When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.

This study aims to analyze the risks with building new households between railroads and shore, the focus of the study lays on Öbacka strand in Umeå municipality. The study also investigate if a land use conflict has taken place and how it was handled.The paper is based on different documents that was central for the work of planning the households and some interviews with operators that was highly involved with the planning of the area.The results shows that there is several risks with establishing new household between railroads and shores. Mainly because of the exposure of noise from the railways, though the risk for impact on the living environment for animals were low in this case there is a generally risk that it could get negative effects. It also a very important that the availability to the shore is secured. Planning in this type of area involves a great number of operators can easily cause a conflict due to the different perspectives on how the land should be used in the future, and also because of protecting different interests.

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

The chief aim of this study is to investigate the impact of context on written peer response. A second aim is to explore students? attitudes towards peer response. The investigation has taken place at an upper secondary school in the south-east of Sweden, involving 20 students in grade 2 and 3 in the course Swedish C. The investigation is based on the students? comments on their peers? speech drafts and six qualitative interviews.

The aim of this examination paper is to investigate the use of linguistic feedback among male senior high school students. Two groups consisting of male students preparing for ensuing studies, and two groups consisting of male students taking vocational studies, was interviewed in four separate interviews. By comparing how these four groups used linguistic feedback in conversation noticeable differences has been identified. For example, the boys preparing for ensuing studies used linguistic feedback the most. Also, all interviewed groups used linguistic feedback the most when they agreed with each other.

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Uppsatsen Röst och inskription. Utkast till den inre monologens teckenteori kan sammanfattas som ett försök att beskriva och förklara strukturella och funktionella egenskaper hos inre monolog (i engelsk litteratur inner speech), samt relatera dessa egenskaper till ?yttre?, dialogiskt talspråk. En axial grundtanke som löper genom hela undersökningen är att monologen inte utan vidare låter sig reduceras till en enkel formel som ?talspråk minus röst? etc., utan att monologen bör anses betingad av andra lingvistiska förutsättningar, bland vilka frånvaron av fysisk röstbildning bara är en bland flera faktorer..

The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.

Velofarynxinsufficiens (VFI) inneba?r en nedsatt fo?rma?ga att under tal och fo?dointag sta?nga till mellan mun- och na?sha?la vilket leder till ett avvikande tal. Operation med svalglamba? a?r en metod som kan anva?ndas fo?r att behandla VFI och tidigare forskning har visat goda resultat avseende dess effekt pa? talet. Dock menar vissa forskare att operationen kan ha negativa effekter och att den bakomliggande orsaken till insufficiensen kan pa?verka graden av framga?ng.

Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.

Speech Transmission Index (STI) är både en metod för att mäta taltydlighet och en skala som beskriver taltydlighet. Metoden presenterades av H. Steeneken och T. Houtgast 1985 och har därefter fått många användningsområden. STI beräknas utifrån modulationsindex, där modulationsindex är förändringen av modulation genom ett system.

The aim of this essay is to answer the question of how ? in what ways ? Jeanette Wintersons Written on the Body and Sarah Waters? Tipping the Velvet are queer texts. My method is that of a thematic analysis, focusing on words and phenomenon related to definitions of the multi facetted term ?queer?. The analysis covers themes of lesbian focus, performativity, performance, speech-acts, and heteronormative and queer relationships.

Skuggor i 3D-miljöer är ett mycket efterforskat område, och detta arbete koncentrerar sig på shadow map-algoritmen. Det finns ett problem med denna algoritm, för då en shadow map projiceras på en yta som är större än sig själv så bildas stora trappstegseffekter, vilket kallas aliasing. Problemet som har undersökts är hur olika shadow map-algoritmer i en miljö med långa skuggor beter sig, där ett minimerat antal artefakter så som brus och aliasing är synligt. För detta undersöktes Percentage-Closer Filtering (PCF), som är en variant av shadow map, med olika samplingstekniker ? och även en vidarebyggnad med Percentage-Closer Soft Shadow (PCSS) implementerades.

Since some years Linköping has invested in biogas production, mainly from offal's, residuals from food industry and manure. The municipality goes for biogas in the local traffic and in all transportation. It is also possible for private car owners to run their cars on biogas. The purpose of this essay is to perform a cost-benefit analysis and examine if the project has been beneficial from a social point of view. The effects have been identified, measured and monetarily valued. The essay is limited to include the year of 2006 only.
