We propose a wavelet based regression function estimator for the estimation of the regression function for a sequence of ?-missing random variables with a common one-dimensional probability density function. Some asymptotic properties of the proposed estimator based on block thresholding are investigated. It is found that the estimators achieve optimal minimax convergence rates over large class...

Aiming at a complex multi-block structured grid, an efficient dynamic mesh generation method is presented in this paper, which is based on radial basis functions (RBFs) and transfinite interpolation (TFI). When the object is moving, the multi-block structured grid would be changed. The fast mesh deformation is critical for numerical simulation. In this work, the dynamic mesh deformation is comp...

Block iterative methods are applied to hydrodynamic simulations of a one-dimensional (1-D) submicrometer semiconductor device. We show that block successive underrelaxation (SUR) converges with a fixed relaxation factor w = 0.13 for simulations at 300 K and w = 0.04 at 77 K . To demonstrate the robustness of the block iterative method, we present numerical simulations of a steady-state electron...

We consider time-processor optimal simulations of PRAM models on coated block meshes. A coated block mesh consists of-processor blocks and or p p p router blocks. The router blocks form a 2-dimensional or a 3-dimensional regular mesh, and the processor&memory blocks are located on the surface of the block mesh. As a generalization of the coated mesh, the 2-dimensional and 3-dimensional coated b...

In an Open-Pit Production Scheduling (OPPS) problem, the goal is to determine the mining sequence of an orebody as a block model. In this article, linear programing formulation is used to aim this goal. OPPS problem is known as an NP-hard problem, so an exact mathematical model cannot be applied to solve in the real state. Genetic Algorithm (GA) is a well-known member of evolutionary algorithms...

Nearest-neighbor queries in high-dimensional space are of high importance in various applications, especially in content-based indexing of multimedia data. For an optimization of the query processing, accurate models for estimating the query processing costs are needed. In this paper, we propose a new cost model for nearest neighbor queries in high-dimensional space, which we apply to enhance t...

Previous climatologies of blocking from this group using a one-dimensional index showed that in the Northern Hemisphere, onsets primarily occurred Pacific Ocean region, eastern Atlantic, and over continental Asia. In Southern western are two active regions for block onset. The development technologies such as Geographic Information System (GIS) visualization software mean ingesting data then re...
