the company in the recent years. There will be the opportunity to comprehend the differentiation factors from the firm and to analyze the resources and the capabilities that enable to firm to have competitive advantages.Como é que uma empresa de luxo Portuguesa se pode sobressair no competitivo mercado do calçado? Que estratégias de internacionalização deve utilizar e quais os recursos mais importantes para obter e sustentar as vantagens competitivas neste mercado? Conceição Rosa Pereira & Cª., Lda é uma empresa portuguesa que opera na industria do calçado de luxo sendo que é mais reconhecida por fabricar e comercializar a sua marca Luis Onofre. Para além da marca Luis Onofre a empresa também fabrica sapatos para outras marcas privadas através da sua empresa irmã Luis Onofre Internacional. Esta dissertação propõe uma viagem ao longo da historia da empresa de modo a perceber os momentos decisivos no sucesso da empresa e também para perceber a evolução da empresa desde a sua criação. Haverá oportunidade para compreender e analisar os factores diferenciadores que contribuíram para que a empresa fosse bem-sucedida e quais os recursos e capacidades que a empresa possui que lhe permitem gerar vantagens competitivas

Looking at the other: Museological narrative on diversity in the era of globalization

O artigo apresenta os resultados parciais duma investigação em curso sobra narrativas museológicas sobre o reconhecimento da diversidade cultural. A partir duma análise sobre os processos de construção a ideia do outro em diferentes exposições em diverso museus, na Península Ibérica, no Brasil e em Moçambique, procuramos identificar os processos narrativos hegemónicos e os processos de silenciamento e esquecimento da diferença. Argumentamos, a partir do discurso identitário português, que sem a inclusão das narrativas sobre a diversidade, a cultura hegemónica não está a fornecer uma cartografia mental adequada para orientar e enfrentar a construção de inovação social nos museus.This article presents the partial results of a research about the recognition of cultural diversity on museum narratives. From an analysis of the formation of alterity on different exhibitions in several museums in the Iberian Peninsula, Brazil and Mozambique, we sought to identify the hegemonic narrative processes and the processes of silencing and forgetting the difference. We argue, from the Portuguese cultural speech that without the inclusion of narratives about the diversity culture does not provide a guiding mapping to address innovation

Automotive gestures recognition based on capacitive sensing

Dissertação de mestrado integrado em Engenharia Eletrónica Industrial e ComputadoresDriven by technological advancements, vehicles have steadily increased in sophistication, specially in the way drivers and passengers interact with their vehicles. For example, the BMW 7 series driver-controlled systems, contains over 700 functions. Whereas, it makes easier to navigate streets, talk on phone and more, this may lead to visual distraction, since when paying attention to a task not driving related, the brain focus on that activity. That distraction is, according to studies, the third cause of accidents, only surpassed by speeding and drunk driving. Driver distraction is stressed as the main concern by regulators, in particular, National Highway Transportation Safety Agency (NHTSA), which is developing recommended limits for the amount of time a driver needs to spend glancing away from the road to operate in-car features. Diverting attention from driving can be fatal; therefore, automakers have been challenged to design safer and comfortable human-machine interfaces (HMIs) without missing the latest technological achievements. This dissertation aims to mitigate driver distraction by developing a gestural recognition system that allows the user a more comfortable and intuitive experience while driving. The developed system outlines the algorithms to recognize gestures using the capacitive technology.Impulsionados pelos avanços tecnológicos, os automóveis tem de forma continua aumentado em complexidade, sobretudo na forma como os conductores e passageiros interagem com os seus veículos. Por exemplo, os sistemas controlados pelo condutor do BMW série 7 continham mais de 700 funções. Embora, isto facilite a navegação entre locais, falar ao telemóvel entre outros, isso pode levar a uma distração visual, já que ao prestar atenção a uma tarefa não relacionados com a condução, o cérebro se concentra nessa atividade. Essa distração é, de acordo com os estudos, a terceira causa de acidentes, apenas ultrapassada pelo excesso de velocidade e condução embriagada. A distração do condutor é realçada como a principal preocupação dos reguladores, em particular, a National Highway Transportation Safety Agency (NHTSA), que está desenvolvendo os limites recomendados para a quantidade de tempo que um condutor precisa de desviar o olhar da estrada para controlar os sistemas do carro. Desviar a atenção da conducção, pode ser fatal; portanto, os fabricante de automóveis têm sido desafiados a projetar interfaces homemmáquina (HMIs) mais seguras e confortáveis, sem perder as últimas conquistas tecnológicas. Esta dissertação tem como objetivo minimizar a distração do condutor, desenvolvendo um sistema de reconhecimento gestual que permite ao utilizador uma experiência mais confortável e intuitiva ao conduzir. O sistema desenvolvido descreve os algoritmos de reconhecimento de gestos usando a tecnologia capacitiva.It is worth noting that this work has been financially supported by the Portugal Incentive System for Research and Technological Development in scope of the projects in co-promotion number 036265/2013 (HMIExcel 2013-2015), number 002814/2015 (iFACTORY 2015-2018) and number 002797/2015 (INNOVCAR 2015-2018)
