Skyline queries in road networks have received much attention because of their wide applications in LBS. Due to the increasing demands for services, skyline queries for moving objects in road networks which involve not only static attributes, but also dynamic ones, become more important. This paper studies a problem of how to process the continuous skyline query for moving objects in road netwo...

Greenhouse gas mitigation efforts in the electricity sector emphasize accelerated deployment of energy efficiency measures and renewable energy resources. We evaluate renewable energy (RE) and energy efficiency (EE) technologies across regional power systems in the United States in terms of carbon dioxide emissions displaced, operating costs avoided, and capacity value generated. We estimate th...

Skyline queries can filter unnecessary information efficiently and provide us important clues for various decision making tasks. Now a days, GPS devices and location based services are very popular and they can easily connect users and make groups. Conventional skyline queries are not su...
