This chapter addresses the increasingly important issue of effective addressing, object location and presence notification in networks with no infrastructure and dynamically changing environments. This chapter presents Calto, an architecture comprising presence concepts from Second and Third Generation Mobile networks, Instant Messaging Systems subscriber services, and distributed DNS style functi
The mechanical stress build up in fibre handling, the dynamical frictional phenomena between fibres and curved surfaces and formation of dust have been studied. Typical are stick slip behavior and threshold stress levels for formation of dust. The emission of dust can be limited by electrostatic charging. The measured coefficients of friction of the fibres depend on the mechanical properties, micr
The development towards total offers; integrated product and service offers, is a trend in industry, particularly in business to business relations. This strive towards more extended offers can be noticed in a wide range of companies from different branches, and it has important implications on management. Today there is no established method available to handle the extended risks associated with
The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. A special case of bubble transport is the cavitation phenomenon, which mainly has a negative effect on the performance of

When exploring possible energy saving measures for existing buildings different technical solutions should be investigated. In Malmö, Sweden, a 1930s hospital in a park setting has been refurbished with a general sustainability goal. For one of the buildings a glass-façade has been added to an existing 80-year old brick building. Measurements of relevant temperatures have been made including meas
Popular Abstract in Swedish Hur näringsbehovet tillgodoses skiljer sig mellan spädbarn och småbarn. Bröstmjölk och/eller modersmjölksersättning dominerar som källor till energi-och näringsintag under första levnadsåret. I småbarnskosten däremot, tillför komjölk majoriteten av energi, protein och mättat fett, men knappast något järn eller fleromättat fett alls. Flera rekommendationer finns över hurIn the diet for young children, whole cow´s milk is the major contributor of calories, protein and saturated fat, but it supplies little iron and polyunsaturated fat. Although several recommendations exist for the composition of formula, recommendations for the composition of milk for young children are lacking. We investigated if milk with modified fat-, protein-, and iron content aimed at young
The studies described in this thesis focus on the involvement of the two laminin G-type domains of vitamin K-dependent protein S in various biological contexts. The G-type domains are located in the C-terminal sex-hormone-binding globulin (SHBG)-like region. In human plasma, the majority of protein S circulates in a high-affinity complex with the complement regulatory protein C4b-binding protein (
Fast and reliable time and frequency synchronization is crucial for packet-based orthogonal frequency division multiplex (OFDM) systems. In this paper we compare and analyze preambles for OFDM systems based on repeated OFDM data symbols or repeated short pseudonoise sequences (PN-sequences). We make an analytical evaluation for AWGN channels and simulate the performance in oneand two-tap Rayleigh
A support vector classifier was compared to a lexicon-based approach for the task of detecting the stance categories speculation, contrast and conditional in English consumer reviews. Around 3,000 training instances were required to achieve a stable performance of an F-score of 90 for speculation. This outperformed the lexicon-based approach, for which an Fscore of just above 80 was achieved. The
I give an overview of the calculations done in three-flavour Chiral perturbation theory at next-to-next-to-leading order with an emphasis on those relevant for an improvement in the accuracy of the measurement of Vus. It is pointed out that all needed low energy constants can be obtained from experiment via the scalar form-factor in Kl3 decays
The clean development mechanism (CDM), outlined in Article 12 of the Kyoto Protocol (UNFCCC 1997) is one of the most debated and disputed provisions of the current climate regime. Developing and developed states, business as well as environmental NGOs all seem to be dissatisfied with the mechanism in its current shape, and a reform of the CDM is therefore high on the agenda of the climate negotiat
This article outlines a numerical study on the benefit of using High-Performance/Strength Concrete for fabrication of concrete elements. For this purpose a comparison is done between the cost of existing beams with normal strength concrete and optimized beams made of High-Performance/Strength Concrete. A background is given concerning the most essential properties of High-Performance/Strength Conc
Liturgical reform is rampant today. The liturgical movement of the twentieth century has been succeeded by a period of uninformed tinkering with the liturgy by individual priests and ministers. The article identifies and criticizes five possible reasons for reforming (or simply changing) the liturgy.
