Functionality for efficient computation of properties of system lifetimes was developed, based on the Mathematica framework. The model of these systems consists of a system structure and the component’s independent lifetime distributions. The components are assumed to be non-repairable. In this work a very general implementation was created, allowing a large number of lifetime distributions fro...

A comprehensive study of the isomer-independent synthesis of TRIS ((HOCH(2))(3)CNH(2)) Mn-Anderson compounds from Na(2)MoO(4)·2H(2)O, via the corresponding octamolybdate species, is presented. Three octamolybdate salts of [Mo(8)O(26)](4-) in the β-isomer form, with tetramethylammonium (TMA), tetraethylammonium (TEA) and tetrapropylammonium (TPA) as the counter cation, were synthesised from the ...

Everyday work involves communicating, coordinating and collaborating with others. In many cases employees are situated in geographically distributed offices, and hence lack a general sense of their co-workers’ current activities and availability. At present, many companies invest money in communication systems that enable formal interactions, such as video conferencing. There are however few te...

This thesis presents a binocular visual system constructed for fixation of objects of homogenous colour. The purpose of this approach to fixation is to evaluate the use of colour cues, which are well-defined in homogenously coloured regions, where earlier used techniques such as optical flow and correlation are ill-posed. Two colour-based tracking methods are developed and implemented, one prob...

When elastic fibers are immersed in a Newtonian fluid, the behavior of the system, or the “fiber suspension” becomes non-Newtonian. Understanding the dynamics of such systems is of particular interest in a wide variety of fields, including locomotion of microorganisms, paper and pulp industry, microfluidics etc. When these fibers are immersed in the fluid at low Reynolds number, the elastic equ...

The extraction of roads from aerial and satellite images is an important task within cartography and planning of new road networks. The automation of this task is highly motivated by the expected increase of the speed and the precision of extraction. The present work considers automatic road extraction from single aerial images of high resolution. It is based on two previously developed approac...

Organic materials, such as conjugated polymers, have emerged as a promising alternative for the production of inexpensive and flexible photovoltaic cells. As conjugated polymers are soluble, liquid based printing techniques enable production on large scale to a price much lower than that for inorganic based solar cells. Present day state of the art conjugated polymer photovoltaic cells are comp...

The olfactory epithelium (OE) is a useful model to study neurogenesis because of the sustained ability for self-repair throughout adult life. The main aim of this study was to investigate putative neuroprotective roles of fractalkine/CX3CL1 signalling in the olfactory epithelium after experimentally-induced cell death and replacement of olfactory sensory neurons. Previous studies have shown tha...

Pheochromocytomas and paragangliomas are neuroendocrine tumors that arise from neural crest-derived cells of the adrenal medulla and the extra-adrenal paraganglia. They cause hypertension due to an abnormally high production of catecholamines (mainly adrenaline and noradrenaline), with symptoms including recurrent episodes of headache, palpitations and sweating, and an increased risk of cardiov...
