The isoscalar dipole (compression) mode is studied first using the schematic harmonic-oscillator model, and then the self-consistent Hartree-Fock (HF) and random-phase approximation (RPA) are solved in coordinate space. Taking Pb-208 and the SkyM* interaction as a numerical example, the spurious component and the strength in the continuum are carefully examined using the sum rules. It is pointed o
This report describes the derivation of a nonlinear model of a tractor-semitrailer combination vehicle. The purpose of the model is validation of yaw-control algorithms. The model include 4 DOF in lateral, longitudinal, and yaw motion. It is formulated as a state-spece model with 5 state variables. Additional states are added with the rotational dynamics of the wheels. The model includes a static
A scoring system could be used in all situations where grading of deep leg vein thrombosis (DVT), including mapping of its distribution, is needed. It should also be used in epidemiological studies of DVT in further analysis of different risk groups suffering from DVT. Several scoring systems have been developed during the last three decades but have resulted in various complex and impractical sys
Popular Abstract in Swedish Resenärernas värderingar av kvalitet i lokal kollektivtrafik – hur man kan mäta dem, hur de varierar och hur man kan använda dem i planeringen Syftet med arbetet har varit att ta fram ett mer detaljerat underlag för planering av lokal kollektivtrafik. Med mer kunskap om hur olika grupper av resenärer värderar olika delar av en kollektivtrafikresa kan kollektivtrafiknätThe aim of this work was to get a more detailed basis for planning of local public transport. With more knowledge of how segments of travellers assess different parts of a journey, bus routes can be planned to fit either all passengers or selected groups better. It will also be possible to evaluate perceived travel utility separately for each category of passengers. Stated Preference questionnaire
A 3D finite element (FE) model of an implanted pelvis was developed as part of a project investigating an all-polymer hip resurfacing design. The model was used to compare this novel design with a metal-on-metal design in current use and a metal-on-polymer design typical of early resurfacing implants. The model included forces representing the actions of 22 muscles as well as variable cancellous b
A general question for linkage disequilibrium-based association studies is how power to detect an association is compromised when tag SNPs are chosen from data in one population sample and then deployed in another sample. Specifically, it is important to know how well tags picked from the HapMap DNA samples capture the variation in other samples. To address this, we collected dense data uniformly
Fiberoptic bronchoscopy with bronchoalveolar lavage and protected specimen brush technique has become an established method for etiologic diagnosis in severe forms of pulmonary infections during recent years. In this study, including 62 bronchoscopies in 53 patients, a standardized program, covering all important pulmonary pathogens, has been evaluated in a heterogeneous group of patients. Results
We have found necessary and sufficient conditions for the n-particle density to be N-representable for infinite A, if n is even. There are some mild restrictions on the one-density for these conditions to apply. The method is based on the Mercer expansion theorem. We suggest a simple method for total energy calculations based on this characterization also if the number of particles is finite. (c)
