Their main disadvantage is the distortion of the flow itself by the structure supporting the transducers, which requires a correction based upon wind tunnel measurements to minimize the effect.

The internal level, which is hidden inside the DBMS and depends on its implementation ( see Implementation section below ), requires a different level of detail and uses its own data structure types, typically different in nature from the structures of the external and conceptual levels which are exposed to DBMS users ( e. g., the data models above ): While the external and conceptual levels are focused on and serve DBMS users, the concern of the internal level is effective implementation details.

The implementation of a data structure usually requires writing a set of procedures that create and manipulate instances of that structure.

This procedure requires the firing of a series of charges of the same density and physical structure, but different diameters, and the extrapolation of the resulting detonation velocities to predict the detonation velocity of a charge of infinite diameter.

The development is taking place on an internet-based workspace, called iCAT ( Collaborative Authoring Tool ) Platform, somewhat similar to Wikipedia – yet it requires more structure and peer review process.

This is always CV ( consonant onset with vowel nucleus ), such as ka, ki, etc., or V ( vowel ), such as a, i, etc., with the sole exception of the C grapheme for nasal codas usually romanised as n. This structure had some scholars label the system moraic instead of syllabic, because it requires the combination of two syllabograms to represent a CVC syllable with coda ( i. e. CVn, CVm, CVng ), a CVV syllable with complex nucleus ( i. e. multiple or expressively long vowels ), or a CCV syllable with complex onset ( i. e. including a glide, CyV, CwV ).

It is also said that a synthase is a lyase ( a lyase is an enzyme that catalyzes the breaking of various chemical bonds by means other than hydrolysis and oxidation, often forming a new double bond or a new ring structure ) and does not require any energy, whereas a synthetase is a ligase ( a ligase is an enzyme that binds two chemicals or compounds ) and thus requires energy.

This requires a naming structure for LDAP entries so one can find a server holding a given DN or distinguished name, a concept defined in the X. 500 Directory and also used in LDAP.

In phyllosilicates, a sheet structure is formed which requires three shared oxygens ; in the case of double-chain silicates, some tetrahedra must share two corners instead of three as otherwise a sheet structure would result.

In contrast to the more strict definition proposed by IUPAC, which requires a d-block metal and a sandwich structure, the term metallocene and thus the denotation-ocene, is applied in the chemical literature also to non-transition metal compounds, such as Cp < sub > 2 </ sub > Ba, or structures where the aromatic rings are not co-planar, such as found in manganocene or titanocene dichloride ( Cp < sub > 2 </ sub > TiCl < sub > 2 </ sub >).

Identifying mushrooms requires a basic understanding of their macroscopic structure.

Identification to species, however, requires more effort ; one must remember that a mushroom develops from a button stage into a mature structure, and only the latter can provide certain characteristics needed for the identification of the species.

This idea requires the building of a molecular structure that will permit control and detection of nerve impulses by an external computer.

Knowledge of the proteome requires knowledge of ( 1 ) the structure of the proteins in the proteome and ( 2 ) the functional interaction between the proteins.

However, proteins can become cross-linked, most commonly by disulfide bonds, and the primary structure also requires specifying the cross-linking atoms, e. g., specifying the cysteines involved in the protein's disulfide bonds.

The functional form of single-stranded RNA molecules, just like proteins, frequently requires a specific tertiary structure.

Inherent to any serialization scheme is that, because the encoding of the data is by definition serial, extracting one part of the serialized data structure requires that the entire object be read from start to end, and reconstructed.

Although crystallography can be used to characterize the disorder in an impure or irregular crystal, crystallography generally requires a pure crystal of high regularity to solve the structure of a complicated arrangement of atoms.

: The module structure requires more explanation:

This requires a programming language capable of reflection, the ability to observe and modify its own structure and behaviour.

This structure requires four long and large poles ( these should all be nearly equal in length ), and 4-16 medium-sized poles.

Starting from finite-dimensional vector spaces ( as objects ) and the dual functor, one can define a natural isomorphism, but this requires first adding additional structure, then restricting the maps from " all linear maps " to " linear maps that respect this structure ".

The deepest hole drilled to date is the SG-3 borehole which is deep, part of the Soviet Kola Superdeep Borehole project ; thus, visual knowledge of the Earth's structure extends that far.

The structure itself is formed by superwinds from the black hole.

One method of testing a structure for carbonatation is to drill a fresh hole in the surface and then treat the cut surface with phenolphthalein indicator solution.

The removal of an electron in this way renders the electronic structure of the atom unstable, and electrons in higher orbitals " fall " into the lower orbital to fill the hole left behind.

The bait is then secured to a tree or secure structure in an area which is known to be frequented by lions ; usually this will be close to a watering hole.

It is a circular structure with a hole in the 12 m-diameter dome.

Some of the amenities include a 9 hole golf course, play structure, picnic shelters, restrooms, and beach style swimming.

In reality, due to the crystal structure properties, the hole is not localized to a single position as described in the previous example.

This device used a novel two-layer structure with separate hole transporting and electron transporting layers such that recombination and light emission occurred in the middle of the organic layer.

A diagram of the structure of the Kruskal – Szekeres coordinates # The maximally extended Schwarzschild solution | maximally extended black hole spacetime.

Babinet's Principle states ( in optics ) that when a field behind a screen with an opening is added to the field of a complementary structure ( that is a shape covering the screen hole ), then the sum is equal to the field where there is no screen.

Within the structure a " spider hole " entrance, camouflaged with bricks and dirt was located.

The nest is a bulky, often domed structure, with a small hole towards the top.

That implies the breakdown of parametrization of points ; it is prominent in general relativity, where a gravitational singularity, at which the gravitational field is strong enough to change the very structure of space-time, is identified with a black hole.

Rain and surface water flowing into a low-lying open pit will also lead to soil erosion around the edges of the pit that may eventually undermine the building foundation, and potentially lead to collapse of the structure into the enlarging hole.

In a medieval castle or other building, a garderobe was usually a simple hole discharging to the outside into a cesspit or the moat, depending on the structure of the building.

A Denehole ( alternatively Dene hole or Dene-hole ) is an underground structure consisting of a number of small chalk caves entered by a vertical shaft.

John Rossman, ATP Semester Grant to attend a research meeting with Dr. Arlie Petters of Duke University in Spring 2009, " Examination of the Kerr black hole structure -- implications for wave-fronts.

For example, the potential profile across the quantum well structure of a diode laser can be mapped and analyzed ; such a profile could indicate the electron and hole distributions where light is generated and could lead to improved laser designs.

In 1960, Kruskal discovered the full classical spacetime structure of the simplest type of black hole in General Relativity.

The inner structure of an Active Galaxy showing the accretion disk and relativistic jets in the vicinity of a supermassive black hole.

Over a cross-shaped hole in the ground previously designated as a last-ditch defensive area near the center of the fort, the army built the extant citadel structure to house the commandant in 1796.

) inside the brain, at the calculated coordinates for the desired structure, through a small trephined hole in the skull.

In other cases, when the pit becomes too full, it may be emptied or the hole made be covered with soil and the associated structure moved or rebuilt over a new pit.
