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
Informationsteknologi med dess informationssystem har bidragit till att många aspekter i vår vardag har effektiviserats och förbättrats. Både för privatpersoner och företag. Information har blivit lättare att administrera, tid har sparats och våra dagliga processer har inom många aspekter blivit smartare. Denna studie ämnar illustrera hur informationssystem har bidragit med effekt inom vården. Mer
Problem: I teorin kan idén om artikelkommentarsfält på nyhetssajter framstå som ett ideal - ett lättillgängligt forum och en gemensam plattform för diskussion och debatt om samhällsfrågor. I praktiken är det inte alltid så idealiskt. Hot om våld och rasistiska uttalanden är sådant som går att hitta i kommentarstrådarna. Hur hänger de här två bilderna av teori och praktik ihop? Metod och material
Purpose. The survival rate in the Fashion Industry (FI) is dramatically low and the reasons remain unclear. This research aims to identify the main challenges that the fashion entrepreneur faces when entering the FI and how relevant these are through the fashion start-up process. Methodology. Qualitative and comparative multi-case study. The research structures the relevant peculiarities, that pr
Psykiska sjukdomar är ett globalt problem och räknas idag som ett av de stora folkhälsoproblemen. Idag lever 38,2% av Europas befolkning med psykisk ohälsa och det är inte bara personen med psykisk sjukdom som berörs utan även personens närstående. Studien genomfördes som en litteraturstudie vars syfte var att ta del av den forskning som har undersökt närståendes erfarenheter av den psykiatriska s
