An investigation on the mechanics of nanometric cutting and the development of its test-bed [PDF]

open access: yes, 2003
The mechanics of machining at a very small depth of cut (100 nm or less) is not well understood. The chip formation physics, cutting forces generation, resulting temperatures and the size effects significantly affect the efficiency of the process and ...

Simulation of a finishing operation : milling of a turbine blade and influence of damping [PDF]

open access: yes, 2012
Milling is used to create very complex geometries and thin parts, such as turbine blades. Irreversible geometric defects may appear during finishing operations when a high surface quality is expected.

Mechanical properties and thermal behaviour of two-stage concrete containing palm oil fuel ash [PDF]

open access: yes, 2017
Two-stage concrete (TSC) is a special type of concrete which is made by placing coarse aggregate in a formwork and injecting a grout either by pump or under the gravity force to fill the voids. Over the decades, the application of supplementary cementing

Simulating Turing machines on Maurer machines

open access: yesJournal of Applied Logic, 2008
This paper presents three ways to simulate Turing machines on Maurer machines, which give insight into the connections between Turing machines, Maurer machines and real computers: 1. The Maurer machine on which Turing machines are simulated has the most obvious operations for simulation of Turing machine. Unlike real computers, the Maurer machine, used
