WebGL is typically used with web browsers. In this paper, we represent a standalone WebGL execution environment, where the original WebGL source codes show the same result to those of WebGL-capable web browsers. This standalone environment enables us to run WebGL programs without web browsers and/or internet connections. Our implementation shows the same rendering results with typical web brows...

Compared with traditional distributed environment, the net-centric environment brings on more demanding challenges for information sharing with the characteristics of ultra-large scale and strong distribution, dynamic, autonomy, heterogeneity, redundancy. This paper realizes an information sharing model and a series of core services, through which provides an open, flexible and scalable informa...

importance of security and sense of peace is a one of the most important factors of urban environment. therefore, the necessity of security in urban spaces has caused the emergence of authentic theories like defensible spaces and crime prevention through environment design (cpted)*. in this paper, various literatures related to defensible space theories have been reviewed and the related keywor...

The large sizes of existing databases are rapidly increasing with time. In this environment, there is a need to help users, who are usually not familiar with SQL statements and the schema of a database, in getting the information sorted according to their relevancy. In response to this need, many researchers have introduced the capability of querying a database based on a list of keywords. A us...

In this paper a complete strategy for scene modelling from sensory data acquired in a natural environment is defined. This strategy is applied to outdoor mobile robotics and goes from environment recognition to landmark extraction. In this work, environment is understood as a specific kind of landscape, for instance prairie, forest, desert, etc. A landmark is defined as a remarkable object in t...
