In this master thesis we have studied the possibilities of implementing and controlling the speed of a brushless DC motor in an hydraulic application developed by BorgWarner TorqTransfer Systems AB. The hydraulic application is a coupling that give vehicles intelligent all-wheel drive. Today, the hydraulic application uses hydraulic pressure controlled by an ordinary DC motor to produce the all-w
One of the leading challenges presented in 21st century for packaging industry is to address the growing environmental problems related to non-renewable flexible packaging. This leads to new growing interest in bio-based materials, among them cellulose nanocrystals (CNCs), which have already shown good performance in improving anti-fog and oxygen & water vapor barrier properties when applied t
My paper focuses on the experiences of China’s female sex workers. In particular, this paper focuses on the workers’ lives before joining the sex industry. The research question that is posed asks: “What makes Chinese women become sex workers (i.e., prostitutes)?” Online interviews as well as online personal statements, along with previous research from articles and books are used to study prostit
Islamic finance has been growing tremendously for the past years. On the other hand, the understanding of it, is still limited compared to the conventional finance. Claims that Islamic finance is more resistant to crisis compared to the conventional finance is analysed in this thesis through the comparison between Sukuk and bond financing. There are two aims of this thesis. The first aim is to stu
Det har blivit allt vanligare med användandet av både tidsbegränsade anställningar och inhyrning av personal från bemanningsföretag på svensk arbetsmarknad (LO 2014:2-3). Med anledning av det vill jag ta reda på hur arbetsgivarna ser på detta. Syftet med uppsatsen är att undersöka hur arbetsgivarna resonerar kring frågor som rör tim- och visstidsanställningar, bemanningsföretag samt lagen om anstä
The load transfer and redistribution phenomenon that occurs through the mobilization of shear stresses in response to relative displacements in granular materials, such as soils, is attributed to the arching effect. The arching effect has a great influence on the behaviour of soils and plays an important role in predicting earth pressure in granular backfills of limited extent, confined by unyield
Med elasticitetsteori kan man inte beskriva hur en statiskt obestämd konstruktion där materialet kan plasticeras går till brott. Enligt elasticitetsteori och ett antagande om ett sprött brott vid en viss spänning går en konstruktion till brott så fort denna spänning uppnås i det högst belastade snittet. Det som egentligen sker är att materialet plasticeras vilket leder till en momentomlagring. KonUsing theory of elasticity it is not possible to describe exactly how a statically indeterminate structure collapses. Theory of elasticity is often combined with an assumption of breakage at a certain level of stress, this meaning that a structure will break as soon as this level of stress is reached in the most heavily loaded section. A plastic hinge will occur followed by a changed distribution
Induced subgraph detection is a widely studied set of problems in theoretical computer science, with applications in e.g. social networks, molecular biology and other domains that use graph representations. Our focus lies on practical comparison of some well-known deterministic algorithms to recent Monte Carlo algorithms for detecting subgraphs on three and four vertices. For algorithms that invol
Litteraturstudien visar att hämndporr är på väg att bli en trend bland dagens ungdomar, att hämnas på en före detta partner genom att offentliggöra intima bilder eller filmer av personen utan dennes samtycke har blivit ett allt större problem. Detta kan medföra en mängd olika negativa konsekvenser för offren såsom att förlora jobbet, utsättas för stalkning, depression, ångest och i en del fall äve
Johnson Matthey Formox är ett företag som designar och säljer fabriker för produktion av kemikalien formaldehyd. Företaget tillverkar även katalysatorer för detta ändamål. För att erbjuda en bra och konkurrenskraftig produkt till sina kunder är företaget måna om att processen skall vara effektiv och framförallt kostnadseffektiv. En del i detta är att kartlägga hur vatten påverkar produktionen av fThis diploma work has been performed in collaboration with Johnson Matthey, a company supplying catalysts and technologies, such as formaldehyde plants and catalysts. The aim of the master thesis project was to investigate if and how water impacts the partial oxidation of methanol to formaldehyde over a FeMo-catalyst. The investigation covers how water affects the selectivity to the main product a
This Master Thesis in Sociology of Law is a case study, which explores the corporate social responsibility reporting practices of companies located in two different Member States of the European Union. More specifically, the research reviews how the implementation of a European Union Directive is going to affect the corporate social responsibility reporting practices of these companies. Through co
The title of this bachelor thesis is: ”The turban - A study of the Oriental fashion and the turban´s process of deorientalizing”. The Orient has fascinated Westerners for a long time, especially within the fashion industry. Ever since the first voyages of discovery, there has been a constant exchange of arts and culture between East and West. Oriental fashion can be defined as a fashion that draws
Studies of decision-making have shown that attitudes can be influenced by choices. One way in which to study these types of attitude changes can be through the choice blindness paradigm. Choice blindness is the well documented finding that people may both fail to notice that the outcome of a choice does not correspond to what was intended, and at the same time construct coherent arguments in suppo
The aim of this research was to gain a more nuanced picture of sustainability in furniture retail by investigating how it is handled in a furniture retail chain. The chosen method was setting up a case study on MIO AB, the central organization of a Swedish franchise chain, where data was collected using interviews and observations. The theoretical framework focused on sustainability aspects in the
Syftet med uppsatsen är att undersöka hur samproduktion av en omprofilering sker inom varumärkesforum på sociala medier.Uppsatsen grundar sig i en kvalitativ forskningsstil och använder sig av en netnografisk studie av fallföretaget Oatlys varumärkesforum på sociala medier i kombination med en semistrukturerad telefonintervju med Sara Hansson, ansvarig för sociala medier på fallföretaget Oatly.

Operators in DCS environments control and supervise the process with the help of Human-Machine Interfaces (HMI). The operators are usually stationary (or at least semi-stationary) because the HMI is stationary. The purpose of this bachelor’s thesis is to explore the prospects of using mobile devices, primarily touchpads, in Distributed Control System (DCS) surroundings. This includes (but is not l
This bachelor thesis project was carried out at Schneider Electric in Helsingborg, where the objective was to use an old robot with three linear axes. The engines were replaced and control cabinets with their latest products were built together to work and to become a complete unit. The complete unit was mounted on a cage which will be used by Schneider Electric for marketing. The Project is based
The condition of the Swedish railway has been frequently discussed, mainly during recent years. Lack of maintenance and budgetary allocation are words that constantly arise. During the winter the topic is notably higher, especially because of the media that regularly reports about cancelled and delayed train departures. This thesis will plunge into the difficulties that the railway sector will fac
