We archaeologists are sensitive to the messages people convey through material culture. In Lund, paving stones carry a powrful message about Lund's 1,000-year-old history. However, paving stones are in fact a fairly recent phenomenon dating from the late 19th century. Thus, paving stones do not represent continuity in the longue duree, but they do represent our idea of what the past was like.

During the last ten years or so, much effort has been spent on developing software architecture by analogy with hardware architecture from where the idea seems to originate. Much of the work has been devoted to specifying standard program units, called components, and their connections. The architecture is then the specific organization of these components and connections. In this paper, I suggest

Popular Abstract in Swedish Denna avhandling baserar sig på de erfarenheter av Internet som ett antal människor med betydande kroppsliga funktionsnedsättningar gjort. Personerna i studierna är erfarna och duktiga dator- och Internetanvändare och har få eller inga funktionshinder i dator och online världen, men däremot stora funktionshinder i den fysiska världen. Deras functioning, förmåga attThis thesis is based on the Internet experiences of people with significant mobility/physical impairments who are proficient and experienced computer users in their computer world but have limitations in mobility that severely restrict their functioning in the physical world. The Internet functioning of this group is analysed by means of the factors attitude, control and enabling, with the m

Många pensionssystem är ohållbara. Sverige är ett av de länder som lyckats genomföra en pensionsreform. Kapitlet ger en politisk-ekonomisk analys av hur detta var möjligt.

Popular Abstract in Swedish För mer än hundra år sedan visade Hofmeister och Lewith att vissa salter har mer eller mindre förmåga att destabilisera ett protein upplöst i vatten. Ungefär samtidigt, visade Arrhenius att salter upplösta i vatten dissocierar i olika joner. Joner är laddade stabila partiklar som är mycket viktiga för stabiliteten av kemiska och biologiska system. Det har under de senasUsing experiments it is rather easy to measure things on the macroscopic length scale, while it is much harder to measure something in the microscopic world like molecular structure. The opposite is true in theoretical chemistry. It is today rather easy to calculate a bond distance or a coordination number, but it is not possible to perform a calculation aiming at the description of macroscopic ph

The first standards based on thermal manikin measurements were developed in the 1980s. In the Nordic countries tests for thermal insulation measurements of sleeping bags and cold protective clothing were developed. Similar standards were published in Germany by DIN and in the US by ASTM. At a European level, EN 342 describes test methods and requirements for cold protective clothing based on manik

Short presentation of the concept convergence culture in relation to television

The paper deals with the problem of reconstructing the locations of n points in space from m different images without camera calibration. It shows how these problems can be put into a similar theoretical framework. A new concept, the reduced fundamental matrix, is introduced. It contains just 4 parameters and can be used to predict locations of points in the images and to make reconstruction. We a

Gas turbine maintenance is crucial due to high cost for the replacement of its components and associated loss of power during shutdown period. Conventional scheduled maintenance, based on equivalent operating hours, is not the best alternative as it can require unnecessary shut downs. Condition based maintenance is an attractive alternative as it decreases unnecessary shut downs and has other adva

Some preliminary observations on the rise and development of technical terminologies in Greek and Latin, and their successive influence on the modern European languages and their patterns of word formation

Despite many years of implementations, issues surrounding the success or failure of information systems are still shrouded in mystery. In a quest to improve business outcomes from such systems an IS analyst should have a key role to play. Organisational IS can be seen as a composition of indi-vidual and organisational learning processes, and as such is in a constant state of change. Knowledge as a

Multi-particle production in the central and forward (proton) rapidity region is studied in photoproduction and deep inelastic scattering (DIS). The measurements in the forward region are a factor of similar to 2 larger than QCD predictions based on the DGLAP evolution equations. The central rapidity region is rather well described. Searches for instanton induced processes in DIS are presented.
