The activated sludge process (ASP) is widely used to treat both domestic and industrial wastewaters. main disadvantage of the ASP expense disposing excess sludge, which can account for between fifty sixty percent operating costs a treatment plant. We examine model in biochemical processes are represented by simplified version well known No. 1. A promising method decrease production increase bio...
Scaling and renormalization group (RG) methods are used to study parabolic equations with a small nonlinear term and find the decay exponents. The determination of decay exponents is viewed as an asymptotically self similar process that facilitates an RG approach. These RG methods are extended to higher order in the small coefficient of the nonlinearity. The RG results are verified in some case...
We investigate recurrence statistics of two-particle circular billiards. Dynamics of this billiard is generated by free-motion of two particles (with non-zero radius) inside a closed surface with piecewise smooth circular boundary in 2−D Euclidean space. Particles collide elastically against the boundary and each other, with angle of incidence equal to angle of reflection. We are interested in ...
In polarized neutron decay, the angular correlation between the neutron spin and the direction of emission of the electron is characterized by the coefficient A. Measuring A involves determining the forward-backward asymmetry of the decay beta with respect to the direction of the neutron polarization. The value of A, when combined with measurements of the neutron lifetime, determines the values...
Lp–Lq decay estimates of solutions to Cauchy problems of linear thermoelastic systems with second sound in three spatial variables are studied. By carefully analysis of the different effects of higher, middle and lower frequencies in phase space, the asymptotic behaviour of characteristic roots of coefficient matrices is obtained. Then, with the help of the information on characteristic roots a...
We give a new proof of the L2 version of Hardy’s uncertainty principle based on calculus and on its dynamical version for the heat equation. The reasonings rely on new log-convexity properties and the derivation of optimal Gaussian decay bounds for solutions to the heat equation with Gaussian decay at a future time. We extend the result to heat equations with lower order variable coefficient.
-We study the least square regression with data dependent hypothesis and coefficient regularization algorithms based on general kernel. An explicit expression of the solution of this kernel scheme is derived. Then we provide a sample error with a decay of 1 ( ) O m and estimate the approximation error in terms of some kind of K -functional. Index Terms -Least Square Regressions, Data Dependent ...
