Substation insulators near coastal areas rapidly become polluted due to the salty wind blowing in from the sea. Hazardous levels of pollution deposit cause higher leakage currents under damp conditions, resulting in system ...

A laboratory workcell has been developed for fish cutting. The workcell, which uses a variety of sensors, actuators, and hardware for component interface and control, operates with the help of a dedicated supervisory ...

High strength concrete can be used in high-rise buildings to minimise the size of columns, especially in the lower floors. High strength concrete has the added advantage of a higher elastic modulus that can reduce the ...

This paper presents design and construction details of a six-bladed horizontal axis wind mill suitable for small scale lift irrigation. The main outcome of the study is the improvement of the rotor performance by ...

Tension free or uniform minimum tension fabric laying is essential in order to overcome the problems of distortion of garment panels. Some garment factories use machine laying while others lay manually Even with tension ...

Storm‐water drainage and salt‐water exchange are two important phenomena which should be incorporated in an environmental management programme of an estuarine ecosystem. This paper presents the results of an investigation ...

This paper describes a future scenario where optical links are used for interlinking data super highways. Conventionally, optical carriers are used in guided form where it travels within an optical fibre. However, in ...

Porous vertical structures have been used for coast protection and for harbour structures. In the case of harbours these structures have been used as the principal breakwaters and as internal structures. The ability to ...

The Humphreys Spiral Concentrator which was developed in 1943 is now being used extensively for the concentration and the recovery of heavy minerals. In Sri Lanka, this device is very effectively used by the mineral sand ...

Cost control is very important for any industry, since it is the activity which monitors the actual cost against the budgeted costs and initiates corrective actions if the costs are higher than expected. The estimating ...
