Aggregation-based cutting-planes for packing and covering integer programs [PDF]

open access: yesMathematical programming, 2016
In this paper, we study the strength of Chvátal–Gomory (CG) cuts and more generally aggregation cuts for packing and covering integer programs (IPs). Aggregation cuts are obtained as follows: given an IP formulation, we first generate a single implied ...

An Innovative Experimental Study of Corner Radius Effect on Cutting Forces [PDF]

open access: yes, 2014
The cutting forces are often modelled using edge discretisation methodology. In finish turning, due to the smaller corner radii, the use of a local cutting force model identified from orthogonal cutting tests poses a significant challenge. In this paper,

Modelling of cutting fibrous composite materials: current practice [PDF]

open access: yes, 2015
Using fibre reinforced polymers (FRP) is increasing across many industries. Although FRP are laid-up in the near-net shape, several cutting operations are necessary to meet quality and dimensional requirements.

Cutting rectangles in the plane

open access: yesDiscrete Mathematics, 1982
AbstractLet F be a planar family of pairwise disjoint translates of a parallelogram. It is shown that if every four members of F are intersected by some straight line, then there is a straight line which intersects all but at most two members of F. If it is instead assumed that every two members of F are intersected by some line that is parallel to one

Crystal Orientation Effect on the Subsurface Deformation of Monocrystalline Germanium in Nanometric Cutting

open access: yesNanoscale Research Letters, 2017
Molecular dynamics simulations of nanometric cutting on monocrystalline germanium are conducted to investigate the subsurface deformation during and after nanometric cutting.

Experimental investigation of hydrodynamics of melt layer during laser cutting of steel [PDF]

open access: yes, 2011
In laser cutting process, understanding of hydrodynamics of melt layer is significant, because it is an important factor which controls the final quality. In this work, we observed hydrodynamics of melt layer on kerf front in the case of laser cutting of

Local and global lifted cover inequalities for the multidimensional knapsack problem [PDF]

open access: yes, 2008
The 0-1 Multidimensional Knapsack Problem (0-1 MKP) is a well-known (and strongly NP-hard) combinatorial optimization problem with many applications. Up to now, the majority of upper bounding techniques for the 0-1 MKP have been based on Lagrangian or ...

Depth lower bounds in Stabbing Planes for combinatorial principles [PDF]

open access: yesLogical Methods in Computer Science
Stabbing Planes (also known as Branch and Cut) is a proof system introduced very recently which, informally speaking, extends the DPLL method by branching on integer linear inequalities instead of single variables.
