DCT (videocassette Format)
DCT is a digital recording component video videocassette format developed and introduced by Ampex in 1992. It was based on the D1 format, and unlike the uncompressed recording scheme of D1, it was the first digital videotape format to use data compression. Like D1 (and D2), it uses a similar cassette loaded with 3/4" (19mm) width tape. One of the models of VCR released for the format was the Ampex DCT-1700D. Overview The type of data compression used by the format, discrete cosine transform (DCT), shares the same acronym as the format, but the meaning is different for the latter (the format's acronym meaning Data Component Technology).Mika Iisakkila, ''Video recording formats'' DST (Data Storage Technology), a data-only version of DCT, was also developed by Ampex at the same time for the backup and archiving of data from servers and other enterprise-oriented IT systems. However, it was used by television networks such as Fox and The Discovery Channel in the late 1990s to e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discovery Channel Telescope
The Lowell Discovery Telescope (LDT), formerly the Discovery Channel Telescope (DCT), is a aperture telescope owned and operated by Lowell Observatory. The LDT was built at a dark sky site in the Coconino National Forest near Happy Jack, Arizona. Happy Jack is located at an elevation of and is approximately south-south-east of Flagstaff. The project was initially a partnership between Discovery Communications and Lowell Observatory. The research partnerships have been extended to include Boston University, The University of Maryland, The University of Toledo, Northern Arizona University, and Yale University. The telescope cost $53 million. It significantly augments Lowell Observatory's observational capability and enables pioneering studies in a number of important research areas. With its 4-meter class primary mirror, the Lowell Discovery Telescope is the fifth largest telescope in the continental United States (). Final construction of the telescope was completed by ...

Dual-clutch Transmission
A dual-clutch transmission (DCT) (sometimes referred to as a twin-clutch transmission) is a type of multi-speed motor vehicle, vehicle Transmission (mechanics), transmission system, that uses two separate clutches for odd and even gear train, gear sets. The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit. In car and truck applications, the DCT functions as an automatic transmission, requiring no driver input to change gears. The first DCT to reach production was the ''Easidrive'' automatic transmission introduced on the Hillman_Minx#Audax_design_Hillman_Minx_(Series_I_to_Series_VI,_1956–1967), 1961 Hillman Minx mid-size car. This was followed by various eastern European tractors through the 1970s (using manual operation via a single clutch pedal), then the Porsche 962, Porsche 962 C racing car in 1985. The first DCT of the modern era was used in the 2003 Volkswagen Golf Mk4#R32 ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Coombs Test
The direct and indirect Coombs tests, also known as antiglobulin test (AGT), are blood tests used in immunohematology. The direct Coombs test detects antibodies that are stuck to the surface of the red blood cells. Since these antibodies sometimes destroy red blood cells they can cause anemia; this test can help clarify the condition. The indirect Coombs test detects antibodies that are floating freely in the blood. These antibodies could act against certain red blood cells; the test can be carried out to diagnose reactions to a blood transfusion. The direct Coombs test is used to test for autoimmune hemolytic anemia, a condition where the immune system breaks down red blood cells, leading to anemia. The direct Coombs test is used to detect antibodies or complement proteins attached to the surface of red blood cells. To perform the test, a blood sample is taken and the red blood cells are washed (removing the patient's plasma and unbound antibodies from the red blood cells) and t ...

Distal Convoluted Tubule
The distal convoluted tubule (DCT) is a portion of kidney nephron between the loop of Henle and the collecting tubule. Physiology It is partly responsible for the regulation of potassium, sodium, calcium, and pH. On its apical surface (lumen side), cells of the DCT have a thiazide-sensitive Na-Cl cotransporter and are permeable to Ca, via the TRPV5 channel. On the basolateral surface (peritubular capillary side) there is an ATP-dependent Na/K antiporter pump, a secondary active Na/Ca transporter, and an ATP dependent Ca transporter. The basolateral ATP dependent Na/K pump produces the gradient for Na to be absorbed from the apical surface via the Na/Cl symporter, and for Ca to be reclaimed into the blood by the Na/Ca basolateral antiporter. * It regulates pH by absorbing bicarbonate and secreting protons (H+) into the filtrate, or by absorbing protons and secreting bicarbonate into the filtrate. * Sodium and potassium levels are controlled by secreting K+ and absorbing ...

Discrete Cosine Transform
A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequency, frequencies. The DCT, first proposed by Nasir Ahmed (engineer), Nasir Ahmed in 1972, is a widely used transformation technique in signal processing and data compression. It is used in most digital media, including digital images (such as JPEG and HEIF), digital video (such as MPEG and ), digital audio (such as Dolby Digital, MP3 and Advanced Audio Coding, AAC), digital television (such as SDTV, HDTV and Video on demand, VOD), digital radio (such as AAC+ and DAB+), and speech coding (such as AAC-LD, Siren (codec), Siren and Opus (audio format), Opus). DCTs are also important to numerous other applications in science and engineering, such as digital signal processing, telecommunication devices, reducing network bandwidth usage, and spectral methods for the numerical solution of partial differential equations. A DCT is a List of Fourier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominated Convergence Theorem
In measure theory, Lebesgue's dominated convergence theorem gives a mild sufficient condition under which limits and integrals of a sequence of functions can be interchanged. More technically it says that if a sequence of functions is bounded in absolute value by an integrable function and is almost everywhere pointwise convergent to a function then the sequence converges in L_1 to its pointwise limit, and in particular the integral of the limit is the limit of the integrals. Its power and utility are two of the primary theoretical advantages of Lebesgue integration over Riemann integration. In addition to its frequent appearance in mathematical analysis and partial differential equations, it is widely used in probability theory, since it gives a sufficient condition for the convergence of expected values of random variables. Statement Lebesgue's dominated convergence theorem. Let (f_n) be a sequence of complex-valued measurable functions on a measure space . Suppose that t ...

Director Control Tower
This article explains terms used for the British Armed Forces' ordnance (weapons) and ammunition. The terms may have different meanings depending on their usage in another country's military. BD Between decks: applies to a naval gun mounting in which part of the rotating mass is below the deck, and part of it is above the deck. This allows for a lower profile for a turret, meaning that the turrets need not be superfiring (i.e. they can be mounted on the same deck and not obstruct each other at high angles of elevation). BL The term BL, in its general sense, stood for breech loading, and contrasted with muzzle loading. The shell was loaded via the breech (i.e. the gunner's end of the barrel, which opened) followed by the propellant charge, and the breech mechanism was closed to seal the chamber. Breech loading, in its formal British ordnance sense, served to identify the gun as the type of rifled breechloading gun for which the powder charge was loaded in a silk or cloth bag an ...

Discourse-completion Task
A Discourse-Completion Task (DCT) is a tool used in linguistics and pragmatics to elicit particular speech acts. A DCT consists of a one-sided role play containing a situational prompt which a participant will read to elicit the responses of another participant. Background The instrument was originally developed by Shoshana Blum-Kulka for studying speech act realization comparatively between native and non-native Hebrew speakers, based on the work of E. Levenston.Blum-Kulka, S., House, J., & G. Kasper. (1989). Investigating cross-cultural pragmatics: An introductory overview. In Blum-Kulka, S., House, J., & G. Kasper (Eds.), Cross-cultural pragmatics: Requests and apologies (pp. 1-34). Norwood, NJ: Ablex, p. 13-14 DCTs are used in pragmatics research to study speech acts and find the medium between naturally occurring speech and scripted speech acts. In comparing role-plays to DCTs, role-plays are considered to elicit data more similar to naturally occurring speech acts, yet are c ...
