Abstract: A self-test mechanism within an integrated circuit to automatically interleave evaluation of a clock signal by a clock monitor unit with periodic testing for faulty operation of a clock monitor unit implemented within the integrated circuit for monitoring a clock signal. The mechanism injects faults into the clock monitor unit to evaluate if the clock monitor unit is operating in accordance with its specified operating parameters. The injected faults are intended to cause the clock monitor unit to determine that the clock signal is operating outside of a specified frequency range. If the injected faults do not cause the clock monitor unit to determine that the clock signal is operating both above and below the specified frequency range, then the clock monitor unit is not functioning according to specified operating parameters.

Abstract: The proper visualization of a business process plays a key role in analyzing, changing, simulating and monitoring the business process. Most BPMS systems today, provide a modeling environment where the business user can define and visualize business processes as BPMN diagrams. Some more advanced systems (such as Savvion Business Manager) enable monitoring of the business process at run-time via a color-coded view of the process diagram. While process diagram is an important view of the process, it lacks the level of abstraction needed to provide information in an optimal way to the business users. The proposed visualization, called the 360 degree view provides an optimal view of a business process without losing important details about the process.

Abstract: Methods of using acoustic emission (AE) as a condition assessment technique for alkali-silica reaction (ASR) in concrete are provided. ASR is a chemical reaction occurring between alkaline hydroxides within cement past and certain types of amorphous silica found in mineral aggregates. ASR causes an accumulation of internal pressure due to the formation of a hygroscopic gel which leads to expansion and cracking of the concrete. AE is highly sensitive to stress waves emitted from a sudden release of energy such as formation of cracks in concrete. This allows it to capture and identify propagating damage. AE has the potential to detect micro-cracks forming prior to expansion, which can be related to the degree of ASR damage.
