Magnetic resonance fingerprinting (MRF) is methodology in quantitative magnetic resonance imaging (MRI) characterized by a pseudo-randomized acquisition strategy. It involves creating unique signal patterns or 'fingerprints' for different materials or tissues after which a pattern recognition algorithm matches these fingerprints with a predefined dictionary of expected signal patterns.
A materials recovery facility for the recycling of domestic waste Clean materials recovery facility recycling video. A materials recovery facility, materials reclamation facility, materials recycling facility or multi re-use facility (MRF, pronounced "murf") is a specialized waste sorting and recycling system [1] that receives, separates and prepares recyclable materials for marketing to end ...
Magnetorheological finishing (MRF) is a precision surface finishing technology. Optical surfaces are polished in a computer -controlled magnetorheological (MR) finishing slurry. Unlike conventional rigid lap polishing , the MR fluid's shape and stiffness can be magnetically manipulated and controlled in real time .
In a typical MRF finishing setup the MRF fluid is pumped onto a rotating wheel which is connected to an electromagnet. When the electromagnet is activated the fluid transitions to a more viscous state, the workpiece is then pressed onto the fluid resulting a shearing of the fluid which results in material removal at the interface between the ...
A magnetorheological fluid (MR fluid, or MRF) is a type of smart fluid in a carrier fluid, usually a type of oil. When subjected to a magnetic field , the fluid greatly increases its apparent viscosity , to the point of becoming a viscoelastic solid. [ 1 ]
MRF-based dampers are excellent candidates for stability augmentation of the lead-lag (in-plane bending) mode of rotor blades in helicopters. [12] MRF-based squeeze film dampers are being designed for use in the rotary wing industry to isolate vibrations from the aircraft structure and crew.
The MRF's next goal is to achieve a machine capable of one exaflop (10 18 floating-point operations per second) and then one zetaflop (10 21). To achieve an exaflop machine by 2018, the NSA has proposed constructing two connecting buildings, totaling 260,000 square feet (24,000 m 2), called the Multiprogram Computational Data Center. The ...
The word technology can also mean the products resulting from such efforts, [2] [3] including both tangible tools such as utensils or machines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life. Technological advancements have led to significant changes in society.
