Decision support for product release planning based on robustness analysis

Decision-making in requirements engineering often needs to be done in the presence of uncertainty. Rigorous methods can help to increase the probability of making the most appropriate decisions under the given circumstances. Robustness is a measure for the degree of stability of a solution in case of changes in the problem parameters. This paper presents a method (called DECIDERelease) that applie

Variation in Silene vulgaris and S. uniflora (Caryophyllaceae): genetic diversity, gene flow and habitat selection

Genetic and morphometric variation was studies in the three closely-related taxa Silene vulgaris (a widespread weed), S. uniflora ssp. uniflora (restricted to coastal habitats) and S. uniflora ssp. petraea (endemic to Sweden and confined to open limestone habitats). The majority of alleles at the investigated allozyme loci are common to the three taxa, but the taxa show significant differences in

Social Work Programmes in the Social Democratic Welfare Regime

Abstract in UndeterminedIn this article we examine the emergence of social worker training in the Nordic countries and discuss the possible effects that the social democratic welfare regime has had on such training. We also discuss the development in recent decades of the academisation of the training and the establishment of social work as a subject of research and teaching. The early history of

Electron Tunneling and Field-Effect Devices in mm-Wave Circuits

Popular Abstract in Swedish Arbetet i denna avhandling berör elektroniska komponenter och hur de kan användas i kretsar för trådlös kommunikation. Den huvudsakliga slutsatsen av arbetet är att innovativa och icke konventionella komponenter kan bidra till att förbättra presentanda och minska effektförbrukningen i system för kommunikation på korta avstånd. Framförallt har en krets tillverkats som geShort high-frequency electromagnetic pulses, also referred to as wavelets, are considered for use in various short-range impulse based ultra-wideband applications, such as communication, imaging, radar, spectroscopy, and localization. This thesis investigates field-effect and tunneling based semiconductor devices and their operation in millimeter-wave (mm-wave) impulse transceivers. The main resea

The role of P fimbriae for Escherichia coli establishment and mucosal inflammation in the human urinary tract

Popular Abstract in Swedish Infektioner i urinvägar, tarm och luftvägar orsakas av bakterier som speciellt anpassats till respektive vävnad. Infektionen börjar med att bakterien binder till slemhinneytan, och därmed sätter igång inflammation och försvar. Urinvägsinfektioner (UVI) är en värdefull modell för att förstå de molekylära detaljerna som avgör balansen mellan värd och bakterie. UVI orsakaBacterial adhesion to the bladder mucosa is a critical step for the establishment of Escherichia coli bacteriuria. The P-fimbriae, encoded by the pap gene cluster, are considered as virulence factors but the mechanisms have been debated. This study defined the roles for P fimbriation during the early colonization of the human urinary tract. Patients with recurrent UTI were first subjected to deli

Boundary conditions in the envelope function approximation as applied to semiconductor heterostructures

We have found the equations that determine the self-adjoint extensions, and thus the boundary conditions, of the differential operator used in the multi-band k·p-theory, when the coefficients in the Kane-matrix are piecewise constant. Both the one-dimensional and the three-dimensional case have been investigated. Numerical simulations of the energy eigenvalues in a quantum well has been performed,

Från Orfeus till Eurydike : en rörelse i samtida svensk lyrik

The Orphic myth takes an important position through the history of poetry. Due to the cultural climate the myth has been assumed either to raise the position of the poet or to discuss the limitations of performed poetry. What I aim at in my thesis is to examine how the basic constellations of the myth are again made use of by Swedish poets during the period 1974-1995, and to give evidence of how a
