Leaks are present to some extent in all water-distribution systems. This paper proposes a leakage localization method based on pressure measurements and the application of principal component analysis to the fault diagnosis in water distribution systems. First, some theoretical basics are introduced, from model building and modeling the fault effects to monitoring. Then a simple hydraulic case study...
License plate recognition is the key of the intelligent transport monitoring system and the rate of license plate type identification is one of the important technical specifications in this recognition system. This paper proposed a new method based on clustering and neural network to identify the license plate type. The experimental results of more than 500 images acquired under different conditions...
An organizational level test strategy needs to incorporate metrics to make the testing activities visible and available to process improvements. The majority of testing measurements that are done are based on faults found in the test execution phase. In contrast, this paper investigates metrics to support software test planning and test design processes. We have assembled metrics in these two process...
