Este trabalho apresenta o estudo e implementação de um sistema para vinculação e visualização de imagens de ressonância magnética nuclear e tomografia computadorizada a partir de um sistema de informação em radiologia (RIS), possibilitando a recuperação e disponibilização dos exames (laudos e imagens), através de rede \"ethernet\", para visualização a partir de uma interface desenvolvida para \"browser\". Os exames podem ser recuperados através do número de registro (RGHC) ou do nome do paciente. As imagens utilizadas no trabalho estão nos padrões DICOM 3.0 (Digital Imaging and Communications in Medicine) e JPEG (Joint Photographic Experts Group). Para a vinculação dos exames que possuem suas imagens em JPEG foi desenvolvida uma interface para inclusão das informações necessárias que garantem a consistência deste processo. Para os exames que possuem suas imagens em formato DICOM 3.0 as informações foram extraídas automaticamente dos cabeçalhos e armazenadas no banco de dados. O sistema possui uma interface amigável ao usuário, podendo ser rapidamente incorporada ao projeto de um PACS (Picture Archiving and Communication System). A implementação foi idealizada para servir ao Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP/USP), com base no seu sistema de informação em radiologia. Os resultados demonstram que o tempo de retorno das imagens é clinicamente satisfatório e considerado bom pela avaliação qualitativa dos médicos. / This work presents the study and implementation of a system aiming the indexing and visualization of the images of nuclear magnetic resonance and computerized tomography from a radiology information system (RIS), allowing the retrieval and availability of the exams (results and images), through an ethernet net for visualization beginning with an interface developed to a browser. The exams may be recovered either through their register number (RGHC) or the patient\'s name. The images employed in the work follow the DICOM 3.0 (Digital Imaging and Communications in Medicine) and JPEG (Joint Photographic Experts Group) patterns. For the indexing of the exams that present images in JPEG, an interface was developed to include the information required to guarantee the consistency of the process. For the exams presenting the DICOM 3.0 format, information was extracted automatically from the heading and filed in the database. The system has a friendly interface for the user, it may be rapidly incorporated to the project of an PACS (Picture Archiving and Communication System). The implementation was idealized to serve the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto, of the Universidade de São Paulo (HCFMRP/USP), based on its radiology information system (RIS). The results demonstrated that the time of retrieval of the images is satisfactory and considered good by evaluation qualified of the doctors.

The spatiality of a viewer. A comparative exhibition analysis of Hilma af Klint's work The ten largestthrough two different spatialities.I have studied a viewer’s encounter with Hilma af Klint’s work The ten largest through two differentspatialities, the exhibition room at Moderna Museet Malmö and Moderna Museet Malmös Instagramaccount. With my research, I have wanted to get an insight into how a digital room such as an Instagramaccount can function as an exhibition room for art in a time when more and more is digitalized, whichescalated during the year when physical experiences were limited due to a global pandemic. Through acomparative exhibition analysis of the two different spaces and with the help of phenomenological theoryprimarily based on Maurice Merleau-Ponty further developed by Bia Mankell and phenomenologicaltheory in the digital based on Emmanuel Alloa, the Instagram account has been set in relation to theexhibition room at the museum. This comparative analysis showed that the two spatialities as exhibitionroom for the same work is both two separated exhibitions with characteristics influenced by space theyare shown through but also as two inevitably intertwined exhibitions and spaces influenced by each otherand each other's characteristics. / Populärvetenskaplig sammanfattningI den här uppsatsen har jag undersökt en betraktares möte med Hilma af Klints verk De tio största genomtvå olika rumsligheter, visningsrummet på Moderna Museet Malmö samt Moderna Museet Malmösinstagramkonto. Jag har med min undersökning velat få en inblick i hur ett digitalt rum så som ettinstagramkonto kan fungera så ett visningsrum för konst i en tid då mer och mer digitaliseras, vilket underåret eskalerat då fysiska upplevelser begränsats på grund av en global pandemi. Genom en komparativutställningsanalys av de två olika rumsligheterna och med hjälp av fenomenologisk teori framföralltutifrån Maurice Merleau-Ponty vidareutvecklad av Bia Mankell och fenomenologisk teori i det digitalautifrån Emmanuel Alloa har instagramkontot satts i relation till visningsrummet på museet. Dennakomparativa analys ledde fram till en syn på de två rumsligheterna för samma verk både som två separatautställningar med egenskaper påverkade av det rum de visas genom men även som två oundvikligensammanflätade utställningar och rum påverkade av varandra och varandras egenskaper.

The purpose of this master’s thesis is to simplify the exchange (in both directions) of multimedia content between mobile phones and network attached web servers. The solution proposed in this report specifically concerns displaying Multimedia Messaging Service (MMS) messages via a web browser connected to a network-attached web server and graphically authoring MMS messages via a web interface. This thesis project is important because it brings multimedia content, in the form of MMS messages, from isolation in the telecommunication world closer to wide availability via the Internet. This transition is very important as the Internet is where media is shared with the world today. This approach brings added value to end users who want to share content generated using their phone on a web site. It also provides added value to operators who want to increase the amount of MMS traffic in their networks. The solution is non-trivial because there are a number of complexities at both ends. This is because the MMS messages that are authored at mobile phones differ between both handset models and manufacturers. Moreover, the format used for MMS (MMS SMIL) is not widely used on the Internet, thus a transformation to an Internet browser supported format must be performed. The thesis examines to what extent this transformation can be completely automatic and how MMS messages can be authored through a web interface. The results show that MMS messages can be successfully transformed to HTML and embedded directly in web pages, thus providing a seamless experience for viewing MMS messages. Depending on the content of the MMS message in question, the current browser and which media player plug-ins are available, the generated HTML will be displayed differently. The results also show that MMS messages can be composed in real time* through a web interface with good results. / Syftet med detta examensarbete är att förenkla utbyte (i båda riktningarna) av multimedia mellan mobiltelefoner och nätverksuppkopplade webbservrar. Lösningen som föreslås i denna rapport behandlar specifikt hur Multimedia Messaging Service (MMS)-meddelanden kan visas i en webbläsare via nätverksuppkopplade webbservrar och hur MMS-meddelanden kan komponeras grafiskt via ett webbinterface. Detta examensarbete är viktigt eftersom det för multimedia, i form av MMS-meddelanden, från isolering i telekommunikationsvärlden närmare en bred tillgänglighet via Internet. Denna övergång är viktig eftersom det är på Internet som multimedia görs tillgängligt för världen i dagens läge. Denna approach förbättrar upplevelsen för användare som vill dela med sig av innehåll genom sin telefon genom en hemsida. Den ökar också möjligheterna för mobiloperatörer att öka MMS-trafiken i sina nätverk. Lösningen är inte trivial eftersom det existerar ett antal komplexiteter i båda ändarna. Detta beror på att MMS-meddelanden som skapas i mobiltelefoner skiljer sig åt mellan såväl tillverkare som modeller. Dessutom används inte MMS-formatet (MMS SMIL) på Internet. Således måste en transformering till ett format som stöds av webbläsare genomföras. Detta examensarbete undersöker i vilken utsträckning denna transformering kan automatiseras helt och även hur MMS-meddelanden kan skapas via ett webbinterface. Resultaten visar att MMS-meddelanden framgångsrikt kan transformeras till HTML och bäddas in på en hemsida på ett sådant sätt att de upplevs som en del av hemsidan. Beroende på vilken typ av media som MMS-meddelandet innehåller, den aktuella webbläsarkonfigurationen och på vilka mediaspelar-plug-ins som finns tillgängliga, måste olika HTML genereras för att innehållet ska visas på ett bra sätt. Resultaten visar också att MMS-meddelanden kan skapas grafiskt, i realtid, direkt genom ett webbinterface med goda resultat.

The history of photography represents a constant technological development of the medium towards increasing sophistication, which is related to spreading possibilities of complex control upon semantic meaning of each camera image. The thesis comparatively analyses expressive possibilities of film and digital photography with emphasis on the relations of both medium with other audiovisual means of communication. The thesis compares technological possibilities of both medium and focuses on growing integration of digital methods of imaging with new media through computer graphics. The thesis focuses on transforming role of photography in the society which is connected with democratization of access to cameras and the possibility of sharing resulting images via internet and social media. Based on described data the author points out the changing role of the creator and the viewer in the process of interpretation of visual images.

Frame rate is a fundamental element of creating the illusion of movement in video based media. For almost a century film has been produced in agreement with a standard frame rate of 24 frames per second, originally established due to technical limitations. This number lives on for films today, despite many technological innovations and other video based media formats straying from this standard. With contemporary video technology, content cannot only be recorded in higher frame rate; frames can also be artificially interpolated. So called Frame Interpolation technology now comes as a pre-installed feature on most televisions. As a consequence, this has formed a debate on how video based media should be presented, not least when it is artificially generated outside of the creators’ control. This study therefore aims to explore how manipulation of a video clip’s frame rate influences the viewer experience and thereby if the use of Frame Interpolation technology in televisions is justified. A study was conducted wherein participants were shown video clips in their original frame rate and compared them to artificially manipulated copies. The results showed that there is no definitive frame rate that is preferred by all participants and that some participants did not perceive any difference at all. It is also shown that the artificial manipulation of frame rate is generally not appreciated, and that criticisms against its use are misguided in terms of content shown. It is then discussed how television manufacturers should reconsider the use of Frame Interpolation technology. Lastly, we affirm how the results of this study are limited in accuracy by its scope. Further exploration of the subject is suggested to further consider these results found here and the results of earlier papers. / Bildhastigheten i videobaserad media är en fundamental aspekt i hur vi översätter stillbild till rörlig bild. Sedan ett sekel tillbaka produceras film enligt en standard bildhastighet på 24 bilder per sekund, på grund av tekniska begränsningar. Den siffran lever kvar än idag, trots tekniska innovationer samt andra videobaserade medier som töjt på denna standard. Med modern teknik kan media inte bara spelas in i högre bildhastigheter; bilder kan också artificiellt interpoleras. Frame Interpolation-teknik som den kallas kommer numera förinställd på de flesta tv-apparater. Som konsekvens har det förts debatt för och emot högre bildhastigheter, inte minst när de manipuleras av tv-tillverkare utöver skaparnas kontroll. Den här studien vill ta reda på hur manipulering av ett videoklipps bildhastighet påverkar människors känslomässiga tittarupplevelse och därigenom om bruk av Frame Interpolation-teknik i tv-apparater är motiverad. Undersökningen testade deltagarna genom att visa klipp i sin ursprungliga bildhastighet i jämförelse med artificiellt manipulerade kopior. Studien visade att det inte binärt går att bestämma en bildhastighet som deltagarna fann definitivt bäst och att skillnaden inte är uppenbar för alla. Resultatet visar också att artificiell manipulering av bildhastighet inte uppskattas, och att kritiken riktar sig mot fel innehåll. Det diskuteras därför om tv-tillverkare bör överväga användningen av Frame Interpolation-teknik. Slutligen klargörs det varför man ska ställa sig kritisk inför resultaten utifrån studiens begränsningar. Vidare forskning föreslås som kan stödja studiens och liknande studiers slutsatser.

<p>When an observer detects changes in a scene from a viewpoint that is different from the learned viewpoint, viewpoint change caused by observer’s locomotion would lead to better recognition performance compared to a situation where the viewpoint change is caused by equivalent movement of the scene. While such benefit of observer locomotion could be caused by spatial updating through body-based information (Simons and Wang 1998), or knowledge of change of reference direction gained through locomotion (Mou et al, 2009). The effect of such reference direction information have been demonstrated through the effect of a visual cue (e.g., a chopstick) presented during the testing phase indicating the original learning viewpoint (Mou et al, 2009).</p> <p>In the current study, we re-examined the mechanisms of such benefit of observer locomotion. Six experiments were performed using a similar change detection paradigm. Experiment 1 & 2 adopted the design as that in Mou et al. (2009). The results were inconsistent with the results from Mou et al (2009) in that even with the visual indicator, the performance (accuracy and response time) in the table rotation condition was still significantly worse than that in the observer locomotion condition. In Experiments 3-5, we compared performance in the normal walking condition with conditions where the body-based information may not be reliable (disorientation or walking over a long path). The results again showed a lack of benefit with the visual indicator. Experiment 6 introduced a more salient and intrinsic reference direction: coherent object orientations. Unlike the previous experiments, performance in the scene rotation condition was similar to that in the observer locomotion condition.</p> <p>Overall we showed that the body-based information in observer locomotion may be the most prominent information. The knowledge of the reference direction could be useful but might only be effective in limited scenarios such as a scene with a dominant orientation.</p> / Master of Science (MSc)

Sociological Research of TV Audience Behaviour Factors Determining The Time Spent Watching TV ABSTRACT The thesis deals with the phenomenon of TV viewing and with TV audience behaviour research. The theoretical part demarcates watching TV within leisure activities and deals with the question of motivation for watching TV as well. It also mentions the approach of people who intentionally try to exclude TV from their life. The text does not omit even the important contemporary determinants of watching TV - Internet and digitization of TV broadcasting. Subsequently, the main methods of TV audience behaviour research in the Czech Republic are introduced. In the empirical part, the main factors that most affect the time spent watching TV are being identified - first through separate elementary analyses and afterwards through searching for a regression model that would best predict the time spent watching TV for individuals and groups based on their socio-demographic and other characteristics. Keywords: television, time spent watching TV, watching TV, ATS, Peoplemeter, TVmeter, TV viewer, TV audience behaviour research
