Världen som vi ser den : En undersökning om hur vi läser trovärdighet i andefotografier
Denna undersökning handlar om olika sätt att titta på och uppfatta fotografier. Frågeställningen tar upp hur vi läser av trovärdighet i ett fotografi. Undersökningen tar upp olika synsätt och faktorer som kan påverka fotografiers trovärdighets som till exempel hur fotografiets teknik och dess koppling till det avbildade påverkar hur vi ser på fotografier. Eller till exempel hur möjligheten att bearbeta fotografier påverkar trovärdigheten. Temat i undersökningen är fotografier på spöken och andar.
Automobike: en cykel med aktiv balans
During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.
Nivåmätning av ojämna ytor
Examensarbetet undersöker om det är möjligt att utföra en nivåmätning där underlaget är ojämnt med en begränsad budget och ändå få ett tillförlitligt resultat.För att kunna testa det så används tre stycken ultraljud sensorer i ett skåp som simulerar en container. Varje sensor utför mätningen och sedan filtreras värdena. Hela systemet filtreras sedan med ytterligare ett filter och då blir noggrannheten ca 4 cm från den riktiga fyllnaden. Miljöpåverkan skulle bli mindre om det framtagna systemet installerades i alla containrar vid de miljöstationer som finns i Sverige. Lastbilarna som ska tömma innehållet behöver aldrig köra till en ha lvtom container vilket även drar ner kostnaderna för miljöstationerna.
Turismutveckling i ett världsarvsområde : Lokal delaktighet
This is a qualitative case study of young womens? experiences of blogging about One Direction on the social media/microblogging platform Tumblr. The aim of this study was to find out what fan blogging is and why fans blog. We did this by creating an account on Tumblr where we invited young women between the ages of 16?29, who had active fan blogs dedicated to One Direction, to answer an open-ended questionnaire.

Layoutgenerator för en multiplikator i "overturned stairs" trädstruktur
Multiplikatorer används ofta som ett byggblock vid konstruktion av kretsar som digitala filter, FFT-processorer och aritmetiska enheter. Olika trädstrukturer används i"höghastighet"applikationer för multiplikatorer. En typ av träd,"overturned-stairs"(OS) som är ett adderarträd av första ordningen har uppvisat lika optimal prestanda med avseende på hastighet som Wallace-träd, vid 18 eller färre ingångar. I moderna integrerade kretsar, ger ledningar och kopplingar upphov till fördröjningar och parasitiska laster. I en jämförelse mellan Wallace-träd, och OS1-träd har det sistnämda kortare och mindre komplicerad ledningsdragningar och är därför mer ändamålsenlig för VLSI implementationer..

Användning av accelerometrar för detektering av rörelse i Husqvarna ABs gräsklippare Automower
In order to detect movements and vibrations on different appliance, especially robots and self-going devices are used different sensors. One of the most used movement sensors are accelerometers. They are three different types of accelerometers one-axes, two-axes and three-axes. They can be analogue or digital. Husqvarna AB uses an accelerometer to detect movements of their self-going lawnmower Automower.

Visualisering och beräkning av hudkapillärer
The aim of this thesis was to develop an objective and automatic method for identifying capillaries in microscope images of the skin. Furthermore, statistical data about the identified capillaries and the capillary distribution should be computed and stored in a database. The method was implemented using the platform independent programming language Java. An analysis of microscope improvement using various polarization filter setups and wavelength filtershas also been performed, as well as a pilot study of the effect of applying a local anaesthetic cream on the skin. The method is developed and aimed at research on various pathological skin conditions affecting the capillary distribution.
Utvärdering och konstruktion av SVIA:s standardmaskin FeedLine
This report describes an bachelor thesis work which is performed in cooperation with SVIA that develops and sells automation solutions for the manufacturing industry. The thesis purpose was to evaluate the machine FeedLine to find opportunities for improvement in the product?s design that could lead to more standardization and thus improving the efficiency of manufacturing and assembly.Based on these basic issues suggestions for improvements were developed:How can the design of FeedLine be improved to facilitate the assembly?Can more standardization be imposed on FeedLine?s design to enable more stocking of standard components?An initial pre-study was conducted to evaluate FeedLine?s to find opportunities for improvement in its overall design. During the pre-study staff at SVIA and two of its clients was interviewed. Based on information gathered during the interviews and observations by the authors improvements was amendments.
