This paper proposes a novel bandgap voltage reference with an accurate curvature compensation technique for completely compensating the thermal nonlinearity of the emitter-base voltage. With VIS 0.15 standard CMOS process, the proposed bandgap voltage reference circuit achieves temperature coefficient of 1.03 ppm/°C over the temperature range from -55°C to 155°C with the supply voltage of 1.8V. In addition, the circuit achieves line regulation performance of 0.02%/V with the supply voltage from 1.8V to 3V and the power supply rejection (PSR) levels are 83dB, 77dB, 58dB at ultra-low frequency (

Bifurcation and stability analysis for a fractional-order gene regulatory networks with time delay is researched. Firstly, taking time delay as the bifurcation parameter, the Hopf bifurcation and stability conditions are established. Finally, a numerical example verifies the theoretical conclusion. It is showed that time delay can heavily effect the dynamics of the system and each order has a major influence on the creation of bifurcation simultaneously. © ISCIIA and ITCA 2018 - 8th International Symposium on Computational Intelligence and Industrial applications and 12th China-Japan International Workshop on Information Technology and control application.

In view of the problem that the packet information preempted netw ork resources in the process of transmission in the CAN bus,w hich leads to the low utilization of netw ork resources and the low accuracy of information transmission. Thus,a hybrid scheduling algorithm NM TS based on CAN bus is proposed,in the NM TS hybrid scheduling algorithm,the dynamic scheduling algorithm EDF is used to schedule hard real-time messages to solve the problem of low utilization of netw ork resources; the static scheduling algorithm RM S is used to schedule soft real-time messages and non real-time messages,so as to solve the problem of low accuracy of information transmission. By using M ATLAB softw are,the CAN netw ork model can be built,the EDF algorithm,RM S algorithm and NM TS algorithm are simulated. The experimental results show that the netw ork resources utilization is 90%,the packet loss rate is 0% of the NM TS algorithm. Therefore,The hybrid scheduling algorithm based on CAN bus NM TS has the characteristics of high netw ork resource utilization and high accuracy of information transmission,w hich w ill be very helpful for further research of CAN bus.

With the development of intelligent and netw orking technology in automobile,the malicious attacks against in-vehicle CAN netw orks are increasing day by day,and the problem of information safety in automobile is aggravated. In this regard,this paper analyzes the security loopholes and threats w hich the CAN bus faced,put forw ard a kind of anomaly detection algorithm for vehicle CAN bus. The method uses support vector machine algorithm to distinguish betw een normal message and abnormal message,so as to realize the CAN bus anomaly detection. Theoretical and experimental studies show that this method can effectively detect abnormal packets in the CAN bus w ith a detection rate of over 90%,w hich can effectively resist malicious attacks such as tampering and cheating on the vehicle CAN bus.

This research is aimed at the optimization of industrial water distribution technology. Through the establishment of water quality model, the parameters which have greater influence on the water quality are chosen. Then super structure model is established to set up the objective function and the constraint conditions. The best route of water supply and water supply is got. Finally the on-line correction technology is adopted to deal with the error included in the measurement data. The research is a research method for the general problem, and can be used for reference in the similar problems. © 2016 IEEE.
