Acoustic Wavefront Shaping Using Ultrahigh Phase Resolution Metamaterial

Advanced Materials Technologies, Volume 10, Issue 22, November 19, 2025.
A Bilateral Symmetrical T‐shaped (BST) acoustic metamaterial unit cell capable of achieving a high phase resolution of π/36 radians at 8000 Hz is introduced. The approach enables tunable wavefront control through simple rotational adjustment of BST, which offers an alternative to the conventional complex metamaterials unit cell design and a way for ...

Delay Discounting and Teacher Decision‐Making of Behavioral Interventions

Behavioral Interventions, Volume 40, Issue 4, November 2025.
ABSTRACT This paper presents two studies that used delay discounting to understand how teachers of students who engage in challenging behavior discount delays in behavioral treatment outcomes. In Experiment 1, the authors administered the monetary choice questionnaire (MCQ) to assess discounting of monetary rewards and a treatment choice questionnaire (

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 Gravitation
AbstractWe 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 Propagation
This 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 ...

Folding of Fuzzy Hyperboloid

Indian Journal of Science and Technology, 2013
Our aim in the present paper is to introduce and study new connection between fuzzy retractions, fuzzy foldings and fuzzy deformation retracts of fuzzy open hyperboloid in fuzzy Minkowski space and fuzzy open ball in fuzzy Euclidean space. Types of fuzzy foldings and fuzzy deformation retracts of fuzzy open hyperboloid are discussed.

Research on Energy Regeneration Characteristics of Multi-Link Energy-Fed Suspension

Energies
Inspired 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 ...

Separation of Variables and Contractions on Two-Dimensional Hyperboloid

Symmetry, Integrability and Geometry: Methods and Applications, 2012
In this paper analytic contractions have been established in the R→∞ contraction limit for exactly solvable basis functions of the Helmholtz equation on the two-dimensional two-sheeted hyperboloid. As a consequence we present some new asymptotic formulae.
