Resilient city has attracted global attentions as a new concept for cities to deal with risks and challenges in recent years. Numerous researchers have successively conducted in-depth studies on the resilient from different perspectives. To acquire an overview of grasp current research hotspots, bibliometric analysis visualization past decade was made. The data were collected 1249 articles published Web Science database 2010 2019. As widely used tools, CiteSpace VOSviewer adopted this study....
Response characteristics of key strata during the periodic weighting process in Dongjiahe coal mine were investigated using micro-seismic (MS) monitoring. Fracture types identified through moment tensor inversion. Finally, fracture mechanism roof was revealed from a microscopic viewpoint. The results show that there are three concentrations MS events distributed along dip direction. And two event clusters formed "pairs" before and behind working face. Along strike direction, tensile shear...
In this paper, a high-sensitivity microelectromechanical system (MEMS) piezoelectric accelerometer based on Scandium-doped Aluminum Nitride (ScAlN) thin film is proposed. The primary structure of silicon proof mass fixed by four cantilever beams. order to enhance the sensitivity accelerometer, Sc0.2Al0.8N used in device. transverse coefficient d31 measured beam method and found be −4.7661 pC/N, which approximately two three times greater than that pure AlN film. To further top electrodes are...
Gas sensor-embedded smartphones would offer the opportunity of on-site tracking gas molecules for various applications, example, harmful air pollutant alarms or noninvasive assessment health status. Nevertheless, high power consumption and difficulty in replacing malfunctioned sensors as well limited space smartphone to host sensor restrain relevant advancements. In this article, we create a case-based sensing platform by integrating functional units into case, which performs low detection...
Determination of joint stiffness, one the most important mechanical properties rock joints, is great significance. However, stiffness often difficult to complete and accurate determine because 3D nature joints limited budgets visible exposure. Wave attenuation in a mass mainly attributed presence joints. Based on 1D plane-wave theory, rapid nondestructive method, namely, evaluation proposed calculate normal shear The viewed as boundary condition modeled by displacement discontinuity model....
Rock joints are one of the vital discontinuities in a natural rock mass. How to accurately and conveniently determine joint normal stiffness is therefore significant mechanics. Here, first, seven existing methods for determining were introduced reviewed, among which Method I (the indirect measurement method), II direct determination III across-joint strain gauge method) IV deformation measuring ring via destructive uniaxial compression testing, while V best fitting VI rapid evaluation VII...
The abrupt rock-related hazards, such as landslide, rock burst, and collapse, seriously threaten the safety service life of engineering works. Precursory information on critical transitions preceding sudden fracture is great significance in mechanics engineering. This study investigates slowing down feature acoustic emission (AE) signals precursory indicators during mode I process brittle rock. Cracked chevron notched Brazilian disc (CCNBD) specimens were utilized, accompanied by monitoring....
The paper proposes a new multiple-factor clustering method (NMFCM) with consideration of both box fractal dimension (BFD) and orientation joints. This assumes that the BFDs different clusters were uneven, was performed by redistributing joints near boundaries on polar map to maximize an index for estimating difference BFD (DBFD). Three main aspects studied develop NMFCM. First, procedures NMFCM reasonableness assumptions illustrated. Second, factors affecting investigated numerical...
