Grid method for divergence of averages

Rates of Divergence of Nonconventional Ergodic Averages

We study the rate of growth of ergodic sums along a sequence (an) of times: SNf(x) = ∑ n≤N f(T nx). We characterize the maximal rate of growth and identify a number of sequences such as an = 2, along which the maximal rate of growth is achieved. We also return to Khintchine’s Strong Uniform Distribution Conjecture that the averages (1/N) ∑ n≤N f(nx mod 1) converge pointwise to ∫ f for integrabl...

presentation of a comparative method for grid reliability

every year, with regard to rapid development of data, grid computing that is a kind of distributed computing system is that it has attracted the attention of most people and considerably taken into account. computing that cannot be done by huge computers can be performed by grid computing. if load balance is used, efficiency will increase in grid. resources have an important and effective role ...

semi-analytical solution for static and forced vibration problems of laminated beams through smooth fundamental functions method

در این پایان نامه روش جدیدی مبتنی بر روش حل معادلات دیفرانسیل پارهای بر اساس روش توابع پایه برای حل مسایل ارتعاش اجباری واستاتیک تیرها و صفحات لایه ای ارایه شده است که می توان تفاوت این روش با روش های متداول توابع پایه را در استفاده از توابع هموار در ارضاء معادلات حاکم و شرایط مرزی دانست. در روش ارایه شده در این پایاننامه از معادله تعادل به عنوان معادله حاکم بر رفتار سیستم استفاده شده است که مو...

On Efficiency of an Unstructured Grid Generation Method for Aerospace Applications

Divergence-free WKB method.

A new semiclassical approach to the linear and nonlinear one-dimensional Schrödinger equation is presented. For both equations our zeroth-order solutions include nonperturbative quantum corrections to the WKB solution and the Thomas-Fermi solution, thereby allowing us to make uniformly converging perturbative expansions of the wave functions. Our method leads to a new quantization condition tha...
