The nonlinear Schrödinger equation is a partial differential equation which appears as a model in several branches of physics, including Bose-Einstein condensation and hydrodynamics. In this thesis, we investigate a particular class of solutions, namely periodic standing waves. We derive explicit formulas for the solutions using elliptic functions and study their variational properties. The standi
No suitable contrast agent for bowel diagnostics exists on the market today. A solution may be a new potential food-based contrast agent called Lumentin, which is based on foaming egg white. To gain new knowledge about the contrast agent, the objectives of this project were to study the physiochemical properties of different egg white powders (A-F) that can be used to prepare Lumentin and their fo
År 1997 byggdes en havsvall i Isahaya bukten i Ariake havet, Japan, för att återta land för lantbruk och översvämningskontroll. Den här studien undersöker hur havsvallen har påverkat den barokliniska strukturen i Ariake havet och bildandet av hypoxiskt vatten i Ariake havet genom att fokusera på påverkan från förflyttningen av utflödet av färskvatten, den tidsmässiga förändringen för utflödet av fIn 1997 the Isahaya Sea Dike was built in the head of Isahaya Bay which is a branch of the Ariake Sea, Japan, with the aim of reclaiming land for agriculture and flood control. This study examines how the Isahaya Sea Dike has affected the baroclinic structure and development of hypoxic waters in the Ariake Sea by focusing on the spatial change of freshwater discharge, the temporal change of freshw
The decision by the United Kingdom to exit the European Union will have significant repercussions for the global economy. The consequences of Brexit have been studied through different perspectives and methods, however there is a lack in the literature in using a regional perspective. This study thus aims to fill this gap by estimating the industrial impact of Brexit on the United Kingdom through
The outcomes of flood management are uncertain since climate change and urban densification are expected to result in higher amounts of surface runoff, and both these changes are subject to uncertainty. When uncertainty is deep, there is a need for strategies to treat uncertainty, e.g. taking the limitations of quantification by probabilities into account, and to guide decisions to be robust to un
Evidence from the U.S equity market shows that the cyclically adjusted price to earnings ratio (CAPE) is a strong predictor of future long-horizon stock returns. This paper focuses attention on the Swedish equity market to see whether the CAPE-ratio is applicable to the Swedish market. Furthermore, to see whether a set of secondary explanatory variables may strengthen the predictive power addition
This thesis researches territorial stigmatisation in the context of urban renewal and state-led gentrification in Gothenburg. Focusing on post-industrial transformation in the geographical area of Hisingen, the thesis reaffirms the need for critical analyses of urban renewal. The thesis explores discourses about the district of Hisingen using Norman Fairclough’s model for critical discourse analys
I denna uppsats appliceras Fama-Frenchs femfaktormodell på den svenska aktiemarknaden och jag undersöker om det går att ge stöd för att en utökning med en eller två faktorer till Fama-Frenchs trefaktormodell förbättrar förklaringsförmågan till variationen i aktieavkastning. Fama & French (1993) visar att en modell bestående av tre faktorer - marknadsfaktorn, storleksfaktorn och värdefaktorn -
Syftet med denna studie var att explorativt undersöka upplevelser av dansrörelseterapi med mindfulness som intervention för människor med långvarig smärta. Interventionen genomfördes som en sexveckors kurs med träffar på veckobasis. Utöver det fick deltagarna en CD-skiva med mindfulnessmeditationer för hemmaträning. Sessionerna på ca 2,5 timmar var uppbyggda på samma sätt varje gång; de började ocThe aim of this study was to exploratory examine experiences of dance movement therapy with mindfulness as an intervention for individuals with longstanding pain. The intervention was conducted as a six-week course with sessions once a week. Besides that, the participants received a CD-record with mindfulness meditations for home training. The sessions lasted 2,5 hours and was composed in the same
En undersökning av tre Lovecraft noveller utifrån Tzvetan Todorovs teorier kring "det fantastiska".
This thesis focuses on the growing demand for traceability in continuous processes within the food and beverage industries. Three market-leading companies have contributed valuable input to this thesis to identify common interests. Using modern technology, a demo application has been developed to show the power in gathering several data sources and traceability into one graphical user interface, G
The purpose of this paper is to investigate whether macroeconomic uncertainty has a negative effect on Nordic banks’ loan supply. To test this a model is defined with a gross loans/total asset ratio as the dependent variable and a proxy for macroeconomic uncertainty is used as the explanatory variable. A crucial step is the definition of macroeconomic uncertainty. In this paper five different meas
Cardiac magnetic resonance is widely used to non-invasive image the heart, for both clinical and research purposes. Segmenting different parts of the heart provides important diagnostic information. Performing this task manually is time-consuming and operator dependent, hence it would be beneficial to automate this process. The aim of this thesis is to implement an algorithm to segment the right v
Krein strings appear in the study of the motion of a vibrating string where an irregular density is allowed. This thesis presents the theory from the perspective of integral equations and operator theory. It will be shown that each Krein string gives rise to a unique Stieltjes function, by utilizing the compactness of the resolvent operators for short strings and then approximating any long string
Detta är en uppsats i retorik som diskuterar vilken försvarsstrategi Johaug väljer och hur den fungerar, då hon bli anklagad för användning av det dopingklassade ämnet Clostebol. Uppsatsen är till största del baserad på statusläran för att hitta oenighet i det nämnda fallet och för att se vilket försvar Johaug för och om det vidhålls under utredningen av doping. Analysen av denna uppsats har visat
The purpose of this essay is to examine how two nonfiction books for children in the category sexual education from Sweden portrays gender and sexuality. Norman Fairclough’s critical discourse analysis is the method of choice, where the nonfiction books are seen as part of a discourse in which language is not neutral. The analysis is based on Judith Butler’s theories on the heterosexual matrix and
Majorana bound states can be created at the ends of semiconducting nanowires using a combination of proximity-induced superconductivity, spin-orbit coupling and a magnetic eld. By adding a Josephson junction to this nanowire, four Majorana bound states can exist at the same time in the system. In this thesis I aim to examine the impact that the barrier in Josephson junctions has on the energy stat
Denna studie syftade till att, för tjejer och killar separat, beskriva ungdomars livstillfredsställelse inom aspekterna familj, vänner, boendemiljö, skola och själv och psykisk ohälsa med avseende på depression, ångest och stress samt att undersöka hur dessa aspekter är associerade. En grupp bestående av 121 ungdomar mellan 16 och 19 år i en svensk kommun besvarade en webenkät. Resultaten visade pThis study aimed to examine relationships of five aspects of life satisfaction (family, friends, neighborhood, school and self) and three aspects of mental health problems (depression, anxiety and stress) among adolescents. An online survey was administered to a sample of 121 adolescents aged 16 to 19 in a Swedish town. The results showed a relatively high degree of life satisfaction in all aspect
