Green house gases, comprising of water vapour, nitrous oxide, carbon dioxide and methane are the main contributors for the cause of global warming which is a risk to the earth's climate and ecosystem. Recent events ranging from flash floods to hurricanes and heat waves to extreme cold temperatures have shown how erratic the weather has become. Thus far, these weather patterns have shown no signs of improvement. According to a United Nations (UN) report, these green house emissions that are...
Contaminated land risk in Gui Yu arises from the disordered heap of electronic wastes and primitive processing of them. The single largest pollution source is the recycling depot where people stockpile unprocessed electronic wastes. Other contamination sources (such as stoves used to smelt circuit boards) scattered unevenly in the town since most workers/ residents store and recycle e-wastes at their home. Therefore, the team decides to take a targeted sampling strategy with the geographical...
For a long time, the world has been relying on energy from fossil carbon that has for many reason dominated the energy market because it is easy to transport, among other reasons. As time passes by, the energy on earth is increasing. The earth itself from its mode of formation absorbs solar energy from the sun and stores it in its epicenter and it can not emit it back in the same rate. This adds to the many forms of energy that man is creating and using everyday. Therefore, the energy at man's...
Over the past decade, the Information and Communication Technology (ICT) industry has become one of the fastest growing industries in several countries in the world including Mauritius (Kencki, 2008). The number of Business Process Outsourcing (BPO) and Information Technology (IT) companies has been constantly increasing similar to the number of users utilising computers and Internet at home or educational institutions. Also, more and more companies and organisations are now adopting IT...
Our climate is rapidly changing all around us. Ice is melting, plants are dying, animals are in danger, and habitats are being destroyed. The Arctic is greatly affected. The ice is melting and causing water levels to rise, and animals are dying because of loss of habitat. Over the past one hundred years, the average surface temperature has risen a little over 1 degree Fahrenheit. (Baker, 4) Climate change happens because of humans and natural reasons. Humans are not being careful and are not...
Material and energy resources management includes the proper selection, installation and managerial of it in manufacturing will give impact on the production process, energy consumption and even reduce the pollution. Manufacturer objective towards sustainable manufacturing is maximize the production while minimize the usage of material and energy resources because the price of the material and energy had increased due to depleting of materials and non-renewable resources (Leahu S., 2012). The...
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...
