This work introduces a novel concept of modular, shape-adaptable sandwich panel with distributed actuation system based on shape memory alloys (SMA). The consists modular arrangement rigid cells connected compliant active joints. Each joint hosts SMA wire, which can be controlled independently, enabling the to achieve multiple shapes and complex curvatures single design. A numerical model actua...

In recent years, aluminum alloy has been increasingly used in building structures, becoming an important construction material for metal structures. Currently, is commonly buildings as beam–column components, profiled roof panels, and door window frames, among other forms. However, there limited research on the mechanical properties of panels with irregular curved surfaces. this study, a full-s...

Low-frequency sound transmission through passive lightweight partitions often renders them ineffective as means of sound isolation. As a result, researchers have investigated actively controlled lightweight partitions in an effort to remedy this problem. One promising approach involves active segmented partitions (ASPs), in which partitions are segmented into several distinctly controlled modul...

Taking a double-line underground excavation subway tunnel underneath the medium-low-speed Maglev bridge section of Beijing S1 Metro line as project reference, deformation control index metro and track panel was studied using numerical simulation data monitoring, under conditions deep-hole grouting measures for soil layer around active lifting superstructure viaduct. The results show that maximu...

We designed a molecular complex, the double-double crossover, consisting of four DNA double helices connected by six reciprocal exchanges. Atomic force micrographs suggest that double-double crossover complexes self-assemble into high-density, doubly connected, two-dimensional, planar structures. Such structures may be suitable as substrates for the deposition of nanomaterials in the creation o...

In the context of panel ordered-response structures, the current paper compares the performance of the maximum-simulated likelihood (MSL) inference approach and the composite marginal likelihood (CML) inference approach. The panel structures considered include the pure random coefficients (RC) model with no autoregressive error component, as well as the more general case of random coefficients ...
