This paper proposes a virtual resource (VR) allocation scheme for OFDMA based wireless virtualization networks (WVNs). The scheme considers the time-variant wireless channel quality from the technical perspective, as well as the network benefits for WVN elements, e.g., subscriber user equipments (SUEs), mobile network operators (MNOs) and wireless service providers (WSPs), from the economic perspective...
This paper discusses how to use the ArcEngine components and Orcale database to quickly draw the Yunnan Province digital isoseisms. Besides the current general ellipse model, the paper was the first time to complete the line source model of isoseisms drawing. At the same time, it improved the Binary search algorithm in order to quickly find closest active fault. Then the existing isoseisms file provided...
Service has for a long time been viewed as an interactive process during which the customer and service provider co-produce a service. Viewing citizens as co-producers of public service has also been accepted in some literatures. Although coproduction in business service and in public service has different features, the fundamental issues are almost the same when implementing the concept respectively...
Proceed from economy theory, this paper selects the best treatment method of slopes based on minimum investment principle. In economic analysis, the most important one is to find failure probability of slopes. Traditional calculation method doesn't consider the fuzziness of mechanical parameters. However, the fuzziness exists objectively. In this paper, fuzzy technique is introduced and failure probability...
Land is one of the important resources and material ensure mend for human being to survive and develop. The land resource is a fundamental element in the complex system of “population-resource-environment-development (PRED)”. By using ABM technology, based on Repast platform, establishes the decision-making model of the changes of land use type and classifies as three types of individual, company...
Granger causality is one of the most popular measures to reveal causality influence of time series and has been widely applied in economics and neuroscience due to its simplicity and easy implementation. In this paper, we first introduce two key assumptions which are showed to be pre-required for defining Granger causality; that is, without the two assumptions, one cannot draw a conclusion that there...
Circular economy is the main direction of the development of world economy, and now it is the economy developing pattern of our country. This paper describes the operation of green supply chain, and re-assesses the risk system of green supply chain, and then use Fuzzy-AHP comprehensive evaluation model to make an assessment for the Green Supply Chain Risk to provide a reliable basis and assurance...
An adaptive weighting divisia index method is applied to analyze the structure and efficiency quotient mix in affecting Chinese energy intensity through rearranging and reanalyzing the past 30 years' data. Based on the analysis, this paper concludes that the changes in China's energy intensity in the previous phase are mainly caused by efficiency factors, and by estimation it shall be affected by...
Based on the basic analysis of China's newest coal consumption data, the theory of co-integration is used in this article to analyze the co-integrate relationship between coal consumption and economic growth and the Granger causality model of coal consumption and economic growth is established, leading to the conclusion that there is no longer long-term co-integrate relationship between coal consumption...
In the open-end production system, production service of high-quality should be the product of effective interaction involved by multi-parties. Yet in fact there is critical asymmetric information between all the parities, the service providers and customers in particular. By applying the game theory and relevant knowledge in Information Economics, this paper builds a game model between service providers...
This paper uses the multiple regression analysis and the structural equation modeling (SEM) to study the relationship between venture capital and supporting environment. The empirical analysis results show that, the corporation leading science technology environment (CLSTE) and the government supportive policies synthesis level (GSPSL) have direct effects on the development of VC; the development...
