A Study on Credit Appraisal System of C2C E-Commerce
—Based on the Analysis of Taobao

Jiangang Pang, Zhiying Liu
American Journal of Industrial and Business Management (AJIBM) , 2014, DOI: 10.4236/ajibm.2014.412078
Abstract: In the virtual network environment, the C2C e-commerce has some problems in product quality, service, credit speculation. At present the credit appraisal system offered by domestic C2C e-commerce website ensures the network security to a certain extent while it has some problems in identity verification, evaluation rules and model, credit of buyers and sellers and so on. Focused on the largest national C2C shopping website—Taobao, this article mainly analyzes the present situations and problems of the credit appraisal system, puts forward some improved suggestions of the real-name authentication, credit and transaction appraisal rules and so forth, and then establishes improved credit appraisal system.

Variance Window Based Car License Plate Localization  [PDF]
Jing Pang
Journal of Computer and Communications (JCC) , 2014, DOI: 10.4236/jcc.2014.29009

In this paper, a new method for discovering the candidate car license plate locations is presented. First, the image is decomposed using a Haar wavelet to get the HL band with vertical edges. Then, the HL band image is binarized using an Otsu threshold. Next a black top-hat algorithm is applied to reduce the effects of interfering large continuous features other than the license plate. At this time, a moving window based modified variance score calculation is made for areas with white pixels. This work found that the top 3 detected rectangle windows correctly locate the license plate regions with a success rate of about 98.2%. Moreover, the proposed method is robust enough to locate the plates in cases where the rough vehicle position has not been previously discovered and the cars are not centered in the image.

Research and Practice on the Cultivation of Engineering Competence for Software Talents in Universities  [PDF]
Xiyu Pang
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.32020
Abstract: This paper analyzes the phenomenon that companies are in need of talents, yet students have difficulty in finding jobs. It proposes new solutions for “Bridging the gap between university education and social demand and cultivating qualified talents for software companies”, that is, to cultivate the students’ competence for software engineering in curriculum design. Besides, it gives a scheme for cultivating the students’ competence for software engineering in curriculum design, and delivers good results in practice.
Short Report of a Preliminary Open Study of Synofit-Containing Bio-Curcumin, Greenlipped Mussel and Blackcurrant Leaf Extract in Arthritis  [PDF]
Jiangang Qu, Christian Mélot, Thierry Appelboom
Open Journal of Rheumatology and Autoimmune Diseases (OJRA) , 2015, DOI: 10.4236/ojra.2015.54018
Abstract: To evaluate the potential benefit of Synofit—an association of Curcumin, Perna canaliculus green-mussels and blackcurrant leaf extracts, a real life open study was performed among 86 adult out patients suffering from Fibromyalgia (n = 22), low back pain (n = 33) or knee osteoarthritis (n = 31) who accepted to take 3 tablets a day during 1 week then 2 capsules of Synofit during 2 months in addition to their conventional therapy (mainly analgesics and anti-inflammatory) and then to report their evaluation of this complementary treatment. Statistical analysis included paired t test and when possible Wilcoxon signed rank test. Accordingly, the intermediate analysis showed that already within 4 weeks of treatment, an improvement quoted as “light” was statistically reported in patients with low back pain and knee osteoarthritis but not among those with fibromyalgia on pain, physical condition, global assessment of a benefit, quality of life but not on joint stiffness (although joint stiffness considered for the whole group was statistically improved). The limited number of patients and time duration of the study and the absence of double blind controlled study do not allow concluding on the efficacy but these preliminary analyses obtained from an intermediate analysis are encouraging for further studies.
Registration of Brain MRI/PET Images Based on Adaptive Combination of Intensity and Gradient Field Mutual Information
Jiangang Liu,Jie Tian
International Journal of Biomedical Imaging , 2007, DOI: 10.1155/2007/93479
Abstract: Traditional mutual information (MI) function aligns two multimodality images with intensity information, lacking spatial information, so that it usually presents many local maxima that can lead to inaccurate registration. Our paper proposes an algorithm of adaptive combination of intensity and gradient field mutual information (ACMI). Gradient code maps (GCM) are constructed by coding gradient field information of corresponding original images. The gradient field MI, calculated from GCMs, can provide complementary properties to intensity MI. ACMI combines intensity MI and gradient field MI with a nonlinear weight function, which can automatically adjust the proportion between two types MI in combination to improve registration. Experimental results demonstrate that ACMI outperforms the traditional MI and it is much less sensitive to reduced resolution or overlap of images.

Structural determination and electronic properties of 4d perovskite SrPdO3
Jiangang He,Cesare Franchini
Physics , 2013, DOI: 10.1103/PhysRevB.89.045104
Abstract: The structure and ground state electronic structure of the recently synthesized SrPdO$_3$ perovskite [A. Galal {\em et al.}, J. Power Sources, {\bf 195}, 3806 (2010)] have been studied by means of screened hybrid functional and the GW approximation with the inclusion of electron-hole interaction within the test-charge/test-charge scheme. By conducting a structural search based on lattice dynamics and group theoretical method we identify the orthorhombic phase with $P_{nma}$ space group as the most stable crystal structure. The phase transition from the ideal cubic perovskite structure to the $P_{nma}$ one is explained in terms of the simultaneous stabilization of the antiferrodistortive phonon modes $R_4^+$ and $M_3^+$. Our results indicate that SrPdO$_3$ exhibits an insulating ground state, substantiated by a GW$_0$ gap of about 1.1 eV. Spin polarized calculations suggests that SrPdO$_3$ adopts a low spin state ($t_{2g}^{\uparrow\downarrow\uparrow\downarrow\uparrow\downarrow}e_g^0$), and is expected to exhibit spin excitations and spin state crossovers at finite temperature, analogous to the case of 3$d$ isoelectronic LaCoO$_3$. This would provide a new playground for the study of spin state transitions in 4$d$ oxides and new opportunity to design multifunctional materials based on 4$d$ $P_{nma}$ building block.
