Published: April 2020

Indonesia is located in high seismic zones. Therefore, earthquake dissipated devices such as elastomeric base isolator is needed to minimize building’s damages when an earthquake occurs. In this study, a numerical two-stage analysis was carried out to evaluate the behaviour of elastomeric base isolators. First, elastomeric base isolators were modelled in the finite element software to obtain vertical and horizontal stiffness and damping values based on local rubber of mechanical properties that is obtained from the previous tests. Second, the values of vertical and horizontal stiffness and damping values were analysed in a case study of a ten-stories hospital building located in Padang, West Sumatra, Indonesia using nonlinear time history analysis of seven different ground motion values. The studied results showed that the structure with base isolators using a local rubber base material can reduce damage caused by the earthquake with an indication of an increase in time period, decreased base shear, and also a decrease in displacement of the structure. Therefore, the use of local rubber for elastomeric base isolators is promising a good future for the advancement of the construction industry in Indonesia.

Published: April 2020

The use of GFRP reinforcing bars as an innovative material for substituting steel bars in reinforced concrete is now increasingly popular for structures which are located in corrosive areas. The GFRP bars have low modulus of elasticity (35-51 GPa), such that the stiffness of GFRP reinforced concrete will be lower than those of the corresponding steel reinforced concrete. Lower in stiffness means larger deflection will occur. This paper aims to introduce the use of GFRP bars in reinforced concrete beams particularly in terms of theoretical deflection calculation of GFRP reinforced concrete beams with ratios of 0.5%; 0.8%; 1.1%, and 1.7%; and based on the equations proposed by several researchers and the design guidelines from several countries such as ACI 440.1R-15; CSA S806-12; CNR-DT 203/2006; ECP 208-2005; Fib bulletin 40 (2007).

Authors: Yu Bakeev I , Kazakov A V , Medovnik A V , Oks E M
Published: April 2020

The paper describes the investigations of the influence of a redistributing electrode on the formation of emission plasma near the electron extraction region in a pulsed forevacuum-pressure plasma-cathode electron source utilizing a cathodic arc for generation of emission plasma. The authors show that the use of the redistributing electrode with optimal geometry in the discharge gap of the source provides a fairly uniform emission plasma density distribution. For the used discharge gap and pulse duration up to 5 ms, the use of the spherical stainless-steel redistributing electrode with radius of 6 mm provides rather uniform plasma density distribution near electron extraction region in the investigated gas pressure range 3–15 Pa. A model simulating the formation of plasma in the forevacuum pressure range has been developed. The model considers the scattering of ions of the arc plasma by gas atoms and the formation of gas ions by ionization of the operating gas by high-energy electrons. The calculated distributions of emission plasma density are consistent with the experimental data for different sizes of the redistributing electrode and for different gas pressures. The model and experiment show that the plasma density near the anode mesh increases with increasing gas pressure, for example, increase in gas pressure from 5 to 10 Pa leads to an 80% increase in density of emission plasma.

Published: April 2020

In this paper the authors presented a method of detecting small drone using a background radar under conditions of fluctuations of an effective background scattering surface described by the normal probability density of instantaneous values radar cross section. The paper considered the detection of a moving drone between the radar and the background. The drone moves towards the background. The detection threshold is determined by the Neumann-Pearson test. It is shown that the detector based on consistent filters provides detection of small drones under conditions of multiplicative interference at small fluctuations of the effective surface of background scattering.

Published: April 2020

The paper presents electron beam sintering of functionally gradient (FGM) Al2O3/ZrO2 materials. An electron beam generated by a pre-vacuum plasma electron source for sintering was used. FGM were manufactured with different number of layers of aluminum oxide and zirconium dioxide powders. The layers differed in the percentage of components by volume. It is shown that the sintering of the composite sample occurs during electron-beam heating. After sintering for 10 min at 1600°C, the sample density increases up to 4 g/cm3. The presented photos of cross-sections of the samples indicate low pore content after sintering.

Published: April 2020

The paper considers the reserved structure implemented by using modal filtering. Such reservation is called modal reservation (MR) for short. To ensure certainty, we took a printed circuit boards (PCB) layout with a single MR. Using quasistatic analysis, the maximum voltages at the far end of the transmission line under study were calculated under the excitation of an ultrashort pulse at the near end and the frequency characteristics were analyzed in case of failure of electronic components. The faults of two types were considered: a short circuit and an open circuit. It is shown that the amplitude of the output voltage increases by 38% so the attenuation of the ultrashort pulse decreases from 2.3 to 1.7 times. It is also shown that the bandwidth of the useful signal changes.

The modern development of a general-purpose lamp is focused on using LED-emitting elements in its structure. Despite the fact that the general-purpose lamp development is a well-studied field of lighting engineering, there is a problem to improve the removal and dissipation efficiency of the generated heat into the environment with the beginning of LED emitting structures use in such a lamp. The computer simulation results of the emitting structures of a general-purpose LED lamp containing various materials that contribute to heat removal in a LED linear design are considered in the article.
Investigation of using quadcopter as a means of acoustic and optic surveillance
Authors: Ignatenko N V , Polikanin A N
Published: April 2020

The main problem in performing optic and acoustic surveillance is the distance. Using quadcopters for gaining access to optic and acoustic information allows coming closer to the places of storing, processing and transmitting of information, suggesting that the interception of this information might be unauthorized. The object of surveillance can be located in the places traditionally inaccessible for normal surveillance – on (restricted areas) closed grounds or on a high floor. The objective of this article is theoretical and practical investigation of using civil unmanned aircrafts to perform surveillance. The basic task of acoustic surveillance is to determine the possibility of receiving and recording the signal of appropriate quality in spite of the noises of the quadcopter itself on the basis of the methods of calculation of discrete word intelligibility index developed by N. B. Pokrovsky. The basic task of optic surveillance is to determine the distance of text recognition on the monitor display or paper using traditional cameras installed on quadcopters. The special task is to choose the parameters of a quadcopter, which can be used for the objectives, to determine its possible characteristics of noise, weight, energy and size. In conclusion, the authors determined critical conditions of quadcopter use in acoustic and optic surveillance for understanding the range of necessary preventive measures against technical leak of information.
