Abstract: In this paper, an open-loop frequency domain analysis based on system identification is introduced. Using model identification tools in Matlab, the open-loop frequency domain characteristic could be derived accurately with the open-loop step response. Then, the closed-loop regulator could be designed with the open-loop frequency domain characteristic to fulfill the steady and dynamic requirements. This method is suitable for most of the systems. An example of Buck converter is proposed to represent the analysis process. Simulation model is built in Matlab software, and some factors which affect the precision of model identification and frequency domain analysis are taken into consideration. Finally, both open- and closed-loop experimental results verify the feasibility of the proposed scheme.

Abstract: In this paper we employ a two-stage approach to solve the project reviewer assignment problem. The objective is to best satisfy the preferences of reviewers. In addition, the number of total movement times of reviewers is minimized. Reviewers are first invited to show their preferences to the projects with a number to indicate their priority. After aggregating the data, a two-stage approach is used to best match the reviewers and projects. At the first stage reviewers are assigned, while at the second stage review venues are arranged in a way that the total change times of venues for reviewers are minimized. The results show that the proposed two-stage scheme is very helpful in solving the project reviewer assignment problem.

Abstract: During the past decade, criterion system of impairment of Assets has experienced a process from scratch and scattered to highly-developed in China. So far, “Accounting Standards for Enterprises No. eighth -- Asset Impairment ” has been implemented for nearly five years, and listed companies had compiled interim and annual reports during the 2007-2011 period which experienced a good condition overall. It is a significant breakthrough in the processing of accounting standards and accounting system, which constructs and consummates the system of asset impairment standard, require enterprises to reflect the value of the asset fairly and prevent inflated profits from property price foam. Introduction In recent years, the International and the domestic practice indicates that, in order to reflect the true value of the assets reliably, so as to improve the quality of accounting information, and reduce the uncertainty in decision-making, relevant accounting standards for recognition, measurement and presentation about asset impairment must be developed and implemented. During the past decade, criterion system of impairment of Assets experiences a process from scratch and scattered to highly-developed. In February 15, 2006, Ministry of Finance of the People’s Republic of China issued the "Accounting Standards for Enterprises No. eighth -- Asset Impairment" (Ministry of finance, PRC, 2006a), which regarding as the complete establishment of Chinese asset impairment standard system. Based on the experience of formulation and implement the accounting system and accounting standards, the Ministry of Finance drew some lessons from international accounting standards, and adopted the mode of “basic standard of impairment of Asset commanding other relative individual specific standards” to build asset impairment standard system, which has strong international significance.

Abstract: Many data cleansing algorithms are based on the low dimensional data currently, and can't meet the requirement of accuracy that data warehouse in the enterprise processes the high dimensional data. In this paper the idea of using the CLIQUE algorithm to process the high dimensional data was adopted. Aiming at the insufficient processing precision of this algorithm, the meshing and pruning algorithm were improved by using the dynamic incremental algorithms. The result of testing data shows that this algorithm can improve the accuracy of the clustering result and can effectively judge the similar clustering and abnormal points which support the high dimensional data cleansing.

Abstract: Radio Frequency Identification (RFID) is a new generation of Auto Identification and Data collection technology which helps to automate management processes and allows identification of large number of tagged objects like weapons, using radio waves. In this paper, we propose a novel RFID based management system: RFID based Weapons Management System (RWMS) since weapons management plays an important role in the military control. Since its reliability and flexibility, RFID technique has shown big advantages than the conventional management systems. Time saving, fast accessing of weapons, eliminating manual errors and high accuracy are the main benefits of the RFID based Weapons Management. RFID based Weapons Management system would allow fast transaction flow for the army and will prove immediate and long term benefits to army in traceability and security.

Abstract: This paper presents a method that can achieve the centralized management, unified monitoring and interactivity throughout the network for monitoring equipments of different manufacturers. This method achieves the automatic detection and extraction of different monitoring equipments communication protocols by capturing and analyzing the network packet. And it also achieves dynamic self-adaptive adjustment of resolution and flow-speed of audio and video data by dynamic analysis. The design implements a software system of distributed heterogeneous network and remote video surveillance, and achieves remote centralized management of video surveillance equipment which not provides compatible development kits.

Abstract: In order to reveal the incentive functions of BPR and ERP strategies for enterprise performance, the structure equation modeling (SEM) is used in this paper. By theoretical analysis, research hypothesis, model deduction, and model verification, the SEM can effectively reveal the correlation between BPR strategy and ERP performance in Chinese coal enterprises. For illustration, the collected copies are 313 enterprises, in which 278 copies are valid. Ratio of sample size and the number of outcome measures is about 7:1, which meets the basic requirements of SEM. The minimum value of 5 latent variables Cronbach Alpha is 0.778 and the results have higher reliability. The empirical results show that research model fitting effect is well so that it’s no need to continue model updating. The empirical research has revealed ERP-related microcosmic mechanism in the process of BPR implementation in Chinese coal enterprises, which can provide the effective theoretical references and support for enterprises to further promote ERP performance and raise management efficiency of Chinese coal enterprises.

Abstract: The variety of vacuum carburizing with prenitriding (PreNitLPC® technology) consists in metering ammonia in the stage of charge heating for carburizing to reduce grain growth in the surface layer of carburized steel. This paper presents the effect of nitrogen interaction on the reduction of austenite grain growth during vacuum carburizing and on the mechanical properties (fatigue strength, impact resistance) of the layer treated in this way in relation to conventional carburizing methods.

Abstract: In this paper, we have constructed supply chain consigning collaborative innovation modes and explored the innovation game process involving supplier, manufacturer and third-party research firm where the manufacturer acting as a core firm. We consider innovation cost coefficient information symmetry and asymmetry. The research shows that supplier’s innovation effect is more direct to supply chain. When innovation ability is similar, no matter judging from innovation inputs, expect profits or demand quantities, the mode of the supplier consigning innovation is superior to that with third-party and non-collaborative innovation.

Abstract: The paper focuses on the special manipulation effect of managerial discretion on CEO pay considering the moderating role of monitoring intensity in China. The paper empirically indicates that the manipulation effect of managerial discretion on CEO pay does exist, and quantitatively describes the degree of the manipulation effect, which shows that the manipulation effect of managerial discretion on CEO pay significantly decreases. The results prove that monitoring intensity can restrain the manipulation effect of managerial discretion on CEO pay. Only under a certain monitoring intensity, will CEO pay not exceed the reasonable level too heavily.
