The Research on the Effect of Consumer Internal Psychological Preference to the Retail Industry Inventory  [PDF]
Lina Fang, Yu Hou, Yangchen Chen
Journal of Service Science and Management (JSSM) , 2016, DOI: 10.4236/jssm.2016.95044
Abstract:
Supply chain inventory plays an increasingly important role in rising prosperity and flexible retail industry. The retail industry’s own characteristics determine the importance of the inventory. The inventory management has played an important role in reducing the cost of supply chain and the whole supply chain coordination and stability. This paper takes the consumer internal psychological preference as the starting point. Data are obtained through market research on consumer internal psychological preference and consumer sensitivity of the inventory. Based on the internal psychological preferences of consumers, the correlation among product quality, product price, and consumer behavior of the three potential variables is analyzed. This paper constructs the structural equation model of consumer behavior and inventory sensitivity, and puts forward the main issues and improvement measures to the retail industry inventory.
An Empirical Study Based on Supply Chain Supplier Evaluation System  [PDF]
Quan Qu, Lina Fang, Yu Hou
Journal of Service Science and Management (JSSM) , 2016, DOI: 10.4236/jssm.2016.95045
Abstract: Under the environment of supply chain, enterprises not only put forward higher request to the product itself, but also focus more on the supplier selection criteria. In the early stage of the supply chain construction enterprises, we will find that there are many outstanding suppliers to choose from; facing a large number of suppliers, an effective way of supplier evaluation is very important. In this paper, the principal component analysis method is applied in supplier evaluation index, by extracting the principal components of the multi index comprehensive evaluation, and quantitatively provides guidance and reference for the selection of suppliers for the enterprises in the supply chain.
Research on Accurate Information Pushing Based on Human Network  [PDF]
Meijie Yang, Yu Wang, Xiaorong Hou
Social Networking (SN) , 2017, DOI: 10.4236/sn.2017.62011
Abstract: Based on the social network analysis methods and human network, this paper randomly selected 44 students (31 males and 13 females) as the research objects, and it used the UCINET software to analyze the friendship between them of which 43 used WeChat and 44 used QQ, and it also used the tool Netdraw to visualize the network sociogram. By mining the four aspects of density, accessibility, centrality, block model, the results demonstrated that QQ social network and WeChat social network existed the phenomenon of small world, leaders and subgroups, and the key nodes of QQ human network were more than WeChat network. Through using the key nodes, it can push the precise and efficient information and improve the accuracy of information transmission and impact among network members.
The Exploration of Historical Blocks’ Protection and Renovation Based on the Theory of City Image  [PDF]
Hui Yu, Shubei Hou, Liang Lang
Current Urban Studies (CUS) , 2018, DOI: 10.4236/cus.2018.63023
Abstract:
Based on the theory of “the image of the city” proposed by Kevin Lynch, the article will discuss the protection and renovation of historic districts from five aspects: road, boundary, nodes, landmarks and region. And in this article, we will analyse three historic districts: Nanluogu Alley in Beijing, Guangsheng Temple in Yixian, Dongguan Street in Dalian. The purpose of this discussion is to explore how to improve the status of historic district in the city.
Strain and Cracking Surveillance in Engineered Cementitious Composites by Piezoresistive Properties
Yu JiaHuan,Hou TsungChan
EURASIP Journal on Advances in Signal Processing , 2010,
Abstract: Engineered Cementitious Composites (ECCs) are novel cement-based ultraductile materials which is crack resistant and undergoes strain hardening when loaded in tension. In particular, the material is piezoresistive with changes in electrical resistance correlated with mechanical strain. The unique electrical properties of ECC render them a smart material capable of measuring strain and the evolution of structural damage. In this study, the conductivity of the material prior to loading was quantified. The piezoresistive property of ECC structural specimens are exploited to directly measure levels of cracking pattern and tensile strain. Changes in ECC electrical resistance are measured using a four-probe direct-current (DC) resistance test as specimens are monotonically loaded in tension. The change in piezoresistivity correlates the cracking and strain in the ECC matrix and results in a nonlinear change in the material conductivity.
The coupled Schodinger hierarchy associated with third-order algebraic curves and algebro-geometric solutions
Yu Hou,Engui Fan
Physics , 2012,
Abstract: By introducing Lenard recursion equations, we derive a general coupled nonlinear Sch$\mathrm{\ddot{o}}$dinger (CNLS) hierarchy associated with well-known Manakov system and Sasa-Satsuma system. Based on the characteristic polynomial of Lax matrix for CNLS hierarchy, we obtain a third order algebraic curve $\mathcal{K}_{m-2}$ of arithmetic genus $m-2$, from which we establish the associated Baker-Ahhiezer functions, meromorphic function and Dubrovin-type equations for analogs of Dirichlet and Neumann divisors. Using these results and the theory of algebraic curve, we obtain the explicit theta function representations of the Baker-Ahhiezer functions, the meromorphic function, and in particular, of the algebro-geometric solutions for the entire CNLS hierarchy.
Hydrodynamics of Normal Atomic Gases with Spin-orbit Coupling
Yanhua Hou,Zhenhua Yu
Physics , 2015,
Abstract: We derive the linearized hydrodynamic equations for the normal atomic gases of the spin-orbit coupling by the NIST scheme with zero detuning. We show that the hydrodynamics of the system crucially depends on the momentum susceptibilities which can be modified by the spin-orbit coupling. We reveal the effects of the spin-orbit coupling on the sound velocities and the dipole mode frequency of the gases by applying our formalism to the ideal Fermi gas. We also discuss the generalization of our results to other situations.
Algebro-geometric solutions for the two-component Hunter-Saxton hierarchy
Yu Hou,Engui Fan
Physics , 2014, DOI: 10.1007/s00033-013-0339-8
Abstract: This paper is dedicated to provide theta function representations of algebro-geometric solutions and related crucial quantities for the two-component Hunter-Saxton (HS2) hierarchy through studying an algebro-geometric initial value problem. Our main tools include the polynomial recursive formalism, the hyperelliptic curve with finite number of genus, the Baker-Akhiezer functions, the meromorphic function, the Dubrovin-type equations for auxiliary divisors, and the associated trace formulas. With the help of these tools, the explicit representations of the algebro-geometric solutions are obtained for the entire HS2 hierarchy.

The Fundamental Plane Relation of Early-Type Galaxies: Environmental Dependence
Lei Hou,Yu Wang
Physics , 2014, DOI: 10.1088/1674-4527/15/5/004
Abstract: Using a sample of 70,793 early-type galaxies from SDSS DR7, we study the environmental dependence of the fundamental plane relation. With the help of the galaxy group catalogue based on SDSS DR7, we calculate the fundamental planes in different dark matter halo mass bins for central and satellite galaxies respectively. We find the environmental dependence of the fundamental plane coefficients are similar in $g$, $r$, $i$ and $z$ bands. The environmental dependence for central and satellite galaxies is significantly different. While the fundamental plane coefficients of centrals vary systematically with the halo mass, those of satellites are similar in different halo mass bins. The discrepancy between centrals and satellites are significant in small halos, but negligible in the largest halo mass bins. These results remain the same when we only keep red galaxies, or galaxies with $b/a>0.6$, or galaxies in a specific radius range in the sample. After the correction of the sky background, results are still similar. We suggest that the different environmental effects of the halo mass on centrals and satellites may arise from the different quenching processes of them.
