Optimization of a Composite Wing Subject to Multi Constraints [PDF]

, 2013
In this thesis, an investigation has been carried out into a minimum weight optimization analysis of a composite wing with multi design constraints under both static and dynamic loadings. The study includes the influence of a morphing leading edge on the

Transdiagnostic profiles of socio‐affective functioning in adolescents at‐risk of poor mental health

JCPP Advances, EarlyView.
Abstract Background Adolescence is a developmental period during which many mental health problems emerge or worsen. Recently, there has been a shift towards identifying risk factors that predict psychopathology across a range of diagnostic boundaries—known as ‘transdiagnostic’ approaches.

Analysis and optimization of a camber morphing wing model

International Journal of Advanced Robotic Systems, 2016
This article proposes a camber morphing wing model that can continuously change its camber. A mathematical model is proposed and a kinematic simulation is performed to verify the wing’s ability to change camber.

MR Imaging‐Based Biomarkers for Strength Prediction: A Statistical Shape and Architecture Modeling of Quadriceps Muscles

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Muscle mass decline, associated with strength decline, is a hallmark of aging. Yet, strength decline greatly exceeds mass decline. This indicates that aspects of muscle quality and architecture—not reflected by mass—also influence force generating capacity.

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Physical Anchoring‐Assisted Mechanically Guided Assembly for Material‐Independent 3D Mesostructures

Small, EarlyView.
Conventional mechanically guided 3D assembly relies on selective chemical bonding between 2D precursors and elastomeric substrates, imposing fundamental limitations on material compatibility and scalability. Here, we present a physically anchored, buckling‐guided assembly platform based on a rod array patterned elastomeric substrate (RPES).
