the aim of this paper is to study the popular models used for the simulation of major elements of a water quality system. the present study compares results of the ce-qual-w2 model with the wasp5 and mike11 models to assess the water quality of pasikhan river. the contaminant loadings of nitrate and phosphate are utilized in the ce-qual-w2, wasp5 and mike11 simulations. this study is the first ...

Interactive mesh editing techniques that preserve discrete differential properties are promising to support the design of mechanical parts such as automobile sheet metal panels. However, existing methods lack the ability to manipulate form-features and hard constraints, which are common in engineering applications. In product design, some regions on a 3D model are often required to precisely pr...

This paper presents an open user modeler called the mirror modeler that pretends to be the student and solves sample questions while the student watches mimicking student errors. This ability when added to an interactive teaching environment seems to greatly facilitate the learning process for two types of mathematical series while raising a serious question about the complexity of the third.

We illustrate the basic constituents of a model and demonstrate how the facilities of Task Modeler, such as the visualization options, enable the rapid creation, analysis, and communication of the model

3D Modeling of Interior Building Environments and Objects from Noisy Sensor Suites

Object Movies (OMs) have been successfully used in many applications. However, the techniques for acquiring OMs still need to be improved if high-quality and efficient OMs are desired. In this paper, we present a method for calibrating a motorized object rig to facilitate the acquisition of OMs. We first apply the CPC kinematic model to formulate the 3D configuration of the device, and then pro...

We present results of 3D numerical modeling using a series of simple point scatterers to create synthetic seismic shot records collected over regular, discrete, vertical fracture systems. The background medium is taken to be constant velocity. The model contains a series of point scatterers delineating the top tip and bottom tip of each vertical fracture. We use these results to gain an underst...
