As the DTI launch a new wave energy programme, this publication reviews recent advances in each of the relevant technologies and presents it to a wider audience.

The text explores the use of numerical simulation as a support for the design and fabrication of welded components. The papers cover such topics as: welding residual stress and distortion simulation; friction stir welding; and the integrity of welding joints.

This text reviews the present status and future potential of the different systems of energy storage, their role in power generation by renewables specifically, and the electricty market generally.

Powder metallurgy (PM) is a highly attractive process because it permits the production of unique parts with unique properties by controlling their microstructure. Since the processing route for these materials is quite different from traditional engineering materials, it is vital that the PM process is understood and the potential offered by components made via this route needs to be fully integrated with the design process.

Looking at aerospace transmission technology, this text examines design configurations, materials, analysis and testing techniques, manfacturing processes, and maintenance aids that together can satsify the increasing demands on systems.

Review of pneumatic conveying; vacuum versus positive pressure; solving throughout and blockage problems; understanding and controlling attrition and wear; particle attention and deposition; conveying fragile materials; pneumatic conveying systems associated with high pressure systems.
