School of Computer Science and Technologies University of Electronic Science and Technology Chengdu, Sichuan, P.R.China mtzhou@uestc.edu.cn Although green computing is becoming increasingly important in IT systems, it presents challenging problems to system designers. Designers need to take into account energy consumption during the phase of system design and to find solutions to reduce it. Green computing involves all aspects of IT systems, such as chips, system architectures, compilers, operating systems, communication networks and application services, and so on[1]. Further, these aspects are interdependent and complicated. As a result, building lowcost and low-power-consumption systems is a challenging and important activity. Such a new computing paradigm introduces new technical challenges to system designers. In light of today’s requirements for green computing, we present latest research efforts that attempt to deal with them and indicate still open issues. We thus discuss the connotation of green computing and sketch our view on the next generation of IT systems for green computing. We further identify key issues relevant to green computing and evaluate different approaches to these problems. The scope of this survey covers basic concept as well as techniques and methods in support of green computing. The remainder of this paper is organized as follows. In section 2, we introduce the connotation of green computing. In section 3, we look deeper into some key issues relevant to green computing and some real solutions are shown as well. Finally, section 4 points out...

I understand that failure to attribute material which is obtained from another source may be considered as plagiarism. (Signature of student) Abstract Cloud computing is a breakthrough innovation in information technology industry. It brings new efficiencies and advantages to business. There is much hype about environmental impacts of cloud computing on green issues. Some favour of cloud computing as solution to green issues while others blame cloud computing as burden to environmental problems. Cloud computing, nevertheless, like other technology, is neutral. It can be either cause or solution to environmental issues. There is growing pressure on cloud computing industry to reduce the environmental impacts of their data centres. The current trend focuses on developing green cloud computing. However, the evaluation of solutions to green cloud computing bases on certain standards, metrics and benchmarks, which assess only parts of the environmental issues with cloud computing. This report will concentrate on green issues with cloud computing. Significant positive and negative impacts of cloud computing on the environment issues will be investigated. Next, a classification of green issues with cloud computing......

...and Manufacturing resource planning (MRP II), being unable to keep pace with times, were no longer to be relevant because they were not quite useful for decision-making and control purposes in such a competitive environment. Without replacing these elements, Enterprise resource planning (ERP) came to represent “a larger scope that reflected the evolution of application integration beyond manufacturing” (Sheilds and Mureell, 2005). According to Anurag (2009), MRP evolved into ERP as managers noticed that ‘routings’ and capacity planning activity had become essential parts of the software architecture. ERP was firstly introduced by Gartner Group Inc in 1990s, generally defined as a process by which a company manages and integrates different parts or areas of its business, for instance, purchasing, inventory, sales, marketing, finance, human resources and so on. In this essay, we will firstly, illustrate the origin and development of ERP and then, investigate how and why it emerged and diffused in 1990s. After that, intended and unintended effects of ERP will be evaluated. Finally, the conclusion will be drawn and recommendation of future research will be given. The main objective of this essay is to learn ERP in all aspects and put efforts to evaluate it. In order to lower total costs in the entire supply chain, save throughput time, reduce inventory, provide better delivery and also satisfy customers, ERP became more inclusive to solve practical problems. By the mid-1990s,......

...Journals Full Length Research Paper Key issues relating to management information systems from the perspective of managers of Iran’s agricultural extension providers Abdolmotalleb Rezaei*, Ali Asadi and Ahmad Rezvanfar Department of Agricultural Extension and Education, University of Tehran, Karaj, Iran. Accepted 26 May, 2011 The purpose of the paper is to investigate issues relating to the management information systems of agricultural extension providers in Iran. A survey study was applied as a methodology of research work. Data were collected using a structured questionnaire that addressed evaluating managers’ responses with regard to management information system (MIS) key issues. All issues had mean score greater than five as perceived by managers. This would suggest that most key issues are moderately important in the present time. To delineate more clearly the relationships between the organizational factors and MIS key issues ratings, a descriptive model is currently under development. Future work is to formulate a research model that more precisely describes the relationship between the organization's factors and the MIS key issues rankings across the countries. The organization factors should extend factors covered in the present study to those that are broadly pertinent to the dimensions of the organization's operating environment. To identification of issues of agricultural extension management information system, and how the managers rate the......

...negatively impact the Federal Government’s ability to serve the American public. Cloud computing has the potential to play a major part in addressing these inefficiencies and improving government service delivery. Amtrak, one of top client for Lockheed Martin is facing similar challenges to reduce the cost of IT infrastructure maintenance in their data center operations. Lockheed Martin has a unique cloud model which is focused on providing solutions as a service based on a mission focused approach to secure cloud delivery. They have successfully implemented cloud services for many clients. This study specifically focused on implementing the cloud computing strategy and services provided by Lockheed Martin that can significantly help Amtrak to provide highly reliable, innovative services in an efficient manner and at the same time reduce IT operating costs. Interviews were conducted with key business stakeholders at Amtrak and also with some of the IT project team members to learn about the existing data center model set up, data storage, and the hardware and software applications that are currently used. Interviews were also conducted with employees to understand the perception of cloud system infrastructure services and how it can help them. This report concludes that Lockheed Martin is deeply involved in delivery of cloud computing services to his clients and will provide a unique cloud computing framework that can benefit Amtrak. The challenge at Amtrak is that even......

Cloud Computing

...CLOUD COMPUTING: PAST, PRESENT, AND FUTURE John P. Sahlin (sahlinj@gwu.edu) The George Washington University, United States of America ABSTRACT Defining cloud computing can be difficult, as each organization often has its own spin on the definition. Despite being hard to define, Gartner Research named cloud computing as one of the top technologies to watch in 2010, 2011, and 2012. At its core, cloud computing is a technical architecture that meets a specific business need. This chapter traces the roots of cloud computing from its origins in mainframe distributed computing, discusses the basics of the cloud computing model today, and offers insights for future directions that are likely to be pursued in the cloud computing arena. A number of challenges to cloud computing are identified, including concerns of security and how to deal with the rise of mobile computing. The chapter ends with recommendations on how to choose which cloud model is most appropriate to meet your organization’s needs and how to establish a successful cloud strategy. INTRODUCTION: DEFINING THE CLOUD I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description; and perhaps I could never succeed in intelligibly doing so. But I know it when I see it. ~ Hon. Potter Stewart (U.S. Supreme Court Justice) Why did Gartner Research place cloud computing at the top of the list of most important technology focus areas for the past three......
