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
This thesis used the qualitative textual analysis research method to study the blog content and comments of the DiDi Hitch algorithm controversial published by China News on Weibo. The purpose was to explore netizens’ views on gender bias and conflict in artificial intelligence consumption scenarios, as well as the drawbacks of DiDi Travel when adapting to artificial intelligence algorithms. In th
Aim: The aim of this study is to explore why German millennials use the green search engine Ecosia, as the organisation is experiencing considerable growth in Germany. Theoretical Perspectives: This thesis adopts well-established theories such as the Theory of Planned Behaviour, the Value-Belief-Norm Theory, and the Social Influence Theory. Moreover, the theoretical perspective consists of the Mu
Under 2020 och 2021 har en stor del av organisationer i Sverige och runt om i världen tvingats lägga om sin verksamhet till arbete på distans till följd av Covid-19 pandemin. Detta har lett till nya utmaningar inom inte minst informationssäkerhet, där policys och riktlinjer i många fall varit anpassade för arbete i organisationernas lokaler. Då den största risken inom informationssäkerhet är den m
This study investigates the cyber security threats and risks that are associated with forced teleworking during the period of Covid-19, when organizations have been forced to telework. Three different main aspects from two theories have been crucial when investigating the threats and risks associated with forced teleworking, which are the Social, Technical and Risk Tolerance aspects. This study
The overall purpose of the present thesis is to explore how participatory development architecture and the good governance principles of cooperation and consensus have depoliticised disability as an issue and have re-shaped the discourses and actions of organisations of and for disabled people in Georgia. Through the lens of the theory of post- politics, the research analyses the application of go
Bakgrund: På grund av otillräcklig stöttning och anpassning inom grundskolan når mindre än hälften av barnen med autismspektrumtillstånd (AST) kunskapsmålen. Internationella erfarenheter och studier av arbetsterapeutiska interventioner för att stödja dessa elever visar på positiva effekter avseende aktivitetsutförande och skolresultat. I Sverige är dock användningen av arbetsterapeutiska interventBackground: Due to insufficient support and adaptions in compulsory school, less than half of the children with autism spectrum disorder (ASD) reach their academic goals. International experiences and studies of occupational therapy interventions for these children show positive effects regarding occupational performance and school results. In Sweden, however, the use of occupational therapy inter
