Instrument à ventthumb|Erkencho Un instrument à vent (ou aérophone) est un instrument de musique dont le son est produit grâce aux vibrations d'une colonne d'air provoquées par le souffle d'un instrumentiste (flûte, trompette... ), d'une soufflerie mécanique (orgue, accordéon) ou d'une poche d'air (cornemuse, veuze... ). Ils sont regroupés en deux grandes familles : les bois pour lesquels le son est produit par vibration d'une anche ou à travers un biseau ; les cuivres pour lesquels le son est produit par les lèvres du musicien.
Requirements engineeringRequirements engineering (RE) is the process of defining, documenting, and maintaining requirements in the engineering design process. It is a common role in systems engineering and software engineering. The first use of the term requirements engineering was probably in 1964 in the conference paper "Maintenance, Maintainability, and System Requirements Engineering", but it did not come into general use until the late 1990s with the publication of an IEEE Computer Society tutorial in March 1997 and the establishment of a conference series on requirements engineering that has evolved into the International Requirements Engineering Conference.
Modeling and simulationModeling and simulation (M&S) is the use of models (e.g., physical, mathematical, behavioral, or logical representation of a system, entity, phenomenon, or process) as a basis for simulations to develop data utilized for managerial or technical decision making. In the computer application of modeling and simulation a computer is used to build a mathematical model which contains key parameters of the physical model. The mathematical model represents the physical model in virtual form, and conditions are applied that set up the experiment of interest.
Interventional cardiologyInterventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases. Andreas Gruentzig is considered the father of interventional cardiology after the development of angioplasty by interventional radiologist Charles Dotter. Many procedures can be performed on the heart by catheterization. This most commonly involves the insertion of a sheath into the femoral artery (but, in practice, any large peripheral artery or vein) and cannulating the heart under X-ray visualization (most commonly fluoroscopy).
Interventional neuroradiologyInterventional neuroradiology (INR) also known as neurointerventional surgery (NIS), endovascular therapy (EVT), endovascular neurosurgery, and interventional neurology is a medical subspecialty of neurosurgery, neuroradiology, intervention radiology and neurology specializing in minimally invasive image-based technologies and procedures used in diagnosis and treatment of diseases of the head, neck, and spine.
Traumatisme contondantUn traumatisme contondant, également connu sous le nom de traumatisme par objet contondant ou traumatisme non pénétrant, est un traumatisme physique ou une force d'impact sur une partie du corps, se produisant souvent lors d'un accident de la route, un coup direct, une agression, une blessure lors d'une activité sportive, et en particulier chez les personnes âgées qui tombent. Cela s'oppose au traumatisme pénétrant qui se produit lorsqu'un objet perce la peau et pénètre dans un tissu du corps, créant une plaie ouverte et une ecchymose.
Instrument de bord (aéronautique)Les instruments de bord servent à présenter à l'équipage technique toutes les informations utiles au pilotage et au fonctionnement de l'aéronef, à la navigation et aux communications avec les autres aéronefs et le contrôle aérien : thumb|Le poste de pilotage de l'Airbus A319 right|thumb|Les 4 instruments de base en T complétés par, en bas :- à gauche, « bille et indicateur de virage » (→ symétrie du vol et taux de virage) ;- à droite, « variomètre » (→ vitesse verticale, instrument gradué ici en 1000 pieds/m
Medical procedureA medical procedure is a course of action intended to achieve a result in the delivery of healthcare. A medical procedure with the intention of determining, measuring, or diagnosing a patient condition or parameter is also called a medical test. Other common kinds of procedures are therapeutic (i.e., intended to treat, cure, or restore function or structure), such as surgical and physical rehabilitation procedures. "An activity directed at or performed on an individual with the object of improving health, treating disease or injury, or making a diagnosis.
RestenosisRestenosis is the recurrence of stenosis, a narrowing of a blood vessel, leading to restricted blood flow. Restenosis usually pertains to an artery or other large blood vessel that has become narrowed, received treatment to clear the blockage and subsequently become renarrowed. This is usually restenosis of an artery, or other blood vessel, or possibly a vessel within an organ. Restenosis is a common adverse event of endovascular procedures.
Cylindre phonographiqueLe cylindre phonographique est l'ancêtre du disque. Lorsque, en décembre 1877, Thomas Edison invente le phonographe, il enregistre les sons sur un cylindre recouvert d'une feuille d'étain. Le , l'inventeur français Charles Cros avait déposé un mémoire qui préconisait cette méthode entre autres possibilités. vignette|Un cylindre de cire Edison.
