Rate R=(c-1)/c convolutional codes of constraint length nu can be represented by conventional syndrome trellises with a state complexity of s=nu or by binary syndrome trellises with a state complexity of s=nu or s=nu+1, which corresponds to at most 2^s states at each trellis level. It is shown that if the parity-check polynomials fulfill certain conditions, there exist binary syndrome trellises wi
Large-scale software development is a complex undertaking and generates an ever-increasing amount of information. To be able to work efficiently under such circumstances, navigation in all available data needs support. Maintaining traceability links between software artefacts is one approach to structure the information space and support this challenge. Several researchers have proposed traceabili
When the constructions from the industrial society are abandoned and start to decay, former workplaces gain a new potential. Through activities like urban exploration old abandoned factories become arenas for photographic expeditions. The photos are presented on websites and in books, and are characterized by a kind of postindustrial romanticism. Meanwhile other industrial settings are refurbished
In this paper the frequency domain sensitivity shaping of pole placement controllers is discussed. The sensitivity function is shaped in order to improve robustness and disturbance attenuation, and it is done with the use of controller overparametrization. A design example shows the capabilities of the method. The computation is done by a weighted least squares procedure which is suitable for adap
The anonymous Libellus de Magno Erici Rege gives an outline of King Magnus Eriksson’s reign, painting it in dark colours. The author emphasises that Sweden is an elective, not a hereditary kingdom, and that the king can be deposed if he commits evil deeds and turns into a tyrant. The detailed account of King Magnus’s reign is designed to show that he had wilfully and systematically broken the law,

Since mathematical sociology was firmly established in the 1960s, it has grown tremendously. Today it has an impressive scope and deals with topical problems of social structure and social change. A distinctive feature of today's use of mathematics in sociology is the movement toward a synthesis between process, structure, and action. In combination with an increased attention to social mechanisms
The study objective was to examine the prevalence and course of depressive disorders (DDs) in teenage-onset anorexia nervosa (AN) over a period of 10 years. Fifty-one adolescents with AN and a sex- and age-matched control group (n = 51) were assessed at ages 16, 21, and 24 years. Probands and controls were examined in depth using semistructured and structured interviews. Their parents were intervi
Jag menar att det nät- eller dataspelsberoendekoncept som Wincent saluför är en bluff. Inga trovärdiga belägg för motsatsen har ännu presenterats. De exempel som framförts, likaså de självtest som finns på hemsidan, är särskilt formulerade för att få så många som möjligt att framstå som i behov av behandling.
