This paper analyzes the effect of input profile selection on software testing using the concept of fault detectability profile. It shows that optimality of the input profile during testing depends on factors such as the planned testing effort and the fault detectability profile. To achieve ultra-reliable software, selecting test input uniformly among different input domains is preferred. On the...

This paper investigates the detectability of delayed Boolean control networks (DBCNs) via semi-tensor product (BSTP) method. Firstly, three concepts weak detectability, strong and for DBCNs are proposed dynamics DBCN converted into an equivalent algebraic form. Secondly, a full-order observer is constructed to judge detectabilities by using BSTP. Thirdly, based on observer, some necessary suffi...

The aim of this study is to investigate the impact of respiratory motion correction and spatial resolution on lesion detectability in PET as a function of lesion size and tracer uptake. Real respiratory signals describing different breathing types are combined with a motion model formed from real dynamic MR data to simulate multiple dynamic PET datasets acquired from a continuously moving subje...

We measured the detectability of a single line (target) flanked by high-contrast inward- or outward-pointing arrowheads (context). We show that as a function of target contrast, context angle, and context position there is a continuum of contextual modulations of target detectability that vary from strong inhibition (target detection is impaired) to strong excitation (target detection is facili...

It is well known that as a consequence of local nature of general relativity, the global topology of space-time remains undetermined by the Einstein’s field equations. This coupled with the enormous recent increase in high resolution cosmological observations has led to a great deal of interest in the possibility that the universe may possess compact spatial sections with a non-trivial topology...

Detectability of individual animals is highly variable and nearly always < 1; imperfect detection must be accounted for to reliably estimate population sizes and trends. Hierarchical models can simultaneously estimate abundance and effective detection probability, but there are several different mechanisms that cause variation in detectability. Neglecting temporary emigration can lead to biased...
