    Opis:
    Artykuł dotyczy problematyki kształcenia studentów wyższych uczelni pedagogicznych w kontekście rozwoju i modernizacji systemu szkolnictwa wyższego. Podstawowym czynnikiem wymuszających zmiany są procesy związane z globalizacją, takie jak zmiana stylu życia związana ze wzrostem tempa interakcji społecznej pod wpływem nowych technologii, migracją ludności, transferem usług oraz unifikacja kulturową wynikającą z kopiowania modelów konsumpcji i nieograniczonego rozprzestrzeniania idei. Wobec tych gwałtownie przebiegających zmian, jednym z najważniejszych zadań dla kształcenia pedagogicznego wydaje się stworzenie systemu profesjonalnej edukacji nauczyciela potrafiącego sprostać przyszłym wyzwaniom. W artykule przedstawiono priorytety i innowacje wprowadzane w tym zakresie na Ukrainie w odniesieniu do polskiego systemu edukacji i europejskich rozwiązań. Zwrócono uwagę na ich znaczenie w myśleniu o polityce edukacyjnej i formowaniu elementów strukturalnych systemu kształcenia oraz wpływ na rozwój wiedzy społeczeństwa.
    The article deals with the problem of professional education of students of pedagogical universities. It is emphasized that an important task of pedagogical science is the development of a system for the modernization of university education. The basis and main stimulus of this process is globalization, a new world trend through which the way of life, the spread of consumer goods and ideas become standardized throughout the world. The main directions of the national priorities Ukrainian innovations and their importance for the Polish education system are presented. The areas of the Ukrainian-Polish cooperation of educational systems in the context of modern innovations and in the sphere of the European priorities are considered. Attention is drawn to the importance of thinking about educational policy and forming structural elements of the education system and the impact on the development of a knowledge society.

    Opis:
    A compressive optical image encryption method, which combines compressive sensing with phase-shifting interferometry on a joint transform correlator, is proposed in the fully optical domain. The object image is first permutated using a binary scrambling method. Next, the permutated object field is encrypted and registered as the holograms by phase-shifting interferometry on the joint transform correlator setup. Then, the encrypted images and the key are compressed to the compressed data using single-pixel compressive imaging. The original image can be reconstructed and decrypted using the specified algorithm. The simulations demonstrate that the method is effective and suitable for image security transmission.

    Opis:
    Micro-flotation and batch flotation tests were carried out on fine (-20 µm) hematite to investigate the influences of non-polar oil when sodium oleate, octyl hydroxamic acid, or oleoyl hydroxamic acid was used as a collector. Both micro-flotation and batch flotation tests were performed using single hematite mineral and/or artificial mixed minerals (hematite:quartz = 1:1), and kerosene was utilized as the neutral oil. The experimental results showed that the addition of a kerosene emulsion benefited hematite recovery in the micro-flotation tests where a froth layer did not exist. In the batch flotation where a froth layer existed, kerosene behaved differently when used in conjunction with the three collectors. Kerosene helped improve the batch flotation when sodium oleate or oleoyl hydroxamic acid was used as a collector. However, it reduced concentrate weight yield, grade and recovery to a noticeable extent when octyl hydroxamic acid was used as a collector, especially at low dosages. In addition, single hematite batch flotation kinetics tests coupled with water recovery measurement were carried out to study the role of kerosene at different collector dosages. It was observed that water drainage and the resulting froth destabilization by kerosene was dominant at low collector dosages, especially in the flotation using octyl hydroxamic acid. At higher collector dosages, the water drainage and froth destabilization effect by kerosene was possibly counter-balanced by the higher hematite surface hydrophobicity and bubble surface tension gradient, which led to more stable froth layer.

    Opis:
    This paper present a new fuzzy iterative learning control design to solve the trajectory tracking problem and performing repetitive tasks for rigid robot manipulators. Several times’ iterations are needed to make the system tracking error converge, especially in the first iteration without experience. In order to solve that problem, fuzzy control and iterative learning control are combined, where fuzzy control is used to tracking trajectory at the first learning period, and the output of fuzzy control is recorded as the initial control inputs of ILC. The new algorithm also adopts gain self-tuning by fuzzy control, in order to improve the convergence rate. Simulations illustrate the effectiveness and convergence of the new algorithm and advantages compared to traditional method.

    Opis:
    The friction and wear properties of 201HT aluminum alloys and the corresponding competitive coupons were tested on an electro-hydraulic servo face friction and wear testing machine (MM-U10G). The microstructures of the competitive coupons were investigated by scanning electron microscopy (SEM) and consequently the corresponding friction and wear mechanisms were studied. The results demonstrated that: (1) the best competitive material of friction and wear performance of the 201HT was the 201HTC. (2) the 201HTC modified by carbon following the initial mill for oil storage of the micro-groove to be produced, increased the corresponding lubrication performance reduced the friction coefficient and wear rate effectively. (3) the 201HT-201HTC could obtain both better friction and wear mainly due to the initial process of grinding following the 201HT plastic deformation occurred in the surface and the formation of a series of re-melting welding points, whereas the 201HT material hardness would be similar to the 201HTC material hardness, which led into the competitive material friction and wear performance improvement.

    Opis:
    The time domain boundary element method was utilized to simulate the propagation of the irregular waves in a numerical wave tank. The problem was solved in a time-marching scheme, upon the irregular waves being fed through the inflow boundary, in which the theoretical solution was obtained from the wave energy spectrum. The open boundary condition was modeled by the multi transmitting formula (MTF), in which the phase velocity was calculated according to the Sommerfeld’s condition. The velocity potential and wave elevation were directly obtained by integrating the free surface condition twice, with respect to time. The accuracy of the developed numerical scheme was verified by simulating the propagation of irregular waves. The numerical results show good agreements with the analytical solutions, which prove that the proposed scheme is a promising way to the simulation of wave-body interactions.

    Opis:
    In order to completely eliminate, or greatly reduce the number of phase wraps in 2D wrapped phase map, Gdeisat and co-workers proposed an algorithm, which uses shifting the spectrum towards the origin. But the spectrum can be shifted only by an integer number, meaning that the phase wraps reduction is often not optimal. In addition, Gdeisat’s method will take much time to make the Fourier transform, inverse Fourier transform, select and shift the spectral components. In view of the above problems, we proposed an improved method for phase wraps elimination or reduction. First, the wrapped phase map is padded with zeros, the carrier frequency of the projected fringe is determined by high resolution, which can be used as the moving distance of the spectrum. And then realize frequency shift in spatial domain. So it not only can enable the spectrum to be shifted by a rational number when the carrier frequency is not an integer number, but also reduce the execution time. Finally, the experimental results demonstrated that the proposed method is feasible.

    Opis:
    This paper reviews two techniques that have been recently published for three-dimensional profilometry and proposes one shot profilometry using iterative two-step temporal phase-unwrapping by combining the composite fringe projection and the iterative two-step temporal phase unwrapping algorithm. In temporal phase unwrapping, many images with different frequency fringe pattern are needed to project, which would take much time. In order to solve this problem, Ochoa proposed a phase unwrapping algorithm based on phase partitions using a composite fringe. However, we found that the fringe order determined through the construction of phase partitions tended to be imprecise. Recently, we proposed an iterative two-step temporal phase unwrapping algorithm, which can achieve high sensitivity and high precision shape measurement. But it needs multiple frames of fringe images which would take much time. In order to take into account both the speed and accuracy of three-dimensional shape measurement, we get a new, and more accurate unwrapping method based on a composite fringe pattern by combining these two techniques. This method not only retains the speed advantage of Ochoa’s algorithm, but also greatly improves its measurement accuracy. Finally, the experimental evaluation is conducted to prove the validity of the proposed method.

    Opis:
    A novel magneto-optical current sensor (MOCS) with two sensing arms is proposed to improve the temperature stability. One of the arms, with a highly stable permanent magnet attached and orthogonal to the other one, is designed to provide a reference that follows the temperature characteristics of the sensing material. By a normalization operation between two arms, the temperature drift is compensated adaptively and a sensing output proportional to the measured current can be reached. A dual-input and dual-output structure is specially designed for the reference sensing arm to demodulate the DC Faraday rotation angle. This scheme compensates simultaneously two main temperature influence factors, the Verdet constant and linear birefringence. Validation tests were carried out and are discussed.

    [Fe/Pt]ₙ multilayer films were prepared on thermally oxidized Si (100) substrates at 300°C using dc magnetron sputtering and annealed for different temperature ranging from 350 to 500°C. It is found that the as-deposited [Fe/Pt]ₙ multilayer films exhibit well-resolved periodic structures and low roughness of interface. The ordering degree of the annealed films decreases and their perpendicular magnetic anisotropy deteriorates with increasing the period number. Fe/Pt bilayer film annealed at 350°C shows (001) orientation and hard magnetic characteristic, the coercivity and perpendicular anisotropy enhance with increase of annealing temperature. In addition, the hard and soft magnetic phases are not fully magnetically coupled in the Fe/Pt film annealed at higher temperature.

    Opis:
    Commercial seed lots of onion (Allium cepa L.) of the cultivars "Octavia" and "Eureka" were soaked for 12 h in water of the temperature 20°C, then they were exposed to low frequency magnetic field (20 mT) for 10, 30, and 60 min. The field was generated using a standard device for magnetic stimulation VIOFOR JPS applied in human medical treatment. Next, the seeds were evaluated for energy and capacity of germination, length of the received germs as well as fresh masses of the obtained seedlings using the routine methods recommended by the International Seed Testing Association. For the seeds of the cultivar "Octavia", the field did not affect the energy of germination, however it did improve in all tested treatments their germination capacity. In the best of them (60 min), the germination capacity increased by 4.6%. For the seeds of the cultivar "Eureka", the tested field increased their energy of germination, which improves evenness of plants emergences in the field and has a significant importance for horticultural practice. When the seeds were exposed to the field for 60 min, their germination energy increased from 40% (control) to 63%. This result was accompanied by no differences in both length of germs and fresh masses of the received from them seedlings.

    Opis:
    Toxoplasma gondii is a parasite that has been extensively studied due to its medical and veterinary importance in terminating pregnancies. Consequently, a satisfactory vaccine is required to control its adverse effects on pregnant animals. The microneme protein, MIC3, is a major adhesion protein that binds to the surface of host cells and parasites, and is therefore a potential vaccine against T. gondii. The viability of MIC3 as a vaccine is investigated in this study. Sheep were injected twice, intramuscularly, with plasmids containing DNA encoding for the mature form of MIC3 protein formulated into liposomes. Control sheep were injected with an empty vector or received no injections. The injection of sheep with DNA plasmids encoding for MIC3 elicited an immune response after the first and second injections as indicated by antibody responses and the production of IFN-γ. The immune response, as measured by the IgG2 and IgG1 serum levels, was boosted after the injection of the MIC3 DNA vaccine together with high anti-MIC3 antibodies. The results demonstrate that the intramuscular injection of sheep with a plasmid containing DNA coding for MIC3 protein induces a significant and effective immune response against T. gondii.

    Opis:
    The evolution of the microstructure of hexanitrohexaazaisowurtzitane (CL-20) after a thermal stimulus plays a key role in the performance of CL-20. In the current work, microstructural variations of CL-20 caused by thermal treatment were investigated by X-ray diffraction, in situ variable-temperature optical microscopy, atom force microscopy, and small-angle X-ray scattering. A wave-like process, an abrupt volume expansion, movement, and fragmentation of CL-20 particles during phase transition were observed. After the phase transition (160 °C) the CL-20 sample acquired a very rough surface with numerous dimple depressions, and during the thermal decomposition stage (200 °C) a large number of voids were produced in both the bulk and the surface of the CL-20.
