In the next 30 years the world’s population is expected to increase by two billion people, resulting in a growing demand for natural resources and rising greenhouse gas emissions. In order to face these challenges, society needs to improve resource efficiency while producing less waste. In Sweden there is a large amount of waste originating from the restaurant industry. Previous studies have exami
Utsläppen från transportsektorn står för en betydande del av Sveriges totala koldioxidutsläpp. Fram till år 2030 vill regeringen att växthusgaserna från transportsektorn ska ha minskat med 70 procent utifrån år 2010s nivåer. Därtill vill man år 2045 att Sverige har nettonollutsläpp. För att inom transportsektorn lyckas med dessa mål kommer ett nyttjande av en kombination av lösningar vara essentie
Myelin water imaging, MWI, is a non-invasive method used for quantifying the amount of myelin in the brain that can aid the understanding of brain plasticity and neurodegenerative diseases, such as Multiple Sclerosis (MS). Conventional MWI is done at a field strength of 3 T, though there are indications that higher field strength may lead to higher resolution images. We investigate the use of isot
Knitting is a craft that has existed for many years giving it a rich history. The popularity of knitting has never been steady and has risen and fallen throughout the years, albeit now readily associated with older generations. It is safe to say that knitting is currently going through a revival in Denmark, especially young women have picked it up, seemingly taking the popularity of knitting to ne
The aim of the thesis is to evaluate solutions to the class imbalance problem using real world data sets with varying degrees of class imbalance. The analysis is limited to binary classification. Three large data sets relating to credit card fraud, vehicle insurance and heart disease are used for the analysis. Several methods are compared and evaluated. Logistic regression, SVC and decision trees
Thesis Purpose: The purpose of this research is to find out which Environmental CSR concerns addressed by corporations impacts consumer purchase intention. This research also aims to examine whether the cultural dimension of collectivism/individualism has an impact on consumers' purchase intention toward CSR. Theoretical perspective: The theoretical perspective was based on the earliest theor
Asfaltbeläggningar behöver fortlöpande repareras och slutligen bytas ut efter nötning och sönderbrytning men också av att asfalten förlorat sin eftergivlighet genom åldring. Det är en naturlig förändring som påverkas av luftens syre och solens strålning men också av ämnen i miljön. Tillvaratagen asfalt kan emellertid ges nytt liv igen, återvinnas, och användas på nytt som vägbeläggning. Det sker g
Bio-based materials are considered to be an effective alternative to fossil-based materials and are being studied globally. It will be a long journey for the commercialisation of bio-based materials. Apart from waiting for the material technology to be mature, how will the material be rolled out to the market? This is the challenge faced by all material companies. The project is in collaboration
Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. This thesis is a first step towards the realization of CPS in InAs nanowires with crystal-phase defin
De senaste årens volatila marknadsläge har lett till konflikt mellan beställare och entreprenör med avseende på osedvanliga prisökningar och leveransstörningar. Det råder sällan en gemensam bild i projektorganisationen kring hanteringen av dessa vilket kan påverka relationen mellan beställare och entreprenör. Studiens syfte är bidra till en kunskapsutveckling som gynnar aktörerna som påverkats avThe volatile market situation in recent years has led to a conflict between client and contractor with regard to unusual price increases and delivery disruptions. There is rarely a common understanding in the project organization on how to deal with these, which can affect the relationship between the client and the contractor. The aim of the study is to contribute to the development of knowledge
The labor market integration of immigrants in general, and female migrants in particular, remains a central developmental objective for counteracting inequalities within societies across Europe. Previous studies put forth the concept of social capital, the resources linked to an individual's network of social connections, to explain immigrants’ diverging labor market trajectories. Policy-maker
Background: Studies have put spinal bifida which Myelomeningocoel (MMC) is a form at 6.1 per 10,000 births in Sweden. Other evaluations have pointed that disabilities could pose a burden on families despite the social net available within the Swedish society. It has been reported that depression, musculoskeletal disorders, and frequent health care visits are often likely to be reported in parents
För att utöka biogasproduktionen i Västra Götalandsregionen (VGR) kan restströmmar från jordbrukssektorn fungera som en storskalig leverantör av biomassa. Produktionen av biogas minskar beroendet av fossila bränslen och rötresten som bildas kan också återföras till jordbrukssektorn, vilket skapar ett slutet kretslopp. I detta examensarbete granskades utökningen genom en kartläggning av biogasproduTo expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. The expansion was assessed in this thesis by the investigation of
Detta examensarbete har skrivits i sammarbete med ett företag i södra Sverige. Målet har varit att utvärdera ett befintligt industridesign-förslag, undersöka vilka industraliserbara lösningar som finns tillgänglig på marknaden idag, och generera ett nytt designförslag som kan implementeras under en kortare tidsperiod. Målet med designförslaget har varit att ta fram en design som har en ny look-andThis master thesis has been written in collaboration with a large company in southern Sweden. The goal has been to evaluate a current industrial design proposal, look at the current technology available on the market, and then generate a new proposal that can be implemented in a short period of time. The goal with the design was to generate a design the has a new look-and-feel, while still fitting
This master thesis project was performed in collaboration with an agricultural cooperative Lantmännen Oats AB, who has developed a dry protein powder concentrate PrOatein™. The powder consists of oat proteins, dextrins, lipids and β-glucans. The aim of the thesis was to investigate the powder’s functionality in a liquid emulsion and see if it can be improved by pre-treating it with thermal heating
This master thesis, executed in collaboration with Opticept Technologies, has the purpose of developing a machine concept that enables the treatment of leafy products with Pulsed Electric Fields (PEF). PEF is an emerging technology within the food industry that works by changing the cell membrane structure of food products by exposing them to high-voltage electric fields. It can be used to improve
Companies have increasingly launched brand extensions in recent years while building on the credibility of the parent brand. Early brand extension research led to conservative statements about brand extensions and most research around them focuses on success factors from a quantitative perspective. Far less research addresses the brand meaning and the role of brand relationships in the context of
Studien kretsar kring unga vuxnas relationer till sociala medier ur deras eget perspektiv. Fokus fästs på vilka tankar och känslor som unga vuxna förknippar med särskilda digitala plattformar, såsom Facebook, Instagram, Snapchat och TikTok, i syfte att undersöka hur de själva tycker att de påverkas – antingen positivt eller negativt – av dessa sociala medier. Vidare innefattar studien utgångspunkt
Att det finns ett behov av ett nytt transportsystem som ej bygger på (den fossildrivna) bilen är nästintill konsensus i större delen av den moderna världen idag. Det är också konsensus att cykeln kommer att vara en viktig del i denna omställning. Ett problem med vår samtids insatser för att främja cykling är dock att de sker i en kontext präglad av bilens hegenomi. Utformning av ny infrastruktur o
