An optimal design of completely open permanent magnet MRI
Yao, Ying-Ying,Koh, Chang-Seop 충북대학교 컴퓨터정보통신 연구소 2004 컴퓨터정보통신연구 Vol.12 No.3
A completely open magnet geometry satisfies the requirement of a MRI system for the surgical procedure. This paper presents a new flexible design method to facilitate the construction of a completely open MRI magnet by combining the magnetic dipole pair model and optimization algorithm. A numerical implementation shows that the method provides a main magnetic field with sufficient homogeneity and strength at the imaging region, which is defined outside of the magnet structure, and minimizes the cost of the MRI equipment

A general solution to structural performance of pre-twisted Euler beam subject to static load
Ying Huang,Chang Hong Chen,Leon M. Keer,Yao Yao 국제구조공학회 2017 Structural Engineering and Mechanics, An Int'l Jou Vol.64 No.2
Based on the coupled elastic bending deformation features and relationships between the internal force and deformation of pre-twisted Euler beam, the generalized strain, the equivalent constitutive equation and the equilibrium equation of pre-twisted Euler beam are developed. Based on the properties of the dual-antisymmetric matrix, the general solution of pretwisted Euler beam is obtained. By comparison with ANSYS solution by using straight Beam-188 element based on infinite approach strategy, the results show that the developed method is available for pre-twisted Euler beam and also provide an accuracy displacement interpolation function for the subsequent finite element analysis. The effect of pre-twisted angle on the mechanical property has been investigated.

As an extremely destructive accident, progressive collapse is defined as the spread of an initial local failure from element to element, resulting eventually in the collapse of an entire structure or disproportionately large of it. To prevent the occurrence of it and evaluate the ability of structure resisting progressive collapse, the nonlinear static procedure is usually adopted in the whole structure design process, which considered dynamic effect by utilizing Dynamic Increase Factor (DIF). In current researches, the determining of DIF is performed in full-rigid frame, however, the performance of beam-column connection in the majority of existing frame structures is not full-rigid. In this study, based on the component method proposed by EC3 guideline, the expression of extended endplate connection performance is further derived, and the connection performance is taken into consideration when evaluated the performance of structure resisting progressive collapse by applying the revised plastic P-M hinge. The DIF for structures with extended endplate beam-column connection have been determined and compared with the DIF permitted in current GSA guideline, the necessity of considering connection stiffness in determining the DIF have been proved.

Ying Huang,Chang Hong Chen,Haoran Zou,Yao Yao 국제구조공학회 2019 Structural Engineering and Mechanics, An Int'l Jou Vol.69 No.5
Based on the displacement general solution of a pre-twisted Euler-Bernoulli beam, the shape function and stiffness matrix are deduced, and a new finite element model is proposed. Comparison analyses are made between the new proposed numerical model based on displacement general solution and the ANSYS solution by Beam188 element based on infinite approach. The results show that developed numerical model is available for the pre-twisted Euler-Bernoulli beam, and that also provide an accuracy finite element model for the numerical analysis. The effects of pre-twisted angle and flexural stiffness ratio on the mechanical property are also investigated.

Previously less notable behind the primary market, the pre-owned luxury market has grown rapidly during the past five years as luxury resale has become a new normal. This market presents some new challenges that do not apply to the traditional luxury market, yet limited research explores it. This paper fills this gap by investigating information disclosure and pricing effects in pre-owned luxury product promotion in the digital market. Analysis of a unique dataset from a leading luxury resale online platform suggests that providing more information through visual cues reduces information asymmetry and facilitates transactions, but the effect is moderated if pre-owned products are in newer conditions. High prices also have an overall negative effect on sales, but the effect is moderated among newer products because they provide higher price-prestige value. Managerial implications to sellers and the platform are discussed.
The linear elastic stiffness matrix model analysis of pre twisted Euler Bernoulli beam
Ying Huang,Haoran Zou,Chang Hong Chen,Songlin Bai,Yao Yao,Leon M. Keer 국제구조공학회 2019 Structural Engineering and Mechanics, An Int'l Jou Vol.72 No.5
Based on the finite element method of traditional straight Euler-Bernoulli beams and the coupled relations between linear displacement and angular displacement of a pre-twisted Euler-Bernoulli beam, the shape functions and stiffness matrix are deduced. Firstly, the stiffness of pre-twisted Euler-Bernoulli beam is developed based on the traditional straight Euler-Bernoulli beam. Then, a new finite element model is proposed based on the displacement general solution of a pre-twisted Euler-Bernoulli beam. Finally, comparison analyses are made among the proposed Euler-Bernoulli model, the new numerical model based on displacement general solution and the ANSYS solution by Beam188 element based on infinite approach. The results show that developed numerical models are available for the pre-twisted Euler-Bernoulli beam, and which provide more accurate finite element model for the numerical analysis. The effects of pre-twisted angle and flexural stiffness ratio on the mechanical property are investigated.

Yao Wang,Ying Yao,Cheol Park 한국경영정보학회 2010 한국경영정보학회 학술대회논문집 Vol.2010 No.1
The research examines the influence of CSII, using experience of eWOM and perceived eWOM credibility on eWOM effect, and the relationships among these factors in the specific atmosphere in China. These relationships were tested by AMOS with the data from a questionnaire survey in Beijing and Qingdao. As an important result, it is the first time showing that CSII is a root cause to influence eWOM effect and consumers’behavior. Also there were significant relationships among using experience of eWOM, perceived eWOM credibility and eWOM effect. The findings provide several managerial recommendations for online communication strategy in China.
