PLH (H-mode power threshold) is an essential parameter in nuclear fusion. It represents the minimum power input required to trigger the transition from a low-confinement mode (L-Mode) to a high-confinement mode (H-Mode) in plasma confinement devices, such as tokamaks or stellarators. [2]
NetLogo was designed by Uri Wilensky, in the spirit of the programming language Logo, to be "low threshold and no ceiling".It teaches programming concepts using agents in the form of turtles, patches, links and the observer. [2]
- Volume rendering by high and low threshold for radiodensity. In scientific visualization , a maximum intensity projection ( MIP ) is a method for 3D data that projects in the visualization plane the voxels with maximum intensity that fall in the way of parallel rays traced from the viewpoint to the plane of projection.
Ceiling temperature is a measure of the tendency of a polymer to revert to its constituent monomers. When a polymer is at its ceiling temperature, the rate of polymerization and depolymerization of the polymer are equal.
ILS planes. An instrument landing system operates as a ground-based instrument approach system that provides precision lateral and vertical guidance to an aircraft approaching and landing on a runway, using a combination of radio signals and, in many cases, high-intensity lighting arrays to enable a safe landing during instrument meteorological conditions (IMC), such as low ceilings or reduced ...
Tsang showed that, when quantum wells are optimized, they have exceedingly low threshold current and very high efficiency in converting current-in to light-out, making them ideal for widespread use. The original 1975 demonstration of optically pumped quantum-well lasers had threshold power density of 35 kW/cm 2 .
Determining the laser threshold periodically, via a slope efficiency graph, is particularly useful in helping to determine when a laser requires refurbishment. The optimization of the laser output power for a given pump power usually involves a compromise between high slope efficiency and low threshold pump power.
This is accomplished by selecting high and low threshold values. If an edge pixel’s gradient value is higher than the high threshold value, it is marked as a strong edge pixel. If an edge pixel’s gradient value is smaller than the high threshold value and larger than the low threshold value, it is marked as a weak edge pixel.
