Relentless patterns the immersive interior

What happens when patterns become all pervasive? When pattern contagiously corrupts and saturates adjacent objects, artefacts and surfaces; blurring internal and external environment and dissolving any single point of perspective or static conception of space. Mark Taylor ruminates on the possibilities of relentless patterning in interior space in both a historic and a contemporary context.

Diagramming the interior

Mark Taylor's new essay assesses the impact of the diagram on interior design from the late 19th century to the present. Taylor identifies the pop-cultural discourse of advice writing in both books and magazines as a starting point for his analysis. Drawing on diverse sources, his analysis focuses on texts relating to the dynamics of use and flexibility by Catherine Beecher, Harriet Beecher Stowe, Melusina Fay Peirce, Mary Haweis and Christine Frederick among others. The examples in these texts use the home, domestic housekeeping and kitchens as the sites and practices of intervention through which interior design innovations can be enacted. Taylor's analysis identified the innovations in both the social and the political aspects of space and the critique of static space behind these seemingly amateurish and innocuous texts. Identifying these contributions as early precursors of Modernism's open-plan and flexible, dynamic spaces, Taylor also interprets them with a critical concern for the oppositions and hierarchies that can exist in spatial design, and which are the hallmarks of recent Postmodern, phenomenological approaches to interior design and its theorisations. The progressive and subversive "paradigms for living" implicit in these diagrams can be argued to present a model of greater economic, social and political equality as well as representing a more balanced set of power relations in the home. Progressing through the 20th century to the present, Taylor's analysis shifts byond the dressed body and on to the more intimate rituals of the revealed body to further examine how diagrams of the interior, and the interior as a set of diagrams, are also mediators, sites and grounds for the design of social and sexual intimacy. Through a consideration of the link between design, indentity and intimacy (whether of the invisible, fashioned or sexualised body), the diagrms of interiors are reconfigured as radical and critical tools for an animate, material and emancipatory "redressing" of the balance between the body, identity, sexuality, gender, function, mis(use), aesthetics and the interior.

The French polisher and the unsentimental interior

In January 2011 a swollen Brisbane River broke its banks flooding riverside houses and buildings. The river’s water spread and rose up through storm water drains inundating some 20 000 houses in low-lying land. As the water receded those residents affected by the floods returned to their homes to assess the damage. While some people breathed a sigh of relief others were devastated by the overwhelming damage to their homes and personal belongings. Over the next few weeks the landscape of Brisbane was altered not merely by the mud and debris left by the torrent of water, but by the piles of domestic contents occupying Brisbane streets. Beds, toys, cabinets, plasterboard, tiles and household furniture lined curbsides waiting for collection. Later they would accumulate in public parks and sports centres to await disposal, momentarily creating an unsettling landscape of discarded domestic interiors. While most houses remained standing the heart breaking repercussions were evident in their interiority. Thousands of volunteers flocked to help those affected by the floods to purge the damage left by the water – removing wall and floor linings, discarding furniture and spoilt belongings. In her paper on Hurricane Katrina, Julieanna Preston wrote, ‘What anthropological evidence would we find as we followed their migration – heaps left by the side of the road, the physical weight overcoming the personal value…’ For many of the post flood restored homes and buildings entire interiors have been replaced, eradicating any trace of the significant event that disturbed them only months earlier. There were artifacts that would have survived the floods - furniture of solid timber – these were discarded and with them the patina that marked an important event in history. The patina is beyond technological reproducibility, and as Walter Benjamin writes, this being the whole premise of genuineness. It is the role of the French Polisher to maintain the true wear of the artefact for it is the patina that is most valuable in its ability to narrate the history of a piece. In 2012 two separate exhibitions in Brisbane will take place to display a selected collection of flood-damaged artefacts. This orchestrated way to commemorate the damage left by floods may be a method to compensate for the haste in which the damage was purged from the city. This need for exhibiting damaged artifacts illustrates Andreas Huyssen’s point that "…today memory is understood as a mode of re-presentation and as belonging to the present." This research looks at the dying trade of the French Polisher through conversations and a visual study of flood damaged furniture. The research also investigates the personal loss of artifacts through intimate stories shared by flood victims. This paper seeks to understand why so much was discarded and celebrate what remains.

Heat transfer with solid liquid phase change initiating at a point in a semi infinite mold

Short-time analytical solutions of temperature and moving boundary in two-dimensional two-phase freezing due to a cold spot are presented in this paper. The melt occupies a semi-infinite region. Although the method of solution is valid for various other types of boundary conditions, the results in this paper are given only for the prescribed flux boundary conditions which could be space and time dependent. The freezing front propagations along the interior of the melt region exhibit well known behaviours but the propagations along the surface are of new type. The freezing front always depends on material parameters. Several interesting results can be obtained as particular cases of the general results.

Study of fracture behaviour of bond coats on nickel superalloy by three-point bending of microbeams

A microbeam testing geometry is designed to study the variation in fracture toughness across a compositionally graded NiAl coating on a superalloy substrate. A bi-material analytical model of fracture is used to evaluate toughness by deconvoluting load-displacement data generated in a three-point bending test. It is shown that the surface layers of a diffusion bond coat can be much more brittle than the interior despite the fact that elastic modulus and hardness do not display significant variations. Such a gradient in toughness allows stable crack propagation in a test that would normally lead to unstable fracture in a homogeneous, brittle material. As the crack approaches the interface, plasticity due to the presence of Ni3Al leads to gross bending and crack bifurcation.

Distributed Storage Codes With Repair-by-Transfer and Nonachievability of Interior Points on the Storage-Bandwidth Tradeoff

Regenerating codes are a class of recently developed codes for distributed storage that, like Reed-Solomon codes, permit data recovery from any subset of k nodes within the n-node network. However, regenerating codes possess in addition, the ability to repair a failed node by connecting to an arbitrary subset of d nodes. It has been shown that for the case of functional repair, there is a tradeoff between the amount of data stored per node and the bandwidth required to repair a failed node. A special case of functional repair is exact repair where the replacement node is required to store data identical to that in the failed node. Exact repair is of interest as it greatly simplifies system implementation. The first result of this paper is an explicit, exact-repair code for the point on the storage-bandwidth tradeoff corresponding to the minimum possible repair bandwidth, for the case when d = n-1. This code has a particularly simple graphical description, and most interestingly has the ability to carry out exact repair without any need to perform arithmetic operations. We term this ability of the code to perform repair through mere transfer of data as repair by transfer. The second result of this paper shows that the interior points on the storage-bandwidth tradeoff cannot be achieved under exact repair, thus pointing to the existence of a separate tradeoff under exact repair. Specifically, we identify a set of scenarios which we term as ``helper node pooling,'' and show that it is the necessity to satisfy such scenarios that overconstrains the system.

Enfrentando a violência contra a mulher: uma experiência pioneira no interior do Estado do Rio de Janeiro

A pesquisa analisou a estratégia adotada por uma Organização Não Governamental feminista do interior do Estado do Rio de Janeiro, o Ser Mulher, no enfrentamento da violência contra a mulher. A estratégia compreende a implantação de um Serviço telefônico anônimo, denominado Disque-Mulher e a composição da Rede Multisetorial de Atendimento às Mulheres Vítimas de Violência (REMUV). A experiência do Serviço é descrita a partir das diferentes metodologias de atendimento e registro dos relatos telefônicos. A análise buscou identificar, no banco de dados resultante dos registros telefônicos, a percepção e a atribuição de significados das usuárias do Disque-Mulher em relação as suas vivências de violência conjugal à luz da literatura feminista brasileira contemporânea. Esta dissertação alinhou-se a um grupo de pesquisadoras que focaram a atenção em descrever e refletir sobre as representações femininas acerca da violência retratadas através da divisão das estudiosas que representam a mulher como vítima ou cúmplice da violência e as que salientam a não universalidade da experiência feminina diante das agressões, valorizando aspectos singulares das mulheres agredidas. Foram utilizadas três fontes de dados: os 1274 registros telefônicos que compõem um banco de dados denominado geral, delineando o perfil sócio-econômico cultural das usuárias e os 413 registros do banco de dados específico, que faz parte do geral e foi montado após as mudanças na forma de realizar o registro e que contém informações de caráter qualitativo, permitindo problematizar os impasses das usuárias frente ao desejo expresso de separarem-se de relações conjugais violentas. Além disso, foram realizadas entrevistas e supervisões gravadas e transcritas, com as plantonistas do Disque-Mulher visando apreender suas percepções sobre os limites e possibilidades de utilização do atendimento telefônico anônimo como estratégia de enfrentamento da violência contra a mulher. Além de salientar para a necessidade de uma constante articulação entre ONGs e poder público, a pesquisa aponta também para a importância de confluir esforços em busca de categorização e sistematização das informações obtidas em serviços semelhantes ao Disque- Mulher, cujo objeto de trabalho é a escuta de fenômenos complexos e multifacetados como a violência e o acesso a direitos. Além de categorizar o motivo principal dos telefonemas há um questionamento em que medida os impasses das usuárias frente ao desejo de separarem-se estariam relacionados a tensões entre a subjetivação feminina e as mudanças sociais, que permitiram às mulheres ampliar sua autonomia.

The device consists of a floating flap or paddle facing the waves and reacting against them through an interior moving mass in an enlarged section at the bottom of the buoy.

Advanced energy efficient coordinated multi-point transmission for OFDMA

The ever-growing energy consumption in mobile networks stimulated by the expected growth in data tra ffic has provided the impetus for mobile operators to refocus network design, planning and deployment towards reducing the cost per bit, whilst at the same time providing a signifi cant step towards reducing their operational expenditure. As a step towards incorporating cost-eff ective mobile system, 3GPP LTE-Advanced has adopted the coordinated multi-point (CoMP) transmission technique due to its ability to mitigate and manage inter-cell interference (ICI). Using CoMP the cell average and cell edge throughput are boosted. However, there is room for reducing energy consumption further by exploiting the inherent exibility of dynamic resource allocation protocols. To this end packet scheduler plays the central role in determining the overall performance of the 3GPP longterm evolution (LTE) based on packet-switching operation and provide a potential research playground for optimizing energy consumption in future networks. In this thesis we investigate the baseline performance for down link CoMP using traditional scheduling approaches, and subsequently go beyond and propose novel energy e fficient scheduling (EES) strategies that can achieve power-e fficient transmission to the UEs whilst enabling both system energy effi ciency gain and fairness improvement. However, ICI can still be prominent when multiple nodes use common resources with di fferent power levels inside the cell, as in the so called heterogeneous networks (Het- Net) environment. HetNets are comprised of two or more tiers of cells. The rst, or higher tier, is a traditional deployment of cell sites, often referred to in this context as macrocells. The lower tiers are termed small cells, and can appear as microcell, picocells or femtocells. The HetNet has attracted signiffi cant interest by key manufacturers as one of the enablers for high speed data at low cost. Research until now has revealed several key hurdles that must be overcome before HetNets can achieve their full potential: bottlenecks in the backhaul must be alleviated, as well as their seamless interworking with CoMP. In this thesis we explore exactly the latter hurdle, and present innovative ideas on advancing CoMP to work in synergy with HetNet deployment, complemented by a novel resource allocation policy for HetNet tighter interference management. As system level simulator has been used to analyze the proposed algorithm/protocols, and results have concluded that up to 20% energy gain can be observed.

Efeitos da injunção da base nas orientações interior e exterior e nas coordenadas do espaço objeto em imagens obtidas com a estéreo vídeo-câmara de um sistema móvel de mapeamento

In general, a land-based mobile mapping system is featured by a vehicle with a pair of video cameras mounted on the top and positioning and navigation sensors loaded in the vehicle. Considering the pair of video cameras mounted on the roof of the vehicle as a stereo camera pointing forward with both optical axes parallel to each other and orthogonal to the stereo base, whose length is 0.94 m, this paper aims at analyzing the interior and exterior camera orientation and the object point coordinates estimated by phototriangulation when the length constraint related to the stereo base is considered or not. The results show that the stereo base constraint has effect ouver the convergence estimation, but does it neither improves the object point coordinate estimation at significance level of 5% and nor it influences the interior orientation parameters. Finally, it has been noticed that the optical axes are not truly parallel to each other and orthogonal to the stereo base. Additionally, it has been observed that there is a convergence of approximately 0.5 degrees in the optical axes and they are not in the same plane (approximately 0.8 degrees deviation).

Análise comparativa da assembléia de aves em dois remanescentes florestais no interior do Estado de São Paulo, Brasil

Realizou-se o levantamento quantitativo e qualitativo da comunidade de aves de dois fragmentos de floresta estacional semidecídua no interior do estado de São Paulo de julho de 2004 a julho de 2005. Para o estudo quantitativo utilizou-se da metodologia de Pontos de Escuta. Foram analisados os índices de diversidade e de freqüência de ocorrência dessa comunidade. O levantamento qualitativo registrou 181 espécies na Fazenda Rio das Pedras - FRP (Itapetininga, 350 ha) e 126 espécies na Fazenda Santa Maria II - FSM (Buri, 480 ha), enquanto que o levantamento quantitativo registrou a presença de 73 espécies em 988 contatos e 64 espécies em 1019 contatos para FRP e FSM, respectivamente. O índice pontual de abundância (IPA) variou de 0,01 (1 contato) a 1,32 (132 contatos), para FRP e na FSM variou entre 0,01 (1 contato) a 0,97 (97 contatos). A diversidade do fragmento da FRP foi de H = 3,04 e na FSM de H = 2,85 onde a eqüitatividade em ambas áreas foi de 0,91. A comunidade de aves nos fragmentos estudados mostrou o mesmo padrão encontrado em outros fragmentos de floresta estacional semidecídua de tamanhos relativos. As categorias alimentares mais representativas nos dois remanescentes foram insetívoras (53% na FSM e 50% na FRP) e frugívoras (23% na FSM e 26% na FRP). Dentre os insetívoros, destacaram-se as famílias Tyrannidae na FSM e Thamnophilidae na FRP. Tanto na FSM como na FRP os insetívoros de sub-bosque foram mais representativos (53% e 51,4% respectivamente), seguidos pelos frugívoros de sub-bosque (50%) na FSM e frugívoros de copa (52,6%) na FRP. A importância do estudo de comunidade de aves esta ligada à elaboração do plano de manejo e conservação das áreas naturais.

Avifauna da Estação Ecológica dos Caetetus, interior de São Paulo, Brasil

A Estação Ecológica dos Caetetus possui um dos maiores remanescentes de mata estacional semidecídua ainda presentes no Estado de São Paulo. Poucos estudos foram realizados nessa localidade, extremamente importante no que diz respeito às aves da Mata Atlântica do interior do Estado. Para caracterizar a avifauna da estação com dados recentes e contribuir com novos registros, foi realizado um levantamento da avifauna utilizando-se o método de Pontos de Escuta entre outubro de 2005 e dezembro de 2006. Foram registradas 226 espécies enquanto diversos autores registraram outras 68, para um total de 293. Muitas espécies são endêmicas da Mata Atlântica ou do Cerrado e algumas são ameaçadas no Estado, justificando a existência dessa unidade de conservação e provando a necessidade de inventários em longo prazo e da preservação de fragmentos de mata estacional semidecídua nativa.

Resonance and chaos .1. First-order interior resonances

Analytical models for studying the dynamical behaviour of objects near interior, mean motion resonances are reviewed in the context of the planar, circular, restricted three-body problem. The predicted widths of the resonances are compared with the results of numerical integrations using Poincare surfaces of section with a mass ratio of 10(-3) (similar to the Jupiter-Sun case). It is shown that for very low eccentricities the phase space between the 2:1 and 3:2 resonances is predominantly regular, contrary to simple theoretical predictions based on overlapping resonance. A numerical study of the 'evolution' of the stable equilibrium point of the 3:2 resonance as a function of the Jacobi constant shows how apocentric libration at the 2:1 resonance arises; there is evidence of a similar mechanism being responsible for the centre of the 4:3 resonance evolving towards 3:2 apocentric libration. This effect is due to perturbations from other resonances and demonstrates that resonances cannot be considered in isolation. on theoretical grounds the maximum libration width of first-order resonances should increase as the orbit of the perturbing secondary is approached. However, in reality the width decreases due to the chaotic effect of nearby resonances.
