This paper presents a conservative front-tracking method for shocks and contact discontinuities that is second-order accurate. It is based on a volume-of-fluid method that treats the moving front with concepts similar to those of an embedded-boundary method. Special care is taken in the centering of the data to ensure the right order of accuracy at the front, and a redistribution step guarantee...
A unified approach to approximating spatial derivatives in particle methods using integral operators is presented. The approach is an extension of particle strength exchange, originally developed for treating the Laplacian in advection–diffusion problems. Kernels of high order of accuracy are constructed that can be used to approximate derivatives of any degree. A new treatment for computing de...
Difference schemes are treated as operator equations in real linear normed space [l, 23. Twoand three-layer schemes are discussed in real Hilbert space (more precisely, in unitary space, since no use is made of completeness). Stable schemes are classified. Schemes are written in a canonical form that enables stability operators, or what will be termed regularizers, to be introduced. Sufficient ...
background: the purpose of this study was to describe the knowledge and attitude of pregnant women in qazvin province, central iran, relating to oral hygiene. methods: the study group comprised of 760 pregnant women living in qazvin, center of iran in 2004. the questions were formulated to evaluate information without the need for dental examination. the age groups between 17-41 years old were ...
OBJECTIVE To determine the diagnostic accuracy of a dental computed tomographic software program, DentaScan, in assessing mandibular bone invasion in patients with squamous cell carcinoma (SCC) of the oral cavity clinically fixed to the mandible. DESIGN Retrospective chart review. SETTING Academic tertiary care medical center. PATIENTS Thirty-six consecutive patients underwent DentaScan i...
Preoperative measurement of tumor thickness of oral tongue carcinoma with intraoral ultrasonography.
BACKGROUND Tumor thickness of oral tongue carcinoma is an important independent prognostic factor for local recurrence, subclinical nodal metastasis, and survival. An accurate preoperative assessment of tumor thickness is therefore essential in optimizing treatment algorithm. The present study aims at evaluating the accuracy of intraoral ultrasonography in preoperative measurement of tumor thic...
A longitudinal study with 95 newlywed couples examined the power of the Oral History Interview to predict stable marital relationships and divorce. A principal-components analysis of the interview with the couples (Time 1) identified a latent variable, perceived marital bond, that was significant in predicting which couples would remain married or divorce within the first 5 years of their marri...
A novel spectral-element approach for the eikonal equation is presented based on the work of Tucker et al. This approach is readily implemented in standard finiteelement flow solvers developed for the Navier-Stokes equations. Results are presented for distance function (level set) for three planar configurations: circular cylinder, NACA 0012 airfoil, and T106 airfoil. Results demonstrate that t...
The paper proposes a novel multi-area state estimator based on wide area measurements where only boundary buses are considered in the coordination level. The power injection measurements are not used during the coordination level reducing the number of states and therefore size of the problem. Instead, a set of pseudo-measurements are included whenever a power injection measurement is available...
fasting is a religious obligation, which can be challenging for individuals with oral conditions due to its stringent code of conduct. moreover, food abstinence during fasting can restrict oral feeding even further in patients whose nutrition has been already compromised. previous research has mainly concentrated on oral hygiene and gum health, disregarding orodental conditions and diseases. th...
