Computational Methods for Hybrid Systems

This thesis considers two different computational approaches for the analysis and synthesis of nonlinear systems. Each of these approaches is presented in a conference paper that describes parts of the theory and algorithms. Matlab commands implementing the algorithms have been developed and the manuals for these are included herein as well.

Routine perinatal postmortem radiography in a peripheral pathology laboratory

Routine postmortem radiography was done in 234 consecutive perinatal autopsies. Using ossification centre appearance and length of femoral shafts as variable it was a very useful and dependable method for estimating gestational age and intrauterine growth. In this way important conclusions can be drawn as to the reason for intrauterine growth deviations. Also many, sometimes diagnostic, abnormalit

Decreased VIP and VPAC(2) receptor expression in the biological clock of the R6/2 Huntington's disease mouse

Huntington's disease (HD) is a fatal genetic neurodegenerative disorder caused by a CAG triplet repeat expansion in the gene encoding the protein huntingtin. The most studied model of HD, the R6/2 transgenic mouse, replicates many features of the disease. In addition to motor, cognitive, and endocrine dysfunctions, these mice exhibit a progressive disruption of circadian rhythms. This is accompani

Hälsovägledning i barnhälsovården : syntetisering av två uppdrag

Popular Abstract in Swedish Denna studie fokuserar på distriktssköterskors hälsovägledning i barnhälsovården. Syftet med studien är att öka förståelsen för hur hälsovägledning utformas och genomförs, samt att generera teori, användbar för praktisk barnhälso-vårdsverksamhet. Data samlades in genom videoobservationer med efterföljande intervjuer, fältanteckningar, anteckningar från gruppdiskussionerChild Health Services (CHS) form a strategic arena for Swedish health promotion, from a societal as well as individual perspective. The present study focuses on district nurses´ health counselling in CHS. The aim is to improve understanding of what is important in shaping and accomplishing health promotion, and to generate theory useful in a CHS context. Data were collected at CHS in primary healt

Language impairment in Swedish bilingual children: a comparison between bilingual and monolingual children in Malmö.

In this study two groups of children were compared, 192 bilingual and 246 monolingual, referred over a 12-mo period to University Hospital in Malmö for suspected language impairment. Compared with monolingual children, bilingual children ran a significantly lower risk (RR = 0.76, p < 0.0001) of being referred by a child health centre, and a significantly higher risk (RR= 1.54, p < 0.0103) of being

Search and analysis of blue straggler stars in open clusters

Aims. This paper presents a new homogeneous catalogue of blue straggler stars ( BSS) in Galactic open clusters. Methods. Photometric data for 216 clusters were collected from the literature and 2782 BSS candidates were extracted from 76 of them. Results. We found that the anticorrelation of BSS frequency vs. total magnitude identified in similar studies conducted on Galactic globular clusters exte

MRI at 3 T of brain functions and fibre tracts adjacent to intracranial tumors

Popular Abstract in Swedish Hjärntumörer är relativt vanligt förekommande och antalet nydiagnostiserade fall per år är i ökande. Vid utredning och uppföljning av patienter med misstänkt eller fastställd hjärntumör spelar bildgivande tekniker en betydande roll, med som förstahands metod magnetisk resonanstomografi (MR). Under det senaste decenniet har MR utvecklats från att framställa bilder på hjäThe aims of the studies were: to evaluate the spatial resolution of fMRI at 3 T by studying fingersomatotopy in area 3 b of the primary sensory area (Paper 1); to investigate the potential of fMRI at 3T as a clinical tool for preoperative evaluation of patients with intracranial tumors (Paper 2); to investigate the effect of glioma resection on the spatial extent of fMRI activation as compared

Imaging by delayed light-emission (phytoluminography) as a method for detecting damage to the photosynthetic system

An improved apparatus for obtaining luminescence (delayed light emission) images of plants is described. It consists of a phosphoroscope equipped with an imaging lens and an electronic image intensifier. It is also equipped with light-sources for obtaining images with reflected light and fluorescence light. Damage to the photosynthetic system caused by virus, insects, high or low temperature, UV r

The influence of different technique factors on image quality of lumbar spine radiographs as evaluated by established CEC image criteria

In this study we have investigated the image quality of lumbar spine radiographs taken after recording technical and physical parameters. Two technical parameters were altered, tube voltage (70 kV and 90 kV for the anteroposterior (AP) projection and 77 kV and 95 kV for the lateral projection) and sensitivity of the film-screen system (sensitivity class 400 and 600). In total, 85 images were inclu

Electronic stopping powers for heavy ions in silicon

The stopping powers in silicon of heavy ions, with atomic numbers ranging from 4 to 29, have been determined using a time-of-flight elastic recoil detection analysis (TOF ERDA) set-up. In transmission geometry, the energy loss of heavy elastic recoils in the self-supporting silicon foil of known thickness is measured over a continuous range of recoil energies using time-of-flight (TOF) spectrometr
