PROOF SPACE [5 records]

Record 1 2021-02-26

English

Subject field(s)
  • Computer Mathematics
  • Information Processing (Informatics)
  • Currency and Foreign Exchange
DEF

A consensus mechanism used to prove that a miner has dedicated a sufficient amount of their physical storage to a given endeavor.

OBS

While proof of stake and proof of work methods use stake size and computing power, respectively, to determine who is able to verify a transaction, PoC methods use available storage space to do so.

French

Domaine(s)
  • Mathématiques informatiques
  • Traitement de l'information (Informatique)
  • Politique monétaire et marché des changes
CONT

La preuve de capacité, aussi appelée preuve d'espace (proof of space) ou preuve de stockage (proof of storage), est une alternative à la preuve de travail qui se base, non pas sur la dépense énergétique des machines validatrices, mais sur leur capacité à garder en mémoire des données.

Record 2 2011-12-21

English

Subject field(s)
  • Atomic Physics
  • Diagnostic Procedures (Medicine)
  • Biochemistry
DEF

Application of nanoscience and nanotechnologies techniques in the field of medicine.

CONT

Nanomedicine is the application of nanotechnology (the engineering of tiny machines) to the prevention and treatment of disease in the human body. This evolving discipline has the potential to dramatically change medical science. Established and near-future nanomedicine applications include activity monitors, chemotherapy, pacemakers, biochips, OTC [over-the-counter] tests, insulin pumps, nebulizers, needleless injectors, hearing aids, medical flow sensors and blood pressure, glucose monitoring and drug delivery systems.

CONT

The chapter on nanomedicine defines the field of nanomedicine and its objectives, keyed to the "biological existence proof" of the feasibility of nanotechnology. Several thought experiments are employed to help the reader develop an intuitive appreciation of time, space, and mechanics in the microworld, where nanorobots will be operating. The goals of biotechnology-based "molecular medicine" are carefully distinguished from the goals of nanomedicine. The evolution of the concept of nanomedicine and cell repair machines is described as the natural culmination of millennia of medical history. The limits of nanomedicine are presented, although by 20th century standards these limits appear, for the most part, quite tolerable and modest in scope. The applicability of the Hippocratic Oath in the nanomedical era is explored.

OBS

Nano is a prefix meaning one billionth (1/1,000,000,000).

Key term(s)

Domaine(s)
  • Physique atomique
  • Méthodes diagnostiques (Médecine)
  • Biochimie
DEF

Branche de la médecine concernée par l'application de la nanotechnologie dans la prévention et le traitement des maladies.

CONT

La nanotechnologie, inspirée de la biologie mais rendue possible par le concours de la physique, de la chimie et de l'électronique, s'oriente actuellement dans trois directions principales : (1) la nanomécanique visant la réalisation de «moteurs» au niveau moléculaire, (2) la nanoélectronique visant la réalisation d'ordinateurs moléculaires ou quantiques, (3) la nanomédecine visant la réalisation d'ensembles moléculaires artificiels pouvant exercer une action sur le corps humain dans des buts thérapeutiques, éventuellement de manière nanoélectronique, et des effets (nano)mécaniques ou chimiques.

OBS

[La nanomédecine] inclut la surveillance, la réparation, la construction et le contrôle des systèmes biologiques humains au niveau moléculaire, utilisant les nanodispositifs et les nanostructures.

Key term(s)
  • nano-médecine
  • nano médecine

Campo(s) temático(s)
  • Física atómica
  • Procedimientos diagnósticos (Medicina)
  • Bioquímica
DEF

[Rama de la medicina que] mediante el desarrollo y la aplicación de la nanotecnología, [pretende] mejorar el diagnóstico, tratamiento y prevención de enfermedades y lesiones traumáticas, así como preservar y mejorar la salud y calidad de vida del paciente.

CONT

La nanomedicina, aplicación de la nanotecnología en las ciencias de la salud, es la rama de la nanotecnología que se perfila como la de mayor proyección en un futuro próximo debido a sus importantes aplicaciones, especialmente diagnósticas y terapéuticas. La detección temprana de enfermedades, su tratamiento precoz personalizado y un preciso seguimiento posterior de su evolución serán posibles en los próximos años gracias a la aplicación de las herramientas nanotecnológicas que se están desarrollando actualmente. Los importantes avances en este campo podrían dar lugar a sistemas de diagnosis y tratamientos terapéuticos de mayor eficacia que los existentes, lo que redundaría en una mayor calidad de vida para el hombre.

Record 3 2005-11-08

English

Subject field(s)
  • Software
  • School Equipment
  • Plane Geometry
CONT

The geometry tutor(Anderson, Boyle, & Yoost, 1985) is built on the same basic design as the Lisp tutor. The student's activity in that case is to construct a geometry proof by successively applying geometric theorems, and the tutor compares his steps to a large knowledge base consisting of both correct and incorrect problem-solving rules. The tutor intervenes when the student applies an incorrect rule, i. e., makes illegal or useless moves in the space of possible inferences.

English

Subject field(s)
  • Artificial Intelligence
DEF

Programs that have proved theorems.

CONT

The exploration of the search space(i. e. the proof model) is managed by a theorem prover... Starting from the data representing the problem hypotheses, the prover produces... all the facts that can be deduced from the theory.

CONT

The counterexample found above was found by a heuristic filter to the theorem prover called the conjecture disprover.

English

Subject field(s)
  • Metrology and Units of Measure
CONT

A control mark as proof of verification and calibration will be applied in the appropriate free space on one of the side surfaces... A guarantee mark will also be applied on the test surface in such a position that it does not interfere with the use of the block, but will indicate that the surface has not been ground subsequently.

French

Domaine(s)
  • Unités de mesure et métrologie
CONT

Une marque de contrôle constatant la vérification et l'étalonnage sera apposée dans l'espace laissé libre à cet effet sur une des faces latérales (...). Une marque de sûreté sera de plus apposée sur la face d'essai en un emplacement tel qu'elle ne gêne pas l'utilisation du bloc mais que toutefois la face ne puisse ultérieurement être rectifiée sans que cette marque soit lésée.
