The usual definition of numerical stability uses a more general concept, called mixed stability, which combines the forward error and the backward error. An algorithm is stable in this sense if it solves a nearby problem approximately, i.e., if Δx is small and f(x + Δx) − y* is small. Hence, a backward stable algorithm is always stable. An algorithm is forward stable if its forward error divided by the condition number of the problem is small. This means that an algorithm is forward stable if has a ...

(It seems that here the author assumes that the transfer function of the system is rational. Can someone confirm if this is true also for nonrational transfer functions? References?) Stability (in control theory) often means that for any bounded input over any amount of time, the output will also be bounded. This is known as BIBO stability (see also Lyapunov stability). If a system is BIBO stable then the output cannot "blow up" if the input remains finite. Mathematically, this means that for a linear continuous-time system to ...

Only a narrow range of possible values for R1, R2, and L produce stable resonators in which periodic refocussing of the intracavity beam is produced. If the cavity is unstable, the beam size will grow without limit, eventually growing larger than the size of the cavity mirrors and being lost. By using methods such as ray transfer matrix analysis, it is possible to calculate a stability criterion: . Values which satisfy the inequality correspond to stable resonators. The stability can be shown graphically by defining a stability parameter, ...

Yucca Mountain - Geology. Yucca Mountain is located within Nye County in south central Nevada. The formation that makes up Yucca Mountain was created by several large eruptions from a caldera volcano and is composed of alternating layers of welded-tuff, non-welded tuff, and semi-welded tuff. Tuff has special physical, chemical and thermal characteristics that some experts believe make it a suitable material to entomb radioactive waste for the hundreds of thousands of years required for the was ...

Stability (in control theory) often means that for any bounded input over any amount of time, the output will also be bounded. This is known as BIBO stability (see also Lyapunov stability). If a system is BIBO stable then the output cannot "blow up" if the input remains finite. Mathematically, this means that for a linear continuous-time system to be stable all of the poles of its transfer function must lie in the closed left half of the complex plane if the Laplace transform is used (i.e. its rea ...

Fixed wing aircraft are designed to be inherently stable. If a gust of wind or a nudge to one of the controls causes a fixed wing aircraft to pitch, roll, or yaw, the aerodynamic design of the aircraft will tend to correct the motion, and the aircraft will return to its original attitude. A small, fixed wing aircraft can be stable enough that a pilot can let go of the controls while looking at a map or dealing with a radio, and ...

From the region of convergence of the Z-transform, the stability of an IIR filter can be evaluated. If all poles are within the unit circle (i.e., | zp | < 1) then the filter is stable. By definition of the region of convergence, then if the system is stable then will hold true. Otherwise, if the system is unstable then the sum will be . IIR filters are sometimes preferred over FIR filters because an IIR filter can achieve a much sharper transitio ...

The concept of stability, useful in the analysis of many kinds of equilibrium can also be applied to Nash equilibria. A Nash equilibrium for a mixed strategy game is stable if a small change (specifically a infinitesimal change) in probabilities for one player leads to a situation where two conditions hold: the player who did not change has no better strategy in the new circumstance the player who did change is now ...

The first three Lagrangian points are technically stable only in the plane perpendicular to the line between the two bodies. This can be seen most easily by considering the L1 point. A test mass displaced perpendicularly from the central line would feel a force pulling it back towards the equilibrium point. This is because the lateral components of the two masses' gravity would add to produce this force, whereas the components along the axis between them would balance out. However, if an object located at the L1 point d ...

Despite the popularity of video games, work in this area is very volatile. Scores of game development studios crop up, work on one game, and then quickly go under. This may be one reason why game developers tend to congregate in one geographic area—once their current studio goes under, they flock to an adjacent one or start another from the ground up. In an industry where only the top 5% of products make a profit, it's easy to understand this fluctuation. Numerous games go into development and are either canceled or completed, but n ...

The vertical stabilizer or fin of an aircraft is found on its tail, generally pointing straight upward. It is also known as the vertical tail, and is part of an aircraft's empennage. The trailing end of the stabilizer is typically movable, and called the rudder; this allows the aircraft to yaw. Often navigational radios have their antennas placed on or in the vertical tail. In some aircraft, the vertical stabilizer houses the engine; the Lockheed L-1011, McDonnell Douglas DC-10, McDonnell Douglas MD-11, Boeing 727, Tupolev Tu-1 ...
