Objective: To compare the signals of pulse — diagnosis of healthy volunteer in different times in one day. Methods: After collecting the pulse waves of 42 healthy volunteers in 4 specific periods in one day, do pretreatment, parameter extracting basing on harmonic fitting, modeling, and identification by unsupervised learning and supervised learning with cross-validation step by step for analysis...
Objective: To compare the signals of pulse-diagnosis of 2 kinds of liver disease patients: Fatty Liver Disease (FLD) and Cirrhosis. Methods: After collecting the pulse waves of patients with Fatty Liver, Cirrhosis, we do pretreatment, parameter extracting basing on harmonic fitting, modeling, and identification by unsupervised learning and supervised learning with cross-validation step by step for...
Objective: To build a viable method to analyze the Pulse-diagnosis signals by the combination of unsupervised learning and supervised learning. Methods: After collecting the pulse waves of patients with chronic obstructive pulmonary disease (COPD) and healthy volunteers, we do pretreatment, parameter extracting basing on harmonic fitting, modeling, and identification by unsupervised learning Principal...
Objective: To study the features in the pulse waves of women during pregnancy. Methods: To collect the pulse waves of pregnant women in different stage and compare them with normal women's. We choose continuous cycles waves with different period length and then do the LSQ regression by 12 harmonics fitting to build mathematical model and extract 193 parameters after pretreatment, then do classification...
The public key encryption with keyword search (PEKS) scheme recently proposed by Boneh et al enables one to search encrypted keywords without compromising the security of the original data. In Joonsang's paper, they proposed a important issue of refreshing keyword in PEKS. In view of the server may memorize trapdoor and reveal something about the keyword, we divide the time into several time zone...
The aim of higher education is to cultivate adaptive compound talent. And the classroom-teaching quality has profound social effect. Therefore, there exists practical significance to analyze systematically the factors of classroom-teaching quality and evaluate it. This paper presents a classroom-teaching quality system based on system engineering theory and method, in which we use AHP(analytic hierarchy...
