Deterministic fractals and fractal measures

open access: yes, 1991
This is a survey paper on the general theory of fractals and fractal measures containing several proofs and exercises. It has the style of Lecture Notes and is suitable for a short introduction on this subject. The paper is concentrated on questions which have not been completely worked out in the main reference books of this subject as are \textit{K ...

Shear behavior of bolt–grout interfaces under constant normal stiffness: Influence of grout strength and thickness

open access: yesDeep Underground Science and Engineering, EarlyView.
The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

Of all shapes and sizes: a theoretical framework for animal‐mediated terrestrial heterogeneity across scales

open access: yesEcography, EarlyView.
Animals redistribute elements throughout their lives by depositing wastes and carcasses. Growing evidence shows that these zoogeochemical processes enhance landscape diversity and heterogeneity worldwide. We provide a descriptive framework for understanding how direct animal depositions (i.e.

Image‐Based Quantification of Deposited Lithium on Li Metal Surfaces

open access: yesEnergy Technology, EarlyView.
Images of lithium deposition in a Li||Li in situ cell are recorded. Two evaluation algorithms, a rule‐based approach and a neural network‐based approach, are designed and then used to evaluate the lithium deposition process. These algorithms allow to quickly and objectively assess and quantify the lithium deposition process, determining its physical ...
