Modern semiconductor design methods makes it possible to design increasingly complex system-on-a-chips (SOCs). Testing such SOCs becomes highly expensive due to the rapidly increasing test data volumes with longer test times as a result. Several approaches exist to compress the test stimuli and where hardware is added for decompression. This master?s thesis presents a test data compression method based on a modified facsimile code.

Denna rapport tar en titt på phishing-problemet, något som många har råkat ut för med bland annat de falska Nordea eller eBay mejl som på senaste tiden har dykt upp i våra inkorgar, och ett eventuellt sätt att minska phishingens effekt. Fokus i rapporten ligger på klassificering av mejl och den huvudsakliga frågeställningen är: ?Är det, med hög träffsäkerhet, möjligt att med hjälp av ett klassificeringsverktyg sortera ut mejl som har med phishing att göra från övrig skräppost.? Det visade sig svårare än väntat att hitta phishing mejl att använda i klassificeringen. I de klassificeringar som genomfördes visade det sig att både metoden Naive Bayes och med Support Vector Machine kan hitta upp till 100 % av phishing mejlen. Rapporten pressenterar arbetsgången, teori om phishing och resultaten efter genomförda klassificeringstest..

I detta examensarbete har ett system för navigering och styrning av ett autonomt fordon implementerats. Syftet med detta arbete är att vidareutveckla fordonet som ska användas vid utvärdering av banplaneringsalgoritmer och studier av andra autonomifunktioner. Med hjälp av olika sensormodeller och sensorkonfigurationer går det även att utvärdera olika strategier för navigering. Arbetet har utförts utgående från en given plattform där fordonet endast använder sig av enkla ultraljudssensorer samt pulsgivare på hjulen för att mäta förflyttningar. Fordonet kan även autonomt navigera samt följa en enklare given bana i en känd omgivning.

Social indexing is an approach to manual indexing of web content. The purpose of this master thesis has been to investigate terminological and conceptual consistency in social indexing of web content. Conceptual consistency was investigated/measured focusing on synonyms and (the use of) singular and plural forms of words. In order to measure consistency in social indexing data were obtained from the Delicious website. The data set consists of five indexed objects, 3001 tags and 239 users.

Denna rapport har jämfört olika path tracking-algoritmer för att se vilken som presterar bäst för spelagenter som färdas i konstant hastighet. Tre vanliga path tracking algoritmer som ofta används inom robotik har valts ut för undersökningen, Follow The Carrot, Pure Pursuit och Vector Pursuit. Algoritmerna har implementerats i C# och simuleringarna har genomförts i Unity 4.0. Path tracking-algoritmerna har testats på ett antal olika vägar för att se hur de lyckas följa vägen. Av simuleringarna så visar det sig att Pure Pursuit och Vector Pursuit presterade likvärdigt för spelagenter i konstant hastighet samt att de presterade bättre än Follow The Carrot..

Previous research has found an increased transmission of stock movements in Europe, partly caused by the establishment of institutions as the EU and the EMU. The purpose of this paper is to find the possible impact from the EU and the EMU concerning the evolution of international transmission of stock market movements, on four Scandinavian markets, Denmark, Finland, Norway and Sweden. The research is based on primary data, existing theories and earlier studies regarding international transmission of stock market movements. The examined method is a VAR (Vector autoregressive model) including a 10x1 vector of variables. Furthermore the tests considered are correlation, granger-causality, variance decomposition and impulse response.

An attempt was made to GFP-tag the effector proteins of AvrLm6 and AvrLm4-7 using the GFP-tagging gene knockout method (GGKO) developed by Saitoh et al. (2008) in order to determine whether or not they are secreted. Successful pETHG-(target)KO vectors were not generated. The protocol was examined for potential errors. Fatal errors were pinpointed to the ligation reaction and the transformation required to generate and propagate the desired vector pETGH-(target)KO.

Under Swedish tax law; the general clause in the Tax Avoidance Act is a method to prevent tax evasion. The purpose of the general clause is to prevent any tax avoidance procedures that the legislator has not been able to foresee. For the general clause to be applicable, four prerequisites need to be met. This thesis analyses the fourth prerequisite based on the principle of legality. The prerequisite concludes that a determination of the tax base, based on the procedure in question, is in conflict with the purpose of the legislation.

After the storm Gudrun in 2005, the Swedish Transport Administration started clear-cutting of railroad corridors to reduce the risk of trees falling down on the tracks. Simultaneously, train accidents with moose and roe deer have become more frequent and the costs for consequent delays and repairs of engines are of growing concern. There is reason to assume that tree-clearance of railroad corridors may have contributed to an increase in number of accidents with moose and roe deer because the cleared areas provide attractive forage and thus may attract wildlife. The objective of my study was to investigate how clearing of trees affected the number of accidents with moose and roe deer. I compared deer-train collision frequencies before and after clearance of the selected railroads and compared these with uncleared control railroads in a BACI (before-after control-impact) approach.

Servicescape is a research area within service management which processes the effect that the environment has on the service experience. The purpose of this essay is to find out how servicescape, with focus on the ?background music?, affects customer behavior in a clothing retail store. Through manipulation of the background music?s tempo the essay aim to explore to what extent this part of the servicescape a) affect the customers approach and avoidance behavior, b) is affected by customers with a hedonic or utilitarian shopping behavior, c) affects pleasure, arousal and dominance perceptions for the customer, and d) how the servicescape is perceived.Key words: Servicescape, approach-avoidance behaviour, pleasure, arousal, dominance, hedonic-utilitarian behaviour..

Adaptive Resource Allocating Vector Quantizer (ARAVQ) är en teknik för datareducering för mobila robotar. Tekniken har visats framgångsrik i enkla miljöer och det har spekulerats i att den kan fungera som ett generellt datautvinningsverktyg för tidsserier. I rapporten presenteras experiment där ARAVQ används som datareducerare på en artificiell respektive en fysiologisk datamängd inom en datautvinningskontext. Dessa datamängder skiljer sig från tidigare robotikmiljöer i och med att de beskriver objekt med diffusa eller överlappande gränser i indatarymden. Varje datamängd klassificeras efter datareduceringen med hjälp av artificiella neuronnät.

For many decades the increase in traffic volume, expansion of highways and infrastructure has lead to an increase of wildlife vehicle collisions which are unfortunately very common in many countries today. They cause great deal of material damage and even kill humans or wildlife. Measures in the form of warning signs, under- and overpasses and fencing have been implemented for a long time with the help of observation by hunters and collisions sites. However this study focuses on the moose?s perspective and the variables that, both spatially and temporally, could have an effect on why and when moose are close to certain types of roads.

Personer som genomgått en traumatisk händelse befinner sig i riskzonen för att utveckla post-traumatic stress disorder (PTSD), som innebär en stor livsbegränsning och ett stort lidande. Dagligen möter hälso- och sjukvårdspersonal personer som ännu ej diagnostiserats och det är därför av vikt att kunna identifiera PTSD-symptom. Syftet med litteraturstudien var att undersöka samband mellan olika trauman och PTSD-symptom enligt diagnostiseringssystemet DSM IV. Studien grundades på en deduktiv ansats och resultatet bestod av 15 vetenskapliga artiklar som granskades. Resultatet behandlade DSM IV:s tre symptomkluster: re-experience/intrusion, avoidance och hyperarousal.

The aim of the Master?s Thesis work is to study and develop algorithms for autonomous travel of a UGV (Unmanned Ground Vehicle). A vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas.

Background: Previously research shows that people treated conservatively can have reduced foot function after Achilles tendon rupture. However, there are few qualitative studies in the subject, so this essay is written to provide a deeper understanding of how these people feel about their foot function one to two years after the injury.Purpose: Investigate how people perceive their foot function after conservative treatment one to two year after Achilles tendon rupture and if they have an avoidance behavior in their everyday lives.Method: Four people who suffered from Achilles tendon rupture participated in this qualitative study. The study was conducted with semi-structured interviews, which in turn were processed using qualitative content analysis.Results: The perceived foot function is today varied in terms of mobility, strength and pain according to the participants. They feel difference in their everyday life in comparison with before the injury. It appears that participants have avoidance behavior when it comes to the situation of injury.
