Analytical modeling of one problem of the quasiareal infinitesimal deformation of the surface
Pracì Mìžnarodnogo Geometričnogo Centru, 2015 In this paper the object of study is the quasiareal infinitesimal deformation of the unrestricted simply connected regular surface of non-zero the Gauss curvature, provided that under this deformation the deviation of the surface from the tangent plane ...

A two-dimensional random crystalline algorithm for Gauss curvature flow [PDF]
, 2002 We propose and study a random crystalline algorithm (a discrete approximation) of the Gauss curvature flow of smooth simple closed convex curves in R2 as a stepping stone to the full understanding of such phenomena as the wearing process of stones on a ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.The climatological‐error covariance matrix used in three‐dimensional variational data assimilation (3DVar) provides smooth and isotropic increments spread to long distances. In contrast, three‐dimensional ensemble variational data assimilation (3DEnVar) with a purely ensemble‐error covariance matrix provides inhomogeneous increments and contains the ...

, 2016 The Gauss map maps the unit normal of a surface (on the right) to the unit sphere (on the left). The area surrounding the point on the surface is thus mapped to an area on the unit sphere.

A Novel Approach to Energy Management in Electric Steelworks
steel research international, EarlyView.Feed‐forward neural networks are exploited to estimate electric energy consumptions of the electric arc furnace and ladle furnace processes. The models are used to optimize production schedule so that more energy intensive grades are produced when the cost of energy is lower.

Structural Concrete, EarlyView.Abstract Post‐earthquake fires pose a significant threat to urban environments, with potentially catastrophic consequences for buildings and infrastructure. To enhance understanding and mitigate these risks, this study conducts a comparative analysis of post‐earthquake fire (PEF) in two‐dimensional (2D) and three‐dimensional (3D) reinforced concrete ...

The capillary Gauss curvature flow
In this article, we first introduce a Gauss curvature type flow for capillary hypersurfaces, which we call capillary Gauss curvature flow. We then show that the flow will shrink to a point in finite time. This is a capillary counterpart (or Robin boundary counterpart) of Firey's problem studied in [Mathematika 21 (1974), pp. 1-11] and Tso [Comm.

A Robust Visual Inertial Odometry SLAM Considering Robot Self Dynamics
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT In this paper, to deal with the dynamic SLAM problem, we investigate feature tracking and IMU preintegration in visual‐inertial odometry (VIO) and design a robust SLAM framework that explicitly considers robot self‐dynamics. We propose a self‐dynamics and IMU‐aided feature tracker to predict initial optical flow and an iterative refinement ...
