Design of Experiments‐Based Optimization of Recovered Carbon Black–Reinforced Isobutylene–Isoprene Rubber in Comparison With Conventional Carbon Black Systems

open access: yesJournal of Applied Polymer Science, EarlyView.
Optimized potential of rCB via DOE: recovered carbon black from end‐of‐life tires was assessed as a full substitute for conventional carbon black in IIR composites. DOE and response surface methodology optimized rCB loading, plasticizer, and sulfur contents. Hardness showed linear trends, while rupture energy was nonlinear.

Effectiveness of an inlet flow turbulence control device to simulate flight noise fan in an anechoic chamber [PDF]

open access: yes
A hemispherical inlet flow control device was tested on a 50.8 cm. (20-inch) diameter fan stage in the NASA-Lewis anechoic chamber. The control device used honeycomb and wire mesh to reduce turbulence intensities entering the fan.

Adaptive mixing formation control of multiquadrotor unmanned aerial vehicle systems

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper presents a distributed adaptive mixing control (AMC) design for formation maintenance of systems of multiquadrotor UAVs (q‐UAVs) during commanded path‐tracking maneuvers. The proposed formation control scheme has a two‐level structure. The high level defines the desired trajectories for rigid and persistent formation acquisition and

A compatibility criterion for optimal control and information aggregation in hierarchical network systems

open access: yesAsian Journal of Control, EarlyView.
Abstract Large swarms often adopt a hierarchical network structure that incorporates information aggregation. Although this approach offers significant advantages in terms of communication efficiency and computational complexity, it can also lead to degradation due to information constraints.

Single stage, low noise advanced technology fan. Volume 3: Acoustic design [PDF]

open access: yes
The acoustic design for a half-scale fan vehicle, which would have application on an advanced transport aircraft, is described. The single stage advanced technology fan was designed to a pressure ratio of 1.8 at a tip speed of 503 m/sec (1,650 ft/sec ...

Genetic code expansion for chemosensing and chemical actuation of biological functions

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Genetic code expansion (GCE) broadens the chemical repertoire for precise control of protein function in biological systems. This review highlights GCE‐based sensing and actuating systems that operate through selective interactions between noncanonical amino acids and chemical triggers.

Supramolecular Host‐Guest Complexation Dynamics by Cost‐Efficient Electronic Structure Methods

open access: yesChemistry – A European Journal, EarlyView.
We present a cost‐effective multilevel workflow for the kinetic profiling of host–guest systems, illustrated with cucurbit[6]uril and alkylammonium cations. The method combines rapid docking and reaction path searches at the semi‐empirical level, with refinement of the results using modern density functional theory, accurately reproducing experiment ...
