The purpose with this project was to create future self-service points for Skånetrafiken. The ticket machines that are in use today are difficult to interact with and excluding to people who are sight impaired or uses a wheelchair. Since Skånetrafiken are going to implement new self-service solutions in 2019 they want suggestions on how it could be designed. We thought that this project was an exc
One way of reducing environmental pollution is to reduce our dependence on fossil fuels by replacing them with solar radiation (Rs), which is one of the main sources of clean and renewable energy. In this study, daily Rs values at seven meteorological stations in Iran (Ahvaz, Isfahan, Kermanshah, Mashhad, Bandar Abbas, Kerman and Tabriz) over 2010-2019 were estimated using empirical models, suppor
This dissertation analyzes and evaluates several major productions by Danish philosopher and theologian Søren Kierkegaard (1813–1855). It focuses on three works Kierkegaard authored under pseudonyms – Either / Or (1843), Fear and Trembling (1843), and Philosophical Fragments (1844) – and the non-pseudonymously authored Works of Love (1847). The dissertation argues that for Kierkegaard, Christian f
This master thesis investigates material characterization by reflection and transmission of electromagnetic waves in the 40-60 GHz band (millimeter-wave spectrum) for different materials. The free-space measurement method is a fast, efficient and non-destructive way of examining a material and is being researched by both academics and industries. The theory of how electromagnetic waves interact w
The future begins at school – municipal differences regarding education for under-aged EU migrants. The number of exposed EU-migrants in Sweden is growing, and so is the number of under-aged EU-migrants who are travelling with their parents. Many of these belong to the Roma minority in countries such as Bulgaria and Romania. The aim of this study is to examine municipal differences in offering ed
An initial model in the crystallographic structure determination process, usually contains many errors. To produce an accurate model, one must carry out several cycles of crystallographic refinement. Because of the limited resolution typically obtained for biomolecules, the experimental data are usually supplemented by some sort of chemical information, typically in the form of a molecular-mechani
Presented to 42 schizophrenic patients and 19 normals, by means of a percept-genetic technique, two motifs of mother and infant in close interaction (feeding and nursing) . The motifs were tagged, by subliminal presentation, with aggressive resp. "healing" sentences, in a balanced design. No effects of this tagging were discernible. A cluster-analysis (Ward s method) of the material yielded 4 fair
This thesis concerns the numerical simulations and modelling of the flow structure and scalar transport in stirred reactors. For this Large Eddy Simulations (LES) have been used. The flow situation in a stirred reactor includes several flow phenomena that are not well predicted by "standard" two-equation models, e.g. swirl, stagnation points and anisotropic turbulence. Also, using LES one can obta
Popular Abstract in Swedish Bildundervisningen i grundskolans tidigare år uppfyller inte de i Sverige uppsatta målen. De nationella utvärderingarna (NU 89) och (NU92) bekräftar detta. Lärarna säger att de saknar ämneskunskaper och utvärderingarna visar att inslag från äldre läroplaner präglar undervisningen. För att ge en bild av hur nuvarande problem kan ha uppstått presenteras i studien en histoThe art education in Swedish primary and secondary schools is far from perfect and as a result pupils seldom reach the desired standard. National evaluations in 1989 and 1992 confirm this. Teachers admit that they lack specific subject knowledge and evaluation reveals that many aspects of older curricula still prevail. The way in which the present problems may have arisen is described through the
Evacuation model capabilities are rapidly improving, allowing the simulation of ever more complex scenarios in different types of environments. The definition of the best evacuation modelling approach for safety assessment is a key point for optimizing engineering work and ensuring the desired safety conditions. In the present thesis, a wide comparison between modelling approaches has been provide
The problem of empty names derives from the fact that empty names fail to refer. The reference failure of empty names implies that sentences containing empty names lack truth-conditions. As a consequence those sentences are meaningless, according to many theories of meaning. The present dissertation addresses the problem of empty names and proposes a solution to the problem at hand. In brief, the
In the discipline of archaeology death has always been a common subject. Graves and dead bodies in different states of decay are important sources of information. This dissertation investigates how our relation to death can be mirrored through some of the better-known individuals from prehistory in Scandinavia. Because of the character of the question at issue I start with three chapters in which
In 1822 the Parliament of the United Kingdom passed The Cruel Treatment of Cattle Act, which today is considered to be an important forerunner to modern animal protection and anti-cruelty legislation. However, the new Enlightenment attitudes to animals stemmed from an overly anthropocentric perception of the natural world and the place of the human animal in it. At the heart of the movement agains
Construction projects affect the community in both positive and negative ways. Positive effects are, for instance, better communications, better housing, and a higher standard of living. However, construction projects inevitably bring with them deterioration and changes on the local plane, at the site of the construction project. Thus, in construction projects, many different and sometimes controv
Popular Abstract in English In this thesis we investigate the manipulation of the magnetic properties of molecular magnets by means of external electric fields. This manipulation is mediated by either the spin-electric coupling or the magnetic anisotropy of the molecular magnet. In order to understand what this means, let us first explain some basic concepts about magnetism. We will start explainiThis dissertation investigates theoretically electric control of the magnetic properties of molecular magnets. Two classes of magnetic molecules are considered. The first class consists of molecules that are spin frustrated. As a consequence of the frustration, the ground-state manifold of these molecules is characterized by states of different spin chirality, which can be coupled by an external e
The main goal of SASPENCE is to develop and evaluate an innovative system able to perform the Safe Speed and Safe Distance concept, that means to help the driver in avoiding accident situations related to excessive speed or too small headway. So, the system should co-operate seamlessly with the driver, suggesting the proper velocity for the given condition (road structure, traffic situation, etc.)
Normative reasons are of constant importance to us as agents trying to navigate through life. For this reason it is natural and vital to ask philosophical questions about reasons and the normative realm. This thesis explores various issues concerning reasons and normativity. The thesis consists of five free-standingpapers and an extended introduction. The aim of the extended introduction is not me
Background: Intraventricular hemorrhage causes significant lifelong mortality and morbidity, especially in preterm born infants. Progress in finding an effective therapy is stymied by a lack of preterm animal models with long-term follow-up. This study addresses this unmet need, using an established model of preterm rabbit IVH and analyzing outcomes out to 1 month of age. Methods: Rabbit pups were
The articles included in this thesis centre on what can be called the normative basis of risk analysis. Since risk analyses are decision procedures, they should adhere to norms of rational decision-making, and this they do. Most risk analysis schemes are built on a notion of the decision theoretic maxim that the goal of every decision is to maximize expected utility. However, for some thirty years
The advancement of mobile technologies and their ability to utilize the Global Positioning System (GPS) to accurately locate their substantial number of users, prompt Location-Based Services (LBS) significantly. Ride-sharing is a popular means of transportation that utilizes LBS. With the rapid development of smart cities and their impact on addressing the critical issues of urban life such as tra
