With the improvement of people’s living standards, the food safety issue occurs frequently. How to identify all kinds of risks, evaluate these risks scientifically and manage the risk control effectively are the challenge for each sully chain manager and the relevant researchers. In order to reduce the occurrence of the food safety issues and ensure the quality of the people’s life, it is necessary to evaluate the food safety. Based on the food supply chain safety evaluation model, this paper uses AHP fuzzy integrated evaluation method with a new scale to evaluate food supply chain safety risk. The paper provides reference to ensure the safety of the food supply chain.

Narrating Oppressions against the Chinese “New Woman”: Mei Niang on Japanese Colonial Domination

WANG Xiaoping 이화여자대학교 아시아여성학센터 2012 Asian Journal of Women's Studies(AJWS) Vol.9 No.4

In this paper I look into the works of Mei Niang (1920-2008), the most famous writer in the Japanese-dominated puppet-state of Manchuria, to examine the practice of literary creation as a critical intervention against colonial domination. I find here that the writer ingeniously shows that Manchurian women faced a dual peril: apart from the conservative ideal about woman as “good wife, wise mother” promoted by the Japanese, there was another one regarding the radical notion of the “free-willed” woman. In addition, owing to the influence of progressive left-wing thought, the writer also broadened her horizon to include the lives of the downtrodden as subjects of her writing, which added a humanitarian dimension to her concerns regarding the destiny of women.

Xiaoping Jiang,Xiang Gao,Ziting Wang,Lele Wang 한국유체기계학회 2021 International journal of fluid machinery and syste Vol.14 No.3

Based on the pressure parameters of the turbine, the operation condition of the turbine is determined. Based on the input data, the operation condition of the turbine is predicted by the long short-term memory network. Firstly, the identification model of BP neural network method is established to identify the specific working conditions by using the historical values obtained in the practical engineering application. Then, according to the correlation between the measuring points, the multiple time series long short-term memory network prediction model (LSTM) is constructed, and the state trend of the hydraulic turbine unit under this condition is predicted. The corresponding punishment factors are calculated by using the prediction data of each measuring point and the threshold value of the prediction band, which are mapped into the radar chart Finally, an anomaly early warning system with flexible early warning rules based on equipment deviation index is proposed. Through the experimental analysis, the validity of the long short-term memory network prediction model and the radar graph model for calculating the deviation degree of the equipment is verified, and the advanced warning for the abnormal state of different acquisition points under different working conditions is realized, which provides a new method for the abnormal prediction and fault diagnosis of the hydraulic turbine.

Improved Channel Estimation Algorithms based on a Proposed Signal Model for PUCCH Format 3 in LTE-A

Xiaoping Zeng,Ya Wen,Zhiming Wang,Yuemei Jin 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.1

SORTD (Space Orthogonal-Resource Transmit Diversity) has already become a better way of transmit diversity for PUCCH format 3 in LTE-A [1]. SORTD technology lies in the characteristic that each antenna port transmits signal by using different cyclic shift [2] to make orthogonal each other. Using the SORTD’s feature of incoherence in different antennas, this paper proposes a special form of signal model. Based on this proposed model, we propose a low complexity channel estimator based on LS and cubic spline interpolation, and then we put a LS and DCT algorithm to improve the interpolation performance. Finally, for more accurate estimator we drive the third approach based on MMSE and DCT. A series of theoretical researches and simulation results show that all of them are suitable for the proposed signal model even in the environment of high-speed movement; especially the algorithms with DCT have a better performance.

Management of science & technology enterprise incubator is complicated with much uncertainty. Its performance is hard to be measured accurately. Therefore, this paper analyzes key factors that influence the management performance evaluation of incubators and constructs a management performance evaluation system. It proposes an improved extension membership degree evaluation model of science & technology enterprise incubator based on extension theory. This model puts in place extension distance and extension side-distance of management performance evaluation indicator and works out corresponding extension correlation function and weighted extension membership degree. Through a case study, the model and the algorithm are proved to be effective and feasible.

Mechano-Chemical Modification of Waste Rubber Powder with 2-Mercatobenzothiozole and 3-Aminopropyltriethoxysilane

Xiaoping Wang,Jianghua Du,Xin Zhang,Deming Jia 한국고분자학회 2018 Macromolecular Research Vol.26 No.5

A mechano-chemical modification process for waste rubber powder (WRP) was investigated in this paper. 2-Mercatobenzothiozole (accelerator M) was introduced as a peptizer to improve plasticity of WRP, and 3-aminopropyltriethoxysilane (silane coupling agent KH550) was used as a surfactant to further modify the surface of plasticized rubber powder (PRP) to improve interfacial bonding with epoxidized natural rubber (ENR). Infrared spectrums showed that the WRP generated more oxygen-containing groups by mechanical forces in the presence of accelerator M and then grafted amino groups with KH550. The mechano-chemical process with accelerator M changed the structure of WRP obviously shown by sol fraction and microstructure of PRP, which increased the mechanical properties and crosslink density of full rubber powder vulcanizates. After further modified by KH550, the modified rubber powder (MRP) had a positive chemical interfacial bonding with ENR, changing the fracture surface and improving the mechanical properties of vulcanizates. The cure characteristics of the vulcanizates also illustrated that accelerator M and KH550 participated in the vulcanization process increasing the curing efficiency. The best mechanical properties of ENR/MRP vulcanizates were better than the neat ENR vulcanizates. It indicated that the mechano-chemical process with accelerator M and KH550 will be a potential method to reclaim WRP.

Narrating Oppressions against the Chinese "New Woman" : Mei Niang on Japanese Colonial Domination

The memory and experience of a workwoman: How do Chinese workers spend their lives in Weaving Girl (2008)

WANG Xiaoping 이화여자대학교 아시아여성학센터 2016 Asian Journal of Women's Studies(AJWS) Vol.22 No.4

The film, Weaving Girl, focuses its camera upon laid-off workers who lost their jobs during the time of the Chinese government’s vehement neoliberal reforms following the 1990s. The narrative framework takes the triangular relationship of a woman and her two lovers. On the surface, it narrates a “tragic” story of a passionate woman, which seemingly is a reflection of the unfortunate destiny of the Chinese working woman in the era of reform; and there is a certain intersection between class and gender. However, after a careful examination of its narrative structure, the paper suggests that her tragedy to a large extent is merely a projection of the elite’s imagination regarding the working class, making it a biased and partial representation of the fortune of this unfortunate group in general and the female workers in particular. Furthermore, this narrative bypasses the really deplorable aspects of underprivileged people in contemporary China. Essentially, then, the plotline merely makes “fate” and the woman’s capricious character to be the scapegoats, but avoids exploring the neoliberal reform agenda which is the true cause of the tragedies of (female) workers, in which the protagonist’s own story is but a minor one. From this perspective, the movie is anti-feminist in its core under the surface of a pro-female stance. The merits and faults of the movie provide an inspiring lesson for future feminist interventions.

Space Deformation of Parametric Surface Based on Extension Function

Wang, Xiaoping,Ye, Zhenglin,Meng, Yaqin,Li, Hongda Society for Computational Design and Engineering 2002 International Journal of CAD/CAM Vol.1 No.1

In this paper, a new technique of space deformation for parametric surfaces with so-called extension function (EF) is presented. Firstly, a special extension function is introduced. Then an operator matrix is constructed on the basis of EF. Finally the deformation of a surface is achieved through multiplying the equation of the surface by an operator matrix or adding the multiplication of some vector and the operator matrix to the equation. Interactively modifying control parameters, ideal deformation effect can be got. The implementation shows that the method is simple, intuitive and easy to control. It can be used in such fields as geometric modeling and computer animation.

Cloud computing has the advantages of low cost, large scale, general and scalable. In all areas of the social life and the economic life, the cloud computing is widely used. And the emergence of the cloud computing is another revolution in the information society. With the rapid development of e-commerce, the combination of e-commerce and cloud computing has been proved to be a win-win combination. But, there still are many problems of the e-commerce in the cloud computing environment, especially in logistics. In this paper, we establish the e-commerce logistics evaluation system in the cloud computing. And we use the e-commerce logistics evaluation method to evaluate the logistics in the cloud computing based on the improved entropy method. Finally, the experiments show that the proposed method can be effectively applied to the evaluation of e-commerce logistics in the cloud environment and the evaluation results are objective and effective.
