Some basic aspects of dynamics and transport in polar regions within one or two scale heights of the summer mesopause are examined, and the implications for local one-dimensional photochemical modeling of those regions discussed. Included is a simple thought experiment on gravity wave breaking that throws further light on the so-called "turbulent Prandtl number" question, and related questions....

This paper proposes a method of geometric modeling of features extracted from 3D face and presents some of its applications. It describes a new automatic pose and expression invariant feature extraction algorithms to extract features (control points) from eyebrows, nose and lips of 3D facial data. The proposed algorithms are tested on BU-3DFE (Binghamton University 3D Facial Expression) Databas...

The industry of dried tofu products wants to achieve breakthrough, the key lies in developing efficient processing equipments. Pressing equipment of dried tofu has been mostly designed according to the line –“manual design (some with a CAD) prototype production prototype testing design modification". However this way not only gets a high cost of research, but also a long cycle. It used virtual ...

Subduction initiation is a critical link in the plate tectonic cycle. Intraoceanic subduction zones can form along transform faults and fracture zones, but how subduction nucleates parallel to mid-ocean ridges, as in e.g., the Neotethys Ocean during the Jurassic, remains a matter of debate. In recent years, extensional detachment faults have been widely documented adjacent to slow-spreading and...

This research aims at developing a new approach called ‘KISS Modeling’. KISS is generally a rule of ‘Keep It Simple, Stupid’ that will be applied in modeling process investigated and presented by the research. The new approach is implemented in a computer program ‘KISS Modeling’ that generates three dimensional forms based on simplifying the concept of shape recognition in design. The research,...

Modeling type Ia supernova (SN Ia) explosions in three dimensions allows to eliminate any undetermined parameters and provides predictive power to simulations. This is necessary to improve the understanding of the explosion mechanism and to settle the question of the applicability of SNe Ia in cosmological distance measurements. Since the models contain no tunable parameters, it is also possibl...

A key step in photolithography simulation is a rigorous three-dimensional modeling of the exposure/bleaching of the resist's photoactive compound (PAC). Thereby electromagnetic (EM) scattering of light caused by the nonlinear resist as well as by a nonplanar topography has to be considered. We present a novel three-dimensional approach, based on a numerical solution of the Maxwell equations. Fu...

The aim of the present study was to investigate the optimal strategy and dosimetric measurement of thoracic radiotherapy based on three-dimensional (3D) modeling of mediastinal lymph nodes (MLNs). A 3D model of MLNs was constructed from a Chinese Visible Human female dataset. Image registration and fusion between reconstructed MLNs and original chest computed tomography (CT) images was conducte...

– Quantum mechanical analysis of the quantum confinement of ultrashort CMOS is numerically very expensive. In this paper we present a macroscopic model, which includes a new approach to match the vertical carrier profile and combines it with a classical model in lateral direction. The simulation results show a significant improvement concerning the accuracy of the carrier profile and the C/V ch...

Abstract: Complex layered structures of tailings ponds and their vertical and horizontal flow conditions for the pore water require to overcome the 1 dimensional modeling of the consolidation process. A two-dimensional radial symmetric numerical model (Consol2D) based on a fully three-dimensional approach is introduced and practical results are discussed. Special attention is given to the valid...
