A large part of the Earth’s turnover of resources is associated with buildings and building construction. There is therefore a complex relationship to be taken into consideration when realizing construction projects, since economic and social aspects also affect individual people. In order to gain an overall perspective on this relationship during the construction process, one solution is to adapt

How are longings for intimacy engendered in different ways in relation to technology use? How can alternative uses of consumer electronics make us more aware about the conditions for mediation and technology use? The presentation will reflect on a specific consumer electronics product called the Intenso Viddy, which is a cheap video messenger marketed as a lifestyle/mobility-gadget. With it’s inco

This thesis describes the initial development of a new high-brightness table-top soft X-ray source suitable for microscopy. The laser-plasma utilises liquid droplets as targets and the absolute line emission in the water window (A-=2.3-4.4 nm) is typically 1·1012 photons/(stedine·pulse). The narrow bandwidth radiation makes the source suitable for zone plate optics used in microscopy. Compared to

One way to avoid vanishing dissipative energy and localization to zero volume when examining localization and softening problems, is to introduce an internal length scale for the material by means of couple-stress theory. Here, the ‘constrained’ Cosserat theory is adopted where the displacement field also determines the rotation field. For this ‘constrained’ Cosserat theory an elasto-plastic theor

This paper presents a methodology to reduce the power consumption, silicon area, as well as increasing the performance, in digital filters that are feasible for wireless communication circuitries. The method is based on arithmetic reductions in a wave digital filter. Basically, the multipliers are removed to reduce the number of arithmetic operations. All parameters including the dynamic and stati

This contribution outlines an XML format for representation of differential-algebraic equations (DAE) models obtained from continuous time Modelica models and possibly also from other equation-based modeling languages. The purpose is to offer a standardized model exchange format which is based on the DAE formalism and which is neutral with respect to model usage. Many usages of models go beyond wh

Our society is becoming more and more dependent upon the reliable function of a number of vital socio-technical systems. These systems are often being referred to as critical infrastructures, or lifeline systems, indicating their importance for supporting a nation’s economy and social well-being. In the present paper a method is presented for assessing the capability of those actors involved in re

Efter ett par terminers erfarenhets med en lättare variant av samarbetslärande inom matematikundervisningen på LTH, har försöket utvärderats via en enkät. I utvärderingen fokuserade vi på genusaspekten för att försöka ge svar till frågan om kvinnliga och manliga teknologer hade olika inställning till arbetssättet. Resultaten visar att det finns ett överlag positivt mottagande till metodiken bland

Freshly ejaculated human semen has the appearance of a loose gel in which the predominant structural protein components are the seminal vesicle-secreted semenogelins (Sg). The primary structure of the 439-residue SgI has previously been obtained by cDNA cloning. This cDNA cross-hybridizes to a larger transcript coding for a second secretory protein, SgII. Here we report the almost complete structu
