Authors: Anshari Muhammad 
Published: April 2020

Abstract
The most challenging issue in Industry 4.0 is the reduction of the human workforce. This study proposes a mastery concept in identifying a job that can be replaced in Industry 4.0 by machine and a job that hardly replaced by machine. It explains in a job matrix format distinguishing types of jobs that need machine or technologies for optimization and jobs that require compassionately for maintaining an identity as a human being. The matrix defines the nature of a job into a routine human to human interaction, complex human to human interaction, human to machine interaction, and finally machine to machine interaction. The job matrix can become a tool for an organization to develop strategies in the Industry 4.0. The research was based on a qualitative method where secondary data gathered from the literature review analysis. The routine job and non-compassion task required will be replaced by machines and technologies. While, job nature with complexity in decision-making, creativity, innovation, and compassion will remain sustainable in the Industry 4.0.
Formation of emission plasma in a pulsed forevacuum-pressure plasma-cathode electron source based on a cathodic arc with redistributing electrode
Authors: Yu Bakeev I , Kazakov A V , Medovnik A V , Oks E M 
Published: April 2020

Abstract
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

Abstract
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.

Authors: Medvedev A V , Gazizov T R , Zhechev Y S 
Published: April 2020

Abstract
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.

Authors: Ignatenko N V , Polikanin A N 
Published: April 2020

Abstract
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.
