The issues of energy efficiency of decentralized power complexes with superconducting equipment through the use of protected intellectual dialogue automatic control system that performs the adaptation to the complex modes of operation, external perturbations and conducting biometric access control of operators are considered.
In the paper is considered the task of control the process of information interaction in heterogeneous virtual network of cyber-objects. We propose the infrastructure model that allows using various technologies of OSI transport layer, including multi-protocol wireless data exchange tools. The simulation results of access to telematics services confirm the possibility of creating sustainable delay-tolerant virtual channels.
An increase in the number of cars is higher than rates of transport infrastructure development, resulting in a reduction of cargo and passenger transportation efficiency in city conditions. Simulation of flow irregularity in time (peak hour) shows the key role of a car motion interval as a factor of overcoming accumulation at average speed reduction in conditions of highly loaded roads. To reduce the effective time of driver reaction, defining the least distance between cars, it is necessary to minimize the influence of human factors. Automation of the process (unmanned control) requires an effective exchange of navigation and route data between traffic participants. A summary of requirements for such an information exchange system defines the priority of the suggested communication and navigation system (CNS) on the base of radio broadcast communication. Its application gives an opportunity to rise simultaneously traffic safety and efficiency. An increase in neighbor driver action predictability leads to traffic safety ensuring. The exchange of data with traffic control centers (TCC) enables the centralization of motion regulation. A distributed network of transceiver stations forms a local positioning system based on trilateration principles. Algorithms of onboard positioning result verification and automatic resolution of communication conflicts ensure high reliability of CNS functioning. Refusal from point-to-point communication principles allows it to operate even in conditions of high car density up to several thousand per square kilometer. In cooperation with advanced technologies of traffic organization (formation of city highway grid and “total green wave” mode), CNS and TCC are capable of rising the average speed in city conditions higher than 45 km/hour. The aggregate economy of expense on last mile transportation because of the suggested innovations is to be at the level of several GDP percent due to a decrease in accidents and congestion even without accounting for social and ecological effects.
Modern hardware systems of processing the video data stream for color coding apply the principle of constant brightness proposed in the development of the NTSC color coding system. This principle, like its implementation, is not free from drawbacks: loss of information on the clarity of the encoded color images, degradation of clarity in achromatic details and images as the color saturation increases, etc. In addition, the use of video data decoding formats in digital video data processing systems, such As 4:2:2, 4:2:0, 4:1:1, distorts the decoded video image.
An alternative approach for encoding a color video stream is to apply the principle of constant color luminance. The work describes the coding according to the principle of constant color luminance. A comparative analysis of the transformed images is carried out with the help of the two principles given. The advantage of applying the principle of constant color brightness in digital video coding systems is shown. It is shown that using the principle of constant color brightness it is possible to obtain a gain of more than 6 dB.
The implementation of the principle of constant color luminance for real and integer modern hardware platforms is described. A comparative analysis of the realizations of the principles of constant brightness and constant color luminance was carried out, showing the advantage of applying the principle of constant color luminance for some modern processors.
The application of the principle of constant color luminance in digital video encoding systems can help improve the quality of recoverable color coded images.
The transformable designs of space basing are delivered into orbit in a folded state, which creates the task of their reliable disclosure. In this paper we propose to use an actuator in the form of electrical machines as the executive body. The use of this type of actuator allows controlling the process of deployment.
As a large-sized transformable structure we consider the space-based reflector. At present, the transfer of the machines from the folded state to the operation state is carried out by stages. The paper considers the joint implementation of two stages: the rotation of the root unit of the spoke and the extension of the intermediate unit. Mathematical models for rotational and translational motions are developed which take into account such parameters as bending and contraction of the spoke. Modeling and analysis of the results of different variants of the joint disclosure of the reflector elements are made: the use of the engine for each of the components of the motion and the use of centrifugal force for the extension of the spoke.
The application of the algorithm for correcting the control parameters is considered. One of the important advantages of the algorithm is the ability to carry control in real time. It can be used to calculate the reference control in algorithms based on the two-channel principle.
