A New Approach to the Accretive Growth of Surfaces Via Hyperbolical Kinematics
Mathematical Methods in the Applied Sciences, Volume 48, Issue 16, Page 15349-15363, 15 November 2025.ABSTRACT In the current work, we introduce the accretive growth of surfaces by using hyperbolical geometry. First, we describe hyperbolical kinematics along a generating curve to construct accretive surfaces having a hyperbolical cross‐section. The obtained surfaces are not only the ones having hyperbolical cross‐sections but also their material points

A Gauge Field Theory for Continuous Spin Tachyons
, 2018 We present a gauge field theory for unitary infinite dimensional tachyonic representations of the Poincar\'e group. It was obtained by a dimensional reduction from the gauge field theory for continuous spin particles in a cotangent bundle over Minkowski ...

Study of flow around model of cooling tower by means of 2D Particle Image Velocimetry measurement
EPJ Web of Conferences, 2017 This paper deals with flow around a bluff body of hyperboloid shape. It combines results gathered in the course of research by means of Particle Image Velocimetry (PIV).

The d’Alembert solution in hyperboloidal foliations
General Relativity and GravitationAbstractWe explicitly construct the analogue of the d’Alembert solution to the 1+1 wave equation in an hyperboloidal setting. This hyperboloidal d’Alembert solution is used, in turn, to gain intuition into the behaviour of solutions to the wave equation in a hyperboloidal foliation and to explain an apparently anomalous permanent displacement of the ...

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

Spectroscopic sensor for measuring omnidirectional area in two-dimensional plane
Nihon Kikai Gakkai ronbunshu, 2014 This paper describes a spectroscopic sensor for measuring a wavelength of the light from objects in two-dimensional omnidirectional area. I developed the spectroscopic sensor, in which vertical slits, a horizontal slit, a cylindrical reflective grating ...
