Gravitational lensing by a Horndeski black hole

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
In this article we study gravitational lensing by non-rotating and asymptotically flat black holes in Horndeski theory. By adopting the strong deflection limit, we calculate the deflection angle, from which we obtain the positions and the magnifications ...

Peak Response Prediction for RC Beams under Impact Loading

open access: yesShock and Vibration, 2019
In this paper, a novel and simple method for predicting the peak response of RC beams subjected to impact loading is proposed. The theoretical basis for calculating the peak impact force originates from the contact law, the principle of conservation of ...

An Integrated Machine Learning Algorithm for Separating the Long-Term Deflection Data of Prestressed Concrete Bridges

open access: yesSensors, 2018
Deflection is one of the key indexes for the safety evaluation of bridge structures. In reality, due to the changing operational and environmental conditions, the deflection signals measured by structural health monitoring systems are greatly affected ...

Coherent control of high efficiency metasurface beam deflectors with a back partial reflector

open access: yesAPL Photonics, 2017
Recently, coherent control of absorption in metallic metasurfaces has been demonstrated, and this phenomenon was applied to intriguing light-by-light switching operation. Here we experimentally demonstrate coherent control

Comparison of Mechanical Properties Between three Different Types of T-loop

open access: yesJournal of Dental Biomaterial, 2015
Statement of Problem: T-loop is one of the most popular closing loops in orthodontic profession. However its activation is in the contrary to Bouschinger effect theory, since the formed bends would be opened during activation.
