As the economy is getting better and better, the masses are the basic consumption groups of the intelligent transportation system. For the vast number of manufacturers and operators, the masses are the resources they are trying to find. The research and development of high-tech products need time. It is necessary to adapt scientific research to the masses, so as to generate a continuous source of power and promote technological development. With the rapid development of network technology, the transmission of information through the network will certainly become a trend. Before the trip, first through the network to plan their own trip route;after the vehicle was stolen, the location of the vehicle was inquired through the positioning device. The new era of transmission of vehicle information through the network is taking the place of the old age of manpower scheduling step by step.

In order to acquire the normal gait parameters and variation rules, the fuzzy algorithm was introduced for processing experimental data. The effect of the normal subject's height and walking speed on the motion amplitude of the pelvis was chosen as an example, and the experimental study on the gait parameters of 30 males was completed. By analyze the experimental data the fuzzy rule and fuzzy inference chart were set up. The simulation analysis was implemented by the fuzzy toolbox of MATLAB software, and the experimental validation was carried out. The research results accord with the theoretical model. It illustrates the feasibility and accuracy of the fuzzy algorithm. This study has important application value in the fields of biomedical and rehabilitation engineering.

Routing, as one of the important problems in the field of robotics, is a complicated issue in real and dynamic environments. In this study, routing was simulated using Genetic algorithm and fuzzy logic. It was observed that the time consumed for reaching the destination in fuzzy logic was much less than the time spent in Genetic algorithm. Furthermore, the distance traveled by Genetic algorithm was less than the distance obtained from routing by fuzzy logic. Therefore, to determine the optimal path of motion, the hybrid fuzzy-Genetic method was used. In fuzzy logic, distance from the nearest obstacle and the angle difference with the target node were selected as the two node-to-node routing criteria. To reduce the traveled distance in the fuzzy method, the Genetic algorithm was used to optimally adjust the fuzzy rules table. In the simulation, the proposed method showed a relatively better performance than both mentioned algorithms in terms of distance and time. In the best case, the traveled distance from origin to destination in the hybrid fuzzy-Genetic method was reduced by 32% compared to fuzzy logic and the consumed time to reach the destination was reduced by 43% compared to Genetic algorithm.

In order to meet the automatic assembly requirements of large-size and large-torque threaded connection workpieces such as oil pipes and ammunition, a fuzzy prediction model for thread tightening is established by selecting tightening torque and rotation angle as characteristic quantities, and a new automatic tightening control method for large-torque threads is proposed. At the same time, an automatic tightening device for large torque threaded workpieces is designed for experimental verification. It has been proved that the method can meet the functional requirements of automatic screwing of large torque threads, the screwing torque of threads can reach 2320 Nm, the screwing process is stable and reliable, and has great engineering application value.

Liquid level as an important in the chemical industry and many other industrial production parameters, the measurement and control effect directly affects the quality of the product, so the liquid level control plays an important role in the industrial production. Because the liquid level of liquid level control system has nonlinear, big lag, outlet valve port mathematical model is difficult to accurately set up wait for a characteristic, the conventional incremental PID algorithm is difficult to obtain satisfactory control effect. To solve above problems, this paper designed the control using PLC, controlled by fuzzy controller, the form for the closed loop control system, in order to implement the constant of the liquid level. Simulation experiments show that the fuzzy PID control level, the system be able to complete the various automatic and manual pump start, stop, and no impact to switch, and fault alarm, a smooth transition.

Computer security has become an important part of the day today's life. Not only single computer systems but an extensive network of the computer system also requires security. In achieving the safety of the systems, an Intrusion Detection System (IDS) plays a significant role. IDS is a software that monitors the computer network and detects the suspicious activities that occur in the systems or network. The process of intrusion detection includes detecting intrusion. Intrusion is a suspicious activity attempted by the attacker. This paper presents a fuzzy-genetic approach to detecting network intrusion. Paper presents the results of the proposed system in terms of accuracy, execution time, and memory allocation. To implement and measure the performance of the system the KDD99 benchmark dataset is used. The KDD99 dataset is a benchmark dataset that researchers use in various network security researches. Genetic algorithm includes a development and collection that uses a chromosome like data structure and develop the chromosomes using selection, crossover and mutation operators. fuzzy rule sorts network attack data.
