Self-Referential Noise as a Fundamental Aspect of Reality [PDF]

open access: yes, 1999
Noise is often used in the study of open systems, such as in classical Brownian motion and in Quantum Dynamics, to model the influence of the environment.

Posterior condylar offset changes and its effect on clinical outcomes after posterior-substituting, fixed-bearing total knee arthroplasty: anterior versus posterior referencing

open access: yesKnee Surgery & Related Research, 2020
Background We sought to determine whether there was a difference in the posterior condylar offset (PCO), posterior condylar offset ratio (PCOR) and clinical outcomes following total knee arthroplasty (TKA) with anterior referencing (AR) or posterior ...

Polypolar lemniscate coordinate system [PDF]

open access: yesКомпьютерные исследования и моделирование, 2009
The polypolar coordinate system, as well as classical polar, characterizes a point on a plane by polar radius and polar angle , but utilizes multiple poles instead of one pole. Such referencing can be provided by a class of multifocal lemniscates.

Performance Analysis of a Gravity Gradient Referenced Navigation System

open access: yesJournal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, 2014
As an alternative way to overcome the weakness of the global navigation satellite system (GNSS) in hostile situation, a gravity gradient referenced navigation (GGRN) has been developed. This paper analyzed the performance of GGRN with respect to the initial errors, DB resolution as well as update rates.

Orientation of a Vector Magnetometer Optically Referenced to an External Coordinate System [PDF]

open access: yesIEEE Transactions on Magnetics, 2020
We present a new method to realize a vector magnetometer that has been optically referenced to an external coordinate system. The vector magnetometer is made up of three Hall sensors attached to the orthogonal faces of a glass cube. When placed in a homogeneous magnetic field, rotating the vector magnetometer around two axes allows the orientation of ...
