At the instant of any observation of an object, the apparent position of the object is displaced from its true position by an amount which depends solely upon the transverse component of the velocity of the observer, with respect to the vector of the incoming beam of light ( i. e., the line actually taken by the light on its path to the observer ).

The ecliptic is actually the apparent path of the Sun throughout the course of a year.

In addition to issues of reliability, the dynamic nature and the diversity of the Internet and its components provide no guarantee that any particular path is actually capable of, or suitable for, performing the data transmission requested, even if the path is available and reliable.

* C ++ by default follows each inheritance path separately, so a object would actually contain two separate objects, and uses of's members have to be properly qualified.

All these motions are actually " orbits " in a technical sense — they are describing a portion of an elliptical path around the center of gravity — but the orbits are interrupted by striking the Earth.

But when you actually begin to tread on the path, you realize that you have to clear out the jungle and all the trees, underbrush, and obstacles growing in front of you.

By taking the derivative of the optical path length, the stationary point is found giving the path taken by the light ( though it should be noted that the result does not show light taking the least time path, but rather one that is stationary with respect to small variations as there are cases where light actually takes the greatest time path, as in a spherical mirror ).

However, the northwest-to-southeast path the road actually takes, serves in two capacities: as an east – west interstate highway north of Interstate 90 in New England, and as a substantial part of the main connection between the major cities of Montreal and Boston.

At Lewes, we actually walked along the same path that Simon de Montfort and his men would have followed.

Because the river runs at a southeast angle, the roads of Wisner run a similar path, and very few roads in Wisner actually run truly north, south, east or west, but at a severely altered angle.

Hamilton's principle states that the physical path q ( t )— the one actually taken by the system — is a path for which infinitesimal variations in that path cause no change in I, at least up to first order.

The brown residue deposited on swabs during cleaning of a tape machine's tape path is actually particles of magnetic coating shed from tapes.

However, studies done at the University of Kentucky suggest traps attract more beetles than they actually trap, thus causing more damage along the flight path of the beetles and in the vicinity of the trap than may have occurred if the trap were not present.

While creating this new path, the algorithm decides how many new ' nodes ' to add and whether or not these new nodes will actually create a new path.

Eventually, reusable stages will take over, but I actually think that we can make it all the way to orbit on our current budget by following this path.

While parenting is sometimes held as the necessary path of adulthood, studies are actually mixed as to whether parents are more likely to report being happier than non-parents.

It turns out that the anthropologist's civilization is actually heading down the same path.

The entire system is in motion, so the spacecraft will not actually hit the Moon, but will travel in a winding path, off into space.

As he reflects on Moira's words, Xavier gives Cyclops his blessing to lead the X-Men and leaves to find his own path.

One manifestation of this view is found in the cognitive science of mathematics, where it is proposed that mathematics itself, the most widely accepted means of abstraction in the human community, is largely metaphorically constructed, and thereby reflects a cognitive bias unique to humans that uses embodied prototypical processes ( e. g. counting, moving along a path ) that are understood by all human beings through their experiences.

Low winter sun ( see Sun path ) reflects off the snow and increases solar gain through equator-facing glass by one-to-two thirds which brightly lights the ceiling of these rooms.

It has been theorized that the placement of the sixty sexagenary terms on the points of the Liubo divination diagram indicate the possible positions for placing pieces when playing Liubo, and that the sequence of the terms across the divination diagram reflects the path to be followed around the board when playing the game ( starting at the north-east corner and ending at the north side of the central square ).

One of the interesting aspects of some Schiefspieglers is that one of the mirrors can be involved in the light path twice — each light path reflects along a different meridional path.

This story reflects Jamī's idea of the Sufi-king as the ideal medieval Islamic ruler to repent and embark upon the Sufi path to realize his rank as God's ' true ' vicegerent and become closer to God.

This choice reflects Debré's fear that what remained of the French colonial empires would follow the path trodden by Algeria – that of independence, towards which he was not sympathetic.

Whether this represents a denial or a transcendence of the racialized consciousness that his peers ' writing so often reflects, Alexis's quirky fiction seems destined to follow its own singular path through the contemporary literary landscape.

Working in the field of feminist literary theory and criticism, which was just emerging as a serious scholarly pursuit in universities in the 1970s, Showalter's writing reflects a conscious effort to convey the importance of mapping her discipline ’ s past in order to both ground it in substantive theory, and amass a knowledge base that will be able to inform a path for future feminist academic pursuit.

The novel closes with a poetic epilogue that reflects Prus ' own path through life.

" In celebrating WED in Brazil in 2012, we are returning to the roots of contemporary sustainable development in order to forge a new path that reflects the realities but also the opportunities of a new century ," said Achim Steiner, UN Under-Secretary General and UNEP Executive Director.

The forward linguistic path also reflects cultural and historical transactions ; often the name of an animal comes from Germanic while the name of its cooked meat comes from Romance.

Networking advances IEEE 802. 1aq ( SPB ) include the use of the link-state routing protocol IS-IS to allow larger networks with shortest path routes between devices.

Oskar Sandberg's research ( during the development of version 0. 7 ) shows that this " path folding " is critical, and that a very simple routing algorithm will suffice provided there is path folding.

Routers in the transmission path simply forward packets to the next known local gateway matching the routing prefix for the destination address.

Since routing is dynamic for every packet and the network maintains no state of the path of prior packets, it is possible that some packets are routed on a longer path to their destination, resulting in improper sequencing at the receiver.

The works of the Brightfields had a similar two-dimensional form but used a variety of graphics-oriented " path obscuring " techniques – although the routing was comparable to or simpler than Koziakin's mazes, the Brightfield's mazes did not allow the various pathway options to be discerned so easily by the roving eye as it glanced about.

Multiprotocol Label Switching ( MPLS ) is a mechanism in high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table.

Meanwhile, in an IP network with MPLS Traffic Engineering CSPF routing, constraints such as the RSVP bandwidth of the traversed links can also be considered, such that the shortest path with available bandwidth will be chosen.

For end-users the use of MPLS is not visible directly, but can be assumed when doing a traceroute: only nodes that do full ip routing are shown as hops in the path, thus not the MPLS nodes used in between, therefore when you see that a packet hops between two very distant nodes and hardly any other ' hop ' is seen in that providers network ( or AS ) it is very likely that that network uses MPLS.

Most routing algorithms use only one network path at a time, but multipath routing techniques enable the use of multiple alternative paths.

In path vector routing we assume there is one node ( there can be many ) in each autonomous system which acts on behalf of the entire autonomous system.

Path vector routing is discussed in RFC 1322 ; the path vector routing algorithm is somewhat similar to the distance vector algorithm in the sense that each border router advertises the destinations it can reach to its neighboring router.

A route is defined as a pairing between a destination and the attributes of the path to that destination, thus the name, path vector routing, where the routers receive a vector that contains paths to a set of destinations.

The path, expressed in terms of the domains ( or confederations ) traversed so far, is carried in a special path attribute that records the sequence of routing domains through which the reachability information has passed.

In the case of computer networking, the metric is computed by a routing algorithm, and can cover such information as bandwidth, network delay, hop count, path cost, load, MTU, reliability, and communication cost ( see e. g. this survey for a list of proposed routing metrics ).

In some networks, routing is complicated by the fact that no single entity is responsible for selecting paths: instead, multiple entities are involved in selecting paths or even parts of a single path.

In choosing the single router-level path, it is common practice for each ISP to employ hot-potato routing: sending traffic along the path that minimizes the distance through the ISP's own network — even if that path lengthens the total distance to the destination.
