Critical percolation in finite geometries [PDF]

open access: yesJournal of Physics A: Mathematical and General, 1992
The methods of conformal field theory are used to compute the crossing probabilities between segments of the boundary of a compact two-dimensional region at the percolation threshold. These probabilities are shown to be invariant not only under changes of scale, but also under mappings of the region which are conformal in the interior and continuous on

Integration of numerical analysis, virtual simulation and finite element analysis for the optimum design of worm gearing [PDF]

open access: yes, 2003
Due to the complicated tooth geometry of worm gears, their design to achieve high capacity and favourable performance is a tedious task, and the optimum design is hardly to obtain.

Loads in the design of flight vehicles [PDF]

open access: yesINCAS Bulletin, 2010
The calculation of flight loads is a critical part of air vehicle design. On the other hand, the prediction of accurate loads is a sophisticated and complex process that requires skilled and experienced engineers.

Poisson algebras via model theory and differential-algebraic geometry [PDF]

open access: yes, 2017
Brown and Gordon asked whether the Poisson Dixmier–Moeglin equivalence holds for any complex affine Poisson algebra, that is, whether the sets of Poisson rational ideals, Poisson primitive ideals, and Poisson locally closed ideals coincide.

Some problems in extremal graph theory and finite geometry

open access: yes, 2023
Lazebnik, FelixThis thesis is devoted to the study of several problems in extremal graph theory and finite geometry. We study properties such as girth, spectrum, and automorphism group of various families of algebraically defined graphs. We present a new

More on complexity in finite cut off geometry

open access: yesPhysics Letters B, 2019
It has been recently proposed that late time behavior of holographic complexity in a uncharged black brane solution of Einstein-Hilbert theory with boundary cut off is consistent with Lloyd's bound if we have a cut off behind the horizon.

On finite moore geometries

open access: yesJournal of Combinatorial Theory, Series A, 1977
AbstractConditions are given which must be satisfied by the parameters of a Moore geometry. It is shown that there are no nontrivial Moore geometries of diameter 3.

Geometry Optimization of Sheet Specimen for the Measurement Accuracy Improvement in the Hopkinson Bar Based on Intelligent Algorithm

open access: yesIEEE Access, 2020
At present, the split Hopkinson tensile bar (SHTB) is widely used to determine the dynamic tensile properties of materials under high strain rates, in which sheet specimen with dogbone-shaped structure is commonly adopted.

Towards the isogeometric aero-engine

open access: yesResults in Engineering, 2023
Creating very detailed finite element models of aero-engines is a very time-consuming process especially if structured meshes have to be generated for thousands of parts.
