Rotor Failure Compensation in a Biplane Quadrotor Based on Virtual Deflection

open access: yesDrones, 2022
A biplane quadrotor is a hybrid type of UAV that has wide applications such as payload pickup and delivery, surveillance, etc. This simulation study mainly focuses on handling the total rotor failure, and for that, we propose a control architecture that ...

An Automated Three-Dimensional Bone Pose Tracking Method Using Clinical Interleaved Biplane Fluoroscopy Systems: Application to the Knee

open access: yesApplied Sciences, 2020
Model-based tracking of the movement of the tibiofemoral joint via a biplane X-ray imaging system has been commonly used to reproduce its accurate, three-dimensional kinematics.

Using the 11-point biplane and L 2 ( 11 ) to understand J 1

open access: yes, 2022
In this paper, we use the 11-point biplane and its automorphisms in L2(11) to label and study the Livingstone graph (0) and J1, with an aim of using the simplest methods possible.

Reliability of left atrial strain reference values: A 3D echocardiographic study.

open access: yesPLoS ONE, 2021
BackgroundStandard apical four-chamber and two-chamber views often maximize the long-axis of the left ventricle, resulting in artifactitious foreshortening of the left atrium (LA), which may overestimate LA longitudinal reservoir strain (LALS).

Characterization and Optimization of the Biplane Distance in Three-Dimensional Single-Molecule Localization Microscopy

open access: yesPhotonics
Biplane single-molecule localization microscopy (SMLM) enables three-dimensional (3D) super-resolution imaging by extracting the axial position of fluorophores from a pair of emission patterns detected at two axially separated planes.

The four biplanes with k = 9

open access: yesJournal of Combinatorial Theory, Series A, 1978
AbstractAn exhaustive computer search has established the existence of precisely four biplanes with k = 9. One of the self-dual biplanes is new and a description is provided in terms of its automorphism group. The λ-chain structures for all four biplanes are tabulated.

Effect of Wing-Wing Interaction on the Propulsive Performance of Two Flapping Wings at Biplane Configuration

open access: yesApplied Bionics and Biomechanics, 2018
The biplane counter-flapping wing is a special type of wing flapping which is inspired from the fish and insect in nature. The propulsive performance is one of the most important considerations for this kind of flapping wing.
