ABSTRACT The main result of this study is that Lusatia, as an energy transition and structural change region, still has high expansion potential for photovoltaic and wind energy systems. In 2040...
ABSTRACT In compressed air energy storage systems, throttle valves that are used to stabilize the air storage equipment pressure can cause significant exergy losses, which can be effectively imp...
ABSTRACT Motivated by the water pollution detection, this paper studies a nonlinear filtering problem over an infinite time interval. The signal to be estimated, which indicates the concentratio...
ABSTRACT This paper is devoted to understanding the stability of perturbations around the hydrostatic equilibrium of the Boussinesq system in order to gain insight into certain atmospheric and o...
ABSTRACT In this paper, the study of gradient regularity for solutions of a class of elliptic problems of p-Laplace type is offered. In particular, we prove a global result concerning Lorentz-Mo...
ABSTRACT For singularly perturbed convection-diffusion problems, supercloseness analysis of the finite element method is still open on Bakhvalov-type meshes, especially in the case of 2D. The di...
ABSTRACT In this paper, we investigate sufficient and necessary conditions such that generalized Forelli-Rudin type operators Tλ,τ,k, Sλ,τ,k, Qλ,τ,k and Rλ,τ,k are bounded between Lebesg...
ABSTRACT The problem of estimating the change point in a sequence of independent observations is considered. Hinkley (1970) demonstrated that the maximum likelihood estimate of the change point ...
ABSTRACT This paper is devoted to studying the stability of transonic shock solutions to the Euler-Poisson system in a one-dimensional nozzle of finite length. The background charge in the Poiss...
ABSTRACT In this paper, some refinements of norm equalities and inequalities of combination of two orthogonal projections are established. We use certain norm inequalities for positive contracti...
ABSTRACT In this work, we propose a low-regularity Fourier integrator with almost mass conservation to solve the Davey-Stewartson II system (hyperbolic-elliptic case). Arbitrary order mass conve...
ABSTRACT In this article, we first establish an asymptotically sharp result on the higher order Fréchet derivatives for bounded holomorphic mappings (f(x) = f(0) + sumlimits_{s = 1}^infty {{{{D...
ABSTRACT Fractional calculus has drawn more attentions of mathematicians and engineers in recent years. A lot of new fractional operators were used to handle various practical problems. In this ...
ABSTRACT For each real number x ∈ (0, 1), let denote its continued fraction expansion. We study the convergence exponent defined by $$tau (x): = inf left{{s ge 0:sumlimits_{n = 1}^infty {{{le...
ABSTRACT In recent years, the direction has turned to non-stationary time series. Here the situation is more complicated: it is often unclear how to set down a meaningful asymptotic for non-stat...
ABSTRACT Estimating parameters of drift and diffusion coefficients for multidimensional stochastic delay equations with small noise are considered. The delay structure is written as an integral ...
ABSTRACT We propose a nonparametric estimation of random effects from the following fractional diffusions (dX^{j}(t) = psi _{j}X^{j}(t)d t+X^{j}(t)d W^{H,j}(t), ) (~X^j(0)=x^j_0,~tge 0, ) ( j=1,...
ABSTRACT In this paper, we propose an estimator for the Ornstein–Uhlenbeck parameters based on observations of its supremum. We derive an analytic expression for the supremum density. Making u...
ABSTRACT This paper deals with a Skorokhod’s integral based projection type estimator ({widehat{b}}_m) of the drift function (b_0) computed from (Nin mathbb N^*) independent copies (X^1,dots ,...
ABSTRACT In this paper, we are concerned with the existence of multiple solutions to the critical magnetic Schrödinger equation (0.1)$$(-{rm i}nabla-A(x))^2u+lambda V(x)u=mu vert uvert ^{p-2}u+...
