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 ...

Interference (band)
Interference is an Irish band based around the late singer-songwriter Fergus O'Farrell. The band is featured in the Academy Award-winning movie ''Once''. Amidst the performances by the main characters, played by the Swell Season duo of Glen Hansard and Markéta Irglová, Interference have a cameo moment and play O'Farrell’s song "Gold". Interference have also had songs included in the soundtracks for Alan Gilsenan’s ''All Souls Day'' and Damien O’Donnell’s '' Inside I'm Dancing,'' both critically acclaimed films. A collaboration with Glen Hansard, the song ‘Don’t Go Down’ features in another John Carney film, ''Sing Street''. Interference have appeared three times on the Irish television show ''Other Voices''. One such appearance was a one-hour Interference special which led to the release of the live CD ''Interference Live in Dingle: Songs from Another Room''. In 2018, Trinity College Dublin’s Music Society awarded Interference an Honorary Patronage to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Interference'' was first published in October 2019 in the United States by Tor Books. The novel takes place on the planet Pax about 100 years after the events in ''Semiosis'' when a new expedition from Earth arrives. Plot summary About a hundred years after the events in ''Semiosis'', a new expedition to Pax from Earth is launched. Contact with the Pax colonists had been lost soon after they landed on the planet. On Pax the new arrivals find descendants of the original colonists living side-by-side in a glass city with alien arthropod-like Glassmakers, and Stevland, a sentient rainbow bamboo. Stevland oversees a fragile peace between the Pax humans and the Glassmakers. The Earthlings, as the new arrivals are called, interfere with this delicate balance, causing divisions in the colony and ...

Electromagnetic Interference
Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. The disturbance may degrade the performance of the circuit or even stop it from functioning. In the case of a data path, these effects can range from an increase in error rate to a total loss of the data. Both man-made and natural sources generate changing electrical currents and voltages that can cause EMI: ignition systems, cellular network of mobile phones, lightning, solar flares, and auroras (northern/southern lights). EMI frequently affects AM radios. It can also affect mobile phones, FM radios, and televisions, as well as observations for radio astronomy and atmospheric science. EMI can be used intentionally for radio jamming, as in electronic warfare. History Since the earliest days of rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interference (film)
''Interference'' is a 1928 American drama film directed by Lothar Mendes and starring Clive Brook, William Powell, Evelyn Brent, and Doris Kenyon, all making their sound film debuts. In England when a first husband turns out not to be dead, blackmail leads to murder. Production The film was originally produced as a silent which was directed by Lothar Mendes. However, after its completion, Paramount halted its release and decided to remake the film completely in sound. The sound version was directed by special effects technician-turned-director Roy J. Pomeroy, as the basis for Paramount Pictures' first feature-length all-talking motion picture. Since Pomeroy lacked experience as a director, he was assisted by William deMille during the filming. It was based on the 1927 West End play ''Interference'' by Roland Pertwee and Harold Dearden. It was shot on a budget of $250,000 A silent version was also released to cater for theaters that had not yet wired for sound. While the sound ...

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 ...

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, ...

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] |
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] |
