The objective of this study is to find an effective stimulation and measurement strategy to improve distinguishability for head EIT. To better understand the relationship between distinguishability and various strategies (stimulation/measurement patterns) for a set of electrodes, we evaluated a realistic head model and a range of common strategies.

Distinguishability and predictability appear in different complementarity relations. Englert Bergou pointed out the possible connection among distinguishability, predictability, entanglement. They conjectured that an entanglement measure was hidden between measures of distinguishability predictability. Qureshi connected these quantities for a particular trio measures. In this letter, we define ...

Distinguishability takes a crucial rule in studying observability of hybrid system such as switched system. Recently, for two linear systems, Lou and Si gave a condition not only necessary but also sufficient to the distinguishability of linear systems. However, the condition is not easy enough to verify. This paper will give a new equivalent condition which is relatively easy to verify.

Recent times have seen a spurt of research activity focused on "completing" certain wave-particle duality relations using entanglement or polarization. These studies use relation involving path-predictability, and not path-distinguishability. Quantum origins these results are explored here, in the more general framework multipath quantum interference. Multipath interference with path-detector i...

i . The notation r(◊) is here used to emphasize that the output of r depend on the fault realization ◊. In Paper 1, a quantitative fault diagnosability measure is proposed where (2.4) is computed based on the model instead of the residual r, and is called distinguishability. A graphical visualization of distinguishability is shown in Figure 2.4 where the fault modes fi and fj are represented by Zf

Multimode two-particle systems show interference effects in oneparticle detections when both particles have common modes. We explore the possibility of extending the usual concepts of distinguishability and visibility to these types of systems. Distinguishability will refer now to the balance between common and different modes of a two-particle system, instead of the standard definition concern...

We consider deeply the relation between the orthogonality and the distinguishability of a set of arbitrary states (including multi-partite states). It is shown that if a set of arbitrary states can be distinguished by local operations and classical communication (LOCC), each of the states can be written as a linear combination of product vectors such that all product vectors of one of the state...

A number of recent interference experiments involving multiple photons are reviewed. These experiments include generalized photon bunching effects, generalized Hong-OuMandel interference effects and multi-photon interferometry for demonstrations of multiphoton de Broglie wavelength. The multi-photon states used in these experiments are from two pairs of photons in parametric down-conversion. We...

BACKGROUND For any radiologist, intra-observer agreement in observing and decision making in diagnosis of any disease is of great importance, and so is observing and reading ultrasound pictures of ovarian masses and distinguishing amongst their categories. AIMS In this study, the reliability and consistency of ultrasound diagnosis of ovarian tumors have been evaluated. SETTINGS AND DESIGN T...
