Data Collection Optimization Method for Wireless Sensor Networks Based on Linear Regression
Authors: Zhang Meng , Zhang Xiaomei , Huang Yinghui 
Published: August 2019

Abstract
In the event monitoring applications of wireless sensor networks, the sensing data collected by sensor nodes near the same monitoring area has a great spatial-temporal correlation. In order to reduce the amount of data transmission in the network and the energy consumption of communication among nodes, an energy-efficient distributed data collection optimization strategy based on linear regression for wireless sensor networks is proposed. linear regression model of local sensing data is constructed to represent and predict the actual sensing data monitoring values of sensor nodes. Within the allowable range of errors, the node does not need to transmit the actual monitoring sensing data to the sink node, but only transmits the parameter information of the regression model basis function. Without losing the basic structural characteristics of data, the communication overhead caused by frequent data transmission between sensor nodes is effectively reduced, and the linear regression model of sensing data adopts the incremental update method with low computational complexity. he simulation results show that the data collection optimization strategy based on linear regression can effectively predict and estimate perceptual data with less network energy consumption, and achieve the goal of reducing network energy consumption.

Published: August 2019

Abstract
The system based on microservice architecture is a trend of software system development in the future. As there are many independent micro services in the system based on micro services, the reliability evaluation of these micro services and the impact of their reliability on the system reliability have become a problem worth studying. Based on the reliability evaluation of the system based on the service dependency graph and the fault tree, this paper proposes a scheme of automatically generating the service dependency graph with the help of the service registry, and improving the reliability model of service fault tree. When establishing the fault tree, the influence of the system’s fault-tolerant mechanism and different probability of execution path on the system reliability is taken into account, thus improving the accuracy of the model analysis system fault rate.

Published: August 2019

Abstract
The traction transformer is regarded as the core power equipment in the traction power supply system of railway freight-dedicated line. As the time goes on, lots of traction transformers are under the long-term service status in the domestic electrified railway. Nevertheless, based on the present time-based preventive test code for electric power equipment, it is difficult to conduct the decision-makings on theirs running status. Therefore, it is necessary to study and implement condition monitoring and diagnosis (CMD) technologies. In this paper, some typical characteristics of aging conditions are described, such as tensile strength (TS), polymerization degree (DP), CO/CO2 content, furfural concentration, water content. Some analysis methods with development prospect are analyzed based on dielectric response theories, such as recovery voltage (RV) method, polarization-depolarization current (PDC) method and frequency domain spectrum (FDS) method of the oil-immersed insulation traction transformer. However, the insulation aging of traction transformer is a complex kinetic process of chemical reaction, and it is definitely necessary to combine all the effective methods together and synthetically analyze the experimental data and parameters for obtaining a comprehensive conclusion.

Published: August 2019

Abstract
In order to study the influence of different fault conditions on the initial traveling wave amplitude, initial traveling wave arrival time and duration of fault line transient voltage, a fault electromagnetic transient analysis method based on MATLAB/Simulink modeling is proposed. This method uses MATLAB software to build a 10kV railway automatic blocking and continuous power transmission lines system simulation model with a total length of 60km. The system model includes three parts: power system module, transmission line module, data acquisition and processing module. Taking the single-phase ground fault as an example, the sampling frequency is set to 2MHz, and the simulation analysis of different initial phase angles, different transition resistances, different fault distances and different branches before fault points are performed. The single phase voltage traveling wave diagrams in different fault conditions are analyzed, which shows that the analysis method has certain feasibility.

Taking a quasi-rectangular Tunnel in a city as a prototype, a 1:3 scale tunnel test platform is built. Through the analysis of the smoke spread phenomenon and the change of tunnel longitudinal smoke temperature, the smoke exhaust effect of the quasi-rectangular tunnel with longitudinal ventilation in the ignition tunnel and positive pressure ventilation in the non-ignition tunnel is explored. The test results show that under the smoke exhaust mode of the longitudinal ventilation of the ignition tunnel and positive pressure ventilation in the non-ignition tunnel, in the case of a double-hole in an evacuation passage of quasi-rectangular tunnel, when the fire source is located at the evacuation passage, it can effectively prevent the smoke from entering the non-ignition tunnel.
Improved Filter Method for Feature Selection
Authors: Chen Yongle , Zhong Yiwen 
Published: August 2019

Abstract
To solve the problem of high data feature dimension in intrusion detection, a hybrid feature selection method has been proposed to reduce the feature dimension. This approach combines the filter and sequence floating forward search methods. Firstly, the original feature series is sorted by different filter methods, and the top ranked features are selected as the next original feature set. Based on this, the sequence floating forward search method is used to select the optimal feature subset with the Support Vector Machine (SVM) as the classifier. The method can avoid the selection and screening of the features based on the threshold and the evaluation value of single feature and categorical variable. Thereby the high evaluation characteristics obtained by the Filter method may be complementary to the low evaluation characteristics. The result shows that the proposed method can not only effectively reduce the number of features, but also can achieve a better classification performance.

Abstract
In order to effectively map more and more complex application tasks to the network on chip processing unit to complete the related tasks with less energy consumption, a new low power mapping method with a combination of genetic algorithm and tabu search algorithm is proposed. The method makes full use of the powerful global search ability of the genetic algorithm, and combines the local search ability of the tabu search and the prominent mountain turning features to compensate for the weak local search ability and premature defects of the genetic algorithm, so as to achieve better low power consumption effect on NoC. The experimental results show that under the same experimental platform and power consumption model, the new algorithm has a great energy efficiency improvement compared with the early genetic algorithm, and has energy efficiency advantages compared with the later improved MGA and AGA algorithms.
