Ore recovery depends on the stope structure parameters, at the same time, stope safety will be changed according to difference stope structure parameters. A mechanics model of stope structure of room and pillar mining method is established with FLAC3D, a finite difference software, in this paper. And the stope stability changing with crustal stress and stope structure parameters is simulated. The...
According to some shortcomings of armored equipment maintenance, such as 'surplus maintenance' and 'corrective maintenance', Prognostics and Health Management (PHM) technology which was brought forward by USA army was introduced. Aiming at an armored vehicle engine, augmented-Failure Mode and Effect Analysis(aFMEA) was proceeded. Analysis on failure symptoms and sensor installation was introduced...
Organizing wireless sensor networks into clusters enables the efficient utilization of the limited energy resources of the deployed sensor nodes. Oftentimes the network is organized into clusters of equal size, but such equal clustering results in an unequal load on the cluster head nodes. Instead, we propose an Unequal Clustering Method (UCM) for network organization, which can lead to more uniform...
Apparel is rapidly becoming one of the most important sector in e-commerce sales. Yet, apart from a few more or less successful endeavors businesses are basically applying the in situ sales model to distance sales. In this paper, we demonstrate why this "cut and paste" approach does not work and how the computer/software industry may develop on existing technologies (3D Body Scanning, RFID...
The future trend of knowledge management will reflect how knowledge is produced and integrated in human social systems. The objective of knowledge management is to enhance knowledge processing. Expertise or expert knowledge is a vital resource of which decision makers need to become much more aware. This paper synthesizes the evolution of research on expertise from an interdisciplinary perspective...
D-index can be constructed from cross section data set and time series. Based on the basic constructing method, the paper also considered the D-index from panel data. The example is the west of Liaoning province and it also can be introduced around the northeast of China. Drought is one of the frequent natural calamities in China and it led an amount of loss. The paper gave the basic method from cross...
In this paper, we extend the martingale analysis of no-arbitrage pricing with transaction costs, bid-ask spreads and taxes. We establish the equivalence of a no-arbitrage condition for the existence of different shadow prices of certain optimal problems and obtain a characterization of state prices based on the absence of arbitrage.
Green procurement for forest product was a new topic in the field of global forest protection, implemented in some developed countries. The definition of green procurement for forest product and the connotations of legality and sustainability were analyzed in the paper, as well as its operation in practice. It concluded that green procurement of forest product provided a new idea to address the issue...
In order to evaluate listed companies' comprehensive performance and formulate investment strategy, this paper establishes evaluation index system of listed companies' comprehensive performance according to the combining principle of scientific characteristic and rational characteristic, objective characteristic and advisable characteristic. Meanwhile by using factor analysis method the paper establishes...
The objective of this study was to empirically examine the moderating effects of gender and organizational level (OL) on work stress-job demands (JD) and interpersonal conflict (IC), and job satisfaction (JS) for Chinese hotel employees. Data were collected from employees (n=271) in six upscale hotels of Zhejiang Province, China via self-administered questionnaire and then processed utilizing SPSS...
In mainstream software development there can often be a gap which exists between the stages of performing the architectural design of a software system and implementing the detailed algorithms and processes required in the program code. Code Rocket is a code visualization and documentation system which has been developed to fill this gap. Code Rocket provides automated design and documentation support...
A novel evaluating method is introduced in this research to better illustrate urban-rural land issues and accompanying connections with other subsystems in Beijing. Coordination degree is the key role in processing the evaluation, integrating a variety of indicators selected based on different subsystem orientation, including economic subsystem, social subsystem and environmental subsystem. The results...
The intention to build up Chinese Growth Enterprise Markets is to provide financing channel for small and medium-sized enterprises, thereby promote the small and medium enterprises to grow up and build up multi-level capital market system. To understand the financial condition of the listed companies on GEM, it makes analysis on asset-liability ratio, financial expenses and return on net assets and...
As more and more databases are published on the internet nowadays, it is increasingly important to maintain the security of published databases. In this paper, we propose a distortion-free scheme for embedding and verifying integrity information for relational databases. The proposed scheme does not require any additional storage to store the integrity verification information, nor does it introduce...
PTN is a new generation of connection -oriented technology, it not only can run the carrier-class Ethernet services, and also can concord with the traditional TDM service well. In this paper, based on mature, stable SDH devices management, network topology management, and process management, we design a new PTN network management module, in which we rebuild and update some database model and logic...
Emergency communication has been intensively investigated for solving suddenly-occurred events of public safety. Wireless network can play an important role of information acquisition and command decision-making in disaster areas, so a new Wireless Emergency Communication (WEC) algorithm is proposed in this paper. This algorithm possesses the characteristics of quick, stability, low energy and high...
The emergence of the internet, multimedia, collaborative software environments and group support systems has created new opportunities for organizations to form global virtual teams (GVTs) to work on complex virtual projects, and remain competitive. This development in information and communication technology over the last decade and a half has added a new dimension to management and has sparked a...
The improved grey correlative model was put forward in order to improve the objectivity of grey synthetic evaluation method. Balanced degree was ascertained by entropy theory. Weighted grey correlative degree was synthesized by grey correlative coefficient and entropy weights. Balanced adjacent degree, which was derived from weighted grey correlative degree and balanced degree, was taken as the evaluation...
Model Net is a graphical model used to represent and analyze the static structure of the model bases. Compared to other models, model composition method based on model net can not only greatly improve the efficiency of model composition, but also find out all the potential composite models for a given decision problem. However, the model net simplification and model composition algorithms may work...
Through the analysis on the life properties of building energy-conversation, this paper explains the coupling between nodes and the rule of cohesion within nodes in the lifecycle of building energy conservation. The energy-saving chain of construction engineering is combined with the coupling concept of synergetics. With the influence degree of coupling factors between upstream and downstream of energy-saving...
