Controlling-Vertex-Based Approach to Modeling Heterogeneous Objects
نویسندگان
چکیده
The paper deals with a novel approach to modeling heterogeneous objects. A controlling-vertex -based algorithm for materials information incorporation is proposed and constructed. In this algorithm, the controlling vertices with material information and geometrical information are selected as the gradient references first, and then the material information at any other points in the model space of the object can be calculated in interpolation manner according to the material information of the controlling vertices. The algorithm has been applied to software implementation. One-, two-, and three-dimensional examples are demonstrated to show the feasibility of the algorithm. Key-Words: Computer-aided design, heterogeneous object, modeling, materials distribution algorithm

Statistical Background Modeling Based on Velocity and Orientation of Moving Objects
Background modeling is an important step in moving object detection and tracking. In this paper, we propose a new statistical approach in which, a sequence of frames are selected according to velocity and direction of some moving objects and then an initial background is modeled, based on the detection of gray pixel's value changes. To have used this sequence of frames, no estimator or distribu...
متن کاملContext-aware Modeling for Spatio-temporal Data Transmitted from a Wireless Body Sensor Network
Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...
متن کاملA Novel Combinatorial Approach to Discrete Fracture Network Modeling in Heterogeneous Media
Fractured reservoirs contain about 85 and 90 percent of oil and gas resources respectively in Iran. A comprehensive study and investigation of fractures as the main factor affecting fluid flow or perhaps barrier seems necessary for reservoir development studies. High degrees of heterogeneity and sparseness of data have incapacitated conventional deterministic methods in fracture network modelin...
متن کاملPhysics - Based Modeling for Heterogeneous Objects
Heterogeneous objects are composed of different constituent materials. In these objects, material properties from different constituent materials are synthesized into one part. Therefore, heterogeneous objects can offer new material properties and functionalities. The task of modeling material heterogeneity (composition variation) is a critical issue in the design and fabrication of such hetero...
متن کاملRepresentation and CAD Modeling of Heterogeneous Objects
This paper presents a modeling scheme for objects containing multiple materials or functionally graded materials (FGM), i.e. heterogeneous objects. The material composition variations under this modeling scheme are controlled by some reference features termed as “grading sources”. The “grading source” gathers the type of grading, position of grading and a material grading function for controlli...
