Reducing CO2-emissions from electricity-generating power-plants is a high priority. Several advanced low-carbon power-plants have gained wide acceptance. Uncertainties concerning future costs and performances of new pertinent technologies and unit fuel-prices as well as the types and the...

Despite inflating unit-fuel costs, the long-term prospects for the aircraft industry remain buoyant. Nevertheless reducing direct operating-costs is crucial to ensure competitive advantages for airlines and manufacturers, and so effective advanced engine-condition monitoring methodologies are...

A diagnostic process capable of providing an early warning of a fault in a gas turbine is of tremendous value to the user and can result in substantial financial savings. The approach in the Genetic Algorithm based technique adopted is to treat the problem of engine diagnostics as an...

Technological advances and high cost of ownership have resulted in considerable interest in advanced maintenance techniques. Quantifying fault and consequently availability requires the use of gas-turbine and combined-cycle models able to undertake appropriate diagnostics and life-cycle costing....

Although considerable progress has been achieved in supplying electricity to most parts of Oman, due to its population dispersion, economic constraints and the short duration of the national electrification-programme to date (i.e. less than 30 years), there are still some locations without this...

In 1970, only 10 km of asphalt road and neither a modern airport nor a major seaport existed in Oman. However, by 1996, there were more than 6500 km of asphalt roads, two major seaports and two international airports. The number of motorised vehicles had grown from almost zero in 1970 to...

A coalfield, in excess of 120x106 tonnes of coal in situ, has been discovered at Al-Kamil in south-eastern Oman. The coal is classified as highly-volatile bituminous type-A, with an average calorific value of 27.5 GJ per tonne. Unfortunately, it has on average ~5% by weight sulphur content and...

Most members of the general public tend to regard their homes and the buildings in which they work as relatively safe havens from the physical and chemical stresses of the ambient environment. However, during recent decades a hazardous phenomenon concerning the built environment has become...

Macro and micro hydropower systems are described, along with a consideration of the technical and environmental problems involved. A case study, with Bargoed in the Rhymney Valley, South Wales as the proposed site is then presented, with some of the issues involved when choosing a specific...

Whilst discounting the likely, frequent widespread use of natural wetlands for liquid-effluent treatment within the UK, a brief history of the global development of constructed wetlands is given. The designs and types of flora and fauna used within UK-based constructed wetlands, are discussed....
