Seismic energy dissipation capacity of confined concrete columns with infilled-AAC bricks subjected to quasi-static cyclic loading by Bambang Sabariman, Tavio, Slamet Widodo

“…The results indicate that its capability to dissipate the earthquake energy still satisfies all three criteria of the ACI 374.1-05 provisions, such as capability to carry loads > 0.75Ph-max, relative energy dissipation ratio (β) > 0.125, and gradient hysteresis loop limited by drift ratio limit (-0.35% and +0.35) > 0.05. …”

The Effect of Fine-Grained Control of Workflow on Informal Learning: The Mediating Effect of Teacher Burnout by Zenghui Lu, Yanning Chen

“…The model designs a measurement scale based on the results of fine control, and the scale is revised through informal learning pretests to form the logical frame analysis loop of this paper. The scale uses Likert 5-point scoring, from 1.5 to represent never, rarely, occasionally, often, and always, which solves the difficulty of quantitative analysis of teacher burnout data. …”

Fuzzy Adaptive Prescribed Performance Fault-Tolerant Control for HFVs with Fixed-Time Convergence Guarantee by Zehong Dong, Yinghui Li, Maolong Lv, Zilong Zhao, Binbin Pei

“…Fuzzy logic systems (FLSs) are employed to handle unknown dynamics, and minimal learning parameter (MLP) technique is incorporated into the design for the purpose of alleviating computation burden. Closed-loop stability is rigorously proved via Lyapunov stability theory, and simulation results are eventually given to validate the effectiveness of the proposed control strategy.…”

Enhanced Dynamic Model of Pneumatic Muscle Actuator with Elman Neural Network by Alexander Hošovský, Ján Piteľ, Kamil Židek

“…Use of analytical model makes it possible to retain the physical interpretation of the model and the model is validated using open-loop responses. Since it was considered important to design a robust controller based on this model, the effect of changed moment of inertia (as a representation of uncertain parameter) was taken into account and compared with nominal case. …”
