Molecular dynamics simulations of nanometric cutting on monocrystalline germanium are conducted to investigate the subsurface deformation during and after nanometric cutting. The continuous random network model of amorphous germanium is established by molecular dynamics simulation, and its characteristic parameters are extracted to compare with those of the machined deformed layer. The coordina...

The present work proposes new heuristics and algorithms for the 3D Cutting and Packing class of problems. Specifically the cutting stock problem and a real-world application from the retail steel distribution industry are addressed. The problem being addressed for the retail steel distribution industry is the retail steel cutting problem, which is how to cut steel in order to satisfy the custom...

Electrochemical cutting using tube electrode with inclined holes is a machining method that directly and obliquely injects electrolyte into the gap through jet-flow on sidewall of electrode, allowing electrochemical workpiece. To improve efficiency accuracy this technique, workpiece vibration in feed direction–assisted proposed which rapidly periodically changes gap. The near-instantaneous incr...

the investigation was conducted on wet and dry seasons of ethiopia during the year 2012/2013 at wondo genet agricultural research center nursery site. four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...

In 1978, James Cutting published an algorithm to generate point-light displays that resemble the movements of the joints of a human walker. The method has since been used frequently to create stimuli for research on biological motion perception. More recently, Troje and Westhoff (2006) found that pattern of local movement of the feet was used to derive the direction in which a pointlight walker...

IF a corneal graft is not properly coapted to its bed, a series of complications may ensue. These have been summarized by Barraquer (1950). A cause of this lack of coaptation is that the sides of the graft or of the bed may not be vertical, and that if sloping they may not slope in similar directions. A series of simple tests were therefore carried out to determine: (a) The direction of the sid...

The material detachment mechanisms of ductile metal surfaces are studied experimentally during dry grinding operation in a simulated experiment with near single grit contact with the surface. The spectra of the cutting and thrust forces are recorded and analyzed. It is found that the thrust force changes its direction from a compressive to a tensile mode. The ratio between the thrust and cuttin...
