Fault-Tolerant Observers Supervisor: Dr Imad M. Jaimoukha Designing of a robust fault-tolerant observer that guarantees a certain level of performance for real-time applications. By: YEO Zhi-Wei‚ Laurence 00566245 Overview For any system such as a factory plant‚ an aircraft jet engine system or a water pumping system‚ it can be replicatedi by a mathematical model which includes the affecting dynamics based on observations and assumptions. However‚ it would be practically challenging

equation. Impure heteroskedasticity is caused by a specification error such as an omitted variable. -Pure heteroskedasticity does not cause bias in the coefficient estimates. However‚ it typically causes OLS to no longer be the minimum-variance estimator. The error term causes the independent variable to fluctuate more‚ increasing their variance. Moreover‚ the OLS estimates of the standard errors become biased‚ leading to unreliable hypothesis testing. Heteroskedasticity increases the variance of

and present how to derive the standard error for equal interval variables‚ binomial variables‚ and ratios of two variables. The latter‚ as described earlier‚ is commonly used in rapid surveys and is termed a ratio estimator.

more than twenty years ago and much of the estimating experience and data was lost in the decades where the company had an operational focus. This coupled with the shortage in the construction industry of suitably experienced cost engineers and estimators has made it difficult for the author to build up the organisational capacity within this functional area. In addition expert resources that have chosen to remain in the field and in the organisation are an ageing workforce approaching retirement
