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focuses on the impact of road environmental factors on road traffic accidents and analyzes the research results of historical documents.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.

A composite 3D-2D visual surface defects inspection scheme based on combining active 3D visual inspection with 2D image texture extraction is presented for steel bar intelligent manufacturing. The active 3D visual inspection method is used to detect the surface defects with poor contrast; the 2D image texture extraction method is used to detect the surface defects with tiny width. The variable defects can be identified through fusion of the acquired 3D and 2D information of steel bar. The fundamental derivation of composite 3D-2D visual inspection is given. The experimental results validate and demonstrate the feasibility of the proposed approach.

In view of the diversified characteristics of programming languages used by many current data processing algorithms, we have built an integrated platform based on Javaweb whose methods are developed by multiple programming languages. In this article, we discussed the application of some programming languages in data processing algorithms, and how to build a mixed programming environment of Java and other languages. By adopting Java and other multi-language mixed programming methods, we have carried out the design of the business logic layer of the integrated platform for the realization of multiple programming languages, which overcomes the lack of support of the Java programming language in data processing algorithm programming. It meets the needs of users who only need to use the integrated platform to quickly run different methods written in multiple languages. Application examples and results show that the method of using Java and other languages to build integrated Web projects is efficient and feasible.
