The component S1 of the system, situated between the aperture stop and the object O, projects an image of the diaphragm, termed by Abbe the entrance pupil ; the exit pupil is the image formed by the component S2, which is placed behind the aperture stop.

If the object point O is infinitely distant, u1 and u2 are to be replaced by h1 and h2, the perpendicular heights of incidence ; the sine condition then becomes sin u ' 1 / h1 = sin u ' 2 / h2.

We receive, therefore, in no single intercepting plane behind the system, as, for example, a focusing screen, an image of the object point ; on the other hand, in each of two planes lines O ' and O " are separately formed ( in neighboring planes ellipses are formed ), and in a plane between O ' and O " a circle of least confusion.

It is also the result of conical ( perspective ) projection of any of those geometric objects from a point O onto a plane P, provided that the plane Q that goes through O and is parallel to P does not cut the object.

: An object, O, changes with respect to property, P, if and only if O has P at one time, and at a later time, O does not have P.

A different ontology arises if we need to attend to the electrodynamics in the device: Here signals propagate at finite speed and an object ( like a resistor ) that was previously viewed as a single component with an I / O behavior may now have to be thought of as an extended medium through which an electromagnetic wave flows.

Oh Hell ( also known as Oh Pshaw, Up the River, Up and down the River, Bumble, Vanishing Whist, Diminishing Whist, Hell Yeah !, Peanuts, Stinky Fingers, Get Fred, Gary's Game, Diminishing Bridge, Shit On Your Neighbor, " Screw Your Neighbor ", O ' Shay, Juego de Daniel, Nah Pearse, Old Hell, German Bridge in Hong Kong, and many variations of " Oh Hell " with euphemisms and other swearwords ) is a trick-taking card game in which the object is to take exactly the number of tricks bid, unlike contract bridge and spades: taking more tricks than bid is a loss.

In many applications this linearity is an asset, because it enables simple, common I / O interfaces to be utilized to hold and pass on the state of an object.

An unidentified flying object, often abbreviated UFO or U. F. O., is an unusual apparent anomaly in the sky that is not readily identifiable to the observer as any known object, often associated with extraterrestrial life.

At the climax, O appears as a slave, nude but for an owl-like mask, before a large party of guests who treat her solely as an object.

Although this is in fact a shortening of the name Odile, it could also stand for " object " or " orifice ", an O being a symbolic representation of any " hole ".

Examples include " Hesperus is Phosphorus ", " Cicero is Tully ", " Water is H < sub > 2 </ sub > O " and other identity claims where two names refer to the same object.

Note that the zero morphism in item 3 can be identified as the identity element of the hom-set Hom ( A, B ), which is an abelian group by item 1 ; or as the unique morphism A → O → B, where O is a zero object, guaranteed to exist by item 2.

Rotation of a rigid object P about a fixed object about a fixed axis O.

If this article / noun pair is used as the object of a verb, it ( usually ) changes to the accusative case, which entails an article shift in German – Ich sehe den Wagen.

Furthermore, that maximum 5 % density change occurs at the stagnation point of an object immersed in the gas flow and the density changes around the rest of the object will be significantly lower.

These equations express mathematically that, in the case of an object that moves along a circular path with a changing speed, the acceleration of the body may be decomposed into a perpendicular component that changes the direction of motion ( the centripetal acceleration ), and a parallel, or tangential component, that changes the speed.

Loosely speaking, a derivative can be thought of as how much one quantity is changing in response to changes in some other quantity ; for example, the derivative of the position of a moving object with respect to time is the object's instantaneous velocity.

For electrical systems which use alternating current the electrodes are the connections from the circuitry to the object to be acted upon by the electric current but are not designated anode or cathode since the direction of flow of the electrons changes periodically, usually many times per second.

When an object changes, it always changes in some particular way.

Going back to the definition of " change ", an object changes with respect to a property if the object has that property at one time, and at a later time, the object does not have the property.

What changes is the fact that the object has a particular property.

When an object changes its color smoothly, the animation can be defined by keyframes — the first showing its original color, and the second showing its final color.

Typically, gravitational fields change only slightly over short distances, and the Earth ’ s field is nearly uniform at all locations on the Earth ’ s surface ; therefore, an object ’ s weight changes only slightly when it is moved from one location to another, and these small changes went unnoticed through much of history.

* In a plane mirror, a parallel beam of light changes its direction as a whole, while still remaining parallel ; the images formed by a plane mirror are virtual images, of the same size as the original object ( see mirror image ).

However, the court may object to the terms of proposed plea agreement ( even if already agreed between the defendant, victim and prosecutor ) and suggest changes ( not specific but rather general ).

However, changing the status of symbols between parameter and variable changes the function as a mathematical object.

For a relationist there can be no real difference between inertial motion, in which the object travels with constant velocity, and non-inertial motion, in which the velocity changes with time, since all spatial measurements are relative to other objects and their motions.

For each of the scene changes in this film, either Laurel or Hardy or both of them would seize a curtain or some other object at the edge of the frame and move it across the screen.

The technique works since the laser power ablates one side of the object, giving an impulse that changes the eccentricity of the object's orbit.

* State allows an object to alter its behavior when its internal state changes.

On the morning of November 17th, Cornwallis and 2,000 men had left Philadelphia with the object of capturing Fort Mercer at Red Bank, New Jersey.

But by comparison with the railroad, the motor car is a relatively new object of popular worship, so it is too much to hope that it may be brought within the bounds of civilized usage quickly and easily.

He had seen a dry, old, yellowing hand reach out, with that painful solicitude, to touch, to rearrange, to shift aimlessly, some object worth a pfennig.

One consequence is the occurrence of occasional conflicts because private owners of some inholdings object to public programs of use on neighboring National Forest or other Federal land, or because such ownerships are developed for uses that are not compatible with use for the public of neighboring National Forest land.

If a litigant chooses to enforce a Federal right in a State court, he cannot be heard to object if he is treated exactly as are plaintiffs who press like claims arising under State law with regard to the form in which the claim must be stated -- the particularity, for instance, with which a cause of action must be described.

more effective solutions include explanations, the example of another child, or conditioning by associating the feared object, place, or person with something pleasant.

Instead, he constantly became lost in parts and components of them, confused some of their details with those of neighboring objects, and so on, unless he allowed time to `` trace '' the object in question through minute movements of the head and hands and in this way to discover its contours.

As one would surmise, the procedure, however, could be repeated with the same object or with the same type of object often enough, so that the corresponding visual blots and the merest beginning of the tracing movement would provide clues as to the actual shape, which the patient then immediately could determine by a kind of inference.

The authors set about answering this fundamental question through a detailed investigation of the patient's ability, tactually, ( 1 ) to perceive figure and ( 2 ) to locate objects in space, with his eyes closed ( or turned away from the object concerned ).

The area may also be provided with additional data during the running of the object program by means of EDMOV or move macro-instructions.

By using instruments of gradually increasing size, the vagina is gently, and with minimum pain at each stage, taught to yield to an object of the appropriate shape.

Science is fully competent to deal with any element of experience which arises from an object in space and time.

The object of the game is to shoot and destroy asteroids and saucers while not colliding with either, or being hit by the saucers ' counter-fire.

These exceptions, introduced with a good object, had grown into a widespread evil by the 12th century, virtually creating an imperium in imperio, and depriving the bishop of all authority over the chief centres of influence in his diocese.

While a character with Pattern, Logrus or Conjuration can acquire virtually any object, players can choose to spend character points to obtain objects with particular virtues-unbreakability, or a mind of their own.

As with all radar measurements, these rely on measuring the time taken for photons to be reflected from an object.

A slab of rock with an iron staple in it to attach a chain to would serve the purpose, as would any dense object of appropriate weight ( e. g. an engine block ).

The justification for attributing life to objects was stated by David Hume in his Natural History of Religion ( Section III ): " There is a universal tendency among mankind to conceive all beings like themselves, and to transfer to every object those qualities with which they are familiarly acquainted, and of which they are intimately conscious.

The Aga Khan traveled in distant parts of the world to receive the homage of his followers, and with the object either of settling differences or of advancing their welfare by pecuniary help and personal advice and guidance.

As a youngster living in poverty, along with his childhood friends, Johnson was an object of ridicule from members of higher social circles ; as such, he was commonly referred to as " poor white trash " by the elite in Raleigh.
