Investigators: Ján Zelinka, Peter Kaľavský A new subsystem for long-term multi-channel measurement, monitoring and simultaneous recording of measured biological signals was included in the software of the ProCardio 8 system. It is written in C ++ and uses a parallel processing technique that decomposes running tasks into parallel executed modules working in assigned threads. Individual…

(Investigators: J. Přibil, I. Frollo, D. Gogola, T. Dermek) During scanning in a magnetic resonance (NMR) tomograph, mechanical vibrations occur due to the function of the coils of the gradient system and acoustic noise is subsequently generated. This is a source of interference, especially in 3-D imaging – an increase in background noise and a…

(Investigators M. Hain, J. Bartl, V. Jacko) The results of the research of the Department of Optoelectronic Measurement Methods were applied in cooperation with the restorers of the Levoča Regional Restoration Studio during a non-destructive physical survey of eight Gothic panel paintings of the Altar of the Four Sts. John of the Roman Catholic Church…

(Investigators: V. Juráš, P. Szomolányi, I. Frollo) Although magnetic resonance imaging is currently considered the most accurate method for investigating cartilage damage, morphological imaging is often not sufficient to determine the degree of damage, nor does it detect early stages of degeneration, which are manifested solely by changes in the internal structure of cartilage. Quantitative…

(Investigators: A. Krakovská, F. Hanzely) The data that is the subject of causal analysis is often in the form of time series. In such cases, we usually reach for a standard Granger causality test. However, it is based on autoregressive models and can only be successfully used with stochastic, linearly interconnected systems. The method of…

(Investigators: J. Švehlíková, J. Zelinka, L. Bachárová, M. Tyšler) Using a computer model of the ventricles, we simulated and visualized the spread of the activation front in the heart chambers at normal rate, in cases of local slowing of the activation queue, thickening of the left ventricular wall and a combination of both factors present…

(Investigator: M. Škrátek) Biodegradable polymer nanocomposites represent a promising group of plastics usable for various bio- and enviro-friendly applications, such as drug carriers or biological plastics with shape memory. Polymers are generally electrically non-conductive and non-magnetic materials. Natural Halloyzite nanotubes (HNT) modified with iron oxide nanoparticles were used to improve the mechanical properties of the…

(Investigators: L. Valkovič, I. Frollo) Cardiovascular disease, obesity and diabetes are very often accompanied by changes in the energy metabolism of skeletal muscle. Therefore, modern medicine is placing increasing emphasis on research into new non-invasive methods for measuring energy metabolism. In line with this trend, new methodologies for determining oxidative metabolism using static and dynamic…

(Investigators: P. Kaľavský, M. Potse, S. Pezzuto, M. Tyšler) A method for computationally fast simulation of electrical activation of an anisotropic model of the heart based on eikonal equations was proposed. The method was implemented in the parallel programming language CUDA and supports massive parallel computations on graphics processors (GPU). The computational speed of the…

(Investigator: M. Hain) In the European project COST “Color and Space in Cultural Heritage” (researchers and color in cultural heritage), the researchers from ÚM SAS in In 2016, they actively participated in the work of the WG2 working group and the solution of the “Roman silver coins” study. X-ray microtomographic methods for analysis, testing and…
