Cross section The purpose of the cross section is to determine which horizon can serve as the datum. Because it is shown as horizontal, the thickness variations of the units directly above and below the datum are most simply interpretable on the cross section.

Cross-bedding Tabular cross-bedding, or planar bedding consists of cross-bedded units that are large horizontal wise with reverence to set thickness and that have essentially planar bounding surfaces. Trough cross-bedding, on the other hand, consists of cross-bedding units in which the bounding surfaces are bowed.

- The following formula determines the minimum cross-sectional area of a conductor. This area should be increased by five percent for each additional conductor laminated into the bus structure. This extra five percent is a safety factor compensating for the compounding heat gain within the conductors.

Cross Section Cross Section of a Cone. The cross section is the shape obtained by a cut through a solid perpendicular to the length. A cone is pyramid with a circular cross section. The double cone is a quadratic surface and each single cone is called a nappe. The cross section of a conic section depending upon the relationship between the plane and the slant surface of the cone, the section may be a circle, a parabola, an ellipse or a hyperbola.

- and can study the variations in the patterns of growth, while repeated cross-sectional studies can only look at the growth of the average (which may or may not be the same as the average growth) or other summary statistics, and the growth measured is confounded with other uncontrolled

Film Thickness Film thickness is the depth of the coating applied. Film thickness can be broadly classified as:Wet film thickness - Wet film thickness (WFT) is the thickness of wet paint or any coating film that is liquid-based. Wet thickness is at its peak right after the application of the coating.

What is difference between cross-sectional data and panel data? Popular Answers. I'd add that there is also a type of data that's in between cross-sectional data and panel data. It is typically called repeated cross-sections or pooled cross-sections. For example, annual labour force surveys are repeated cross-sections, because every year, a new random sample is taken from the population.

- Equations [1] and [2] allow interconversion of estimated drying times between round and square cross sections when one or the other is known, thus eliminating the need to obtain experimental data for both cross-sectional configurations.

Surety Bonds Frequently Asked Questions Premiums for surety bonds are more like service charges; the principal is still responsible for paying the full amount of the claim as well as the bond premium. For more information on the topic, read our section titled “ Surety Bonds vs Insurance “.

- The chart below outlines two basic physical properties of metals and non-metals. Metalloids share some of the physical properties of both, so a third property will be used to tell metalloids apart from metals and non-metals.

- Cross-sectional area and the length determine bus bar conductor size. Cross-sectional area (..4) is equal to conductor thickness (t) multiplied by conductor width (w). A value of approximately 400 circular mils per ampere is a traditional basis for design of single conductors.

Thickness Measured in Many Ways The magnetic technique is used to nondestructively measure the thickness of nonmagnetic coatings on ferrous substrates. Most coatings on steel and iron are measured this way. Gages use one of two principles of operation: magnetic pull-off or magnetic and electromagnetic induction. • Magnetic pull-off.

Cross-Sectional Research Method: How Does It Work? This type of research differs from longitudinal studies in that cross-sectional studies are designed to look at a variable at a particular point in time. Longitudinal studies involve taking multiple measures over an extended period while cross-sectional research focuses on looking at variables at a given point in time.
