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, 2004
This 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, 2014
The 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 magnetic resonance imaging of the mandibular nerve

Dentomaxillofacial Radiology, 2005
Magnetic 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
