A Perceptually Motivated Active Noise Control Design and Its Psychoacoustic Analysis
Hua Bao,Issa M.S. Panahi 한국전자통신연구원 2013 ETRI Journal Vol.35 No.5
The active noise control (ANC) technique attenuates acoustic noise in a flexible and effective way. Traditional ANC design aims to minimize the residual noise energy, which is indiscriminative in the frequency domain. However, human hearing perception exhibits selective sensitivity for different frequency ranges. In this paper, we aim to improve the noise attenuation performance in perceptual perspective by incorporating noise weighting into ANC design. We also introduce psychoacoustic analysis to evaluate the sound quality of the residual noise by using a predictive pleasantness model, which combines four psychoacoustic parameters: loudness, sharpness, roughness, and tonality. Simulations on synthetic random noise and realistic noise show that our method improves the sound quality and that ITU-R 468 noise weighting even performs better than A-weighting.
THE DEFICIT AT RUIN IN THE SPARRE ANDERSEN MODEL WITH INTEREST
Bao, Zhen-Hua,Ye, Zhong-Xing 한국전산응용수학회 2007 Journal of applied mathematics & informatics Vol.23 No.1
In this paper, we consider the Sparre Andersen risk model modified by the inclusion of interest on the surplus. By using the techniques of Cai and Dickson [Ins.: Math. Econ. 32(2003)], we give the functional and also the exponential type upper bounds for the tail probability of the deficit at ruin. Some special cases are also discussed.

A vehicle system motion decoupling control method was proposed to address challenges in controlling articulated heavyvehicles (AHVs). The method, based on diff erential geometry theory, focused on distributed electric drive AHVs. Its objectivewas to separate the highly nonlinear and strongly coupled dynamics system into two relatively independent subsystems:longitudinal and lateral motions. Additionally, a robust controller was designed to improve the vehicle’s resistance toexternal disturbances like side winds. Simulation tests using a TruckSim model of a distributed electric drive AHV showsignifi cant improvements compared to vehicles without decoupling control. The rearward amplifi cation (RA) is reducedby 4.5%, the longitudinal velocity deviation by 67.5%, and the yaw rate deviation by 69.7%. The vehicle also demonstratesenhanced stability when subjected to strong breeze disturbances. To validate the control performance in real-time systems,the hardware-in-the-loop tests were conducted, which confi rms the eff ectiveness of the proposed control approach in practicalapplications.
ASYMPTOTIC DISTRIBUTION OF THE DISCOUNTED PROPER DEFICIT IN THE DISCRETE TIME DELAYED RENEWAL MODEL
Bao, Zhen-Hua,Wang, Jing Korean Mathematical Society 2011 대한수학회보 Vol.48 No.2
In this paper we consider the discrete time delayed renewal risk model. We investigate what will happen when the distribution function of the discounted proper deficit is asymptotic in the initial surplus. In doing this we establish several lemmas regarding some related ruin quantities in the discrete time delayed renewal risk model, which are of significance on their own right.

Based on the previous research and the investigative data avail-able in the pasture, the paper expounds that the marriage and fam-ily of the Ewenki ethnic group are tending to the sense of national identity, and delineates that the distinction of the Ewenki ethnic group is gradually confused because of the overwhelming trends of modernization, in addition, socialization has changed the mode of ethnic group identity obtained through marriage and family relations.
