In this paper we examine the inevitable interconnection between engineering, economics and environmental impact in the electricity industry, and how they shape the roles engineers can and should play in designing the energy systems of the future. Involvement of engineers needs to happen in two ways: engineers can bring a technological awareness to the policy debate; and engineers need to be able to...
Electronic noses are intelligent designs that are able to classify and quantify different gases/ odors. This concept permits us to easily provide remote connectivity, large data storage and complex signal processing by using commercial sensors. In this paper a case study is presented for examining the use of sensor grid system concerning urban air pollution monitoring for carbon monoxide, carbon dioxide...
Doing business in the United States today means focusing on creating a greener, more energy efficient product. Though industry in general - globally and domestically - has been aware of the need for more eco-friendly products for a while now, it is really only in the last three years that major American corporations have truly begun to focus on the need to be green. Here in the telecommunications...
In this paper, the author introduces a new technique. Adopt adaptive fuzzy controller to greenhouse to achieve the greenhouse control of environmental factors. Firstly, the general structure design of the system was introduced. Secondly, descript the hardware designing, and determine the systempsilas structure and working principle. It was with emphasis on the design of an intelligent controller,...
The ambiance in virtual environments is affected by the loss of multimodal information. For many purposes, the affective qualities of a virtual environment require special attention in the modeling process. In order to construct the right ambiance it can be beneficial to engineer the affective appraisal of the virtual environment. However, a userpsilas assessment of the affective qualities of a (virtual)...
The methods of energy, exergy, and life cycle analysis are applied to a new nano-manufacturing process producing 40 nm titanium dioxide particles. The use of identical boundaries for each analysis allows for direct comparison of the results from each method. It was found that the thermodynamic methods identify spray hydrolysis as a significant sink in the process and life cycle analysis shows it to...
In addition to moving itself in a greener direction and leveraging other environmental initiatives, IT could help create green awareness among IT professionals, businesses, and the general public by assisting in building communities, engaging groups in participatory decisions, and supporting education and green advocacy campaigns. Along these lines, tools such as environmental Web portals, blogs,...
Coal-fired power plants produce flue gas containing a number of air pollutants including carbon dioxide (CO2), a major greenhouse gas contributing to climate change. Capture of CO2 from the flue gas at the coal-fired power plants is one of the strategies to help Canada reduce its CO2 emissions, achieve its Kyoto protocol reduction target, and also ensure the continuation of fossil fuel utilization...
The extended environmental impact of e-learning was studied including ripple effects. E-learning changes the user's lifestyle and the various changes (ripple effects) were quantified by using an Internet questionnaire. The environmental burdens were evaluated with LCA and the results were shown as carbon dioxide (CO2) emissions. E-learning can reduce the CO2 emissions generated by conventional training...
