This study explores the application of artificial intelligence on the causal relationship between mining production index and electricity load. The data used is the total mining production index and total electricity consumption in the mining sector sampled on a monthly basis from January 1985 to December 2011 in South Africa. Optimally-pruned and basic extreme learning machines were used to develop...
In this paper, we address the issue of speech polarity detection using strength of impulse-like excitation around epoch. The correct detection of speech polarity is a crucial step for many speech processing algorithms to extract suitable information. Occurrence of errors in the detection of speech polarity could have an impact on the performance of speech systems. Automatic detection of speech polarity...
Due to increasing energy costs and the demand to lower CO2 emissions in the production, companies try to apply energy efficient technologies in green (new installations) and brown (modernized installation) production systems. Hence, the procedures of energy efficiency assessment have to be integrated with production systems on the machine control level. Presented work compares the energy efficiency...
SCOPE is adopted by thousands of developers from tens of different product teams in Microsoft Bing for daily web-scale data processing, including index building, search ranking, and advertisement display. A SCOPE job is composed of declarative SQL-like queries and imperative C# user-defined functions (UDFs), which are executed in pipeline by thousands of machines. There are tens of thousands of SCOPE...
On the basis of summarizing the definition of modern service industry from many scholars, this paper proposes the author's understanding of modern service industry and establishes evaluation index system of modern service industry in China. By using factor analysis in multivariate statistical method, the development level of modern service industry in 31 provinces of China is analyzed, revealing the...
Safety input is a way of safeguarding mining, as well as one of main reasons for the increased growth rates of Total Factor Productivity (TFP). To figure out the contribution of the safety input to mining economic growth, a new production safety index system with six principal items describing China mining safety was constructed. The study found that China mining production safety level was improved...
Modern mine production has brought unprecedented demands on the safety, high yield, and high efficiency, which means to realize the integration management control of decision making, production process management, and process control on the basis of the production mode on spot adopts automation equipment. The aim of establishing integrated management control information system of mine production and...
Integrating the principal components analysis with R analysis software, the article offers a solution to synthetically evaluate coal mining enterprises' economic benefits. The method can not only reflect different factors in coal's economic benefits, but also determine the degree of importance of these factors, thus saving the trouble of importance assessment by decision-makers when faced with multiple...
Evaluation for the trustworthy of software is now one of the focuses of software engineering. This paper establishes a workflow software trustworthy evaluation model based on grey relation by defining the evaluation indexes of workflow software' capability using the fuzzy math method, and explains the specific calculation process taking the current workflow productions as examples. According to the...
In the research field of corporate entrepreneurship (CE) and internationalization, the research of multinational subsidiary's entrepreneurial orientation (EO) is a new emerging topic. Although scholars have known importance of subsidiary's EO, but correlative theoretical and empirical research was scarce. There aren't still special conception design and dimension partition about multinational subsidiary's...
Hunan is a major agricultural province in China. This paper analyses the international competitiveness of Hunan agriculture from three levels. Firstly, we evaluate its competitiveness in achievement by using indexes of MS, RCA and TC, and find Hunan agriculture has certain advantage, but it shows a downward tendency. Next, Hunan agricultural competitiveness in strength is analyzed from price and quality,...
Intra-industry trade has become a main trade form in recent years. This paper focused on the empirical work on the determinants of intra-industry trade in Chinese manufacturing. We studied the determinants of intra-industry trade in Chinese manufacturing by considering the country characteristics and industry characteristics synchronously. Based on the regression analysis, we found that the level...
Residue burning is a quick, labor-saving practice to remove residue that is viewed as a nuisance by producers in most southern provinces of Iran. However, residue burning has several adverse environmental and ecological impacts. The burning of dead plant material adds a considerable amount of CO2 and particulate matter to the atmosphere and can reduce the return of much needed C and other nutrients...
The evaluation for current situation of ecological compensation is significant to strengthen the system of ecological compensation. In the study, the method based on the combination of analytic hierarchy process (AHP) and fuzzy theory is proposed to evaluate ecological compensation. Firstly, evaluation indexes for ecological compensation are described, and the evaluation model of ecological compensation...
Modern enterprise manages indexes more refined and systematically. This paper reviews common construction and function of data warehouse on huge iron & steel enterprise and gives an example of enterprise's index. This example explains the process of building subject data set and computing and analyzing indexes by models and methods in data warehouse platform. It is proved that using the results...
Modular product evaluation is one of key technologies in modular design. Three kinds of evaluation methods, which based on three modular design styles, were proposed in this paper. These methods integrated customer satisfaction index (CSI), product customization index (PCI) or modularity degree index (MDI). Then several modularization customized products can be evaluated. Some customer satisfaction...
Resource integration is the principal source of competitiveness for the mid-small enterprises cluster and enterprises. In order to evaluate resource integration capability of mid-small enterprises cluster, the meaning of resource integration capability of mid-small enterprises cluster is presented from the two levels of strategic thinking and tactical choice in this paper, and the evaluation index...
By applying of system theory and DEA, the coordinated development degree evaluation model of Chinese resources, economy and society was built up. The statistics data from 1997 to 2006 was adopted and the empirical study on the coordinated development condition was conducted. The result shows that the development presents two fluctuation stages in the recent ten years. In the first four years, it had...
R&D has been a principal source of the competitiveness of an enterprise. Cost management is the important guarantee for enterprises to get an upper hand in competition. The application of strategic cost management (SCM) in the R&D of an enterprise can help to cut its cost and enhance its competitive advantage. The paper analyzed the current cost management status of R&D in China, and put...
