Dockless bike-sharing is growing in many cities around the globe. At the same time issues related to this type of urban mobility such as illegal or improper parking behavior are becoming more frequent. The implementation of parking zones delineated by geofences has been discussed as a possible solution for these issues. This master thesis project aims to develop a GIS-based multi-criteria analysis
Introduction: A new method for separation and determination of Glyphosate and Glufosinate alongside their respective major metabolites aminomethylphosphonic acid and 3-(methylphosphinico)propionic acid was found then tested in spiked soil and surface water. Background: Most methods today require derivatization for determination and separation of these compounds. Methods without derivatization rel
An increased proportion of trips made by bike is important part of a more sustainable transportation system. It provides benefits both at an individual and societal level – especially when replacing trips that would otherwise have been made by car. To get an understanding of what influences cycling, a statistical analysis is carried out that shows links between socio-economic factors, the physical
Interpreting EEG measurements is of great relevance, both for developing underlying neuroscientific theory and improving existing applications. In this study, two networks with different approaches to time-frequency analysis and feature selection are compared on simulated and real data for semantic and emotional perception. The first network uses the Morlet wavelet transform to achieve adaptable f
En genomgående trend i alla företag och industrier är att deras förmåga att producera data växer fortare än deras förmåga att lagra den, och detta gäller även hos CellaVision som producerar mikroskopiska blodcellsbilder. Lösningen är att komprimera bilderna med konsekvensen att viss information förloras. Vi har använt oss av djupinlärnings-metoder för att rekonstruera den försvunna datan i bildernThis thesis investigates the use of convolutional neural networks as a reconstruction or JPEG- deblocking model for JPEG-compressed blood cell images, needed due to the well known block artifacts caused by JPEG-compression. CellaVision develops automated microscopy for blood analysis that detects and classifies blood cells from images. The automated analysis is carried out on high resolu- tion mic
År 2018 införlivades Europeiska Unionens dataskyddsförordning i svensk rätt och dataskydd som ämne fick en allt större uppmärksamhet i media och i debatt. Dataskyddets framväxt började dock tidigare än så och är en viktig fråga för både enskild individ som för stat och företag. Tack vare en snabb teknisk utveckling och smarta algoritmer är personlig information en allt mer värdefull tillgång hos In 2018, the European Union's General Data Protection Regulation (the GDPR) was incorporated into Swedish law, and data protection as such was increasingly noticed and given attention in the media. However, the emergence of data protection began a lot earlier than 2018 and is an important matter as for both individuals such as the state and companies. Through rapid technological development a
Företag har genomfört stora förändringar efter att den svenska Folkhälsomyndigheten införde rekommendationer om hemarbete till följd av Covid-19 pandemin. Distansarbete har ökat kraftigt i omfattning och prognosen är att även efter pandemin kommer det flexibla arbetssättet kvarstå. Syftet med det här examensarbetet är att undersöka vilka eventuella utmaningar som distansarbete medför för framtidenCompanies have implemented major changes due to the recommendations of remote work introduced by the Swedish Public Health Agency as a result of the Covid-19 pandemic. Remote work has rapidly increased, and the forecast is that this flexible working method will remain. The purpose of this thesis is to examine which challenges remote work entails for offices in the future, and with this data presen
Mortgage loan providers estimate the credit risks it caries when approving a mortgage loan to their clients. Further, defaulting a mortgage loan is a risk that has been calculated through decades using statistical models. By using entries at the time of a mortgage application, the goal of the thesis is to com- pare the accuracy between logistic regression and Support Vector Machine in predicting
Background: Operations planning and control has undergone an extensive shift from an individual company focus to a complete supply chain focus which has required a new common approach for supply chain planning and control to evolve. Increasing competition and globalization has created complexity in supply chain planning and integration since it requires a new cross-functional approach. To handle s
This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. The investigation begins with the application of varnishes using a spray gun, brush, and dip coating followed by spraying equipment from Sprayi
Svenska hästar rankas som bland de bästa i världen och hästnäringen omsätter mer än 72 miljarder kronor per år. Beroende på i vilken roll säljaren agerar så blir olika lagar tillämpliga vid köp av häst. Är säljaren en näringsidkare hamnar man i konsumentköplagen, medan om den är en privatperson så blir köplagen tillämplig. Beroende på vilken lag man hamnar i kan utfallet vid en felbedömning se oliSwedish horses are amongst the top in the world and the revenue of the industry is over 72 billion Swedish crowns per year. Depending on the role the seller is acting as, different laws will apply. If the seller is an entrepreneur, Consumer Sales Act will apply, but if it’s a private person The Sale of Goods act will be applicable. Depending on which law you apply, the outcome could be different.
Syftet med denna studie var att undersöka psykometriska egenskaper för Compassion fatigue inventory (CFI), som ett instrument för att mäta compassion fatigue hos lärare. Vi undersökte även om nivån av compassion fatigue kunde predicera lärares benägenhet att agera i en mobbningssituation. En konfirmatorisk faktoranalys utfördes och vi fann att den gav otillräckligt stöd för den tre-faktorstruktur The purpose of this study was to investigate the psychometric properties of the Compassion Fatigue Inventory (CFI) as a tool for measuring compassion fatigue among teachers. We also examined whether the level of compassion fatigue could predict teachers' propensity to act in a bullying situation. A confirmatory factor analysis was performed, and we found that it provided insufficient support f
Cross-laminated timber (CLT) is an environmentally positive building material with high stiffness and load-bearing capacity. In combination with a low self-weight, CLT is a beneficial material to use for the load-bearing structure of high-rise buildings. In this project, the lateral stabilization of a CLT building subjected to a wind load is analysed through several modelling approaches. The effec
Hur kan restmaterial från stålindustrin användas för att minska uttaget av naturresurser? Ett vanligt användningsområde av exempelvis stålslagg är som konstruktionsmaterial vid sluttäckning av deponier. Genom att använda slagg för detta ändamål kan mängden deponerat material minska, samtidigt som man kraftigt minskar behovet av vanligt täckmaterial, såsom grus och jord. Stålslagg kan även användasA variety of excess material is produced in the processes used in the scrap-metal based steel industry. The largest stream of material, by volume, is steel slag. Since slag material has very different properties and wide differences in its chemical composition its usage can be found in different sectors. The increased understanding of slag and its properties has made companies less prone to divert
