Financial statement fraud has been one of the biggest challenges in the modern business world. Financial accounting fraud detection (FAFD) has become an emerging topic of great importance for academic, research and industries. In this paper, the effectiveness of Data Mining (DM) classification techniques in detecting firms that issue fraudulent financial statements (FFS) and deals with the identification of factors associated to FFS are explored. Our study investigates the usefulness of Data Mining techniques including Decision Trees, Neural Networks and Bayesian Belief Networks in the identification of fraudulent financial statements. At last, we compare the three models in terms of their performances. Copyright © 2017 American Scientific Publishers.

By Means of Fluent 6.3, the paper simulated the solid-liquid two-phase flow to a centrifugal sewerage pump, using Eulerian Mixture Model under different working condition and different particle size. The simulation draws some conclusion on distributive rules of solid particle inside impeller passage. The results for this simulation were as following: Distributive rules of solid particle inside impeller passage mainly relate to particle size. Meanwhile, the volume fraction of particles and operation condition have influence on distributive rules of solid particle. The simulated results can explain commendably that attrition took place inside pump passage when pump transported solid-liquid two-phase flow. Meanwhile, the simulated results have reference price to improve the design for pump and performance of pump. © (2011) Trans Tech Publications.

computer network has been developing rapidly and LAN, Campus Network and Internet have applied in educating, providing a personalized teaching environment. In this thesis, BBS, SQL and Serv-U FTP are integrated to build an autonomous learning and discussing platform featuring teacher-student interaction and resources sharing. The design of teaching, audience of teaching, environment, and methods, etc are discussed in detail and steps of LAN-based education are introduced. This thesis has assessed the effectiveness of LAN-based education from results of students' academic examination and final oral examination and the results have proved that LAN-aided English teaching platform has reached expected aims.

Associative memory is a highly effective mnemonics, hence it was soon applied by vocabulary learning software. This paper examines the design and application of an English vocabulary learning computer system based on associative memory (AM-ELS). This system uses Sybase's latest database model designer CASE toolkit named Sybase Power Designer 12.0, and creates 7 data tables including user registration table (Flog. dbf), useful sample sentence table (Enms-dt0.dbf), English vocabulary table (Wpmsdt0.dbf), memory test results table (Wpmsdtsc. dbf), table of wrong words in memory tests (Wpmsdtrr. dbf), memory test score table (Wpmsdtsc. dbf 7), and option data table (Wpmsdtva. dbf). AM-ELS is a multi-user, practical, easy to learn, visualized and object-oriented computer-aided learning system developed under VFP9.0. Experiments show that this system can improve users' associative capacity and foster their ability to use associative memory to consolidate memory.

In this paper, vibration information of rolling bearings under 5 working conditions, including normal bearings, bearings with wear and tear on the outer circle or running pulley and so on, are collected. Obtained the relationships between parameters of service life of bearings and changes of time, such as the amplitude range, the frequency domain, and the energy around wavelet packets. Summarized a more detailed regular pattern for bearings' wear and tear. © (2014) Trans Tech Publications, Switzerland.

The non-state-owned economy makes great progress since Chinese reform. The non-state-owned economy takes more and more proportion in the whole country economy. The quality of the development of non-state-owned economy affects the whole economy operation directly. The sizes of private enterprises are small in the whole. But scandal of some large private enterprises appeared continually. Many scholars appeal that the private enterprises are treated unfairly by local governments and they should get more attention. The second question is whether the distance between the government and the private enterprises is close or not and how the government should treat private enterprises. And the two questions will be discussed in the paper. © 2014 WIT Press.

This paper introduces a new fuzzy active disturbance rejection control (ADRC) design technique into permanent magnet synchronous motor (PMSM) speed regulation system. By using fuzzy logic control, the proportional coefficient of nonlinear state error feedback (NLSEF) is timely adjusted to obtain the suitable feedforward control variable. The uncertain term of PMSM is tracked and estimated by using the extended state observer (ESO). The control variable can be obtained through subtracting the estimator of ESO from the output of NLSEF. The simulation results show that the controller operates robustly under modeling uncertainty and external disturbance and produces better dynamic performance than the ADRC controller. © (2011) Trans Tech Publications.

We have searched for free software tools that help in some tasks of the electronic design flow. Then, we have performed a rapid check and test of the programs in order to select which ones are worth continuing working with. We have found that about 39% of the projects are abandoned. On the positive side, we have found that there are several programs that cover each of the tasks considered in this study: analog simulation, digital simulation, schematic capture, PCB design, and HDL design. Thus, we think that efforts should focus on improving existing projects, rather than on creating new ones, unless new projects include original approaches. © 2014 WIT Press.
