The DREAM Framework: using a network of scalable ontologies for intelligent indexing and retrieval of visual content

There are still major challenges in the area of automatic indexing and retrieval of digital data. The main problem arises from the ever increasing mass of digital media and the lack of efficient methods for indexing and retrieval of such data based on the semantic content rather than keywords. To enable intelligent web interactions or even web filtering, we need to be capable of interpreting the information base in an intelligent manner. Research has been ongoing for a few years in the field of ontological engineering with the aim of using ontologies to add knowledge to information. In this paper we describe the architecture of a system designed to automatically and intelligently index huge repositories of special effects video clips, based on their semantic content, using a network of scalable ontologies to enable intelligent retrieval.

Semi-automatic knowledge extraction, representation and context-sensitive intelligent retrieval of video content using collateral context modelling with scalable ontological networks

Automatic indexing and retrieval of digital data poses major challenges. The main problem arises from the ever increasing mass of digital media and the lack of efficient methods for indexing and retrieval of such data based on the semantic content rather than keywords. To enable intelligent web interactions, or even web filtering, we need to be capable of interpreting the information base in an intelligent manner. For a number of years research has been ongoing in the field of ontological engineering with the aim of using ontologies to add such (meta) knowledge to information. In this paper, we describe the architecture of a system (Dynamic REtrieval Analysis and semantic metadata Management (DREAM)) designed to automatically and intelligently index huge repositories of special effects video clips, based on their semantic content, using a network of scalable ontologies to enable intelligent retrieval. The DREAM Demonstrator has been evaluated as deployed in the film post-production phase to support the process of storage, indexing and retrieval of large data sets of special effects video clips as an exemplar application domain. This paper provides its performance and usability results and highlights the scope for future enhancements of the DREAM architecture which has proven successful in its first and possibly most challenging proving ground, namely film production, where it is already in routine use within our test bed Partners' creative processes.

Digital imaging in popular cinema

This book investigates the challenges that the presence of digital imaging within the cinematic frame can pose for the task of interpretation. Applying close textual analysis to a series of case studies, the book demystifies the relationship of digital imaging to processes of watching and reading films, and develops a methodology for approaching the digital in popular cinema. In doing so, the study places contemporary digital imaging practice in relation to historical traditions of filmmaking and special effects practice, and proposes a fresh, flexible approach the the close reading of film that can take appropriate account of the presence of the digital.

Portals to the world: technological extensions to the boundaries of the home

This article examines the ways that technological objects inside the home are viewed and productively used by a group of older people to extend their access to environments beyond the home. Beginning with a discussion of types of domestic object, we highlight appliances and gadgets, and focus our attentions on the latter. The changes in life brought on by ageing, in particular a reduction in mobility, provide the context for our study, in which access to the outside world becomes increasingly difficult. Recognising their changing circumstances led our participants to actively and selectively engage with these objects, mitigating the shrinking of their accessible environment by using them as a gateway to the many virtual worlds now available. We coin the term ‘portal objects’ to describe the potential that this type of technological object provides, and suggest that the investigation of interiors can be enriched by recognising and including the worlds outside that become integral to occupation inside.

Unga vuxnas åsikter kring bokomslags formgivning : En enkät- och fokusgruppsundersökning

Bokomslaget är ofta läsarens första möte med en bok och det är därför viktigt att bokomslaget tilltalar och sänder ut rätt signaler till konsumenten. Målgruppen unga vuxna, individer mellan 16 och 27 år, är enligt bokbranschen en grupp som är svår att nå. Svårigheten kan ligga i att det finns en viss okunskap i vad unga vuxna tilltalas av på bokomslag. Det är även en bred målgrupp med många olika sorters individer. Målet med denna studie är att ge en bild av vad målgruppen unga vuxna tilltalas av i ett bokomslag. Vi ville ta reda på hur viktigt bokomslaget är för val av bok, samt hur målgruppen ser på omslagets specifika designfaktorer färg, typografi, illustration, fotografi och efterbehandling. För att ge oss en bild av dagens kunskapsläge har litteraturstudier och intervjuer med formgivare av bokomslag genomförts. Genom en omfattande enkätundersökning och utförda fokusgrupper fick vi fram målgruppens syn och tankar kring bokomslag. Fokusgrupper utfördes för att ge oss en djupare förståelse rörande hur målgruppen ser på bokomslag samt ge oss ett djupare resonemang kring de olika bokomslagen. Resultatet visar att unga vuxna lägger stor vikt vid identitet och ett bokomslag bör således sända tydliga signaler som kan bekräfta läsarens identitet. Typografin ska vara lättläst. Målgruppen ser helst fotografiska bilder på bokomslaget och omslaget ska förmedla en känsla av bokens innehåll. Färger i en dovare färgskala tilltalar unga vuxna, rött och svart tycks vara de populäraste färgerna överlag. Efterbehandlingen (t.ex. lackering och foliering) på ett bokomslag bör vara sparsam och användning av färgen rosa lika så.

Evaluating links through spectral decomposition

Spectral decomposition has rarely been used to investigate complex networks. In this work we apply this concept in order to define two kinds of link-directed attacks while quantifying their respective effects on the topology. Several other kinds of more traditional attacks are also adopted and compared. These attacks had substantially diverse effects, depending on each specific network (models and real-world structures). It is also shown that the spectrally based attacks have special effects in affecting the transitivity of the networks.

Thermodynamisches Verhalten von verzweigten im Vergleich zu linearen Polymeren

Diese Arbeit beschäftigt sich mit den Unterschieden zwischen linearen und verzweigten Oligomeren/Polymeren mit praktisch gleichem chemischem Bau. Untersucht wurden eine Reihe von ungeladenen Polymeren in Hinsicht auf deren Wechselwirkungsparameter mit Lö-sungsmitteln sowie peripher geladene Dendrimere im Hinblick auf deren Staudingerindices in Wasser. Bei den ungeladenen Oligomeren/Polymeren handelt es sich um Oligoisoprene, Polygly-cerine und Oligo-Dimetylsiloxane. Vor den thermodynamischen Messungen war es notwen-dig, die verzweigten Produkte durch diskontinuierliche Spinn-Fraktionierung von linearen Bestandteilen zu befreien. In diesem Zusammenhang wurden die Phasendiagramme der Aus-gangsproben und der fraktionierten Proben bestimmt und mit denen der entsprechenden linea-ren Polymeren verglichen. Die Ergebnisse zeigen deutliche Einflüsse der Molekularchitektur, wobei Mischungen aus linearen und verzweigten Polymeren plus niedermolekularen Flüssig-keiten infolge der Unverträglichkeit der hochmolekularen Komponenten ungewöhnliches Verhalten zeigen. Die Flory-Huggins Wechselwirkungsparameter von linearen und verzweigten Polyme-ren wurden mit Hilfe von Dampfdruckmessungen (Headspace-Gaschromatographie) und dampfdruckosmometrischen Messungen bei unterschiedlichen Temperaturen bestimmt. Es zeigt sich, daß die -Werte in komplexer Weise von der Konzentration abhängen und mit einem Ansatz nach Wolf (Gleichung 26 und 31) quantitativ modellierbar sind. Allgemein gilt die folgende Ungleichung: bra > lin. Die Untersuchungen bezüglich der Staudingerindeces von Polyelektrolyten wurden an vier Generationen von peripher geladenen Dendrimeren durchgeführt. Die Ergebnisse zeigen, dass die [ ] Werte mit zunehmender Generation deutlich sinken. Bei der 1. Generation ver-hält sich das Dendrimer noch sehr ähnlich wie lineare Polyelektrolyte. Mit steigender Zahl der Generationen nimmt der Staudingerindex trotz zunehmendem Molekulargewicht deutlich ab, da der Polyelektrolyteffekt (Aufweitung der Knäuel durch elektrostatische Wechselwirkung) an Bedeutung verliert. Der Grund dafür liegt in einer Zunahme des Abstands der Ladungen zur Hauptkette und der Tatsache, dass der Zahl der Ladungen pro Molekül bei konstantem n entsprechend einer quadratischen Reihe zu (2, 4, 8, 16) zunimmt. Wie aus Messungen an der ETH Zürich bekannt ist, verhalten sich ungeladene Dendrimere in organischen Lösungsmit-teln wie die Lösungen von linearem Polystyrol.

Biunal Lantern

A biunial magic lantern is a wooden box with two lenses, one on top of the other. The lenses have shutters and slots to insert glass slides. The light source is placed inside the box and the images are projected through either of the two lenses. It works in the same way as traditional magic lanterns, but allows for dissolving images and special effects.

Enhancing Authenticity in Simulation Using Appropriate Techniques of Moulage

Workshop Overview The use of special effects (moulage) is a way to augment the authenticity of a scenario in simulation. This workshop will introduce different techniques of moulage (oil based cream colors, watercolors, transfer tattoos and 3D Prosthetics). The participants will have the opportunity to explore these techniques by applying various moulages. They will compare the techniques and discuss their advantages and disadvantages. Moreover, strategies for standardization and quality assurance will be discussed. Workshop Rationale Moulage supports the sensory perception in an scenario (1). It can provide evaluation clues (2) and help learners (and SPs) to engage in the simulation. However, it is of crucial importance that the simulated physical pathologies are represented accurate and reliable. Accuracy is achieved by using the appropriate technique, which requires knowledge and practice . With information about different moulage techniques, we hope to increases the knowledge of moulage during the workshop. By applying moulages in various techniques we will practice together. As standardization is critical for simulation scenarios in assessment (3, 4) strategies for standardization of moulage will be introduced and discussed. Workshop Objectives During the workshop participants will: - gain knowledge about different techniques of moulages - practice moulages in various techniques - discuss the advantages and disadvantages of moulage techniques - describe strategies for standardization and quality assurance of moulage Planned Format 5 min Introduction 15 min Overview – Background & Theory (presentation) 15 min Application of moulage for ankle sprain in 4 different techniques (oil based cream color, water color, temporary tatoo, 3D prosthetic) in small groups 5 min Comparing the results by interactive viewing of prepared moulages 15 min Application of moulages for burn in different techniques in small groups 5 min Comparing results the results by interactive viewing of prepared moulages 5 min Sharing experiences with different techniques in small groups 20 min Discussion of the techniques including standardization and quality assurance strategies (plenary discussion) 5 min Summary / Take home points

La aplicación de stop-motion en arquitectura: materia y luz

Se inicia un análisis de los procesos de trabajo de stop-motion porque ayudan a comprender las diferentes escalas en arquitectura donde las maquetas se convierten en futuros prototipos de infraestructuras de edificios o de paisaje. Stop motion es una técnica de animación fotograma a fotograma de objetos estáticos mediante la manipulación de figuras de plastilina en entornos fijos con cambios de luz, color y sonido. Igual que dicha técnica reúne lo mejor del rodaje tradicional -story board, escenografía, fotografía, personajes, iluminación- la animación de maquetas de interiores sintetiza micro-procesos de mayor repercusión -habitaciones con cambios de humedad, de temperatura, de ventilación y de iluminación- incorporando efectos especiales que son procesados digitalmente en post-producción. Se construyen varios prototipos de habitación con parámetros fijos como el tamaño y la posición de la cámara y otros variables como los materiales, los personajes y la iluminación. Representan un mundo en miniatura que intenta aportar un acercamiento sensorial y atmosférico analizando la magia y la fantasía que Junichirô Tanizaki describe en la penumbra de las construcciones tradicionales japonesas y estudiando las imperfecciones de los escenarios que Tim Burton manipula en su películas de animación con una textura que las tecnologías digitales no pueden igualar. El objetivo es utilizar una escala micro para realizar unos modelos interiores donde las condiciones atmosféricas están controladas y reducidas, y tomar datos que se podrían aplicar a un proceso de modelado a escala intermedia para testar prototipos de edificios como el túnel de viento; o, finalmente, a una escala macro con maquetas de un sector de la costa o de un río donde los fenómenos meteorológicos son los protagonistas para simular inundaciones y diseñar futuras medidas de prevención y seguridad.

W.A. Mozart's Die Zauberflöte An Arrangement and Performance Edition for Wind Instruments and Vocal Soloists

The purpose of this dissertation is to produce a new Harmonie arrangement of Mozart’s Die Zauberflöte suitable for modern performance, bringing Joseph Heidenreich’s 1782 arrangement—one of the great treasures of the wind repertoire—to life for future performers and audiences. I took advantage of the capabilities of modern wind instruments and performance techniques, and employed other instruments normally found in the modern wind ensemble to create a work in the tradition of Heidenreich’s that restored as much of Mozart’s original thinking as possible. I expanded the Harmonie band to include flute and string bass. Other instruments provide special effects, a traditional role for wind instruments in the Classical opera orchestra. This arrangement is conceived to be performed with the original vocal soloists, making it a viable option for concert performance or for smaller staged productions. It is also intended to allow the wind players to be onstage with the singers, becoming part of the dramatic action while simultaneously serving as the “opera orchestra.” This allows creative staging possibilities, and offers the wind players an opportunity to explore new aspects of performing. My arrangement also restores Mozart’s music to its original keys and retains much of his original wind scoring. This arrangement expands the possibilities for collaboration between opera studios, voice departments or community opera companies and wind ensembles. A suite for winds without voices (currently in production) will allow conductors to program this major work from the Classical era without dedicating a concert program to the complete opera. Excerpted arias and duets from this arrangement provide vocalists the option of using chamber wind accompaniment on recitals. The door is now open to arrangements of other operas by composers such as Mozart, Rossini and Weber, adding new repertoire for chamber winds and bringing great music to life in a new way.

O cinema de Ray Harryhausen: efeitos especiais e maneirismo no cinema de Hollywood

Através de uma análise histórico-formal, este trabalho propõe uma leitura maneirista da obra de Ray Harryhausen (1920-2013), um dos maiores criadores de efeitos especiais do cinema de Hollywood, verdadeiro autor de uma série de filmes que se distinguem pelo uso virtuoso da técnica, colocada ao serviço de narrativas fantásticas, construídas numa clara referencia a grandes clássicos do cinema de Hollywood.

A brief report on a survey of the fish and fisheries of the Tana river, with special reference to the probable effects of the proposed barrages

The construction of several barrages in order to develop the hydroelectric and irrigation potential of the Tana river has been proposed and the probable effects of these developments upon the fish and fisheries of the area' has been investigated. Briefly in the highest reaches the sport fishery will be unaffected, in the middle reaches the sparse subsistence fisheries will be only slightly inconvenienced but in the terminal reaches of the river the subsistence and commercial fishing enterprises are expected to be seriously reduced by the progressive re-regulation of river-flow. However each new dam will support a new and productive reservoir fishery and with proper development the annual yield of fish from the Tana basin is expected to increase considerably.

Effects of body size and water temperature on food consumption and growth in the sea cucumber Apostichopus japonicus (Selenka) with special reference to aestivation

To investigate the effects of body size and water temperature on feeding and growth in the sea cucumber Apostichopus japonicus (Selenka), the maximum rate of food consumption in terms of energy (C-maxe; J day(-1)) and the specific growth rate in terms of energy (SGRe; % day(-1)) in animals of three body sizes (mean +/- SE) - large (134.0 +/- 3.5 g), medium (73.6 +/- 2.2 g) and small (36.5 +/- 1.2 g) - were determined at water temperatures of 10, 15, 20, 25 and 30 degrees C. Maximum rate of food consumption in terms of energy increased and SGRe decreased with increasing body weight at 10, 15 and 20 degrees C. This trend, however, was not apparent at 25 and 30 degrees C, which could be influenced by aestivation. High water temperatures (above 20 degrees C) were disadvantageous to feeding and growth of this animal; SGRe of A. japonicus during aestivation was negative. The optimum temperatures for food consumption and for growth were similar and were between 14 and 15 degrees C, and body size seemed to have a slight effect on the optimal temperature for food consumption or growth. Because aestivation of A. japonicus was temperature dependent, the present paper also documented the threshold temperatures to aestivation as indicated by feeding cessation. Deduced from daily food consumption of individuals, the threshold temperature to aestivation for large and medium animals (73.3-139.3 g) was 24.5-25.5 degrees C, while that for small animals (28.9-40.7 g) was between 25.5 and 30.5 degrees C. These values are higher than previous reports; differences in sign of aestivation, experimental condition and dwelling district of test animals could be the reasons.
