Research ArticleOpen accessEvery word in the titleTwo Simple Yet Effective Strategies for Avoiding Over-Smoothing in SFS ProblemMonica Carfagni, Rocco Furferi, Lapo Governi et al.Minimization techniques are widely used for retrieving a 3D surface starting from a single shaded image i.e., for solving the shape from shading problem. Such techniques are based on the assumption that expected surface to be retrieved coincides with the one that minimize a properly developed functional, consisting of several contributions. Among the possible contributes defining the functional, the so … …Journal of Computer Science, Vol. 12, Issue 3 · 20 Apr 2016 · 8,122 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFUZZY SHRINK IMAGE DENOISING USING SMOOTHING SPLINE ESTIMATIONG.M. Rajathi, R. Rangarajan, R. Haripriya, R. NithyaThe image data is normally corrupted by additive noise during acquisition. This reduces the accuracy and reliability of any automatic analysis. For this reason, denoising methods are often applied to restore the original image. In proposed method a wavelet shrinkage algorithm based on fuzzy logic and the DT-DWT scheme is used. In particular, intra-scale dependency within wavelet coefficients is modeled … …Journal of Computer Science, Vol. 10, Issue 10 · 9 Jul 2014 · 6,681 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSMOOTHING SPLINE IN SEMIPARAMETRIC ADDITIVE REGRESSION MODEL WITH BAYESIAN APPROACHRita Diana, I. Nyoman Budiantara, Purhadi, Satwiko DarmestoSemiparametric additive regression model is a combination of parametric and nonparametric regression models. The parametric components are not linear but following a polynomial pattern, while the nonparametric components are unknown pattern and assumed to be contained in the Sobolev space. The nonparametric components can be approximated by smoothing spline functions. In the development of smoothing spline, the classical statistical approach … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 12 Jun 2013 · 7,252 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSkin Firming, Skin Smoothing, Skin Blemishes Elimination and Anti-aging Effects of Increased Protein Intake in the Form of Voandzeia hypogeal Seed MealUtoh-Nedosa Uchechukwu AnastasiaStudies on the effect of excess calorie intake on the human body showed that it resulted in accumulation of excess body fat; the darkening of the skin colour and the development of a bumpy skin. Problem statement: The present study investigated the effects of increased protein intake on the human skin and on body fat. The skin firming, skin smoothing … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 28 Dec 2011 · 7,908 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenetic Algorithms Connected Simulation with Smoothing Function for Searching Rule CurvesAnongrit Kangrang, Chavalit ChaleeraktrakoonRule curves are fundamental guidelines for operating a reservoir system. The objective of this paper is to find a suitable objective function and to propose a smoothing function constraint for searching the optimal rule curves by using genetic algorithms connected simulation model. The results show that an average water shortage is the optimal objective function for searching the optimal rule … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,482 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpline Smoothing for Multi-Response Nonparametric Regression Model in Case of Heteroscedasticity of VarianceBudi Lestari, I. Nyoman Budiantara, Sony Sunaryo, Muhammad MashuriProblem statement: Assume that data (yki, tki), k = 1,2,…, p; i = 1,2,…,nk where nk represents the number of repeated measurement of kth object follows multi-response nonparametric regression model with variances of errors are heteroscedastic. Nonparametric regression curves are unknown and assumed to be smooth which are contained in Sobolev space. Random Errors are independent and normally distributed with … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 13 Oct 2012 · 7,955 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSuppression of Instabilities and Stochastic Pulsation at Laser-Plasma Interaction by Beam SmoothingFrederick Osman, Heinrich HoraThe key problem of direct drive laser fusion is the appearance of parametric instabilities, stochastic pulsation, self-focusing (filamentation) and other anomalies. During the long years studies, the empirical and intuitively developed methods for smoothing of the laser beam were rather successful but a transparent understanding of the physics has still to be found. The first theory how the instabilities are … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 6,796 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExponential Smoothing Method of Base Flow Separation and Its Impact on Continuous Loss EstimatesGurudeo Anand Tularam, Mahbub IlaheeThe calculation of loss is vital for design flood estimation models and in order to estimate continuing loss (CL), proportional loss (PL) and volumetric runoff coefficient, the surface runoff has to be separated from the total given in a stream flow hydrograph. To obtain the volume of surface runoff from the streamflow hydrograph, baseflow separation becomes necessary and in this … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 8,484 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLinear Smoothing of Noisy Spatial Temporal SeriesValter Di Giacinto, Ian dryden, Luigi ippoliti, Luca RomagnoliThe main objective of the study is the development of a linear filter to extract the signal from a spatio-temporal series affected by measurement error. We assume that the evolution of the unobservable signal can be modelled by a space time autoregressive process. In its vectorial form, the model admits a state space representation allowing the direct application of the … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,311 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUtilization of Holt's Forecasting Model for Zakat Collection in IndonesiaAkbarizan, Muhammad Marizal, M. Soleh et al.The practice of zakat is gaining popularity in Indonesia. This development is attributed to the strong role of the government in consistently developing zakat infrastructure and the increased awareness of people to practice zakat. Despite this success, a mechanism for predicting future zakat collection has not yet been developed. This study applies Holt's exponential smoothing and Auto-Regressive Integrated Moving Average … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 22 Dec 2016 · 7,499 accessesView PDFCite
