Each year, the Electrical and Electronic Equipment are manufactured in ample quantities. This in turn has increased the amount of equipments that end up as e-wastes at the final stage of their product life cycle. For example, within the UK over a million tonnes of electrical and electronic goods are discarded each year. To address the problem of the growing level of waste in electrical and electronic equipment, the WEEE (Waste Electrical and Electronic Equipment) and RoHS (Restriction of...
The objectives of this study are to examine the role of ESI for scoring the risks posed by pipelines to the environment as well as to indicate the risk scores in location-based maps. A relative semi-quantitative approach based on land uses and High-Value Areas (HVAs) was carried out. A geographical information system (GIS) as a tool was employed to create novel maps related to environmental risks using rational mathematical equations. The main logic for using the equations was the...
Abstract-This project involves the simulation and study of a simple Orthogonal Frequency Division Multiplexing (OFDM) system as an application of Digital Signal Processing. The area of focus is the signal processing block of the system which uses Fast Fourier Transform(FFT) engines to achieve orthogonality of channels and thereby improve the transmission channel utilization. The system is simulated using MATLAB and it involves transmission of a digitized audio file through an additive...
Yield monitors are a new and powerful tool for the implementation of precision agriculture throughout a farm. Yield monitor applications and advantages are discussed in this case study. The adoption of such systems might be the future of agriculture, however everything comes with a cost. In order for a farmer to be convinced to use the latest application he needs to reassure that he profit generated is enough to cover the initial cost and in the future add to his production performance. The...
During the year 2001 to 2003 , there were four companies named ProdiGene, Monsanto, Hawaii Agriculture Research Center and Garst seed who had planted genetically modified corn and sugarcane on certain locations in Hawaii. These crops were genetically modified to produce plants which would contain hormones, vaccines or proteins which could be used to treat certain human diseases. These companies had permits to plant genetically modified sugarcane and corn from the United States Department of...
What is Organic Home? The concept of Organic Home is fixing the solar energy may use to photovoltaics, passive heating, daylighting, and water heating and also fixing rain water harvesting system, independent house sewage system and recycle. However, people tend to carry a higher price tag with it. Some people will think that installment and maintenance cost for Green Building is more expensive. They do not understand that in a long term period the organic building will be more economic. Aim...
Water plays a vital role in life. Without water, existence of life is not possible. Without water, agriculture is not possible. Without agriculture, we cannot meet the ever rising demand for food. Climate change, as we all know is disastrously affecting our environment and the ecological balance. Glaciers, ice bergs and the north and south poles are melting at a rate higher than ever. This is greatly changing the water cycle. Climate change thus severely affects the water levels. Climate change...
Paper production is the fourth most energy- intensive of all manufacturing industries and one of the most polluting industries. The use of so much paper comes at a significant environmental cost. In the last decade, many large paper purchasers have recognized the environmental impacts associated with paper and changed their practices accordingly. Whether driven by consumer demand, governments purchasing directives, cost savings, or management commitment, these companies are using less paper,...
In 18th century, the term sustainable development is still not recognized by the public. However, until 1898, Ebenezer Howard conceived the concept of Garden City where settlements and their surrounding countryside are interdependent, and do not deplete the resource and environment around. This advocate of creating a healthy working and living environment is deemed as one of the origins leading to future discussion about the "sustainable development". (Blowers, 1995) Kan Until 1962,...
Currently, the world is suffering energy crises and entering a period of energy transition. And many people have recognized that the industrialized world must rely on renewable energy rather than fossil fuels. Although fossil fuels are the dominant energy source in the modern global economy for the past few centuries, which had helped drive the industrial revolution and promoted the material prosperity. However, fossil fuels will not last forever. The World Energy Council (WEC, 2004) suggests...
