Lifetime measurements have been made for the radiation emitted in the ground term transitions of the nominal form 5s(2)5p(6)5d(x)6s-5s(2)5p(6)5d(x)6p in Ta II (x = 3), W II (x = 4), and Re II (x = 5). Supporting theoretical calculations have also been performed to characterize configuration interaction and to estimate the degree of decay branching of the upper levels. The lifetime measurements hav
Software applications are of great importance in organisations, and performance of an organisation depends on how hosting of software applications are organised. This thesis deals with the question: Why and how organisations decide on specific sourcing options for software applications hosting. The thesis describes and explains sourcing decision-making processes made in the Swedish Post (MeLo) and
Deep brain stimulation is an accepted technique for the treatment of Parkinson's disease. Deep brain stimulation affects the electrical functions of neurons and several explanations are available to describe this treatment modality. Such as depolarization blockade, synaptic inhibition, synaptic depression and stimulation induced modulation of pathological network activity. An electrical impedance
I here propose a modification of the English butterfly census method (Pollard 1977) for studies of large areas with a relatively low density of butterflies. The transect line should not be more than 10 m from any point in open terrain and open forests, but only 5 m from sunny edges and patches with a high density of flowers. The transect line is adjusted between visits to most intensively cover si
Accuracies reached in space astrometry now permit. the accurate determination of astrometric radial velocities. without any use of spectroscopy. Knowing this true stellar motion, spectral shifts; intrinsic to stellar atmospheres can be identified, for instance gravitational redshifts and those caused by, velocity fields on stellar surfaces. The astrometric accuracy is independent. of any spectral
In this paper, we propose an algorithm for doing reconstruction of general 3D-curves from a number of 2D-images taken by uncalibrated cameras. No point correspondences between the images are assumed. The curve and the view points are uniquely reconstructed, modulo common projective transformations and the point correspondence problem is solved. Furthermore, the algorithm is independent of the choi
Popular Abstract in Swedish Kartering av primärproduktion i Västrafrikanska Sahel genom användning av satellitdata. I avhandlingen har utvecklats en Light Use Efficency (LUE) modell som medger kartering av bruttoprimärproduktionen (GPP) exemplifierad i ett område i Västafrikanska Sahel. Modellen utnyttjar satellitbaserad månatlig Normalised Difference Vegetation Index (NDVI) tillsammans med andraA light Use Efficiency (LUE) model is developed that allows the mapping of total growing season Gross Primary Production (GPP) for the West African Sahel, using the Normalized Difference Vegetation Index (NDVI) together with other data. Image quality may be poor in monthly NDVI maximum value composites as shown by an improved geostatistical noise estimation technique. Quality may be improved by ot
Wireless mesh networks (WMN) have attracted consider- able interest in recent years as a convenient, flexible and low-cost alternative to wired communication infrastructures in many contexts. However, the great majority of research on metropolitan-scale WMN has been centered around max- imization of available bandwidth, suitable for non-real-time applications such as Internet access for the genera
NA44 uses a 512 channel Si pad array covering 1.5 < eta < 3.3 to study charged hadron production in 158 A GeV Pb+Pb collisions at the CERN SPS. We apply a multiresolution analysis, based on a Discrete Wavelet Transformation, to probe the texture of particle distributions event-by-event, by simultaneous localization of features in space and scale. Scanning a broad range of multiplicities, we look f
Planning management activities for a long-term sustainable forestry requires predictive tools designed for this kind of management. Many tools available today are either designed for planning periods that are too short to consider long-term sustainability, omit important parts of the forest ecosystem or are not capable of considering environmental changes. A long-term potential growth-limiting fac
New measurements of radiative lifetimes of four 3d65s levelsin Fe II at about 10 eV are presented along with absolute oscillator strengths for twenty 4p-5s transitions involving the four levels. The experimental measurements are compared with two different sets oftheoretical calculations. The lines are of particular interest in the modeling of HLyalpha pumped fluorescence of Fe II in as
Väderdata från 10 olika meterologiska mätstationer i Sverige - Kiruna, Luleå, Frösön, Söderhamn, Karlstad, Bromma, Jönköping, Säve, Ronneby och Sturup - för tidsperioden 1961 till 1990. De aktuella väderparametrarna är temperatur, relativ fuktighet, ånghalt, mättnadsånghalt, vindhastighet, vindriktning, nederbörd, solstrålning och långvågig strålning.
An alpha/beta barrel is predicted for the three-dimensional (3D) structure of Bacillus subtilis ferrochelatase. To arrive at this structure, the THREADER program was used to find possible homologous 3D structures and to predict the secondary structure for the ferrochelatase sequence. The secondary structure was fit by hand to the selected homologous 3D structure then the MODELLER program was used
OBJECTIVES: To estimate the total direct medical costs to society for patients with type 2 diabetes in Sweden and to investigate how different factors, for example diabetic late complications, affect costs. DESIGN: Cross-sectional data regarding health care utilization, clinical characteristics and quality of life, were collected at a single time-point. Data on resource use cover the 6-month perio
