FUSION TECHNIQUES [9 records]

Record 1 2025-01-20

English

Subject field(s)
  • Medical Imaging
CONT

There is increasing evidence that instead of using a single imaging modality to study its relationship with physiological or cognitive features, people are paying more attention to multimodal fusion, an approach that is able to capitalize on the strength of multiple imaging techniques, since it can uncover the hidden relationships that might be missed from separate unimodal imaging studies...

French

Domaine(s)
  • Imagerie médicale
CONT

La fusion multimodale consiste à faire correspondre d'un point de vue spatial des images acquises avec des techniques différentes. Cette méthode permet d'améliorer l'information diagnostique en associant la sensibilité et la spécificité de plusieurs modalités. Le plus souvent, on souhaite superposer une image fonctionnelle (tomographie par émission de positons ou TEP, tomographie d'émission monophotonique ou TEMP, IRM [imagerie par résonance magnétique] fonctionnelle ou IRMf...) à une image anatomique (TDM [tomodensitométrie], IRM...).

Spanish

Campo(s) temático(s)
  • Radiación (Medicina)
CONT

Se utilizó una técnica de análisis de fusión multimodal que permite combinar diferentes tipos de modalidades de imágenes por resonancia magnética, lo que hace posible identificar alteraciones cerebrales más sutiles.

Record 2 2013-06-20

English

Subject field(s)
  • Information Processing (Informatics)
  • Remote Sensing
  • Cartography
DEF

A standard visualization technique for combining various geoscience datasets.

OBS

[Data] fusion is accomplished by using a number of image-processing techniques(e. g. colour space transforms, arithmetic operators, wavelet transforms), the aim of which is to produce an enhanced image suitable for visual interpretation in which the fused data compliments one another.

French

Record 3 2010-10-08

English

Subject field(s)
  • Biotechnology
  • Agricultural Engineering
DEF

A plant variety/genotype possessing characteristics that demonstrate neither familiarity nor substantial equivalence to those present in a distinct, stable population of cultivated plant species ... and that has been intentionally selected, created or introduced into a population of that species through a specific genetic change.

OBS

Plants included under this definition are plants that are produced using recombinant DNA(rDNA) techniques, chemical mutagenesis, cell fusion and conventional cross breeding.

OBS

plant with novel traits: term and definition extracted from the Plant Health Glossary of Terms of the Canadian Food Inspection Agency.

Key term(s)

Domaine(s)
  • Biotechnologie

DEF

Variété ou génotype végétal dont les caractères ne révèlent aucune correspondance ni équivalence substantielle par rapport à ceux déjà présents dans une population distincte et stable de l'espèce cultivée [...], et qui a intentionnellement été sélectionnée, créée ou introduite dans une population de cette espèce grâce à une modification génétique particulière.

Record 4 2010-03-01

English

Subject field(s)
  • Atomic Physics
  • Nuclear Fission Reactors
CONT

Improved uniformity of the laser for-al spot profile is a necessary criterion for the success of high intensity laser fusion and to improve the quality of data from moderate intensity laser driven shock experiments in solids. Recently developed laser smoothing techniques rely on both temporal smoothing and thermal smoothing to produce uniform ablation pressures on the target surface. Thermal smoothing is not effective during the low intensity portion of a laser pulse and the resultant shock structure mirrors the residual laser nonuniformities. The impact of the first(nonuniform) shock can be diminished by using foam layers, a precursor flash, shallow angles of incidence, and by adiabatically compressing the target with a temporally long, slowly rising laser pulse.

French

Domaine(s)
  • Physique atomique
  • Réacteurs nucléaires de fission
CONT

[...] il faut au départ et au cours de l'impulsion réaliser une interface aussi régulière que possible. Les irrégularités restantes ne pourront être qu'amplifiées au cours du temps (d'autres effets comme le lissage thermique viennent un peu atténuer le propos).

Record 5 2007-03-13

English

Subject field(s)
  • General Conduct of Military Operations
CONT

The use of knowledge-based systems for picture compilation, situation assessment and resource allocation has been researched in DERA [Defence Evaluation & Research Agency] over the last ten years. An important product of this research is the combat management integration support environment(CMISE) which forms the test-bed for investigation into new and improved techniques for combat management systems. CMISE is a real-time, multi-user system using a generic rulebased approach to data fusion with interfaces to operational systems enabling operation both in the laboratory and in the field.

Record 7 2000-04-25

English

Subject field(s)
  • Welding - Various Processes
CONT

Inertia welding(friction welding) has become a viable production welding method for parts having radial symmetry such as compressor drums. In this process, the metal preparation procedures are the same as for other techniques. The essence of the method is to convert rotational kinetic energy into heat to bring about controlled degrees of fusion and extrusion. Inertia welding can be done in air.

CONT

Intertia friction welding. Two workpiece parts to be joined are clamped rigidly in a sturdy fixed unit usually called the tailstock fixture and a rotating chuck assembly or collet drive. The spindle assembly, which includes one of the workpieces and any required flywheels, is rapidly accelerated to a pre-calculated speed, storing the energy required for welding. The spindle is disconnected from the drive source and begins to freewheel. At the same time, the ram assembly moves the non-rotating part axially to force both workpieces together, also a predetermined calculated (lbs.) thrust load. While the workpieces are thrust tightly together, friction between the interfaces convert kinetic energy stored in the rotating spindle and flywheel assemblies into heat at the interface, and finally into mechanical working of the plastic metals.

French

Domaine(s)
  • Procédés de soudage divers
CONT

On a coutume de distinguer deux modes de soudage selon la façon dont on exécute la friction : - le soudage par friction pilotée (FP) ou encore par entraînement direct ou conventionnel ( en anglais, continuous drive); - le soudage par friction inertielle (FI) ou encore par accumulation d'énergie (en anglais, Inertia welding, Inertia étant une marque de fabrique déposée par son inventeur). Ils donnent lieu à des assemblages identiques mais ont en pratique des domaines d'application distincts.
