A family of active distances for convolutional codes is introduced. Lower bounds are derived for the ensemble of periodically time-varying convolutional codes.

This paper is an exploratory discussion of place and space from a cultural geographic point of view. On the one hand it discusses the concept of place, trying to identify some of its characteristics connected to different Nordic understandings of landscape and place; this will take departure in people’s practice in place and landscape. It will on the other hand discuss the more abstract concept of

Popular Abstract in Swedish I vårt dagliga liv kommer vi i kontakt med en rad produkter som tillverkas av arbetare som riskerar att drabbas av sjukdomar till följd av sin arbetsmiljö. De organiska syraanhydriderna är industriellt vanligt förekommande kemikalier. Två av dessa anhydrider har studerats i denna avhandling, nämligen hexahydroftalsyra anhydrid (HHPA) och methylhexahydroftalsyra anhydridThe aim of this thesis was to describe the metabolism and to develope methods for biological monitoring for two organic acid anhydrides (OAAs), namely hexahydrophthalic anhydride (HHPA) and methylhexa-hydrophthalic anhydride (MHHPA). The OAAs are reactive, low molecular weight chemicals used in vast quantities in the industry. Many OAAs, including HHPA and MHHPA, are potent IgE sensitisers inducin

Trapezoidal cross sections are often used as main longitudinal load-bearing systems in steel-concrete composite bridges. A critical design stage for these girders occurs during casting of the bridge deck, when the non-composite steel section must support the entire construction load, including the wet concrete. A research work was undertaken to study lateral torsional buckling (LTB) capacity and s

In this paper I investigate a particular case of cross-Germanic variation, namely a number of syntactic differences with respect to VP Topicalization, VP Ellipsis and VP Pronomi-nalization. Swedish and English turn out to be the two extremes, with Danish and Norwegaian in between; Icelandic is like Swedish, but lacks the possibility to topicalize VP. Arguments are given for the analysis that the s

This paper reports a case study of leadership processes and the creation of quality assurance routines within a newly formed large department (approximately 260 employees) at a major Swedish university. The study focuses on social actions taken by two assistant heads of departments and twelve assistant directors of study and shows how the two assistant heads of department used listening dialogue a

To compete on a globalized market companies need to constantly improve the performance in their manufacturing systems. Production performance measures can be used for different purposes, by practitioners they are commonly used for follow-up and reporting purposes. Two of the most commonly used performance measures are Overall Equipment Efficiency (OEE) and productivity. Between these two productiv
