Idag dimensioneras konstruktioner dels för permanenta laster såsom egentyngd, dels för variabla laster i form av snölast, vindlast och nyttig last. Mot bakgrund av pågående klimatförändringar och kraftiga regnoväder på senare år, exempelvis i Malmö hösten 2014, kan även vattenlaster få en större betydelse i framtiden. I synnerhet på låglutande och flacka tak finns det risk för betydande mängder kv

In this work, inverse diffusion equation and Monte Carlo methods are used in conjunction with diffuse reflectance spectroscopy to develop a protocol for evaluating the chromophore compositions of tissue mimicking liquid phantoms. A novel two spectrometer system is used which provides real time calibration of any intensity fluctuations of the light source. The calibration of this setup is investiga

This study aims to investigate and explain the portrayal of refugees in Swedish media, and to use the media as a way of understanding society at large. The analysis is based on newspaper articles written during times when nationalist parties have been in parliament in Sweden, the periods being 1990 to 1995 and 2010 to 2015. By looking at how the media portrays and reports on refugees through the t

Background. Lack of knowledge why consumers carry out unsustainable fashion practices inspired the following thesis to explore the phenomenon from a socio-cultural perspective. Although previous studies in green consumption explored to some extent how and why people consume green products, the research in the field is still underdeveloped. An extensive literature review demonstrated a limited unde

För att klimatförändringarna inte ska bli för stora har Sverige som mål att till år 2020 reducera utsläppen av växthusgaser med 40%. För att klara detta arbete behöver Sveriges kommuner hjälpa till med lokala mål och åtgärder, och Ängelholms kommun har då valt att i sin miljöplan bestämma att kommunen år 2021 ska vara helt fossilbränslefria i alla transporter som kommunen äger eller brukar. SyftetSweden has a goal to reduce the emissions of greenhouse gases with 40 % until 2020 to prevent the climate change from becoming too big. Too succeed in this work, the Swedish municipalities need to help with local goals and arrangements. The municipality of Ängelholm has chosen to decide in its environmental action plan that the municipality by 2021 is going to be completely free of fossil fuels in

Comparing with traditional linear regression methods that used to monitor vegetation trends, a nonlinear regression algorithm (PolyTrend) developed by Jamali et al. (2014) can provide more accurate information of vegetation trends by fitting a polynomial line with a degree of up to three for ASCII-formed time-series NDVI (Normalized Difference Vegetation Index) dataset of a single pixel. To extend

Planar antennae have become very popular owing to their relative ease of manufacture and unobtrusive nature (they are conformal to surfaces) especially with regard to certain devices such as smart phones, watches and fitness gadgets. Although the fractional bandwidth of planar antennae is small, the actual bandwidth in absolute terms is high owing to the higher centre frequencies used and proves u

This Master Thesis was performed for Sandvik SRP in collaboration with the Institution for Industrial Production Faculty of Engineering at Lund University. Tool wear is one of the main cost drivers in the mining industry. By being able to characterize what kind of rock involved, you can choose a more beneficial tool material to minimize the wear and thereby reduce the maintenance costs. The purpos

Purpose The purpose of this research paper is to investigate the phenomenon of destructive entrepreneurship from a contextual perspective, by conducting a narrative study in a cosmopolitan city of Sweden. A narrative story is constructed based on the life story of a drug dealer. This narrative is used as input in interviews with respondents representing different political and social organisations

Nitrification-denitrification process, which is the most commonly used method for nitrogen removal from wastewaters, is energy demanding and contributes very much to the the carbon footprint of wastewater treatment. One of the alternative methods for nitrogen removal is the nitritation-anammox process. Nitritation-anammox has been implemented successfully in sludge liquor streams and industrial wa

Success through product differentiation A popular science article based on the Master Thesis “Development of Replenishment and Planning Strategies” by Fredrik Kapellner and Felix Kaltea, 2016. Matching supply with demand is a continuous struggle, now more than ever since customers expect deliveries within days after placing an order. In order for a company to be profitable in these demanding time

Quantitative proteomics is concerned with measuring the abundances of different proteins in biological samples. In the shotgun approach, proteins are digested by an endoprotease into several smaller peptides, which are then separated by liquid chromatography (LC) and subsequently detected and quantified by a mass spectrometer. In this work, a method for determining the relative abundances of prote

Within business practice, the concept of pop-up retailing has already grown out its status of just being a trend, and has developed into a highly accepted and widely used retail format in a variety of business sectors. Despites this rising popularity, academic research has given rather little attention towards the phenomenon of temporary retail sites. Due to this research scarcity, the purpose of

I den här studien utformades, genomfördes och utvärderades en intervention med hjälp av bild. Syftet med studien var att nå en fördjupad förståelse för hur nio kvinnliga studenter upplevde denna intervention. Utifrån den psykosocialt inriktade behandlingsmetoden TTM (Tree Theme Method) konstruerades en intervention bestående av en mindfulnessinspirerad övning, individuellt målande och samtal i gruIn this study an arts-based intervention was designed, conducted and evaluated. The aim of the study was to gain a deeper understanding of how nine female students experienced this intervention. Based on the psychosocially oriented treatment method TTM (Tree Theme Method) an intervention was constructed, consisting of a mindfulness-inspired exercise, individual painting and a group discussion. The

We consider the problem of estimating the location of a number of wave-emitting sources, known as the direction of arrival problem. We consider both the two- and three-dimensional case. The method we use works for equally as well as unequally spaced sensors, that are located in (possibly) non-square regions. In the case of wideband signals we show how measurements from multiple frequencies can be

Caches today are an important part of mitigating the performance gap between processors and memory which has increased during the last 50 years. Cache policies are vital for the performance of caches and their mission is to select the data which should be contained in the cache and are therefore important for the performance of processors. Graphics processors are very memory bandwidth intensive an

Att kunna följa och spela in handbollsmatcher automatiskt skulle kunna vara ett kraftfullt verktyg för både spelare och tränare vid utvärdering av lagprestationer. Automatisk inspelning skulle aven kunna användas för att webbsända matcher. Även om elitmatcher i handboll ofta spelas in, är syftet med inspelningarna inte att ge tränare data om hur laget har spelat. När idrott spelas in för att sändaThis thesis presents and evaluates different models aimed at tracking the play in handball matches. The tracking is designed to be used with automatic broadcasting of handball matches without any camera operator present. To solve this problem the Kanade-Lucas-Tomasi tracker is used to generate data of player movements on the handball court. From the tracker data, features are extracted and used as

I denna studie har data över genereringen av återvinningsbart avfall från EU-länder analyserats och olika möjliga förklarings faktorer har undersökts genom en kombination av två olika statistiska metoder. Syftet var att identifiera några av de största faktorerna till uppkomsten av återvinningsbart avfall, och utifrån dessa faktorer, hitta en linjär funktion som beskriver genereringen av olika återIn this study, data of the generation of recyclable wastes from the EU member states, and possible explaining factors for describing this generation, are examined through a combination of Probabilistic Principal Component Analysis (PPCA) and multivariate regression analysis. The purpose is to identify some of the biggest contributors to the generation of recyclable wastes, and, based on these cont
