https://en.wikipedia.org/wiki/Free%20boundary%20condition | In image processing, the free boundary condition is the convention used when applying a convolution kernel to a digital image in which pixel locations that lie outside the image boundaries are interpreted as having a value of zero. The question of what value to assign out-of-bounds pixels may arise, for instance, when ... |
https://en.wikipedia.org/wiki/Ulster%20Museum | The Ulster Museum, located in the Botanic Gardens in Belfast, has around 8,000 square metres (90,000 sq. ft.) of public display space, featuring material from the collections of fine art and applied art, archaeology, ethnography, treasures from the Spanish Armada, local history, numismatics, industrial archaeology, bot... |
https://en.wikipedia.org/wiki/Certified%20broadcast%20technologist | Certified Broadcast Technologist (CBT) is a title granted to an individual that successfully meets the experience or examination requirements of the certification. The certification is regulated by the Society of Broadcast Engineers (SBE). The CBT title is protected by copyright laws. Individuals who use the title with... |
https://en.wikipedia.org/wiki/Infinitesimal%20strain%20theory | In continuum mechanics, the infinitesimal strain theory is a mathematical approach to the description of the deformation of a solid body in which the displacements of the material particles are assumed to be much smaller (indeed, infinitesimally smaller) than any relevant dimension of the body; so that its geometry an... |
https://en.wikipedia.org/wiki/X17%20particle | The X17 particle is a hypothetical subatomic particle proposed by Attila Krasznahorkay and his colleagues to explain certain anomalous measurement results; these anomalous measurements are known as ATOMKI anomaly or beryllium anomaly or X17 anomaly. The particle has been proposed to explain wide angles observed in the ... |
https://en.wikipedia.org/wiki/Robotic%20sensing | Robotic sensing is a subarea of robotics science intended to provide sensing capabilities to robots. Robotic sensing provides robots with the ability to sense their environments and is typically used as feedback to enable robots to adjust their behavior based on sensed input. Robot sensing includes the ability to see, ... |
https://en.wikipedia.org/wiki/HMA%20%28VPN%29 | HMA (formerly HideMyAss!) is a VPN service founded in 2005 in the United Kingdom. It has been a subsidiary of the Czech cybersecurity company Avast since 2016.
History
HMA was created in 2005 in Norfolk, England by Jack Cator. At the time, Cator was sixteen years-old. He created HMA in order to circumvent restrictions... |
https://en.wikipedia.org/wiki/ATX | ATX (Advanced Technology Extended) is a motherboard and power supply configuration specification, patented by David Dent in 1995 at Intel, to improve on previous de facto standards like the AT design. It was the first major change in desktop computer enclosure, motherboard and power supply design in many years, improv... |
https://en.wikipedia.org/wiki/Rake%20%28cellular%20automaton%29 | A rake, in the lexicon of cellular automata, is a type of puffer train, which is an automaton that leaves behind a trail of debris. In the case of a rake, however, the debris left behind is a stream of spaceships, which are automata that "travel" by looping through a short series of iterations and end up in a new loca... |
https://en.wikipedia.org/wiki/Acoustic%20Doppler%20current%20profiler | An acoustic doppler current profiler (ADCP) is a hydroacoustic current meter similar to a sonar, used to measure water current velocities over a depth range using the Doppler effect of sound waves scattered back from particles within the water column. The term ADCP is a generic term for all acoustic current profilers, ... |
https://en.wikipedia.org/wiki/Vkernel | A virtual kernel architecture (vkernel) is an operating system virtualisation paradigm where kernel code can be compiled to run in the user space, for example, to ease debugging of various kernel-level components, in addition to general-purpose virtualisation and compartmentalisation of system resources. It is used by... |
https://en.wikipedia.org/wiki/Mass%20action%20law%20%28electronics%29 | In electronics and semiconductor physics, the law of mass action relates the concentrations of free electrons and electron holes under thermal equilibrium. It states that, under thermal equilibrium, the product of the free electron concentration and the free hole concentration is equal to a constant square of intrin... |
