In this paper we develop a new approach for land leveling in order to improve the topology of a large area for irrigation or civil projects. The objective in proposed model is to minimize the total volume of cutting so that technical requirements of land leveling such as suitable slope and standard ratio of cutting to filling and maximum penstock point’s height are considered. We develop a warp...

in this paper, an interactive model for individual normal behaviour of drivers is presented in which the mutual effect of vehicles has been incorporated. temporal features obtained from vehicles tracking and their motion history is utilized for generating a model of normal behaviour. because of non-stationarity of behaviour, hidden markov model has been used for interactive model. this model ha...

A latent hardening model based on binary junction-induced hardening can effectively describe the anisotropy measured in multiaxial tests. However, this approach still has some descriptive and predictive limitations. Recent findings show that binary junctions generated by interactions of pairs of dislocations can only induce short-term hardening effect due to the unzipping process of binary junc...

Indoor evacuation model can provide scientific guidance for security solution design and emergency plan making in indoor environment, and virtual 3D scene can make the evacuation simulation more intuitive. An integration method of multi-grid evacuation model in 3D virtual indoor environment is proposed here. It maps 3D scene to 2D plane and establishes the grid table first, and then for each gr...

Plane model extraction from three-dimensional point clouds is a necessary step in many different applications such as planar object reconstruction, indoor mapping and indoor localization. Different RANdom SAmple Consensus (RANSAC)-based methods have been proposed for this purpose in recent years. In this study, we propose a novel method-based on RANSAC called Multiplane Model Estimation, which ...

Abstract This document specifies an ATM-based protocol for communication between ST2+ agents. The ST2+ over ATM protocol supports the matching of one hop in an ST2+ tree-structure stream with one ATM connection. In this docu...

An automatic three-dimensional (3D) model reconstruction technique is presented to acquire complete and closed 3D models of real objects. The technique is based on novel approaches to pose estimation and integration. Two different poses of an object are used because a single pose often hides some surfaces from a range sensor. A second pose is used to expose such surfaces to the sensor. Two part...

This paper presents a multi-feature integrated algorithm which incorporates the particle filter and LDA model for face tracking. To solve this drift problem, the discriminant model for each feature is built up by considering face and background information to separate the face from background clutter. Similar to Adaboost method, we determine the reliability of each feature by the proposed measu...

This study is based on a data set of aftershocks (location, fault−plane solutions) following the M=5.1 Arudy earthquake (02/29/80, French Western Pyrenees), and complementary geomorphological data (virtual geology using DEM and aerial photography). Data processing using Geophysical Information System are combined with identification of multi−structures based on the anisotropic wavelet formalism...

We model weak gravitational lensing of light by large-scale structure using ray tracing through N-body simulations. The method is described with particular attention paid to numerical convergence. We investigate some of the key approximations in the multi-plane ray tracing algorithm. Our simulated shear and convergence maps are used to explore how well standard assumptions about weak lensing ho...
