Theoretical and Experimental Verification of Dynamic Behaviour of a Guided Spline Arbor Circular Saw

open access: yesShock and Vibration, 2017
An analysis of the dynamic and stability characteristics of a guided wood cutting spline arbor circular saw is presented. A multibody dynamic model is developed to consider the idling and cutting characteristics.

Research into the geometry of the delimbing head of cutting knives

open access: yesResearch in Agricultural Engineering, 2013
Limbing with a wedge tool as a chipless operation is accompanied by a large deformation of wood in the cutting plane, i.e. at the spot of contact with the tool face as well as in the zone adjacent to this plane.

Bessel Beam Dielectrics Cutting with Femtosecond Laser in GHz-Burst Mode

open access: yesMicromachines, 2023
We report, for the first time to the best of our knowledge, Bessel beam dielectrics cutting with a femtosecond laser in GHz-burst mode. The non-diffractive beam shaping is based on the use of an axicon and allows for cutting glasses up to 1 mm thickness ...

The Number of Plane Corner Cuts

open access: yesAdvances in Applied Mathematics, 1999
An \(n\)-element subset \(\lambda\) of \(\mathbb{N}^2\) which is cut off a line is called a (plane) corner cut of size \(n\). Let be \({\mathbb{N}^2\choose n}_{ \text{cut}}\) the set of corner cuts of size \(n\). [See \textit{S. Onn} and \textit{B. Sturmfels}, ibid., 29-48 (1999; above).] The authors give a generating for the number \(\#{\mathbb{N}^2 ...

Cutting Planes for Signomial Programming

open access: yesSIAM Journal on Optimization
Cutting planes are of crucial importance when solving nonconvex nonlinear programs to global optimality, for example using the spatial branch-and-bound algorithms. In this paper, we discuss the generation of cutting planes for signomial programming. Many global optimization algorithms lift signomial programs into an extended formulation such that these

Cutting Plane and Frege Proofs

open access: yesInformation and Computation, 1995
The cutting plane refutation system CP for classical propositional calculus [see \textit{W. Cook}, \textit{C. R. Coullard} and \textit{Gy. Turan}, Discrete Appl. Math. 18, 25-38 (1987; Zbl 0625.90056)], initially coming from works in operation research, can be considered as an extension of resolution based on showing the non-existence of solutions for ...

Multiple Cuts in the Analytic Center Cutting Plane Method

open access: yesSIAM Journal on Optimization, 2000
Summary: We analyze the multiple cut generation scheme in the analytic center cutting plane method. We propose an optimal primal and dual updating direction when the cuts are central. The direction is optimal in the sense that it maximizes the product of the new dual slacks and of the new primal variables within the trust regions defined by Dikin's ...

The Analytic Center Cutting Plane Method with Semidefinite Cuts

open access: yesSIAM Journal on Optimization, 2003
Summary: We analyze an analytic center cutting plane algorithm for convex feasibility problems with semidefinite cuts. The problem of interest seeks a feasible point in a bounded convex set, which contains a full-dimensional ball with radius \(\varepsilon
