MAF/MinorAlleleCount: C=0.1506/754 (1000 Genomes, where number of genomes sampled = N = 2504); [4] where C is the minor allele for that particular locus; 0.1506 is the frequency of the C allele (MAF), i.e. 15% within the 1000 Genomes database; and 754 is the number of times this SNP has been observed in the population of the study.
This requires the use of an alternative method of calculating airflow into the engine, which is also referred to as 'Speed-Density' system, as opposed to a MAF system. On vehicles so equipped, this alternative involves the use of a manifold absolute pressure, or MAP, sensor. The MAP sensor measures pressure in the engine's inlet manifold.
A compressor map is a chart which shows the performance of a turbomachinery compressor. This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor. A map is created from compressor rig test results or predicted by a special computer program.
For example, such a regulation might limit the concentration of NOx to 55 ppmv in a dry combustion exhaust gas corrected to 3 volume percent O 2. As another example, a regulation might limit the concentration of particulate matter to 0.1 grain per standard cubic foot (i.e., scf) of dry exhaust gas corrected to 12 volume percent CO 2.
It is a one-to-one relationship with an offset of -100 kPa for boost pressure. Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions. A MAP sensor will never display a negative reading because it is measuring absolute pressure, where zero is the total absence of pressure.
MAF (gene) Minor allele frequency in genetics; Methoxyacetylfentanyl, an opioid analgesic; Macrophage-activating factor; Moisture and Ash Free, a measure of moisture and ash content as used in ranking coals or the heat-content of wood; Million acre-foot, MAF, a unit of volume commonly used in the United States in reference to large-scale water ...
MAF sensor in a 2006-2015 automotive diesel engine. A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its ...
Typically this is applicable for applications where even the other types of MAF are unable to access or when a less viscous medium is desired. One example application of magnetic fluid finishing is silicon micropore optics, in the case of this particular optic the side walls are to be finished to <1.0 nm rms for x-ray reflection.
