1. Constrained optimization of rotor-bearing systems by evolutionary algorithms
Abstract : In the design of mechanical components and systems, nature has often been the source of inspiration. It is easy to point out solutions in nature that are optimal in some sense. One example is the structure of the surface of a shark's skin. This is designed by nature to minimize the resistance when the shark swims in the water. READ MORE

2. Kinetic Energy Storage and Magnetic Bearings : for Vehicular Applications
Abstract : One of the main challenges in order to make electric cars competitive with gas-powered cars is in the improvement of the electric power system. Although many of the energy sources currently used in electric vehicles have sufficientlyhigh specific energy, their applicability is limited due to low specific power. READ MORE

3. Blast furnace coke properties and the influence on off-gas dust
Abstract : In blast furnace ironmaking, efforts are made to decrease the coke consumption mainly by increasing the pulverized coal injection rate. This will cause changes in in-furnace reduction conditions, burden distribution and demands on raw material strength, etc. READ MORE

4. Bearing the brunt of warming: Interactions between carbon and hydrology in northern Sweden
Abstract : Climate modelling studies indicate that subarctic ecosystems are predicted to show some of the earliest responses to climate change. The predicted temperature and precipitation changes have implications for the carbon biogeochemical cycle with ancillary effects in permafrost soils, vegetation, and stream networks. READ MORE

5. On the effect of nitrogen, hydrogen and cooling rate on the solidification and pore formation in Fe-base and Al-base alloys
Abstract : Experiments on the production of porous metallic materials were performed on Fe-base and Al-base alloys. The method involves dissolution of gases in the liquid state and solidification at various cooling rates. The alloy compositions were selected to induce solidification of primary particles intended to control the pore distribution. READ MORE
