Comparative Analysis of Steel Reinforced and Bamboo Reinforced Beams
Rekayasa Sipil, 2019 This research will seek to compare bamboo reinforced concrete beams and steel reinforced concrete beams experimentally. Special emphasis will be laid on how both sets of beams respond to nominal moments.

Advanced Engineering Materials, EarlyView.The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

, 2003 At the interaction point of a particle accelerator, various phenomena occur which are known as beam-beam effects. Incident bunches of electrons (or positrons) experience strong electromagnetic fields from the opposing bunches, which leads to electron deflection, beamstrahlung and the creation of electron/positron pairs and hadrons due to two-photon ...

Theoretical and numerical analysis of reinforced concrete beams with confinement reinforcement
Revista IBRACON de Estruturas e MateriaisThis paper discusses the use of confinement in over-reinforced concrete beams. This reinforcement consists of square stirrups, placed in the compression zone of the beam cross-section, in order to improve its ductility.

Behaviour under cyclic loading of strengthened beams
Revista IBRACON de Estruturas e Materiais, 2017 This work presents a study on the behavior of reinforced concrete beams strengthened in bending by the addition of concrete and steel on their tension side and having expansion bolts as shear connectors at the junction between the beam and the jacket ...

Revisit of combined parallel‐beam/cone‐beam or fan‐beam/cone‐beam imaging [PDF]
Medical Physics, 2013 Purpose:This aim of this paper is to revisit the parallel‐beam/cone‐beam or fan‐beam/cone‐beam imaging configuration, and to investigate whether this configuration has any advantages.Methods:Twenty years ago, it was suggested to simultaneously use a parallel‐beam (or a fan‐beam) collimator and a cone‐beam collimator to acquire single photon emission ...
