The phrase "a model was modified" is correct and usable in written English.
It can be used in contexts where you are discussing changes or updates made to a model, such as in research, engineering, or data analysis.
Example: "After reviewing the initial results, we concluded that a model was modified to improve accuracy."
Alternatives: "a model was altered" or "a model was adjusted."
A biodegradation model was modified by imbedding a two-phase desorption relationship describing sequential Tenax extractions.
A biodegradation model was modified by imbedding a two-phase desorption relationship describing sequential Tenax extractions and further tested for interpreting the role of sorption in the bioavailability of pyrene as a function of particle size.
In addition, a prediction model was modified from the existing empirical models with an attempt to evaluate the carbonation risk in existing concrete structures.
A basic model was modified to predict the electrical conductivity of the plate for a wide range of graphite content.
A TRNSYS model was modified to account for variations in LDAC effectiveness with different conditions.
To better evaluate the efficacy of 5-LO Xinhibitors for pharmacological intervention, a rat model was modified to test the in vivo efficacy of 5-LO Xinhibitors.
Objective: A computer model was modified to study the impact of maternal endogenous and clinician-applied exogenous delivery loads on the contact force between the anterior fetal shoulder and the maternal symphysis pubis.
In the present work, a one dimensional model was modified to fit circular hot channel.
A dislocation barrier model was modified to describe the material behavior including dynamic strain aging and creep relaxation effects observed at high temperatures.
A generalized plasticity model was modified to better model the rockfill materials, and the interfaces between face slabs and cushions are modeled using zero-thickness interface elements that follow a hyperbolic stress strain model in the tangential direction.
