This paper presents the results of work undertaken to develop and test contrasting data analysis approaches for the detection of bursts/leaks and other anomalies within wate r supply systems at district meter area (DMA)level. This was conducted for Yorkshire Water (YW) sample data sets from the Harrogate and Dales (H&D), Yorkshire, United Kingdom water supply network as part of Project NEPTUNE EP/E003192/1 ). A data analysissystem based on Kalman filtering and statistical approach has been developed. The system has been applied to the analysis of flow and pressure data. The system was proved for one dataset case and have shown the ability to detect anomalies in flow and pres sure patterns, by correlating with other information. It will be shown that the Kalman/statistical approach is a promising approach at detecting subtle changes and higher frequency features, it has the potential to identify precursor features and smaller l eaks and hence could be useful for monitoring the development of leaks, prior to a large volume burst event.

The People

This study aims to find out the effect of event and publicity towards brand awareness on Indonesia Financial Service Authority, usually called with its abbreviation OJK. The research background is because OJK was newly established as a financial service authority, replacing Bank Indonesia. Therefore, exploring the awareness of the people about the function of OJK is interesting to be a research subject.This method used in this study is the quantitative method with 82 samples as the questionnaire respondents. The population chosen was an OJK’s event held at LPPI and Indonesia Banking School with 122 participants. Validity, reliability, normality, multicollinearity, heteroskedasticity, correlation, determination, regression, hypothesis and ANOVA tests are used as a statistical approach in order to define the outcome of the survey. The results of this study are both event and publicity have a positive and a significant influence towards brand awareness partially and simultaneously. As the conclusion, OJK should continue its programs. On the other hand, OJK should find another public relations strategy to accelerate people awareness about the duties of OJK.
