| Detection of incipient (slowly developing) faults is crucial in automated maintenance problems where early detection of worn equipment is required. In this note, a general framework for model-based fault detection and diagnosis of a class of incipient faults is developed. The changes in the system dynamics due to the fault are modeled as nonlinear(More)
The increasing importance of Unicode for text files, for example with Java and in some modern operating systems, implies a possible doubling of data storage space and data transmission time, with a corresponding need for data compression. However it is not clear that data compressors designed for 8-bit byte data are well matched to 16-bit Unicode data. This(More)
