THE GEOMETRY OF COASTLINES: A STUDY IN FRACTALS
Computers & Mathematics with Applications, 1986 AbstractThe geometry of coastlines, based on an empirical study by Lewis Richardson, is presented as a way of introducing the subject of fractals developed by Benoit Mandelbrot. It is shown how the statistically self-similar nature of coastlines can be generalized to an interesting class of point sets, curves and surfaces with the same property ...

Energy Science &Engineering, EarlyView.论文陈述 Paper Statement 本研究揭示了不同宏观煤岩类型的差异化控气机制:半亮煤是主要“储气核心,” 光亮煤为关键“渗流通道,” 暗淡煤则是“初期高产贡献者”。这为深层煤层气甜点优选与定制开发提供了关键理论依据。 This study reveals the differentiated gas‐controlling mechanisms of different macroscopic coal lithotypes: semibright coal acts as the primary “gas storage core,” bright coal serves as the critical “seepage channel,” and dull coal functions

Energy Science &Engineering, EarlyView.A stress wave propagation model for coal‐rock combinations under in situ stress was established. Taking a coal mine in Huainan, China as the engineering background, isotropic and anisotropic numerical models were constructed. Field engineering practices were carried out to verify the reliability of the conclusions.

Fractal Geometry on Hyperbolic Manifolds
, 2006 In this survey we give a report on some recent results obtained in the studies of hyperbolic manifolds by means of fractal geometry. Emphasis has been put on results derived in the quantitative and qualitative fractal analysis of long term geodesic dynamics on hyperbolic manifolds.

Mechanical stability in flexible perovskite solar cells: Interface engineering and device design
FlexMat, EarlyView.Statistics of the improvement methods for f‐PSCs. Abstract Flexible perovskite solar cells (f‐PSCs) demonstrate significant potential for application in next‐generation wearable electronic devices and photovoltaic building integration due to their high power conversion efficiency and excellent power‐to‐weight ratio. However, the inherent brittleness of
