The main radio equipment used by aviation specialists are communication, radar and radio navigation systems. Training of students in these areas is a complex task that requires significant efforts of lecturer. The article proposes a concept of simulator designing that are supposed to be adopted in the educational process of civil aviation institutions based on hybrid approach to the virtual simulators designing. Such concept was applied in the development of methodology for designing of simulators for flight electronic support, which involves solving the problem of selective structural synthesis. The problem of selective structural synthesis of design solutions is described using a morphological tree and implies finding the graph edge that ensures meeting a set of rules with the constraints specified in the process of specification drawing up, which is replenished by the developer-user. Due to random nature, the structural optimization method implies a sequential search for possible options. A computer-aided system of simulator designing for flight electronic support systems was developed based on the methodology. The development of a computer-aided system of simulator designing for radio communications, radar and navigation equipment makes it possible to provide effective training of future pilots and air traffic control officers.

The Railway Troops of the Armed Forces of the Russian Federation are intended for technical cover, restoration, demining and barrage of sections (objects) of the RF railroad transport infrastructure in the RF Armed Forces responsibility zone, increasing its survivability and carrying capacity, as well as planning the guidance and operation of floating railway bridges. The railway infrastructure is understood as "a technological complex, which includes subsystems of railway infrastructure, components of subsystems and elements of components of subsystems of railway infrastructure, ensuring the functioning of this complex" [1]. The tasks of the troops include the operation of existing and construction of new sections of railways, bypassing railway (railway) junctions, the construction of temporary railway bridges in order to ensure the actions of troops [2]. When restoring infrastructure facilities for railroad transport, the organization of work management and the promptness of restoring interrupted train traffic play a decisive role, which largely depends on the preparation and decision-making that requires certain engineering calculations. In particular, the development of design documentation for the construction of a bypass of a destroyed section of a road or a railway junction requires a significant amount of time. The most time-consuming document of design documentation is the calculation and construction of a longitudinal bypass profile. The article discusses the issues of automated construction of a longitudinal bypass profile, which can significantly reduce the time required for preparing design documentation, including for laying cable lines to restore the regulation of train traffic.

The article describes the information and analytical systems (IAS), the main function of which is processing of large multidimensional arrays of information under conditions of destructive effects caused by attacker. Such conditions require the management of secure data storage. It ensures the data sent for storage by operator is identical to the one used by a decision-maker upon request. The authors propose the subsystem of data integrity control that uses cryptographic hash functions. The applied hash functions are based on the rules for constructing Pascal’s triangle. The paper shows that a distinguishing feature of the subsystem is reducing the input redundancy of control information at a given security level of data processed in the IAS, as well as ensuring new properties, such as the ability to control the integrity of not only the data to be secured, but also the reference hash codes. The article also gives a comparative assessment of the developed subsystem with known methods of data integrity control.

An electrothermal compact model of SiC MOSFETs for analyzing avalanche failure mechanisms
Authors: Shimozato Kyohei , Nakamura Yohei , Bian Song , Sato Takashi
Published: January 2021

Avalanche failure that occurs in circuits with inductive loads is an important issue facing silicon carbide (SiC) metal–oxide–semiconductor field-effect transistors (MOSFETs). Two mechanisms have been suggested for this failure: the activation of a parasitic bipolar junction transistor (BJT), and the intrinsic operation of SiC at extremely high temperatures. In this study, we propose a SPICE-based electrothermal simulation model of SiC MOSFETs to simulate avalanche behavior. The proposed compact MOSFET model includes a parasitic BJT, a body diode, and an intrinsic resistance. The intrinsic resistor represents the decreasing resistance of SiC due to its intrinsic operation in extremely high temperatures. The simulation results of our model accurately reproduce the measurement results of an unclamped inductive switching (UIS) test. According to the simulation results, the main cause of MOSFET failure in the UIS test is that SiC enters intrinsic operation because of the rapid increase of junction temperature over 1200 K.

The theoretical lateral current of the surface inversion layer in a crystalline silicon (cSi) surface for a p-aSi:H/i-aSi:H/cSi heterojunction (SHJ) solar cell was calculated using computer simulation and was compared with the experimental one to study defects/traps at the aSi:H/cSi interface and/or in the cSi surface and to detect the acceptor concentration (N
a) in p-aSi:H. To experimentally extract the lateral surface inversion layer current, a field-effect transistor type test element group device was co-integrated with SHJ cells on the same wafer. From the correlation between the experimental and calculated lateral surface inversion layer current, the density of defects/traps (D
it) at the aSi:H/cSi interface and/or in the cSi surface and the value of N
a were extracted. The calculated lateral surface inversion layer current stayed unchanged for various minority carrier lifetimes in the substrate, suggesting that this method is not suffered from the variation in the material parameters in the substrate.

Published: January 2021

Analyzing the penetration of cosmetic/medical lotions and creams into the skin is important for evaluating their effectiveness. Hence, the penetration speed of liquids into chicken and pig skins was evaluated using a terahertz (THz) time-of-flight method. An arsenide-free disposable THz emitter comprising a silicon film on a sapphire substrate was developed for practical measurements using skin samples. The skin sample was mounted on the THz emitter surface directly so that the generated THz pulses in the silicon film were easily focused on the skin sample. To evaluate the time evolution of the penetration depth, the arrival times of the reflected THz pulses at the edge of the liquid-penetrated region on the skin were observed. As a preliminary experiment, measurements using a stack of conventional glass slides were conducted. In addition, the penetration speed into the chicken and pig skin was compared to prove the practical applicability of our method.

A hyper-lens with planar object/image surfaces and uniform magnification factor is designed based on directional projecting property of optic-null medium (ONM). The proposed planar hyper-lens only requires one homogeneous anisotropic medium, i.e. ONM. We use metallic plates inside ϵ-near-zero medium to realize the proposed hyper-lens. 0.191λ
0 resolution is observed (0.238λ
0 can be clearly resolved) in experimental measurement, which consists very well with 3D numerical simulations and verifies the performance of the proposed planar hyper-lens. The planar hyper-lens with uniform pre-designed magnification factor may have some applications in super-resolution imaging technology.

Published: January 2021

Interactions of iron atoms with dislocations in n-type Czochralski silicon have been studied by combining deep level transient spectroscopy (DLTS) and electron beam induced current (EBIC). The EBIC results indicate that dislocations facilitate the aggregation of iron atoms. The DLTS reveals three levels K1 (E
c—0.17 eV), K2 (E
c—0.35 eV) and K3 (E
c—0.48 eV). The amplitudes of K2 and K3 peaks exhibit extended localized states. The origin of levels K2 and K3 is attributed to iron clusters around dislocations, and the existence of iron clusters in the vicinity of dislocations is further proved.

Published: January 2021

The circular dichroism (CD) performance of conjugated gammadion structure on the end facet of silicon waveguide in the mid-infrared regime is investigated theoretically. By engineering the orientation of the structure, the sign and value of its CD spectrum can be changed. For a fixed gammadion structure, different CD values can be obtained not only by changing the excitation wavelength but the excitation waveguide mode. This finding potentially provides an extra degree of freedom to design integrated chiral photonics chips.

Published: January 2021

We propose an optical tweezer with tunable potential wells, by dynamically manipulating the phase gradient of light. Using our proposed method to design holograms, we can obtain desirable phase profiles and intensity distributions of optical traps. Optical force arising from phase gradient creates tunable potential wells for versatile optical nanomanipulation, such as trapping nanoparticles in peanut-shaped optical spots, positioning and shifting nanoparticles in optical gears, and controllable transport, as demonstrated in our experiments. The tunable optical tweezer has several merits including flexible design, easy control and high tunability, which provides a new tool for exploring novel functions in optical nanomanipulation.

In the past, only mobiles and computers were connected to the internet but in the new era with the advent of new technologies other things like security cameras, microwaves, cars and industrial equipment's are now connected to internet. Internet of things (IoT), there are over several billion electronic equipment de- vices already on the internet, and within a decade these number is expected to scale above 20 billion devices. Smartphones and computers have various software security solutions to defend and protect them from most of threats and attacks, although there are indiscernible security solutions to take care of the rest of the IoT [1]. Lately, as a strong example, several thousands of security cameras were breached to proceed DOS and DDOS attacks that caused the Twitter down. Solutions in the IoT are not exclusively software but the entire physical environment of hardware, World Wide Web (WWW), Software, Cloud and mobile interfaces involved. The IoT ecosystem services are young and not very fully developed yet for these reasons there are main primarily concerns fact around IoT adoption due to security threats/attacks. IoT Top Security Concerns: Secure constrained devices, Secure communication, Keeping IoT hardware updated, Distributed Denial of Service (DDoS), Authorize and authenticate devices, Ensure data privacy and integrity. This research reviews the achievements of mitigation IoT security challenges and the key viewpoint is for authors to clearly dene adversary goals, assumptions and dependencies.

Analysis of structural construction of existing three-dimensional accelerometers is carried out, in which due to the opposite direction of sensitivity vectors and direction of measured inertial force, they allow to measure only linear inertia and accelerations varying in relatively small limits. On the other hand, due to the presence of elements in them that create electromagnetic fields, their construction is somewhat complicated. In addition, in known accel-erometers, due to the absence of a measurement object position sensor and an electronic control circuit, the func-tionality of the accelerometer is limited, Due to lack of integrator for acceleration integration, speed measurement is not provided, Due to rigid attachment of piezoelectric sensing elements through their bases, during measurement they generate interference signals, The amplitude of which exceeds the amplitude of the useful signal, which does not ensure reliability of the measured acceleration or speed and due to the presence of sensitive piezoelectric ele-ments, Having higher rigidity and requiring relatively large mechanical forces for generation of signals during mo-tion of acceleration and speed measurement object in automatic mode, which reduces sensitivity of accelerometer. Invention proposes new design and control scheme of three-dimensional piezoelectric accelerometer for measure-ment of dynamic parameters of moving objects in automatic mode. Wherein providing the position sensor of the moving measurement object with a three-axis signal detection unit to determine a direction of motion with meas-urement of acceleration or linear velocity when the measurement object moves along the coordinate axis; With the help of differential operational amplifiers through pulse generators and integrators, Speed measurement is provided by damping piezoelectric elements when the measurement object moves along one of the coordinate axes; Across the other two axes, the generated interference signals by amplitude are significantly reduced by their redemption; Having a piezoelectric element in the structure in the form of two-layer flat plates with an excitation section and a sensor section; Which generates signals at fast-changing acceleration and speed of moving object, amplitude of signal and sensitivity increases in 4-5 due to generation of signal by sensitive elements in vibration excitation mode created in accelerometer. Mathematical basis for accelerometer control circuits, mathematical model of its functioning is developed, applica-tion of which increases sensitivity of measurement of linear accelerations and speeds of moving objects and expands functional capabilities.
