Opis:: Idea of the high-resolution eddy current tomography is presented. Proposed system gives possibility of testing cylinder-shaped elements made of both magnetic and non-magnetic materials. To validate the concept, the tomographic measurements are carried out on set of steel cylinders with non-magnetic copper inclusion. Measurements were done during both linear and rotational movement of the element. Achieved results indicate the high sensitivity of system, which creates possibility of its application for non-destructive testing of the elements made of ferromagnetic and non-magnetic materials.

Opis:: The following paper presents the results of the investigation on the influence of the torque on the magnetic characteristics of the Hitperm-type $Fe_{41.5}Co_{41.5}Cu_1Nb_3B_{13}$ alloy, in as-quenched and nanocrystalline state. The methodology of application of the torque to the ring-shaped core is also described. This methodology gives a possibility of achieving uniform shearing stresses in the core. The results indicate that shearing stress sensitivity of Hitperm-type alloys depends on the annealing and nanocrystallization process. This effect should be considered during the development of magnetoelastic torque sensors.

Opis:: Paper presents the new methodology of application of uniform torque to the ring-shaped magnetoelastic sensing elements. The results of investigation on the influence of a torsion on the magnetic properties of different amorphous Fe-based ring cores are also presented. The results of tests on Fe Si B amorphous alloy in as-cast and annealed state as well as Fe Nb Cu Si B nanocrystalline alloy indicate, that torque sensitivity is connected with both alloy composition and state on the alloy. Moreover the most sensitive is F amorphous alloy in annealed state. As a result this alloy is the most suitable as a core of magnetoelastic torque sensors.

Opis:: The paper presents determination of PID controller parameters for application of plasmatron powered plasma reactor designed and build in Industrial Research Institute for Automation and Measurements. Plasma reactor is the key element of the test setup, designed to research, processing and recovery of metals from waste of electric and electronic equipment, focusing on electronic printed circuit boards. Experiment was carried out with power of 36 kW. In experiment two temperatures were measured in two points of the reactor chamber, allowing verification of thermal response. Basing on identification of thermal parameters of the plasma reactor carried out in previous paper [7], the PID controller was chosen, as suitable to control second order inertia object. Parameters of used PID controlled were determined using MATLAB-Simulink toolbox. Calculated PID model was utilized for plasma reactor parameters control, allowing examination of energy saving by reducing of plasmatrons power, and stabilization of process parameters.

Opis:: In the paper the results of investigation on tensile stresses dependence of magnetoelastic characteristics of cores made of 13CrMo4-5 constructional steel are presented. In the investigation step-cooling test treated samples were used. The step-cooling test process is a type of heat treatment simulating effects of passing time and environmental conditions (temperature and stress) on the sample. In the paper the method of testing the influence of stresses on the magnetic characteristics is presented. Frame shaped samples ensured a closed magnetic circuit and homogeneous distribution of stress. It was found that step-cooling test does not significantly influence the magnetoelastic characteristics and the structure of the samples. On the other hand, then tensile stresses significantly change the magnetic characteristics of 13CrMo4-5 constructional steel. That confirms the possibility of using measurements based on the magnetoelastic effect in the stress assessment for industrial non destructing testing of steel constructions.

Opis:: Microwave devices are widely used in the industry and in the specialized laboratory analyses. Development of such devices requires the possibility of modeling of microwave energy distribution in the specific resonant chambers. Until now, such modeling was possible only with the use of commercial software or was limited to specific cases. The paper presents an open-source module for ELMER software for solving timeharmonic Maxwell’s equations, allowing modeling of microwave waveguide lines. Three test cases of different resonant chambers are investigated at 2.45 GHz frequency. Modeling results obtained from the open-source ELMER Vectorial Helmholtz module show that the application of this software can be effective in R&D works, enabling high-tech small and medium enterprises involvement in advanced microwave technology.

Opis:: The paper presents a novel method of measurements of tensile stress dependence of the magnetic characteristics of ring-shaped cores made of soft amorphous alloys. In the presented method, the uniform tensile stress was applied perpendicularly to the magnetizing field direction. Magnetoelastic core with closed magnetic circuit was fixed on the non-magnetic backings enabling the conversion of compressive force into tensile stresses as well as it enables the core to be winded by magnetizing and sensing windings. Magnetoelastic characteristics measured under tensile stress, for $Fe_{25}Ni_{55}Si_{10}B_{10}$ alloy annealed in temperature 350°C for 1 h, are presented in this paper. The presented results indicate high tensile stress sensitivity of $Fe_{25}Ni_{55}Si_{10}B_{10}$ alloy. Moreover, together with magnetoelastic characteristics for compressive stresses (presented previously in the literature), the describes results create possibility of further development of models of the magnetoelastic effects in amorphous alloys.

Opis:: Paper presents results of a discrete inverse tomography transformation on exemplary results from eddy current tomography setup. Eddy current phenomena is highly non-linear and measurement results are ill-posed function of distribution of physical properties of the matter (mostly electrical conductivity and magnetic permeability). Thus the inverse transformation (reconstruction of objects shape) is based on an optimization algorithm in which objects model is described as a discrete array. With the usage of Finite Element Method (FEM) tomography measurement process is reconstructed and modelling results are compared with the measurement.
