The pentagon relation and incidence geometry [PDF]
Journal of Mathematical Physics, 2011 We define a map S: D^2 x D^2 --> D^2 x D^2, where D is an arbitrary division ring (skew field), associated with the Veblen configuration, and we show that such a map provides solutions to the functional dynamical pentagon equation.

The flecnode polynomial: a central object in incidence geometry [PDF]
, 2014 We give a brief exposition of the proof of the Cayley-Salmon theorem and its recent role in incidence geometry. Even when we don't use the properties of ruled surfaces explicitly, the regime in which we have interesting results in point-line incidence ...

Parametric investigation of laser incidence geometry in laser-assisted milling of Inconel 718
Journal of Materials Research and TechnologyWhile laser-assisted milling machining is promising for promoting the machinability of Inconel 718, the geometrical parameters of laser beam relative to milling tool significantly influence its machining performance.

Incidence geometry in a Weyl chamber II: SLn
Advances in Applied Mathematics, 2020 We study the central hyperplane arrangement whose hyperplanes are the vanishing loci of the weights of the first and the second fundamental representations of $\mathfrak{gl}_n$ restricted to the dual fundamental Weyl chamber. We obtain generating functions that count flats and faces of a given dimension.

Versatile X-ray reflector extension setup for grazing-incidence experiments at SAXS facilities for liquid surface study [PDF]
Journal of Synchrotron RadiationExisting beamlines for in situ grazing-incidence small-angle scattering on liquids are either limited in angular range or incompatible with the large sample–detector distance required for submicrometre resolution.

On the Finite Field Cone Restriction Conjecture in Four Dimensions and Applications in Incidence Geometry [PDF]
International mathematics research notices, 2020 The first purpose of this paper is to solve completely the finite field cone restriction conjecture in four dimensions with $-1$ non-square. The second is to introduce a new approach to study incidence problems via restriction theory.

Velocity Increment on Incidence Angle near the Leading Edge of the Compressor Cascade
Aerospace, 2023 The geometry of a compressor leading edge has an important effect on the aerodynamic performance at an off-designed incidence angle. The current geometric design methods of the leading edge are usually developed based on the flow characteristics at the ...

EFFICIENT SPATIO-TEMPORAL MODELLING TO ENABLE TOPOLOGICAL ANALYSIS [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 Time-dependent analysis scenarios such as heat, wind or flood analysis in cities and in landscapes need a correct and consistent modelling of geometry and topology over time.
