The voids at the glass frit bonding interface and inside the frit layer not only provide leakage pathways to deteriorate the sealing performance, but also reduce the effective contact area of the bonding interface to decrease the bonding strength. In this research, the micro composite glass frit bonding structure with redundant bleeding frit and bonding gap controllable was designed as the model to...

The processes of pipe collapse under external pressure have be calculated and simulated by means of the ANSYS FEA. It introduces the destruction theory of the pipe and some formula by API, and analyses the factors such as geometries, pressure, and its properties, which affect the capability of the resistance to the pipe collapse. The relationship between strain and stress of pipe has been descried...
Structure damage modelling for the simulation of elastic wave propagation is essential for simulation-based testing of structural health monitoring (SHM) systems. Reflection, transmission and other complex phenomena related to elastic wave interaction with structure defects need to be reproduced by the simulation method to replace physical testing by numerical one and aid the design process of SHM...
Kinematics design of a lower-DOF parallel robot parallel, a 3-UUR pure rotational parallel manipulator, is presented.

Simulation has become one of the dominant tools in wired and wireless network research. With the advent of cloud, grid, and cluster computing it has become feasible to use parallelization to perform richer larger-scale simulations. Moreover, the computing resources needed to perform statistically rigorous simulations are now easily obtainable. Although a number of parallel network simulation frameworks...
Simulation of variable spatiotemporal-scale forest growth is a trend in virtual forest simulation field. Most existing virtual forest simulation systems have relatively fixed structure and weak reconstruction capability. Besides, there is much duplication of work between different-granularity forest simulation systems. Therefore, this paper presents component-based forest simulation system architecture...

In simulation and computer game domains, pathfinding is an important capability for mobile and artificial agents. The problems of pathfinding have been widely studied for decades. The two significant aspect of pathfinding are related to search algorithm and search space. This paper mainly focuses on the search space generation aspect. Search space could be generated manually or automatically and the...
Developing applications and protocols for wireless sensor networks is a time consuming and error prone task, which possibly includes many iterations of implementation and testing. While simulations will probably not replace testbed experiments completely, they are a time efficient tool for rapid prototyping of sensor networks. Writing code and testing an application is often done using a different...
