A novel dual mode logic (DML) model has a superior energy-performance compare to CMOS logic. The DML model has unique feature that allows switching between both modes of operation as per the real-time system requirements. The DML functions in two dissimilar modes (static and dynamic) of operation with its specific features, to selectively obtain either low-energy or high-performance. The sub-threshold region DML achieves minimum-energy. However, sub-threshold region consequence in performance is enormous. In this paper, the working of DML model in the moderate inversion region has been explored. The near-threshold region holds much of the energy saving of subthreshold designs, along with improved performance. Furthermore, robustness to supply voltage and sensitivity to the process temperature variations are presented. Monte carol analysis shows that the projected near-threshold region has minimum energy along with the moderate performance.

W referacie zostaną przedstawione metody pomiarów, wyniki z pomiarów oraz sposoby zabezpieczeń przed ewentualną ekspozycją pasażera na te pola. Otrzymane wyniki z pomiarów porównywane są dopuszczalnymi poziomami przy jednoczesnym wnioskowaniu, czy dany pojazd spełnia wymagania zawarte w odpowiednich normach oraz przepisach krajowych i czy może zostać dopuszczony do ruchu aglomeracyjnego na terenie kolejowym. Omówione zostaną pomiary pól promieniowanych bezpośrednio oraz zaburzeń elektromagnetycznych przewodzonych w pokładowej sieci zasilania niskiego napięcia.

The paper presents measurement methods,measurement results and methods protecting a passenger against exposure to electromagnetic field. The results of the measurements are compared with acceptable levels of electromagnetic radiation and at the same time it is analyzed if a given vehicle complies with the applicable norms and regulations and if it may be allowed to circulate in the railway traffic. The herewith article analyzes the measurement results of directly radiated fields and electromagnetic interferance conducted in the onboard low-voltage power system.

The paper describes the results of quadrocopters motion properties for the control based on the inverse dynamics method and optimal control method with synthesis linear-quadratic regulator (LQR). Motion of quadrocopters is tested for composite trajectories. The new model of asymmetrical quadrocopters, taking into account the rotation and shift of one arm relative to the other, was developed. A few criteria for evaluation of the effectiveness of control methods of quadrocopters are presented in this paper. An analysis of the results allows selecting a method for solving the problem of quadrocopters control and making recommendations for the formation of trajectories.

Abstract In this work, the mass throughput rate in a radiation processing center, equipped with an X-ray facility, is calculated by means of a curve against the thickness of the material, along with the variation of dose uniformity. Therefore, depending on the desired dose value, the best thickness and the mass throughput rate can be calculated. The calculation results for the 5 and 10 MeV X-ray bremsstrahlung for polyethylene and wood as the irradiation products, have been obtained by using a Monte-Carlo computer code. In addition, the experimental results at the same geometry and materials were compared with those calculated.
