Dynamic Models Identification for Kinematics and Energy Consumption of Rotary-Wing UAVs during Different Flight States [PDF]

open access: yesSensors, 2023
This article presents the method of identifying dynamic models for different flight states of a rotary-wing UAV for simulations. Experimental flights with real-life UAVs were conducted to obtain data necessary for identification.

Quantifying continental collision dynamics for Alpine-style orogens

open access: yesFrontiers in Earth Science, 2022
When continents collide, the arrival of positively buoyant continental crust slows down subduction. This collision often leads to the detachment of earlier subducted oceanic lithosphere, which changes the subsequent dynamics of the orogenic system ...

A Recurrent Neural-Network-Based Real-Time Dynamic Model for Soft Continuum Manipulators

open access: yesFrontiers in Robotics and AI, 2021
This paper introduces and validates a real-time dynamic predictive model based on a neural network approach for soft continuum manipulators. The presented model provides a real-time prediction framework using neural-network-based strategies and continuum

On the Origins and Rarity of Locally but Not Globally Identifiable Parameters in Biological Modeling

open access: yesIEEE Access, 2023
Structural identifiability determines the possibility of estimating the parameters of a model by observing its output in an ideal experiment. If a parameter is structurally locally identifiable, but not globally (SLING), its true value cannot be uniquely

Foundations and modelling of dynamic networks using Dynamic Graph Neural Networks: A survey [PDF]

open access: yes, 2021
Dynamic networks are used in a wide range of fields, including social network analysis, recommender systems, and epidemiology. Representing complex networks as structures changing over time allow network models to leverage not only structural but also ...

Characterizing the Vibration Responses of Flexible Workpieces during the Turning Process for Quality Control

open access: yesApplied Sciences, 2023
The chatter that occurs during the turning operation, especially when cutting a slender and flexible shaft, determines the surface quality of the workpiece and the stability of the machining system.

Dynamic models in fMRI [PDF]

open access: yes, 1998
Most statistical methods for assessing activated voxels in fMRI experiments are based on correlation or regression analysis. In this context the main assumptions are that the baseline can be described by a few known basis-functions or variables and that

Real-Time Terrain-Following of an Autonomous Quadrotor by Multi-Sensor Fusion and Control

open access: yesApplied Sciences, 2021
For the application of the autonomous guidance of a quadrotor from confined undulant ground, terrain-following is the major issue for flying at a low altitude.
