Interference (communication)
In telecommunications, an interference is that which modifies a signal in a disruptive manner, as it travels along a communication channel between its source and receiver. The term is often used to refer to the addition of unwanted signals to a useful signal. Common examples include: * Electromagnetic interference (EMI) * Co-channel interference (CCI), also known as crosstalk * Adjacent-channel interference (ACI) * Intersymbol interference (ISI) * Inter-carrier interference (ICI), caused by doppler shift in OFDM modulation (multitone modulation). * Common-mode interference (CMI) * Conducted interference Noise is a form of interference but not all interference is noise. Radio resource management aims at reducing and controlling the co-channel and adjacent-channel interference. Interference alignment A solution to interference problems in wireless communication networks is interference alignment, which was crystallized by Syed Ali Jafar at the University of California, ...

Viral Interference
Viral interference, also known as superinfection resistance, is the inhibition of viral reproduction caused by previous exposure of cells to another virus. The exact mechanism for viral interference is unknown. Factors that have been implicated are the generation of interferons by infected cells, and the occupation or down-modulation of cellular receptors. __TOC__ Overview Viral interference is considered the most common outcome of coinfection, or the simultaneous infection of a host by two or more distinct viruses. The primary form of viral interference is known as superinfection exclusion, in which the initial infection stimulates a resistance to subsequent infection by related viruses. Interference can occur as well in the form of superinfection suppression, in which persistently infected cells hold off infection by unrelated viruses. Viral interference has also been observed to occur in the use of vaccines containing live-attenuated viruses, in both directions — in so ...

Interfering Thread Nut
An interfering thread nut is a type of locknut A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut,. stiff nut or elastic stop nut, is a nut that resists loosening under vibrations and torque. Prevailing torque nuts have some portion of the nut that de ... that has an undersized root diameter. This creates an interference between the nut and the fastener, plastically deforming the threads on the fastener. Due to this deformation they are usually only used on permanent or semi-permanent installations.. A variation of this nut is the tapered thread nut. It utilizes a tapered thread to achieve the interference. The nut goes on easily, because the thread diameter starts at a standard size; as the nut is further threaded on it begins to lock, much like a distorted thread locknut.

Interference Proceeding
An interference proceeding, also known as a priority contest, is an inter partes proceeding to determine the priority issues of multiple patent applications. It is a proceeding unique to the patent law of the United States. Unlike in most other countries, which have long had a first-to-file system, until the enactment of the Leahy-Smith America Invents Act (AIA) in 2011, the United States operated under a first-to-invent. The interference proceeding determines which of several patent applications had been made by the first inventor. The AIA switched the US to a first-to-file regime effective March 16, 2013, and interferences apply only to patent applications with an effective filing date prior to that change. Definition An interference proceeding is an administrative proceeding conducted by a panel of administrative patent judges ( administrative law judges sitting on the Board of Patent Appeals and Interferences) of the United States Patent and Trademark Office (USPTO) to d ...

Interference (chess)
In the game of chess, interference occurs when the line between an attacked piece and its defender is interrupted by sacrificially interposing a piece. It is a chess tactic which seldom arises, and is therefore often overlooked. Opportunities for interference are rare because the defended object must be more valuable than the sacrificed piece, and the interposition must itself present a threat. Huczek defines interference as a tactic involving blocking moves that obstruct lines of attack. This definition may be expanded by including blocking moves that disrupt lines of defense. Examples In diagram A, White to play will apparently be obliged to retreat the knight from f5, because the squares to which it could advance are all guarded. The interference move 1.Nd6+, however, interrupts the black rook's defense of the black queen. If Black plays either 1...cxd6 or 1...Bxd6, White will capture Black's queen. Therefore, Black has no better play than 1...Rxd6 2.exd6 Qxe2 3.Rxe2 Bxd6, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interference (ice Hockey)
A penalty in ice hockey is a punishment for an infringement of the rules. Most penalties are enforced by sending the offending player to a penalty box for a set number of minutes. During the penalty the player may not participate in play. Penalties are called and enforced by the referee, or in some cases, the linesman. The offending team may not replace the player on the ice (although there are some exceptions, such as fighting), leaving them short-handed as opposed to full strength. When the opposing team is said to be on a ''power play'', they will have one more player on the ice than the short-handed team. The short-handed team is said to be "on the penalty kill" until the penalty expires and the penalized player returns to play. While standards vary somewhat between leagues, most leagues recognize several common varieties of penalties, as well as common infractions. The statistic used to track penalties is called "penalty minutes" and abbreviated to "PIM" (spoken as single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interference (baseball)
In baseball, interference occurs in situations in which a person illegally changes the course of play from what is expected. Interference might be committed by players on the offense, players not currently in the game, catchers, umpires, or spectators. Each type of interference is covered differently by the rules. Offensive interference The most common incidence of interference occurs when a member of the offensive team physically hinders the defensive team, decreasing its chances to make an out or increasing the chance that a baserunner will advance. Whenever this ''offensive interference'' occurs, the ball becomes dead. If the interference was committed by a batter or a baserunner, that player is called out and all other runners must return to the bases they occupied at the time of the interference. If interference is committed by a runner with the obvious intent of preventing a double play, the batter-runner will be called out in addition to the runner who committed the ...

Pass Interference
In American and Canadian gridiron football, pass interference (PI) is a foul that occurs when a player interferes with an eligible receiver's ability to make a fair attempt to catch a forward pass. Pass interference may include tripping, pushing, pulling, or cutting in front of the receiver, covering the receiver's face, or pulling on the receiver's hands or arms. It does not include catching or batting the ball before it reaches the receiver. Once the ball touches any defensive player or eligible offensive receiver, the above rules no longer apply and the defender may tackle the receiver or attempt to prevent them from gaining control of the ball. Once a forward pass is in the air it is a loose ball and thus any eligible receiver – all defensive players are eligible receivers – may try to catch it. When a defensive player catches a forward pass it is an interception and their team gains possession of the ball. Some actions that are defined as pass interference may be overlooke ...

Interference Theory
The interference theory is a theory regarding human memory. Interference occurs in learning. The notion is that memory encoded in long-term memory (LTM) are forgotten and cannot be retrieved into short-term memory (STM) because either memory could interfere with the other.Edwards, W. H. (2010). ''Motor Learning and Control: From Theory to Practice''. Belmont, CA: Cengage Learning. There is an immense number of encoded memories within the storage of LTM. The challenge for memory retrieval is recalling the specific memory and working in the temporary workspace provided in STM. Retaining information regarding the relevant time of encoding memories into LTM influences interference strength. There are two types of interference effects: proactive and retroactive interference. History John A. Bergström is credited with conducting the first study regarding interference in 1892. His experiment was similar to the Stroop task and required subjects to sort two decks of cards with words int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wave Interference
In physics, interference is a phenomenon in which two waves combine by adding their displacement together at every single point in space and time, to form a resultant wave of greater, lower, or the same amplitude. Constructive and destructive interference result from the interaction of waves that are correlated or coherent with each other, either because they come from the same source or because they have the same or nearly the same frequency. Interference effects can be observed with all types of waves, for example, light, radio, acoustic, surface water waves, gravity waves, or matter waves. Etymology The word ''interference'' is derived from the Latin words ''inter'' which means "between" and ''fere'' which means "hit or strike", and was coined by Thomas Young in 1801. Mechanisms The principle of superposition of waves states that when two or more propagating waves of the same type are incident on the same point, the resultant amplitude at that point is equal to th ...

Thin-film Interference
Thin-film interference is a natural phenomenon in which light waves reflected by the upper and lower boundaries of a thin film interfere with one another, either enhancing or reducing the reflected light. When the thickness of the film is an odd multiple of one quarter-wavelength of the light on it, the reflected waves from both surfaces interfere to cancel each other. Since the wave cannot be reflected, it is completely transmitted instead. When the thickness is a multiple of a half-wavelength of the light, the two reflected waves reinforce each other, increasing the reflection and reducing the transmission. Thus when white light, which consists of a range of wavelengths, is incident on the film, certain wavelengths (colors) are intensified while others are attenuated. Thin-film interference explains the multiple colors seen in light reflected from soap bubbles and oil films on water. It is also the mechanism behind the action of antireflection coatings used on glasses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
