Stereo Video Transmission Using LDPC Code  [PDF]
Rui GUO, Lixin WANG, Xiaoxia JIANG
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2008, DOI: 10.4236/ijcns.2008.13031
Abstract: Stereo video is widely used because it can provide depth information. However, it is difficult to store and transmit stereo video due to the huge data amount. So, high efficient channel encoding algorithm and proper transmission strategy is needed to deal with the video transmission over limited bandwidth channel. In this paper, unequal error protection (UEP) based on low density parity check (LDPC) code was used to transmit stereo video over wireless channel with limited bandwidth. Different correction level LDPC code was used according to the importance of video stream to reconstruction at the receiver. Simulation result shows that the proposed transmission scheme increases the PSNR of reconstructed image, and improves the subjective effect.
Experiment of New Additives Effect on Gas Hydrate Formation  [PDF]
Yuan Dai, Xiaoxia Zhong, Xin Jiang, Shuli Wang
Energy and Power Engineering (EPE) , 2014, DOI: 10.4236/epe.2014.66013
Abstract:

Natural gas hydrate has tremendous gas storage capacity; natural gas hydrate can be used to store and transport energy. The current problem faced is how to improve the hydrate formation rate and storage capacity, and form continuously. Compared to the pure water and SDBS solution, the ionic solution [HMIPS]OTs made by the team was the excellent additive and ensured the best reaction concentration range. Specific effects of different additives on hydrate formation were summarized; hydrate formation mechanism of additives was expounded. Considering the investment cost, operation cost, simple and stable operation of different surfactants, it is thought that the study of different additives mechanisms and developing the new efficient additive have the important value.

材料科学技术学报 , 1997,
Abstract: With the chemical synthesis of zinc oxythiomolybdate (ZnMoO2S2), its characters were studied by thermal analysis and X-ray diffraction method. The tribological properties of ZnMoO2S2were studied by high-temperature pin on disc tester, the results show that ZnMoO2S2 has good lubricating property from room temperature to 700℃, especially from 100℃ to 300℃, the friction coefficient is about 0.1.
CORRELATION BETWEEN STRUCTURE OF ELECTROCHEMICALLY DEPOSITED (Fe,Co,Ni)-P LAYERS AND PROCESS CONDITIONS

JIANG Xiaoxia,ZHANG Xuan,LIN Shuzhi,

金属学报 , 1986,
Abstract: A study has been made of the structure of the electrochemically deposited amorphous (Fe, Co, Ni)-P layers with relation to the process conditions, e.g. pH value, current density, metallic salt concentration, etc., by means of X-ray analysis, SEM and EPMA. Results showed that the effect of the process on the structure is realized by changing the P content of the layer. While P contained over 8%, below 3% or between 3 and 8%, a layer may be constructed as amorphous alloy, supersaturated solution or mixed structures respectively. The major factors affecting the structure of the deposited layer are found to be the concentration of NaH_2PO_2 and pH value of the bath. The structure of the layer may be also influenced by the potential of electro-deposition. The Fe-P, Co-P or Ni-P system is similar in amorphous structure of which the highest thickness of stack of the atomic face is 2.0, 2.5 or 6.5nm respectively.

Abstract:

Objective: We explored the relationship between traditional Chinese constitution and risk factors for cardiovascular disease in subjects with high-normal blood pressure (BP). Methods: The traditional Chinese constitution of 80 subjects with high-normal BP was judged by questionnaires and interviews. Measurements of cardiovascular and metabolic health in- cluded BP, body weight, body mass index (BMI), low-density lipoprotein cholesterol (LDL-C), 2-hour oral glucose tolerance test (OGTT2h), and waist cir- cumference. Statistical relationships between cardiovascular disease risk factors and specific Chinese constitution were evaluated by univariate and multivariate analyses. Results: Ping He, Tan Shi, and Yin Xu were the dominant constitutions in subjects with high-normal blood pressure. There were significant differences in weight, LDL-C, BMI, OGTT2h, and waist circumference between Tan Shi and Ping He (P < 0.01), in SBP and OGTT2h between Yin Xu and Ping He (P < 0.05), and weight, BMI, waist circumference, SBP, and LDL-C between Tan Shi and Yin Xu constitutions (P < 0.01). Logistic regression found a strong association between the Tan Shi constitution and LDL-C in subjects with high-normal blood pressure. Conclusion: Ping He, Tan Shi, and Yin Xu are the principle traditional Chinese constitutions in subject with high-normal blood pressure. The Tan Shi constitution is associated with multiple risk factors for cardiovascular disease (LDL-C, BMI, body weight, and waist circumference), while OGTT2h is closely related to the Yin Xu constitution.

A Research on the Evolution of Politic-Business Network, Relational Embedded and Family Enterprise Value: Regarding SAMSUNG Group as Example  [PDF]
Xiaoxia Huang
Open Journal of Business and Management (OJBM) , 2016, DOI: 10.4236/ojbm.2016.44069
Abstract: Globally, it is very common that many companies are keen to embed in the center of political-business (abbreviations with P-B) network [1]. The influence of government on enterprise is greatly important for it controls a large numbers of scarce and key resources and holds the power of approval on market access’s qualification and making regulations [2]. Then can close political-business network always bring positive benefits for enterprises value? Based on this, the paper takes the typicality and representative of cases as the standard and selects the case of SUMSANG to analyze the evolution relationship between P-B network, relational embedded and family business value. This paper puts forward that it is unreasonable to illustrate the positive correlation or negative correlation between them. The relationship between politics and business network is not simple or static, but is dynamic and nonlinear. The value of the enterprise is constantly changing with the degree of embedding in P-B network. There is a reasonable embedded threshold. Before reaching the “embedding threshold”, the value is increasing with the deepening of embedding degree; after the “embedding threshold”, the value is decreasing with the deepening of embedding degree. This is “inverted U” model of Uzzi [3].

Packing Densities and Glass Forming Ability of Alloys
Qing JIANG,Xiaoya XU,Hongjun NIU,Xiaoxia LU,

材料科学技术学报 , 1996,
Abstract: The random closed packing fraction of hard balls of three different sizes were measured by use of the Archimedes method. This packing fraction increases as the kind of balls with different sizes increases. The packing fraction is related to the mixing entropy of an ideal solution in respect to the holes among the hard balls. The composition zone of La-Al-Ni amorphous alloy made by cooling the alloy melt with a cooling rate of 90 Ks-1 is located at same zone of the largest values of packing fraction and mixing entropy of hard balls in the ternary system. where the proportion of atom sizes of La, Al and Ni is similar to that of hard balls. The packing fraction and the mixing entropy are qualitatively considered as one of the criteria of the glass forming ability of alloys
