This thesis proposes a machine-learning-supported pipeline which, put together, provides an estimate of roof surface area for solar panel installation. This pipeline is comprised of roof segmentation based on images and digital surface models and provides subsequent identification of key measurements such as roof length, roof width and roof angle. Obstacles belonging to a roof are also identified

Organisations increasingly adopt digital technologies in order to assist and improve the efficiency of their decision-making processes. Industries, including banking, need to increasingly adapt to the world of digitalization. The amount of data that has to be processed in the banking industry is increasing exponentially, and digital technology represents valuable solutions to processing this data

An increased understanding of the negative impacts of animal-based proteins, on both environment and health, has led to a rise in the demand for plant-based proteins. To meet the demands, conventional crops must be efficiently utilized. One possible crop is oat which is a good source of protein, fibre, and fat, but is currently mainly used for animal feed. To better utilize the proteins in oat, th

Början av 1900-talet såg en oerhörd utveckling av nya forskningsområden inom fysiken. 1905 lade Einstein grunden för den speciella relativitetsteorin, som revolutionerade hur fysiker ser på själva tiden och rummet genom att föreslå att vi kan behandla de båda på samma sätt. Samtidigt växte kvantfysikens värld fram i jakten på en beskrivning av vår verklighets allra minsta beståndsdelar. KvantfysThis thesis derives the explicit form of the elements of the (1/2,1/2) representation of the Lorentz group, by actually performing a direct product of the chiral (1/2,0)- and (0,1/2)-representations. The Lorentz transformations of fourvectors are thereafter recovered from this direct-product representation, allowing the derivation of a transformation matrix between the fourvector- and direct produ

Abstract Purpose: The purpose of this thesis is to investigate how different types of fans experience personalization in sports marketing and to analyze how each Fan type can be motivated by understanding how their fan experience could be optimized further. Methodology: This study was a qualitative study. The study was carried out using an abductive approach where literature was combined with empi

In this thesis a number of methods for image classification are investigated. The main goal is to explore an approach based on functional data analysis and compare it with Neural Networks. The main idea is to view each image as a function and then capture the most important variation of each image class through Functional Principal Component Analysis. For comparing the methods the cifar10 dataset

After hundreds of years of urbanization a new trend is here. In Sweden, people are now leaving the big cities for a life in the countryside. How can urban designers work with rural areas and how do we do urban design in a rural way? This thesis investigates rural design in a Swedish village called Björkvik.

The village of Vilhelmina in South Lapland, Sweden is declining. Despite the general trend of urbanization more and more people are leaving Vilhelmina which have resulted in economic insecurity and a disassembly of basic public services and buildings. With new global trends like globalization, digitalization and global heating, this could potentially be changed and the thesis aims to investigate a

Lipase is one of the most useful enzymes in food industry, which can catalyze the hydrolysis and the synthesis of esters. However, the high cost due to the poor operation stability of lipase hinders the wide use of it. In present research, the stability of lipases in aqueous systems has been thoroughly studied, while research on lipases in non-aqueous systems is limited. In this work, the secondar

Low-Density Parity-Check (LDPC) codes are one of the most popular codes used in nowadays’ communication due to their high coding efficiency at low decoding complexity. With these characteristics, LDPC codes are suitable for high-speed information transmission systems. The widely used decoding algorithm for LDPC codes is Belief Propagation (BP) decoding with which the performance of LDPC codes can

Food Waste is a global issue concerning the environment, resources, social justice and economy. Despite being so pressing, around one-third of food produced is discarded worldwide. Meanwhile, food waste is incredibly complicated, requiring collaborations of all stakeholders and various innovations. Too Good To Go (TGTG) utilizes technology to bridge consumers and food business and save food waste

OPO är en viktig strukturerad lipid för bröstmjölksersättning. I denna rapport beskrivs en ny metod för syntes av denna viktiga lipid med hjälp av en tvåstegs-enzymatisk alkoholys-esterifiering. Denna process är komplett med syntes i två steg, intermediär upprening och downstream processing.In this thesis work a simplified, solvent-free, two-step enzymatic method for producing tailored lipids for infant formula with more than 75% of palmitic acid in sn-2 position is described. This simple enzymatic process concept could be a future route towards OPO production or other tailored lipids with palmitic acid in position sn-2

Det sen-Triassiska massutdöendet (STM) som inträffade för omkring 201 miljoner år sedan är känt som ett av ”de fem stora” massutdöendena under Fanerozoisk tid. Massutdöendet påverkade främst marina ekosystem, vilket resulterade i en global minskning av ryggradslösa djur och utdöendet av konodonterna. Orsaken till STM kan anknytas till utbrotten av den Central-Atlantiska magmatiska provinsen (CAMP)The end-Triassic mass extinction (ETME) which occurred around 201 Ma is known as one of “the big five” mass extinction events of the Phanerozoic eon. Its effects were most severe on marine ecosystems, resulting in a global decline of invertebrate taxa and the complete extinction of the conodonts. The cause of the ETME can be attributed to the volcanic activity of the Central Atlantic magmatic prov

The purpose of this study was to illustrate how youth crime is constructed by three different political parties in Sweden; Moderaterna, Socialdemokraterna and Vänsterpartiet. The data in this study consists of several official political documents such as interpellations, motions and proposals. The documents were analyzed using perspective analysis, which stems from the social constructionist persp

Finding vulnerabilities in open source software is an important part of software security. Software security is in turn a vital part in risk management and making risk assessments. The purpose of this thesis is to help organisations make decisions about vulnerabilities they have in their software programs by helping them make their own risk assessment. Our research uses the Common Vulnerability Sc

This master thesis is performed in collaboration with Orkla Foods Sweden AB. The aim with this study is to investigate and compare nutritional contents in processed and homemade foods by investigating three selected ready meal products from the product range of Orkla Foods; meatballs, potato mash and pasta bolognese. This originates in a general perception that foods produced in a large-scale indu

Increasing waste electrical and electronic equipment (WEEE) has become a global issue that raises social and environmental impact concerns, and recycling and using recycled materials is proposed by policymakers and academics as a solution. Nevertheless, barriers still exist and result in low collection and recycling rates and underdeveloped recycling markets. This paper aims to first understand ho

Att utbilda och fortbilda sina anställda är en viktig process för företag. Det krävs mer och mer för att företag ska hålla kvar sina anställda och möjligheten att utvecklas och fortbildas är något anställda ser positivt på. När samhället har digitaliserats så har processerna förändrats och digitala systemstöd har blivit en vanlig del av HR-avdelningens arbetsuppgifter. Ett systemstöd som används f
