However, these studies did not offer means for rigorous, theoretical derivation of the knockdown factor for the shells with generic imperfection patterns encountered in practice.
On account of various imperfections, which must occur in practice, it is said that the line of action of the resultant thrust will never coincide, with the geometrical axis of the strut.
Unfortunately, since locations of units are rarely exact in practice due to imperfections in the geocoding processes, the implementation of spatial sampling designs is actually often limited.
Geometric imperfections and residual stresses are inevitable in practice and have been so far frequently considered in analytical and numerical predictions.
In practice, fabrication errors and imperfections present.
Therefore, a PSF is observable (though in practice there will always be some noise and other imperfections), unlike the IKs.
In practice, supply and demand exhibit unpredictable dynamics and market imperfections result from asymmetrical information between graduates and employers and due to such institutions as minimum wage and limited regional mobility.
Theoretical approaches found much higher amounts of strength and stability as they assumed a perfect structure for nanotubes; while, in practice, it is almost impossible to find a CNT without structural defects and imperfections.
In practice, we must consider that sensing can also be erroneous due to inherent hardware imperfections, and consequently the usage of spectrum occupancy information obtained exclusively from local sensing might not achieve satisfactory results.
In practice, the power amplification procedure at the transmitter end will inevitably introduce the nonlinear distortion due to hardware imperfections.
