Secure and Efficient Distributed Matrix Multiplication Based on Polynomial Coding

Xiaowen Fan, Yunfeng Zhang, Tinghe Zhang, Qiang Wang

Matrix multiplication is a fundamental computational operation widely used in various engineering applications. To accelerate large-scale matrix multiplication, computing tasks are commonly outsourced to distributed servers or cloud platforms. However, the involvement of untrusted nodes brings significant security risks. To address these …

PriWildMatch: Privacy-Preserving Flexible Wildcard Pattern Matching In The Cloud

Yunfeng Zhang, Xiaowen Fan, Haoyan Huang, Qiang Wang

Privacy-preserving wildcard pattern matching enables data owners to outsource textual data to the cloud while allowing users to perform flexible queries without disclosing sensitive information. Existing solutions typically support either single-character or multi-character wildcards but are predominantly designed for single-server settings. The …

Design and optimization of equal gradient thin-walled tube: Bionic application of antler osteon

P. Huo, Xiaowen Fan, Xin Yang, Jianping Li et autres

To improve the crashworthiness and energy absorption of thin-walled tube structures, a bionic thin-walled tube was designed based on the structural characteristics of antler osteon and the principle of structural bionics and had the same inner and outer diameters and the same …

Oblique impact resistance of a bionic thin-walled tube based on antles osteon

P. Huo, XU Shucai, Xiaowen Fan, LI Jian-ping et autres

Some achievements have been made in the study on mechanical properties of antler, but they have not been applied in engineering practice, especially in the study of thin-walled tubes similar to antler crashworthiness. In order to improve the crashworthiness and energy absorption …

Design and crashworthiness analysis of thin-walled tubes based on a shrimp chela structure

Yang Xin, Xiaowen Fan, XU Shucai, Huang Han et autres

In order to improve the crashworthiness of thin-walled tubes, the multi-cell bionic thin-walled tubes based on a shrimp chela structure were designed by the principle of structural bionics. By taking the cell number (2−6) and the impact angle (0°, 10°, 20°, 30°) …

Image De-Noising with Lifting Wavelet Based on Edge Detection

Xiaowen Fan

Edge information is the most important high frequency information of a digital image.Therefore,the key to de-noising is to maintain more edge information in the processing of de-noising.Thus comes out the idea of this paper.We present a new image de-noising scheme:Image de-noising with …

Non-Linear Analysis of Tunable Compression Bushing for Stabilizer Bars

Xiaowen Fan, Hai Bing Cai, Shan Lin, L. N. B. Gummadi et autres

Stabilizer bars in a suspension system are supported with bushings by a frame structure. To prevent the axial movement of the stabilizer bar within the bushing, several new stabilizer bar-bushing systems have been developed. The new systems introduce permanent compressive force between …
