Mutual Exclusion Algorithm for Real-time Traffic Dispatching Based on Game Theory
Authors: Jiang Jianchun , Peng Fei , Zhao Bowen 
Published: April 2020

Abstract
With the rapid increase of vehicles, real-time dynamic dispatch is an important means to alleviate traffic congestion. Game theory-based real-time vehicle scheduling algorithms are often used for dynamic adjustments, but traditional algorithms only switch signal phases for fixed phases during dynamic adjustment scheduling, and cannot achieve the comprehensiveness of real-time scheduling; or phases with large differences in traffic flow when setting the duration, the reasonable waiting time for the smaller traffic phase are not considered. In order to solve the real-time dynamic adjustment of signal lights, an improved algorithm based on game theory is designed to control the signal switch in the game mode, and the waiting time of vehicles at traffic intersections can be reduced by adding parameter values of lane waiting time changes. Through experimental comparison, the algorithm reduces the vehicle stay by 3.4% and the waiting time by 4.4% compared with the fuzzy algorithm of the polling mechanism.

Published: April 2020

Abstract
In view of the false data injection attack of cyber physical systems (CPS), this paper aims to study the designing method of adaptive compensation controller for system executor when the system executor suffers from constant false data injection attack. The application of the adaptive compensation control algorithm to the false data injection attack shows that the designed adaptive law has the advantages of fast convergence speed and accurate parameter estimation. The compensation control algorithm can substantially compensate for the effects of false data injection attacks, and we can prove that all signals of the final closed-loop system are bounded and the state of the system can asymptotically converge to zero. Finally, we provide simulation examples to verify the effectiveness of the state feedback adaptive compensation controller proposed in this paper.

Authors: Wang Ruizhi , Dong Lei 
Published: April 2020

Abstract
By considering the uncertainty of renewable energy in AC/DC active distribution network with power electronic transformer (PET), this paper proposes a linear robust optimized dispatch method with PET contained. Firstly, a steady-state model that only takes into account the characteristics of PET port is established. Secondly, we linearize the power flow equations of the AC/DC distribution network, and derive the expressions for the voltage safety at network nodes and for the current safety of lines, then establish the robust optimized dispatch model of the AC/DC distribution network containing PET. Finally, the nonlinear constraints such as port capacity in the network are linearized, and the robust optimized dispatch model is transformed into a quadratic programming model without uncertain variables using dual optimization theory, so that the model can be solved in an efficient and fast way. The two modified IEEE33 node systems have constructed the AC/DC active distribution network with PET. The simulation verified the accuracy and effectiveness of the proposed method.

Simulation Study on the Impact of Uneven Fuel Injection of Each Hole of the Diesel Engine Injector on the Combustion Process
Authors: Zhou Liying , Liang Yu , Xu Mingfei 
Published: April 2020

Abstract
The spray impulse and injection pressure of each hole of the 4-hole injector of F186 engine were tested by using the transient test system for flow coefficient and injection rate of each hole of the injector, and the injection rate, fuel injection quantity and flow coefficient of each hole were obtained. According to the measured injection rate of each hole and cycle fuel injection quantity, a 3D model of the diesel engine was established with the FIRE software, and the uniform injection rate and uneven injection rate of each hole were made as the injection setting for the combustion simulation to comparatively analyze the influence of the uneven injection rate of each hole on the combustion process of diesel engine. As the injection of each hole is uneven, some holes with high injection rate have long fuel spray penetration distance and the fuel spray is fully mixed with the air, and the ignition starting point is moved ahead. When compared with the case of uniform injection rate, the phase corresponding to the heat release rate in the case of uneven injection rate is moved forwards, the maximum cylinder pressure and temperature rise fast, the maximum cylinder pressure and maximum average temperature in cylinder are higher, the NO generation is larger, and the Soot generation is slightly larger. In the case of uneven injection rate from four holes, as the utilization of air in the hole-located cylinder space by the fuel spray is uneven, the hole with a large quantity of injection makes the oxygen in the hole-located cylinder space relatively low, the wall collision of the hole with high injection rate is more, and the diffusion combustion is incomplete and insufficient.

Published: April 2020

Abstract
With the rapid development of the aircraft industry, more regulations on aircraft noise are established. The turbulent jet is one of the major sources of noise in the aircraft, extensive researches on noise reduction has been investigated, especially for chevron. In this project, the near-nozzle flow fields of three chevron nozzles and one circular nozzle from a subsonic jet are investigated experimentally. This paper presents the results the comparison between four nozzles (CN0, CN1, CN2 and CN3) in terms of radial mean velocity, turbulent intensity and the selected nozzles are compared to baseline and each other with respect to turbulent kinetic energy spectra. CN0 is the baseline circular nozzles, CN1 is the standard chevrons nozzle, CN2 is a chevron with alternating angles and CN3 is chevron with more number of chevrons. Fluctuated velocity profiles were measured at x/D = 2 at different radial locations along characteristic direction using hot-wire technique. The purpose of these measurements and comparison is to study the variations in the flow field with the different configurations of chevron, which might be related to the acoustic field. CN1 nozzle has a 40dB turbulent kinetic energy reduction compared to the baseline nozzle CN0, and CN2 has the highest turbulent flow field, which is a mixture of low, medium and high velocities corresponds to three directions. CN3 has the most similar mean velocity and turbulence intensity profiles, this may be caused by the under developing jet flow field.
