Application of the Motion Capture System to Estimate the Accuracy of a Wheeled Mobile Robot Localization

open access: yesEnergies, 2020
The paper presents research on methods of a wheeled mobile robot localization using an optical motion capture system. The results of localization based on the model of forward kinematics and odometric measurements were compared. A pure pursuit controller

Deep learning assisted high‐resolution microscopy image processing for phase segmentation in functional composite materials

open access: yesJournal of Microscopy, EarlyView.
Abstract In the domain of battery research, the processing of high‐resolution microscopy images is a challenging task, as it involves dealing with complex images and requires a prior understanding of the components involved. The utilisation of deep learning methodologies for image analysis has attracted considerable interest in recent years, with ...

Development and Validation of an AI‐Integrated System for Automated Fracture Detection and Pedicle Puncture Planning in Lumbar Osteoporotic Vertebral Compression Fractures Based on the Nine‐Grid Area Division Method

open access: yesOrthopaedic Surgery, EarlyView.
This study developed a three‐module AI‐integrated software. Its effectiveness was verified, and it was confirmed to have certain transformation potential. ABSTRACT Objective The clinical application of the Nine‐grid Area Division Method for pedicle puncture in L‐OVCF is limited by high technical thresholds and low efficiency.

On non-separable components of hyperspaces with the Hausdorff metric [PDF]

open access: yesМатематичні Студії, 2011
Let $(X,d)$ be a connected non compact metric space. Suppose the metric$d$ convex and such that every closed bounded subset of $X$ is compact. Let $F(X)$ bethe space of nonvoid closed subsets of $X$ with the Hausdorff distance associated to $d$.We prove ...

Phenological Observations on Classical Prehistoric Sites in the Middle and Lower Reaches of the Yellow River Based on Landsat NDVI Time Series

open access: yesRemote Sensing, 2017
Buried archeological features show up as crop marks that are mostly visible using high-resolution image data. Such data are costly and restricted to small regions and time domains.

Recovering metric from full ordinal information

open access: yes, 2018
Given a geodesic space (E, d), we show that full ordinal knowledge on the metric d-i.e. knowledge of the function D d : (w, x, y, z) $\rightarrow$ 1 d(w,x)$\le$d(y,z) , determines uniquely-up to a constant factor-the metric d.

Lectures on Hausdorff and Gromov-Hausdorff Distance Geometry

open access: yes, 2020
The course was given at Peking University, Fall 2019. We discuss the following subjects: (1) Introduction to general topology, hyperspaces, metric and pseudometric spaces, graph theory. (2) Graphs in metric spaces, minimum spanning tree, Steiner minimal tree, Gromov minimal filling.

Structural determinants of re‐entrant drivers in atrial fibrillation: insights from digital twins derived from 3D micrometre‐resolution imaging of human heart

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Digital heart models of human donor atria with cardiac co‐morbidities revealed that regions with AWT variation, aligned myofibres adjacent to disorganised zones and fibrotic borders promoted the localisation and stability of RDs. AWT had a global influence, whereas fibre orientation and fibrosis exerted chamber‐specific regional ...

Some Properties and Applications of the Hausdorff Distance

open access: yesJournal of Optimization Theory and Applications, 2015
Some properties of Hausdorff distance are studied. It is shown that, in every infinite-dimensional normed space, there exists a pair of closed and bounded sets such that the distance between every two points of these sets is greater than the Hausdorff distance between these sets.
