How does navigation system behavior influence human behavior?
Cognitive Research, 2019 Navigation systems are ubiquitous tools to assist wayfinders of the mobile information society with various navigational tasks. Whenever such systems assist with self-localization and path planning, they reduce human effort for navigating.

A Fusion Methodology to Bridge GPS Outages for INS/GPS Integrated Navigation System
IEEE Access, 2019 The performance of an inertial navigation system (INS) and global positioning system (GPS) integrated navigation system is reduced during GPS outages. To bridge GPS outages, a fusion methodology to provide pseudo GPS position information is proposed. The

Image-Based Monte-Carlo Localization With Information Allocation Logic to Mitigate Shadow Effect
IEEE Access, 2020 The development of vision-based navigation algorithms using a camera is becoming more important. The vision-based navigation can be categorized into two types. The first is to use sequential camera images as relative navigation. The second is to estimate

UKF-Based Navigation System for AUVs: Online Experimental Validation
IEEE Journal of Oceanic Engineering, 2019 Modern autonomous underwater vehicles (AUVs) are currently involved in complex tasks and scenarios, and require accurate and robust navigation systems to estimate their position. However, since the Global Positioning System cannot be exploited underwater,

RAD50 missense variants differentially affect the DNA damage response and mitotic progression
FEBS Letters, EarlyView.RAD50 incorporates into the MRN complex and initiates the DNA damage response. Furthermore, RAD50 promotes mitotic progression. RAD50 missense variants capable of forming an MRN complex supported the DNA damage response and mitotic features to different extents in complementation experiments, indicating these functions are separable and might impact ...

Unambiguous Tracking Technique Based on Shape Code for BOC Signals
IEEE Access, 2020 The multiple peaks characteristic of binary offset carrier (BOC) autocorrelation function (ACF) makes ambiguity easy to be generated. There are some methods to eliminate ambiguity, but for higher-order BOC Signal, it will sacrifice signal energy or ...
