Comparison of ionospheric scintillation models with experimental data for satellite navigation applications
ionospheric scintillations scintillation models GPS SBAS
2015/9/10
A comparison between two of the most used scintillation models and experimental data is presented. The experimental
data have been derived from a GPS scintillation monitor developed at Cornell Univer...
Direct recordings of grid-like neuronal activity in human spatial navigation
Direct recordings grid-like neuronal activity human spatial navigation
2015/7/10
Grid cells in the entorhinal cortex appear to represent spatial location via a triangular coordinate system. Such cells, which have been identified in rats, bats and monkeys, are believed to support a...
Seamount Discovery Tool Aids Navigation to Uncharted Seafloor Features
Seamount Tool Aids Navigation Uncharted Seafloor
2015/7/7
Wessel et al. (2010) highlight the need for a systematic mapping of seamounts in ocean basins. They estimate that 100,000 or 90% of the seamounts greater than 1-km tall are unobserved by either ship s...

Cartography database generalization
2015/7/6
Generalization is certainly one of the most important current issues in cartography, with particular emphasis being placed on its
automation. This paper considers the automation of generalization app...
Wave Navigation in The Marshall Islands:Comparing Indigenous and Western Scientific Knowledge of the Ocean
Wave Navigation in The Marshall Islands Comparing Indigenous Western Scientific Knowledge the Ocean
2015/7/3
Pacific seafarers developed indigenous navigational techniques to voyage between islands. In the Marshall Islands, navigators remotely sense land by detecting how islands disrupt swells. A recent proj...

Self-assisted Amoeboid Navigation in Complex Environments
Self-assisted Amoeboid Navigation Complex Environments Cell Behavior
2011/8/18
Abstract: Background: Living cells of many types need to move in response to external stimuli in order to accomplish their functional tasks; these tasks range from wound healing to immune response to ...
Novel preference-oriented navigation system for optimal routing selection
Navigation Filter Multiple attributes Clustering
2010/9/25
The conventional navigation retrieval generally matches according to keywords and recommends information for users without considering their preferences. The ever-increasing descriptions of POIs have ...
Asymptotic of geometrical navigation on a random set of points of the plane
Asymptotic of geometrical navigation random set of points plane
2010/12/10
A navigation on a set of points is a rule for choosing which point to move to from the
present point in order to progress toward a specified target. In the present paper we study
some “geometrical b...

Sedimentation Rate Nile Delta Navigation Channel Bed Load
2013/3/6
Liquefied Natural Gas (LNG) port is located at Abu Qir Bay on the northwestern coast of the Nile delta, Egypt. The port was constructed in 2004 to export liquefied natural gas worldwide. The offshore ...
H∞ Robust Fault-Tolerant Controller Design for an Autonomous Underwater Vehicle’s Navigation Control System
AUV navigation control robust H∞ fault-tolerant control gain variations LMI
2011/9/9
In order to improve the security and reliability for autonomous underwater vehicle (AUV) navigation, an H∞ robust fault-tolerant controller was designed after analyzing variations in state-feedback ga...
A matter dominated navigation Universe in accordance with the Type Ia supernova data
navigation Universe Type Ia supernova data
2010/3/17
We investigate a matter dominated navigation cosmological model. The influence of a possible drift (wind) in the navigation cosmological model makes the spacetime geometry change from Riemannian to Fi...
