Digital Equipment Corporation (DEC / d ɛ k / ⓘ), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until he was forced to resign in 1992, after the company had gone into precipitous decline.
Digital image correlation and tracking is an optical method that employs tracking and image registration techniques for accurate 2D and 3D measurements of changes in images. This method is often used to measure full-field displacement and strains , and it is widely applied in many areas of science and engineering.
CT2 is a digital FDMA system that uses time-division duplexing technology to share carrier frequencies between handsets and base stations. Features [1] [2] [3] of the system are: Standardized on 864–868 MHz; 500 frames/second (alternately base station and handset) 100 kHz carriers; 32 kbit/s ADPCM voice channel compression; 10 mW maximum ...
Digital image authentication is an issue [34] for the providers and producers of digital images such as health care organizations, law enforcement agencies, and insurance companies. There are methods emerging in forensic photography to analyze a digital image and determine if it has been altered.
The full-field monitoring capabilities of an image correlation technique allow for the measurement of strain magnitude and location on the surface of a specimen during a displacement-causing event, [10] such as PCBA during a thermal profile. These "strain maps" allow for the comparison of strain levels over full areas of interest.
Many of the techniques of digital image processing, or digital picture processing as it often was called, were developed in the 1960s, at Bell Laboratories, the Jet Propulsion Laboratory, Massachusetts Institute of Technology, University of Maryland, and a few other research facilities, with application to satellite imagery, wire-photo standards conversion, medical imaging, videophone ...
Nutmeg was founded in 2011 by Nick Hungerford (1980–2023) and William Todd. In 2019, The Economist described Nutmeg as a "hit fintech startup" and as being a client of Carta, a firm that keeps track of the stakes in companies. [6] Martin Stead left the company in 2019, following a loss of £18.6 million. Nutmeg has yet to make a profit. [7]
The sensitivity of a (digital or film) imaging system is typically described in the terms of the signal level that yields a threshold level of SNR. Industry standards define sensitivity in terms of the ISO film speed equivalent, using SNR thresholds (at average scene luminance) of 40:1 for "excellent" image quality and 10:1 for "acceptable ...
