The universal factory floor communications protocol MTConnect allows the exchange of information between shop floor equipment and software applications. Data from shop floor devices is collected by a piece of software called adapter. The adapter sends the data to a local webserver called agent, which associates the data with an information model and makes machine data available to clients in un...

A linear knife grid device was developed for first-stage size reduction of high- and low-moisture switchgrass (Panicum virgatum L.), a tough, fibrous perennial grass being considered as a feedstock for bioenergy. The size reduction is by a shearing action accomplished by forcing a thick packed bed of biomass against a grid of sharp knives. The system is used commercially for slicing forages for...

Accurate measurement data are crucial for correct understanding of traffic. Ever increasing bandwidth pushes the requirements for measurement equipment beyond pure SW/PC solutions. We developed a scalable architecture of a hardware-supported, passive measurement platform, the IMP, for high-precision traffic measurement for Gigabit Ethernet with flexible filter possibilities and intelligent sele...
