In an economic environment signified by shortened product lifecycles, product proliferation and reduced profit margins, product replacement decision making (PRDM) ought to be an important part of management. The case is however often that considerably more energy and resources at a firm are spent at the opposite task, hence product development. The main purpose of this master thesis was to constru

This paper applies the GARCH-MIDAS (Mixed Data Sampling) model to examine whether information contained in macroeconomic variables can help to predict short-term and long-term components of the return variance. A principal component analysis is used to incorporate the information contained in various variables. Our results show that including low-frequency macroeconomic information in the GARCH-MI

We propose a novel interconnector design, termed bi-layer interconnector, for solid oxide fuel cells (SOFCs). It can disturb the fuel gas and air on the planes normal to the SOFC three-phase-boundary (TPB) layer. In this paper, a two-dimensional half-cell model is developed to study the concentration overpotentials in the fuel side of the SOFC stack with conventional and novel bi-layer interconnec

Our purpose with this paper was to examine what effect a parent's drinking problem can have for the children in the family. A combination of literature study and qualitative interview analysis was used. The most important research questions were: How do the parent's problems affect the child? In what ways can the social network around the child help it to develop normally despite problems

By introducing spectral or polynomial functions to perturb the shape of the rotor in an electrical machine that was previously optimized by conventional means, it was shown that performance parameters can be further improved, in some cases significantly. This was accomplished by developing and applying an optimization method designed for use with a commercial finite element simulation software (Ma

After much work and a long time after its instigation, a legislation regulating insolvency law in the European Union finally saw the light of day in 2002. Its 47 articles and 33 recitals establish jurisdiction, choice of law as well as recognition, in cross-border insolvencies within the EU and with this new legislation came a new expression to the legal area, namely 'centre of main interests&

The purpose of this paper is to test a procedure that would be useful for a certain, more final purpose. Assume that you want to know if the differences in the result of a certain effort in health care have any connection with differences between the life situations of the patients. This would be easier to investigate if the life situations of the patients had connection to the easily available va

Uppsatsens syfte är att undersöka återförsäljares uppsägningsskydd och rätt till ersättning vid avtalets upphörande. För ett företag som önskar etablera sig på en ny marknad gäller det att välja rätt exploateringsmetod. Ett alternativ är då att utse en representant som säljer produkten på den nya marknaden. En lokal representant som känner till marknaden och eventuellt redan har ett etablerat försThe purpose of this essay is to examine the retailer’s dismissal protection and the right to compensation for termination of contract. For a company who wishes to establish themselves in a new market it is important to choose the right development approach. An alternative is then to appoint a representative who sells the product in the new market. A local representative who knows the market and po

Volumetry of subregions in the medial temporal lobe (MTL) computed from automatic segmentation in MRI can track neurodegeneration in Alzheimer's disease. However, poor quality MR images can lead to unreliable segmentation of MTL subregions. Considering that different MRI contrast mechanisms and field strengths (jointly referred to as “modalities” here) offer distinct advantages in imaging differen

The word plus(s) can function as a conjunction in Scandinavian, and as such coordinate for example embedded clauses introduced by the subjunction at(t). However, one can also find examples of clauses introduced by plus(s) at(t) although not preceded by another at(t)-clause. These constructions, which represent a relatively new development in Scandinavian, are semantically similar to coordinations

Popular Abstract in Swedish Hur ser vardagen ut för äldre demenssjuka människor? Vad händer när dementa och vårdbiträden dagligen möts i nära och intima relationer? Denna avhandling ger en ingående beskrivning av hur vardagen gestaltar sig på tre gruppboenden för dementa med utgångspunkt från hur dementa och vårdbiträden faktiskt handlar i olika situationer. Ett försök görs att ge ett förståelsepeThis thesis is about the residents and employees at three group homes for older people suffering from dementia. The empirical data comprises princi- pally of participant observation and interviews with caregivers. The aim of the dissertation is to describe and understand what happens during daily life at a group home for elderly suffering from dementia. The ambition is to understand the patterns o

Popular Abstract in Swedish Hur framställer Johannesevangeliet Jesus och effekterna av hans gärning med tanke på de universella och inkluderande drag som finns i detta evangelium? Hur förhåller sig dessa inkluderande drag till framställningen i övrigt och till de begränsande och exkluderande drag som också finns där, och hur ska dessa motstridiga drag i evangeliet förklaras? Denna avhandling sökeMy thesis is an analysis of exclusive and inclusive features i the Gospel of John, focusing on the inclusive elements which comprise the world and all its people. These questions are the issue of my thesis: How does the Gospel of John present Jesus and the results of his work with regard to the universal and inclusive features which are in the Gospel? How do they relate to the presentation in gene

Little is known the evolution of ‘yes’ and ‘no’ in human language, and in this paper, an attempt is made to make a first step in revealing how our ancestor came up with these words. Our analysis starts with Proto-Uralic, and then we compare its developmental path to other languages in the Indo-European family.
It has been documented that in Proto-Uralic (ca. 4,000 BC) there existed e ‘no’, bu

Stamp fabrication for nanoimprinting can be significantly simplified, when specialized crosslinking polymers are applied to pattern definition. The polymer patterns can be used as stamps themselves. Two possibilities are reported: (1) An e-beam sensitive resist was developed, which enables the fabrication of polymer-on-silicon stamps. Patterns with a feature size of 70 nm could be created. (2) Ful

PURPOSE: Retinal ganglion cells (RGCs) are exposed to injury in a variety of optic nerve diseases including glaucoma. However, not all cells respond in the same way to damage and the capacity of individual RGCs to survive or regenerate is variable. In order to elucidate factors that may be important for RGC survival and regeneration we have focussed on the extracellular matrix (ECM) and RGC integr

Companies belonging to the same industrial branch are subject to similar economical influences. Hence, the time series of their stocks can show similar trends implying a correlation. Financial correlation matrices measure the unsystematic correlations between time series of stocks. Such information is important for risk management. It has been found by Laloux et al that the correlation matrices ar
