To enter new markets is not easy. The most obvious challenge, at least judging from the majority of literature on internationalization, is to understand the new market thus taking a market(ing) perspective. External aspects of internationalization are often stressed, while internal aspects, focusing on why organizations fail, are less developed or examined. In order to better understand the intern
Today, Brahe Church mainly exhibits signs of the period of greatness of Visingsö island during the seventeenth century. However, there are also traces from much earlier periods. Ströja Church was built during the twelfth century, when the House of Erik and the House of Sverker contested for the title of king and the island of Visingsö had a prominent position in the new country of Sweden. We do no
Reasoning with limited computational resources (such as time or memory) is an important problem, in particular in cognitive embedded systems. Classical logic is usually considered inappropriate for this purpose as no guarantees regarding deadlines can be made. One of the more interesting approaches to address this problem is built around the concept of active logics. Although a step in the right d
Impact work-rate of a weakly damped beam with elastic two-sided amplitude constraints subject to harmonic excitation is calculated. Impact work-rate is the rate of energy dissipation to the impacting surfaces. The beam is clamped at one end and constrained by unilateral contact sites near the other end. This system was an object of a vibro-impact experiment which was analyzed in our earlier paper

Popular Abstract in Swedish Lokal behandling med målsättning att förstöra kroppsvävnad genom uppvärmning (termoterapi) kan i vissa fall vara ett alternativ eller komplement till kirurgi. I avhandlingen presenteras utrustning och metoder för att, utifrån en fysikalisk synvinkel, göra sådana behandlingar säkrare och effektivare. Genom att beräkna temperaturefördelningen m.h.a. datorsimuleringar kan Local treatment with the aim to destruct tissue by heating (thermotherapy) may in some cases be an alternative or complement to surgical methods, and has gained increased interest during the last decade. The major advantage of these, often minimally-invasive methods, is that the disease can be controlled with reduced treatment trauma and complications. The extent of thermal damage is a complex fun
A wavelet generator producing 100 ps short pulses at 60 GHz is presented. The wavelet generator consists of a gated tunnel diode (GTD) integrated in parallel with an inductor. This forms a negative differential conductance (NDC) oscillator with the ability to switch the NDC property on and off, which makes it possible to generate short pulses. In the experiments described, the wavelet generator dr
The detection of microorganisms by PCR can be divided into four steps: (1) sample collection, (2) sample preparation, (3) DNA amplification and (4) detection of PCR products. The major problem in developing PCR-based detection methods is the sample preparation step. This step is necessary to overcome problems caused by PCR inhibitors and it determines, to a large extent, the sensitivity of the PCR
Information technology is a vital driver in today’s business environment. Recent developments of IT have facilitated for the relatively easy creation of markets on the Internet, so called B2B-marketplaces. However, judging from the survival rate of B2B-marketplaces (5 to 10 per cent), it seems like B2B-marketplaces are doing something wrong. This paper scrutinises several theoretical frameworks re
“The eyes lead the body.” A good visual environment is important for performance and wellbeing. Unsatisfactory visual conditions often induce a strained posture, more or less unconsciously, in an effort to improve vision. The requirements for the visual environment in an operating theatre are high. Surgeons or assistants who are having visual problems can induce treatment hazards. The purpose of t
Meteor radar observations carried out in August-September 1953-84 at theOnsala Space Observatory in Sweden show long-term, as well as short termvariations in meteor radar rates. These rate variations are associatedwith position in the solar cycle, and with variations in the solar windsector structure. An inverse correlation is found between meteor radarrates and the solar cycle. The magnitude of t
