Predicting Long-Range Traversability from Short-Range Stereo-Derived Geometry [PDF]

Based only on its appearance in imagery, this program uses close-range 3D terrain analysis to produce training data sufficient to estimate the traversability of terrain beyond 3D sensing range. This approach is called learning from stereo (LFS).

New X-ray observations of the Geminga pulsar wind nebula

, 2010
Previous observations of the middle-aged pulsar Geminga with XMM-Newton and Chandra have shown an unusual pulsar wind nebula (PWN), with a 20" long central (axial) tail directed opposite to the pulsar's proper motion and two 2' long, bent lateral (outer)

DeepDriving: Learning Affordance for Direct Perception in Autonomous Driving

, 2015
Today, there are two major paradigms for vision-based autonomous driving systems: mediated perception approaches that parse an entire scene to make a driving decision, and behavior reflex approaches that directly map an input image to a driving action by

An Integrated Path Planning and Tracking Framework Based on Adaptive Heuristic JPS and B-Spline Optimization

Machines
In this paper, we propose a navigation synthesis method for indoor mobile robots based on the Improved Jumping Point Search (JPS) framework. Although traditional JPS has high search efficiency, it often leads to excessive node expansion and sharp turns ...

Development of an Adaptive Fuzzy Integral-Derivative Line-of-Sight Method for Bathymetric LiDAR Onboard Unmanned Surface Vessel

Remote Sensing
Previous control methods developed by our research team cannot satisfy the high accuracy requirements of unmanned surface vessel (USV) path-tracking during bathymetric mapping because of the excessive overshoot and slow convergence speed. For this reason,

A Corrector-aided Look-ahead Distance-based Guidance for Online Reference Path Following with an Efficient Mid-course Guidance Strategy

Efficient path-following is crucial in most of the applications of autonomous vehicles (UxV). Among various guidance strategies presented in literature, the look-ahead distance ($L_1$)-based nonlinear guidance has received significant attention due to its ease in implementation and ability to maintain a low cross-track error while following simpler ...

INTERROGATING EPISTEMIC FOUNDATIONS [PDF]

Annals of the University of Craiova for Journalism, Communication and Management
Offering convenient and adaptable learning opportunities on a global scale, open distance e-learning (ODeL) has become a game-changer in the field of higher education. But we must look closely at its epistemic underpinnings. Through a critical lens, this
