Smoothing techniques are of major importance for the generation of surface meshes. For this reason a considerable amount of research has been spent on developing a large variety of sophisticated smoothing approaches. However, these methods either require direct access to the analytic surface description or are restricted to flat meshes in two dimensions. In particular, if no analytic surface da...

‎in this paper‎, ‎we present a novel approach for image selective smoothing by the evolution of two paired nonlinear‎ ‎partial differential equations‎. ‎the distribution coefficient in de-noising equation controls the speed of distribution‎, ‎and is‎ ‎determined by the edge-strength function‎. ‎in the previous works‎, ‎the edge-strength function depends on isotropic‎ ‎smoothing of the image‎, ‎...

In a series of seven studies, this paper examines acoustic characteristics of the spontaneous speech production of the English dative alternation (gave the book to the boy/ the boy the book) as a function of the probability of the choice between alternating constructions. Probabilistic effects on the acoustic duration were observed in the acoustic signal at the choice point (the first word that...

Competitive producers hold inventories to reduce costs of adjusting production and to reduce marketing costs by facilitating scheduling and avoiding stockouts. Using data for copper, heating oil, and lumber, I estimate these costs within a structural model of production, sales, and storage, and / study their implications for inventory and price behavior. Unlike earlier studies, this work focuse...

Non-native speakers often have difficulties with prosody; stress and intonation patterns that differ from those of native speakers can contribute to “foreign accent,” even at high proficiency levels. Although effects of a listener’s native language on the perception of prosody are well established, few studies have examined non-native prosody production. In particular, it is not known whether t...

Due to fenugreek based on different grown environment has vital differences in quality and physiological efficacy, this study focused on classification and identification of fenugreek seeds from different production areas using Fourier Transform Infrared (FT-IR) Spectroscopy coupled with cluster analysis. Chemometrics fequencies at 1800400 cm were exploited for the establishment of all chemomet...

In certain contexts, maximum entropy (ME) modeling can be viewed as maximum likelihood training for exponential models, and like other maximum likelihood methods is prone to over tting of training data. Several smoothing methods for maximum entropy models have been proposed to address this problem, but previous results do not make it clear how these smoothing methods compare with smoothing meth...

In this paper, we propose and validate a computationally efficient non-iterative domain decomposition procedure for calculating bivariate cubic L1 smoothing splines. This domain decomposition procedure involves calculating local L1 smoothing splines individually on overlapping “extended subdomains” that cover the global domain and then creating the global L1 smoothing spline by patching togethe...
