A new law regarding child-maintenance was issued in Sweden in 1997. The main purpose of the reform was to make the system more cost-efficient, in order to minimise government expenditure. This was done by advocating a more individualised economic responsibility, as well as new rules for how to calculate maintenance levels. Almost five years later it is clear that the economic goals have not been
This paper focuses on the transient behavior of a solid oxide fuel cell system used for stationary power production. Dynamic modelling is applied to identify the characteristic time scales of the system components when introducing a disturbance in operational parameters of the system. The information on the response of the system may be used to specify the control loops needed to manage the change
Combining technology enabled learning and knowledge management is a very promising strategy to systematic competence building in software organizations. In order to set-up a combined learning and knowledge management environment and to support organization members in packaging small chunks of knowledge into courseware modules, Fraunhofer IESE developed the IntView-KM methodology. IntView-KM define
Simulation and computer-aided analysis of complex mechanical systems has become a task of increasing importance in computational mechanics. It requires software tools combining modeling support, efficient generation of the equations of motion as well as modern numerical solution and system analysis techniques.
Popular Abstract in Swedish Modellsystem för metall-DNA interaktioner Med fokus på anticanceraktiva platina(II) komplex Guld är ett mytomspunnet och fascinerande ämne som ger liv. Ett påstående som kanske förvånar, eftersom guld ofta förknippas med vackra smycken och rikedom. Att guld skulle ge liv var dock en förhoppning i Kina på 600-talet f. Kr. Där använde man nämligen metalliskt guld för medReactions of trans-dicyanodichloroaurate(III) trans-dibromodicyanoaurate(III), trans-diamminedichlorogold(III), cis-diammine(aqua)chloroplatinum(II), cis-ammineaqua-(cyclohexylamine)chloroplatinum(II), chloro(terpyridine)platinum(II) and chloro-(diethylenetriaminepalldium(II) with dimethyl sulfide, thionucleosides, thionucleotides and thione- and guanine-containing 17-mer oligonucleotides have bee
A new hybrid ventilation system for low energy buildings has been investigated theoretically using TRNSYS. The system is based on natural ventilation but utilizes a fan during hours when the natural driving forces are not sufficient. Heat from the exhaust air is recovered in an air-to-water heat exchanger. The heated water is pumped to the incoming ventilation air where it is heat exchanged to pre
The research described in this thesis has an interdisciplinary approach dealing with chemical, biological, and technical issues. One objective was to interface miniaturized liquid chromatography (LC) to mass spectrometry, i.e. MALDI-TOF MS and ESI-MS, in an unattended mode for high sensitivity determination of proteins and peptides. The coupling between capillary LC and MALDI was accomplished by e
Common practice in industry is to rotate the milling cutter in only one direction even though the geometry of the inserts are thus that they could be used again while the milling cutter is rotating in the opposite direction. The aim of this study was to investigate to what extent it is possible to increase the tool utilization during milling by first rotating the milling cutter in one direction un
One significant environmental impact from assembly operations includes packaging material use and subsequent waste generation. Although current practice involves reduction of unnecessary materials handling, there is potential to adapt packaging material in order to simultaneously improve the environmental performance and reduce cost in a “lean and green” mindset. Hence, with increased emphasis on
A method is described for identifying simultaneous signals from different transmit antennas in multi-antenna sounders. Multiple orthogonal signals are produced from one pseudorandom code by using it to modulate RF carriers at pre-calculated offset frequencies. Although their frequency spectra are interleaved, the spectral lines from different transmitters are separable by Fourier transform at the
A virtual reality (VR) experiment with 96 participants was carried out to provide recommendations on the design of flashing lights on emergency exit portals for road tunnel emergency evacuation. The experiment was carried out in a Cave Automatic Virtual Environment (CAVE) laboratory at Lund University. A set of variables has been investigated, namely 1) Colour of flashing lights, 2) Flashing rate,
En skola för alla – är ett uttryck som beskriver en politisk ambition att skapa en för alla elever likvärdig grundskola i Sverige. Som verklighetsbeskrivning har uttrycket emellertid sina begränsningar och det är just det som utgör bakgrund till föreliggande text. En skola för alla har vi kanske främst om man väljer att fokusera på olika strukturella förhållanden: skolan är obligatorisk för alla u
The Cone Calorimeter test method has been one of the most used small-scale fire test method for years now and is at present widely spread over the world. In contrast to many other fire test methods, the Cone Calorimeter provides a range of data with sound scientific basis, which allows a wide range of applications. It can be used for modelling and also for enhanced product development. This paper
