Hybrid RANS/LES models, capable of transitioning through arbitrary levels modeled and resolved turbulence, aim to ameliorate both RANS deficiencies LES expense. We propose a method combining active forcing the flow field, where appropriate, with splitting standard single turbulence model into separate responsible for either unresolved stress or dissipation, which adapts that $i\phantom{\rule{0}...
We compare the ground-state features of alternating ferrimagnetic chains $(1/2,\phantom{\rule{0.28em}{0ex}}S)$ with $S=1,\phantom{\rule{0.28em}{0ex}}3/2,\phantom{\rule{0.28em}{0ex}}2,\phantom{\rule{0.28em}{0ex}}5/2$ in a magnetic field and corresponding Holstein-Primakoff bosonic models up to order $\sqrt{s/S}$, $s=1/2$, considering fully polarized magnetization as boson vacuum. The single-part...
نتیجه اصلی این مبحث یک ارتباط فرموله شده بین یک سیستم مبتنی بر قاعده rule- based و یک شبکه عصبی می باشد. بنابراین یک تئوری دامنه می تواند به یک شبکه اعمال شده، در تمام مدت بطور تجربی تجدیدنظر شده، و نهایتا" به شکل نمادی کشف رمز شود. علاوه بر این ثابت شده است که شبکه عصبی در شرایط نویزی قواعد کاراتری را نسبت به روش درخت تصمیم گیری ایجاد می کند.
this paper proposes a three-step method for solving nonlinear volterra integralequations system. the proposed method convents the system to a (3 × 3)nonlinear block system and then by solving this nonlinear system we ndapproximate solution of nonlinear volterra integral equations system. to showthe advantages of our method some numerical examples are presented.
It has been a long-standing problem in $N$-electron systems as to how solve the Dyson equation with quasiparticle wave functions defined $\ensuremath{\langle}\phantom{\rule{0.16em}{0ex}}{\mathrm{\ensuremath{\Psi}}}_{0}^{N}\phantom{\rule{0.16em}{0ex}}|\phantom{\rule{0.16em}{0ex}}{\ensuremath{\psi}}_{s}(\mathbit{r})\phantom{\rule{0.16em}{0ex}}|\phantom{\rule{0.16em}{0ex}}{\mathrm{\ensuremath{\Psi...
We report noninvasive detection of spin coherence in a collection Raman-driven cold atoms using dispersive Faraday rotation fluctuation measurements, which opens possibilities probing correlations quantum gases and other similar systems. demonstrate five orders magnitude enhancement the measured signal strength as compared to traditional noise spectroscopy with thermal equilibrium. Our observat...
