This work aims to study the electron transport in quantum dots defined by wurtzite segments in otherwise zinc-blende InAs nanowires. The electronic circuit consists of the nanowire, the source, drain and the three additional gates. We use the Constant-Interaction model to describe various electronic properties of the single and double parallel quantum dot. We relate the measurement outcomes to the

Social media is a field that is developing quickly. A field that brings both risks and opportunities for companies. It has become especially important for startups since using it requires only a small amount of resources. Even though many startups realize the value potentials with using social media, effective utilization of it still poses a daunting challenge to many of them. Based on a combinati

In this work we have addressed the task of segmentation in skeletal scintigraphy images with deep learning models, where we research different approaches to convert convolutional neural networks designed for classification tasks to powerful pixel wise predictors. We explore different network architectures where two primary research paths have been followed. Firstly, an encoder-decoder architecture

År 2016 presenterades skolverkets strategi för digitaliseringen av skolväsendet. Där fastslås att visionen för gymnasieskolan är att eleverna ska utveckla en digital kompetens och att skolan ska tillvarata digitaliseringens möjligheter. Trots visionerna så är användningen av digitala läromedel låg, i en undersökning från lärarnas riksförbund angav 59 procent av dem tillfrågade lärarna att de använ

Nowadays, China has made great efforts to make international hotspot issues peacefully settled in Asia, Africa, and the Middle East. One challenge China faces on its road to global prominence is how to balance the increasing international responsibility and the established foreign policy principles that have been upheld for decades. The thesis attempts to answer why China sticks to the non-interfe

When experience is insufficient or not present at all, making decisions becomes difficult. Capability assessments are tools to inform decisions in all situations regarding risk management, but the use of them in Sweden is discussed. With experiments made in the microworld MikroRisk, conclusions can be made about the investment patterns induced by a capability assessment under the conditions of bot

In any storage ring or synchrotron based light source one of the most important factors for generating light with desirable properties is the electron beam itself. The dynamics of the beam must be properly characterised and, ideally, adjusted to the desired values for the light source to be able to deliver radiation of the quality which was decided during its design. This thesis is limited to som

Sexualitet har länge varit föremål för kontroll, kategorisering och reglering. I vårt nutida västerländska samhälle har vi lagar som reglerar vilka sexuella handlingar som är acceptabla och vilka som inte är det, och vissa typer av sexualitet är även sjukdomsklassade. De senaste åren har viss form av sex diskuterats intensivt i svenska nyhetsmedier; nämligen pornografi. Diskussionen berör frågor oThe aim of the study is to examine discourse on pornography in Swedish news media. The methodological point of departure is Critical Discourse Analysis, as presented by Fairclough. The empirical material consists of 69 articles, editorials and chronicles publicized in Swedish news media between July 2013 and March 2017. The primary theoretical point of departure of the study is Fairclough’s critic

The world under globalization is moving toward a single market, where national economies are becoming more integrated and interconnected. In this context, over the last decades, the perception of FDI positive spillovers has made developed and developing countries competing to attract foreign investors. This study analyses the determinants of FDI during the globalization process, both theoretically

This thesis is about investigating the feasibility to use convolutional neural networks as a demosaicing approach. Three loss methods and different layer structures have been evaluated as well as changing different parameters and layers in the convolutional neural network to find which changes are beneficial to make a neural network perform demosaicing well. The convolutional neural network has b

Acute myeloid leukemia (AML) is characterized by a differentiation block in the myeloid lineages of the hematopoiesis. After the success of the all-trans retinoic acid (ATRA) differentiation therapy which overcomes this differentiation block for AML subtype acute promyelocytic leukemia, attempts have been made to find similar therapies for the remaining subtypes. Differentiation therapy candidate

Atomur som är baserade på en optisk frekvens är under utveckling. Dessa optiska klockor är i dagsläget så exakta att om de startades vid big bang, så skulle de bara visa en sekund fel idag. Nästa generations kommunikation- och navigeringssystem kommer att dra nytta av noggrannare tidsmätning. I detta examensarbete behandlas två saker som är viktiga för den fortsatta utvecklingen av optiska klockorAn electromagnetic wave propagating through an optical fiber is sensitive to external disturbances, such as mechanical vibrations and temperature and pressure fluctuations, which add phase noise onto the wave. For high-precision frequency-based applications this phase noise has to be removed. By partially reflecting light from the remote end of the fiber back through the fiber, and comparing it to

Drav är en restprodukt från öltillverkning. Varje år lämnar bryggindustrin i Europa efter sig ca 3,4 miljoner ton drav som idag främst går till djurfoder och biogas. Dravet är i själva verket spannmål, främst korn som först blivit mältat för att enzym ska aktiveras, var på det sedan mäskats och lakats för att utvinna så mycket sockerarter som möjligt till vörten. Drav är en väldigt intressant res

This thesis analyses regional industrial concentration and the determinants of industrial location in Sweden during the first half of the twentieth century. First, it is identified how geographical concentration of industry evolved in this country. Second, by estimating an economic geography model, the forces that were behind industrial location are captured. The inclusion of both procedures provi

Social innovation and social entrepreneurship receive rapidly growing attention today, due to the inability of current structures and policies to meet the most pressing social problems facing the world. This has concentrated attention on the significance scaling social impact can have on social change. This thesis adds to the literature on scaling up in social entrepreneurship, where the main focu

Planeters omloppsbanor är, trots att det kanske verkar så på en tidsskalan som ett mänskligt liv, inte oförenderliga. I planetsystem med två eller flera planeter så påverkar planeterna på varandras omloppsbanor med deras gravitation. Planeterna växelverkar med varandra och ett utbyte av energi och rörelsemängdsmoment sker. Rörelsemängdsmoment är motsvarigtheten till rörelsemängd för saker i rotatiDetection of Earth-mass planets on orbits around 1 AU with the radial velocity method has so far not been possible, the Doppler velocity they induce on their host star is too small to be detected. Planetary systems detected with the radial velocity method might then contain undetected Earth-like planets. One such planetary system is HD37605, which contains a star similar to the Sun and two gas gia

HUR SVÅRT ÄR DET ATT TORKA ETT VITT PULVER? Frågan om energieffektivisering är idag ytterst aktuell och då inte minst för företag inom industrin där energianvändningen kan vara väldigt stor. Att minska sin energianvändning sparar inte bara pengar utan även miljön och ger en bättre ”grönare” image. I studien som utfördes tog man fram nyckeltal för utvärdering av en torkprocess samt analyser av prodDue to the act on Energy Audits in Large Enterprises (EKL) that came into effect on the 1st of June in 2014, all larger companies are obligated to perform an energy audit every four years. Parallel to the audit performed at Alufluor AB this more detailed audit of the drying part of their process was carried out. This as the drying part is energy intensive and is responsible for the majority of the

Social entrepreneurship experienced a significant rise in the past two decades. Yet, research on how companies in social entrepreneurship organize their business model is still rare. Therefore, this thesis aims to investigate how these companies combine social and economic value creation. More precisely, it is analysed how they design, organize and innovate their business model. First, a content a

För att de globala utsläppen av CO2 ska minska bör industrier se över sin användning av olja och gas i sina processer och byta det till något som är CO2-neutralt. Om detta ska vara möjligt bör ersättningsbränslet vara förnyelsebart och samtidigt ha liknande förbränningsegenskaper som kan förväntas av olja och gas. Träpulver är ett bränsle som anses ha potential att uppfylla dessa krav. Denna rapTo reduce the global emissions of CO2, industries have to do an overview of their oil and gas usage in their processes and substitute it to something CO2-neutral. To implement this, the new fuel has to be renewable and have similar combustion properties as oil and natural gas. Pulverised wood is a fuel that is believed to fulfill these qualifications. This report is a investigation, based on a l

I projektet undersöker jag hur ett enfamiljshus kan få ytterligare kvalitéer genom att göra dess konstruktion och uppbyggnad synlig. Jag låter konstruktionen vara närvarande i rummet och med hjälp av den skapa rumsliga kvalitéer. Konstruktionens materialitet och tektonik görs närvarande i rummen och ger ett mervärde. Inledningsvis tittade jag på danska villor från 60-talet som innehöll dessa kvaliIn this project, I investigate how a single-family house can get additional qualities by making its constructive and structural components visible. I let the construction be present in the room and from it create spatial qualities. The goal is to do this in a way where the materiality and tectonics of the construction are present in the rooms and give the building additional qualities. Initially I
