Calculating Staircase Slope from a Single Image
… within any multistory environment is the staircase. Staircases are difficult to model because of their uneven surface and various depth aspects. Coupling this need is a variety of ways to reach this goal. Unfortunately, many such methods rely upon specialized sensory equipment, multiple …

Temperature and salinity variability in thermohaline staircase layers
… salinity and velocity profiles in a thermohaline staircase. Variations in the intensity of layering and the evolution of layer properties are well documented during the 4.3 month record. Such staircases are the result of strong salt fingering at the interfaces between the mixed layers, and these …

Determination of advection and diffusion in a thermohaline staircase region
Thermohaline staircases consisting of a series of well mixed layers approximately 30 m thick are found at depths of 300-500 m in a region of the tropical North Atlantic spanning 48° to 58°W, 8° to 17° N. Density ratios ( ... ) with values near 1 indicate a double diffusive origin for the structure …

A comparative study of the change in diatom inferred ph of a staircase of lakes in the Algoma District, Northern Ontario /
Four staircase lakes occupying a single watershed located in the Algoma District, north of Lake Superior were chosen for this study. I examined the subfossil diatom assemblage in the top twenty centimeters of the surface sediments in each of these four lakes in an attempt to reconstruct their …

The optimal mechanism in differential privacy
… distributions in the optimal mechanism has staircase-shaped probability density functions which are symmetric (around the origin), monotonically decreasing and geometrically decaying. The staircase mechanism can be viewed as a geometric mixture of uniform probability distributions, providing …

Operant Procedures in the Auditory Assessment of "Difficult-To-Test" Individuals
… method and a trials-wise tracking procedure, the staircase method. The order of threshold test administration was counterbalanced across subjects. Findings. Reliable hearing threshold levels were obtained within subjects and within the type of threshold test employed. All subjects were observed to …

Adaptive Slicing in Additive Manufacturing Process using a Modified Boundary Octree Data Structure
… layer-by-layer fabrication of a part leads to a staircase effect affecting its final quality. Parts manufactured using AM process may not satisfy the specified tolerance requirements due to this staircase effect. An improved surface quality (reduction in staircase effect) and a reduced build time …

Development of a layerless additive manufacturing stereolithography machine to improve surface quality and dimensional accuracy
… in a layered build process, which results in the staircase effect: a common problem in layered manufacturing giving a lower quality part surface due to created cusps on the surface. Manufacturing the part using a continuous build should theoretically eliminate this issue. A methodology for the …

Timing of erosional episodes in the Marble Canyon and Vermilion Cliffs region from apatite (U-Th)/He thermochronology
… of the Vermilion Cliffs portion of the Grand Staircase, are examined using a synthesis of new and published low-temperature thermochronology datasets. I test models for a 50-70 Ma Marble Canyon and interpretations that postulate SW to NE progressive denudational stripping of the Colorado …

Perception and Eye Alignment Control: Do People Think the Same Way Their Brain Thinks?
… upper and lower halves of the stereogram. A staircase method was used to find the disparity that produced 75% correct performance in each condition, taken as the mean of the last five staircase trials. Results: Results from 5 subjects show strikingly similar effects for stereoscopic depth and …

A statistical analysis of the fatigue behaviour of single and multi-spot welded joints.

Infinite staircases for Hirzebruch surfaces
This thesis gives a classification of infinite staircases for the ellipsoid embedding functions of Hirzebruch surfaces. The ellipsoid embedding function is a generalization of symplectic ball packing problems. For a symplectic manifold, the function gives the smallest amount of which the symplectic …

Transitions : a sanatorium on the seaside
… In formal terms, the project consists of a staircase which establishes the physical connection between harbour and town. This wound in the wall generates a building, in this case a sanatorium, and a series of tidal pools.
