Agent‐Based Computational Modeling of the Stochastic Dynamic Behavior of Actin Filaments Recapitulates the Homeostatic Cortical Array in Plant Epidermal Cells

Cytoskeleton, EarlyView.
ABSTRACT The homeostatic cortical actin array in plant cells plays important roles in fundamental processes, including intracellular transport, secretion, cell expansion, and cytoplasmic streaming. In response to diverse chemical and mechanical signals, the cortical array can remodel within minutes to assume new configurations or altered filament ...

Quantifying Parametric Influence on Cuttings Transport in Deviated Deep Wells Using Global Sensitivity Analysis Methods

Energy Science &Engineering, EarlyView.
Cuttings transport simulation workflow. ABSTRACT Efficient cuttings transport is essential for wellbore stability and minimizing non‐productive time in deviated and horizontal wells. This study applies global sensitivity analysis (GSA) to evaluate the influence of 14 drilling parameters on cuttings transport using WellPlanTM hydraulic simulations ...

Design of HAWT Rotor for Non‐Uniform Inflow Conditions: A Theoretical and Experimental Approach for Shear Flow

Energy Science &Engineering, EarlyView.
This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...

Systematic Parameter Selection for Short Fiber Polymer Composite Direct Fiber Simulation

Polymer Composites, EarlyView.
Interactions of individually simulated fibers are systematically calibrated such that their orientation history agrees with the results from analytical orientation models. ABSTRACT The orientation of fibers in short discontinuous fiber reinforced polymer composites is a critical factor in determining final mechanical and thermal properties.

In‐situ Analysis of Paste Properties in Resonant Acoustic Mixers for Quality Monitoring

Propellants, Explosives, Pyrotechnics, EarlyView.
Quality monitoring is important to ensure manufacturing robustness and achieve consistent properties. For the emerging technology resonant acoustic mixing, this work uses motor data to detect differences in particle content in formulations and variations in powder feedstock properties.

Dynamic Event‐Triggered Robust Model Predictive Control for Quadrotor Trajectory Tracking

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper addresses the trajectory tracking problem for a full‐state quadrotor subject to physical model constraints and unknown external disturbances. A robust tube‐based model predictive control (MPC) approach is successfully applied to the system, which is subject to bounded disturbances and hard constraints.

SensHB.Q: A Cost‐Effective Force‐Sensitive Handlebar to Control Omnidirectional Robots and Wheelchairs

Journal of Field Robotics, EarlyView.
ABSTRACT This paper details the design and development of SensHB.Q, a force‐sensitive handlebar intended for caregivers driving electric‐powered wheelchairs, particularly those with omnidirectional mobility. The same interface can also be used in the future to operate other omnidirectional motorized systems, such as mobile robots, hospital beds, and ...

Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

Journal of Field Robotics, EarlyView.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.
