Effect of Wire-Mesh Type on Strengthening Reinforced Concrete Beams [PDF]
Engineering and Technology Journal, 2022 Structural strengthening is a method of application to raise the load-ability capacity of building structures to meet the building's need to carry additional and unexpected loads that were not accounted for in the main design. In this study, Ferro-cement

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 ...

Volkov solution for two laser beams and ITER [PDF]
, 2005 We find the solution of the Dirac equation for two plane waves (laser beams) and we determine the modified Compton formula for the scattering of two photons on an alectron.

Beam-Beam Simulations for Double-Gaussian Beams [PDF]
Proceedings of the 2005 Particle Accelerator Conference, 2006 Electron cooling together with intra-beam scattering results in a transverse distribution that can best be described by a sum of two gaussians, one for the high-density core and one for the tails of the distribution [1]. Simulation studies are being performed to understand the beam-beam interaction of these double-gaussian beams.

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 ...

Observation of self-accelerating Bessel-like optical beams along arbitrary trajectories [PDF]
, 2013 We experimentally demonstrate self-accelerating Bessel-like optical beams propagating along arbitrary trajectories in free space. With computer generated holography, such beams are designed to follow different controllable trajectories while their main ...

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.
