The traditional instrument was visually modeled on the French horn and has a rear facing bell.

The marching mellophone is used in place of the horn for marching because it is a bell-front instrument allowing projection of the sound in the direction that the player is facing.

Runway 14, facing southeast, has an instrument approach based on the VOR / DME located at the airport.

The instrument is laid across the laps of two facing individuals ( the eponymous " courting " pair ) and used to play duets.

Inside, a new flat instrument panel ( shared with LeSabre, Estate Wagon and Riviera ) with horizontal sweep speedometer ( silver facing with black lettering ) replaced the wrap-around cockpit dash of previous years and door panel trim was revised.

Inside, a new instrument panel continued the wraparound cockpit theme of previous models with new African Crossfire Mahogany facing on the dashboard, console and door panels, which was " real " wood in contrast with the simulated woodgrain material found in most car interiors during that time.

The basic R3 was very basic, with painted bumpers and grill on the outside, the simplest possible instrument pod facing the driver along with a single sun visor, no windshield washer, and on the interior, no door panels.

From its beginning as an instrument held vertically between one's knees with both palms facing down, Hermenge ( in his serpent method-Paris, 1817 ) suggested a horizontal playing position that rested in the right hand palm faced upward.

Also included were an instrument panel from the Pontiac Grand Prix featuring a Rally Gauge Cluster with full Fuel, Oil, Water and Volts instrumentation ( tachometer or fuel economy gauge optional-on cars so equipped, the clock was moved to a space on the lower instrument panel under the radio ), three-spoke padded steering wheel with brushed-stainless spokes, and Genuine Crossfire African Mahogany trim on the dash facing, radio and clock surrounds, as well as the center console between the front seats.

The whole instrument is enclosed within three stone and concrete chambers with swell shutters facing upwards, except the Tuba box which speaks down into the transept.

Two musicians position themselves facing each other, holding the instrument between them, and use their fingers, drum sticks, or the palms of their hands to strike the skins, producing quite rapid melodies.

There are several factors involved in producing different pitches on a brass instrument: One is alteration of the player's lip tension ( or " embouchure "), and another is air flow.

Unlike woodwind instruments with reeds, a flute is an aerophone or reedless wind instrument that produces its sound from the flow of air across an opening.

The presence of the measuring instrument inevitably acts to divert flow and create turbulence, so its shape is critical to accuracy and the calibration curves are often non-linear.

Depressing a key on the keyboard causes the instrument to produce sounds, either by mechanically striking a string or tine ( piano, electric piano, clavichord ); plucking a string ( harpsichord ); causing air to flow through a pipe ( organ ); or strike a bell ( carillon ).

A pitot () tube is a pressure measurement instrument used to measure fluid flow velocity.

The field of the instrument is energized by the circuit current flow.

For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used.

An instrument is a device that measures and / or regulates physical quantity / process variables such as flow, temperature, level, or pressure.

Players of wind instruments generally create vibrato by modulating their air flow into the instrument.

The sizes of the macromolecules are measured as they elute into the flow cell of the DLS instrument from the size exclusion column set.

For an instrument whose payment stream is described by f ( t ), the value V ( t ) satisfies the inhomogeneous first-order ODE (" inhomogeneous " is because one has f rather than 0, and " first-order " is because one has first derivatives but no higher derivatives ) – this encodes the fact that when any cash flow occurs, the value of the instrument changes by the value of the cash flow ( if you receive a $ 10 coupon, the remaining value decreases by exactly $ 10 ).

In its simplest electronic form, the instrument consists of an air bottle connected to the external atmosphere through a sensitive air flow meter.

A Pitot tube is a pressure measuring instrument used to measure fluid flow velocity by determining the stagnation pressure.

More holes allow the instrument to measure the direction of the flow velocity in addition to its magnitude ( after appropriate calibration ).

Debt factoring is also used as a financial instrument to provide better cash flow control especially if a company currently has a lot of accounts receivables with different credit terms to manage.

* Pitot tube, a pressure measurement instrument used to measure fluid flow velocity

A flow cytometer is an instrument that can examine the expression of molecules on individual cells in fluids.

Soon after, flow cytometry instruments were developed, including the Cytofluorograph ( 1971 ) from Bio / Physics Systems Inc. ( later: Ortho Diagnostics ), the PAS 8000 ( 1973 ) from Partec, the first FACS instrument from Becton Dickinson ( 1974 ), the ICP 22 ( 1975 ) from Partec / Phywe and the Epics from Coulter ( 1977 / 78 ).

Interaction between the air reed and the air column in the body of the instrument produces oscillation in the flow of air at the windway.

One common laboratory instrument is the reaction calorimeter, where the heat flow into or from the reaction vessel is monitored.

It is a highly sensitive instrument designed to acquire and record data of low-level aerodynamic acceleration along the orbiter's principal axes in the free-molecular flow regime at orbital altitudes and in the transition regime during re-entry.

An aerovane combines a propeller and a tail on the same axis to obtain accurate and precise wind speed and direction measurements from the same instrument.

* Wind profiler, an instrument to measure wind speed and direction at various elevations above the ground

This instrument provided crucial data indicating that the distribution of GRBs is isotropic — not biased towards any particular direction in space, such as toward the galactic plane or the galactic center.

For many purposes and physical circumstances, the error in direction that results from ignoring the distinction is tolerable ; in others a mental or instrument compensation, based on assumed knowledge of the applicable declination, can solve all the problems.

This instrument possessed many advantages ; it was more exact, took a correct measurement in every direction, was contained in a small compass, and could be used on either the model or the marble.

A magnetometer is a measuring instrument used to measure the strength or direction of magnetic fields.

An automatic direction finder ( ADF ) is a marine or aircraft radio-navigation instrument that automatically and continuously displays the relative bearing from the ship or aircraft to a suitable radio station.

The term variometer also refers to a type of variable transformer or an instrument for measuring the magnitude and direction of a Magnetic field.

While not sensitive enough to detect distant earthquakes, this instrument could indicate the direction of the pressure waves and thus help find the epicenter of a local earthquake – such instruments were useful in the analysis of the 1906 San Francisco earthquake.

Along Tower Beach are two tall concrete range / direction instrument towers that are relics from World War II.

While the compass is the primary instrument used to determine one's heading, pilots will usually refer instead to the direction indicator ( DI ), a gyroscopically driven device which is much more stable than a compass.

* arco: the bow used for playing some string instrument ; i. e., played with the bow, as opposed to pizzicato ( plucked ), in music for bowed instruments ; normally used to cancel a pizzicato direction

A weather vane ( or weathercock ) is an instrument for showing the direction of the wind

The instrument serves the user to determine the correct ' qibla ' - the direction to which Muslims turn in prayer to face the Ka ' ba in Mecca.

A compass is a navigational instrument that indicates the direction to the magnetic poles.

* Magnetometer, an instrument for measuring magnetic field strength and direction

In this kind of instrument, there are two yaw direction tubes which are chamfered and silver soldered symmetrically on the two sides of a pitot tube.

In particular, a light pulse enters the instrument through a narrow slit along one direction.

The direction and further follow-up by the Supreme Court has been a major instrument in universalising the scheme.

They are usually identified as major airway intersections where aircraft, operating under instrument flight rules, often change direction of flight while en route.

* Compass: Navigational instrument showing the direction of the vessel in relation to the Earth's geographical poles or magnetic poles.

Rotation about the vertical axis varies the azimuth ( compass bearing ) of the pointing direction of the instrument.
