Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
A fault indicator is a mechanism that conveys an indication of a fault, or absence of it, in a system. For example, the purpose of the engine-check light commonly found on the dashboard of motor vehicles is to indicate whether or not there is a fault with the engine.
Failure analysis is the process of collecting and analyzing data to determine the cause of a failure, often with the goal of determining corrective actions or liability.. According to Bloch and Geitner, ”machinery failures reveal a reaction chain of cause and effect… usually a deficiency commonly referred to as the symptom…”
Ecological indicator of ecosystem health (ecological processes) Health indicator, which is used to describe the health of a population; Honeyguides, also known as "indicator birds", a family of Old World tropical birds Indicator, a genus of birds in the honeyguide family; Indicator species, a species that defines a characteristic of an environment
Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
A complexometric indicator is an ionochromic dye that undergoes a definite color change in presence of specific metal ions. [1] It forms a weak complex with the ions present in the solution, which has a significantly different color from the form existing outside the complex. Complexometric indicators are also known as pM indicators. [2]
In crystallography, a stacking fault is a planar defect that can occur in crystalline materials. [ 1 ] [ 2 ] Crystalline materials form repeating patterns of layers of atoms. Errors can occur in the sequence of these layers and are known as stacking faults.
