1. Wave-actuated Preform Infiltration Routines in MMC Production
Abstract : The implementation of highly magnetostrictive wave-actuator techniques in preform infiltration processes for metal-matrix composite production is described. Metal matrix materials require additional methods to handle the content, shape and position of the ceramic reinforcements, which are not required for metal alloy casting. READ MORE

2. Modelling tools for quieter vehicles : Waves in poro– and visco–elastic continua
Abstract : New modelling tools intended to contribute to the development of components for quieter vehicles are developed. The tools are based on continuum models for wave propagation in poro– and visco–elastic media. By using geometric attributes of the studied components, the computational cost may be radically decreased compared to traditional methods. READ MORE

4. From Molecular Catalysts to Hybrid Electrodes: A Theoretical Guide
Abstract : The industrial revolution thrived our society to great technological advancement and a shift from an agrarian to an industrial society. Besides this fact, the side effect has been the development of a society highly dependent on energy, and the main sources of energy are based on non-renewable fossil fuels. READ MORE

5. Gap Waveguide Technology for Millimeter Wave Applications and Integration with Antennas
Abstract : The increasing advance of short range wireless communications requiring high data rates and the lack of available spectrum have driven researchers and industry to move towards higher frequencies, in particular to the millimeter wave range. The opening of this wide portion of free spectrum has risen a large interest in developing mm-wave communication systems for commercial applications. READ MORE
