Interviewing the patient often invalidates assumptions and reveals dimensions of a problem you didn't or couldn't anticipate because you -- the designer -- are not the patient.
Such changes to the apparatus may invalidate assumptions - most notably, within the security analysis for implementations of QKD, which could lead to exploitable side-channels.
In both figures, the NMSEs degrade, because an increase of the source interference invalidates Assumption 1. Figure 8 Comparison between SUBSS and modified SUBSS without denoising when input SNR = 10 dB: NMSE versus number of sources.
The entrepreneur launches the enterprise and works to establish it while simultaneously validating or invalidating the assumptions.
The Bayesian approach was chosen over the classical frequentionist approach, as it circumvents the problem with non-stationary noise (potentially invalidating the assumptions of Gaussian fields modelling) in multiple-comparison correction of VBM data.
Missing A1c levels were not imputed, because patients whose physicians did not order measurement of A1c levels are likely to differ in important ways from patients whose physicians did order the test, invalidating the assumptions behind missing data imputation.
However, in practice, almost all controllers have time-varying delay, hence invalidating this assumption.
This result suggests that actomyosin contractility can be the dominant force on tracer particles, thereby invalidating the assumption that particle motion is strictly under the influence of Brownian motion.
It was found that cubic volumes of railway tie dust and asphalt particles, 1.6 m and 58 m to a side, respectively, would spontaneously combust; however, compaction effects associated with asphalt softening may invalidate the assumptions of the Frank Kamenetskii spontaneous combustion theory.
An asymptotic solution in the case of film with a mobile interface gives a prediction of the surface concentration of surfactant at the centre of the film, but also predicts growing surfactant concentration gradients and growing Marangoni stresses near the film's edge, which may then invalidate model assumptions.
Future observations will either validate or invalidate the assumptions and predictions of the present work.
