Attenuation of the microwave signal used in the Global Positioning System (GPS) due to interaction with building structures complicates the task of accurate indoor positioning. For this reason, research on alternative approaches is being performed at universities and companies worldwide. The Global Indoor Navigation (GIN) research project in Lund is one such initiative, where the main goal is to p
I svensk rätt råder fri bevisvärdering. Med fri bevisvärdering menas att domstolen inte är bunden av legala regler om viss metod eller visst tillvägagångssätt när denne värderar bevis. Endast ett fåtal hållpunkter till ledning för domstolen har satts upp i förarbeten, resten lämnas till rättstillämparen att fastställa. Vid bevisvärderingen använder sig domaren av allmänna erfarenhetssatser för attThe evaluation of evidence is free in Swedish law. A free evaluation of evidence means that the court is not governed by any legal rules which makes demands on a specific method or procedure while evaluating evidence. In the preparatory work there has only been established a few points of guidance, the rest is left to the legal practitioners to establish. When evaluating evidence, the judge uses c
Dagens samhälle kräver mycket energi för att fungera. Solljus är en fantastisk förnyelsebar energikälla och med solceller går det att ta till vara på denna energin och använda den i form av elektricitet. När solljus träffar en solcell absorberas dess energi i materialet, detta genererar laddningsbärare som är positiva (hål) och negativa (elektroner) som kan driva en ström. Eftersom de olika laddniSolar cells are a potent and renewable alternative to generate electricity. Through absorption of energetic photons electrons are excited generating electron-hole pairs or charge carriers and through separation of these charge carriers a current can flow through the device. In this project Molybdenum oxide (MoOx) is tested as a hole selective contact in n-i-p Indium phosphide (InP) nanowire solar

The purpose of the study has been to investigate social workers' experience of working with and supporting women who have been exposed to domestic violence by men during covid-19. We were also interested in how the social workers reasoned about how covid-19 affected this group. The study has a qualitative approach, and eight semi-structured interviews were conducted with social workers at vari
Gene expression profiling can be used to classify lung adenocarcinoma tumors into molecular subtypes that also correlate with patient prognosis. Knowing these subtypes can help clinicians save lives by directing surgery and adjuvant therapy efforts, provided adequate clinical validation. It is less well-known how generalizable prognostic gene signatures derived in one malignancy are in a pan-cance
LDMX is a fixed target experiment designed to search for light dark matter. The experiment will search for dark matter signatures using missing momentum and energy in events with electrons scattering in the target. Part of the experimental setup in this search is a high granularity electromagnetic calorimeter to accurately measure the energies of recoil electrons. In this thesis artificial neura
I studien undersöktes associativ språkinlärning via Virtual Reality (VR) och jämfördes sedan med en mer traditionell ordinlärning via en datorskärm, för att se om det förekom någon skillnad i inlärningen mellan dessa. Syfte. Studien syftade till att undersöka om inlärning av ett nytt språk gynnas av associativ inlärning med flera av våra sinnen genom VR. Vår hypotes var att språkinlärning kan gynThe study examined associative language learning through Virtual Reality (VR) and then compared it to more traditional word learning through a computer screen, in order to see if there was any difference in learning between these two. Purpose. The aim of this study to investigate whether learning a new language benefits from associative learning, with several of our senses, through VR. Our hypoth
The aim of this work was to develop a stable and reproducible argon milling process for InAs nanowires to remove the native oxide layer that increases electrical resistance. This was done by identifying a few milling parameters and studying them in relation to the milling rate of silicon dioxide (SiO2). After further experiments with different milling parameters, a set of parameter values was foun
Katalysatorer har många funktioner och applikationer, till exempel som enzymer i vår kropp eller katalysatorer i bilar. En katalysator är helt enkelt en substans som sänker den energi som krävs för att en kemisk reaktion ska ske och därmed öka reaktionshastigheten. Själva katalysatorn förbrukas inte under reaktionen. Inte alla katalysatorer hjälper alla reaktioner, olika katalysatorer har olika anA model V2O5/ anatase TiO2(101) SCR catalyst is studied with the purpose of developing and understanding the reaction mechanism through which this catalyst reduces NOx. Several reaction mechanisms have been proposed for this catalyst in the past, but there is still no agreement on which of these describe the reaction the best, if any. Two coverages of 2 ML and 0:33 ML V/ anatase TiO2 and the oxida
Saturated laser-induced fluorescence (saturated LIF) has been the topic of some research, however mainly regarding laser diagnostic methods conducted on flames. A few papers have discussed saturated LIF with the purpose of producing saturation curves of different fluorescent elements. The utilised methods in these cases have involved manually increasing the laser intensity and detecting the fluore
Jordbruket har förändrats enormt under de senaste hundra åren, det har blivit större maskiner och små åkrar har slagits ihop till större åkrar. Detta har revolutionerat matproduktionen men samtidigt gjort landskapet mer likartat. Övergödning av vattendrag, utsläpp av växthusgaser och förlust av biologisk mångfald är endast några av de negativa miljöeffekter som det moderna jordbruket har resulteraThis study was done to get an understanding of how tillage effects biodiversity in agriculture soil. Therefore, this study focused on the soil organisms and various physical and chemical processes that can affect them. Soil organisms are crucial to agricultural landscapes as they perform biological processes that improve soil structure, nutrient cycling and decomposition. To ensure food produc
In workplaces, a lot of knowledge is lost when colleagues change positions. What was once obvious to one person can be incomprehensible to the next. This problem has been encountered by Probation Labs Sweden AB with their biochemical instrument, Labbot. Labbot facilitates researchers in automating their protein analysis. It works like a multi-tool where users can perform one or several tasks in a
Glucose transporters, known as Gluts, play an important role in facilitating the transport of sugar across the cell membrane. Of these, 14 types are known, one of which is Glut3, which is highly expressed in the brain, testicles and nervous system. Its importance lies in the fact that it is responsible for the uptake of glucose in cells with high sugar requirements, such as neurons. Glucose uptake

Vidare kommer uppsatsen att analysera de utmaningar som är förknippade med ett sådant avslutande. I granskningen av komplexiteten som omger avslutandet av en ockupation kommer 2005 års tillbakadragande från Gaza, samt ockupationen av Irak meThis thesis aims to investigate the law of occupation under international humanitarian law, specifically focusing on the beginning and ending of an occupation. The thesis will also explore the challenges associated with its termination. By examining the complexity regarding the ending of an occupation, the 2005 “disengagement” from Gaza and the occupation of Iraq 2003-2005, will be used. The thesi
Inom partikelfysik, går de teoretiska och experimentella aspekterna hand i hand. För att förstå hur partiklar växelverkar med varandra och kunna förstå experimentella resultat, behövs en teoretisk modell av interaktionerna. Feynmandiagram erbjuder exakt detta, ett verktyg för att simpelt visualisera partikelprocesser. Med Feynmandiagram är det möjligt att förstå vilka processer som är möjliga och This thesis explores the simplifications the chirality-flow formalism brings the calculations of scattering amplitudes in massless QED. We explain Feynman diagrams and chirality- flow diagrams to emphasize how the calculations of scattering amplitudes differ. It is studied how applying the chirality-flow formalism simplifies the calculations. The work focuses on calculations with and without exter
Matsvinn är ett stort samhällsproblem. Om förpackningen inte håller den nivå av kvalitet som krävs så slängs den under produktionen, tillsammans med det livsmedel den skulle skydda. Vissa förpackningar har korkar, som hjälper till att återsluta förpackningen. Om plasten i korken har fel egenskaper uppstår det ibland problem i produktionen. Detta projekt har tagit fram två sätt att undersöka plasteFood packages preserve foodstuff during storage. Some packages have caps, some of which have internal pull rings for easy removal of a membrane that extend the shelf life. The pull-rings are injection molded directly onto the package in the filling machine at the customer site. Any defect in the pull ring causes filled packages to be discarded at a significant cost to the supply chain. Some batche
