25-letter words containing a, c, e, r, t, d
- point-and-grunt interface — point-and-drool interface
- polycystic ovary syndrome — a hormonal disorder in which the Graafian follicles in the ovary fail to develop completely so that they are unable to ovulate, remaining as multiple cysts that distend the ovary. The results can include reduced fertility, obesity, and hirsutism
- pressurized-water reactor — a nuclear reactor using water as coolant and moderator at a pressure that is too high to allow boiling to take place inside the reactor. The fuel is enriched uranium oxide cased in zirconium
- primary domain controller — (networking) (PDC) Each Windows NT domain has a Primary Domain Controller and zero or more Backup Domain Controllers. The PDC holds the SAM database and authenticates access requests from workstations and servers in the domain.
- programmed data processor — (computer) (PDP) Early (1960's?) Digital Equipment Corporation family of minicomputers. The best known ranges were the PDP-10 and PDP-11. PAL was the assembly language.
- property damage insurance — insurance against losses arising from damage to the property of others, as in a motor-vehicle accident.
- radio-controlled junction — A radio-controlled junction is a piece of equipment used to control underground pipelines which connect oil tanks.
- rate monotonic scheduling — (algorithm) A means of scheduling the time allocated to periodic hard-deadline real-time users of a resource. The users are assigned priorities such that a shorter fixed period between deadlines is associated with a higher priority. Rate monotonic scheduling provides a low-overhead, reasonably resource-efficient means of guaranteeing that all users will meet their deadlines provided that certain analytical equations are satisfied during the system design. It avoids the design complexity of time-line scheduling and the overhead of dynamic approaches such as earliest-deadline scheduling.
- read someone the riot act — If someone in authority reads you the riot act, they tell you that you will be punished unless you start behaving properly.
- really simple syndication — Rich Site Summary
- saybolt universal seconds — a US measurement of viscosity similar in type to the British Redwood seconds
- single document interface — (programming) (SDI) A limitation applying to an application program that only shows a single windows giving a view of one document at a time. The opposite is Multiple Document Interface (MDI).
- spectral band replication — (audio, compression) (SBR) Guessing the nontransmitted higher frequency range of a compressed audio file by some helper bits (transmiited with the stream) and the transmitted base band. SBR allows a restoration (not reconstruction) of the upper frequency range without lots of bits. It was developed by Coding Technology, and is useful for medium and high quality coding at low and medium data rates. It is used by Digital Radio Mondiale and MP3 Pro.
- structured query language — SQL
- subscriber trunk dialling — a service by which telephone subscribers can obtain trunk calls by dialling direct without the aid of an operator
- take up the cudgels (for) — to come to the defense (of)
- tetragonal trisoctahedron — Geometry. a trisoctahedron the faces of which are quadrilaterals; trapezohedron.
- thermodynamic equilibrium — the condition of an isolated system in which the quantities that specify its properties, such as pressure, temperature, etc, all remain unchanged
- thermodynamic temperature — temperature defined in terms of the laws of thermodynamics and not in terms of the properties of any real material. It is usually expressed on the Kelvin scale
- thermoluminescence dating — a method of dating archaeological specimens, chiefly pottery, by measuring the radiation given off by ceramic materials as they are heated.
- time domain reflectometer — (hardware, networking) (TDR) An electronic device for detecting and locating short- or open-circuits in an Ethernet cable. TDRs can also measure how the characteristic impedance of a line varies along its length.
- to be in the catbird seat — to be in a very good situation
- track and field athletics — a collection of sporting events that involve running, sprinting, throwing, jumping and walking
- trading standards officer — a person who works for a trading standards office
- transcendental meditation — a technique, based on ancient Hindu writings, by which one seeks to achieve a relaxed state through regular periods of meditation during which a mantra is repeated. Abbreviation: TM.
- transcendental-philosophy — transcendental character, thought, or language.
- tribasic sodium phosphate — sodium phosphate (def 3).
- unconditional convergence — the property of a convergent infinite series that remains convergent when the terms are arranged in any order.
- under the watchful eye of — If you do something under the watchful eye of someone who has authority over you, they watch you carefully to make sure there are no problems.
- undisputed world champion — a boxer who holds the World Boxing Association, the World Boxing Council, the World Boxing Organization, and the International Boxing Federation world championship titles simultaneously
- vertical redundancy check — (storage, communications) (VRC) An error checking method performed on one 8-bit ASCII character, where the 8th bit is used as the parity bit. The resulting parity bit is constructed by XORing the word. The result is a "1" if there is an odd number of 1s, and a "0" if there is an even number of 1s in the word. This method is unreliable because if an odd number of bits are distorted, the check will not detect the error. The Longitudinal Redundancy Check is an improvement.
- war of the grand alliance — the war (1689–97) in which England, the Netherlands, Spain, Sweden, and the Holy Roman Empire in league with Bavaria, Brandenburg, Savoy, and the Palatinate opposed France.
