THE HYPERBOLOID OF REVOLUTION OF ONE NAPPE A RULED SURFACE GENERATING CONICS
Journal of Industrial Design and Engineering Graphics, 2013 The paper intends to underline the property of the hyperboloid of revolution of one nappe to generate on its surface, when it is cut by a plane, the three known conics (ellipse, hyperbola and parabola).Cutting this surface by a plane, we find the ...

Ultraspinning limits and rotating hyperboloid membranes
Nuclear Physics B, 2016 We apply the hyperboloid membrane limit to the general Kerr-AdS metrics and their recently studied super-entropic cousins and obtain a new class of rotating black holes, for which the rotational parameters in multiple directions attain their maximal ...

HYPERBOLIC SUSPENDED GREENHOUSES
Journal of Industrial Design and Engineering Graphics, 2022 Agriculture is one of the most important economical branches that supports and develops our society. With the increased surface allocated for the urban areas, in order to create more space for agriculture purposes, one idea is to look up. Therefore, the

Small Science, Volume 6, Issue 3, March 2026.Core–shell alloy‐based BaTiO3/Au–Cu–Co–Ni vertically aligned nanocomposites exhibit tunable nanopillar morphologies governed by interfacial energetics. A temperature–time–transformation diagram predicts nanopillar evolution, while structure–property relationships link morphology with controllable optical anisotropy, hyperbolic dispersion, magnetic ...

A Cassegrain Antenna With Field-Controlled Reconfigurable Subreflector for HIRF Protection
IEEE Open Journal of Antennas and PropagationThis paper proposed a Cassegrain antenna with a field-controlled reconfigurable subreflector for high-intensity radiation fields (HIRF) protection. By replacing the rotating hyperboloid subreflector with a field-controlled reconfigurable metasurface, the

Research on Energy Regeneration Characteristics of Multi-Link Energy-Fed Suspension
EnergiesInspired by the single-blade hyperboloid, a new type of multi-bar shock absorber was designed, which can recover vibration energy. Its principle is to convert the droop reciprocating vibration of the vehicle in the spatial domain into the reciprocating ...
