Computationally hard problems, such as operations on n-dimensional maps, are in need of efficient solutions. Cellular Neural Networks have this promise. This paper explores digital realizations of such computational paradigms through the case of real-time image processing. It is shown that a behaviour-based spatial unrolling of the time-critical numerical convergence loop outperforms a classical f

Recent results have shown that denoising an image with the Rudin, Osher and Fatemi (ROF) total variation model can be accomplished by solving a series of binary optimization problems. We observe that this fact can be used in the other direction. The procedure is applied to the two-phase, piecewise constant Mumford-Shah functional, where an image is approximated with a function taking only two valu

The increasing demand for solid biofuels, such as primary forest fuels, has highlighted the importance to consider that they, in contrast to fossil fuels are produced in dynamic ecosystems. Environmental effects of changes in ecosystem management policies, positive and negative, are not obvious. To that end, calculations of carbon budgets in single forest stands show that the carbon balance dramat

The aim of this study was to analyse whether the interleukin-1 (IL-1) and IL-6 gene polymorphisms were associated with the susceptibility of chronic periodontitis. Genomic DNA was obtained from 20 patients with chronic periodontitis and 31 periodontally healthy subjects. All subjects were of North European heritage. The test subjects were kept in a maintenance program after periodontal treatment b

Switched capacitors are here investigated for use in reconfigurable matching networks, particularly for DVB-H frequencies. A $0.13$ $mu$m CMOS circuit is evaluated through both simulations and measurements. Source grounded NMOS transistors are used to switch high quality metal capacitors located above metal layer 8. The quality factor and tuning range depend on frequency, switch voltage, capacitor

This project aims to highlight the manufacturer as an important asset in product development. In order to design a product, it is necessary, especially for industrial designers to have good knowledge of the manufacturing technologies that are available and to have knowledge of the working environments in which our ideas are put into practice. Increased cooperation between local actors opens opport

Denna studie syftade till att undersöka om rekryterare upplever att det förekommer etnisk diskriminering mot den ansökande under rekryteringsprocessen, samt om rekryterare upplever moralisk stress. Den syftade också till att se om det finns ett samband mellan rekryterares moraliska stress och deras erfarenhet av etnisk diskriminering. En enkät gjordes med hjälp av både tidigare befintliga frågor sThis study aimed to investigate whether recruiters experience ethnic discrimination against the applicant during the recruitment process, as well as whether recruiters experience moral stress. It also aims to see if there is a relationship between recruiters' moral stress and their experience of ethnic discrimination. A survey was made using both a pre-existing questionnaire and self-construct

Syftet med den här uppsatsen är att undersöka om takvolym är analogt tillämpligt på dynamiska inköpssystem. De senaste åren har prejudikat förändrat synen på vad som maximalt kan avropas inom ett ramavtal. Det skapar följdfrågor om takvolym kan tillämpas analogt på dynamiska inköpssystem, vilket är uppsatsens huvudsakliga fråga. Uppsatsen kommer att börja med att introducera upphandling i stora drThe purpose of this essay is to investigate the possibility of applying “ceiling volume” onto a dynamic purchasing system. Ceiling volume means the requirement to specify a maximum volume of supplies or services. In recent years legal cases have changed the view of the maximum volume that can be awarded during a given period within a framework agreement. A question has now been raised as to whethe
