Criação de um Microtesauro na área da Dança

Este trabalho de Investigação teve como objetivo a construção de um microtesauro na área da Dança. Face à inexistência de um Tesauro especializado na área da Dança, quer a nível nacional, quer internacional, e para dar resposta às necessidades de uma recuperação mais eficaz de informação nas Unidades Documentaisi Especializadas em Dança. Neste caso, em particular, no Centro de Informação e Documentação (CDI) da Escola Superior de Dança (ESD). Percebeu-se que a construção deste microtesauro, tendo em conta as normas nacionais e internacionais para o efeito. No âmbito das funções desempenhadas no CDI foi identificada a necessidade de existir um instrumento de Linguagem Documental adequado, que permitisse nas Pesquisas bibliográficas, recuperar por Assunto os documentos existentes na Base de Dados. A Pesquisa Bibliográfica, apenas disponível por Título e por Autor, veio a revelar-se insuficiente, e a impossibilidade de pesquiasr os documentos por Assunto traduzia-se numa carência crescente dos utilizadores e do próprio Serviço. A Metodologia seguida para a construção deste Microtesauro, teve como base uma lista de Termos de Indexação construída a partir da análise de uma amostra de 125 monografias e a consulta de várias fontes de informção (monografias e obras de referência, linguagens documentais, e entrevistas informais a docentes da ESD). A análise, quantificação e qualificação dos termos que constituem este microtesauro teve o acompanhamento, avaliação e adequação contínua por parte de alguns docentes da ESD, investigadores e especialistas em Dança. A Dança, enquanto objeto de exploração teórica, revela-se uma disciplina transversal a várias áreas do conhecimento que, agrupadas em classes, correspondem a 8 áreas do saber, relacionadas com a Dança, tendo em consideração as temáticas do espólio documental do CDI e as matérias lecionadas nas Unidades Curriculares dos cursos de Licenciatura e Mestrados da ESD. O microtesauro na área da Dança, que resulta do nosso trabalho de investigação, é constituído por Descritores, Não-Descritores, e suas relações de equivalência hierárquicas e associativas, apresentando-se no final deste trabalho, em apêndice, devido à sua dimensão. O mesmo resulta de um processos de construção individual, inicialmente elaborado de forma manual e posteriormente transposto para um Software Documental CDS/ISIS para Windows, que veio agilizar a estruturação do microtesauro. Este microtesauro na área da Dança, em Língua Portuguesa, constitui um importante contributo para as Bibliotecas e Centros de Documentação que detêm documentação nesta área específica, dado colmatar uma lacuna existente neste domínio do conhecimento.

Temporally stable feature clusters for maritime object tracking in visible and thermal imagery

This paper describes a new approach to detect and track maritime objects in real time. The approach particularly addresses the highly dynamic maritime environment, panning cameras, target scale changes, and operates on both visible and thermal imagery. Object detection is based on agglomerative clustering of temporally stable features. Object extents are first determined based on persistence of detected features and their relative separation and motion attributes. An explicit cluster merging and splitting process handles object creation and separation. Stable object clus- ters are tracked frame-to-frame. The effectiveness of the approach is demonstrated on four challenging real-world public datasets.

Historiografisk metafiktion och faktion : Romantikens berättelse om den förstenade gruvdrängen Fet-Mats i två postmoderna versioner

Fet-Mats är den gruvdräng som omkom och försvann i en rasolycka i Falu koppargruva under 1670-talet och vars kropp upptäcktes välbevarad, med fortfarande ungdomligt utseende, mer än fyra årtionden senare 1719. Han igenkändes då av sin trolovade - nu en gammal gumma. På grund av den märkligt bibehållna kroppen och det hisnande ögonblick då den åldrade kvinnan återsåg sin ungdoms kärlek, blev Fet-Mats och hans historia snabbt känd, även internationellt. Den spreds under 1800- och 1900-talen i Europa som novell och poesi, dramatik och opera. Även idag berättas historien om Fet-Mats både utomlands och i Sverige. Intresset för historien är rentav i växande. Orsaken härtill är omdaningen under senare år av Falu gruva från storindustri till musealt världsarv, från malmbrytning till turistorienterad upplevelseindustri. Fet-Mats-berättelsen bildar centrum i denna upplevelseindustri. I mitt paper diskuteras detta förhållande samt den nutida Fet-Mats-epikens karakteristika i ett semiotiskt, narratologiskt och tematiskt perspektiv. Jag finner bl.a. att Fet-Mats-berättandet idag, på ett annat sätt än tidigare, äger en flermedial karaktär och formulerar det postmoderna tillståndets centrala tematik: representationens kris. Jag fokuserar särskilt på två berättelser med anknytning till Fet-Mats-motivet: Julian Barnes historiografiska metafiktion The Story of Mats Israelson (2004) och det dramadokumentära seriealbumet Fet-Mats: en gruvdrängs hemska öde (2005).

A method and its optimal parameters for the measurement of mass transfer coefficient in heat treatment furnaces

The mass transfer coefficient is an important kinetic factor to control the thermo-chemical treatment processes of metals and alloys. More importantly, the mass transfer coefficient is different at different surface positions of a metallic part treated, which depends on the dynamic characteristics of the atmosphere close to the treated surface. Understanding the local mass transfer coefficient would be significant to approach the expected physical and mechanical properties of treated surfaces. In this paper, a reverse method was proposed to measure the mass transfer coefficient at component surface and the diffusivity in metal during heat treatment. The methodology of the reverses method and the optimal parame-ters are discussed in some detail. This method was successfully used to determine the car-bon transfer coefficient at the surface of a part in a carburizing furnace and carbon diffusiv-ity from the carbon distribution within the diffusion layer.

Além da Mediocridade

Multicamadas Ferromagnéticas Nanométricas Periódicas e Quasiperiódicas

We present a study of nanostructured magnetic multilayer systems in order to syn- thesize and analyze the properties of periodic and quasiperiodic structures. This work evolved from the deployment and improvement of the sputtering technique in our labora- tories, through development of a methodology to synthesize single crystal ultrathin Fe (100) films, to the final goal of growing periodic and quasiperiodic Fe/Cr multilayers and investi- gating bilinear and biquadratic exchange coupling between ferromagnetic layer dependence for each generation. Initially we systematically studied the related effects between deposition parameters and the magnetic properties of ultrathin Fe films, grown by DC magnetron sput- tering on MgO(100) substrates. We modified deposition temperature and film thickness, in order to improve production and reproduction of nanostructured monocrystalline Fe films. For this set of samples we measured MOKE, FMR, AFM and XPS, with the aim of investi- gating their magnocrystalline and structural properties. From the magnetic viewpoint, the MOKE and FMR results showed an increase in magnetocrystalline anisotropy due to in- creased temperature. AFM measurements provided information about thickness and surface roughness, whereas XPS results were used to analyze film purity. The best set of parame- ters was used in the next stage: investigation of the structural effect on magnetic multilayer properties. In this stage multilayers composed of interspersed Fe and Cr films are deposited, following the Fibonacci periodic and quasiperiodic growth sequence on MgO (100) substrates. The behavior of MOKE and FMR curves exhibit bilinear and biquadratic exchange coupling between the ferromagnetic layers. By computationally adjusting magnetization curves, it was possible to determine the nature and intensity of the interaction between adjacent Fe layers. After finding the global minimum of magnetic energy, we used the equilibrium an- gles to obtain magnetization and magnetoresistance curves. The results observed over the course of this study demonstrate the efficiency and versatility of the sputtering technique in the synthesis of ultrathin films and high-quality multilayers. This allows the deposition of magnetic nanostructures with well-defined magnetization and magnetoresistance parameters and possible technological applications

Funktionalisierte Latexpartikel

In der vorliegenden Arbeit wurden unter Verwendung neuer auf der Isophthalsäure basieren-der polymerisierbaren Tensiden carboxylfunktionalisierte Latexpartikel hergestellt, charakte-risiert und funktionalisiert. Im ersten Teil dieser Arbeit wurden 5-(10-Undecenyloxy)isophthalsäure (ISA-Vinyl), 5-(11-(4-Vinylphenoxy)undecyloxy)isophthal-säure (ISA-Sty), 5-(11-(2-Prop-1-enyl)phenoxy)undecyloxy)isophthalsäure (ISA-Pr), 5-(11-(1-Methacryloxy)undecylen)isophthalsäure (ISA-Met) und 5-(10-(3-Methylbut-3-enyl)oxy-1-oxydecylen)isophthalsäure (ISA-Bu) hergestellt. Die Surfmere wurden mit Styrol bzw. mit n-Butylacrylat copolymerisiert. ISA-Bu und ISA-Pr weisen während der Copolymerisation mit Styrol fast ideale Verläufe der Zeit/Umsatz-Kurven auf. Bei der Copolymerisation von ISA-Bu bzw. ISA-Vinyl mit n-Butylmethacrylat wurden ähnliche Ergebnisse erhalten. Die Carboxylgruppen an der Partikeloberfläche wurden mit Halogenderivaten verestert oder mit primären Aminen amidiert. Die funktionalisierten Partikel wurden mit der Polyelektrolyt-titration und konduktometrischen Titration, der IR- und UV-Spektroskopie, der Transmissi-onselektronenmikroskopie, der Fluoreszenzkorrelationsspektroskopie charakterisiert. Es konnte gezeigt werden, dass die Reaktanden kovalent an der Partikeloberfläche gebunden sind. Die Polymerpartikel wurden bei der Herstellung von Immunoassays genutzt. Die Adsorpti-onsisothermen zeigten, dass eine hohe Menge an Rinderserumalbumin an die Partikeloberflä-che physikalisch gebunden werden kann. In dieser Arbeit wurde ein einfaches Immunoassay hergestellt mit Biotin – Avidin als Modellsystem hergestellt. Die Surfmere wurden zur Stabilisierung von Miniemulsionen für die Miniemulsionspolymeri-sation genutzt. Im Laufe dieser Arbeit konnten mit dieser Methode Rylenfarbstoffe in Po-lystyrolpartikel stabilisiert werden.

TREAT-AND-EXTEND REGIMENS WITH ANTI-VEGF AGENTS IN RETINAL DISEASES: A Literature Review and Consensus Recommendations

PURPOSE A review of treat-and-extend regimens (TERs) with intravitreal anti-vascular endothelial growth factor agents in retinal diseases. METHODS There is a lack of consensus on the definition and optimal application of TER in clinical practice. This article describes the supporting evidence and subsequent development of a generic algorithm for TER dosing with anti-vascular endothelial growth factor agents, considering factors such as criteria for extension. RESULTS A TER algorithm was developed; TER is defined as an individualized proactive dosing regimen usually initiated by monthly injections until a maximal clinical response is observed (frequently determined by optical coherence tomography), followed by increasing intervals between injections (and evaluations) depending on disease activity. The TER regimen has emerged as an effective approach to tailoring the dosing regimen and for reducing treatment burden (visits and injections) compared with fixed monthly dosing or monthly visits with optical coherence tomography-guided regimens (as-needed or pro re nata). It is also considered a suitable approach in many retinal diseases managed with intravitreal anti-vascular endothelial growth factor therapy, given that all eyes differ in the need for repeat injections. CONCLUSION It is hoped that this practical review and TER algorithm will be of benefit to health care professionals interested in the management of retinal diseases.

Regression analysis of top of descent location for idle-thrust descents

In this paper, multiple regression analysis is used to model the top of descent (TOD) location of user-preferred descent trajectories computed by the flight management system (FMS) on over 1000 commercial flights into Melbourne, Australia. In addition to recording TOD, the cruise altitude, final altitude, cruise Mach, descent speed, wind, and engine type were also identified for use as the independent variables in the regression analysis. Both first-order and second-order models are considered, where cross-validation, hypothesis testing, and additional analysis are used to compare models. This identifies the models that should give the smallest errors if used to predict TOD location for new data in the future. A model that is linear in TOD altitude, final altitude, descent speed, and wind gives an estimated standard deviation of 3.9 nmi for TOD location given the trajectory parame- ters, which means about 80% of predictions would have error less than 5 nmi in absolute value. This accuracy is better than demonstrated by other ground automation predictions using kinetic models. Furthermore, this approach would enable online learning of the model. Additional data or further knowledge of algorithms is necessary to conclude definitively that no second-order terms are appropriate. Possible applications of the linear model are described, including enabling arriving aircraft to fly optimized descents computed by the FMS even in congested airspace.

On the leakage-power modeling for optimal server operation

Leakage power consumption is a com- ponent of the total power consumption in data cen- ters that is not traditionally considered in the set- point temperature of the room. However, the effect of this power component, increased with temperature, can determine the savings associated with the careful management of the cooling system, as well as the re- liability of the system. The work presented in this paper detects the need of addressing leakage power in order to achieve substantial savings in the energy consumption of servers. In particular, our work shows that, by a careful detection and management of two working regions (low and high impact of thermal- dependent leakage), energy consumption of the data- center can be optimized by a reduction of the cooling budget.
