Tröger’s base molecule has a unique V-shaped cavity and a chiral structure. These molecules can be fused together in a linear fashion to create either tubular structure or zigzag structure. Different fields can be benefited from the applications of these molecules. Previous studies carried out in the Wärnmark group led to 30-step synthesis route to get a linearly fused heptakis-Tröger’s Base anal
Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. Based on temperature- and wheel-speed measurements, a mathematical model of
Största delen av det svenska vägnätet består idag av belagd väg. Med det i åtanke så krävs det därför att vägarna vid sin anläggning respektive när underhållsåtgärd sker blivit väl dimensionerade samt blivit korrekt utförda. Under en tid i Sverige har Trafikverket med sitt dokument TRVK väg numera TRVINFRA styrt hur de statliga vägarna skall dimensioneras med sina tre dimensioneringsklasser. I dirThe largest part of the Swedish state roads are today paved. With this in mind it is therefore demanded when a road in question is constructed respectively when a maintenance measure is taken place that the dimensioning of the road from the start was done properly. Since a while back in Sweden it has been upon the Swedish Transport Administration to regulate with their document “TRVK Väg”, now TRV
This research paper investigates notions and values that composers have regard to artificial intelligence and composition. The research is based on a survey that was sent to students and teachers of composition at Malmö Academy of Music. A total of 32 emails were sent, of which 15 were answered. 12 of the informants were students and 3 were teachers. Of the 32 individuals surveyed, the number of t
Power system infrastructure has been facing many challenges when it comes to harmonics distortion, and power electronic devices are no exception considering their wide usage in the system. In this thesis the focus is on the impact of these system harmonics on the electrical motors which are vastly used in industry for different applications. Motors usually come with a softstarter, and are connecte
Syfte: Syftet med studien är att undersöka kulturell påverkan av kreativa inslag i standardiserad reklam. Med studien vill författarna bidra marknadsföringsbyråer med en utökad förståelse för hur den kultur som är associerad med landet inom vilken byrån agerar kan ha en omedveten påverkan på produktionen av reklamfilm. Metod: I studien utför författarna en semiotisk innehållsanalys av standardiPurpose: The purpose of the study is to investigate the impact that a country's culture has on the use of creative elements in standardized advertising. Thus contributing to the understanding of how the culture associated with a country in which a marketing agency operates can influence their production of commercials. Methodology: The study is a content analysis of standardized commercials p
Climate change is the greatest challenge of our time. Despite efforts to reduce greenhouse gas (GHG), the emissions contribution from global aviation is set to increase. Electric aviation has emerged as an alternative which could form part of the solution. Sweden, which is on the path to carbon neutrality and has a long history in aviation, could contribute to the global efforts in mitigating clim
Unfriending someone on Facebook is a phenomena which can be seen in many different contexts and unfriending someone for political reasons can create obstacles for political conversations as it can increase polarization in society. In recent years there has been a tendency of unfriending individuals that express sympathies for the political party Swedish Democrats (SD) which can be perceived as sti
The contribution of greenhouse gas emissions in the production of construction materials has sparked a new interest and recent changes in building regulations regarding the use of renewables like wood as the main component in load-bearing elements. Recent regulation changes focus on allowing taller timber structures which bides the question of how to adequately maintain an acceptable level of f
Less than a decade ago, Swedish law demanded that a person who wanted to change their legal gender had to be without any ability to reproduce. This demand led to many trans people being forcibly sterilized. Even though the demand is now removed from law, lingering effects continues to affect trans people in their reproductive journey. This study examines barriers faced by trans people in three sta
Syfte: Undersöka kapitalstrukturen hos företag inom IT- och teknologibranschen i hela världen samt vilka faktorer som påverkar kapitalstrukturen hos dessa företag. Vidare testas hur väl etablerade teorier förklarar valet av kapitalstruktur samt genomförs en jämförelse med tillverkningsindustrin. Metod: En kvantitativ studie med en deduktiv ansat genomförs. Studien bygger på sekundärdata och analysPurpose: Investigate the capital structure of companies in the IT and technology industry worldwide and determine which factors affect their capital structure. Furthermore, a comparison with the manufacturing industry is conducted. Methodology: A quantitative study using a deductive approach has been conducted. The study is based on secondary data which has been analyzed through a regression analy
Denna studie har utforskat kvällspress (Expressen och Aftonbladet) och myndigheters (Folkhälsomyndigheten och Regeringen) strategiska kommunikation under coronapandemins inledande fas i Sverige och analyserat detta dels baserat på kriskommunikationsteori, dels dagordningsteori med gestaltningsteori och teorin om den retoriska arenan. För att kunna genomföra en Retorisk Arena-analys på materialet iThis study has explored the strategic communication of The Public Health Agency of Sweden and the Swedish Government compared to tabloid press of Sweden (Expressen, Aftonbladet) during the initial phase of the coronapandemic in Sweden and analyzed it based on crisis communications theory, partly agenda-setting-theory including framing theory and the theory of the Rhetorical Arena. In order to comp
Wheat bran is a by-product from the production of wheat flour. Nowadays wheat bran is mostly used as feed for animals, in the food and baking industry or it is simply burned in open air. However, wheat bran could be used in biorefineries for production of value-added products such as bioplastics, biofuels and chemicals as a substitute for fossil feedstocks as petroleum. Since wheat bran is an agri
Over the last few years, there has been a proliferation of different kinds of movements across the globe as citizens agitate for economic, socio-political and environmental change. In the Democratic Republic of Congo (DRC), where the country has been involved in a series of wars, attention has rather been eschewed towards the rape and sexual violence of women and girls. Using post-colonialism and
Vi människor, och djur i allmänhet, lär oss enormt mycket från att bara interagera med våra omgivningingar. Vi samlar ständigt in information om hur våra handlingar påverkar omgivningen, och justerar vårat beteende så att vi bättre uppfyller våra mål. En gren inom maskininlärning, som kallas förstärkningsinlärning, är ett grupp metoder som beskriver en agent som kan lära sig att uppnå mål från erThe success of Reinforcement Learning (RL) has mostly been in artificial domains, with only some successful real-world applications. One of the reasons being that most real-world domains fail to satisfy a set of assumptions of RL theory. In the past years, a popular way to gauge the performance of RL agents has been through a suite of Atari 2600 games. This suite has been used to benchmark the pr
Swedish exophoric demonstratives have often been seen as words that encode distance-based concepts. Based on the studies of demonstrative systems of several other languages the view of demonstratives as distance-oriented has recently been put into question. Thus, this study aims to investigate the spatiality involved in the semantics of demonstratives. Specifically, the study explores Swedish two-
Language contact poses many questions in regards to language change, one of which is the question of whether some features are more easily transferable between languages than others. Previous research has mainly focused on either areal features in so-called Sprachbunds in large quantitative studies, or single language situations. The present study attempts to bridge the gap between these two diffe
Vision is often considered to top the hierarchy of the senses, reflected for example in the high relative frequency of vision verbs, in comparison to other perception verbs. Results from some previous studies, however, have shown that there is greater cross-linguistic variation concerning perception language than previously thought, emphasising other sense modalities than vision. This thesis condu
Constructed wetlands (CWs) have been applied for several years in the removal process pollutants from secondary treatment plants and stormwater. In this paper, the Variable Residence Time (VART) model for solute transport in streams was extended to simulate the BOD removal process in free water surface flow constructed wetlands (FWS CWs). The double layer concept of the basic VART model was extend
