More powerful process design methods and tools of sheet metal stamping are needed to help engineers design better products, to reduce lead times and costs, and to increase product performance and accuracy. A novel model for representation of object-oriented case information constitution relationship is presented, ‘Class-Property’ structure is proposed in order to refine the case representation,...

In multiple operation stamping processes, a press tonnage signal measured by press tonnage sensors installed on press linkages/uprights, is the summation of die forces at all stations. Different from the current practice of using a whole cycle of press tonnage signals to monitor the compound condition of all stations, this paper proposes a new method to use the partitioned monitoring segments o...

This technical report gives detail on the results obtained from testing of the ASUS P5LD2-VM Motherboard with Intel network interface cards (Intel 10/100 and Onboard Intel PRO/1000 PCI Express) for time stamping accuracy. The hardware is tested for the purposes of being a Flow Meter in our prototype ANGEL QoS architecture. A number of affecting factors have been investigated, including the link...

We study queueing strategies in the adversarial queueing model. Rather than discussing individual prominent queueing strategies we tackle the issue on a general level and analyze classes of queueing strategies. We introduce the class of queueing strategies that base their preferences on knowledge of the entire graph, the path of the packet and its progress. This restriction only rules out time ...

Functional, three-dimensional (3-D) nanostructures and microstructures on surfaces can serve as excellent molecular templates for applications in optoelectronics and biotechnology. Coupling stable, amphiphilic films with hydrophobic biological molecules can yield biomimetic interfaces able to reproduce biological functions in vitro. Recently, thin films of amphiphilic molecules have been used t...
