Development of an Energy Optimized Stirred Media Grinding Mill

The article deals with an innovative approach of combining modern simulation techniques with pilot plant testing work with the target to develop a new stirred media grinding mill. With the help of discrete element simulation various mill configurations were studied. The target was maximizing the interactions between beads and the related power consumption. Having found an optimum set-up in theory, the results were confirmed in a semi-industrial pilot mill. Based on the outcomes a robust industrial concept was engineered so as to place a new product on the market.

Automatic On-Die Impedance Matching in Current Mode Off-Chip Signaling

A system for on-die automatic impedance matching in current mode off-chip signaling is described. In order to perform the automatic matching operation, an algorithm that integrates the sign of the impedance matching error and the sign of the coupling branch current is implemented. An advantage of the proposed system is that it works without interfering with the driver operation. The transistor level circuit implementation of the system is described and computational simulations with post layout extractions are presented. Also experimental results are shown in order to prove the performance of the system.     

The performance of resilient layers made from cork granulates mixed with resins for impact noise reduction

This paper analyses the impact noise reduction of resilient layers made from cork granulates with eight different sizes, mixed with polyurethane and epoxy resins. The predicted impact sound improvement index and dynamic stiffness are compared with some commercially available underlays. According to the type of binder and particle size, the acoustical cork based layers present values of the impact sound improvement index and dynamic stiffness similar to the commercial layers used in buildings.
