To facilitate applications such as environment detection or disaster monitoring, the development of rapid low cost systems for collecting near real time spatial information is very critical. Rapid spatial information collection has become an emerging trend for remote sensing and mapping applications. In this study, a fixed-wing Unmanned Aerial Vehicle (UAV)-based spatial information acquisition...

Earth observation satellites with various spatial, spectral and temporal resolutions provide an invaluable means for mapping and monitoring the Earth’s environments. With the increasing demand of satellite images for remote and harsh environments and nature disaster areas such as earthquake, flooding, bushfires and other emergent events, quickly geo-positioning those images without using ground...

• Timing decision is made for relief pre-positioning in disasters with prior warning. The impacts of timing on the cost and operation's speed are investigated. Using a graph-theoretic conversion, developed model implemented real data. Tradeoffs between logistics extracted. best different types decision-makers suggested. This research analyzes impact post-warning pre-disaster stock prepositionin...

We describe an interaction-free method for a geometric pre-positioning of virtual cloth patterns with human 3D scans. Combined with the following physically based sewing simulation, a fully automated dressing of virtual humans becomes possible. This reduces the time needed for dressing virtual humans by eliminating the time needed for the interactive placement of the cloth patterns in previous ...

In this paper, the problem of achieving high accuracy positioning of a medical robot is studied. The Northeast Proton Therapy Center, at the Massachusetts General Hospital, is a new cancer research and treatment facility. A major component of the center is a robotic patient positioning system that will carry and position patients in a proton beam. The desired positioning accuracy of the robot i...

Pervasive positioning provides uninterrupted positional information in both indoor and outdoor locations for a wide spectrum of location based service (LBS) applications. With the rapid enlargement of the low-cost and high speed data communication, Wi-Fi networks in many metropolitan cities, strength of signals broadcasted from the Wi-Fi access points (APs) namely received signal strength (RSS)...

This paper proposes a cooperative real-time positioning system to solve both indoor and outdoor location tracking problem for disaster aid, we conduct a detailed overview of pre-existing indoor positioning systems, give architecture of cooperative positioning system, and introduce the least square method to improve accuracy of time difference of arrival (TDOA) positioning algorithm. Meanwhile, ...

The atmosphere in low latitude regions is of particular interest to GPS researchers because the propagation of GPS signals becomes significantly delayed compared with other regions of the world. Hence this limits GPS positioning accuracy in equatorial regions. Although the atmospheric delay can be modelled, a residual component will still remain. Reducing, or mitigating the effect of residual a...

In the last few years, the scientific community has witnessed an ongoing trend of using ideas developed in the study of complex networks to analyze climate dynamics. This powerful combination, usually called climate networks, can be used to uncover non-trivial patterns of weather changes throughout the years. Here we investigate the temperature network of the North American region and show that...
