NanoTags for Improved Cuttings Depth Correlation
Petrophysics – The SPWLA Journal of Formation Evaluation and Reservoir Description, 2021During a drilling operation, rock cuttings are often sampled off a shale shaker for lithology and petrophysical characterization. These analyses play an important role in describing the subsurface, and it is important that the depth origin of the cuttings be accurately determined.

Intermittent metal cutting at small cutting depths—2. Cutting forces
International Journal of Machine Tools and Manufacture, 1988Abstract Cutting forces in intermittent metal cutting at small cutting depths were investigated by single edge experiments. Single cutting strokes were performed in a modified Charpy pendulum tester which offers cutting and thrust force measurement and accurate selection of cutting speed and feed in ranges typical for many intermittent high speed ...

Reserch on Cutting Depth Effect in Cutting Process
Applied Mechanics and Materials, 2011In the cutting procedure, the cutting depth influences cutting forces, chip breaking, chip shaping, and the distribution status of residual stress. The two-dimension heat-mechanic coupling orthogonal cutting model is established with the FEM analysis software by use of the Lagrange quality point coordinate system description method in this paper.

Multi-cut light field depth estimation
2015 3rd IAPR Asian Conference on Pattern Recognition (ACPR), 2015We investigate the problem of depth map estimation of a scene from 4D light-field data. Unlike prior work, we process all the input images (or sub-images) of the light-field. Indeed, for each point of the scene, different depth candidates are estimated by considering all possible 3D light-field cuts instead of only 2, i.e.

The Depth of Cut in Drilling Mode of Rock Cutting
Applied Mechanics and Materials, 2017Drilling and lateral cutting are two cutting modes used by roadheaders in rock cutting. Accurate estimation of the depth of cut (DOC) of the cutterhead of a roadheader is critical for improving the performance and reliabilityofthe roadheader. Some models have been developed for calculating the DOC of a cutterhead in lateral cutting mode.

In this chapter we first introduce a standard cut-elimination procedure for the first-order logic and the \(\omega \)-logic, by which we see that the tree-height of the resulting cut-free proofs is bounded by a tower of exponential functions. Such a control of the tree-heights in cut-elimination is one of the most important results in ordinal analysis.

Segmentation of depth image using graph cut
2012 9th International Conference on Fuzzy Systems and Knowledge Discovery, 2012A large number of tasks in computer vision involve finding a target from a background image. It is also known as the foreground/background discrimination problem. Various methods have been developed to solve this problem. [1, 2, 10, 11, 12] Newly developed techniques for general purpose of object abstraction use both color and edge information for ...

Multi-label Depth Estimation for Graph Cuts Stereo Problems
Journal of Mathematical Imaging and Vision, 2010We describe here a method to compute the depth of a scene from a set of at least two images taken at known view-points. Our approach is based on an energy formulation of the 3D reconstruction problem which we minimize using a graph-cut approach that computes a local minimum whose energy is comparable (modulo a multiple constant) with the energy of the ...
