There usually exist rubber materials in the outside of underwater navigators. In one aspect, sound radiation from these navigators can be reduced by the materials, and it is beneficial to control the pollution of noises in ocean environments. In the other aspect, the resistance induced by the fluid can be decreased, and it is helpful to enhance the speed of these navigators. In the paper, a numerical...
A novel simulation framework based on Service-Oriented Architecture(SOA) is proposed to meet the new requirements for simulation compos ability, this framework is open and is propitious to integration with other systems. A simulation platform is constructed using component-based software engineering to test the feasibility of SOA-based framework, the implementation of simulation service layer and...
The important factors for the development of GPS navigation system are the speed and cost of electronic map display with the mass data. It is essential to improve the speed of the electronic map information retrieval and browsing without increasing the cost. This paper presents a novel superfast image data retrieval method based on Hash function. This method simplifies the complexity of traditional...
