1. Design for Producibility in Fabricated Aerospace Components - A framework for predicting and controlling geometrical variation and weld quality defects during multidisciplinary design
Abstract : In the aerospace industry, weight reduction has been one of the key factors in making aircraft more fuel efficient in order to satisfy environmental demands and increase competitiveness. One strategy adopted by aircraft component suppliers to reduce weight has been fabrication, in which small cast or forged parts are welded together into a final shape. READ MORE

2. Feedback Control of Robotic Friction Stir Welding
Abstract : The Friction Stir Welding (FSW) process has been under constant developmentsince its invention, more than 20 years ago. Whereas most industrial applicationsuse a gantry machine to weld linear joints, there are applications which consistof complex three-dimensional joints, requiring more degrees of freedom fromthe machines.

3. Design For Manufacturing and Producibility in Fabricated Aerospace Structures
Abstract : Aircraft component suppliers must adopt new design strategies in order to absorb market growth and become more competitive at the same time as they satisfy environmental demands. To deal with this situation, weight reduction has been the key to success and have made jet engines more fuel efficient. READ MORE

4. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings
Abstract : Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. READ MORE

5. Imaging and analysis methods for automated weld inspection
Abstract : All welding processes can give rise to defects, which weakens the joint and can eventually lead to the failure of the welded structure. In order to inspect welds for detects, without affecting the usability of the product, non-destructive testing (NDT) is needed. READ MORE
