Investigation on Mechanism of Altitude Characteristic for Air-breathing Pulsed Laser Thruster

引用

Chinese Journal of Aeronautics 2010年第1期23卷 33-38页

作者： Hong Yanji,wen ming,cao Zhengrui Department of Basic Theories,Academy of Equipment Command & Technology,Beijing 101416,China Department of Basic Theories Academy of Equipment Command & Technology Beijing 101416 China

Altitude characteristic is of great importance for studying when an air-breathing pulsed laser thruster works in the dense atmosphere condition of 0-30 km altitude. The experimental findings all over the world show that the similar relationship between impulse coupling coefficient and altitude. According to strong explosion theory and an ideal gas model,a dimensionless factor indicating energy law of similitude is introduced,and formula of impulse coupling coefficient is deducted. Then theoretical study of altitude characteristic is carried out and mechanism of altitude characteristic is further explained. The results indicate that there is a maximum value of impulse coupling coefficient if the dimensionless factor equals to 0.41 in theory, and whether the phenomena of maximum appear or not depends on the range of the dimensionless factor related to altitude. As to a conical nozzle with the fixed length of 120 mm, the relationship between the sonic velocity and the dimensionless factor causes the maximum phenomenon at the altitude of about 12.5 km,and maximum theoretical impulse coupling coefficient is also found in the experimental investigations. The mechanism of altitude characteristic for air-breathing pulsed laser thruster is discovered in this article, which will provide reference for further research on altitude characteristic.

Sparse fast Clifford Fourier transform

引用

Frontiers of Information Technology & Electronic Engineering 2017年第8期18卷 1131-1141页

作者： Rui WANG Yi-xuan ZHOU Yan-liang JIN wen-ming cao School of Communication and Information Engineering Shanghai University Shanghai 200444 China College of Information Engineering Shenzhen University Shenzhen 518060 China Department of Electrical and Computer Engineering University of Missouri Columbia 65211 USA

The Clifford Fourier transform （CFT） can be applied to both vector and scalar fields. However, due to problems with big data, CFT is not efficient, because the algorithm is calculated in each semaphore. The sparse fast Fourier transform （sFFT） theory deals with the big data problem by using input data selectively. This has inspired us to create a new algorithm called sparse fast CFT （SFCFT）, which can greatly improve the computing performance in scalar and vector fields. The experiments are im- plemented using the scalar field and grayscale and color images, and the results are compared with those using FFT, CFT, and sFFT. The results demonstrate that SFCFT can effectively improve the performance of multivector signal processing.

Natural Science 2010年第1期2卷 49-53页

作者： wen-ming cao Ning Li 不详

Though manifold learning has been success-fully applied in wide areas, such as data visu-alization, dimension reduction and speech rec-ognition;few researches have been done with the combination of the information theory and the geometrical learning. In this paper, we carry out a bold exploration in this field, raise a new approach on face recognition, the intrinsic α-Rényi entropy of the face image attained from manifold learning is used as the characteristic measure during recognition. The new algorithm is tested on ORL face database, and the ex-periments obtain the satisfying results.
