This paper illustrates a novel method to analyze artificial neural networks so as to gain insight into their internal functionality. To this purpose, the elements of a feedforward-backpropagation neural network, that has been trained to detect edges in images, are described in terms of differential operators of various orders and with various angles of operation.

This paper describes the modification of a wavelet based event detector for cardiac pacemakers with improved power efficiency. A previously published R-wave detector has been supplemented with a noise detector that operates in supervision mode, and automatically activates and deactivates parts of the detector. Simulation results show that the power consumption in an ASIC core can be reduced by mor

After the storm. A sociological analysis of families owning forest properties. A Book By Sellerberg publiched by Bokbox, March 2011 "Has it been windy?", someone asks a forest owner in March 2005. In January practically all of his forest was annihilated. A storm rolled by with winds as strong as 46 metres per second. The forest owners in Kronoberg county were particularly badly hit by the disaste

Popular Abstract in Swedish Ett system där flera personer och maskiner kan kommunicera samtidigt över ett gemensam medium kallas ett fleranvändarsystem. Den här avhandlingen presenterar och analyserar olika fleranvändarsystem där mediet består av en radiokanal med hög bandbredd. Analyser av hur många användare som kan kommunicera samtidigt och olika sätt för att öka denna kapacitet är presenterad.Wideband CDMA (Code Division Multiple Access) is one of the key technologies for future mobile communication systems. This thesis studies various coding and transmission methods for wideband CDMA communications. In a cellular environment, the system performance depends on the interference from other cells. An analysis of the other-cell interference in the forward link, from the base station to the

This is the third volume in a serial of books focusing on the concept of mystical death and related ideas, as described within the Christian mystical tradition and its Jewish and Greek roots. In the succeeding chapters these mystical elements and their development are followed up, both within the Western and Eastern Christian traditions. In the final chapters the author presents the German and Dut

Artiklarna i denna antologi belyser hur nutida forskningsrön och vetenskaplig diskussion om frågor som kaos och komplexitet, förutsägbarhet och kausalitet, emergens och ordning påverkar traditionella religiösa och vetenskapliga tankar om oförutsägbarhet, slump, ändamål och skapelse. Teologer och naturvetare från sekulär, protestantisk, katolsk och ortodox tradition visar hur ordning och oordning h

This paper derives a set of policy lessons for Portugal from the new fiscal framework including a fiscal policy council that gradually emerged in Sweden after the deep economic crisis of the early 1990s. By now, Swedish public finances stand out among the strongest in Europe. Recent Swedish macroeconomic performance has been impressive. As Sweden and Portugal are small open economies in the periph

Popular Abstract in Swedish Vi blir alla förkylda, får influensa eller magsjuka någon gång då och då. Smittsamma sjukdomar orsakas av patogener, d.v.s. virus, bakterier eller andra typer av parasiter. De flesta patogener som vi kommer i kontakt med tas om hand av vårt effektiva immunförsvar och vi märker i bästa fall inte av smittan. Huruvida vi blir sjuka eller inte när vi utsätts för smitta, berThe Major Histocompatibility Complex (Mhc) genes are crucial for the recognition of self and non-self peptides by the immune defence system. They are extremely variable in most studied vertebrate species. I have studied the extent and the importance of Mhc variation in Atlantic salmon (Salmo salar), mainly from the Baltic Sea. Levels of Mhc heterozygosity in hatchery populations of salmon were bet

Our aims were to characterize familial hypercholesterolemia (FH) in a Swedish FH population and to further elucidate the clinical expression and treatment response in relation to genotype. Secondly, we wanted to identify gene variants, which may have impact on cholesterol levels in apparently healthy subjects. In the search for sequence alterations in the large LDL receptor gene we introduced and

A linear quadratic control problem is considered, where several different controllers act as a team, but with access to different measurements. The state feedback solution obtained in a previous paper is here extended to output feedback and a separation principle is proved. The condition that certain measurements are unavailable to some state estimators is enforced by imposing a requirement that t

This paper introduces the possibility of increasing the efficiency and minimizing the risk in functions marketing in the aircraft industry by focusing on better control of the logistic parameters. Functions marketing can be described as the marketing of a function rather than a product. The emphasis in this paper will be on the maintenance, i.e. repair and overhaul, of aircraft engines. Functions

The Davies transformation is a method to transform the steering vector of a uniform circular array (UCA) to a vector with Vandermonde form. As this form is similar to that of the steering vector of a uniform linear array (ULA), we can apply to UCAs the many tools that have been developed for ULAs. However, the Davies transformation can be highly sensitive to perturbations of the underlying ideal a

Force feedback (FF) is a technology which is very interesting in the context of human machine interfaces. This as it is usable as a haptic interface, which makes it possible to model and simulate objects and textures. One problem with haptic FF devices today is that most of them are of professional or research standard, which makes them expensive. The technology of FF have also been introduced in

This paper compares grammatical and pragmatic development in foreign language learners of Swedish. For the analysis of grammatical proficiency, data from translation tasks and essays were tested against the stage model proposed in Processability Theory, which identifies five stages of morpho-syntactic development for Swedish (Pienemann 1998, Pienemann and Håkansson 1999). For the pragmatic analysi
