Polymer dispersions are employed in a wide variety of applications as film formers. Especially in the coating-, paint-, pharmaceutical and hygiene industry polymer dispersions are to a large extent used as barriers, controlled-release agents and adhesives. Control and steering of the polymerization process has resulted in the production of core-shell structures with soft and hard (low glass transi

To improve traffic safety it is important to evaluate the safety of roads and intersections. Today this requires a large amount of manual labor so an automated system using cameras would be very beneficial. We focus on the geometric part of the problem, that is, how to get accurate three-dimensional data from images of a road or an intersection. This is essential in order to correctly identify dif

The deregulation of the European transport market has been a controversial topic, characterised by a lack of facts and figures on the actual impact of the regulations. Given the crucial importance of road freight transportation to European society, and the lack of figures and control of foreign vehicles operating domestically in other countries, the purpose of this paper is to present a novel, inn

Critical systems must comply with safety standards in many application domains. This involves gathering safety evidence in the form of artefacts such as safety analyses, system specifications, and testing results. These artefacts can evolve during a system’s lifecycle, and impact analysis might be necessary to guarantee that system safety and compliance are not jeopardised. Although extensive rese

The book chapter gives a picture of experiences made in European comparative research projects with regard to e.g. organisation, style of cooperation, academic culures, language and the social construction of concepts.

In The Geometry of Meaning, Peter Gärdenfors proposes a theory of semantics that bridges cognitive science and linguistics and shows how theories of cognitive processes, in particular concept formation, can be exploited in a general semantic model. He argues that our minds organize the information involved in communicative acts in a format that can be modeled in geometric or topological terms—in w

Popular Abstract in Swedish Avhandlingen behandlar det grekiska landskapet Argolis på östra Peloponnesos och vissa aspekter av livet där under drygt 600 år av romersk överhöghet. I området har man från den tiden funnit lämningar av städer, byar, villor och gårdar så väl som speciella anläggningar för framställning av olivolja, vin och keramik, dessutom badanläggningar, akvedukter, stenbrott, hamnaThis study focuses on the region of Argolid in the eastern part of the Greek Peloponnese during the Roman Imperial era, taking up a variety of aspects of life there based mainly on archaeological evidence. The introduction presents the study area and the background to the study. This is followed in the next chapter by a survey of the various kinds of sites of Roman date found in the Argolid. Citie

Theory of elasticity is the most used assumption in pavement design. Highway materials are neither elastic nor homogenous. Therefore there is a need for models which are based on more realistic assumptions. UGM shows time dependency in nature. This is reflected in a viscous response close to the surface and an elastic response deeper down the construction. Time dependencies of soils are relatively
