RELATIVE GRAVITY MEASUREMENTS USING PRECISION PENDULUM EQUIPMENT

GEOPHYSICS, 1940
The precision with which relative‐gravity values may be obtained by the use of suitable pendulum equipment is illustrated by actual data obtained in establishing calibration stations used to facilitate the calibration of gravimeters. A résumé of the operating technique, together with the salient features of the Gulf pendulum equipment is given in ...

Precision engineering and Einstein: The Relativity Gyroscope experiment

Precision Engineering, 1979
Abstract One hundred years after Einstein's birth and sixty-four years after the publication of his theory of gravity, General Relativity remains one of the least tested of physical theories. This paper outlines the status of Einstein's tests and goes on to describe a new test, the Relativity Gyroscope experiment, made possible by two relatively new ...

A liquid-filled ionization chamber for high precision relative dosimetry

Physica Medica, 2011
Radiosurgery and intensity modulated radiation therapy (IMRT) treatments are based on the delivery of narrow and/or irregularly shaped megavoltage photon beams. This kind of beams present both lack of charged particle equilibrium and steep dose gradients.

A Study of the Relative Precision of Acupoint Location Methods

The Journal of Alternative and Complementary Medicine, 2002
This study examined the relative precision of four methods of acupoint location: two traditional methods (directional and proportional) and two contemporary methods (elastic and ruler).Seventy-two (72) subjects attempted to locate a fictitious acupoint (FP) with repeated attempts and the resulting coordinates were recorded.The research was carried out ...

High Precision Relative Localization Using a Single Camera

Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007
In this paper a method for high precision relative localization using a single camera is proposed. The method provides pose estimates comparable in resolution to wheel odometry, but being independent of the kinematics and based on an exteroceptive sensor, is resistant to wheel slippage.

Relative precision in the inductive assertion method

1997
The inductive assertion method of Floyd is here applied to programs involving floating point numbers, using a new verification condition generator for C programs known as ProveIt. The exit assertions of such programs need to state that the answers are correct to within some tolerance.

Relatively simple, precise methods to analyze temperature transients in ectotherms

Journal of Thermal Biology, 2001
Relatively complex core-shell models have been used to precisely characterize times and temperatures for ectotherms. There is a simpler method using a second-order analysis of heat flux. We derive the method from an equivalent mechanical system, correct some previously published inaccuracies, and show how to use the method by analyzing thermal ...

Precise relative motions of formation flying space vehicles

AIAA/AAS Astrodynamics Specialist Conference and Exhibit, 1998
This paper presents an analysis of the relative motions between formation flying space vehicles in orbit about the Earth and Mars. Formation flying is proposed for: cross calibration of science instruments on follow-on missions and new technology demonstrations, moving from large platforms to several smaller vehicles with distributed instrumentation ...

Relative precision of linkage mapping in recombinant diploid populations

Canadian Journal of Plant Science, 2007
With the increased effort in mapping linked loci, it is important to understand how the precision of the estimate of linkage intensity is influenced by the level of inbreeding and the sample size. For discreet traits, such as molecular markers, the standard error of linkage intensity has been determined for an F2 and backcross population. However, the
