Program Design for Treating Experimental data of Young Modulus

Based on physical knowledge, a program is designed and edited with computer language from a mathematical model. The program can be applied to calculate the Young modulus and its uncertain degree. The diagram and an example are given. Key words:Young modulus; uncertain degree; data; program; calculatemage coding$$$$ ZHAO Yao 1, WANG Hong xing 2, YUAN Bao zong 1 ( 1Institute of Information Science, Northern Jiaotong University, Beijing 100044, China; 2Naval Aeronautical Engineering Academy, Yantai 264001, China) Abstract: Slow compression speed is the greatest barrier for the practical use of attractor image coding, so how to speed up its compression procedure is a research hotspot now. In this paper, a fast algorithm for attractor image coding is proposed which uses fractal dimension to evaluate the matching degree of range blocks and domain blocks and therefore the time exhausting matching process of the tranditional fractal coding is greatly reduced. Meanwhile, bubble method and dichotomy are used to speed up the sorting and searching processes. Experimental results show that the speed of the scheme proposed in the paper is about 5 times as fast as traditional Jacquin's scheme.
