The depth distribution of strain and composition in graded Al x Ga1 - x N films and nanowires (NWs) are studied theoretically using the kinematical theory of X-ray diffraction. By calculating [Formula: see text] reciprocal space maps (RSMs), we demonstrate significant differences in the intensity distributions from graded Al x Ga1 - x N films and NWs. We attribute these differences to relaxatio...

There is a long history of research into depth percepts from very large disparities, beyond the fusion limit. Such diplopic stimuli have repeatedly been shown to provide reliable depth percepts. A number of researchers have pointed to differences between the processing of small and large disparities, arguing that they are subserved by distinct neural mechanisms. Other studies have pointed to a ...

Deep vertical line arrays can exploit the reliable acoustic path (RAP), which provides low transmission loss (TL) for targets at moderate ranges, and increased TL for distant interferers. However, nearby surface interference also has favorable RAP propagation and cannot be separated from a submerged target without horizontal aperture. In this work, a physics-based Fourier transform variant is i...

In the past few years several systems for object reconstruction based on the analysis of 2D images have been proposed. In order for such systems to be of practical use, the 3D data extraction process is expected to be fast and reliable. In this paper we propose a general approach for the reconstruction of complete objects based on a mesh fusion algorithm. Every surface patch is obtained as a de...

A critical challenge in the creation of autonomous mobile robots is the reliable detection of moving and static obstacles. In this paper, we present a passive vision system that recovers coarse depth information reliably and efficiently. This system is based on the concept of depth from focus, and robustly locates static and moving obstacles as well as stairs and dropoffs with adequate accuracy...

Recovering tissue deformation during robotic assisted minimally invasive surgery is an important step towards motion compensation and stabilization. This paper presents a practical strategy for dense 3D depth recovery and temporal motion tracking for deformable surfaces. The method combines image rectification with constrained disparity registration for reliable depth estimation. The accuracy a...

patients warranted additional i.v. anaesthetic prior to application of the electrical stimulus. Fortunately, neither of the patients reported awareness of the procedural events. Consequently, we no longer use bispectral index monitoring alone to assess pre-ictal anaesthetic depth in patients receiving ECT. Moreover, Zand and colleagues recently reported that the BISwas not a reliable monitorof ...

Introduction: Previous studies have suggested that Bispectral Index (BIS) may be less reliable in detecting depth of anesthesia or sedation during use of certain anesthetics or sedatives. These studies suggest that depth of sedation as measured by BIS may be drug-dependent. To date, data related to the effects of sedative agent on BIS in children are limited due to small sample sizes and inclus...

We examine the contribution of colour for the computation of depth maps from a stereo pair of colour aerial images. As a matter of fact we propose an original method based on fusion theory to compute dense and reliable depth maps. The fusion is directly applied on correlation curves obtained for each colour channel. In order to evaluate the quality of the elevation map, we compare our results t...
