The phrase "a set of second" is not correct in English.
Did you mean "a set of seconds"? If this is the case, you can use it when referring to a collection or group of time intervals measured in seconds.
Example: "The timer recorded a set of seconds for each lap completed during the race."
Alternatives: "a collection of seconds" or "a group of seconds".
A set of second order equations with weak quadratic and cubic non-linearities is considered.
Instead, the deal would have meant marginally more trade with a set of second- and third-tier trading partners.
A set of second checks, covering the time through June, has been sent out, but figures for that mailing were not available.
A Liapunov-type technique is used to determine the response bounds for lumped vibrational systems with time-dependent parameters described by a set of second order differential equations.
The system under consideration is modelled by a set of second order differential equations and the assignment is carried by multi-input state feedback control.
Then by applying Galerkin's method, the governing equation is reduced to a set of second order non-linear differential integral equations which are solved by finite difference numerical integration procedures.
This yields a set of second-order nonlinear ordinary differential equations with coupled terms.
The Galerkin scheme is employed to discretize the two partial differential equations of motion, yielding a set of second-order nonlinear ordinary differential equations with coupled terms.
The governing equations of motion of the system are obtained employing an energy method through use of the Lagrange equations, which upon employing an assumed-mode technique, yields a set of second-order nonlinear ordinary differential equations with coupled terms.
For the given set of first-stage decision variables, a multi-objective robust optimization problem, based on an integrated business and engineering simulation model, is solved to obtain the values for a set of second-stage decision variables.
The governing partial differential equation was transformed into a set of second-order ordinary differential equations which is then numerically solved by making use of the subroutine DIVPAG from IMSL Library.
