Source localization based on time delay estimation in complex environment by Da-wei ZHANG, Chang-chun BAO, Bing-yin XIA

“…In order to improve the performance of source localization in noisy and reverberant environments,a novel time delay estimation (TDE) method was proposed.This method is called acoustical transfer function ratio based on statistical model (ATFR-SM).In the proposed algorithm,the noise reduction method based on the statistical model was adopted to reduce the effect of noise on acoustical transfer Function (ATF).In the ATF method,the power spectral density (PSD) was smoothed and whitened to reduce the effect of reverberations.voice activity detection (VAD) was used to distinguish the speech period from the noise period,and the TDE was performed in the speech period to improve the estimation accuracy.Moreover,the proposed TDE method and the linear closed-form method for source localization were combined to constitute a source localization system.The results of performance evaluation show that,in both the noisy and reverberant conditions,the lower percentage of abnormal points (PAP) and lower root mean square error (RMSE) can be achieved by the proposed TDE method than those of the reference methods.Meanwhile,the source localization has higher accuracy than the reference methods.…”

Common Ways to See Differently: Race, Mestizaje, and Criollismo as Seen by Blind People in Chile and Venezuela by Luis Angosto-Ferrández

“…It demonstrates that visually perceived markers are not self-evidently constitutive of race as a social category. Participants show sound knowledge of racialized categories but also reveal significant differences in the identification of racial markers and in the way that race informs their understandings of mestizaje and criollismo in Chile and Venezuela. …”

Rehabilitation Legislation of Disabled Persons in the View of Health Rights by Juan ZHANG

“…In consideration of the relationship between medicine and law, the article points out that the concept of the health right in the civil law should be extend firstly; the health rights which have the dual nature with civil rights and basic rights should be recognized secondly; because of the attributes of their basic rights, the health rights should be written in the constitution thirdly; at last, based on the modern concept of rehabilitation, the disabled persons who want to realize their health rights need to pay attention to the legislation of social law, especially the community rehabilitation, and the establishment and improvement of social insurance'system. …”

Matching and Optimization for the Parameter of Electric City Vehicle Powertrain by Li Wenwen, Sun Houhuan, Xu Xiaowen

“…Under the double pressures of energy crisis and environmental problems,the governments and the automobile enterprises have paid much attention to the pure electric vehicle which has advantages of zero emission,low noise and wide range of energy sources.Electric car is not very different from conventional cars,whether in the main structure or in the appearance.The main change is made in terms of drivetrain.Taking the pure electric city car as our research target,the power transmission system parameter is analyzed and designed,according to the vehicle parameters,power and economy requirements,the vehicle power system parameter is matched.The matched parameters of power system preliminarily is optimized from improving the transmission efficiency,taking the shortest time of acceleration and working conditions driving range maximum as optimization goal.The fitness function of transmission speed ratio is constituted of objective function and constraints condition by using a penalty function.The optimization is carried out by genetic algorithm,the optimal parameters of power system are obtained.…”

Opérations traductives dans les processus créatif et de conception en design by Sophie Fétro

“…The article thus proposes to distinguish three types of translation situations and to question what the translation methods put in place, invented or deduced from the techniques used, can allow on the creative level, leading to the belief that it is the set of translation operations that constitutes the creative work of designers. It is by distinguishing three types of translation that this article will consider the notion and act of translation in the field of conception and design: 1/ figurative and three-dimensional translations; 2/ matrix and graphical translations; 3/ software and hardware translations. …”
