Many prominent smart contract applications such as payment channels, auctions, and voting systems often involve a mechanism in which some party must respond to challenge or appeal action within fixed time limit. This pattern of challenge-response mechanisms poses great risks if, during periods high transaction volume, the network becomes congested. In this case, fee market competition can preve...

Process Mining is the discovery of business processes from log files. One application is ensuring conformance to prescribed processes or business rules. Businesses operate in real time, needing to quickly react to change. We consider requirements for process mining to support this: a notion of real time, and methods to compare processes and detect significant change. We present initial results ...

The plasma process is often used in the fabrication of semiconductor wafers. However, due to the lack of real-time etching control, this may result in some unacceptable process performances and thus leads to significant waste and lower wafer yield. In order to maximize the product wafer yield, a timely and accurately process fault or abnormal detection in a plasma reactor is needed. Optical emi...
