Urban spatial form analysis based on the architectural layout -- Taking Zhengzhou City as an example
PLoS ONE, 2022 The analysis of urban spatial form is the basic research of urban development. Traditional fractal research often focuses on the urban spatial layout, which cannot visually express the specific form, change characteristics and development trend of urban ...

Coalgebraic Representation Theory of Fractals
Electronic Notes in Theoretical Computer Science, 2010 AbstractWe develop a representation theory in which a point of a fractal specified by metric means (by a variant of an iterated function system, (IFS) is represented by a suitable equivalence class of infinite streams of symbols. The framework is categorical: symbolic representatives carry a final coalgebra; an IFS-like metric specification of a ...

Slope Deformation Prediction Based on IVDF-SVR Coupling Model
Renmin Zhujiang, 2022 Given the shortcomings of improved variable-dimension fractal in the fitting and prediction of fractal dimensions,this paper proposes a fractal prediction model based on the coupling of the improved variable-dimension fractal (IVDF) theory and the ...

Interval estimation for contact stiffness of bolted joint with uncertain parameters
Advances in Mechanical Engineering, 2019 Bolted joints are elements used to create resistant assemblies in the mechanical system, whose overall performance is greatly affected by joints’ contact stiffness. Most of the researches on contact stiffness are based on certainty theory whereas in real
