Transducer

A transducer is a device that converts a physical quantity being measured into a usable output, most often an electrical signal, and is closely related to the sensor.

Transduction (genetics)

Transduction (genetics): bacteriophage-mediated transfer of bacterial DNA between cells, discovered by Zinder and Lederberg in Salmonella in 1952; generalized (random DNA packaging, P22/P1) versus specialized (prophage imprecise excision, lambda) forms.

Transductive learning

Transductive learning is a machine learning setting, introduced by Vapnik, in which a model predicts labels for one specific given test set rather than learning a general rule.

Transduodenal Sphincterotomy

Transduodenal sphincterotomy (transduodenal sphincteroplasty, TDS) is open surgical incision of the sphincter of Oddi via a duodenotomy, now reserved for failed or impossible endoscopic sphincterotomy, altered anatomy, and pancreas divisum.

TransE

TransE is a knowledge graph embedding method that represents entities and relations as vectors, scoring a triple by how well head plus relation approximates the tail.

Transect sampling

Transect sampling is a field survey method in ecology in which an observer travels along lines through a habitat, recording distances to detected organisms to estimate density.

TransEnterix Inc.

TransEnterix Inc., later known as Asensus Surgical, was a surgical robotics company in Morrisville, North Carolina, best known for the Senhance laparoscopic robot with haptic feedback.

Transesophageal echocardiography

Transesophageal echocardiography (TEE) is an ultrasound technique in which a probe in the esophagus images the heart from behind, giving sharper pictures than chest-wall scans.

Transesterification

Transesterification is an interchange reaction that converts one ester into another by exchanging its alkoxy or acyl group, best known as the central step of biodiesel production.

TRANSFAC

TRANSFAC (TRANScription FACtor database) is a commercial, manually curated database of eukaryotic transcription factors, their DNA binding sites, and PWM binding models, begun at GBF Braunschweig in 1988 and distinct from open-access JASPAR and HOCOMOCO.

Transfăgărășan

The Transfăgărășan, also called the Transfagarasan Highway, is a 151 km national road in Romania built 1970 to 1974 on Ceaușescu's orders as a military route.

Transfection

Transfection is the deliberate introduction of nucleic acids, such as DNA or mRNA, into cells by non-viral means, used in gene therapy and CAR-T cell therapy.

Transfer (association football)

Transfer (association football): the regulated movement of registered players between clubs under FIFA's RSTP, via transfer windows and TMS; shaped by the 1995 Bosman ruling, training rewards, the FIFA Clearing House, and the 2027 reform.

Transfer case

A transfer case, also called a transfer box, is a gearbox that splits a vehicle's transmission output between the front and rear axles of four-wheel-drive and all-wheel-drive vehicles.

Transfer entropy

Transfer entropy is an information-theoretic measure of directed information flow between time series, introduced by Thomas Schreiber in 2000 to detect asymmetric, possibly nonlinear coupling beyond what the target's own past explains.

Transfer function

A transfer function, also called a system function, is the ratio of the Laplace transforms of a system's output and input, used in control engineering to assess stability.

Transfer function model

The transfer function model is a time-series regression method that estimates how an input series dynamically influences an output, compressing a distributed lag into a few parameters.

Transfer hydrogenation

Transfer hydrogenation is a catalytic reduction in which hydrogen comes from a donor molecule such as isopropanol or formic acid rather than pressurized hydrogen gas, avoiding high-pressure equipment.

Transfer learning

Transfer learning, also called inductive transfer, is a machine learning framework that reuses knowledge from one task to improve learning on a different but related task, avoiding costly data labeling.

Transfer learning fault diagnosis

Transfer learning fault diagnosis is the application of transfer learning to detecting and classifying faults in machinery, most prominently rotating machines such as bearings, gearboxes, wind turbines, and electric motors.

Transfer line

A transfer line is an automated manufacturing system in which serial workstations linked by automatic transport machine large series of identical parts, most prominently automotive engine blocks and cylinder heads.

Transfer molding

Transfer molding is a manufacturing process in which a plunger forces softened thermosetting material from a heated pot through runners into a closed mold cavity, where it cures under pressure.

Transfer of capital from Delhi to Daulatabad

The transfer of capital from Delhi to Daulatabad was the move of the Delhi Sultanate's capital south, ordered by Sultan Muhammad bin Tughlaq in 1327 and reversed in 1334.

Transfer of royal burials to Nuri

The transfer of royal burials to Nuri was Taharqa's decision, around 664 BC, to found a new royal necropolis in northern Sudan, ending the sequence at el-Kurru.

Transfer of the capital of Kazakhstan to Astana

The transfer of the capital of Kazakhstan to Astana relocated the capital from Almaty to Akmola in the north-central steppe, decided by parliament in 1994 and completed on 10 December 1997.

Transfer of the capital to St Petersburg (1712)

The transfer of the capital to St Petersburg (Перенос столицы в Санкт-Петербург) was Tsar Peter I's move of Russia's capital from Moscow to St Petersburg, conventionally dated 1712.

Transfer of the Fatimid court to Egypt

The transfer of the Fatimid court to Egypt was the move of the Fatimid caliphate's capital from al-Mansuriyya in Ifriqiya to Cairo in 972–973 under caliph al-Mu'izz.

Transfer of the Isma'ili da'wa to Yemen

The transfer of the Isma'ili da'wa to Yemen moved the Musta'li Isma'ili mission's leadership from Fatimid Cairo to Yemen, where Queen Arwa appointed al-Dhu'ayb as da'i around 1132.

Transfer of the Kushite capital to Meroe

The transfer of the Kushite capital to Meroe was the shift of the Kingdom of Kush's royal residence from Napata to Meroe, conventionally placed in King Aspelta's reign around 600–580 BCE.

Transfer of the metropolitan see to Moscow

The transfer of the metropolitan see to Moscow was the 1325 move by Metropolitan Peter, at Ivan Kalita's request, of the Russian Church's seat from Vladimir to Moscow.
