To solve the problems of frequent changes of cloud storage data blocks and high audit overhead, a data agent-based dynamic data integrity verification scheme is proposed, which supports public verification and meets dynamic operation requirements. Fine-grained data-based signature methods have significant advantages in significantly reducing signature-related costs. Besides, users can set the number of sub-blocks according to their own needs in the application process, and the scalability also reaches a high level. Under the lattice-based cryptosystem, this scheme is much more efficient than the traditional one because it mainly uses linear computation. The security of this scheme is mainly related to the decimal integer solution on the lattice. High security can affect the resistance against quantum attack and has high application value.

Sorting is a classic problem in computer science. Different kinds of sorting algorithms are required in different application scenarios. With regard to the real-time data processing applications implemented on FPGA, a faster throughput and more resource efficient sorting algorithm is needed to complete the data sorting. And the pipelined implementation of sorting algorithm is essential for improving the overall throughput. In this paper, a serial comparison based iterative sort algorithm is proposed and its implementation on FPGA is elaborated. To take advantages of the parallel characteristics of FPGA, the pipelined sorting module is realized by concatenating multiple serial comparison sorting submodules. Compared to other sorting algorithms implemented on FPGA, the serial comparison based iterative sort algorithm has the merit of requiring fewer resource consumptions, consuming less executing time and generating faster overall data throughput. The algorithm and its pipelined implementation have been successfully applied to the median filter of OS-CFAR processing in millimetre-wave MIMO radar, and their performance have been validated.

This paper proposes a Tibetan text compression algorithm (TiCA), which is based on the fact that each Tibetan syllable is composed of one to seven components and each component has a unique Unicode encoding. First of all, through statistical analysis of 20G Tibetan text corpus, a fault-tolerant mapping dictionary is established and used as the dictionary of the TiCA. The TiCA then compresses the Tibetan text according to the mapping dictionary by mapping the original code to a single code. Finally, the experimental comparison shows that the Tibetan text compression algorithm proposed in this paper has achieved excellent results both in the compression rate and time consuming.

The motion accuracy of the system is directly affected by the vibration characteristics of the components. In this paper, the ball linear guides for high-precision mobile platforms for chip inspection equipment are taken as research objects, and their vibration characteristics are analyzed. Based on the theoretical analysis of the contact characteristics of the contact pair based on HertZ theory, the finite element analysis software was used to analyze the modal of the ball linear guide. Among them, the change of normal contact stiffness has a greater impact on the system modal. The material and structural characteristics of the contact pair are the main factors affecting the natural frequency of the system. The magnitudes of each mode and the first six natural frequencies are given. Based on Newtonian mechanics, a mathematical model of the collision between the ball and the returner is established, and the influence of the structural parameters on the collision force is analyzed. The impact of the turning radius on the impact force is negligible, and the initial relative speed, ball mass, and elastic modulus have a greater impact on the impact force. For the ball linear guide rails studied in this paper, the impact force of the ball on the system during the movement is less than 40N, and the vibration shock frequency is less than 7.5Hz. It lays the foundation for the follow-up compensation of the collision force by using the motor feedforward control method, and improves the system's motion accuracy and positioning accuracy.

In this paper, a wearable exoskeleton robot for upper limbs is developed, which requires a higher upper arm strength when weapons such as guns are controlled, ammunition and equipment materials are lifted. The overall design idea, mechanism principle, system composition, system performance and related tests are briefly introduced. The exoskeleton robot can be used for single soldier weapon control to improve shooting accuracy, and can also be used for upper limb overload jobs such as stretcher displacement and lift, self-propelled gun ammunition loading, carrier borne aircraft gun hanging and other equipment and materials lifting.

Focusing on the gear measured signal can not accurately reflect the fault characteristics due to noise interference, a novel way was introduced for gearbox fault recognition in the article. By using the rank-order morphological filter, the influence of noises was eliminated from the original signal. Then the ensemble empirical mode decomposition (EEMD) method was utilized for decomposition of the de-noised data. From these decomposition results, some useful components were selected and calculated the fuzzy entropy. Then the grey relation degree method was used to recognize different gear fault type. Recognition results express the effectiveness of the proposed method.

Wheel rotation parameter is one of the key parameters reflecting driving safety. The existing characteristic quantity of wheel rotation signal adopts an extraction method of wheel radial acceleration curve, by which the measurement range of wheel radial acceleration sensor is quite large, with low sensitivity and resolution ratio, which is difficult to express the true status of radial acceleration and extract characteristic quantity of wheel rotation signal accurately. This article proposes a new method to extract characteristic quantity of wheel rotation signal through the curve of tangential acceleration. To acquire the tangential acceleration signal by installing an acceleration unit on the wheel, apply wavelet packet to make wavelet de-noising on the wheel tangential acceleration signal and then extract the characteristic quantity of wheel rotation signal by STFT. The experimental results indicate that the measuring error of wheel frequency under experimental conditions is -0.79%. This new approach can realize the high-precision measurement on the characteristic quantity of wheel rotation signal, and make further efforts to monitor and evaluate wheel brake performance.
