The effects of high temperatures on polymer‐derived Nicalon and chemically vapor‐deposited (CVD) SiC fibers have been investigated by mass‐spectrometric vapor pressure studies SEM observations exposed fibers. Vaporization is kinetically limited for both materials; the predominant species vaporizing from SiO, whereas CO predominates in vaporization CVD inherent instability other contact with matrices must be considered ceramic composite fabrication use.
Abstract Traditional custom foot orthoses (CFO) prescription methods often suffer from lengthy processing times, material waste due to re-fabrication, inconsistent performance inaccurate alignment, and inadequate consideration of soft tissue impedance. To address these issues, this study proposes a novel framework for CFO that incorporates adjustable devices, dynamic testing, subject feedback into the design cycle, thereby reducing delivery time. The Arch Height Evaluate Adjust Device...
Prevalence estimates of Parkinson’s disease (PD) – the fastest growing neurodegenerative are underestimated due to issues surrounding diagnostic accuracy, symptomatic undiagnosed cases, suboptimal prodromal monitoring, and limited screening access. Remotely monitored wearable devices sensors provide precise, objective, frequent measures motor non-motor symptoms. Here, we used consumer-grade device sensor data from WATCH-PD study develop a PD tool aimed at eliminating gaps between patient...
Prevalence estimates of Parkinson’s disease (PD)—the fastest-growing neurodegenerative disease—are generally underestimated due to issues surrounding diagnostic accuracy, symptomatic undiagnosed cases, suboptimal prodromal monitoring, and limited screening access. Remotely monitored wearable devices sensors provide precise, objective, frequent measures motor non-motor symptoms. Here, we used consumer-grade device sensor data from the WATCH-PD study develop a PD tool aimed at eliminating gap...
A series of plate impact experiments have been conducted to study the spall strength three principal crystallographic orientations single crystal aluminium ([100], [110] and, [111]) and ultra-pure polycrystalline aluminium. The samples shock loaded at two stresses (4 GPa 10 GPa). Significant differences observed in elastic behaviour, pullback velocities, general shape wave profiles, which can be accounted for by considerations microscale homogeneity, dislocation density, absence grain...
Abstract Compliant mechanisms are typically designed for varying stiffness from nearly zero to rigid. However, targeted design fine-tuning within an application's sensitive range of remains more desirable practical implementation in accurate loading or positioning systems. To achieve various competing objectives, a “generalized spiral spring” (GSS) is proposed which achieves small size and other objectives by using reduced number parameters as provided the shape description components. An...
Abstract In this study, we present a structural optimization framework to design constant force mechanisms (CFMs) with high energy storage capacity. the framework, behavior zero preload is defined be ideal, as has maximum given and displacement limits. A graph-based topology selection, followed by shape conducted select designs most similar of ideal relation. The obtained CFM through higher similarity index compared typical from literature (0.95 versus 0.90). developed study can further...
Abstract Semi-active adjustable constant force mechanisms (ACFMs) are an emerging alternative in applications where energy-efficient control of environments is required. However, there a lack design strategies the literature for semi-active ACFMs. This study addresses this gap by presenting strategy ACFMs that semi-actively tunes structural control. A framework presented, which consists optimization high slenderness large stroke mechanism (CFM) followed parametric on adjusting through...
A passive tuned mass damper can only be designed to have a good damping effect near the resonance frequency of primary structure. To overcome this limitation, novel semi-active with continuously tunable stiffness is proposed in paper. The design features compact mechanism that vary its by changing number active coils parallel and series configurations helical springs. real-time control achieved designing implementing driving system for mechanism. motion characteristics required torque...
Lattice defect structures within large grains of cast polycrystalline silicon have been investigated using optical microscopy, x-ray topography, and electron-beam-induced conductivity (EBIC) measurements. Optical observations through a series wafers an ingot indicate that kinks in high-angle grain boundaries develop by forming straight rather than curved boundaries. It is also observed junction three forms kink the boundary. X-ray topographic lattice defects show cumulative dislocations are...
