The application of process computed tomography to microchannels is considered in this paper. Using the process computed tomography system in microchannel, a particle distribution image can be obtained in a multiphase flow. Based on the reconstructed image, it is easy to estimate the particle diffusion behaviors in a fluid flow. A microchannel system is designed for process computed tomography. The...
A wireless tracking and controlling the mobile robot using video capturing feature (VCF) for unmanned applications is presented. It is a wheel-based and Radio frequency (RF wireless communicated) is used for communication between controller and the robot. The available motions of the robot are forward, backward, right, left and the combination of these movements. Besides, a camera is built in the...
In this paper, the classical fractal graph - Koch curve was generated with unitary regulation of L system in visual C++, and the regular fractal graphs, fractal trees and handkerchief curves which have typical fractal characteristics were generated by changing the elements of generation. The unitary regulation of L system is intuitively expressed by computer language, it can not only help to understand...
This paper studies how computer games can be used to popularize the forestry science knowledge and proposes a method of 3D game development based on Virtools platform, which creates 3D models in 3ds max and Maya, then realizes the game functions in Virtools. This paper designs and develops a game based on 3D forest scenes which gets a better balance between knowledge and gameplay. The game enhances...
With shipping market fierce competition increasing, the traditional handling technology of bulk terminal yard can not meet the requirements of low-cost and high-efficiency. The 3D visualization technology is an important method to achieve the human-computer interaction, which can be used for improving handling efficiency and reducing operation cost of bulk terminal yard with the real time feedback...
Virtual Scene Technology is one of the important parts of VR systems. It takes charge of Vision issue in VR systems, and is the most important fact to affect the immersive of the system. There are many problems in training simulation of artillery reconnaissance radar, such as the battlefield environment isn't living, the load of assemble and disassemble is large, the training cost is high. The virtual...
A new method of B-Rep model partial matching based on topoisomerase is proposed. By extracting B-Rep information of the model, the CAD models are represented by the AAG (attribute adjacent graph). Next, the CAD models are expressed as the same topology by Euler operation. Finally, the sub-graph isomorphism approach is used to achieve the partial matching. Experimental results show that this method...
Genetic Algorithms (GA) are search and optimization algorithms and as such are used for minimizing or maximizing a given function and if possible finding its most suitable solution. They can be used for finding a solution to problems that are difficult to solve with traditional optimization techniques, including problems that are not well defined or difficult to be mathematically modeled, such as...
Group awareness information is important information for group work. It represents things such as group members' roles and responsibilities, their positions on an issue, their status, and the state of various group processes that group members know about when they work together. The group awareness information presented in this article is designed to capture group member activities and their behaviors...
This study was designed to elucidate the problem-solving skills used by frequent and infrequent Chinese video game players to negotiate impasses encountered while playing video game. All participants were instructed to think aloud while playing a video game for 20 consecutive minutes. Comments were made with thinking aloud. Findings showed that frequent players made significantly greater reference...
This paper describes an optimization strategy for steady state visual evoked potential (SSVEP)-based brain-computer interface (BCI), especially in a spelling program application. In this application, there are at least three components for implementing a complete BCI application: stimulator, signal processing, and application (spelling program). Ideally, those three components should run on different...
