Abstract: The security issues and problems surrounding the Internet of Things (IoT) and the Internet of Vehicles (IoV) are thoroughly examined in this article. It draws attention to the dangers of intra-vehicle attacks and the necessity of strong security measures. Examining vulnerabilities in both V2I and V2C contexts, the article highlights the risks that individual hackers face due to their global accessibility. It also covers the difficulties that cybersecurity faces from the rise of machine hackers that use AI and big data analytics. The notion of Heterogeneous IoT is presented, which is a promising field of study with a wide range of applications. The article discusses the difficulties that come with managing protocol proliferation, integrating new technologies, and resolving networking issues in the context of the larger Internet of Things. It is emphasized how crucial trust, security, and privacy are to the success of IoT systems. The systematic review approach used in the research adheres to the PRISMA framework and the Cochrane procedure. Finally, it offers design suggestions and future research directions based on expert analysis conclusions. The study highlights the necessity of taking preventative action to lessen dangers associated with IoV and IoT, offering insightful information about the status of IoT research now and opening the door for future security improvements.

Abstract: Logistics is primarily to address issues with whose functional, organizational, personnel and material means can be improved and optimize the entire course material flow businesses, which shall logistics integration business functions. Production logistics means a sum of logistical tasks and measures for preparation and execution of the production process. Includes all activities associated with material and information flows of raw materials, auxiliary and production materials from the warehouse to the production of raw materials and semi-finished goods from the warehouse and purchased parts through the various steps of the manufacturing process including all buffer stores, through the installation of the finished goods warehouse.

Abstract: In order to find information of interest and found valuable information resources in enrich Internet data. This paper describes a personalized recommendation system, personalized recommendation system is an intelligent recommendation system to help e-commerce site for customers to provide complete personalized shopping decision support and information services. for the User Rating data extreme sparseness, This paper presents nearest neighbor collaborative filtering algorithm based on project score predicted ,experiments show that this method can improve the quality of recommendation system.

Abstract: Fuzzy C-means (FCM) clustering algorithm is one of the widely applied algorithms in non-supervision of pattern recognition. However, FCM algorithm in the iterative process requires a lot of calculations, especially when feature vectors has high-dimensional, Use clustering algorithm to sub-heap, not only inefficient, but also may lead to "the curse of dimensionality." For the problem, This paper analyzes the fuzzy C-means clustering algorithm in high dimensional feature of the process, the problem of cluster center is an np-hard problem, In order to improve the effectiveness and Real-time of fuzzy C-means clustering algorithm in high dimensional feature analysis, Combination of landmark isometric (L-ISOMAP) algorithm, Proposed improved algorithm FCM-LI. Preliminary analysis of the samples, Use clustering results and the correlation of sample data, using landmark isometric (L-ISOMAP) algorithm to reduce the dimension, further analysis on the basis, obtained the final results. Finally, experimental results show that the effectiveness and Real-time of FCM-LI algorithm in high dimensional feature analysis.

Abstract: By using laser-diode as pumping source, a passively Q-switched Nd:YVO₄ laser with Cr⁴⁺:YAG saturable absorber is realized. Considering the Gaussian distribution of the pump beam and the oscillating laser intensity, the coupled rate equations of a LD-pumped passively Q-switched laser with Cr⁴⁺:YAG saturable absorber are given. The relations between the pulse width and the pump beam radius in the gain medium as well as the laser beam radius in the saturabe absorber are obtained from the numerical solutions of rate equations, and the theoretical calculations agree with the experimental results.

Abstract: The paper does the pretreating operation of palm print, the process of which includes lowpass filtering, histogram equalization, binarization processing, edge extraction, corner detection, rotating location and extraction of subgraph ROI. In images done with pretreating, translation and rotation phenomenon of noise level has almost been removed, which benefits the characteristic extraction and identification of palm print. And we finally demonstrate by experiments.

Abstract: According to the problems of slow weighing speed and low precision resulting from sticky foods caking in quantitative packing weighting, the mechanical structure, the circuit system and the software algorithm were designed in this paper. To improve the weighing speed and precision of sticky foods, the double-tube spiral feeding machine and a special structure of scale bucket were adopted in mechanical structure; a programmable AD8555 was used as weak signal amplifier of weighing sensor and a 32-bit microprocessor LP2134 was utilized as the core of the circuit system; the piecewise weighing method, FIR software filter and the differential algorithm are applied to send command to executive mechanism in program design.

Abstract: This paper an analysis of the present teaching of electric control system of the office building,the use of RF wireless communication technology combined with single chip microcomputer, using infrared technology, through the central control room for the entire teaching office lights and other electrical equipment for centralized, reasonable control; to ensure the stability of the system.

Abstract: The traffic signal lights control system automatically controls the statues of the intersection traffic lights and dispatch the traffic vehicles normally that traffic scheduling is an important system and it is the most basic and most important tools in city traffic management. Traffic lights control system made by single chip microcomputer technology has a single working model, low reliability, slow speed, and it can't modify or upgrade online, which is difficult to adapt to changes at different times of the traffic flow. This design of the dual mode of traffic lights control system intelligently controls each intersection traffic lights on and off time in the different period, which will improve the scheduling efficiency of road intersections. The design is based on FPGA with a digital display of traffic lights control system, compile the program design and simulation in Quartus II development environment, and ultimately download to EP2C35F672C6 chip of Altera Company. By the DE2 experiments test platform, the system has stable performance, simple operation, easy to maintenance, high reliability, strong expansibility and good refactoring.

Abstract: In order to against the uncertain disturbance of AC linear servo system, an H mixed sensitivity control method based on adaptive fuzzy control was putted forward in the paper. The controller is comprised of an adaptive fuzzy controller and a H robust controller, the adaptive fuzzy controller is used to approximate this ideal control law, H robust controller is designed for attenuating the approximation errors and the influence of the external disturbance. The experimental results show that this control strategy not only has a strong robustness to uncertainties of the linear system, but also has a good tracking performance, furthermore the control greatly improves the robust tracking precision of the direct drive linear servo system.
