This article has described the process for tooth alignment using 3D thin plate spline. First step is to simulate the individual tooth and its landmarks and fit it into the dental cast by geometric transformation of individual tooth. Next step is to align the simulated teeth into proper arch form. After that, record pairs the landmarks of simulated teeth before and after tooth alignment. The fin...

population aged > 50 years have renal cysts [5]. Most cysts are benign and asymptomatic. A palpable mass, pain from haemorrhage into the cyst, obstructive symptoms and infections are rare presentations. A simple cyst is a fluid-filled, non-neoplastic lesion; most are unilocular, contain straw-coloured fluid, arise from the cortex and are smooth-walled. On CT they are sharply marginated, round, ...

By coupling the flexibility of Thin-Plate Splines interpolation with Green’s integral formula, we obtain a meshless cubature method from scattered samples of small/moderate size, on convex as well as nonconvex and even multiply connected polygonal domains. 2000 AMS subject classification: 65D05, 65D32.

In this paper, we present an automatic face authentication system. Accurate segmentation of prominent facial features is accomplished by means of an extension of the Active Shape Model (ASM) approach, the so-called Active Shape Model with Invariant Optimal Features (IOF-ASM). Once the face has been segmented, a pose correction step is applied, so that frontal face images are synthesized. For th...

The purpose of this study is to investigate the effects hole/holes on stress concentrations in a plate using current industry standard software - Finite Element Analysis (FEA). Plate with common engineering application such as automobile, marine, aerospace and mechanical structures. Hole/Holes can be seen many thin-walled automobile structures components. For example, are found residential/comm...

In this article, element free Galerkin method is used for static analysis of thin micro/nanoscale plates based on the nonlocal plate theory. The problem is solved for the plates with arbitrary boundary conditions. Since shape functions of the element free Galerkin method do not satisfy the Kronecker’s delta property, the penalty method is used to impose the essential boundary conditions. Discre...

A rapid and simple method has been developed for the screening and identification of natural antioxidants from the leaves of Acer ginnala Maxim.( AG). The process is that upon reaction with 1,1-diphenyl-2-picrylhydrazyl (DPPH), the white yellow spots of compounds with potential antioxidant effects will be significantly observed on the thin-layer chromatography (TLC), and possible structures wil...

The porous structures are widely designed in coastal and ocean engineering to reduce the wave load. A macroscopic CFD approach is established study interaction with a plate placed front of solid wall. numerical tank was firstly validated by analytical results vertical wall, model experimental single plate. Then load reduction effect wall investigated, influences porosity relative gap width comp...
