This paper present our color constancy investigation in the hybridization of Wireless LAN and Camera positioning in the mobile phone. Five typical color constancy schemes are analyzed in different location environment. The results can be used to combine with RF signals from Wireless LAN positioning by using model fitting approach in order to establish absolute positioning output. There is no co...

Statistical Terminal Assisted Mobile Positioning (STAMP) is a methodology that improves the accuracy of existing positioning techniques by exploiting measurements collected at the terminal side. STAMP is setting a unified positioning framework, in which different types of raw network related measurements are employed by multiple positioning techniques in order to derive coarse position estimate...

OBJECTIVE The survival benefit of prone positioning during mechanical ventilation for acute respiratory distress syndrome has been a matter of debate. Recent multicenter randomized controlled trials have shown a significant reduction of 28-day and 90-day mortality associated with prone positioning during mechanical ventilation for severe acute respiratory distress syndrome. We performed an up-t...

Radio frequency identification (RFID) technology was originally invented for military uses. From 1980s, commercial RFID products started to be available and they were mainly applied in areas of supply chains, transport, manufacturing, personnel access, animal tagging, toll collection etc. Nowadays, RFID has been recognised as an emerging technology for ubiquitous positioning (UP), especially in...

background: while various radiographic parameters and application of manual/gravity stress have been proposed to elucidate instability for weber b fibula fractures, the prognostic capability of these modalities remains unclear. determination of anatomic positioning of the mortise is paramount. we propose a novel view, the gravity reduction view (grv), which helps elucidate non-anatomic position...

Location-based service is one of the most popular buzzwords in the field of U-cities. Positioning a user is an essential ingredient of a location-based system in a U-city. For outdoor positioning, GPS based practical solutions have been introduced. However, the measurement error of GPS is too big for it to be used for U-campus services, because the size of a campus is smaller than that of a cit...

This study examined the legibility of information presented on head-up displays (HUDs) for automotive application as a function of background scene complexity, the position of the HUD within field of view relative to the background scene, and the perceptual capacity of the perceiver. Groups of field-dependent and field-independent subjects viewed video footage from the perspective of following ...
