Non-standard warehouse receipt pledge credit is a common and basic service form of supply chain financial products. This paper attempts to realize formalization and visualization description for such products. Petri net is used to model the business process of this service, and a hierarchical business model is built with the idea of modularization. Based on model correctness and performance analysis,...
The time-domain response is analyzed by precise integration method in condition of non-uniform coupled transmission lines in this paper. Different to the traditional method, this method directly analyzes it according to the non-uniformity of non-uniform transmission lines so as to avoid decoupling the coupled telegraph equations. The accuracy and speed of the analysis are improved greatly. It is a...
Sulfur dioxide SO2 is an important decomposition byproduct of sulfur hexafluoride SF6 under partial discharge in GIS apparatus. Responsive characteristics of semiconductor chemical gas sensors can be extremely improved by morphology tailoring of the sensing materials. In this manuscript, hierarchical flower-shaped ZnO sensing materials were synthesized with an environmental-friendly hydrothermal method...
Traditional classification algorithms addressing imbalanced-class dataset mostly concentrate on the majority classes' accuracy, such that the minority class's accuracy is usually ignored. Focusing on this issue, we propose a novel classification algorithm using Ensemble Feature Selections (EFS) for imbalanced-class dataset. This algorithm utilizes the superiority of EFS in accuracy, then considers...
Anisotropic transmission of ultrathin freestanding multi-walled carbon nanotubes (MWCNTs) film has been investigated using terahertz (THz) time-domain spectroscopy. The super-aligned MWCNTs films were fabricated by a novel method—drawing and winding carbon nanotubes on square-shaped polytetrafluoroethylene (PTFE) frame. The MWCNTs film exhibited anisotropic transmittance of THz wave depending on the...
The emerging new data types bring tremendous challenges to data mining. There is an enormous amount of high-dimensional class-imbalanced data in different fields. In this case, traditional classification methods are not appropriate because they are prone to ensure the accuracy of the majority class. Meanwhile, the curse of dimensionality makes situations more complicated. Finding a complicated classifier...
Traditional deterministic methods usually applied to the most severe and low probability events in power system risk assessment, computation results are therefore much conservative accordingly. Considering both probability and their impact of the effects, risk assessment methods can provide comprehensive effect on the whole power system. The status quo related to risk assessment is reviewed. The meaning...
According to the Signaling Theory, excellent auditors have excellent auditing quality. The quality of accounting information from a listed company that hired an excellent auditor for its IPO auditing is more secure, hence favored by investors. This paper uses data from Growth Enterprises Market (GEM) listed companies as a sample, and establish an OLS multiple linear regression model to analyze the...
Using the vacuum deposition method and the organic semiconductor copper phthalocyanine make of the structure of Au (Emitte) / CuPc / Al (Base) / CuPc / Au (Collector) the five-layer laminate structure organic transistor sensor. Specially appointed gases such as O2, NO2 will occur oxidation-reduction reduction when they were absorbed by the emitting region's organic thin film of organic transistor...
Zhang dynamics (ZD) and gradient dynamics (GD) are both powerful methods. Based on a pendulum system, this paper investigates both of the explicit and implicit tracking control using the ZD method. For solving the singularity-containing implicit tracking problems, this paper overcomes the singularities by using the ZD method in combination with the GD method (i.e., the ZG method). Analyses and simulations...
In Content Based Image Retrieval (CBIR) system, Relevance Feedback (RF) technique can substantially promote retrieval accuracy. As a popular algorithm of Relevance Feedback, Query movement was widely applied in this area and it moves the query in the input space towards relevant images. However, traditional Query Movement algorithm has significant disadvantages. It is to reduce the similarity between...
The sub-micrometer vertical type current channel of semi-conductive Al gate organic semiconductor copper phthalocyanine thin film transistor (VOTFT) with five layered structure of Au (Drain)/CuPc/Al(Gate)/CuPc/Au (Source) is fabricated by vacuum evaporation technique with organic semiconductor copper phthalocyanine (CuPc). As the thickness of semi-conductive Al thin film is approximately 20nm, the...

An empirical analysis is made, based on the capital allocation efficiency model of Jeffrey Wurgler, on the quantitative relationship between physical capital growth and profit growth of Chinese papermaking and paper products industry. The results show that the physical capital allocation of China papermaking and paper products industry is inefficient. Therefore the main factors which constrain physical...
Based on the perspective of industrial competitiveness, this paper systematically studied the resource base of Chinese timber industry. The concept and the categories of resources were firstly defined, followed by the meaning of resource base. The contribution of resources was then theoretically analyzed so that its theoretical basis has been expanded in view of competitiveness sustainability and...
How to screen active components of herbal drugs is still a hot topic of pharmacologists and pharmaceutical chemists. The main aim of the study was to establish a strategy to tract the active components in early stage based on the fact, that a compound (component) can not take systematic effect without binding to a biomolecule of organism. Affinity constants (KD or KD) and relative affinity indexes...
One novel Cu(II)-Fe(III) heteronuclear complex [Cu2(oxen)Fe(CN)5(NO)]n (H2oxen = N,N'-bis(2-aminoethyl)oxamide) was synthesized by the reaction of Cu(oxen)·2H2O with Cu(ClO4)2·6H2O and Na2[Fe(CN)5NO]·2H2O. The crystal structure was determined by single-crystal X-ray diffraction. The complex crystallizes orthorhombic with space group Pnma, and forms a centrosymmetric Cu(II)-Fe(III) heteronuclear molecule...
First of all, the paper discusses the theoretical relationship of financial ability and industrial development. It is suggested that the financial ability is the basic requirement of industrial development, and is the comprehensive reflection of industrial competitiveness. Second, the status quo of the financial ability of Chinese timber industry is analyzed in such respects as internal financing,...
Social channel is the main component of telecom operators' marketing channel. Channel loyalty has become an important issue of telecom operators' channel management, with especially significant research and practical value under the environment that competition increases and services homogenates seriously among three full-service telecom operators. In order to study the connotation of channel loyalty,...
