Topics in Modeling, Control, and Implementation in Automotive Systems

This thesis treats different aspects of automotive control-systems and consists of four papers covering different areas in this large field. The first paper presents a 9-degrees-of-freedom dynamic model of a tractor-semitrailer vehicle, aimed at simulation and evaluation of active chassis-systems for stability enhancements. Special focus is put on inclusion of the dynamics of load transfer, which

Samverkan lärare-­studenter nyckeln till lyckad förändring

Vår utgångspunkt är den nya kursen »Individ och samhälle« på den reformerade läkarutbildningens avslutande termin. Som lärare betonar vi vikten av att kompetensmål, arbetsformer och examination hänger samman på ett klart och tydligt sätt, så att de studerande styrs rätt i sitt lärande. Som studerande lyfter vi fram förutsättningarna för en aktiv studerandemedverkan: att involveras medan möjlighet

Determination of Material Properties for Fire Modelling

Fire and flame spread are very complex phenomenon to study. Several aspects need to be considered and treated. In order to be able to do a correct analysis of the flame spread phenomenon, which is necessary to be able to predict flame spread, knowledge of material properties are needed. Material properties can be obtained in different ways. Traditionally material data have been obtained by testin

Smoking and airway disorders in an urban population -special references to gender and socioeconomic status

Popular Abstract in Swedish Delarbetena i denna avhandling, som baseras på en befolkningsstudie från Malmö, studerar sjuklighet och dödlighet associerad till rökning och kroniska luftrörssjukdomar med hänsyn till köns och socioekonomiska aspekter. Studier av män har övertygande visat en ökad mortalitetsrisk associerat med tobaksrökning. Emellertid har endast ett fåtal studier undersökt långtidsefThe Malmö Preventive Project, a preventive, case-finding programme for cardiovascular risk factors and alcohol abuse was created in 1974 at the Department of Preventive Medicine of Malmö University Hospital. Between 1974-1992, a total of 22 444 men (mean age 44 years range 27 - 61) and 10 902 women (mean age 50 years, range 28 - 58) attended the programme, with an overall attendance rate of 70% (r

Pharmacological basis for duration of effect: formoterol and salmeterol versus short-acting beta 2-adrenoceptor agonists

The mechanisms behind the long duration of bronchodilating action of the beta 2-adrenoceptor agonists formoterol and salmeterol are only partially understood. This review compares pharmacological characteristics of long-acting versus short-acting beta 2-adrenoceptor agonists in human and animal airways. Based upon the reviewed evidence, it is concluded that for beta 2-adrenoceptor agonists, long d

Basic accessibility in modern housing--a key to the problems of care in the domestic setting

The purpose of this study was to investigate public grants for housing adaptation in modern housing and to explore attitudes to accessibility problems. Grants for housing adaptation in apartments in blocks of flats built during the 1980s in a Swedish urban district were investigated over a 3-year period. Twenty-nine apartments had been adapted, in most cases by making a few simple alterations. Int

Fallbeskrivning. Rosiglitazonbehandling gav kraftfull effekt, men fick ändå avbrytas

The thiazolidinediones were introduced as oral hypoglycemic drugs in Sweden during the fall of 2000. A case is reported in which a woman with insulin-dependent type-2 diabetes and both macro- and microangiopathy and pronounced insulin resistance was treated with rosiglitazone (Avandia). Within three months insulin doses could be reduced by 36% (from 176 to 112 units insulin daily) and concomitantl

Affinity cryogel monoliths for screening for optimal separation conditions and chromatographic separation of cells

Suitable conditions for separating cells using a chromatographic procedure were evaluated in parallel chromatography on minicolumns. A 96-hole minicolumn plate filled with cryogel monoliths (18.8 mm x 7.1 mm O) with immobilized concanavalin A was used. Chromatographic columns (113 mm x 7.1 mm O) were used for chromatographic resolution of a mixture of Saccharomyces cerevisiae and Escherichia coli

The influence of support layer on mass transport of homologous series of alcohols and esters through composite pervaporation membranes

In this study the effect of the composite membrane structure on the mass transfer limitations in hydrophobic pervaporation of dilute aqueous solutions of homologous series of alcohols and esters was investigated. Three hydrophobic membranes with poly (octyl)methylsiloxane (POMS) as an active layer were used. The membranes studied varied with respect to the thickness of the active layer and the nat

MR imaging as the primary modality for neuroradiologic evaluation of the lumbar spine. Effects on cost and number of examinations

PURPOSE: To evaluate the effects on cost, and number of primary and supplementary neuroradiologic examinations, after introducing MR imaging as the primary modality in the evaluation of the lumbar spine. MATERIAL AND METHODS: Two 5-month periods were compared: period 1--before MR; and period 2--after introduction of a 2nd MR device. In period 1, patients were examined with myelography and/or CT af

Passive resistive torque of the plantar flexors following eccentric loading as assessed by isokinetic dynamometry

Isokinetic dynamometers may provide a useful means of measuring muscle stiffness resulting from eccentric exercise because they can measure torque from computer-controlled passive movements of joints (passive resistive torque; PRT). In this study, a Biodex measured increased ankle PRT (52%; p < .001) following heel drop exercise in nine young women. Therefore, isokinetic dynamometers can provide a

A BEAST for prowling in trees

When searching for convolutional codes and tailbiting codes of high complexity it is of vital importance to use fast algorithms for computing their weight spectra, which corresponds to finding low-weight paths in their code trellises. This can be efficiently done by a combined search in both forward and backward code trees. A bidirectional efficient algorithm for searching such code trees (BEAST)

Det ideologiska landskapet

The present work is one of nine parts making up the archaeological project The Öresund Fixed Link. The book begins with an account of all the features and artefacts that are considered to have belonged to the ideological sphere within the project. The focus is on two sites, one located on the coast, the other in the outer hummocky landscape. As regards remains on the coast, this work concentrates

Evidence-based recommendations or "Show me the patients selected and I will tell you the results"

Modern treatment decision making in medicine is recommended to be evidence based. In order to have a high grade of evidence, the studies should have sufficient power, be randomized and double blinded. Moreover, the evaluation parameters should be solid and reproducible. While there is a lot focus on primary study design much less is focused on patient eligibility and to what extent the patients in
