In a practical system of commerce sites, we not only need to focus on their own functional requirements, but also need to consider many other security requirements. Security is a very important aspect. Access control occupies a vital role in a website system. To solve the problem of access control is to solve a majority of the security problem. The role-based access control model separated users and...
This paper focuses on the use of a discrete simulation tool ( Simio ) to explore simulation of casualty treatment in wartime. Through the use of Simio simulation platform, visual simulation model of casualty treatment was developed, based on analysis of the casualty treatment task and process in wartime. Then, a personnel allocation in an operating room was tested using the model developed by simulation...
Wood and bamboo are both sustainable and healthy materials for use in interior design. In addition, the surface texture and grain of wood and bamboo give them special acoustic characteristics which can play an important role in the interior acoustic design. The sound scattering properties of interior surfaces provide a good and consistent spatial distribution of sound energy. Interior wood diffusers...
To meet the needs on tower ATC simulation, one must construct immersive virtual environment including aerodrome scene. Traditionally, the virtual aerodrome scene was built with the help of 3D modeling software. It requires lots of work and domain expertise. In this paper, we propose an ontology-based approach to formalize ICAO Annex 14 and build aerodrome domain ontology for ATCT simulation task.
