چکیده

The design of an extensible system is discussed in which the behavior of physical objects is simulated from their models. Complex objects can be defined in a multiplicity of domains. including their geometric shape, their dynamic response to applied forces. and their controlled behavior. In response to unforeseen changes, e.g., for unexpected collisions, the object models are modified automatically during the simulation. 1 Supported in part by National Science Foundation Grants ECS 83-12096.

Investigation of thermal behavior of traditional geometric patterns (khavoon chini) in the external hollow walls of Dezful double-walled walls in order to revive cultural identity

Abstract Traditional geometric patterns in architecture and decoration are rooted in the cultural identity of each region and in cities such as Dezful, they display its special cultural and identity characteristics. In Dezful, the geometric patterns of the bricks, known as the khavoon chini are one of the hallmarks of the citychr('39')s cultural identity. Due to the hot climate of Dezful, the ...

Adsorption of Fe (II) from Aqueous Phase by Chitosan: Application of Physical Models and Artificial Neural Network for Prediction of Breakthrough

Removal of Fe (II) from aqueous media was investigated using chitosan as the adsorbent in both batch and continuous systems. Batch experiments were carried out at initial concentration range of 10-50 mg/L and temperature range of 20–40˚C. In batch experiments, maximum adsorption capacity of 28.7 mg/g and removal efficiency of 93% were obtained. Adsorption equilibrium data were well-fitted with ...

Target detection Bridge Modelling using Point Cloud Segmentation Obtained from Photogrameric UAV

In recent years, great efforts have been made to generate 3D models of urban structures in photogrammetry and remote sensing. 3D reconstruction of the bridge, as one of the most important urban structures in transportation systems, has been neglected because of its geometric and structural complexity. Due to the UAV technology development in spatial data acquisition, in this study, the point cl...

Port-Hamiltonian systems: an introductory survey

The theory of port-Hamiltonian systems provides a framework for the geometric description of network models of physical systems. It turns out that port-based network models of physical systems immediately lend themselves to a Hamiltonian description. While the usual geometric approach to Hamiltonian systems is based on the canonical symplectic structure of the phase space or on a Poisson struct...
