2018 Moscow Workshop on Electronic and Networking Technologies (MWENT). Proceedings
MWENT-2018, the first Moscow Workshop on Electronic and Networking Technologies that is just started but is supposed to be a premium international conference fully sponsored by the IEEE Russia Central Section and Electron Devices Society of the IEEE. The uniqueness of MWENT among first-class international conferences is that it is held in rapidlygrowing place providing opportunities for exchanging information and ideas in electronic and networking field. The MWENT Workshop Technical Program Committee has established the level of the event to connect scientists with professionals, encourage students and young professionals to do research and support the transfer of research results into industry and supporting activities. They want to keep an appropriate environment for development of national Electron industry and society in general. The papers, sessions and keynote presentations have been selected to highlight both the longestablished fields in electronic and networking technologies and the newer areas as optoelectronics where micro- and nanoelectronics will contribute substantially to the well-being of mankind.
Because the conference is limited to three days, it was necessary to reject almost twice as many papers contributed. The final selection was made by the program committee team at online meetings, who worked diligently to evaluate over 350 papers. Proceedings contains the full-length papers of all invited and regular papers followed by all the MWENT contributed papers grouped by Sessions. The selected papers are organized in four parallel tracks of Sessions made of 5 to 7 papers grouped around topics of MWENT namely: wireless communication circuits and systems, control systems, RF circuits, networks, data converters, sensors, and micro- and nanosystems.
The importance of circular systems within radio-schemes increases in the process of transition from marco-to mirco- and then to nano-levels. It is worth mentioning, that on the macro-level any electric chain (since the time of Kirchhoff) as well as the simple radio circuit is usually replaced for necessary calculations by the model system of the interfaced closed chains, cycles (circles) and is being afterwards calculated, investigated or being really assembled, each cycle separately. Theoretically each fixed “coloured” point of a circle can define the function of any circle's element (the resistor, the condenser, the source, the rectifier, the transistor, etc.) or it can correspond to the material (conductor, insulator and so forth). The analysis and the computer modelling of the circles and their nano-structural elements are the purpose of this work.
The article describes a model of a parallel matrix switching system based on colored Petri Nets (CPN). The CPN-based model developed by us describes the parallel switching algorithm. The CPN-based model is a hierarchical network containing inhibitory arcs. Due to the use of timed CPN, we obtained the dependence of the average queue length on the intensity of the flow.
Welcome to MWENT-2018, the first Moscow Workshop on Electronic and Networking Technologies that is just started but is supposed to be a premium international conference fully sponsored by the IEEE Russia Central Section and Electron Devices Society of the IEEE. The uniqueness of MWENT among first-class international conferences is that it is held in rapidlygrowing place providing opportunities for exchanging information and ideas in electronic and networking field.
Logging-while-drilling (LWD) telemetry systems have been designed relying on cable-based equipment or advanced signal processing techniques applied to the electromagnetic channel through ground. The main disadvantage of such systems consist in the fact that measurements can be actually carried out only when the drilling operation is stopped. In this paper, a dedicated X-band equipment for LWD telemetry along pipes regarded as dielectric waveguides is proposed. A hybrid-integrated power amplifier-transmitter for this purpose is described. This system represents a modern solution to geophysical applications where transitions from vertical to horizontal drilling are required. Drilling pipes provide a new communication channel for telemetry although the potential issues related to large attenuation in the soil and external disturbances are to be carefully assessed beforehand. In particular, great attention has to be put in such a way as to achieve an efficient excitation and reduced distortion of the radio signal propagating along the pipe. In the paper we put in details the simulated performances, transmitter design, and current-efficiently issues. The output power is up to 10–25 Wt in short-pulse mode, at central lobe of 9–10 GHz. This level of power is sufficient for the short boreholes. The proposed amplifier-transmitter is used to establish a new communication channel. It is link between surface and the drilling point. Some review explaining the great degree of interest in this topic is presented. Experimental measurement results are provided as well.
Statistical modeling methods, in particular, the factor and multiple regression analysis are offered to use for the variable attenuator design. It is shown that the statistical methods which are earlier not used for decision of the given problem, allow to reveal physical laws of elements operation in device. It promotes creation of structure with minimum phase shift at regulation of transfer factor or insertion loss. At the controlled attenuator design it is necessary to reveal the factor loadings separately influencing to phase variation and insertion loss. Revealing and interpretation of the factor loadings influencing to investigated characteristics, allows to change the traditional methodology and essential simplify optimization of the phase compensating and adjusting parameters of attenuator. The software system Statistica is used for modeling.
