Attenuation-to-crosstalk ratio (ACR) is a parameter that is measured when testing a communication link, which represents the overall performance of the cable. [1] AcR is a mathematical formula that calculates the ratio of attenuation to near-end crosstalk for each combination of cable pairs. [ 2 ]
The results of acute and chronic toxicity testing form the basis of knowledge that regulators draw from in performing work related to ecological risk assessment and designing policy that defines how much of a chemical of interest should be allowed in certain environments.
The Aircraft Classification Rating (ACR) - Pavement Classification Rating (PCR) method is a standardized international airport pavement rating system developed by ICAO in 2022. The method is scheduled to replace the ACN-PCN method as the official ICAO pavement rating system by November 28, 2024. [ 1 ]
Absolute Category Rating (ACR) is a test method used in quality tests. [1] [2] The levels of the scale are, sorted by quality in decreasing order: Excellent; Good; Fair; Poor; Bad; In this method, a single test condition (generally an image or a video sequence) is presented to the viewers once only. They should then give a quality rating on an ...
ACR score is a scale to measure change in rheumatoid arthritis symptoms. [1] It is named after the American College of Rheumatology . The ACR score is more often used in clinical trials than in doctor patient-relationships, as it allows a common standard between researchers.
Absolute Category Rating, a subjective quality test method; Acumulador de Carga Rápida, a battery electric tram system; Adobe Camera Raw, a raw image file converter; Advanced CANDU reactor, a nuclear reactor
Automatic content recognition (ACR) is a technology used to identify content played on a media device or presented within a media file.Devices with ACR can allow for the collection of content consumption information automatically at the screen or speaker level itself, without any user-based input or search efforts.
For example, one often uses – as a QoR component – a number representing the ratio between the area required by a combinational logic block and the area required by a simple logic gate, this number being often referred to as "relative density of combinational logic". In this case, a relative density of five will generally be accepted as a ...
