Convergence of the Crank-Nicolson-Galerkin finite element method for a class of nonlocal parabolic systems with moving boundaries
The aim of this paper is to establish the convergence and error bounds to the
fully discrete solution for a class of nonlinear systems of reaction-diffusion
nonlocal type with moving boundaries, using a linearized
Crank-Nicolson-Galerkin finite element method with polynomial approximations of
any degree. A coordinate transformation which fixes the boundaries is used.
Some numerical tests to compare our Matlab code with some existing moving
finite elements methods are investigated
Body composition and blood parameters of newborn piglets from Alentejano and conventional (Large White × Landrace) genotype
This study aimed to compare the body composition and some blood parameters [(glucose, albumin and insulin-like
growth factor 1 (IGF-1)] of newborn piglets farrowed by unselected Alentejano (AL) or conventional genotype [Large-
White Landrace (LL)]. Carcasses (12 of each genotype) and blood samples were obtained from a total of 34 litters (18
AL, 16 LL). Gestation length was 4d shorter in AL sows compared with LL sows. When adjusted for birth weight,
carcasses of AL piglets showed higher percentages of dry matter (P < 0.05) and crude protein (P < 0.01) and tended to
have higher lipid content (P = 0.091) than carcasses of LL piglets. Relative to body weight, the AL piglets had heavier
livers (P < 0.05) than LL piglets but glycogen content was similar in both genotypes. Longissimus dorsi muscle of AL
piglets contained more protein (P < 0.01), but glycogen, DNA and RNA contents were similar in both genotypes. The
blood from the AL piglets had higher levels of glucose (P < 0.01), albumin (when adjusted for birth weight) (P<0.05)
and IGF-1 (P < 0.05) than blood from the LL piglets. On the bases of body composition and studied blood parameters,
AL piglets seem to be more mature at birth than LL piglets despite a shorter gestation lenght
Beyond application-led research in pervasive display systems
This position paper argues that more research is needed into identifying key abstractions and reference criteria for multi-purpose display systems. This would enable research in this area to go beyond the development of specific applications and move towards enabling infrastructures that could serve the needs of multiple applications.Fundação para a Ciência e Tecnologia (FCT) - POSC/EIA/58832/2004FEDER - POS_Conheciment
A Web portal for situated Interaction
The combination between ubiquitous computing environments and ambient displays enables a broad range of new scenarios for situated interaction. In this paper, we describe our web based approach for situated displays. The concept of situated portal is introduced as a web portal that is targeted for presentation at a specific situation and that is based on interaction metaphors that are radically different from hypertext and oint-and-click interactions. We have created a prototype in which a situated portal is used for managing content presentation and user interaction at two different displays.
This prototype has provided an important proof-of-concept and has allowed us to gain considerable feedback on its usage and scientific challenges, based on which we will now deploy a new large-scale prototype where some of the key issues will be addressed by a multi-disciplinary team
Desenvolvimento de recursos de design em pequenas empresas da indústria automóvel : uma abordagem metodológica
ABSTRACT: This paper reflects part of a broader investigation on the
development of methodologies to identify, value and manage design
capabilities in order to create a sustainable competitive advantage. With
the automotive industry and smaller supplier Portuguese companies as
background, this paper explores the resource-based view theory (RBV)
and the dynamic capabilities theory as a theoretical construct for a
further development of research tools.
In the automotive industry, OEM (Original Equipment Manufacturers)
continue to control the overall design of the vehicle, as part of the ability
to manage the offer portfolio and brand communication. However, the
industry have been moving towards an increasing participation of smaller
suppliers in product development processes, pushed towards capabilities’
development as a requirement to continue competitive in the OEM’s
suppliers network.
The role of design and design management capabilities have been
explored as strategic resources or core competencies. However, Design is
not typically found in smaller supplier firms as resource (as opposed to
Design studios in larger companies) but found as a process in resourcecapability
combinations, establishing the need for a new research
approach. Therefore, the RBV is a tool to value the design process as a
sustained competitive advantage. The RBV conceptualizes a framework
to determine or identify the strategic resources available or needed
within a company. At these lenses, the basis for a sustainable competitive
advantage lies in the application of the bundle of valuable resources
identified and at the firm's disposal and the combinations with its
capabilitiesEste artigo reflete parte de uma investigação mais ampla sobre
o desenvolvimento de metodologias para identificar, valorizar e gerir os
recursos de design, com o objetivo de criar uma vantagem competitiva
sustentável. Com a indústria automóvel e as pequenas empresas
portuguesas fornecedoras como pano de fundo, este artigo explora a
teoria da Resource Based View (RBV) e a teoria das Dynamic
Capabili_es (DCT) como um construto teórico para o desenvolvimento de
ferramentas de investigação.
Na indústria automóvel, os OEM (fabricantes de equipamentos originais)
continuam a controlar o design geral do veÃculo, como parte da
capacidade de gestão do seu portfólio assim como a comunicação de
marca. No entanto, o setor tem seguido um caminho para uma
participação crescente de fornecedores menores nos processos de
desenvolvimento de produto, impulsionados para o desenvolvimento de
capacidades como requisito de competitividade na rede de fornecedores
dos OEM.
O papel dos recursos do design e da gestão do design foram já explorados
como recurso estratégicos ou competências fundamentais. No entanto, o
Design não é normalmente encontrado em empresas de menor dimensão
como recurso (em oposição aos estúdios de Design em empresas
maiores), mas sim como um processo de combinações de diferentes
capacidades e recursos, estabelecendo a necessidade de uma nova
abordagem de pesquisa. Portanto, a RBV é uma ferramenta que visa a
valorização do processo de design como uma vantagem competitiva
sustentada. A RBV concetualiza uma estrutura para determinar ou
identificar os recursos estratégicos disponÃveis ou necessários dentro de
uma empresa. Deste ponto de vista, a base para uma vantagem
competitiva sustentável está na aplicação do conjunto de recursos
valiosos identificados e à disposição da empresa em forma de
combinações das suas diferentes capacidades e recursos.info:eu-repo/semantics/publishedVersio
