        Is Social Quality Related to Subjective Well-Being in Shanghai? An Analysis of Economic and Social Structural Factors

        HAO YUAN,MAYANK-KUMAR GOLPELWAR 서울대학교 사회발전연구소 2012 Journal of Asian Sociology Vol.41 No.1

        Based on an empirical survey in Shanghai, this study tests the effects of four domains of social quality (SQ) viz. economic security, social inclusion, social cohesion, and social empowerment on subjective well-being (SWB). The results show that home ownership and income are important determinants of SWB, though the latter is not as strong a predictor of SWB as the former. Apart from the economic determinants, social cohesion (e.g., political trust) as well as social inclusion (e.g., involvement with social and cultural organizations) can influence people"s SWB to a high degree. Additionally, social alienation and loneliness are negatively related to SWB. Even the degree to which people can express themselves freely relates directly to their SWB level. Results also show that the more people see success as a result of self-effort, the higher their SWB level.

      • Mobile Cloud Computation Offloading Switch Based on Decision Value Model

        Hao.Yuan,Changbing. Li,Maokang. Du 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.9

        A method had been constructed for mobile cloud computation offloading switch based on decision value model. In this method, two important ratios had been built: one is the calculation ratio which are offloaded on a proxy server completed tasks time and at the mobile node completed tasks time. Another is the calculation ratio which is offloaded on proxy server completed tasks energy and at the mobile node completed tasks energy. And then, decision value function was produced by combining with these two ratios. Finally, consider the optimization switch problem of computing tasks between different proxy servers. Experimental results show that the proposed method has a smaller time consumption and energy consumption by comparing with random offloading switch and minimum time-based offloading switch, and battery remaining of mobile node can be used rationally.

        A Novel Precision Synchronization Control via Adaptive Jerk Control with Parameter Estimation for Gantry Servo System

        Hao Yuan,Ximei Zhao 제어·로봇·시스템학회 2023 International Journal of Control, Automation, and Vol.21 No.1

        This article presents a novel precision synchronization control method and corresponding control design using adaptive jerk control (AJC) with parameter estimation to improve the synchronous performance for gantry servo system with parametric variations and unknown disturbances. Initially, cross-coupled control (CCC) is provided to realize the synchronous cooperation of two parallel permanent magnet linear synchronous motors (PMLSMs), and the coupled system model is transformed into a state-space form. Consequently, the filtered errors based on synchronous error and position tracking error are established to simultaneously guarantee that both the synchronous error and position tracking error converge to zero asymptotically. Then, AJC is proposed to handle the uncertainty. More specifically, an adaptive feedback gain is involved in the AJC for improving the robustness, without requiring a priori knowledge of the uncertainty. A novel adaptation law is introduced to update the adaptive feedback gain. Moreover, a terminal attractor is incorporated into the adaptation law to improve the convergence even with noise. Therefore, the chattering phenomenon are significantly alleviated. Meanwhile, parameter estimation is employed to address the model parametric variations. Experimental results demonstrate the efficiency and superior performance of the precision synchronization control method.

      • Cellular Particle Swarm Scheduling Algorithm for Virtual Resource Scheduling of Cloud Computing

        Hao Yuan,Changbing Li,Maokang Du 보안공학연구지원센터 2015 International Journal of Grid and Distributed Comp Vol.8 No.3

        The virtual resource scheduling is an important topic in the field of cloud computing. Based on particle swarm scheduling algorithm, this paper introduces cellular automata theory to construct a new cellular particle swarm scheduling algorithm. This approach through mathematical modeling for virtual resource scheduling of cloud computing and complete the final search configuration based on directional optimization objective function. Experimental results show that the proposed method has more excellent scheduling performance, in the case of changes in resources, can be also kept stable scheduling balance.

      • CFD study of an iterative focused wave generation method

        Haoyuan Gu,Hamn-Ching Chen Techno-Press 2023 Ocean systems engineering Vol.13 No.1

        An iterative focused wave generation method is developed and implemented in a local analytic based Navier-Stokes solver. This wave generation method is designed to reproduce the target focused wave by matching the target amplitude spectrum and phase angle. A 4-waves decomposition scheme is utilized to obtain the linearised component of the output wave. A model test studying the interaction between different focused waves and a fixed cylinder is selected as the target for the wave generation approach. The numerical wave elevations and dynamic pressure on the cylinder are compared with the experimental measurement and other state-of-the-art numerical methods' results. The overall results prove that the iterative adjustment method is able to optimize the focused wave generated by a CFD approach.

        Investigation on the effects of blade thickness for a centrifugal rotary blood pump

        Haoyuan Li,Ming-Kui Zhang,Xianwu Luo,Qing-Yu Wu 대한기계학회 2023 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.37 No.2

        A centrifugal rotary blood pump was treated to investigate the effects of blade thickness by numerical simulation, where Reynolds averaged Navier-Stokes method coupling with k-ω SST turbulence model is applied. For comparison, five pumps were designed with different blade thickness distribution from the leading edge to trailing edge. The numerical methods were validated by the comparison of hydraulic performance between the simulation and the experiment for a test pump. Results showed that the thicker blade near leading edge suppresses the separation flow in blade-to-blade passage of pump impeller, and can improve hydraulic efficiency at low flow rate. On the other hand, the blade shape modification by trimming suction side near trailing edge is helpful to reduce the hydraulic loss by suppressing the flow mixing downstream impeller exit. Power loss analysis based on the simulated internal flow indicated that viscous dissipation of mean kinetic energy (VDKE) and turbulence kinetic energy production (TKEP) are main source terms contributing to power loss for the blood pump. The blade thickness near trailing edge changes the interaction between volute tongue and impeller blade, and the trimmed blade is helpful for decreasing the large values of VDKE and TKEP in pump volute compared with the conventional blade. The analysis further indicates that the blade modifications with thickness increment seem to slightly increase the degree of RBCs damage, and the effect of blade thickness on the hemolysis index of the blood pump should be carefully considered. The results are expected to be beneficial to the wide application of centrifugal rotary blood pumps.

        Y-Single Nucleotide Polymorphisms Diversity in Chinese Indigenous Horse

        Haoyuan Han,Qin Zhang,Kexin Gao,Xiangpeng Yue,Tao Zhang,Rui-Hua Dang,Xianyong Lan,Hong Chen,Chuzhao Lei 아세아·태평양축산학회 2015 Animal Bioscience Vol.28 No.8

        In contrast to high genetic diversity of mitochondrial DNA (mtDNA), equine Y chromosome shows extremely low variability, implying limited patrilines in the domesticated horse. In this study, we applied direct sequencing and restriction fragment length polymorphism (RFLP) methods to investigate the polymorphisms of 33 Y chromosome specific loci in 304 Chinese indigenous horses from 13 breeds. Consequently, two Y-single nucleotide polymorphisms (SNPs) (Y-45701/997 and Y-50869) and one Y-indel (Y-45288) were identified. Of those, the Y-50869 (T>A) revealed the highest variation frequency (24.67%), whereas it was only 3.29% and 1.97% in Y-45288 (T/-) and Y-45701/997 (G>T) locus, respectively. These three mutations accounted for 27.96% of the total samples and identified five Y-SNP haplotypes, demonstrating genetic diversity of Y chromosome in Chinese horses. In addition, all the five Y-SNP haplotypes were shared by different breeds. Among 13 horse breeds analyzed, Balikun horse displayed the highest nucleotide diversity (π = 5.6×10‒4) and haplotype diversity (h = 0.527), while Ningqiang horse showed the lowest nucleotide diversity (π = 0.00000) and haplotype diversity (h = 0.000). The results also revealed that Chinese horses had a different polymorphic pattern of Y chromosome from European and American horses. In conclusion, Chinese horses revealed genetic diversity of Y chromosome, however more efforts should be made to better understand the domestication and paternal origin of Chinese indigenous horses.
