https://en.wikipedia.org/wiki/Spread-spectrum%20time-domain%20reflectometry | Spread-spectrum time-domain reflectometry (SSTDR) is a measurement technique to identify faults, usually in electrical wires, by observing reflected spread spectrum signals. This type of time-domain reflectometry can be used in various high-noise and live environments. Additionally, SSTDR systems have the additional be... |
https://en.wikipedia.org/wiki/Combustion%20models%20for%20CFD | Combustion models for CFD refers to combustion models for computational fluid dynamics. Combustion is defined as a chemical reaction in which a hydrocarbon fuel reacts with an oxidant to form products, accompanied with the release of energy in the form of heat. Being the integral part of various engineering application... |
https://en.wikipedia.org/wiki/Import%20ratio | Import ratio, in economics and government finance, is the ratio of total imports of a country to that country’s total foreign exchange (FX) reserves. The ratio can be inverted and is referred to as the reserves to imports ratio. This ratio divides a country's average foreign exchange reserve by a country's average mont... |

https://en.wikipedia.org/wiki/NP-completeness | In computational complexity theory, a problem is NP-complete when:
It is a decision problem, meaning that for any input to the problem, the output is either "yes" or "no".
When the answer is "yes", this can be demonstrated through the existence of a short (polynomial length) solution.
The correctness of each solutio... |
https://en.wikipedia.org/wiki/Partial%20discharge | In electrical engineering, partial discharge (PD) is a localized dielectric breakdown (DB) (which does not completely bridge the space between the two conductors) of a small portion of a solid or fluid electrical insulation (EI) system under high voltage (HV) stress.
While a corona discharge (CD) is usually revealed... |
https://en.wikipedia.org/wiki/Huntington%27s%20disease | Huntington's disease (HD), also known as Huntington's chorea, is an incurable neurodegenerative disease that is mostly inherited. The earliest symptoms are often subtle problems with mood or mental/psychiatric abilities. A general lack of coordination and an unsteady gait often follow. It is also a basal ganglia diseas... |
https://en.wikipedia.org/wiki/Comparison%20of%20programming%20languages%20%28string%20functions%29 | String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).
Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly. In ob... |
https://en.wikipedia.org/wiki/Material%20flow%20management | Material flow management (MFM) is a method of efficiently managing materials.
The triad of environmental, social and economical orientation makes MFM a tool of high importance in the field of sustainable development and circular economy.
Seen historically, material flow management is a tool that can be understood as... |

https://en.wikipedia.org/wiki/Data%20virtualization | Data virtualization is an approach to data management that allows an application to retrieve and manipulate data without requiring technical details about the data, such as how it is formatted at source, or where it is physically located, and can provide a single customer view (or single view of any other entity) of th... |
https://en.wikipedia.org/wiki/Double%20harmonic%20scale | The double harmonic major scale is a musical scale with a flattened second and sixth degree. This is also known as Mayamalavagowla, Bhairav Raga, Byzantine scale, Arabic (Hijaz Kar), and Gypsy major. It can be likened to a gypsy scale because of the diminished step between the 1st and 2nd degrees. Arabic scale may also... |
