The relativity of density

Archaeology in Oceania, 1995
AbstractIn an attempt to overcome biases resulting from small sample size, we examine the potential of relative density, which Ambrose (n.d.; 1994) and Green (1987) have proposed is a non‐destructive, inexpensive, and easy technique for characterising the chemical composition of obsidian from the different sources in Melanesia.

Density Is Only Relative

Science, 2005
As a long-time reader of Science , I'm continually struck by the many parallels and cross-connects among articles from diverse disciplines. The 9 Sept. issue was no exception. A few News Focus articles (“Dissecting a hidden breast cancer risk,” J. Couzin, p.

On the relative density of clouds

Quarterly Journal of the Royal Meteorological Society, 2017
A simple analysis of the relative density of clouds with respect to dry and/or moist air is presented using modern and standard definitions. The results are consistent with current knowledge in atmospheric science and offer justification to common inadvertent simplifications used in the scientific literature.

Relative Density Estimation with Censored Data

The Canadian Journal of Statistics / La Revue Canadienne de Statistique, 2000
Summary: Well-described tools for comparing two populations via their cumulative distribution functions \(F\) and \(F_0\) are the so-called relative distribution \(R\left( t\right) =F\left\{ F_0^{-1}\left( t\right) \right\} \) and the corresponding relative density (or grade density) r(t).

Single homopolymers in the relative density representation

Physical Review E, 2001
A single symmetric homopolymer is studied in the grand ensemble of its monomeric units. For an arbitrary external field but next neighbor interactions alone, such a system is represented as a functional of the local density to local fugacity ratio, conjugate to the fugacity, with the excess grand potential as thermodynamic generating function.

The Framework of Relative Density-Based Clustering

2017
Density-based clustering, using two-phase scheme which consists of an online component and an offline component, is an effective framework for data stream clustering, it can find arbitrarily shaped clusters and capture the evolving characteristic of real-time data streams accurately.

The relative strength of K-density

1980
K-density is a property of occurrence nets which can be thought of as mathematical models of processes. We study K-density both formally, as compared with other axioms, and informally, as interpreted and compared with the properties of continuity and computability. We show that, in a certain sense, K-density is an axiom of discreteness.

Statistical Estimation of Relative Density

Journal of Geotechnical Engineering, 1984
A new procedure is proposed to evaluate in situ relative density using SPT values, and to quantify the uncertainty associated with that prediction. The relationship is first developed under laboratory conditions, then corrected for in situ conditions.

Effect of Variations in Minimum Density on Relative Density

2009
THIS PAPER DESCRIBES THE RESULTS OF AN INVESTIGATION CARRIED OUT TO STUDY THE EFFECT OF VARIATIONS IN MINIMUM DENSITY ON RELATIVE DENSITY TEST RESULTS. THE MATERIAL SELECTED FOR THE INVESTIGATION WAS OBTAINED DURING CONSTRUCTION OF KETTLE GENERATING STATION. THE TEST RESULTS WERE STATISTICALLY ANALYSED.
