Length and area regularization are commonplace for inverse problems today. It has however turned out to be much more difficult to incorporate a curvature prior. In this paper we propose several improvements to a recently proposed framework based on global optimization. We identify and solve an issue with extraneous arcs in the original formulation by introducing region consistency constraints. The

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

This case book has been compiled within the framework of Phase III of the programme on Regional Air Pollution in Developing Countries (RAPIDC) funded by the Swedish International Development Cooperation Agency (Sida) and coordinated by the Stockholm Environmental Institute (SEI). This work has been produced by the International Institute of Industrial Environmental Economics (IIIEE) at Lund Univer

The thesis has one aim: to investigate the modernist project for design in Sweden and extract its dominant ideals, with the purpose of discussing it critically. The ideals of the modernist project for design make the social democratic thought manifest. These ideals are interpreted as a socialistic aesthetic. The results of the investigation can be summoned up in the following conclusions: When a c

Three pyralid moths, the Mediterranean flour moth (Ephestia kuehniella), the almond moth (Ephestia cautella) and the Indian meal moth (Plodia interpunctella), infest food products all over the world and cause severe problems in factories, shops and households. For health and environmental reasons chemical control becomes more and more restricted. We here present some promising results offering eff

A non-Gaussian time series with a generalized Laplace marginal distribution is used to model road topography. The model encompasses variability exhibited by a Gaussian AR(1) processwith randomly varying variance that follows a particular autoregressive model that features the gamma distribution as its marginal. A simple estimation method to fit the correlation coefficient of each of two autoregres

Vad ska man tänka på när man ska påbörja ett uppsatsarbete i juridik? Hur ska man på bästa sätt disponera sin text och hur hänvisar man till juridiska källor på ett korrekt sätt? Och vad ska man tänka på för att bli klar med uppsatsen i tid? Att skriva rätt ger goda råd när det gäller uppsatsskrivning i juridik. Boken har ett praktiskt fokus och innehåller en mängd konkreta exempel. Den tar upp ol

The conceptual shift in the expectations of wireless users towards multimedia andgroup-oriented computing has a significant impact on today̕s networks in terms of needfor mobility, quality of service (QoS) and multicast routing. Mobile ad hoc networks can provide users with these features. However, it is imperative for them to combine QoS andmulticast routing strategies in order to utilize the wir

Based on observations of the rhythmic structure of L2-speech produced by L1-speakers of Albanian – which suggest the occurrence of transfer – a study is presented here that compares durational aspects between the two languages. In order to do this, speech read by Swedish and Albanian L1-speakers was recorded and investigated, and normalized durational factors were analysed. The results, however, d
