Two methods for estimating the sensor offset of a cylinder pressure transducer are developed. Both methods fit the pressure data during pre-combustion compression to a polytropic curve. The first method assumes a known polytropic exponent, and the other estimates the polytropic exponent. The first method results in a linear least-squares problem, and the second method results in a nonlinear least-

Based on a study of Swedish and Finnish industrial design consultancies (IDCs) we discuss how changes in industry have affected id-consultancies cope with growth, organizational and management issues. The traditional industrial designer worked in a small consultancy mainly with clients focusing on mass-produced products. The clients were basically domestic even if they operated worldwide. Investme

The relative benefits and harms of hormonal treatment (HT) versus no or deferred HT in patients with nonmetastatic prostate cancer (PCa) relapse after primary curative therapy are controversial.

Primary objective was to identify the (1) relationship of clinical severity of urosepsis with the pathogen spectrum and resistance and (2) appropriateness of using the pathogen spectrum and resistance rates of health-care-associated urinary tract infections (HAUTI) as representative of urosepsis. The secondary objective was to provide an overview of the pathogens and their resistance profile in pa

The radiative lifetime of the 1s2p(1)P state of helium is measured in a two-colour ionization experiment with a 5% accuracy. The state is excited by the 13th harmonic of a tunable 80 ps laser and ionized by a synchronous ultraviolet laser, with a variable time delay. This experiment demonstrates that the high harmonics generated in a jet of rare gas exposed to an intense laser field provide a tuna

The main purpose of this article is to discuss the kinds of mental representations that are required for language to evolve. Firstly, I distinguish between cued and detached representations. A cued representation stands for something that is present in the current external situation of the representing organism, while a detached representation may stand for objects or events that are neither prese

The periodontal pathogen Porphyromonas gingivalis is highly resistant to the bactericidal activity of human complement, which is present in the gingival crevicular fluid at 70% of serum concentration. All thirteen clinical and laboratory P. gingivalis strains tested were able to capture the human complement inhibitor C4b-binding protein (C4BP), which may contribute to their serum resistance. Accor

This doctoral thesis examines early medieval Slavic migration to the island of Bornholm (Denmark). With a combination of interdisciplinary theories and approaches, which focus on human translocation and memory and identity construction, a holistic approach to the studies of migration in archaeology is proposed. It is argued that in order to address cases of migration it is necessary to consider th

OBJECTIVE: To compare the effects of green foam with black foam and gauze during negative pressure wound therapy (NPWT), with regard to wound bed appearance and granulation tissue formation, and monitoring of wound exudate. METHOD: Wounds on the backs of eight pigs underwent 72 hours of NPWT plus either green polyurethane foam with an open pore structure, black polyurethane foam with an open pore

The Nordic countries Norway, Sweden, Finland and Denmark have formed a deregulated power market. Electricity bought and sold on this market is dominated by hydro power. However, hydro power generation is restricted by the amount of water in reservoirs. The inflow to these reservoirs shows a yearly cycle and seasonal planning of the production is necessary. Seasonal planning for a fictive power pr

A relatively short overview on fascism and nazism in contemporary Europe.

Popular Abstract in Swedish Det tillgängliga frekvensutrymmet i trådlösa kommunikationssystem, så som trådlösa datornätverk, är mycket begränsat. Detta tillsammans med den ökande trafikmängden skapar problem. Nya möjligheter finns dock i och med att det finns stora mängder bandbredd som är licensfri för användning. Ökad bandbredd möjliggör också ökad datahastighet. Det tillgängliga frekvensbandet The available bandwidth in wireless communication systems, such as the 802.11 family, is very limited. Together with the ever increasing data traffic, this causes problems. New possibilities are, however, available thanks to wide license-free bandwidth allocated at higher frequencies. Increased available bandwidth enables higher data rates in future radio systems that will be capable of Giga-bit/s
