Opis:: Abstract: The paper presents a new measurement method for checkweighers, where the measurement result is obtained by solving a simple optimization problem. The method assumes that the mass of constant geometry and a small masses spread is measured. The measurement accuracy changes as a function of noise-eliminating low-pass filter frequency was investigated. The state of knowledge about the filtration of checkweigher signal is also summarized.

Opis:: This paper presents an application of magnetovision based measurements to develop a method for passive detection of dangerous ferromagnetic objects. Scanning system was designed and built to study the magnetic field vector distributions. The measurements of the Earth's field disturbances caused by ferromagnetic objects were carried out. The ability for passive detection of selected dangerous objects was demonstrated. Further data processing allowed for determining the (x,y) coordinates of the object relative to the plane of measurement, and even the possibility of calculating the distance from the object. The results obtained indicate that it is possible to detect and determine the location of dangerous ferromagnetic objects. This opens the new way to use magnetovision in public security systems, in particular for the detection of dangerous objects by police and sapper robots.

Opis:: The paper presents the results of modelling the influence of magnetizing field frequency on the magnetic characteristics of $Fe_{40}Ni_{38}Mo_4B_{18}$ amorphous alloy in as-quenched state. An extension for the Jiles-Atherton model was applied and changes of the parameter k during the magnetization process were considered. On the base of the experiment, the parameters of the Jiles-Atherton model were calculated for experimental hysteresis loop. Evolutionary strategies, together with the gradient optimisation method, were used. Moreover, the changes of parameters c and a as the function of frequency of magnetizing field were also taken into consideration. Finally, the high conformity between the experimental and modelling results was achieved. This high conformity indicates that the results both create new possibilities in modelling of properties of inductive components based on the amorphous alloys, as well as extend the possibility of quantitative description of magnetization process.

Opis:: Possibilities of the modeling of the flux density distribution in thin films are significantly limited using the finite elements method due to the fast increase of the number of tetrahedral elementary cells with reduction of the thickness. For this reason, method of the moments is very important alternative for finite elements method in the case of thin layers, where layer's thickness should be considered. Method of the moments overcomes this barrier, due to the possibility of operation on uniform grids with limited number of cells. Moreover, in opposite to the finite elements method, the method of the moments requires solving of the well defined linear equations, instead of the set of ill-posed differential equations. Paper presents the generalization of the method of the moments for thin layers with given thickness. Layers are defined as the 2D rectangular grids. Within the generalization, four key equations describing the influence of rectangular cell's border on the magnetization of cells are stated. On the base of these dependences, the set of 2NM linear equations was determined, where N and M are the numbers of rectangular cells in the rows and columns of regular grid. Finally, the set of linear equations is solved and magnetic flux density distribution in the thin layer is calculated.

Opis:: Paper presents utilized innovative setup for eddy current tomography and possibility of its utilization in testing oxide materials such as ferrites. Previously reported tests concerned materials with high conductivity which is the most typical usage of eddy current tests. Described tomography setup is designed for testing axisymmetric objects thus typical ferrite ring was selected for exemplary testing. Tests were conducted on ring in original state. Afterwards reference defect was created on element and measurements were repeated. Significant difference between tests results were observed, thus potential for utilization in controlling of ferrite rings manufacturing process was confirmed. Finite element method simulations were applied in order to confirm the measurement results. Calculations were conducted in open-source finite element method software, which solves the Maxwell equations in the A-V form. Modelling results confirm possibility of finite element method-based inverse tomography transformation.

Opis:: Recent development of SPICE, FEM and MoM software often requires the fast and reliable description of BH saturation magnetization curve. In spite of the fact that physical models of BH saturation curve are very sophisticated, for technical purposes, such curve may be modelled by simplified equations. Paper presents the quantitative assessment of the quality of four technical models of BH saturation magnetization curve performed for four modern magnetic materials: constructional corrosion resistant steel, Mn-Zn ferrite, amorphous alloy with perpendicular anisotropy as well as Finemet-type nanocrystalline magnetic material. Presented results confirm reliability of the model as well as indicate that high-speed calculation may be done using arctangent function.

Opis:: The following paper presents the results of modelling of the magnetic characteristics of isotropic (Ni-Zn ferrite) and anisotropic material ($Fe_{40}Ni_{38}Mo_4B_{18}$ amorphous alloy in as quenched state), both useful for sensor applications. For the modelling an extended Jiles-Atherton model was used. Extension of the model connects model's parameter k, describing average energy required to break pinning site, with magnetic state of the material. Such extension of the model is reasonable from the physical point of view. Good agreement between experimental data and modelling confirms that the extended Jiles-Atherton model creates the possibility of modelling of magnetic characteristics of both isotropic and anisotropic magnetic cores.

Opis:: Recent traceability requirements create necessity of organization of the food production process in the completely new way. This way of production organization is typical rather for large industry, than for traditional way of work at the rural areas. This fact generates tensions as well as resistance of the farmers, especially farmers working in traditional way. This paper presents new ideas of industrial application of automation standards and methodologies for reliable, robust and user-friendly food traceability system. Due to the high level of automation and application of industrial IT solutions together with multimodal data transmission, presented traceability system can be implemented in traditional food production farms and operated intuitively by personnel without specialized training. As a result application of presented system will signifi-cantly reduce tensions and resistance connected with implementation of new technologies in tradi-tional food production farms.
