Road traffic is an important mode of transportation for daily travel. Traffic accidents cause tens of thousands of deaths every year. Studying the influencing factors in traffic accidents will help to discover the main causes of accidents and prevent the recurrence of similar accidents. Among the factors that caused the accident, the road environment factors played an important role. The paper focuses on the impact of road environmental factors on road traffic accidents and analyzes the research results of historical documents. Based on road traffic accident statistical annual report data, the study of the impact of road environmental factors on accidents in road traffic accidents provides a basis for ensuring driving safety and analyzing the factors affecting accidents.

The musculoskeletal model has been received great attention due to the ability to clinical treatment and disease analysis, animation, and humanoid robot control. Different software is used to perform that. However, most of them using cadaver data which may lead to unrealistic results. The paper introduces a simple model not only to find the kinematics of the lower limb but also to predict the tibiofemoral force. The markers trajectory for a subject is used to get the kinematics of the lower limb based on defining the anatomical frame at the joints and tracking cluster frames at each segment. Global optimization is used to overcome soft tissue artefacts (STA) based on the least square error between the measured marker position and its model. The dynamics of the lower is analyzed where the external force and moment affecting the knee are calculated and static optimization is used to predict the tibiofemoral force for the medial and lateral tibia compartments. The results are compared to in vivo data of the same subject to guarantee validity. The 1st and the 2nd peak for the medial tibia compartment are 1.33 ±0.17 BW, and 1.34± 0.08 BW whereas for the lateral tibia compartment are 0.125±0.04 BW, and 0.92±0.08 BW respectively. The model can be used to predict the tibiofemoral force and so controlling the human motion using a knee brace or exoskeletons.

The key for humans to maintain balance in complex environment is the ability to choose an appropriate balance strategy adaptively. To better understand the mechanism of balance recovery strategy selection, we aim to study the relation-ships between perturbation dependent response foot state and balance recovery strategy for velocity-controlled perturbations of different durations. Foot kinetic and kinematic data were measured simultaneously for distinguishing different state and strategy and find the thresholds under 10 compliant treadmill-controlled perturbations. Each condition was repeated for 10 times to find the relationships between heel-lifting frequency and stepping strategy. All experiment perturbation magnitudes were conducted randomly. The result shows that foot pressure distribution can easily identify heel-lifting foot state and step-ping strategy. The frequencies of HL of were always larger than SS frequencies and the boundary of HL is smaller than SS. Also, the rate of change for achieving heel lifting in ground re-action force distribution may indicate balance ability. This study reveals the influence of the change of human balance strategy on plantar pressure. In turn, that relationship can be used for human balance strategy identification, which could help control humanoid robot.

Most of the existing signature schemes of designated verifier are implemented by bilinear pairings. Due to the high computation of bilinear pairings, it is necessary to reduce the number of bilinear pairings properly to improve the efficiency of signature. At present, some researchers have begun to consider the use of discrete logarithm or elliptic curve to replace the calculation of bilinear pairs, so as to reduce the amount of calculation and improve the efficiency of the scheme. This paper designs a signature scheme of designated verifier based on discrete logarithm, and proves the security of the scheme under the oracle model.

With the development of science and technology, modern agriculture has made great progress, but frequent agricultural safety events seriously affect people's trust in agricultural production and even affect economic and social development. Therefore, it is very important to trace the origin of agricultural products. Blockchain, as a new technology in recent years, has been widely used in various source tracing fields due to its characteristics of decentralization, traceability, and non-tampering. This paper designs a tobacco source tracing system based on alliance chain. The system saves the source tracing information in the alliance chain to ensure the reliability and traceability of the tobacco source information. The system mainly includes three functions: the product information manager enters the source tracing information of the product through the management end, stores the source tracing information of the product with the alliance chain, and the user can view the source tracing information through the tracing app.

A state detection method of power equipment based on Binocular vision video is proposed. The power equipment video stream is obtained by binocular camera, and the inspection image is obtained by extracting the video key frames. The disparity map of the region of interest in the inspection image is calculated, and the distance information distribution is obtained from the disparity map. According to the distance information distribution, the status of electrical equipment is determined. Through the principle of binocular vision ranging, equipment status identification is realized, which provides a new method for the identification of substation equipment status, and realizes the rapid and accurate identification of power equipment status.

In this paper, we focus on the problem that the sound circuit keeps ringing when the countdown timer countdown to 0. To solve this problem, we have made many improvements. For the first time, we use Dingdong music chip to add Loudspeaker, after 10 seconds countdown, the loudspeaker "ding dong" stops three times; The buzzer is used for the second improvement, but the sound does not work normally, it sounds every 2 seconds, and finally it is successfully improved to make the buzzer stop automatically after ringing for a period of time as required by us. The paper gives the design schematic diagram, PCB diagram, and the actual circuit board display. Finally, the conclusion is summarized. The schematic diagram and PCB diagram improved for the first time with Ding Dong music chip and finally with buzzer can be directly applied because they have passed the experiment.
