True equivalent chip thickness for tools with a nose radius

A majority of the established systems for choice and optimization of cutting data are based on Woxén’s equivalent chip thickness, heW. In metal cutting theory and models, the equivalent chip thickness is of vital importance when the depth-of-cut ap is in the same order or smaller than the nose radius r. Woxén made considerable simplifications in his chip area model, that form the basis for calcula

PROGRESS OF THE COMMISSIONING OF THE TEST FEL AT MAX-lab

In a collaboration between MAX-lab and BESSY a test facility for Harmonic Generation Free Electron Laser is being constructed at MAX-lab. The setup uses the existing MAX-lab injector together with a Ti:Sa 263 nm laser system, used for both the gun and seeding, and an optical klystron consisting of a modulator, a chicane and a radiator. The different parts of the system have been installed and comm

Meeting the Challenge of Computer Science in the Industrial Applications of Control: An Introductory Discussion to the Special Issue

The motivations, objectives, and results of the project tilted Facing the Challenge of Computer Science in the Industrial Applications of Control, which was launched by the IEEE Control Systems Society and the IFAC Committee on Theory, are presented. Potential alternatives for reducing costs in control industries at those points where they are most significant, control paradigms beyond traditional

Monte Carlo simulations of optical human sinusitis diagnostics

We investigate the feasibility of using diode laser gas spectroscopy for sinusitis diagnostics. We simulate light propagation using the Monte Carlo concept, as implemented by the Advanced Systems Analysis Program (ASAPTM) software. Simulations and experimental data are compared for a model based on two scattering bodies representing human tissue, with an air gap in-between representing the sinus c

States of the Business Concepts Model: Structural Assertions' Impact on Natural Language Business Rules

Organizations constantly need to adapt to the rapidly changing macro environment. Information systems, that hinder and restrain flexibility, may jeopardize the ability for organizations to survive. A new method for developing information systems called the Business Rules Approach has emerged with promises of business agility. The Business Rules Approach focuses on business rules which are reliant
