Stadiums based on curvilinear geometry: Approximation of the ellipsoid offset surface

open access: yesOpen Engineering, 2022
This article provides an effective method of determining the coordinates of points and the angles for various surfaces approximating the ellipsoid surface. The stands of the stadium (with a capacity of up to 82,000 seats) with rows shaped by ellipse arcs

Quantum steering ellipsoids, extremal physical states and monogamy [PDF]

open access: yes, 2014
A Corrigendum for this article has been published in 2015 New J. Phys. 17 019501Any two-qubit state can be faithfully represented by a steering ellipsoid inside the Bloch sphere, but not every ellipsoid inside the Bloch sphere corresponds to a two-qubit ...

Ellipsoids (v1.0): 3-D magnetic modelling of ellipsoidal bodies [PDF]

open access: yesGeoscientific Model Development, 2017
Abstract. A considerable amount of literature has been published on the magnetic modelling of uniformly magnetized ellipsoids since the second half of the nineteenth century. Ellipsoids have flexibility to represent a wide range of geometrical forms, are the only known bodies which can be uniformly magnetized in the presence of a uniform inducing field

Effect of roughness on the conductivity of vacuum coated flexible paper electrodes

open access: yesNano Select, 2021
Flexible conducting materials are required for the design and fabrication of a host of applications involving flexible electronic items. A flexible substrate like paper or polymer is generally employed for deposition of metal by a variety of processes ...

On a possible connection between Chandler wobble and dark matter [PDF]

open access: yes, 2009
Chandler wobble excitation and damping, one of the open problems in geophysics, is treated as a consequence in part of the interaction between Earth and a hypothetical oblate ellipsoid made of dark matter.

Electromagnetic imaging of ellipsoids and ellipsoidal bosses [PDF]

open access: yesThe Quarterly Journal of Mechanics and Applied Mathematics, 1998
This paper considers the inverse scattering problem to determine the geometrical characteristics of a perfectly conducting ellipsoid or ellipsoidal boss from the first coefficient in the low frequency expansion of the scattering amplitude. For the ellipsoid, measurements corresponding to six directions of incidence are sufficient to determine ...

Orlicz–John ellipsoids

open access: yesAdvances in Mathematics, 2014
Let \(\varphi:[0,\infty)\to[0,\infty)\) be a strictly increasing, convex function with \(\varphi(0)=0\). The \textit{normalized Orlicz mixed volume} (regarding \(\varphi\)) of the convex bodies \(K,L\subset {\mathbb R}^n\) containing \(0\) in the interior is defined by \[ \overline{V}_\varphi(K,L)= \varphi^{-1}\left(\frac{1}{n|K|} \int_{S^{n-1 ...

The N-Vortex Problem on a Symmetric Ellipsoid: A Perturbation Approach

open access: yes, 2007
We consider the N-vortex problem on a ellipsoid of revolution. Applying standard techniques of classical perturbation theory we construct a sequence of conformal transformations from the ellipsoid into the complex plane.

Reachable Set Estimation and Controller Design for Linear Time-Delayed Control System with Disturbances

open access: yesMathematics
This paper investigates reachable set estimation and state-feedback controller design for linear time-delay control systems with bounded disturbances. By constructing an appropriate Lyapunov–Krasovskii functional, we obtain a delay-dependent condition ...

FRACTIONATION OF GRAIN MATERIALS: METHOD JUSTIFICATION [PDF]

open access: yesТехника и технология пищевых производств, 2016
The need to organize waste-free use of recyclable milk raw is due to its adverse environmental effects when released as part of waste water and the presence in it of valuable food components, which can be used in main production.
