A novel detection of radio-frequency signal based on an electro-opto-mechanical converter
Results in Physics, 2022 We study a novel detection of radio frequency signal, which is realized by the coherent microwave-optical conversion and optical processing. An electro-opto-mechanical converter, which enables the bidirectional transduction of the information between ...

Neural Topological SLAM for Visual Navigation [PDF]
Computer Vision and Pattern Recognition, 2020 This paper studies the problem of image-goal navigation which involves navigating to the location indicated by a goal image in a novel previously unseen environment. To tackle this problem, we design topological representations for space that effectively

Hippocampus and retrosplenial cortex combine path integration signals for successful navigation [PDF]
, 2013 The current study used fMRI in humans to examine goal-directed navigation in an open field environment. We designed a task that required participants to encode survey-level spatial information and subsequently navigate to a goal location in either first ...

Learning navigation – Learning with navigation. A review [PDF]
SICOT-J, 2017 The goal of this review paper is to retrieve from the existing literature relevant information (1) about the learning curve of the currently existing navigation systems and (2) about the use of navigation system for teaching orthopaedic procedures. All studies reporting on the learning curve of navigation systems support the hypothesis that computer ...

Quantum Navigation and Ranking in Complex Networks [PDF]
, 2012 Complex networks are formal frameworks capturing the interdependencies between the elements of large systems and databases. This formalism allows to use network navigation methods to rank the importance that each constituent has on the global ...

BOC Signal Acquisition Algorithm Based on Similar Enfoldment
International Journal of Aerospace Engineering, 2020 A BOC signal has been widely used in the Global Navigation Satellite System (GNSS). Although the BOC signal has many advantages, the autocorrelation function (ACF) of the BOC signal has lots of peaks, which makes signal acquisition difficult.

Langenbeck's Archives of Surgery, 2013 "Navigation in surgery" spans a broad area, which, depending on the clinical challenge, can have different meanings. Over the past decade, navigation in surgery has evolved beyond imaging modalities and bulky systems into the rich networking of the cloud or devices that are pocket-sized.This article will review various aspects of navigation in the ...

Target-driven visual navigation in indoor scenes using deep reinforcement learning [PDF]
IEEE International Conference on Robotics and Automation, 2016 Two less addressed issues of deep reinforcement learning are (1) lack of generalization capability to new goals, and (2) data inefficiency, i.e., the model requires several (and often costly) episodes of trial and error to converge, which makes it ...

Vision-Only Robot Navigation in a Neural Radiance World [PDF]
IEEE Robotics and Automation Letters, 2021 Neural Radiance Fields (NeRFs) have recently emerged as a powerful paradigm for the representation of natural, complex 3D scenes. NeRFs represent continuous volumetric density and RGB values in a neural network, and generate photo-realistic images from ...

Investigation of the use of navigation tools in web-based learning: A data mining approach [PDF]
, 2008 Web-based learning is widespread in educational settings. The popularity of Web-based learning is in great measure because of its flexibility. Multiple navigation tools provided some of this flexibility.
