TL;DR: It has being proved the HHT is an efficiency method to study the heart sound, S1 consists of two major high-frequency components, M1 and T1, and the abnormal bioprosthetic mitral valve generates higher frequency components than the normal one.
Abstract: According to the valvular theory, the vibrations affected by the mitral and tricuspid valves closure in early systole produce the first heart sound (S1). S1 usually includes many frequency components. Analysis of the first heart sound will be helpful to diagnose the clinic heart diseases. In this paper, a new method using the Hilbert-Huang Transform(HHT) was used to decompose S1 into a series of time-frequency atoms. By examining 30 cases of heart sound data, It has being proved the HHT is an efficiency method to study the heart sound, S1 consists of two major high-frequency components, M1 and T1,the abnormal bioprosthetic mitral valve generates higher frequency components than the normal one.

TL;DR: This paper researches machine learning by Lie group which has good mathematics configuration and advances some basic conceptions of machine learning (ML) based on Lie group and conceptions of learning based on dual space, and formed the basic learning theory frame based onLie group.
Abstract: Machine learning is a eternal problem in the researches of artificial intelligence. However, machine learning methods are short of systemic theoretic foundation at present and some preferable ones such as statistic learning theory are exploring ones. Therefore, this paper researches machine learning by Lie group which has good mathematics configuration advances some basic conceptions of machine learning (ML) based on Lie group and conceptions of learning based on dual space, and formed the basic learning theory frame based on Lie group. The theory frame can describe machine learning system by algebra and geometry methods. So that it makes a fine configuration for describing the procession of machine learning and makes up for the lack of other theories of machine learning. It can be believed that researches of machine learning could be profoundly influenced by these works.

TL;DR: The relation of humidity,dry-bulb temperature and damp bulb temperature was analysed and one calculation method which transforms surface problem into curve problem is brought up.
Abstract: Damp bulb method based on singlechip is studied.The relation of humidity,dry-bulb temperature and damp bulb temperature was analysed and one calculation method which transforms surface problem into curve problem is brought up.This calculation method not only is simple but also has high veracity. The result of test indicates that the humidity measure precision depends on mainly the temperature measure precision.

TL;DR: In this article, a distortion correcting method is used and combined with phase correlation method to get the initial rotation values of the all image pairs with overlap, and then the least gray value difference square sum function of the image pair with overlap is iteratively solved to get precise rotation value and distortion correction parameter.
Abstract: Fisheye image has wider view lens compared to ordinary image. Two to four fisheye images are enough to cover 360-degree horizontal and vertical field of view . However, ordinary registration method causes bad panoramic image because of serious distortion of fisheye images. In this paper, a distortion correcting method is used and combined with phase correlation method to get the initial rotation values of the all image pairs with overlap. Then the least gray value difference square sum function of the all image pairs with overlap is iteratively solved to get precise rotation value and distortion correction parameter.

TL;DR: The operating principles and the design scheme of the car license plate recognition system which consists of image processing, image segmentation, and used MATLAB to achieve simulation of the processing.
Abstract: A high recognition rate expressway license plate recognition system (CLPRS) is introduced in this paper. We propose the operating principles and the design scheme of the car license plate recognition system which consists of image processing, image segmentation. We used MATLAB to achieve simulation of the processing. The results express that this means is effectual. '
