Dynamic modeling and characteristics study of airdrop folding multi-body aircraft

Xibei Gongye Daxue Xuebao
In the processes of launch, development and fall at high altitude without initial velocity, the dynamics model of a folding multi-body aircraft shows the characteristics of a multi-rigid body and multi-degree of freedom. The relative motion of each rigid

Acoustic manipulation of multi-body structures and dynamics

Reports on Progress in Physics
Abstract Sound can exert forces on objects of any material and shape. This has made the contactless manipulation of objects by intense ultrasound a fascinating area of research with wide-ranging applications. While much is understood for acoustic forcing of individual objects, sound-mediated interactions among multiple objects at close ...

Inverse and forward dynamics: models of multi–body systems [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
Connected multi–body systems exhibit notoriously complex behaviour when driven by external and internal forces and torques. The problem of reconstructing the internal forces and/or torques from the movements and known external forces is called the ‘inverse dynamics problem’, whereas calculating motion from known internal forces and/or torques and ...

Method for Analysis of an Offshore Heave Compensator

Applied Sciences, 2016
A heave compensation system consists of a drill string compensator (DSC) and an active heave compensator (AHC) cylinder, which together produce control force over an oil pressure system suitable for transmission of considerable power and compensating for

Different Scenarios for Critical Glassy Dynamics

, 2000
We study the role of different terms in the $N$-body potential of glass forming systems on the critical dynamics near the glass transition. Using a simplified spin model with quenched disorder, where the different terms of the real $N$-body potential are

Multi-body Dynamics Study of Gears [PDF]

, 2022
Gear faults can usually occur due to fatigue, spalling or pitting caused by wear, load fluctuations, backlash etc. This severely reduces actual strength of the gears and prompts crack growth. Fatigue cracks may appear in the region of highest stresses, whose location can be determined based on numerical analysis, meshing force variability, point of ...

Time Toxicity in Wilms Tumor: Quantifying the Burden of Healthcare Interaction in the First Year After Diagnosis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

Non-equilibrium dynamics of an ultracold Bose gas under a multi-pulsed quantum quench in interaction

, 2015
We investigate the nonequilibrium dynamical properties of a weakly-interacting Bose gas at zero temperature under the multi-pulsed quantum quench in interaction by calculating one-body, two-body correlation functions and Tan's contact of the model system.

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...
