In this paper a controller reduction method which preserves closed loop stability is described. A Lyapunov inequality based sufficient condition is proposed in the search of the reduced controller. The reduced controller leads to a stable closed loop system with guaranteed approximation quality. Furthermore, the proposed problem can be formulated as a matrix approximation problem which can be solv

In 1973, the Swedish Centre party managed to attract 25.1 per cent of the votes in that year’s election. A quarter of a century later the once agrarian party hovered precariously close to the four per cent election threshold. During the long and unbroken decline, the party was a member of the centre-right bloc – yet was intermittently drawn to the Social Democrats. Throughout, it retained a strong

High-resolution near-edge X-ray absorption fine structure (NEXAFS) measurements at the As M-edge, F K-edge and S L-edge of the Fabre salt (TMTTF)(2)AsF6 were performed from room temperature (RT) to 90 K, allowing to reach the charge localization regime below T-rho approximate to 230 K and to cross the charge ordering (CO) transition at T-CO approximate to 102 K. The F K-edge and S L-edge spectra e

The shear-induced transformations between oriented planar lamellae and a state of closely packed multilamellar vesicles (MLVs) in a lyotropic nonionic surfactant model system were studied by the combination of nuclear magnetic resonance (NMR) spectroscopy and diffusometry with magnetic resonance imaging (MRI). H-2 NMR imaging confirmed the discontinuous nature of the transition from onions to plan

Background: Medical treatment of hypertension is not always sufficient to achieve blood pressure control. Despite this, previous studies on supplementary therapies, such as yoga, are relatively few. We investigated the effects of two yoga interventions on blood pressure and quality of life in patients in primary health care diagnosed with hypertension. Methods: Adult patients (age 20-80 years) wit

NMR has contributed greatly to our current understanding of self-association, phase behaviour, and molecular dynamics in aqueous systems of oligo(ethylene oxide) mono-alkyl ether (CmEn) nonionic surfactants, which are extensively used in both basic scientific studies and technical applications as emulsifying agents and detergents. This review provides a comprehensive but concise overview of the va

A collection of 30 papers from the international conference "Locus Celebris - The Church, Monastery and Manor of Dalby" in April 2010.

A three-day workshop was held in Lund, Sweden, from March 25 to 27, 2015, with a focus on timing modes for low-emittance storage rings. The MAX IV Laboratory, currently under construction in Lund, will provide a 1.5 GeV storage ring for soft X-rays and a 3 GeV storage ring with an ultralow emittance down to 0.2 nm rad for hard X-rays [1]. Both rings are designed to operate with a uniform multibunc

Background: Work disability is common among women with fibromyalgia (FM). The aim of the study was to investigate what health problems and work-related difficulties lead to hinders for continued work among women with FM. Methods: A qualitative interview study. Twenty-seven gainfully employed women with FM participated in five focus group interviews. Their median age was 52 years, ranging from 33 t

Purpose - The purpose of this study is to analyze the relationship between police investigators' decision-making styles, degree of judgmental self-doubt and work conditions, on the one hand, and their wellbeing, stress, burnout tendency and sleep quality, on the other. Design/methodology/approach - The study concerns investigative police officers (n = 203). Decision-making styles were measured by

The price of fish depends on quality attributes such as size and freshness. In turn, quality attributes are related to fishery management. This article presents a hedonic analysis where attribute prices of size and quality ratings are estimated for the Swedish Baltic cod fishery. Using information from 5,307 landing days, hedonic inverse demand functions are estimated with a random coefficient (RC

Aim and objectives. To assess the psychometric characteristics of the Icelandic European Organisation for Research and Treatment of Cancer IN-PATSAT32 (EORTC IN-PATSAT32) version and to compare satisfaction with care between gender and different age groups. Background. The majority of patients with cancer receive either chemotherapy or radiotherapy on an outpatient basis. There is a need to evalua

Sexual selection may drive speciation, but most research focuses on pre-copulatory sexual selection, overlooking post-copulatory processes. Post-copulatory sexual selection in allopatric populations could drive divergence in post-copulatory pre-zygotic (PCPZ) phenotypes, limiting gene flow upon secondary contact. Here, we performed in vitro experiments examining one potential PCPZ barrier between

The greater part of Western Esoterism holds beliefs in five important matrices. This branch of esoterism, rooted in a Hermetic milieu, is labelled dialectical esoterism because of the dialectical relationship between the ‘lower’ (man, earth) and the ‘higher’ (heaven, the divine, God). These five matrices are: I: Purpose (pronoia), rather than karma or sin. II: The dialectical relationship betwee

The potential of Fe-V-oxide catalysts for use in methanol oxidation is explored. Our results show that although FeVO4 is active and selective for formaldehyde formation, it is not completely stable towards volatilization under reaction conditions. Attempts to stabilize Fe-V-oxide were made using titania, alumina and silica supports. However, we observe that although some stabilization is achieved

The value of IT adoption has been and still is a crucial question for the decision on IT adoption. In this paper we suggest a research model that aims at defining the integrative value of adoption of Enterprise Resource Planning (ERP) and Customer Relationship Management (CRM) systems. The integrative value is described from the Resource Based View of the firm (RBV) and will be measured as impact

Objectives: Uncomplicated acute type B aortic dissection (AD) treated conservatively has a 10% 30-day mortality and up to 25% need intervention within 4 years. In complicated AD, stent grafts have been encouraging. The aim of the present prospective randomised trial was to compare best medical treatment (BMT) with BMT and Gore TAG stent graft in patients with uncomplicated AD. The primary endpoint
