The environmental impact of information and communications technologies (ICT) might be a two way street. On the one hand, each stage of the ICT lifecycle has a potential to contribute to the damage of the environment. On the other hand, ICT can provide some of the best tools not only in measuring and reporting greenhouse gas emissions, waste and water use within core enterprise and value chain ...

Based on the background of Gutian country-level green-way planning project, this essay carries out suitability evaluation and empirical study of green-way network selection based on GIS.The main study contents include: According to the green-way network selection principles and analysis of basic construction conditions,taking overlay analysis of GIS quantitative suitability , and putting forwar...

Information technology (IT) and communications technologies are promoting new virtual forms of business enterprises based on teleworking. Performance issues relating to organisation form, depend much on the performance and interworking of technology, infrastructure, and working practice. The cellular Green-Team approach as practiced at a heavy engineering Small-to-Medium sized Enterprise (SME) ...

In this paper, we propose an optimization model that considers two pathways for injecting renewable content into natural gas pipeline networks. The include (1) power-to-hydrogen or PtH, where off-peak electricity is converted to hydrogen via electrolysis, and (2) power-to-methane, PtM, carbon dioxide from different source locations methane (also known as synthetic gas, SNG). above result in gre...

reducing the number of colors in an image while preserving its quality, is of importance in many applications such as image analysis and compression. it also decreases memory and transmission bandwidth requirements. moreover, classification of image colors is applicable in image segmentation and object detection and separation, as well as producing pseudo-color images. in this paper, the kohene...

Green waste is a key component of California’s solid waste stream and so is an important target for effective waste diversion. The California Integrated Waste Management Board (CIWMB) reports that about 15 million cubic yards of organics comprised largely of green waste are diverted annually in California. The diverted organics are principally used as compost and mulch in agricultural and urban...

This paper critically reviews research conducted from 1999-2013 on Green Logistics Network Design (GrLND). Basic features like decision variables, network structure, type of optimization techniques preferred, components of objective functions considered across various industries to improve their environmental performance has been identified. Finally, potential gaps for future studies are highli...

Communication networks are becoming more essential for our daily lives and critically important for industry and governments. The intense growth in the backbone traffic implies an increment of the power demands of the transmission systems. This power usage might have a significant negative effect on the environment in general. In network planning there are existing planning models focused on Qo...

klinkenberg permeability is an important parameter in tight gas reservoirs. there are conventional methods for determining it, but these methods depend on core permeability. cores are few in number, but well logs are usually accessible for all wells and provide continuous information. in this regard, regression methods have been used to achieve reliable relations between log readings and klinke...
