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 ...
The Effect of a Spiral Gradient Magnetic Field on the Ionic Conductivity of Water
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
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 ...
The Evaluation of Noise Spectroscopy Tests
The paper discusses mathematical tools to evaluate novel noise spectroscopy based analysis and describes, via physical similarity, the mathematical models expressing the quantitative character of the modeled task. Using ...
