Adaptive mixing formation control of multiquadrotor unmanned aerial vehicle systems
Asian 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

Asian 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.

Effective pretreatment of wet microalgal biomass to enhance lipid extraction in biodiesel production
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Biodiesel is a viable alternative to fossil fuels. Identifying and evaluating nonedible sources is essential to address ecological concerns and meet energy demands. Microalgae are effective for lipid production but their rigid cell walls hinder bioproduct release making the process energy‐intensive and costly.

A comparison of theory and experiment for coupled rotor body stability of a bearingless rotor model in hover and forward flight [PDF]
Seven cases were selected for correlation from a 1/5.86 Froude-scale experiment that examined several rotor designs which were being considered for full-scale flight testing as part of the Bearingless Main Rotor (BMR) program. The model rotor hub used in

Force stimulation promotes nerve regeneration by restoring cellular energy
BMEMat, EarlyView.Mechanical stimulation can help nerves regenerate in various ways. We developed two devices (a piezo‐motor‐driven stretching device and a SAW‐based actuator) to apply mechanical stimulation to sciatic nerve and DRG neurons. Our study shows that appropriate mechanical force stimulation can promote regeneration by restoring the energy supply to the ...

Clinical Advances in Periodontics, EarlyView.Abstract Background In soft tissue regeneration, the clinical efficacy of fibrin membranes has been a pressing concern. The key to this efficacy lies in the stability of membrane and its controlled absorption. Human serum albumin, with its influence on the formation and stability of fibrin networks, could hold the key to developing a more stable ...
