Cracking Patterns of Brittle Hemispherical Domes: an Experimental Study
Fracture and Structural Integrity, 2021 Crack formation in hemispherical domes is a distinguished problem in structural mechanics. The safety of cracked domes has a long track record; the evolution of the cracking pattern received less attention.

Geometric models of Helium [PDF]
Modern Physics Letters A, 2017 A previous paper [M. F. Atiyah and N. S. Manton, arXiv:1609.02816 ] modeled atoms and their isotopes by complex algebraic surfaces with the projective plane modeling Hydrogen. In this paper, models of the stable isotopes Helium-4 and Helium-3 are constructed.

Hypergraph modelling for geometric model fitting [PDF]
Pattern Recognition, 2016 In this paper, we propose a novel hypergraph based method (called HF) to fit and segment multi-structural data. The proposed HF formulates the geometric model fitting problem as a hypergraph partition problem based on a novel hypergraph model. In the hypergraph model, vertices represent data points and hyperedges denote model hypotheses. The hypergraph,

Optimization of voids in concrete ceilings: A geometrical approach [PDF]
FME Transactions, 2019 The task to reduce the material consumption in the building industry is urgent. Conserving concrete saves nature and money. To reduce the consumption of concrete in buildings we design hollow bodies in ceiling structures.
