The phrase "are typically generated by" is correct and usable in written English.
It can be used to describe the common source or process through which something is produced or created.
Example: "The reports are typically generated by the data analysis software used by the team."
Alternatives: "are usually produced by" or "are commonly created by".
Ultrasonic vibrations are typically generated by a piezoelectric actuator.
The silent calls are typically generated by the automatic dialling equipment used by call centre staff.
Lunar DEMs are typically generated by photogrammetry or laser altimetry approaches.
It was designed to acquire multiple channels of data with a wide dynamic range of input signals, which are typically generated by a harmonic coil and an encoder.
Advertisers that use Google keywords benefit from a 70% click-through rate, versus Yahoo!'s 18% and Microsoft MSN's 8%, according to Friedland, who said that bid management systems are able to detect and discount instances of click fraud by using software that knows how many clicks are typically generated by a keyword.
Genome-wide LOD score thresholds for QTL experiments are typically generated by permuting genotype or phenotype, re-running the mapping phase of the experiment for a large number of permutations [28], and creating an ordered list of the highest LOD score in each permutation.
Moreover, because light (transmitted as electromagnetic waves) is typically generated by electricity, which itself is usually generated by the combustion of fossil fuels, it can be said that there is a connection between light pollution and air pollution (from fossil-fueled power plant emissions).
The plasma is typically generated by radio frequency inductive coupling, microwave electron cyclotron resonance, or a DC hollow cathode magnetron.
However, there is a large amount of speckle noise in reflected- and scattered-light images, because structured illumination is typically generated by laser-beam interference.
Although that sounds perfectly clean and green, that hydrogen is typically generated by "reforming" fuels such as natural gas, gasoline, or ethanol, which invariably introduces carbon monoxide into the hydrogen gas.
Substantially more gas was generated at 50°C under anoxic conditions (75 mg C1 C5/g kerogen) than is typically generated by type II kerogen cracking at 350°C for comparable time periods: average ~5 mg C1 C5/g kerogen, non-isothermal 200 to 350°C [13]; 20 mg C1 C5/g kerogen, isothermal 350°C [10].
