Smaller circles bend more sharply, and hence have higher curvature. The curvature of a smooth curve is defined as the curvature of its osculating circle at each point. The osculating circle of a sufficiently smooth plane curve at a given point on the curve is the circle whose center lies on the inner normal line and whose curvature is the same as that of the given curve at that point. This circle is tangent to the curve at the given point.&#xD;
&#xD;
That is, given a point P on a smooth curve C, the curvature of C at P is defined to be 1/R where R is the radius of the osculating circle of C at P. The magnitude of curvature at points on physical curves can be measured in diopters (also spelled dioptre) — this is the convention in optics. [Wikipedia]</qudt:description>

    <dc:description rdf:datatype="http://www.w3.org/2001/XMLSchema#string">In physics, natural units are physical units of measurement based only on universal physical constants. For example the elementary charge e is a natural unit of electric charge, or the speed of light c is a natural unit of speed. A purely natural system of units is defined in such a way that some set of selected universal physical constants are normalized to unity; that is, their numerical values in terms of these units become exactly 1. Examples are Planck Units and Atomic Units. Atomic units (au or a.u.) form a system of natural units which is especially convenient for atomic physics calculations. There are two different kinds of atomic units, which one might name Hartree atomic units[1] and Rydberg atomic units, which differ in the choice of the unit of mass and charge. Planck units are unique among systems of natural units, because they are not defined in terms of properties of any prototype, physical object, or even elementary particle.

  <rdf:Description rdf:about="#VolumeThermalExpansionUnit">
    <qudt:description rdf:datatype="http://www.w3.org/2001/XMLSchema#string">When the temperature of a substance changes, the energy that is stored in the intermolecular bonds between atoms changes. When the stored energy increases, so does the length of the molecular bonds. As a result, solids typically expand in response to heating and contract on cooling; this dimensional response to temperature change is expressed by its coefficient of thermal expansion.&#xD;
&#xD;
Different coefficients of thermal expansion can be defined for a substance depending on whether the expansion is measured by:&#xD;
&#xD;
    * linear thermal expansion&#xD;
    * area thermal expansion&#xD;
    * volumetric thermal expansion&#xD;
&#xD;
These characteristics are closely related. The volumetric thermal expansion coefficient can be defined for both liquids and solids. The linear thermal expansion can only be defined for solids, and is common in engineering applications.&#xD;
&#xD;
Some substances expand when cooled, such as freezing water, so they have negative thermal expansion coefficients. &#xD;
&#xD;
For exactly isotropic materials, the volumetric thermal expansion coefficient is very closely approximated as three times the linear coefficient. [Wikipedia]</qudt:description>

For example, the meter is a quantity of length that has been rigorously defined and standardized by the BIPM (International Board of Weights and Measures). Any measurement of the length can be expressed as a number multiplied by the unit meter. More formally, the value of a physical quantity Q with respect to a unit (U) is expressed as the scalar multiple of a real number (n) and U, as  Q = nU.</dc:description>

    <qudt:description rdf:datatype="http://www.w3.org/2001/XMLSchema#string">When the temperature of a substance changes, the energy that is stored in the intermolecular bonds between atoms changes. When the stored energy increases, so does the length of the molecular bonds. As a result, solids typically expand in response to heating and contract on cooling; this dimensional response to temperature change is expressed by its coefficient of thermal expansion.&#xD;
&#xD;
Different coefficients of thermal expansion can be defined for a substance depending on whether the expansion is measured by:&#xD;
&#xD;
    * linear thermal expansion&#xD;
    * area thermal expansion&#xD;
    * volumetric thermal expansion&#xD;
&#xD;
These characteristics are closely related. The volumetric thermal expansion coefficient can be defined for both liquids and solids. The linear thermal expansion can only be defined for solids, and is common in engineering applications.&#xD;
&#xD;
Some substances expand when cooled, such as freezing water, so they have negative thermal expansion coefficients.&#xD;
&#xD;
For exactly isotropic materials, the area thermal expansion coefficient is very closely approximated as twice the linear coefficient.</qudt:description>

    <qudt:description rdf:datatype="http://www.w3.org/2001/XMLSchema#string">When the temperature of a substance changes, the energy that is stored in the intermolecular bonds between atoms changes. When the stored energy increases, so does the length of the molecular bonds. As a result, solids typically expand in response to heating and contract on cooling; this dimensional response to temperature change is expressed by its coefficient of thermal expansion.&#xD;
&#xD;
Different coefficients of thermal expansion can be defined for a substance depending on whether the expansion is measured by:&#xD;
&#xD;
    * linear thermal expansion&#xD;
    * area thermal expansion&#xD;
    * volumetric thermal expansion&#xD;
&#xD;
These characteristics are closely related. The volumetric thermal expansion coefficient can be defined for both liquids and solids. The linear thermal expansion can only be defined for solids, and is common in engineering applications.&#xD;
&#xD;
Some substances expand when cooled, such as freezing water, so they have negative thermal expansion coefficients. [Wikipedia]</qudt:description>

  <rdf:Description rdf:about="#LinearThermalExpansionUnit">
    <qudt:description rdf:datatype="http://www.w3.org/2001/XMLSchema#string">When the temperature of a substance changes, the energy that is stored in the intermolecular bonds between atoms changes. When the stored energy increases, so does the length of the molecular bonds. As a result, solids typically expand in response to heating and contract on cooling; this dimensional response to temperature change is expressed by its coefficient of thermal expansion.&#xD;
&#xD;
Different coefficients of thermal expansion can be defined for a substance depending on whether the expansion is measured by:&#xD;
&#xD;
    * linear thermal expansion&#xD;
    * area thermal expansion&#xD;
    * volumetric thermal expansion&#xD;
&#xD;
These characteristics are closely related. The volumetric thermal expansion coefficient can be defined for both liquids and solids. The linear thermal expansion can only be defined for solids, and is common in engineering applications.&#xD;
&#xD;
Some substances expand when cooled, such as freezing water, so they have negative thermal expansion coefficients. [Wikipedia]</qudt:description>

    <vaem:description rdf:datatype="http://www.w3.org/2001/XMLSchema#string">The QUDT, or 'Quantity, Unit, Dimension and Type' collection of ontologies define the base classes properties, and restrictions used for modeling physical quantities, units of measure, and their dimensions in various measurement systems. The goal of the QUDT ontology is to provide a unified model of, measurable quantities, units for measuring different kinds of quantities, the numerical values of quantities in different units of measure and the data structures and data types used to store and manipulate these objects in software. This OWL schema is a foundation for a basic treatment of units.</vaem:description>
