The phrase "are present to reduce" is correct and usable in written English.
It can be used in contexts where you want to indicate that something is available or exists for the purpose of decreasing or minimizing something else.
Example: "The resources are present to reduce the impact of climate change on our environment."
Alternatives: "are available to lessen" or "exist to diminish".
Novel techniques are presented to reduce noise from turbofan aircraft engines by optimising the acoustic treatment in engine ducts.
In this paper, four procedures for optimizing inductive coil design are presented to reduce computational time and lead time.
In this paper, new pixel rasterization and texture coordinate interpolation algorithms are presented to reduce silicon area.
Finally, solutions are presented to reduce the flicker produced to comply with grid code requirements in order to allow grid integration of wave farms.
Algorithms are presented to reduce the number of access points in overdimensioned networks without affecting coverage (access point selection algorithm) and to achieve a certain throughput with the least amount of access points possible (network optimization algorithm).
For the situation where such sinusoidal harmonic components are calibrated, for instance, via a priori tuning methods, simple initialization results are presented to reduce undesirable transient responses, and can be applied advantageously in a continuous-or discrete-time setting.
These results are, in our opinion, quite promising; we understand that the potential of method we are presenting to reduce the amount of time required to perform large scale electrophysiology simulations has to be further confirmed with a thorough comparison of the spectral element and the finite element methods on both the monodomain and bidomain equations.
The modulo operator is present to reduce the transmitted signal to a prescribed range, since the precoding operation may increase a given constellation point to an out-of-range value.
However, numerical results are consistent with experiments when it is speculated that sufficient internal liquid phase motion is present to reduce the effective liquid mass Peclet number to the order of one.
