The phrase "a strict constraint" is correct and usable in written English.
It can be used when referring to a limitation or restriction that is rigid and not open to flexibility.
Example: "The project must adhere to a strict constraint regarding budget limits, which cannot be exceeded."
Alternatives: "a rigid limitation" or "a firm restriction."
The propagation of capillary waves on material interfaces between two fluids imposes a strict constraint on the numerical time-step applied to solve the equations governing this problem and is directly associated with the stability of interfacial flow simulations.
When a strict constraint on reinsurance premium budget is implemented, which often occurs in reality, the limited stop loss reinsurance is optimal, consistent with the common practice in reality.
All treatment modalities delivered approximately the same doses and the same levels of dose heterogeneity to each planning target volume (PTV), although the minimum PTV doses in the vertebral plans were substantially lower than the prescription, because of the requirement that the plans meet a strict constraint on the dose to the spinal cord and cord planning risk volume (PRV).
However the first technique imposes a strict constraint on the pulse duration of the pump laser.
Clearly, previous literatures either focus on heuristic algorithms, which remain difficult to characterize and have no performance guarantee [4 7, 18], or employ a strict constraint to reduce complexity [8, 9], which cannot be extended to accommodate the general case.
In contrast, the video flow duration is independent of the transmission rate and subject to a strict constraint so as to preserve the intrinsic time relation of the flow.
This is a more strict constraint and results in infeasible model even for much smaller topologies.
Hence, this assumption may impose a very strict constraint on the model because time delays sometimes vary dramatically with time in real circuits.
Obviously these impose a very strict constraint on the model because time delays sometimes vary dramatically with time in real models [13, 14].
In fact, the explicit presence of in Theorem 2.1 (see [5]) may impose a very strict constraint on the coefficients of (1.5) (e.g., when is very large or small).
For TrES, we require a more strict constraint on the wind mass losses, such that (dt_{mathrm{wind}} = f_{mathrm{wind}} m/dot{m}_{mathrm{wind}}), where (f_{mathrm{wind}}=0.01) and (dot{m}_{mathrm{wind}}) is the wind mass loss rate given by the stellar evolution code.
