Fleet Management: A GPS-GIS Integrated Approach [ Source: GISdevelopment.net ]
January 2008-Global Positioning System (GPS) is a satellite system that provides highly accurate location with the use of special GPS receivers and their augmentations. This accurate GPS data is of limited use by itself, unless it is coupled with a powerful visualization tool like the Geographic Information Systems (GIS). The GIS is a widely accepted visualization tool that presents data in a graphic form, which is a convenient and effective means of communicating complex information.

Why Virtual Worlds Can Matter [ Source: University of Southern California ]
January 2008-Virtual worlds are persistent, avatar-based social spaces that provide players or participants with the ability to engage in long-term, joint coordinated action. This paper is an effort to outline some of the things happening in and around virtual worlds which make them more than ""just games"" and which may in fact point in the direction of new forms of knowing and acting in virtual spaces and give insight into what new, technologically mediated worlds may ....

Implementing Internet GIS With Java Based Client/Server Environment [ Source: GISdevelopment.net ]
January 2008-Data pertaining to spatial attributes in a GIS can be efficiently managed with any relational database management system (RDBMS). Java’s open, platform-independent, object-oriented design is an ideal platform for mapping and geographic information system (GIS) solution for developers. Extensible Markup Language (XML) standards can be used to describe and exchange map data between applications. It describes the salient features of a spatial database that was developed by integrating thematic layers stored as feature datasets in ....

CMOS Implementation of a 2.4-GHz Switch Mixer and Quadrature VCO [ Source: Korea Advanced Institute of Science and Technology ]
January 2008-The CMOS technology is very attractive as an RF technology because CMOS provides such advantages as low cost, high-level integration, and easy access over other technologies. Using the CMOS technology it becomes possible to integrate RF circuits, low-frequency analog circuits, and digital circuits in a single chip, which makes an ultimate one-chip system. In this manner, CMOS RF circuits are good challenges for short-range communication systems, such as Bluetooth or Wireless LAN.
