The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

Syncore Technologies har tagit fram en digital telemetri mottagare som använder sig av USBperiferi anordning som ska kunna etablera oavbruten kommunikation mot sin värddator.Den tidigare designen av USB applikationen till digitala mottagaren är utvecklat av ett annatföretag. Problemet med den designen är att den kan stanna av under överföringen. Ett krav förden nya designen av USB gränssnittet är att den ska kunna etablera ett konstant data flödeutan att under en längre tid stanna av mitt under överföringen. Syftet med detta arbete är attordna en stabil överföring mellan mottagare och dator. Gruppen har valt att användanuvarande kretsuppsättning och utveckla egen mjukvara.

We have investigated the visual representation of men and women in Aftonbladet?s weight site. We have made a calculation of how many of the women and the men who were portrayed smiling/ not smiling, active/passive, looking into the camera/looking away from the camera and from which camera angle the picture is taken. We also kept statistic on the gender representation of the authors of the articles.Our investigation shows that Aftonbladet?s weight site has a distinct overrepresentation of women on their pictures, but also in terms of the authors of the articles.

Detta examensarbete är utfört i samarbete med System Andersson AB. Uppgiften var att undersöka huruvida det nuvarande verkstadssystemet, som i dagsläget är en Windowsapplikationen, skulle fungera som en webbapplikation. Webbapplikationen skulle bestå av ett antal begränsade funktioner som var instämpling/utstämpling, fungera som helskärm utan ramar från webbläsare, skapa rapporter samt fungera med pekskärm.Resultatet blev en väl fungerande webbapplikation där alla funktioner fungerar med undantag för skapandet av rapporter vilket inte stödes av utvecklingsverktyget.Rapporten ger den teoretiska bakgrunden och beskriver utvecklingen av webbapplikationen med bl.a. val av olika utvecklingsverktyg. Rapporten beskriver också hur webbapplikationen testats..

Construction production always contains different disciplines whose priorities andinterests can be very diverse. Good communication and coordination are essential tominimize misunderstandings and achieve good quality in the end result. This makesplanning a central part of the production management. In a world where conditionscan change as often as daily, being well prepared increases the opportunities to stayflexible and decrease negative effects of the changes.This study has been done in association with Skanska Foundations district North inStockholm in order to investigate how visual planning can be used in the productionmanagement to optimize the coordination and the quality.The history of Lean started at Toyota, but the concept are now spread over theworld and are used wide outside of the car industry nowadays. What?s challengingabout Lean in foundation projects is to embrace a long-term perspective and invest insolutions that are profitable in the longer term, instead of solve problems by onlytreating the symptoms.A holistic perspective is crucial in order to truly understand Lean.

Image indexing research today is either conducted on a visual attribute level or on a higher semantic level, forming a semantic gap between the two. There is much to gain if research progress from the two fields is combined. Image retrieval using access points in both visual and semantic significations could improve retrieval and bridge the gap. In social media today, images are often the primary communication agent and the number of images on the web is increasing in an uncontrolled way. New and efficient ways to index and retrieve the images are needed.The purpose of this study is to examine if emotions could be a semantic access point for image retrieval and if folksonomy indexing is useful when searching for images that represent emotions.

Jag har i det här arbetet gjort en analys av skillnaden mellan analog och digital summering avljudspår. Analyserna gjordes med avseende på frekvensspektrum, transientrespons och fasdifferens.Det gjordes genom att jag skrev och spelade in två låtar att använda till analyserna, mixade dessaoch körde ut till 24 separata ljudspår per låt. De summerades sedan på tre olika mixerbord och i treolika mjukvaror, för att sedan med Adobe Audition analysera hur frekvensspektrum,transientrespons och fasdifferens ändrats. Därefter gjordes genomsnitt för de analoga och de digitalasummeringarna för att se om det fanns några skillnader dem emellan. Även om det fanns gott omskillnader mellan mixerborden så var fasdifferenser det enda som var genomgående för alla analogasummeringar mot de digitala..

The purpose of the project was to make a system that could extract data from a mobile eye tracker and make it comparable with data from visual stimuli. The produced system was programmed in Java and provided all the necessary parts that were required to achieve the purpose. This provides a foundation for further research to determine whether the eye tracker is sufficiently accurate to diagnose Parkinson?s disease..

Previsualisation är en arbetsprocess som i ett tidigt stadie ger oss preliminära versioner av bilder eller sekvenser. Den är till för att kunna uppskatta produktionskraven, visualisera ideér och en gemensam vision. En teknisk previsualisation är en mer specifik term där teknisk exakthet är avgörande. En teknisk previs kan skapas i programmet FrameForge Pré-viz Studio som denna text redogör för. Previsualisationen som beskrivs i denna text lägger grund för diskussioner kring hur den kan användas på en filminspelning.

The purpose of this study is to achieve an understanding of how a CE- marking process is conducted and to identify the relevant factors that must be considered in such a process. We have conducted our study at Lo?vhults Svets & Smide AB (Lo?vhults) in Skruv, Sma?land Sweden, which are manufacturing brackets for small covering constructions.To understand how a CE-marking process is conducted several documents and provisions have been reviewed to achieve a basic understanding and insight of the subject. It thus led to that guideline ETAG 015 were studied and the factors to be considered in the CE-marking of brackets were identified. Together with Jan-A?ke Johansson at Lo?vhults we agreed on four different brackets to investigate for a potential CE-marking.

In a time where information overload is a fact, well formulated messages is required and communication is a big contributing element for building strong brands. In the north of Sweden, Norrmejerier is one of the big actors with dominance on the dairy factor market. Through making milk products that lands in the consumers refridgerators, they are not only working for economical interest but also for improving the nature of the north of Sweden. Through visual communication, Norrmejerier shows the consumers a beneficial view of the north of Sweden which corresponds to the populations own impression of their part of the country. This contributes to a feeling of belonging that makes strong and loyal consuments. The feeling of belonging is also reflected in Norrmejeriers commercial movies, that uses the consumers conscience to make costumers. By two group interviews and a semiotic analysis of Norrmejeriers commercial movies, this study aims to examine how Norrmejerier uses qualities of the north of Sweden when building their brand.

Subject of this study is the evolvement of the radical art music scene in Sweden. In this development took the labour movement an active part during the 1960s. The purpose of this study is to examine how the relationship between the radical art music scene and the labour movement was constituted and what this relationship implied for the Swedish radical art music scene during the 1960s.During the 1960s radical music became an influencial part in the Swedish music scene of modern art music. In this development the artists? society Fylkingen had a central position.

Purpose: Exploring the relatively new technology of convolution reverb, to gather knowledge on its limitations when used practically in the production of pop music, and from these findings to learn about applications in other performing arts and sound design. Methodology: This is a case study of creating convolution reverb by doing impulse responses (IR) and then applying them to studio recorded pop music. The empirical data consists of the final song results, notes and journals from during the process and the comparisons, as well as established litterature on acoustics, psycho-acoustics and music production. Results: Convolution reverb can widely and freely be used in the production of music and other audio-based art forms, since our study shows that the result of a well-made impulse response from a particular room is indistinguishable from music that is actually played and recorded in the same space..

The object with this work was to create a simple feeding program for beef cows. Another object was that I could learn more about the properties and functions of Excel and Visual Basic. I used parts of a program I designed a few years ago. This old program was neither user friendly nor had it an appealing layout. Initially I decided how I wanted the new program to appear and on which foundation it should be built. I designed various forms into a spread sheet, such as lists and multiple choice buttons. Using VBA (Visual Basic for Application) I could create macros, which used the information chosen in the lists and with the multiple choices to calculate the feeding requirement or the feeding plan.

Syftet med denna uppsats är att identifiera och beskriva resonanser mellan 20 Hz och 200 Hz, såväl teoretiskt som genom mätningar, i studion vid avdelningen för Ljud & Vibrationer vid Luleå Tekniska Universitet. Den variabla Helmholtzabsorbenten Varitune V-4 undersöktes med avseende på dess öppningsstorlek i förhållande till resonansfrekvens inne i resonatorns volym. Studion är utrustad med nio stycken variabla Varitune V-4 absorbenter för låga frekvenser. Detta gjordes i syfte att föreslå den kombination av öppningsstorlekar vilken resulterar i störst dämpning av problemresonanser rummet. Resultaten visar på svårigheter att bevisa effekten av den lågfrekventa dämpningen i rummet, utom för resonans mellan tak och golv..
