Opis:
The paper presents an eddy current tomography setup with high spatial resolution and high accuracy of measurements of signal on detection coil. In proposed solution both amplitude as well as phase shift are measured, which gives the possibility of calculation of spatial distribution of both permeability and resistivity of tested element. As a result, presented setup creates possibility of effective detection of discontinuities in cylindrical elements, which opens new possibilities for industrial applications of eddy current tomography.

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:
This paper presents the implementation of the extended Preisach model for fluxgate sensor characteristics modeling. The developed model enables the optimization of fluxgate sensor parameters for a given core material. Model consists of two parts. The first one describes magnetic characteristics of the core, while the second part calculates output signal according to sensor dimensions and electric circuit parameters. The model is easy to adapt for modeling of other devices with magnetic cores. It can be used instead of costly and time consuming prototype testing.

This paper presents results of investigation of stress influence on magnetic characteristics of ferrite ring cores for inductive electronics components. Ring-shaped cores were made of Ni-Zn ferrite designed for anti-lung filter cores. The results of the study indicate a significant impact of external forces stresses on the magnetic properties of ferrite cores. Such changes are very important due to their influence on the correct operation of the induction components.

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 article analyses the condition of organic farming in Poland on the basis of the data published by the Agricultural and Food Quality Inspection, the Central Statistical Office and available literature sources. The aim of the study was to assess the condition and prospects for the development of organic produc-tion in Poland. The results of the analysis indicate that there is a growing demand for organic products among consumers, which may contribute to the development of organic farming and an in-crease in the processing of organic products. However, in recent years, a decline in the number of organic farms and the total area of organic farming has been observed. Fodder plants, cereals as well as meadows and pastures are predominant in the structure of crops. Orchards, berries and vegetable cultivation as well as industrial crops are of lesser importance. Poultry, sheep and dairy cattle are predominant in organic livestock farming, whereas goats and cattle intended for meat account for a lower percentage. Among the organic agricultural products milk and dairy products are produced in the greatest quantities.

Opis:
The purpose of this paper is to present the idea of using cloud computing and RFID identification system in a car park. The presented system is able to navigate a vehicle to a parking space in the shortest time and to reduce traffic jams thanks to RFID transponders built in parking spaces. The system uses a combination of autonomous and master control to navigate the vehicles. It can execute different traffic scenarios depending on the availability of park spaces and navigate each vehicle using an autonomous route. A dedicated software algorithm for the navigation was also proposed and developed. The system utilizes an external cloud-based database of RFID transponders. A prototype model of car park equipped with RFID technology was designed and built to demonstrate the presented idea.

Opis:
The purpose of this article is to present image management and unattended systems in research and teaching laboratories. Both types of laboratories are specific from the point of view of IT personnel. In this work environment, unlike computers used for example in offices, frequent and advanced changes in configurations and settings are necessary.
