This is generally believed to be a result of the dissociation of primary cells from their native three-dimensional structure in vivo to their two-dimensional propagation on flat impermeable substrates in vitro [ 5– 7].
To ensure flat crack propagation mode, therefore, J b ′ must exceed J tip, or J_{b}^ > J_{tip} (5 Equation (5) represents the energy criterion for multiple cracking.
This is the steady state flat crack propagation mode in which crack opening is uniform at δ ss except for a small region behind the crack tip.
The computed σ relation of fly ash-based SHGCs satisfied the necessary micromechanics-based conditions of steady-state flat crack propagation, which result in strain-hardening behavior.
The crack-bridging relation of the developed composite, computed via a micromechanics-based model, satisfied the necessary strength and energy-based conditions of steady-state flat crack propagation, which result in sequential development of multiple cracking.
This flat crack propagation mode requires a balance of energy so that the work done due to applied tensile load σ ss on the body must equate to the energy required to break down the crack tip material J tip and the energy required to open the crack against fiber bridging from 0 to δ ss.
In this ideal case, flat-earth propagation is assumed, i.e. at a distance d from an emitter of power Ptx, the received power is given by P rx = P tx − L ( d 0 ) − 10 α log d d 0 (5).
In this idealised example, the flat-earth propagation model is used to determine the ground truth, using pathloss exponent α=3 in (6). Figure 2 Results of Dempster-Shafer analysis for ideal case.
Adiabatic burning velocities of premixed flat flames and propagation speeds of adiabatic cellular flames of mixtures of ethane+oxygen+carbon dioxide are reported.
The proposed algorithm is site adaptive since it makes use of the predicted influence of the ground on near-grazing propagation over flat, continuous ground surfaces and of the predicted influence of a stable refracting atmosphere.
