Stochastic axial compressor variable geometry schedule optimisation [PDF]
, 2011 The design of axial compressors is dictated by the maximisation of flow efficiency at on design conditions whereas at part speed the requirement for operation stability prevails.

Stochastic geometry and topology of non-Gaussian fields. [PDF]
Proc Natl Acad Sci U S A, 2012 Gaussian random fields pervade all areas of science. However, it is often the departures from Gaussianity that carry the crucial signature of the nonlinear mechanisms at the heart of diverse phenomena, ranging from structure formation in condensed matter

Noncommutative geometry and stochastic processes [PDF]
, 2017 The recent analysis on noncommutative geometry, showing quantization of the volume for the Riemannian manifold entering the geometry, can support a view of quantum mechanics as arising by a stochastic process on it. A class of stochastic processes can be

Information Geometry of Nonlinear Stochastic Systems [PDF]
Entropy, 2018 We elucidate the effect of different deterministic nonlinear forces on geometric structure of stochastic processes by investigating the transient relaxation of initial PDFs of a stochastic variable x under forces proportional to -xn (n=3,5,7) and ...

Homogenization in Stochastic Differential Geometry
Publications of the Research Institute for Mathematical Sciences, 1981 It is well known that a diffusion process on Euclidean space can be rigorously considered as the limit of a sequence of transport processes. This idea, which dates at least to Rayleigh's problem of random flight [3] has now received a general treatment by modern probabilistic methods [2, 10].

Dimensional flow and fuzziness in quantum gravity: Emergence of stochastic spacetime
Nuclear Physics B, 2017 We show that the uncertainty in distance and time measurements found by the heuristic combination of quantum mechanics and general relativity is reproduced in a purely classical and flat multi-fractal spacetime whose geometry changes with the probed ...

U-statistics in stochastic geometry [PDF]
, 2015 This survey will appear as a chapter of the forthcoming book [19]. A U-statistic of order $k$ with kernel $f:\X^k \to \R^d$ over a Poisson process is defined in \cite{ReiSch11} as$$ \sum\_{x\_1, \dots , x\_k \in \eta^k\_{\neq}} f(x\_1, \dots, x\_k ...

Stochastic Time Evolution, Information Geometry, and the Cramér-Rao Bound [PDF]
Physical Review X, 2020 We investigate the connection between the time evolution of averages of stochastic quantities and the Fisher information and its induced statistical length.

On muting mobile terminals for uplink interference mitigation in HetNets—system-level analysis via stochastic geometry [PDF]
EURASIP Journal on Wireless Communications and Networking, 2019 We investigate the performance of a scheduling algorithm where the mobile terminals (MTs) may be turned off if they cause a level of interference greater than a given threshold.

Optimal Design for One-Dimensional ALOHA Ad Hoc Networks Based on Stochastic Geometry
International Journal of Distributed Sensor Networks, 2015 The aims of this paper are to analyze the performance of a one-dimensional ALOHA ad hoc network and to investigate the impact of the access probability of the ALOHA protocol on the network performance.
