At present, accessing and processing Earth Observation (EO) data on different cloud platforms requires users to exercise distinct communication strategies as each backend platform is designed differently. The openEO API (Application Programming Interface) standardises EO-related contracts between local clients (R, Python, JavaScript) service providers regarding access processing, simplifying their direct comparability. Independent of the providers’ storage system, mimics functionalities a...
Cardiogenic shock after acute myocardial infarction is an indication for emergent coronary artery bypass grafting in patients not amenable to percutaneous intervention. Our study aimed evaluate and identify risk factors early long-term outcomes such patients.A total of 508 who underwent cardiogenic complicating between January 2000 June 2014 were divided into 3 time cohorts: 2004 (n=204), 2005 2009 (n=166), 2010 (n=138). Predictors in-hospital mortality each cohort all identified by logistic...
Abstract The unprecedented and continuously growing volume of Earth Observation (EO) geospatial data has necessitated a paradigm change where compute is collocated with the archives in public clouds. However, as no single cloud platform can host all this data, federated processing solutions that work across multiple platforms are becoming increasingly relevant. A community-based approach to started using openEO, common Application Programming Interface (API) set well-defined processes...
Reduction of station pressure to mean sea level (MSL) is a difficult procedure. In general, the temperature structure fictitious air column between height and MSL not known has be estimated somehow. Normally, reduced only for stations with relatively low elevations above (ASL). At higher stations, usually converted closest standard surface. United States, however, as high 2000 m ASL. order reduce amplitude annual variation at situated 305 ASL (hereinafter referred “plateau stations”),...
Meso-scale models are increasingly used for estimating wind resources turbine siting. In this study, we investigate how the Weather Research and Forecasting (WRF) model performs using standard settings in two different planetary boundary layer schemes a forested landscape performance is changed when enhancing roughness by factor four one of schemes. The simulations were evaluated data from 138 m tall mast southeastern Sweden, where an experiment with six sonic anemometers meteorological...
Knowledge of cardiac electro-mechanical phenomena can be achieved by mathematical modeling and numerical simulation. Topic the work is assembly parameterization an model human myocytes. The integrates electrophysiological a tension development model. This integration additional adaptation to studies myocardium necessitated re-parameterization several components, which was performed applying different optimization techniques. Results characteristics are illustrated experiments. Simulations...
Mathematical models of cardiac anatomy and physics provide information, which help to understand structure behavior the heart. Miscellaneous phenomena can only be adequately described by combination representing different aspects or levels detail. Coupling these necessitates definition appropriate interfaces. Adequateness efficiency interfaces is crucial for efficient application combined models. In this work an integrated model presented consisting several interconnected The allows...
The heart's pumping function is dependent on the vitality of heart muscle, which mostly composed contractile cells, so-called myocytes. orientation these myocytes throughout muscle results in a unique profile contraction allowing process to be possible. Knowledge arrangement and physiological properties cells permits creation realistic computer models. Simulations with models can used e. g. for pre-interventional planning educational purposes. utilized elastomechanical model based spring...
The classic tool of assessing learning progress are written tests and assignments. In large groups students the workload often does not allow in depth evaluation during course. Thus our aim was to modify course include active methods student centered teaching. We changed structure only slightly established new assessment like minute papers, short tests, mini-projects a group project at end semester. focus monitor so that problematic issues could be addressed immediately. year before changes...
Computer models of the heart lead to a better understanding physiological and physical processes underlying each beat. Various exist for simulating electrophysiology, excitation propagation, force development deformation. Simulations can be used support medical doctors in diagnostics, surgery planning serve educational purposes. This work focuses on mechanical aspects heart. with electrophysiological, propagation were carried out. Force was utilized as input model. A hybrid myocardial...
Suction performance, pressure rise, and efficiency for four different inducers are examined with computational fluid dynamics (CFD) simulations experiments performed 18,000 rpm 24,000 rpm. The studies originate from a research project that includes the construction of new test bench in order to judge design inducers. This allows conduct rotational speed up 40,000 high ranges 0.1 bar 40 water as working fluid. Experimental results used evaluate accuracy gain better understanding parameter....
<p>The growing data stream from Earth Observation (EO) satellites has advanced scientific knowledge about the environmental status of planet earth and enabled detailed monitoring services. The openEO API developed in Horizon 2020 project (2017–2020, see https://openeo.org/) demonstrated that large-scale EO processing needs can be expressed as a common set analytic operators which are implemented many GIS software or image analysis products. Platform service...
