We investigate the potential of using previewed wind speed measurements for damping wind turbine fore-aft tower oscillations. Using recent results on continuous-time H2 preview control, we develop a numerically efficient framework for the feedforward controller synthesis. One of the major benefits of the proposed framework is that it allows us to account for measurement distortion. This results in

Objective: Systemic lupus erythematosus (SLE) is a complex disease with variable presentations, course and prognosis. We sought to develop evidence-based recommendations addressing the major issues in the management of SLE. Methods: The EULAR Task Force on SLE comprised 19 specialists and a clinical epidemiologist. Key questions for the management of SLE were compiled using the Delphi technique. A

Background: 2,5-hexanedione (2,5-HD) is the main neurotoxic metabolite of methyl-n-butyl ketone (MBK) and n-hexane, and known to cause polyneuropathy. The aim of our study was to compare the urinary levels of 2,5-HD between cases with cryptogenic polyneuropathy and the general Swedish population, and to elucidate the role of certain external factors. Methods: Morning urine samples were collected f

Aim: To assess the development of preterm infants from 40 weeks gestational age to 18 months corrected age in order to identify early predictors of later development. Methods: Fifty-one infants were involved. Infant development was assessed at 40 and 44 weeks gestational age with the Brazelton Neonatal Behavioral Assessment Scale and a Self-Regulation Scale and at 3, 6, 10, 18 months corrected age

Within the heavy baryon chiral perturbation theory approach, we have studied the leading logarithm behavior of the nucleon mass up to four-loop order exactly and we present some results up to six-loop order as well as an all-order conjecture. The same methods allow to calculate the main logarithm multiplying the terms with fractional powers of the quark mass. We calculate thus the coefficients of

Sammanfattning I Skåne odlas 34 500 ha sockerbetor för sockerutvinning och i Sverige 36 000 ha (Jordbruksstatistik årsbok 2014). Vid insamling och rötning av blasten från betorna i Skåne skulle drygt 200 GWh biogas kunna produceras per år och driva minst 19 000 bilar eller 1000 bussar. Men idag lämnas den i fält. Tidigare studier har visat att betblast från sockerproduktion är på gränsen till löns

Popular Abstract in Swedish Diabetes, i alla dess olika former, är en allvarlig sjukdom. Typ 1 diabetes är av autoimmun härkomst, då kroppen eget immunförsvaret attackerar och förstör β-cellerna i bukspottkörteln. Dessa celler producerar insulin som hjälper kolhydraterna i maten vi äter att komma kroppens celler till godo. Sverige har världens näst högsta antal nya insjuknanden, bara Finland har fThe role of miRNAs in pancreatic islets and β-cell function and in the development of diabetes in human and rodents have been investigated in this thesis. Dicer1 was specifically deleted in vivo in pancreatic β-cells under the RIP-promoter in mice. The results show that disruption of miRNAprocessing in mouse pancreatic β-cells, while compatible with β-cell development, leads to defective insulin-s

Surface roughness is a commonly used criterion for characterization of surface quality in a machining operation. In the study of micro-scale mechanical properties of machined surface and cutting tool with nanoindentation, prefect surface finish on the test specimen is often required for the reliable result. However, the prefect surface finish is often difficult to obtain from the machining operati

Computer vision is today a wide research area including topics like robot vision, image analysis, pattern recognition, medical imaging and geometric reconstruction problems. Over the past decades there has been a rapid development in understanding and modeling different computer vision applications. Even though much work has been devoted to modelling different problems, less work has been spent on

The COST/IWA Benchmark Simulation Model No 1 (BSM1) has been available for almost a decade. Its primary purpose has been to create a platform for control strategy benchmarking of activated sludge processes. The fact that the research work related to the benchmark simulation models has resulted in more than 300 publications worldwide demonstrates the interest in and need of such tools within the re

Bertil Ohlin was a most active commentator on current economic events in the interwar period, combining his academic work with a journalistic output of an impressive scale. He published more than a thousand newspaper articles in the 1920s and 1930s, more than any other professor in economics in Sweden. Here we have collected 10 articles by Ohlin, translated from Swedish and originally published i

Emissions and in-cylinder pressure traces are used to compare the relative importance of soot formation and soot oxidation in a heavy-duty diesel engine. The equivalence ratio at the lift-off length is estimated with an empirical correlation and an idealized model of diesel spray. No correlation is found between the equivalence ratio at lift-off and the soot emissions. This confirms that trends in

Understanding how learning occurs, and what improves or impedes the learning process is of importance to academicians and practitioners; however, empirical research on validating learning curves is sparse. This paper contributes to this line of research by collecting and analyzing CAD (computer-aided design) procedural and cognitive performance data for novice trainees during 16-weeks of training.
