The boundary conditions for these equilibrium equations are more complicated than for classical lamination theory. However, they are more logical because the Kirchhoff shear force or free-edge condition, in which... 

The Hadean may not be a first choice for a vacation, but for evolution the edge condition proffers an unequaled opportunity to gain new perspectives. 

So what is the gist of all these explanations They serve to make room for a new interpretation of the fossil record. According to the new model speciation was a fait accompli when the first animals began to produce fossils. It happened even earlier, the true edge-condition for speciation must be placed at the Hadean-Precambrian transition and that means that it was a chemical and not a biological phenomenon.

Edge conditions. At the base of an analytical solution lies reviewed above advective-dispersive mass transport equation. For its solution it is necessary to have boundary and initial conditions, i.e., conditions at which the process begins, operates and ends. 

The many tests on coupons (with supported edges), and on stiffened compression panels, can reduce the residual strength by more than 70% [11]. Figure 9.6 shows the results of a series of tests by Olsson [12] conducted on panels of various thicknesses, edge conditions and materials. The decrease in residual strength with delamination width is dramatic. There is a modest increase in residual strength for the toughened epoxy (6376) and thermoplastic PEEK.

With all due respect to the metallurgical characteristics, temper, thickness, or material shape, over which the slitter has no control, the quality of the slit strand is still a function of its edge condition, accuracy of width, flatness or crosscurvature, camber, and surface finish.

If a shearing operation is involved in less than 1000 cuts a day, the rule of thumb indicates that a hydraulic shear would serve the purpose. Cuts of 4000 or more per day would justify the additional expense of a mechanical shear. The typical mechanical shear operates at approximately 60 strokes/min, whereas a hydraulic shear will average around 20 strokes/min. If a shearing operation averages 4800 cuts per day, it will take a hydraulic shear 2.3 h longer than a mechanical shear to perform the same operation. When evaluating a shear to handle 1000-4000 cuts per day, edge condition and acquisition cost must be taken into account. 

Deflection and moment coefficients for different loading and edge conditions are given in Tables 4.1 and 4.2 in the EUROCOMP ffandbook. The requisite tables, for a given loading and material description, are identified using Table 4.4. 

Exact solutions for the response for these edge conditions and under general loading conditions are not available. Equations have been derived by Whitney, [4.3] using energy methods. 

For a single and sharp obstruction, which characterizes the knife-edge condition, the diffracted field E can be calculated as a function of the radiated field Eq using the classical diffraction theory, in which case... 

Although the continuous places can be used to quantitatively represent the input-output conditions of a level-3 component, it is in general more convenient to use the deviation places to construct a qualitative model for the purpose of hazard analysis. Let us consider the fictitious relations described with the digraph presented in Fig. 5a. Here, the edge conditions ESa and ESb denote two distinct equipment states. Notice that the input-output relations under the same equipment state may be invoked according to the logic operator OR. The same relations can be expressed with the Petri net presented in Eig. 5b. Noticed also that two additional features may be introduced into this model ...
