Optical mark recognition (OMR) collects data from people by identifying markings on a paper.OMR enables the hourly processing of hundreds or even thousands of documents. A common application of this technology is used in exams, where students mark cells as their answer
A gas-filled tube, also commonly known as a discharge tube or formerly as a Plücker tube, is an arrangement of electrodes in a gas within an insulating, temperature-resistant envelope. Gas-filled tubes exploit phenomena related to electric discharge in gases , and operate by ionizing the gas with an applied voltage sufficient to cause ...
Capacity table for horizontal cylindrical storage tank [3] In order for volume measurements from the tank to be used, it typically has a capacity table created using appropriate standards. [3] Each row of capacity table contains fill level value and corresponding volume value (and other related data).
The fill factor of an image sensor array is the ratio of a pixel's light sensitive area to its total area. For pixels without microlenses, the fill factor is the ratio of photodiode area to total pixel area, [1] but the use of microlenses increases the effective fill factor, often to nearly 100%, by converging light from the whole pixel area into the photodiode.
For example, heat capacity is an extensive property of a system. Dividing heat capacity, , by the mass of the system gives the specific heat capacity, , which is an intensive property. When the extensive property is represented by an upper-case letter, the symbol for the corresponding intensive property is usually represented by a lower-case ...
The harmonic capacity can also be understood as a limit of the condenser capacity. To wit, let S r denote the sphere of radius r about the origin in . Since K is bounded, for sufficiently large r, S r will enclose K and (Σ, S r) will form a condenser pair. The harmonic capacity is then the limit as r tends to infinity:
For example, naturally in monocular vision at the physiological blind spot, the percept is not a hole in the visual field, but the content is “filled-in” based on information from the surrounding visual field. When a textured stimulus is presented centered on but extending beyond the region of the blind spot, a continuous texture is perceived.
The relationship between capacitance, charge, and potential difference is linear. For example, if the potential difference across a capacitor is halved, the quantity of charge stored by that capacitor will also be halved. For most applications, the farad is an impractically large unit of capacitance.
