But dendrochronology, based on the science that determines the age of a tree by counting its rings, can come up with precise dating by using variations in the width of rings produced by climate changes to pinpoint the years during which the tree grew.
By using the variation-of-constant formula and the step-by-step integration method, integrating the second equation of system (4) from 0 to t for (0< t leq tau), we obtain I t)=e^{- mu_{1}+gamma)t} biggl(phi_{2}(0)+int^{t}_{0}F bigl(S(xi)phi _{2}(xi-tau)e^{(mu_{1}+gamma)xi}, dxibigr) biggr).
We establish martingale criterions for variations transversal to the gauge orbit and for Yang Mills fields using variations induced by the flow of vector fields of gradient type on the base manifold.
In this paper, a neural network-based closed access femtocell network is proposed by using the variations of receiving gains of multi-element femtocell.
The effect of ammonia concentration on the structural growth of ZnO nanostructures was examined by using several variations of ammonia additions into the reaction, namely from 30 to 300 μL.
Furthermore, by using the variations of parameters formula, we can write the solution of the initial boundary value problem (3) as follows: v ( x, t ) = T ( t ) v ( x, 0 ) + ∫ 0 t T ( t − s ) ( a ( x, s ) ( v ( x, s ) + ψ 0 ( 1 − x ) + ψ 1 x ) ) d s.
The results are compared to those analytically obtained by using linear variations of ionic concentrations inside the membrane.
By using other variations of this technique, one can record the ion flow through a single ion channel protein.
Color it by using different variations of green such as yellow green and forest green.
We introduce a new Sturm-Liouville problem with discontinuities which are defined depending on a parameter in the neighborhood of an interior point of θ. ε is a parameter controlling the variation of the neighborhood process and by using the variation of this parameter, it is possible to determine points of discontinuity.
