In recent years, Deep Learning has proven to be an outstanding tool in the field of computer vision showing promising results in different fields such as the analysis of medical images, obstacle detection for self-driving cars, automatic image caption generation, etc. In the case of Archaeology, the adoption of these methods in the detection of archaeological structures from aerial images has been

This thesis has investigated the potential benefits of using transfer learning when training convolu- tional neural networks for the task of autonomously driving a car. Three transfer learning networks were trained and compared with a conventionally trained convolutional neural network. The first conclusion is that training, as expected, is considerably quicker when using transfer learning. More s

As design students who are about to graduate, we asked ourselves what it means to enter the professional life as a designer. We wanted to investigate how a young designer is able to make a living within the design profession. Additionally, we explored how we can include Northern European industrial manufacturing into our research and design process to learn more about mass production and its poten

I den här studien karakteriseras fenomenet anaerob korrosion utifrån både litteraturstudier om korrosionsprocesser och korrosionsprodukter samt genom undersökning av fältprover från betongkonstruktioner i salthaltiga undervattensmiljöer i södra Sverige. Anaerob korrosion av armering i vattenmättad betong är ett omfattande men hittills relativt ouppmärksammat problem. Detta fenomen kan leda till alIn this study, the phenomenon of black corrosion is characterized by both literature studies on corrosion processes and corrosion products, and by analyzing field samples from saline subaqueous concrete structures in southern Sweden. Anaerobic corrosion of reinforcement in water-saturated concrete is an extensive but yet relatively unnoticed problem. This phenomenon can lead to serious damages tha

The evolution of World Wide Web (WWW) into semantic web is happening with the aid of standards like Resource Description Framework (RDF), SPARQL and a few others from World Wide Web Consortium (W3C). Over the years, semantic data management technologies have been introduced as software platforms commonly known as RDF stores. Lately these RDF stores have been tested for processing and maintenance o

A model of the Swedish power plant Mälardalen Energi, developed by Solvina AB was simulated in Dymola with different types of control strategies in order to evaluate if they could improve the operational flexibility of the plant and, thus, its ability to deliver frequency control to the Swedish power grid. Several different control strategies and process modifications were tested and compared to p

Centrala myndigheters risk- och sårbarhetsanalyser (RSA) som underlag för nationell riskbild- Nationell bild av samhällsviktiga verksamheter och beroenden Att genomföra risk- och sårbarhetsanalyser är viktigt för att skapa en förmåga att förebygga och hantera kriser och olyckor. För att fatta strategiska beslut behöver MSB en nationell riskbild av samhället vilket de bl.a. får genom nationell risThe National Risk and Capability Assessment (NRCA) is used by the Swedish Civil Contingencies Agency (MSB) to decide to develop annual strategic plans. NRCA is carried out by dedicated experts in workshops and interviews with other actors’ representatives, etc. An alternative to this, could have been that the NRCA is performed based on risk and vulnerability assessments (RVAs) conducted by the Swe

Gynna pollinerande insekter i Ängelholms grönområden Ängelholms kommun vill förbättra förutsättningarna för pollinerande insekter i sina grönområden i staden. För att kartlägga förekomsten av humlor, solitärbin och blomflugor har inventeringar gjorts på ett antal platser. För att gynna pollinatörerna har förslag tagits fram på hur man kan öka mängden blommor genom att omvandla gräsmattor till merThe municipality of Ängelholm requested information on how to improve their urban green areas for pollinators. To find out the current status of pollinators, bumblebees, other bees and hoverflies, and to identify the key determinants of their diversity, two types of inventories were made during 2018, field observations and collection with pan traps. 14 sites in central Ängelholm were chosen based

Elevation models are important in many applications in Geographical Information System (GIS), both when applying environmental analyses and in urban planning studies. The production of elevation models has been a difficult and expensive task using traditional surveying techniques. Remote sensing methods for producing digital elevation models have solved the difficult part of the task, which consis

When designing a building one must consider safety aspects. One such aspect is that in the case of an emergency people should be able to efficiently evacuate the building. In this paper we investigate how the width-profile of a corridor leading to an exit might affect the efficiency of evacuation. We model the dynamics of crowds using a continuum model, leading to a one-dimensional non-linear hype

The electricity sector is in the beginning of a large shift from centralized dispatchable production to distributed variable production. With this necessary change, new challenges arise. One crucial challenge is related to upholding the system balance in the power grid. In this master thesis, a Battery Energy Storage System (BESS) has been implemented in an HVDC-system with large amounts of Wind P

Moderaternas förslag om bidragstak syftar till att öka de ekonomiska incitamenten för hel- och deltidsarbete i gruppen av bidragstagare med arbetsmarknadsrelaterade försörjningshinder och högt ekonomiskt bistånd. Detta arbete är en typfallsstudie vilken behandlar förändringen i ekonomiska incitament vid införande av bidragstak. Förslagets potentiella påverkan studeras utifrån hur många hushåll som

Hur ärvs blomdoft? Att lukta gott är inte bara viktigt för oss människor. I växternas värld är doft, eller de kemiska doftsignalerna, livsviktigt för att kunna locka till sig pollinatörer eller avskräcka fiender. Vi vet redan mycket om hur insekter reagerar på kemiska signaler från växter och hur doft varierar mellan olika växtarter, men fortfarande väldigt lite om hur blomdoft ärvs inom växtpopuOne of the main challenges in evolutionary ecology is to identify the factors and agents that drive diversification. Two of the most diverse groups of organisms on earth are plants and insects, and evidence strongly suggests that the diversification of both groups is driven by the interactions between them. One fruitful way for understanding how these interactions evolve and diversify is to identi

Framtiden för verktyg på bibliotek Ett sätt att minska vår belastning på miljön är att dela saker med varandra. Att kunna låna verktyg och andra prylar på biblioteken - är det ett bra sätt att få fler att dela? Många säger sig vilja dela saker med andra men det är inte lika många som faktiskt gör det. Många av de initiativ för delande som finns idag bygger på delande mellan främlingar, men de flThe sharing of goods and services has a lot of potential in tackling the environmental consequences of consumption. Studies indicate that public lending has advantages over private individuals lending each other necessities. It is therefore important to investigate how public lending can be organised most efficiently. Some Swedish libraries provide tools and other things that are not typically ass
