Arrays of optical vortices formed by "fork" holograms [PDF]
, 2014 Singular light beams with optical vortices (OV) are often generated by means of thin binary gratings with groove bifurcation ("fork holograms") that produce a set of diffracted beams with different OV charges. Usually, only single separate beams are used

Complex Light and Optical Forces XV, 2020 We show that a class of vector vortex beams possesses a topological property that derives both from the spatially varying amplitude of the field and also from its varying polarization.

On the Detection of Fracture within Vibrating Beams Traversed by a Moving Force
Infrastructures, 2022 In this work, we examine the influence of a crack in the span of a beam as it is being traversed by a point force with constant velocity. This problem presents two types of discontinuities: one spatial, where the crack is modelled as a discontinuity in ...

Beam-beam effects in RHIC [PDF]
, 2012 In this article we review the beam-beam effects in the polarized proton runs in the Relativistic Heavy Ion Collider (RHIC). The operational observations, limitations, and the next luminosity goal are presented and discussed. With an upgraded polarized proton source, the proton bunch intensity will be increased from 1.7 × 10 up to 3.0 × 10.

Concept for controlled transverse emittance transfer within a linac ion beam [PDF]
, 2011 For injection of beams into circular machines with different horizontal and vertical emittance acceptance, the injection efficiency can be increased if these beams are flat, i.e. if they feature unequal transverse emittances.

Free-space information transfer using light beams carrying orbital angular momentum.
Optics Express, 2004 We demonstrate the transfer of information encoded as orbital angular momentum (OAM) states of a light beam. The transmitter and receiver units are based on spatial light modulators, which prepare or measure a laser beam in one of eight pure OAM states ...

SHEAR CAPACITY OF REINFORCED CONCRETE BEAMS WITHOUT SHEAR REINFORCEMENT: A REVIEW
Journal of Engineering and Sustainable Development, 2023 Shear failure in reinforced concrete beams has gained excessive study, particularly beams without stirrups. Because shear failure is considered the most serious due to it occurring suddenly without warning.

Flexural Behavior of Reinforced Concrete Beams Covered by Gypsum Layers and Exposed to Elevated Temperatures [PDF]
E3S Web of Conferences, 2021 The paper presents results of exposure of normal concrete to elevated temperatures (400 and 700) °C covered by layers (gypsum and plaster) with different thicknesses (10 and 20) mm.
