An Exploration into Measurement Consistency on Coordinate Measuring Machines [PDF]
Procedia CIRP, 2014 In high precision industry, the measurement of geometry is often performed using coordinate measuring machines (CMMs). Measurements on CMMs can occur at many places within a long and global supply chain. In this context it is a challenge to control consistency, so that measurements are applied with appropriate levels of rigour and achieve comparable ...

Quantum Turing Machines: Computations and Measurements [PDF]
Applied Sciences, 2020 Contrary to the classical case, the relation between quantum programming languages and quantum Turing Machines (QTM) has not been fully investigated. In particular, there are features of QTMs that have not been exploited, a notable example being the intrinsic infinite nature of any quantum computation.
