Study on Optimization of Delay Method of Wedge Cut Blasting in Tunnel
Shock and Vibration, 2021 Relying on the entrance section of a high-speed railway tunnel blasting project, the fluid-solid coupling algorithm based on ANSYS/LS-DYNA was used to optimize the parameters of wedge cut blasting, and the vibration could be reduced on the basis of ...

Aperiodic order and spherical diffraction, II: Translation bounded measures on homogeneous spaces [PDF]
, 2020 We study the auto-correlation measures of invariant random point processes in the hyperbolic plane which arise from various classes of aperiodic Delone sets. More generally, we study auto-correlation measures for large classes of Delone sets in (and even

Twisted Graphene Bilayers and Quasicrystals: A Cut and Projection Approach [PDF]
Crystals, 2019 In this work, a modified version of the cut and projection approach is proposed to describe the structure of graphene bilayers with twist angles. With this method, the rotation between two graphene layers is viewed as a rotation of the projection space and the resulting projected structure is interpreted as the set of points of best fit between the two

Stripes on rectangular tilings [PDF]
, 2010 We consider a class of cut-and-project sets $\Lambda = \Lambda_F \times \zahl$ in the plane. Let $L=\Lambda+w\real$, $w\in\real^2$, be a countable union of parallel lines.

Constructing bounded remainder sets and cut-and-project sets which are bounded distance to lattices [PDF]
, 2016 For any irrational cut-and-project setup, we demonstrate a natural infinite family of windows which gives rise to separated nets that are each bounded distance to a lattice. Our proof provides a new construction, using a sufficient condition of Rauzy, of

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Constructing bounded remainder sets and cut-and-project sets which are bounded distance to lattices, II [PDF]
, 2016 Recent results of several authors have led to constructions of parallelotopes which are bounded remainder sets for totally irrational toral rotations. In this brief note we explain, in retrospect, how some of these results can easily be obtained from a ...

Construction of Crystallographic Tilings by the Cut-and-Project Method [PDF]
, 2021 Patterns of point sets and tilings were produced and studied for centuries in many cultures. At the border line of mathematics, crystallography, chemistry and physics the general opinion is that every construction for point sets has a counterpart for tilings, but usually this belief is not supported by theorems.
