Electromagnetohydrodynamic (EMHD) Flow in a Microchannel with Random Surface Roughness [PDF]
Micromachines, 2023 This study investigates the effect of small random transverse wall roughness on electromagnetohydrodynamic (EMHD) flow is in a microchannel, employing the perturbation method based upon stationary random function theory.

Random Surfaces with Boundary [PDF]
Discrete & Computational Geometry, 2021 A surface with boundary is randomly generated by gluing polygons along some of their sides. We show that its genus and number of boundary components asymptotically follow a bivariate normal distribution.

Relationship between Surface Roughness and Touch Perception on the Surfaces with Randomly Spaced, Irregular Features [PDF]
한국정밀공학회지, 2021 The objective of the present study was to investigate the relationship between surface roughness and touch perception of surfaces with randomly spaced, irregular features. Two sets of specimens with top surfaces consisting of triangular peaks and valleys

The diameter of random Belyĭ surfaces [PDF]
Algebraic & Geometric Topology, 2021 We determine the asymptotic growth rate of the diameter of the random hyperbolic surfaces constructed by Brooks and Makover. This model consists of a uniform gluing of $2n$ hyperbolic ideal triangles along their sides followed by a compactification to get a random hyperbolic surface of genus roughly $n/2$.

Application of random forest for modelling of surface water salinity
Ain Shams Engineering Journal, 2022 Modeling surface water quality using artificial intelligence-based models is essential in projecting suitable mitigation measures. However, it remains a challenge and requires further research to enhance the modeling accuracy.

Probability Theory and Related Fields, 2023 We study how the typical gradient and typical height of a random surface are modified by the addition of quenched disorder in the form of a random independent external field. The results provide quantitative estimates, sharp up to multiplicative constants, in the following cases.

Surface passivation of random alloy AlGaAsSb avalanche photodiode
Electronics Letters, 2023 AlGaAsSb attracts significant interest for near‐infrared avalanche photodiodes (APD). The authors report a two‐order reduction in the dark current and a six‐time enhancement of gain in random alloy (RA) AlGaAsSb APD that is surface passivated by ...

Machine Learning Methods for the Prediction of Abraded Butadiene-Styrene Rubber Surface Roughness
Medžiagotyra, 2023 The aim of this investigation was to evaluate the ability to predict the roughened surface area of soft polymeric materials using the machine learning method. Random forest and extremely random forest machine learning methods have been applied to predict

The Evolution of Random Graphs on Surfaces [PDF]
SIAM Journal on Discrete Mathematics, 2017 For integers $g,m \geq 0$ and $n>0$, let $S_{g}(n,m)$ denote the graph taken uniformly at random from the set of all graphs on $\{1,2, \ldots, n\}$ with exactly $m=m(n)$ edges and with genus at most $g$. We use counting arguments to investigate the components, subgraphs, maximum degree, and largest face size of $S_{g}(n,m)$, finding that there is ...
