* The prediction of the molecular structure of molecules by the use of the simulation of forces, or more accurate quantum chemical methods, to find stationary points on the energy surface as the position of the nuclei is varied.

This process of determining stationary points is called geometry optimization.

More importantly, it allows for the characterization of stationary points.

Germany's Puma and Sweden's CV90 can fire air burst munitions that contain hundreds of tungsten rods that are effective against vehicles, helicopters, and stationary strong points.

* Mathematical optimization, the theory and computation of extrema or stationary points of functions

A sinusoidal standing wave includes stationary points of no motion, called nodes, and the wavelength is twice the distance between nodes.

Once the axis points toward the celestial pole, it will appear to be stationary and won't experience any more frictional forces.

At wavelengths of 30 meters to 3 meters ( 10 MHz-100 MHz ), they are generally either directional antenna arrays similar to " TV antennas " or large stationary reflectors with moveable focal points.

If f is a differentiable function on R ( or an open interval ) and x is a local maximum or a local minimum of f, then the derivative of f at x is zero ; points where are called critical points or stationary points ( and the value of f at x is called a critical value ).

All motion is from east to west, except for the two stationary points.

If is a maximum of for the original constrained problem, then there exists such that is a stationary point for the Lagrange function ( stationary points are those points where the partial derivatives of are zero, i. e. ).

However, not all stationary points yield a solution of the original problem.

Once we have located the stationary points, we need to do further tests to see if we have found a minimum, a maximum or just a stationary

For a single constraint, we use the statement above to say that at stationary points the direction that changes f is in the same direction

constraint, we end up with 2 simultaneous equations that when solved, identify all constrained stationary points:

( using this new terminology ) that at the stationary points, the direction that changes f is in the “ violation space ” created by the

constraint, we end up with simultaneous equations that when solved, identify all constrained stationary points:

The method is complete now ( from the standpoint of solving the problem of finding stationary points ) but as mathematicians delight in

Analysis of observations including both stationary and mobile ( surface and aerial ) in-situ and remote sensing ( passive and active ) instruments generates new ideas and refines existing notions.

A compass is a navigational instrument that measures directions in a frame of reference that is stationary relative to the surface of the earth.

But with respect to the Earth's surface, the compass will appear to be stationary and pointing along the Earth's surface toward the true North Pole.

In this they move across the water surface holding and moving their feet on the water's surface while holding steady above the water, and remaining stationary by hovering with rapid fluttering or by using the wind to anchor themselves in place.

* Frictional brakes are most common and can be divided broadly into " shoe " or " pad " brakes, using an explicit wear surface, and hydrodynamic brakes, such as parachutes, which use friction in a working fluid and do not explicitly wear. Typically the term " friction brake " is used to mean pad / shoe brakes and excludes hydrodynamic brakes, even though hydrodynamic brakes use friction. Friction ( pad / shoe ) brakes are often rotating devices with a stationary pad and a rotating wear surface.

A guide to the symbols for weather fronts that may be found on a weather map: 1. cold front 2. warm front 3. stationary front 4. occluded front 5. surface trough 6. squall line 7. dry line 8. tropical wave

A geostationary satellite therefore ideally remains stationary relative to the Earth's surface, staying over a single point on the equator.

Since the Earth is in motion, two main possibilities were considered: ( 1 ) The aether is stationary and only partially dragged by Earth ( proposed by Augustin-Jean Fresnel in 1818 ), or ( 2 ) the aether is completely dragged by Earth and thus shares its motion at Earth's surface ( proposed by George Gabriel Stokes in 1844 ).

One requirement for SEC is that the analyte does not interact with the surface of the stationary phases.

An underpacked column can reduce the relative surface area of the stationary phase accessible to smaller species, resulting in those species spending less time trapped in pores.

Any object that is stationary with respect to the surface of the Earth is actually following a circular trajectory, circumnavigating the Earth's axis.

Translating this analogy into space, then, a " stationary " observer sees a planet moving left at speed U and a spaceship moving right at speed v. If the spaceship has the proper trajectory, it will pass close to the planet, moving at speed U + v relative to the planet's surface because the planet is moving in the opposite direction at speed U. When the spaceship leaves orbit, it is still moving at U + v relative to the planet's surface but in the opposite direction ( to the left ).

Also known as normal-phase HPLC ( NP-HPLC ), or adsorption chromatography, this method separates analytes based on their affinity for a polar stationary surface such as silica, hence it is based on analyte ability to engage in polar interactions ( such as hydrogen-bonding or dipole-dipole type of interactions ) with the sorbent surface.

Very polar solvents such as traces of water in the mobile phase tend to adsorb to the solid surface of the stationary phase forming a stationary bound ( water ) layer which is considered to play an active role in retention.

The binding of the analyte to the stationary phase is proportional to the contact surface area around the non-polar segment of the analyte molecule upon association with the ligand on the stationary phase.

A local ( energy ) minimum is a stationary point where all such displacements lead to an increase in energy.

The experimental apparatus consisted of a torsion balance with a pair of 2-inch 1. 61-pound lead spheres suspended from the arm of a torsion balance and two much larger stationary lead balls ( 350 pounds ), and Cavendish intended to measure the force of gravitational attraction between the two.

Whilst lead – acid batteries can be charged by simply connecting a dynamo to them, with a simple electromagnetic cut-out system for when the dynamo is stationary or an over-current occurs, the Ni – Cd battery under a similar charging scheme would exhibit thermal runaway, where the charging current would continue to rise until the over-current cut-out operated or the battery destroyed itself.

Other mutations on rhodopsin lead to X-linked congenital stationary night blindness, mainly due to constitutive activation, when the mutations occur around the chromophore binding pocket of rhodopsin.

With a reference frame of a stationary shock, the following flow is subsonic, so that an acoustic reaction zone follows immediately behind the lead front, the Chapman-Jouguet condition.

In stationary steam engines, traction engines and marine engine practice, the shortcomings of valves and valve gears were among the factors that lead to compound expansion.

A poorly implemented motion compensation algorithm would interfere with natural motion and could lead to visual artifacts which manifest as " jumping " parts in what should be a stationary or a smoothly moving image.

On 19 September, with Karluk ice-bound and largely stationary, Stefansson announced that in view of the shortage of fresh meat and the likelihood of a long sojourn in the ice, he would lead a small hunting party that would search for caribou and other game in the area of the Colville River.

* Jun-tsuki punch with the lead arm when stationary or moving back / away

Proponents of free energy devices have advanced the theory that the lead plating interrupts the magnetic attraction between the rim magnets and the stationary magnet in sequence, thus permitting the wheel to continue turning and bring the next rim magnet into position.

However, the presence of lead dampens magnetic fields equally in any directions ( as a magnet's field lines must stay continuous from pole to pole ), and the symmetry of closed forces in the system means that no interaction between rim magnets and the stationary magnets could generate the net increase in energy necessary to keep the wheel rotating.

He took the lead after the first round of pit stops, but on that first stop under yellow he bumped a stationary tyre in the pit stall ahead of him.
