Denna avhandling undersöker utvecklingen av en tio års engagemang av tillgänglighet i utemiljön. Denna undersöks från två perspektiv; samhällets utmaning och användarens uppfattning. Äldre personer och personer med funktionshinder ska ha lika möjligheter att använda transportsystemet som andra människor. Deras tillgång till transportsystemet är dock ofta begränsad på grund av fysiska hinder i utemIn an inaccessible outdoor environment, older people and people with disabilities can experience environmental barriers. The environmental barriers can restrict them and their abilities to walk. Environmental barriers can be avoided by designing the outdoor environment to meet the needs of older people and people with disabilities. This thesis focuses on accessibility in Sweden from two perspectiv

Quantitative in-cylinder measurements of soot volume fraction in a single-cylinder HSDI Diesel engine, based on a VOLVO D5, has been carried out using the laser-induced incandescence (LII) technique using laser excitation at 1064 nm and an ICCD camera with prompt gate detection. Quantitative data was obtained by relating the LII signal response from the engine to that from a calibration flame. The

A new algorithm for clustering is presented --- the Distributed Clustering Algorithm (DCA). It is designed to be incremental and to work in a real-time situation, thus making it suitable for robotics and in models of concept formation. The DCA starts with one cluster (or rather prototype at the center of the cluster), successively adding prototypes and distributing them according to data density u

Twenty-one placentae from type I (insulin-dependent) pregnant diabetic patients, treated with continuous subcutaneous insulin infusion (CSII), were studied morphologically. Despite a near-optimal blood glucose control the placental changes were identical to those previously reported in diabetic pregnancy. The most frequently observed lesion was that of relative placental immaturity; this, when ext

Sheet-metal forming involves a complex strain distribution over the part. The strains consist of tension, compression, and a mix of both. A geometry has been developed, the X-Die, in order to gain insight into the strain behavior of different materials. The X-Die enables strain paths far into the tension/compression region, thus creating the possibility to extend the experimental base both for def

In this paper, we present a controller synthesis algorithm for a decentralized control problem. We consider an architecture in which there are two interconnected linear subsystems. Both controllers seek to optimize a global quadratic cost, despite having access to different subsets of the available measurements. Many special cases of this problem have previously been solved, most notably the state

Cerebellar learning requires context information from mossy fibers and a teaching signal through the climbing fibers from the inferior olive. Although the inferior olive fires in bursts, virtually all studies have used a teaching signal consisting of a single pulse. Following a number of failed attempts to induce cerebellar learning in decerebrate ferrets with a nonburst signal, we tested the effe

We study the short-run and long-run economic impact of one of the largest losses that an individual can face; the death of a child. We utilise unique registers on the entire Swedish population, combining information on the date and cause of death with parental outcomes. We exploit the longitudinal dimension of the data and deal with several selection issues. Losing a child has adverse effects on l

Introduction. In recent years, there has been a growing interest in ethnographic research within the field of library and Information studies. Although ethnography has been used by information researchers for studying a wide variety of phenomena, discussions concerning methodological developments and directions, as well as ethnography’s wider applicability within the field are rare. Our intent is

Abstract in Spanish Los rituales indígenas acompañaron a Evo Morales a través de sus primeros años como presidente de Bolivia. El oficio y las prácticas rituales del curandero y sabio aymara, el yatiri, están pasando por interesantes transformaciones, entrando a espacios políticos donde no solían estar presentes. ¿Pero cuál es realmente el papel que juegan el conocimiento terapéutico y la práctica

This paper proposes a novel non-parametric estimator for spectroscopic echo-train signals, termed ETCAPA, to be used as a robust and reliable first-approach-technique for new, unknown, or partly disturbed substances. Exploiting the complete echo structure for the signal of interest, the method reliably estimates all parameters of interest, enabling initial estimates for the identification procedur
