TransCut: Interactive Rendering of Translucent Cutouts
IEEE Transactions on Visualization and Computer Graphics, 2013We present TransCut, a technique for interactive rendering of translucent objects undergoing fracturing and cutting operations. As the object is fractured or cut open, the user can directly examine and intuitively understand the complex translucent interior, as well as edit material properties through painting on cross sections and recombining the ...

Numerical Study of Twisted Tape with Circular Cutout and Triangular Cutout in a Circular Tube
2021Every industry has one common instrument that is heat exchanger. From a bike to a solar desalination plant that is spread in acres, heat exchangers are regular signtings. But sometimes they lack in their performance, to overcome which many accessories are used. Diverse method to improve the thermophysical performances is twisted wires and twisted tapes.

Buckling of cylinders with cutouts
AIAA Journal, 1970A numerical solution is presented for the problem of stability of elastic cylindrical shells with rectangular cutouts. Reinforcements around the cutouts and other discrete stiffening elements are considered and the loading can be either axial or lateral.

Shells of Revolution with Cutouts
Journal of the Structural Division, 1979A procedure for analyzing shells of revolution with nonaxisymmetric geometrical or physical occurrences, e.g., cutouts, is outlined. This means, of course, that the shell is not actually a shell of revolution. The goal is to take advantage of the efficient tools, e.g., numerical integration, available for analyzing shells of revolution to find the ...

Discontinuity-aware video object cutout
ACM Transactions on Graphics, 2012Existing video object cutout systems can only deal with limited cases. They usually require detailed user interactions to segment real-life videos, which often suffer from both inseparable statistics (similar appearance between foreground and background) and temporal discontinuities (e.g. large movements, newly-exposed regions following disocclusion or

Precise object cutout from images
Proceedings of the 16th ACM international conference on Multimedia, 2008In this paper we propose a novel approach to the problem of interactive foreground/background segmentation in images. With user provided strokes which indicate foreground and background seeds, we estimate two Gaussian mixture models, one for foreground and the other for background, and define two quantities to measure the initial probabilities of each ...

Boundary snapping for robust image cutouts
2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008Boundary snapping is an interactive image cutout algorithm that requires a small number of user supplied control points, or landmarks, to infer the cutout contour. The key idea is to match the appearance of all points along the desired contour to the landmark points, where appearance is given by an intensity profile perpendicular to the boundary.

An Aircraft Differential-Voltage Cutout
Transactions of the American Institute of Electrical Engineers, 1944Experience obtained with present multiengine aircraft electrical systems indicates a need for preventing interchange of current between generators when the system is operating at light loads. Such current interchange causes reverse-current cutouts of conventional design to connect and disconnect their respective generators to the system so rapidly that

On the Plastic Strains in Slabs With Cutouts
Journal of Applied Mechanics, 1953Abstract The complete elastic-plastic problem is set up for a circular slab with a central circular cutout, subjected to uniform external tension. The analysis is carried out under the assumption of generalized plane stress but with possibly finite deformations. The material is assumed to be isotropic, homogeneous, and incompressible, to
