The failure rate function and mean residual life function are two important characteristics in reliability analysis. Although many papers have studied distributions with bathtub-shaped failure rate and their properties, few have focused on the underlying associations between the mean residual life and failure rate function of these distributions, especially with respect to their changing points...

In this paper, we establish the existence of at least three solutions to a Navier boundary problem involving the biharmonic equation. The technical approach is mainly base on a three critical points theorem of B. Ricceri. AMS Subject Classifications: 34B15.

Comparison asymmetries are most often explained in terms of underlying asymmetries in the perceived similarity of the comparison items, which in turn are seen as arising from the differential weighting of distinctive features of the target and base representations. In two experiments, we fail to confirm the predictions of the standard account. Rather, comparison asymmetries seem to follow from ...

A human-in-the-loop simulation investigated how well terminal-area air traffic controllers could manage arrival traffic flying optimized profile descents on RNAV/RNP routes, while maintaining high throughput under varying environmental conditions. Scenarios were investigated with and without advisory tools and improved displays, and also examined how well controllers could cope with off-nominal...

The goal of this work is to recover the spatial layout of indoor environments from omnidirectional images assuming a Manhattan world structure. We propose a new method for scene structure recovery from a single image. This method is based on line extraction for omnidirectional images, line classification, and vanishing points estimation combined with a new hierarchical expansion procedure for d...

BACKGROUND Studies assessing the point-specific effect of acupuncture or the characteristics of acupuncture points (APs) tend to yield inconclusive results. In order to identify a possible confounding factor, we aimed to examine the variability in AP localization by means of a survey. MATERIAL AND METHODS Attendees of the 14th ICMART (International Council of Medical Acupuncture and Related T...

BAN estimators generally admit first order representations which insure them to be also asymptotically Pitman closest. For AN estimators admitting a first order representation, an ordering under the Pitman closeness measure is established and is shown to be isomorphic to the one under 'the usual quadratic norm. Multiparameter problems are also treated in the same vein.

We continue the study of a lattice-ordered ring G(X), associated with the ring C(X). Following [10], X called RG when G(X) = C(Xδ). An RG-space must have a dense set of very weak P-points. It must have a dense set of almost-P-points if Xδ is Lindelöf, or if the continuum hypothesis holds and C(X) has small cardinality. Space which are RG must have finite Krull dimension when taken with respect ...
