introduction
Dear friends
We are trying to present a few points of industrial engineering and mechanical engineering and their software to help improving industrial society. Also we need your help for this important job. You can send your points of view, papers, please send be Email:mehdijavadyan@gmail.com to upload in this page with your name.Thankful

Cloud computing and emerging IT platforms
abstract
With the significant advances in Information and Communications Technology (ICT) over the last half century, there is an increasingly perceived vision that computing will one day be the 5th utility (after water, electricity, gas, and telephony). This computing utility, like all other four existing utilities, will provide the basic level of computing service that is considered essential to meet the everyday needs of the general community. To deliver this vision, a number of computing paradigms have been proposed, of which the latest one is known as Cloud computing. Hence, in this paper, we define Cloud computing and provide the architecture for creating Clouds with market-oriented resource allocation by leveraging technologies such as Virtual Machines (VMs). We also provide insights on market-based resource management strategies that encompass both customer-driven service management and computational risk management to sustain Service Level Agreement (SLA)-oriented resource allocation. In addition, we reveal our early thoughts on interconnecting Clouds for dynamically creating global Cloud exchanges and markets. Then, we present some representative Cloud platforms, especially those developed in industries, along with our current work towards realizing market-oriented resource allocation of Clouds as realized in Aneka enterprise Cloud technology. Furthermore, we highlight the difference between High Performance Computing (HPC) workload and Internet-based services workload. We also describe a meta-
negotiation infrastructure to establish global Cloud exchanges and markets, and illustrate a case study of harnessing ‘Storage Clouds’ for high performance content delivery. Finally, we conclude with the need for convergence of competing IT paradigms to deliver our 21st century vision.

ADOPTION AND DIFFUSION OFDECENTRALISED ENERGY
ABSTRACT
Energy market liberalisation, concerns about environmental pollution and climate change, and the dependence on fossil fuel imports render the adoption and of distributed generation technologies a field of research increasingly recognised as important. This paper contains a brief overview of both
commercially available and close-to-market distributed co-generation (CHP) technologies and fields of application. It also provides a thorough investigation on the adoption and diffusion of engine-based CHP systems in the German market since 1960. The empirical analysis is mainly based on a detailed data set of nearly 5,000 such systems installed in Germany until 1998. It makes use of descriptive data analysis, net present value calculations, and micro-econometric (hazard rate) modelling. We further assess market diffusion from 1998 until today and future diffusion prospects, and discuss impacts on the development that stem from liberalisation-driven energy market transformation processes. The results show that economic considerations alone do not suffice to explain the adoption decisions taken by investors, and also present some new insights with regard to the use of hazard rate models in the context of energy conversion technology adoption.

Understanding the adoption of new technology in the forest products industry
Abstract
In anticipating future rates of adoption of new technology in forest products, several uniquely important factors come into play. In this respect, the role of innovations imported from other industries, the effect of raw material shortages, the importance of economic factors in adoption
of innovations, and the problems presented by the heterogeneity of wood raw material and finished products are discussed. The nature of the adoption process and reasons for long lags between innovation and adoption are also addressed. Certain observations carry. implications for how research and information gathering should be conducted and what priorities should be accorded activities related to technology development and research in forest products.

Transfer of Technology to Developing
Abstract:
This paper analyzes national and international policy options to encourage the international transfer of technology, distinguishing between four major channels of such transfer: trade in products, trade in knowledge, direct foreign investment and intranational and international movement of people. A typology of country ‘types’ and appropriate policy rules of thumb is developed as a guide to both national policymakers and rule making in the WTO. We argue that policies should differentiate between countries. The policy recommendations made illustrate the more general need for such differentiation in the application of special and differential treatment of developing countries in the WTO.
