The phrase "approaches of equivalent" is not correct in standard written English.
It seems to be an attempt to convey a concept related to equivalence in approaches, but it lacks clarity and proper grammatical structure.
Example: "The researchers explored various approaches of equivalent effectiveness in their study."
Alternatives: "equivalent approaches" or "approaches that are equivalent".
In this document, a novel approach of equivalent material identification is developed for multi-layered orthotropic structures.
The Egyptian code provisions for building seismic design adopt the traditional approach of equivalent static load method as the main method for evaluating seismic actions and recommend the response spectrum method for nonsymmetrical buildings.
The latest Egyptian code for load and forces (ECP 2008) and most of the international participating building codes depend on the traditional approach of equivalent static load method as the main method for evaluating seismic actions on symmetrical buildings (UBC 1997; AIJ 1999; ECS 2004; ECP 2008).
Three different approaches of the equivalent source method for simulating scattered fields are compared: two of them deal with monopole sets, the other with multipole expansions.
Bio-analytical and instrumental results can be compared by using the approach of toxicity equivalent quotients (TEQs) and biological equivalent quotients (BEQs, Van den Berg et al. [125]).
The distribution of relaxation times (DRT) method is complementary to the approach of fitting equivalent circuits because the DRT maps the EIS data onto a function containing the timescale characteristics of the system under study.
Employing unit-cell based approaches, closed-form expressions of equivalent elastic properties of regular honeycombs are available.
Likewise, in clinical trials of equivalent approaches, quality of life may be the identifying factor in determining the most "effective" treatment.
In this paper, a novel approach to the determination of Equivalent Static Wind Loads is presented.
The approach enabled the calculation of "equivalent"—with respect to cumulative fatigue failure combinations of amplitudes and numbers of internal cyclic stress.
