this paper presents an accurate differential global positioning system (dgps) using multi-layered neural networks (nns) based on the back propagation (bp) and imperialistic competition algorithm (ica) in order to predict the dgps corrections for accurate positioning. simulation results allowed us to optimize the nn performance in term of residual mean square error. we compare results obtained b...

The occurrence of cycle slips is a major limiting factor for achievement of sub-decimeter accuracy in positioning with GPS (Global Positioning System). In the past, several authors introduced a method based on different combinations of GPS data together with Kalman filter to solve the problem of the cycle slips. In this paper the same philosophy is used but with discrete wavelet transforms. For...

Against to the presence of high complexity, low accuracy and a smaller range of positioning in traditional positioning technologies (WLAN, RFID and visual positioning technology), it presents the multi-information fusion positioning technology. The technology takes full advantage of WLAN, RFID and visual positioning technology which chooses Kalman filter for WLAN and RFID information fusion loc...

Introduction:Tapia’s syndrome is a rare complication of recurrent laryngeal and hypoglossal nerve paralysis due to anesthetic airway mismanagement or malpositioning of the patient’s head during surgery. Case Report:Here we present a case of Tapia's syndrome in a 22-year-old male after corrective jaw surgery under general anesthesia, with a long period of recovery, related to airway management p...

Estimation of the location of a Mobile Station accurately is a key requirement to effectively provide a wide range of Location Based Services over mobile networks. Hence developing cellular positioning techniques has been a key research problem, with numerous localization solutions been proposed. These include technologies such as Cell ID, angle and time of arrival methods, statistical methods ...

Particle filter-based inertial positioning promises infrastructure-less positioning, but previous research have not provided an understanding of, how the positioning accuracy of such systems depends on the layout of building structures. This poster presents initial result for the impact of the layout of building structures on the positioning accuracy using a particle filter-based inertial posit...
