IVU-AutoNav: Integrated Visual and UWB Framework for Autonomous Navigation

Drones
To address the inherent scale ambiguity and positioning drift in monocular visual Simultaneous Localization and Mapping (SLAM), this paper proposes a novel localization method that integrates monocular visual SLAM with Ultra-Wideband (UWB) ranging ...

Temperature‐Dependent Kinetics of Plasma‐Based CO2 Conversion: Interplay of Electron‐Driven and Thermal‐Driven Chemistry

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.

VIGS-SLAM: Visual Inertial Gaussian Splatting SLAM

We present VIGS-SLAM, a visual-inertial 3D Gaussian Splatting SLAM system that achieves robust real-time tracking and high-fidelity reconstruction. Although recent 3DGS-based SLAM methods achieve dense and photorealistic mapping, their purely visual design degrades under motion blur, low texture, and exposure variations.

Upsetting experiences in the lives of neurodivergent young people: A qualitative analysis of accounts of adolescents diagnosed with attention‐deficit/hyperactivity disorder and/or autism

JCPP Advances, EarlyView.
Abstract Background Accounts of emotional dysregulation in autism and attention‐deficit/hyperactivity disorder (ADHD) are typically based on external adult observations anchored in neurotypical notions of emotional responding. These often fail to place neurodivergent people's emotional responses in the context of the upsetting experiences they face ...

Improved Visual SLAM Algorithm Based on Dynamic Scenes

Applied Sciences
This work presents a novel RGB-D dynamic simultaneous localization and mapping (SLAM) method that improves accuracy, stability, and efficiency of localization while relying on deep learning in a dynamic environment, in contrast to traditional static ...

Pixel-Wise Motion Segmentation for SLAM in Dynamic Environments

IEEE Access, 2020
Visual simultaneous localization and mapping (SLAM) is a key prerequisite for many mobile robotic systems. A common assumption for SLAM methods is a static environment.

Learning Meshes for Dense Visual SLAM

2019 IEEE/CVF International Conference on Computer Vision (ICCV), 2019
Estimating motion and surrounding geometry of a moving camera remains a challenging inference problem. From an information theoretic point of view, estimates should get better as more information is included, such as is done in dense SLAM, but this is strongly dependent on the validity of the underlying models.

Tactile hypo‐responsivity in autism: Examining potential for diagnostic relevance

JCPP Advances, EarlyView.
The study reported in this paper examined the utility of a brief tactile reactivity assessment in differentiating autistic children from those with other neurodevelopmental concerns and the association between tactile responsivity, autism symptomatology, developmental level, and adaptive skills.

Navigation without localisation: reliable teach and repeat based on the convergence theorem

, 2018
We present a novel concept for teach-and-repeat visual navigation. The proposed concept is based on a mathematical model, which indicates that in teach-and-repeat navigation scenarios, mobile robots do not need to perform explicit localisation.
