Pressure was measured indirectly as the load on the trusses of formwork support, which allows verification of the adequacy of the integral of the pressure envelopes, proposed by different authors, using a finite element model in ABAQUS.
The heart of the structure, the living quarters, is strictly interior, benefiting from the protection of redundant pressure envelopes.
The results from the Coherent Output Power, COP, and the Incoherent Output Power, IOP, analysis confirms that both pressure and envelope time series exhibit the same global and local features open the possibility of using low frequency accelerometers instead of conventional pressure transducers for monitoring and for dynamic diagnosis purposes.
The cross-correlation and the coherence function analysis between the pressure and the envelope process of the measured accelerometer signals "E", exhibit values approaching unity for frequencies ranging between 2 and 4 Hz.
While weak selective pressure on the envelope (E) protein gene of some dengue viruses is evident (19 ), the most extensive changes in virus genotypes appear to be due to recombination or to possible genetic bottlenecks (16, 17, 20 ).
The signals of arterial pressure, the spectral envelope of MCA velocity, TI, P ETCO2 and a marker signal were A/D converted at 100 Hz with NIRS data sampled at 10 Hz.
Consequently, it was found that the flexibility of the building reduces fluctuations in internal and net envelope pressures, as indicated by somewhat smaller RMS pressure coefficients relative to the case of a rigid building.
This paper describes a study on the influence of the flexibility of building envelope on pressures inside and net pressures on the roof of low-rise buildings with a dominant opening.
Do you feel pressure to push the envelope further?
This reveals that pressure signals and accelerometry envelope are related processes.
