Each of these three groups of households was treated as an independent sub-frame, and random sampling was then used to select households within each group.
In order to administer surveys to a variety of households, the CCHS samples households by area framing, telephone list framing, and random digit dialing.
By combining the axial scanning method with 2D acousto-optic frame scanning and random-access scanning, we measured neuronal population activity of about 40 neurons across two imaging planes separated by 40 μm and achieved scan rates up to 20 30 Hz.
Incorporation of the ETL focusing system into our custom AOD-based two-photon microscope enabled fast two-layer frame-scanning and random-access scanning on a preselected set of 40 cells spread across two planes at different focal depths with sampling rates of up to 20-30 Hz.
Frames with deterministic and random residual stresses are then analysed by advanced geometric and material nonlinear analysis using the proposed scale factors to determine the influence of residual stress and its different patterns on the ultimate strength and reliability of steel frames.
These patients were selected by compiling a list of patients who visited a particular site hospital during the study time frame and using a random number generator to select the study group.
The observed variability in responses by different grades of academic staff illustrates the need, for future applications of this method of estimating effect sizes, to carefully consider the sampling frame and to use random sampling to improve the generalisability of results.
Driven by separate motors, the rotation of each frame is random and autonomous and regulated by computer software.
The size of the packet (frame) was set to 10 ms (160 samples for the wideband signal) and random packet (frame) losses were inserted by using the error insertion device (EID) in ITU-T G.191 software tool [30], which uses Gilbert and Bellcore models, with zero bit error rate and 0.5 of burst factor in which 0 and 1 indicate the totally random and burst error, respectively.
A non-linear stochastic finite element formulation for the stochastic response analysis of geometrically non-linear, elastic two-dimensional frames with random stiffness properties and random damping subject to stationary random excitations is derived, utilizing deterministic shape functions and random nodal displacements.
