Live Virtual Machine (VM) consolidation is an effective method of improving energy-efficiency level in green data centers. Currently, to evaluate energy consumption in green data centers, energy-efficiency evaluation model with CPU utilization rate has been proposed. However, it is not suitable for data-intensive computing due to great energy consumption by GPU-intensive processing. In this paper, we have proposed a new energy evaluation model with CPU and GPU utilization rates. There are two kinds of policies in live VM consolidation: one for VM selection and the other for VM allocation. Some researchers have proposed their solutions based on VM selection policy or VM allocation policy respectively. However, it will be a better energy-efficiency VM consolidation policy if these two polices are integrated together. Based on these two policies, a fast Artificial Bee Colony (ABC) based energy-efficiency live VM consolidation policy with data-intensive energy model, named as DataABC, is proposed. DataABC adopts the idea of Artificial Bee Colony algorithm to get a fast and global optimized decision of VM consolidation. Compared with two state-of-art policies of PS-ABC and PS-ES, the total energy consumption of DataABC evidently drop by 9.72% and 5.84% respectively. As a result, based on the ESV metric, the DataABC approach has proved that (a) the energy-efficiency evaluation model with data-intensive computing is valid and that (b) DataABC can save energy with a good Quality of Service (QoS) in green data centers. © 2016 Elsevier B.V.

There are many thermal or biological methods for the utilization of biomass such as combustion, gasification, and pyrolysis. Gasification is a thermochemical conversion method that converts carbon-based fuels (solid and liquid) into a high-caloric-value syngas via partial oxidation. In this article, to investigate the influence of plant capacity on installed capital cost and stoichiometric ratio (SR) on gas composition and gas caloric value, an Aspen Plus model was developed where it was assumed that the reactions operate under steady-state conditions. With increasing SR from 0.2 to 0.8, the caloric value of the produced gas decreased sharply for both fuels due to a significant reduction in the concentration of H2, CO, and CH4. In addition, for higher plant capacities, the installed capital cost showed a constant rate, because it depends strongly on the individual capital costs of equipment and the capacity cost plays a minor role. © 2017 Taylor & Francis

Information technology outsourcing relationship is one of the key issues to IT outsourcing success. To explore how to manage and promote IT outsourcing relationship, it is necessary to understand its evolution process. Firstly, the types of IT outsourcing based on relationship quality and IT outsourcing project level will be analyzed; Secondly, two evolution process models of IT outsourcing relationship are proposed based on relationship quality and IT outsourcing project level, and the IT outsourcing relationship evolution process is indicated; Finally, an IT outsourcing relationship evolution process model is developed, and the development process of IT outsourcing relationship from low to high under the internal and external power is explained. © The Authors, published by EDP Sciences.

A lattice Boltzmann model for the Gross-Pitaevskii equation is proposed in this paper. Some numerical tests for one- and two-dimensional Gross-Pitaevskii equation have been conducted. The waves of the Gross-Pitaevskii equation are simulated. Numerical results show that the lattice Boltzmann method is an effective method for the wave of the Gross-Pitaevskii equation. © 2017 COSPAR.

Mobile learning is the latest development of online education, and mobile phones are regarded as the most promising mobile learning terminal equipment and the mobile learning resources for mobile phones have begun to emerge. Reasonable and effective interaction is very important in the learning process, especially the interaction between students and learning resources; however, the mobile terminal performance of different media formats, scripts, and interactive content, limited support, making the learning resource interactive activities designed to become the mobile phone successfully applied the key to mobile learning. In this paper, the practice of project development needs, from learning resource micro-content, learning content interaction and human-machine interface layout, multiple levels of design strategies and methods, and examples of mobile learning resource interaction design. © 2012 IEEE.

Finance and economics university practice teaching with teaching software platform based on network, the software platform to the large server to run the computer room environment, the server determines the success of practice teaching. Creep corrosion can lead to the production of lead-free process card function failure, cause the server can not operate normally. This paper analyzes on the creep corrosion the mechanism analysis, the conditions of. At the same time according to the proposed scheme, the high humidity and high sulfur environment of computer lab and practice prove, through the control room environment, to eliminate creep corrosion. © (2014) Trans Tech Publications, Switzerland.

In this paper, a new lattice Boltzmann model for the ion-acoustic solitary waves in plasma is proposed. By using the Chapman-Enskog expansion and the multi-scale time expansion, a series of partial differential equations in different time scales are obtained. By selecting the appropriate moments of the equilibrium distribution functions, the macroscopic equations are recovered. In numerical examples, we simulate the propagation of the ion-acoustic solitary waves. Numerical results show that the lattice Boltzmann method is an effective tool for the study of the ion-acoustic solitary waves in plasma. © 2015 COSPAR. Published by Elsevier Ltd.

Through statistical description and analysis of econometric models of energy consumption, environmental conditions, and their impact on economic development, we draw conclusions that present China's economic growth is at the cost of the huge energy consumption and environmental pollution. To maintain long-term sustainable economic development, and achieve intensive economic growth, it is necessary to take industrial ecology and green GDP accounting approach of management targets. © 2011 Published by Elsevier Ltd.
