Flexural Strengthening of Continuous RC Beams Using HPFRCC Precast Laminates [PDF]
Journal of Structural and Construction Engineering, 2021 In this study, the use of precast laminates, made of high-performance fiber-reinforced cementitious composite (HPFRCC), was investigated for strengthening of continuous reinforced concrete (RC) beams.

Conditional transfer of quantum correlation in the intensity of twin beams [PDF]
, 2005 A conditional protocol of transferring quantum-correlation in continuous variable regime was experimentally demonstrated. The quantum-correlation in two pairs of twin beams, each characterized by intensity-difference squeezing of 7.0 dB, was transferred ...

Experimental demonstration of entanglement assisted coding using a two-mode squeezed vacuum state [PDF]
, 2004 We have experimentally realized the scheme initially proposed as quantum dense coding with continuous variables [Ban, J. Opt. B \textbf{1}, L9 (1999), and Braunstein and Kimble, \pra\textbf{61}, 042302 (2000)].

Serviceability Response of Rehabilitated Unbonded Post-tensioned Indeterminate I-Beams Consisting UHSSCC [PDF]
Journal of Rehabilitation in Civil Engineering, 2015 The ultra-high strength self-compacting concrete, UHSSCC is the new generation type of concrete with a compressive strength higher than 80MPa. The application of this type of concrete on the serviceability state in CFRP strengthened unbonded post ...

Ultimate Tendon Stress in CFRP Strengthened Unbounded HSC Post-Tensioned Continuous I-Beams [PDF]
Journal of Rehabilitation in Civil Engineering, 2014 The use of unbounded tendons is common in prestressed concrete structures and evaluation of the stress increase in unbonded tendons at ultimate flexural strength of such structure has posed a great challenge over the years.

Electron Beam Instability in Left-Handed Media [PDF]
, 2008 We predict that two electron beams can develop an instability when passing through a slab of left-handed media (LHM). This instability, which is inherent only for LHM, originates from the backward Cherenkov radiation and results in a self-modulation of ...

“Analytical continuation” of flattened Gaussian beams
Journal of the Optical Society of America A, 2023 A purely analytical extension of flattened Gaussian beams [Opt. Commun. 107, 335 (1994)OPCOB80030-401810.1016/0030-4018(94)90342-5] to any values of beam order is here proposed. Due to it, the paraxial propagation problem of axially symmetric, coherent flat-top beams through arbitrary ABCD optical systems can definitely be solved in closed form via a ...
