You can use it when discussing a specific definition or explanation of a concept, theory, or idea.
Example: "The scientist presented a formulation that describes the relationship between temperature and pressure in gases."
Alternatives: "a definition that outlines" or "a statement that explains".
In this paper, we develop a new boundary integral equation formulation that describes the coupled electro- and hydro-dynamics of a vesicle suspended in a viscous fluid and subjected to external flow and electric fields.
The non-linear first-principles model was implemented using the equation-based object-oriented Modelica modeling language and is based on a mathematical formulation that describes the main heat and mass transfer phenomena in this kind of facilities.
We derive a compact mathematical formulation that describes time-series of diverse memory properties.
A new algorithmic formulation that describes the development of microcracking, macrocracking and the brittle behavior of the concrete under cyclic behavior, is presented.
However, this limitation can be overcome by including a term in the rheological formulation that describes the stopping of the flow on a sloping surface (e.g. Hungr and McDougall 2009; Naef et al. 2006; Rickenmann et al. 2006).
If there is no limit to how many particles or photons you can put into a quantum system, that means the cat really is both dead and alive at once, and the act of measuring its state makes the mathematical formulation that describes it (called a wave function) "collapse" into a definite state, alive or dead.
The police have given no details of the alleged plot, but a police statement said the arrests were part of a "major operation" prompted by intelligence work, a formulation that has often been used to describe a lengthy period of surveillance, including phone-tapping, by undercover units and Britain's secret intelligence and security agencies, MI5 and MI6.
Each vaccine dose contained 5 ug of PspA5 or PspA3 alone or in the presence of 1/8 of the Human wP, wPlow, DT (Diphtheria and Tetanus and toxoids in a formulation that contains Al(OH3)) or DTPlow (described above) doses.
Echoing his 1999 autobiography, "Faith of My Fathers," Mr. McCain described Vietnam as the crucible that taught him the importance of dedication to a cause greater than himself — a formulation that became his campaign theme.
