The use of coarse-grain reconfigurable architectures (CGRA) is a suitable alternative for hardware acceleration in many application areas, including digital holographic imaging. In this paper, we propose a CGRA-based system with an array of processing and memory cells, which communicate using a local and a global communication network, and a stream memory controller to manage data transfers to ext
This paper explores the potentials of solid oxide fuel cells (SOFCs) as 3 kW auxiliary power units for trucks and military vehicles operating on diesel fuel. Various issues are discussed, e.g., the requirements and specifications for the unit as well as the advantages, challenges, and development issues for SOFCs in such applications. System design and analysis are carried out. The major component
Tourism has complex relationships with weather and climate, and there is consensus that tourism could be substantially affected by climatic change. While considerable research has been presented on how climatic change is likely to affect destinations and tourism stakeholders in the future, there remains limited understanding of the weather preferences of tourists. This is a research priority if th
A strategically minded CFO will realize that strategic corporate risk management is about finding the right balance between risk prevention and proactive value generation. Efficient risk and performance management requires adequate assessment of risk and risk exposures on the one hand and performance on the other. Properly designed, a risk measure should provide information on to what extend the f
The accuracy of NOAA AVHRR NDVI maximum value composites can be poor due to interference from several sources, including cloud cover. The objectives of this paper are; 1. to accurately quantify noise in this imagery over Africa using geostatistics, and 2. to test four compositing techniques that may be able to reduce this noise. The nugget of the variogram model is used to compute standardized noi
Popular Abstract in Swedish Under senare tid har hävdats att den IT/media-drivna så kallade "nya ekonomin" starkt etablerats. Enligt många påverkar IT/media teknologier marknadsföring och affärsverksamheter på ett 'revolutionerande' sätt. Denna avhandling behandlar kritiskt och strategiskt konstruktionen av värdeskapande affärserbjudanden där IT/media används. Vidare utvecklar författaren grundlägThis dissertation addresses the design of value productive episodes at the customer/firm boundary. Its purpose is: To provide perspective and help articulate strategies for increasing precision of the design of interactive marketing and value productive efforts at firm/customer boundaries. Many observers, thinkers and practitioners of marketing and management are: (1) Struggling to comprehend and
A critical assessment of a widely applied approach for the prediction of temperature-insensitive absorption lines is presented. This approach was found to suffer from significant shortcomings.
The major challenge in the development of new polymer membranes for fuel cells lies currently in the demand for durable membranes that allows fuel cell operation at high temperatures without extensive humidification requirements. Access to these membranes promises important benefits concerning the complexity, cost and performance of the fuel cell system. In this context, membranes functionalized w
We consider the decoding of LDPC codes in presence of non-Gaussian noise, especially a set of ¿-mixture models. For each of these models, the optimal LLRs are presented. We study the performance degradation due to the use of incorrect LLR in presence of a given noise model. Without modifying the existing LDPC decoder, we propose robust initial LLR which require minimum knowledge about the underly
The paper deals with various initiatives undertaken, or to be undertaken, by Government of Botswana, and which may be looked upon as "Information Society" initiatives. These initiatives are critically analysed and conclusions are drawn from the authors' analysis. Based on conclusions, the authors make certain recommendations regarding implementation of the initiatives.
We present the first results from several ongoing studies of the stellara bundances, ages, and chemical trends in the long-lived dwarf stars in the solar neighborhood that belong to the thin and thick galactic disk.We confirm that the trends of α-elements in the thin and thick disk are distinct, and we also find that the thick disk show the typical signature of SN Ia contribution to the chemical e
Ukraine (UA) has large biomass potentials, and faces broad needs for energy security enhancement, agricultural sector revitalisation and environmental improvement. Cross case study analysis is applied to nine straw-fired installations in UA within a conceptual framework developed by the authors. The analysis yields three distinct straw-based frameworks for organisation and action including ‘small
This study is concerned about the effects of brine discharge into the Arabian Gulf and desalination plants location also. The major concern is the Arabian coastline of the Gulf countries which started from Kuwait whole way to United Arab Emirates. Different scenarios for desalination plant and brine discharge management in the Arabian Gulf are discussed using mass balance computations. The Arabian
Experiments on dry face turning offunctionallygraded heat treatable steel are conducted. The workpieces have a hardened zone of approx. 60 HRC and a non-hardened zone of approx. 30 HRC. PCBN tools are used with different feeds, cutting speeds and depths of cut. Measurements of residual stresses in the surface layer reveal compressive stresses in the hardened zone and tensile stresses in the non-ha
In modern industrialised society prepared meals and eating out of home is an increasing phenomenon. This develops new business opportunities for food manufacturers, since they need to create more convenience to the consumers through food that can be prepared and served quickly. However, the new food products require increased quality and safety and thereby more controlled distribution. The issue i
