Modeling and Control of Stiff Robots for Flexible Manufacturing

Popular Abstract in Swedish Made in China - På hur många av dina barns leksaker står det? Produktionen inom många sektorer flyttas från Europa till länder där arbetskraften är billigare. Forskningen i avhandlingen "Modeling and Control of Stiff Robots for Flexible Manufacturing" ska hjälpa europeiska småföretag att bli mer konkurrenskraftiga och samtidigt underlätta för arbetarna. Högt ljud frånTo survive on a global market, small and medium size enterprises (SMEs) require affordable and competitive industrial automation for high quality flexible manufacturing. This thesis contributes to the development of robot concepts that fit the needs of SMEs. A major part of the thesis deals with the modeling of the three degree-of-freedom (DOF) Gantry-Tau parallel kinematic robot, which has the po

Effects of a training program after surgically treated ankle fracture: a prospective randomised controlled trial

Background: Despite conflicting results after surgically treated ankle fractures few studies have evaluated the effects of different types of training programs performed after plaster removal. The aim of this study was to evaluate the effects of a 12-week standardised but individually suited training program ( training group) versus usual care ( control group) after plaster removal in adults with

Cost-Utility Analysis of Glucagon-Like Peptide-1 Agonists Compared with Dipeptidyl Peptidase-4 Inhibitors or Neutral Protamine Hagedorn Basal Insulin as Add-On to Metformin in Type 2 Diabetes in Sweden.

This study aimed to assess the costs and benefits of three alternative second-line treatment strategies for Swedish patients with type 2 diabetes mellitus (T2DM) who fail to reach glycated hemoglobin (HbA1c) ≤ 7% with metformin treatment alone: glucagon-like peptide-1 (GLP-1) receptor agonists, dipeptidyl peptidase-4 (DPP-4) inhibitors, and neutral protamine Hagedorn (NPH) insulin.

Computer-aided diagnosis system outperforms scoring analysis in myocardial perfusion imaging

The aim of this myocardial perfusion imaging (MPI) study was to compare the diagnostic performance of two computer-aided diagnosis (CAD) systems, EXINI Heart(TM) (EXINI), and PERFEXTM (PERFEX) Emory Cardiac Toolbox (ECT), and the summed stress score (SSS) values from both software packages. We studied 1,052 consecutive patients who underwent 2-day stress/rest Tc-99m-sestamibi MPI studies. The refe

The production and turnover of extramatrical mycelium of ectomycorrhizal fungi in forest soils: role in carbon cycling

There is growing evidence of the importance of extramatrical mycelium (EMM) of mycorrhizal fungi in carbon (C) cycling in ecosystems. However, our understanding has until recently been mainly based on laboratory experiments, and knowledge of such basic parameters as variations in mycelial production, standing biomass and turnover as well as the regulatory mechanisms behind such variations in fores

DNA C-values of 20 invasive alien species and 3 native species in South China.

Cultivated fields and forests in South China are experiencing serious damage due to invasive alien plants. We investigated the relation between DNA C-values and invasiveness. The DNA C-values of 23 species ranged from 0.39 pg to 3.37 pg. Herbs, perennials and native species had higher mean DNA C-values than shrubs, annuals and invasive alien species. DNA C-values decreased with increasing invasive

Fish consumption and myocardial infarction: a second prospective biomarker study from northern Sweden

Background: A beneficial role of fish consumption on the risk of myocardial infarction (MI) has been reported and is mostly ascribed to n-3 (omega-3) fatty acids. However, fish also contains methylmercury, which may increase the risk of MI. Objective: The objective was to determine how fish consumption and erythrocyte concentrations of mercury (Ery-Hg) and selenium (Ery-Se) are related to the risk

Metabolic syndrome and rare gynecological cancers in the Metabolic syndrome and Cancer project (Me-Can)

Background: Risk factors for rare gynecological cancers are largely unknown. Initial research has indicated that the metabolic syndrome (MetS) or individual components could play a role. Materials and methods: The Metabolic syndrome and Cancer project cohort includes 288 834 women. During an average follow-up of 11 years, 82 vulvar, 26 vaginal and 43 other rare gynecological cancers were identifie

Biosensor Monitoring of Microbial Treatment of Wastewater from Nonylphenol Polyethoxylates under Flow-through Conditions

Biodegradation of nonylphenol polyethoxylates (NPEO) has been studied in laboratory column bioreactors with a polyethylene carrier on which destructor bacteria of Pseudomonas surface-active compounds were immobilized. To monitor the efficiency of microbial treatment of model wastewater, a biosensor based on the oxygen Clark electrode and destructor bacteria of NPEO from bioreactors was designed. T

Evaluation of methods to estimate production, biomass and turnover of ectomycorrhizal mycelium in forests soils - A review

Mycorrhizal fungi constitute a considerable sink for carbon in most ecosystems. This carbon is used for building extensive mycelial networks in the soil as well as for metabolic activity related to nutrient uptake. A number of methods have been developed recently to quantify production, standing biomass and turnover of extramatrical mycorrhizal mycelia (EMM) in the field. These methods include min

Rational design of HIV vaccines and microbicides: report of the EUROPRISE annual conference 2011

Europrise is a Network of Excellence supported by the European Commission within the 6th Framework programme from 2007 to 2012. The Network has involved over 50 institutions from 13 European countries together with 3 industrial partners and 6 African countries. The Network encompasses an integrated program of research, training, dissemination and advocacy within the field of HIV vaccines and micro

Genetic associations to germinal centre formation in primary Sjogren's syndrome

Background Primary Sjogren's syndrome (pSS) is an autoimmune rheumatic disease mainly characterised by focal mononuclear cell infiltration in the salivary and lacrimal glands, and by the symptoms xerostomia and keratoconjunctivitis sicca. Germinal centre-like structures (GC) are found in the minor salivary glands of approximately 25% of patients. In this study, we aimed to assess genetic variation

Woven convolutional graph codes with large free distances

Constructions of woven graph codes based on constituent convolutional codes are studied and examples of woven convolutional graph codes are presented. The existence of codes, satisfying the Costello lower bound on the free distance, within the random ensemble of woven graph codes based on s-partite, s-uniform hypergraphs, where s depends only on the code rate, is shown. Simulation results for Vite

Introducing Usability Testing in the Risk Management Process in Software Development

Human beings make errors and that is nothing that we can avoid completely. We can however lower the risk of people doing wrong in situations where, for example, medical devices are used. The overall objective of the research presented in this paper is to investigate how usability testing can contribute to software risk management process in the medical device domain. Experience has been collected

Timing of ophiolite obduction in the Grampian orogen

This study addresses the timing and pressure-temperature (P-T) conditions of ophiolite obduction, one of the proposed causes of the ca. 470 Ma Grampian orogeny of Scotland and Ireland. This event gave rise to the main structural and metamorphic characteristics of the Grampian terrane-the type area for Barrovian metamorphism, the cause of which remains enigmatic despite a century of research.

”The EU Administration of the divided Bosnian city of Mostar: Implications for EUs evolving peacebuilding approach

This article explores the EU’s efforts to reunify and reconstruct Mostar through the seminal experiment of EUAM (1994-1996), which combined peacebuilding with urban reconstruction in an innovative way. The aim is to identify lessons to be learned from the experiences of EUAM that can assist the EU to adjust its peacebuilding approach to better address post-conflict divides in cities where the EU c
