In this thesis, we develop and examine decision models intended for traffic engineering analysis of multiservice networks. Two important issues are addressed, namely call admission and routing control in multiservice broadband networks, and overload control in distributed-memory systems. Multiservice broadband networking generally refers to the ability to handle widely disparate traffic streams s

It is commonly accepted that among recent fishes the lungfishes are the closest relatives of the tetrapods. According to this hypothesis, the tetrapods, lungfishes and coelacanths constitute a group of specialized fishes (Sarcopterygii) to the exclusion of other bony fishes. Here, we describe basal relationships among gnathostome (jawed) vertebrates as reconstructed by analysis of complete mitocho

The medical device industry is a constantly growing domain which makes use of more and more software products. Given the importance to this industry of dependable software components, rigorous software engineering techniques would seem to have an important role to play. However, in a recent survey of the industry we found a lower than expected rate of adoption of certain sound software engineering

Reversed phase continuous full filling capillary electrochromatography with electrospray ionisation mass spectrometric detection was performed with highly sulphated poly [styrene-co-(lauryl methacrylate)-co-(divinylbenzene)] nanoparticles. The nanoparticles that contained a hydrophobic core and a hydrophilic surface were prepared in a one step synthesis using soap free emulsion polymerisation. By

The variability in the morphology, modal number of chromosomes, TCR expression and functional reactivity of a CII-specific T-cell hybridoma at continuous subcultivation have been investigated. As the number of passages increased, besides the oval semiadherent cells (normal phenotype), fibroblast-like cells (transformed phenotype) were also observed. The two cell subpopulations differed in their ka

How people react to a fire alarm has been studied in retrospect as well as in experiments. In the present study, the choice of exit was examined with respect to the distance to exits and open or closed emergency exit. The second part deals with some communication aspects regarding identification of signs. It is shown that the subjects prefer a familiar ordinary cash exit even if the distance to th

Several wader species breeding in agricultural landscapes are declining in Europe. Here, we present evidence that reproduction in a subpopulation of an abundant but vulnerable wader species, the Redshank Tringa totanus, is too low for self-sustainability. We used population data collected from Gotland, SE Sweden, during the breeding seasons of 1997[long dash]2003. We used analytic and simulation-b

Systemic vasculitis associated with autoantibodies to neutrophil cytoplasmic antigens (ANCA) is the most frequent cause of rapidly progressive glomerulonephritis. Renal failure at presentation carries an increased risk for ESRD and death despite immunosuppressive therapy. This study investigated whether the addition of plasma exchange was more effective than intravenous methylprednisolone in the a

The aim of this thesis was to empirically and methodologically investigate health related quality of life (HRQoL) among persons 65 years or older with chronic heart failure. The design was cross-sectional and the sample was recruited from a southeast region of Sweden. The sample included 357 respondents in Paper I, II and IV and 349 respondents in Paper III. For all respondents the mean age was 79

Background: There are at least three broad conceptual models for the impact of the social environment on adult disease: the critical period, social mobility, and cumulative life course models. Several studies have shown an association between each of these models and mortality. However, few studies have investigated the importance of the different models within the same setting and none has been p

Results on the study of localized fluctuations in the multiplicity of charged particles and photons produced in 158A GeV/c Pb+Pb collisions are presented for varying centralities. The charged versus neutral particle multiplicity correlations in common phase space regions of varying azimuthal sizes are analyzed by two different methods. Various types of mixed events are constructed to probe fluctua

An analysis of inelastic photoproduction of J/psi mesons is presented using data collected at the ep collider HERA corresponding to an integrated luminosity of above 80 pb(-1), Differential and double I < P-t/psi(2) < differential cross sections are measured in a wide kinematic region: 60 < W-gammap < 260 GeV, 1 p(t,psi)(2) < 60 GeV2 and 0.05 < z < 0.9. where z is the fraction of the energy of the
