    Astronomical Distance Determination in the Space Age: Secondary Distance Indicators

    Get PDF
    The formal division of the distance indicators into primary and secondary leads to difficulties in description of methods which can actually be used in two ways: with, and without the support of the other methods for scaling. Thus instead of concentrating on the scaling requirement we concentrate on all methods of distance determination to extragalactic sources which are designated, at least formally, to use for individual sources. Among those, the Supernovae Ia is clearly the leader due to its enormous success in determination of the expansion rate of the Universe. However, new methods are rapidly developing, and there is also a progress in more traditional methods. We give a general overview of the methods but we mostly concentrate on the most recent developments in each field, and future expectations. © 2018, The Author(s)

    Active Fault Diagnosis using Moving Horizon Input Design

    No full text
    This article considers the design of an input signal for improving the diagnosability of faults from process measurements. Previous work has focused on open-loop input design. In particular, deterministic methods are available for computing an input that guarantees fault diagnosis within a specified time horizon, whenever such an input exists. Here, two closed-loop approaches are considered that use feedback in order to reduce the length and/or cost of the required input, while maintaining this guarantee. The first method uses an existing open-loop input design method within a receding horizon framework. The second method approximates the first by an explicit feedback law in order to reduce online computations
