To get a closed-form expression, we approximate the phase term m 2 Δ f d sinθ/c 0 as m Δ f d sinθ/c 0. To make the assumption reasonable, an empirical requirement can be employed: left|frac{ M-1)^{2}Deleft|frac{ M-1ta}{c_{0}}- frac{(M-1)delta f d sintheta}{c_{0}}right| le frac{pi}{4}.

The use of ontologies can contribute to perform the verification of behavioral models considering their empirical benefits for requirements engineering identified in a previous systematic literature review (Dermeval et al. 2015).
I begin by describing some of the empirical molecular design requirements that appear to be important for achieving high mobilities in these apparently comparatively poorly ordered systems: One factor that appears to be important is a coplanar backbone conformation with minimum backbone torsion and steric hindrance between the donor and acceptor conjugated units.

The disadvantage of using these types of empirical methods is the requirement of comprehensive and relevant datasets with defined geometrical characteristics.
Science
The emerging field of lipidomics faces three main analytical challenges: (i) a paucity of bioinformatic tools for spectral analysis; (ii) the need for accurate lipid prediction algorithms before experimenters can proceed to empirical validation; (iii) a requirement for visual tools capable of displaying all theoretically possible lipid conformations in 2D and 3D.

Expert writing Tips
Best practice
When using "empirical requirement", clearly state the data or observations that support the necessity of the requirement. This adds credibility and context to your statement.
Common error
Avoid using "empirical requirement" when referring to needs based on theoretical models or assumptions. "Empirical" specifically denotes observation and evidence-based needs, not those derived from theory.
