Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Stability and instability of a generic non--conservative compressible two--fluid model
通用非保守 可压缩 双流体模型 稳定性 不稳定性
2023/5/8
We are concerned with stability and instability of the steady state (1,0, 1, 0) for a generic non–conservative compressible two–fluid model in R^3. Under the assumption that the initial fraction densi...
Rapid Approach of Integrated Survey for the Conservative Analysis of Pictures
Cultural Heritage Photogrammetry Thermal Analysis Classification Interpretation Test
2015/11/12
The survey and deep knowledge of cultural heritage and of its conservation state contribute to the definition of environmental sustainability criteria since the preservation of the cultural heritage i...

Small fluctuations epitaxial growth conservative noise
2015/10/16
We study the combined effect of growth (material deposition from above) and nearest-neighbor entropic and force-dipole interactions in a stochastically perturbed system of N line defects (steps) on a ...
Conservative homoclinic bifurcations and some applications
conservative dynamics homoclinic bifurcations Newhouse phenomena persistent tangencies Hausdorff dimension standard map three body problem Sitnikov problem
2015/9/25
We study generic unfoldings of homoclinic tangencies of two dimensional area preserving diffeomorphisms (conservative Newhouse phenomena) and show that they give rise to invariant hyperbolic sets of a...
Charter Schools in Alberta: Change or Continuity in Progressive Conservative Education Policy?
Charter School Progressive Conservative Education
2015/9/25
The Progressive Conservative government of Premier Ralph Klein undertook an ambitious program of educational restructuring. Among other changes the government provided for the establishment of charter...
Necrotising fasciitis,a potential threat following conservative treatment of a leucopenic cat:a case report

Nonlinear normal modes Stability Trigonometrification
2015/8/27
Thispaperdealswithaclassofconservative nonlinear oscillators of the form ¨ x(t) + f (x(t)) = 0,where f (x) is analytic. A transformation of time fromt to a new time coordinate τ is defined such that p...
Guaranteed Conservative Fixed Width Confidence Intervals Via Monte Carlo Sampling
Intervals Via Monte Carlo Sampling Guaranteed Conservative
2015/8/21
Monte Carlo methods are used to approximate the means, μ, of random variables
Y, whose distributions are not known explicitly. The key idea is that the average of a random
sample, Y1,...,Yn, tends t...
