The present work concerns with an investigation on the solubility of cis,cis-muconic acid dissolution in different polar solvents by characterizing and modeling the dissolution as a function of temperature. Water, ethanol, 2-propanol and acetic acid have been investigated as solvents in the range temperatures from a 298.15 to 348.15 K. Owing to the absence of cis,cis-muconic acid solubility...

In this paper an exponentially fitted finite difference method is presented for solving singularly perturbed two-point boundary value problems with the boundary layer. A fitting factor is introduced and the model equation is discretized by a finite difference scheme on an uniform mesh. Thomas algorithm is used to solve the tri-diagonal system. The stability of the algorithm is investigated. It ...

models of curve-fitting, concept-fitting, and biomathmatical types is covered at a useful but not exhaustive level. From examples of simple linear equations to complex computer solutions, the author attempts to show how models have been used to extend the understanding of respiratory physiology beyond the limited bounds of the English language so that new information, i.e., blood gas equilibria...

The unsupervised Kohonen Networks equipped with Short Term Memory and Random Walk Breakout are used with straight-line equation as the curve fitting algorithm to predict the stock prices. According to the results obtained, the unsupervised networks do not have that high accuracy of prediction in general because of the constraint on the fixed number of patterns that they can recognize. However, ...

This paper presents a novel algorithm aiming at analysis and identification of faces viewed from different poses and illumination conditions. Face analysis from a single image is performed by recovering the shape and textures parameters of a 3D Morphable Model in an analysis-by-synthesis fashion. The shape parameters are computed from a shape error estimated by optical flow and the texture para...

In computer aided geometric design and computer graphics, high quality fair surfaces with G2 smoothness are sometimes required. In this paper we derive a general sixth order geometric partial differential equation from minimizing a curvature integral functional. The obtained equation is used to solve several surface modeling problems such as free-form surface design, surface blending and N-side...

Most Codes such as API and BSI recommend Morison’s equation to estimate hydrodynamic forces on offshore structures. Significant differences exist among these Codes due to using different methods of analysis and estimation of force coefficients. In this paper, data from full scale tests have been used to evaluate random waves and uniform current actions on the smooth piles.&#10 Four time an...

The purpose of the present study was to examine the relations among Taiwanese elementary school children’s effortful control, social relationships and their adjustment at school. Data were gathered on 407 thirdto sixth-grade children (81 third graders, 79 fourth graders, 116 fifth graders, and 131 sixth graders) attending three lowto middleclass public elementary schools in Taipei County, Taiwa...

The purpose of the present study was to investigate the relationships among sustainable behavior, study engagement, and happiness. The participants were 202 undergraduate students. The present study used structural equation modeling to examine the relationship among variables, and two models were examined. The analyses revealed that the present data best fit Model 1, in which sustainable behavi...

A mathematical model that expresses the relationship between Near-infrared light intensity and automatic threshold for automatic kiwifruit surface defect detection was established. By applying different levels of Near-infrared light intensity to machine vision system, 268 images were collected. Then the images were processed with MATLAB using the method to detect kiwifruit defects based on Near...
