Hafnium dioxide (HfO_2) based thin films doped with various dopants (Si, Ge, Al, Gd, Sr, Zr) have been found to exhibit ferroelectricity. These dopants were found to stabilize the III orthorhombic phase in the hafnium oxide based thin films. This characteristic enables and allows various applications ranging from Non-volatile memory, Ferroelectric Field-Effect-Transistors, to Negative Capacitance
Examensarbetet har utvecklat en metod för att estimera den fraktala dimensionen från Transmissions Elektron Mikroskop (TEM) bilder av sot aggregat som skapats med hjälp av en mini-CAST sotgenerator. Det är ett underbestämt problem att estimera den fraktala dimensionen, en 3D egenskap, från 2D bilder. Lösningen är syntetiserade TEM bilder som baserats på projektioner av numeriskt simulerade aggregaIn this master’s thesis a method for estimating the fractal dimension from Transmission Electron Microscope (TEM) images of soot aggregates has been developed, and also applied to TEM images of soot sampled from a mini-CAST soot generator. The problem to estimate the fractal dimension, a 3D property, from a 2D image is undetermined. To solve this, TEM images were synthesised based on projections o
Anxiety disorders and obsessive-compulsive disorder among women in the postpartum period are understudied and their impact upon maternal functioning is poorly understood. There is evidence that individuals with greater levels of psychological flexibility (the ability to persist in valued domains of living despite the presence of negative emotions/thoughts/sensations) and higher levels of social su
Abstract Sedan 70- och 80-talet har det forskats kring manligt och kvinnligt språk, främst genom samtal. Forskare har kommit fram till att män och kvinnor har olika samtalsstilar och att olika stereotyper finns rådande manligt och kvinnligt språk. Syftena med den här studien är att undersöka podcastlyssnares attityder till språket i podcaster i allmänhet och i synnerhet manligt och kvinnligt språk
This work presents the notion of free groups and the definition of a group using generators and relations. We use the Todd-Coxeter Algorithm in order to solve the coset enumeration problem for the finitely presented groups: $D_4,\, A_4,\, A_5,\, S_3,\, S_4,\, S_5,\, PSL_2(7),\, PSL_2(9)$. Then we use these presentations in order to prove the exceptional isomorphisms $A_5\cong PSL_2(5) \cong SL_2(4
Ungdomsspråk har studerats sedan senare 1900-tal. Ulla-Britt Kotsinas (1984) och Lars Gunnar Andersson (1985) finns bland de forskare som beskriver vilka funktioner som ungdomsspråket har bland ungdomar, bland annat skriver de om hur slang och svordomar kan användas som grupptillhörigehetsmarkörer. Slang, svordomar och ungdomsspråket generellt har en tendens att förändras och förnyas vilket gör de
In last decade, the lighting industry significantly changed with the development of light emitting diodes (LEDs) and their corresponding penetration of the market. The new technology increases energy efficiency and longevity compared to other types of lamps. As a result, LEDs can improve the sustainability performance of cities and towns, contributing to the mitigation of climate change and cuttin
Vad tänker du på när du hör ordet solprognos? För vissa är det viktigt i planeringen av semestern, andra kanske för att skydda sig mot farlig UV-strålning. Vad många inte vet är att solprognoser är en viktig komponent i vårt energisamhälle där förnyelsebara energikällor som solkraft och vindkraft ökar kraftigt runt om i världen. Att göra träffsäkra prognoser för inkommande solstrålning har dock viSolar radiation is affected in a variety of different ways through the atmosphere and on its way down to the Earth’s surface. Clouds are the main factor in this attenuation of solar radiation, but aerosols, ozone and other different gases have a significant impact too. Understanding these processes is fundamental to solar forecasting. However, the atmosphere is constantly changing, which makes for
This master thesis contributed to a project financed by the Swedish Energy Agency and managed by the housing company Eksta AB in collaboration with the consulting Company WSP. The main aim of this master thesis was to perform a theoretical optimization on the usage of own used solar electricity by transferring the surplus PV between buildings in a demonstration area in a DC-microgrid. To achieve th
Delay discounting and time perspective, two similar but not identical constructs, are associated with consequential choices in the financial and health domain. Six gaps in the literature comparing the predictive validity of delay discounting and time perspective are identified and their importance for longitudinal studies is discussed. The most extensive comparison of consequential choices in the
Landscape fragmentation and decreasing habitat areas poses a threat to biodiversity worldwide. Green infrastructure has developed as a conservation approach promoting habitat connectivity on a landscape scale. However, green infrastructure is much more than a network of natural structures and elements enabling species movement. It represents a new mode in environmental protection policy, addressin
Samarbete i grupp påverkas av kompositionen av medlemmarnas personlighetsdrag. Syftet med denna studie var således att undersöka hur skillnad av personlighetsdrag inom Big Five-teorin korrelerade med uppgiftskonflikt, gruppsammanhållning och kommunikation. Vidare undersökte studien hur skillnaden påverkade uppsatsgruppers prestation. De personlighetsdrag som undersöktes var öppenhet, vänlighet och
Deep reinforcement learning has been shown to be able to solve tasks without prior knowledge of thedynamics of the problems. In this thesis the applicability of reinforcement learning on the problem ofproduction planing is evaluated. Experiments are performed in order to reveal strengths and weak-nesses of the theory currently available. Reinforcement learning shows great potential but currentlyon
Uppsatsen syftar till att redogöra för och analysera de konsekvenser som uppstått för fåmansföretagare och skattesystemet till följd av slopandet av stoppreglerna år 2000. Utmärkande för fåmansföretag är att bestämmanderätten endast utövas av ett fåtal ägare. För att förhindra att intressegemenskapen mellan företaget och delägarna används för att skapa skattelättnader infördes en särreglering förThis essay is aiming to explain and analyse the consequences that occurred to the owners of closely held companies due to the abolishment of the special tax legislation in 2000. The right to decide is gathered within a few owners in closely held companies. In order to prevent that this enables advantages in taxation a special regulation was introduced for closely held companies in 1976. The speci
This study examines the Refugees Welcome Movement campaign in Malmö between the period September 2015 and June 2016. The purpose of this study derives from the identification of a knowledge gap of descriptive, as well as analytical accounts that conceptualises the many and long withstanding occurrences of collective action within Social movement theory. This study aims therefore to tackle this kno
This study aims to investigate the relationship of a campaign video aimed to prevent stigmatisation of mental illness, and the possible risk of reproducing a stigmatising portrayal in using humor to convey the campaigns message. The focus of this study is the anti stigma campaign video called the Stand Up Kid, which is viewable on Youtube. The study uses a method of textual analysis, in combinatio
Av försäkringsavtalslagen, FAL, 6 kap. 1 § framgår att bara lagliga intressen kan försäkras. Den här uppsatsen syftar till att genom en rättsdogmatisk metod utreda vilken innebörd begreppet lagligt intresse har. Fokus ligger på att undersöka hur administrativa sanktionsavgifter enligt EU:s nya dataskyddsförordning bör behandlas i svensk försäkringsrätt och om det är möjligt att försäkra sig mot riAccording to the Swedish Insurance Contracts Act (FAL) 6 chapter 1 §, only legal interests can be insured. By using a legal dogmatic method, this essay seeks to examine the significance of the term legal interest. This paper is especially focused on investigating how administrative fines, pursuant to the new EU General Data Protection Regulation (GDPR), should be treated in Swedish insurance law,
The accuracy and portability of depth cameras have increased by a lot in recent years, which allows for advanced 3D scanning of the environment for robotic applications. In this thesis we have developed a system that uses a depth camera mounted on a robot arm to identify and localize arbitrary objects, and give hints on how to move the camera to get better localization results. The system works by
The essay entitled Gösta Adrian-Nilsson in the European Modernistic Power Field. 1913 – 1921, takes its starting point in the city of Berlin in 1912 when Gösta Adrian-Nilsson (GAN) meets the elite of the modern art world for the first time. The descriptive narrative strives to provide insight into how this movement influenced his art as well as his views on Religion and Philosophy. In so doing, a
