Large Pelton turbines used in major hydro applications are of high efficiency, in the range of 92% or more. However, Peltons used in mini-hydro applications in Sri Lanka were often found to be of lower efficiency, and of ...

Membranes and membrane based separation techniques have developed rapidly over the last two decades with a considerable technical and commercial impact. The technology is now widely used for a range of applications including ...

Facilities management operates on the premises that the efficiency of any organisation is linked to the physical environment in which it operates and that the environment can be improved to increase its efficiency. This ...

As cashew nut shell liquid (CNSL) is a natural source of phenols, attempts are made in this work to prepare a synthetic polymer resin from the liquid, by treating it with formaldehyde. The polymer resin thus prepared is ...

A study has been carried out on the types of construction and factors affecting efficiency of metal melting furnaces currently used in the non-ferrous foundry sector with the objective of developing an oil-fired furnace ...

Design of continuous prismatic prestressed concrete continuous spine beams is a complex task, primarily due to the secondary moments that occur as a result of the prestressing effects. In prestressed concrete members, it ...

A methodology for designing fuzzy logic damping controllers for large practical power systems is presented in this paper. The proposed approach uses (i) the Prony Signal & Transfer Function Identification Technique to ...

A significant proportion of electrical energy generated is utilised in industrial motor drives in addition to it being used for electric lighting and heating. Also, oversized and under-utilised motors in the industrial ...

Quantitative reliability evaluation is an important aspect of power system planning and operation. The indices produced in these applications are utilised in a wide range of management decisions throughout a utility. One ...

This paper reports an experimental method developed to measure the thermal conductivity of concrete. This method involves the measurement of steady state temperature distribution across a cylindrical specimen of concrete ...
