Geometric Accuracy of Machine Tools
2018Geometric accuracy belongs to one of the main parameters of the machine tool. It serves not only for the purpose of machine delivery to the customer or for demonstration of proper service intervention but also for assessment of improvements compared to the current state. The information on geometric accuracy of the machine is also used as a feedback to

The accuracy of geometric channel modeling methods
Fourth International Conference on Information, Communications and Signal Processing, 2003 and the Fourth Pacific Rim Conference on Multimedia. Proceedings of the 2003 Joint, 2004This paper addresses the subject which is too often overlooked in the analysis of a geometric model for wireless channel - the axioms corresponding to a priori properties of the channel that is modeled using geometric approach must represent realistic wave propagation.

Geometric accuracy of CNC machine tools
Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014, 2014The present article is dedicated to the identification and interpretation of geometric errors of CNC machine tools. Identification of geometric errors plays a large role in the construction of the so-called “Error maps”. These maps can be used to describe the behaviour of the machine in the workspace without load or under conditions of finishing ...

Geometric accuracy of the NewTom 9000 Cone Beam CT
Dentomaxillofacial Radiology, 2005To determine the geometric accuracy of digital volume tomograms to assess their usability for implant planning.A measuring object with 216 measuring points, whose geometry is exactly known, is X-rayed with a NewTom 9000 cone beam scanner; thereafter the geometry of the volume tomogram of the object is compared with the original body.Considering all ...

Geometric accuracy of magnetic resonance imaging of the mandibular nerve
Dentomaxillofacial Radiology, 2005Magnetic resonance imaging (MRI) is not routinely used for dental implant planning. A prerequisite for dental implant planning is the accurate imaging of risk structures like the mandibular nerve. The geometric accuracy of the imaging of the mandibular nerve was investigated.Two human cadaver heads were scanned using MRI. Computed tomography (CT) scans
