Soft-tissues image processing: comparison of traditional segmentation methods with 2D active contour methods
(De Gruyter Open, 2012-07-31)
The paper deals with modern methods of image processing, especially image segmentation, classification and evaluation of parameters. It is focused primarily on processing medical images of soft tissues obtained by magnetic ...
Testing an Impedance Non-destructive Method to Evaluate Steel-Fiber Concrete Samples
(Institute of Measurement Science of Slovak Academy of Sciences, 2018-03-01)
The paper discusses tests related to the evaluation of the density and orientation of fibers in a composite material. Compared to the approaches used to date, the proposed technique is based on the evaluation of the ...
A Real Model of a Micro-Grid to Improve Network Stability
(MDPI, 2017-07-30)
This paper discusses the smart energy model of a smart grid using a significant share of renewable energy sources combined with intelligent control that processes information from a smart metering subsystem. An algorithm ...
GPU-Accelerated Reconstruction of T2 Maps in Magnetic Resonance Imaging
(De Gruyter Open, 2015-08-12)
The main tissue parameters targeted by MR tomography include, among others, relaxation times T1 and T2. This paper focuses on the computation of the relaxation time T2 measured with the Spin Echo method, where the sensing ...
Measuring Light Air Ions in a Speleotherapeutic Cave
(Institute of Measurement Science, Slovak Academy of Sciences, 2017-01-25)
The paper deals with a methodology proposed for measuring the concentration of air ions in the environment of speleotherapeutic caves, and with the implementation of the AK-UTEE-v2 ionmeter. Speleotherapy, in the context ...
Characterization of the Embryogenic Tissue of the Norway Spruce Including a Transition Layer between the Tissue and the Culture Medium by Magnetic Resonance Imaging
(De Gruyter Open, 2017-02-25)
The paper describes the visualization of the cells (ESEs) and mucilage (ECMSN) in an embryogenic tissue via magnetic resonance imaging (MRI) relaxometry measurement combined with the subsequent multi-parametric segmentation. ...
MRI-Based Visualization of the Relaxation Times of Early Somatic Embryos
(De Gruyter, 2016-04-15)
The large set of scientific activities supported by MRI includes, among others, the research of water and mineral compounds transported within a plant, the investigation of cellular processes, and the examination of the ...
The Effect of a Spiral Gradient Magnetic Field on the Ionic Conductivity of Water
(MDPI, 2017-09-02)
We discuss the experimental verification of changes in the structure of a liquid water sample inserted in a special spiral “gradient” magnetic field. The magnetic flux components are characterized by a high degree of ...
A Non-Destructive Impedance Method Using Resonance to Evaluate the Concentration of Steel Fibers in Concrete
(De Gruyter, 2018-10-08)
Steel-fiber reinforced concrete is a composite material characterized by outstanding tensile properties and resistance to cracking. The concrete, however, exhibits such characteristics only on the condition that the steel ...
A Sensor System for Detecting and Localizing Partial Discharges in Power Transformers with Improved Immunity to Interferences
(MDPI, 2019-02-22)
The paper reports on the solution, principles, and application results related to a system for diagnosing main transformers in power plants via the radiofrequency method. The subject of the diagnostics is the occurrence ...
