SPATIAL KINEMATICS OF GEARS IN ABSOLUTE COORDINATES
"... In this article the description of some types of spatial gear constraints (spur gears, bevel gears, etc.) in absolute coordinates is considered. Instead of the numerical expensive calculation of constraint Jacobian matrix we propose to use the transformed Jacobian matrix, which can be calculated muc ..."

Component mode synthesis for multibody systems with absolute coordinates
"... Abstract—In the present paper, the concept of the float-ing frame of reference is transformed to a description based on absolute coordinates. The equations are linearized for a certain configuration of the body based on a corotational strain tensor. Because of the transformation to absolute coordina ..."

THE ABSOLUTE COORDINATE FORMULATION WITH REDUCED STRAIN AND STIFFENING
"... Summary The present work contributes to the field of multibody systems with respect to the absolute coordinate formulation (ACF) with a reduced expression of the strain energy. The ACF is known to be advantageous with respect to the description of constraint equations and the constant mass matrix. A ..."

Predicting Internet Network Distance with Coordinates-Based Approaches
- In INFOCOM
, 2001
"... In this paper, we propose to use coordinates-based mechanisms in a peer-to-peer architecture to predict Internet network distance (i.e. round-trip propagation and transmission delay) . We study two mechanisms. The first is a previously proposed scheme, called the triangulated heuristic, which is bas ..."

is based on relative coordinates that are simply the distances from a host to some special network nodes. We propose the second mechanism, called Global Network Positioning (GNP), which is based on absolute coordinates computed from modeling the Internet as a geometric space. Since end hosts maintain
Closed-form solution of absolute orientation using unit quaternions
- J. Opt. Soc. Am. A
, 1987
"... Finding the relationship between two coordinate systems using pairs of measurements of the coordinates of a number of points in both systems is a classic photogrammetric task. It finds applications in stereophotogrammetry and in robotics. I present here a closed-form solution to the least-squares pr ..."

Contextual versus absolute coordination -- Step one
, 2001
"... An agent who is interested in reading [Ago01a] may also be asked for looking at alternative paradigms of cooperation but "contextual coordination" of [Ago01a, Sec. 3]. We do it in this paper by introducing some paradigms of "absolute," model-theoretic coordination. We argue by us ..."

Gamma Correction and Absolute Coordinate Residual Compensation for Triangular Patterns Phase Shifting Profilometry
"... Triangular patterns phase shifting profilometry is a method of structured light whose three-dimensional reconstructions are susceptible to error from gamma distortion. In practice, the luminance nonlinearity caused by the gamma distortion effect of a digital projector and a digital camera yields und ..."

the measurement error caused by the gamma distortion. By applying an appropriate pre-coding value to the projected patterns, the gamma distortion effect is attenuated and the accuracy is enhanced. The linear least square is compensated the absolute coordinate residuals still existing after gamma correction
Application Research of GRP3000 Absolute Coordinates Track Survey System on Trackworks Construction
"... Recently for the construction and survey of trackworks construction, by using the survey instruments, like theodolite and/or hand tools are still the traditional way. For the setting of track center and rail elevation are still mainly by the theodolite and the level, and then with different instrume ..."

Recently the accuracy of trackworks pavement works had been more stringent than ever before

Meridian: A Lightweight Network Location Service without Virtual Coordinates
- In SIGCOMM
, 2005
"... This paper introduces a lightweight, scalable and accurate framework, called Meridian, for performing node selection based on network location. The framework consists of an overlay network structured around multi-resolution rings, query routing with direct measurements, and gossip protocols for diss ..."

for dissemination. We show how this framework can be used to address three commonly encountered problems, namely, closest node discovery, central leader election, and locating nodes that satisfy target latency constraints in large-scale distributed systems without having to compute absolute coordinates. We show
