We describe a procedure of compact behavioral models design of the communication channel through a borehole pipe for measurement while drilling (MWD) microwave systems based on results of measurements of radio pulse signals during testing of the channel. Characterization of the microwave channel for the decline-directed borehole and a transmitter on the Gunn diode is described as an example of the offered process. The procedure is based on measurement of signal samples of the transmitter with the subsequent accounting of electrodynamical parameters, attenuation in the media, and on the pipe walls.

This article presents the imitation computer model of a synchronous-in-phase electric drive that takes into account the impulse type of the control system, which allows simulating transient processes with high accuracy while studying effective methods of synchronous-in-phase electric drive control and devices implementing these methods. The modelling accuracy when using the developed model is especially increased (in comparison with the model that doesn’t consider the impulse type of the control system) when studying transient processes in the low-frequency range of the electric drive rotation. The developed model allows to carry out researches of the electric drive in a range of low frequencies, where there is a strong influence of signal discretization on the transient processes type.

Anonymous Voice over IP (VoIP) communication is an important tool to provide freedom of speech. For achieving a good trade-off between quality of service (QoS) and anonymity, connecting mixes by padded links is a promising approach. However, constructing suitable overlay topologies for establishing padded links is not easy: existing approaches are either not scalable with regard to the number of mixes because of using full meshes or impractical due to computational complexity of the algorithms used to create optimal reduced topologies. This prevents them from being deployed as volunteer-based networks like Tor. In this paper, we propose and study different heuristic strategies for reduced topology construction and path selection with low computational complexity. We evaluate our approach using latency and bandwidth estimations from the Tor network and demonstrate that we can achieve appropriate performance and anonymity metrics for VoIP. Especially, the achieved properties are similar to those of a recently proposed approach that calculates optimal topologies for small networks.

One considers the measurement of the rotationrate of the asynchronous submersible electrical motors (SEM) by placing on its shaft on dielectric beams located at the two end sides of k non-magnetic intermediate bearings of the rotor of 4k four-pole magnets with radially magnetized zones of different polarities, oriented strictly to the same direction. Measuring information is generated directly by SEM stator winding and is transmitted to the surface via a power cable and is removed through the current transformer and a bandpass filter from the cable line phase. The results of circuit simulation are presented in software package confirming the validity of the measuring data.

We considered the issues of synthesis of the algorithms for adaptive nonlinear signal processing using feed-forward blocks of nonlinear transformation under the influence of non-Gaussian noise with unknown density of distribution of instantaneous values or its envelope. It is shown that to plot the adaptive feed-forward blocks of nonlinear transformation, the algorithms for estimating the parameters of linear model of probability density function of noise can be used. This model is presented in the form of a generalized polynomial of decomposition in a series of linearly independent functions, and, also, in the form of nonlinear models, such as generalized Gaussian distribution and abnormally cluttered distribution.

This paper aims at presenting the approach for the process of attributes verification in the Attribute-Based Encryption schemes. We considered ABE methods in the Internet of Things environment. The main idea is to allow users or device owners to verify attributes using standardized and well-known authorization protocols like Oauth2. More accurately, Attribute Authority will use Authentication as a Service approach for users and device controllers authentication. We described software service for Attribute-Based Encryption methods in the context of FIWARE platform. Components of this platform use Oauth2 for authentication and authorization mechanisms. More specifically, we developed a web application which allows devices to create orders for ABE secret keys with particular attributes. Further users should approve or deny these orders. We used FIWARE components for users and devices authentication. To the best of our knowledge, it is the first implementation of ABE algorithms in FIWARE ecosystem.

The paper describes development of accommodation systems for faults caused by change of coefficient of coulomb friction value in electric servo actuators of manipulation robots. The proposed method develops diagnostic observers for detection and isolation of faults using logic-dynamic approach. A feature of this approach is the possibility of diagnosing systems even with nonsmooth nonlinearities using linear methods. For solving the task of fault values estimation, a feedback by residual signal was proposed to use in observers. The efficiency and operability of the proposed fault accommodation system was confirmed by mathematical modeling.

In this paper we consider two ways of the jumping robot can execute acceleration that differ from each other in terms of the sequence of stages. The robot consists of the body and the acceleration module. In the first case the acceleration module is first positioned as required relative to the surface and then the robot accelerates. In the second case positioning and acceleration occur simultaneously. A mathematical model of robot motion during acceleration is developed, as well as a model of contact interaction with the surface, a classification of acceleration modes is proposed and conditions under which they are observed are formulated.As a result of the numerical simulation, two acceleration modes are established under varying control and geometric parameters of the robot, as well as the properties of the supporting surface. During both modes the robot makes contact with the surface at two supporting points, but in one mode these points are fixed, while in the other they glide over the surface. The diagrams of the acceleration modes are constructed.

The article discusses the issue of creating the principle of induction motor providing a symmetrical three-phase voltage supplied from the single-phase electrical network. The analysis of the operation of the circuit is shown for providing a symmetrical three-phase voltage system of induction motor stator windings with the mechanical load on its shaft. As a result of the analysis, the laws of changing the current values of single-phase sources and asynchronous motor phases, changing the power consumption of active and reactive sources, as well as the change in the power factor of the first, second source and asynchronous motor depending on the slip are determined. Thus, the circuit discussed in the article can be used to create a symmetrical three-phase voltage.
