Bond durability and service life prediction of BFRP bars to steel FRC under aggressive environmental conditions
(
Elsevier
, 2021 , Article)
This study presents an experimental investigation on the bond durability of helically wrapped basalt fiber reinforced polymer (BFRP) bars embedded in plain and steel fiber reinforced concrete (SFRC) under the combined ...
Parametric Estimation from Empirical Data Using Particle Swarm Optimization Method for Different Magnetorheological Damper Models
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
The nonlinearity behaviour of magnetorheological fluid (MRF) can be described using a number of established models such as Bingham and Modified Bouc-Wen models. Since these models require the identification of model ...

In addition to its canonical functions, vitamin D has been proposed to be an important mediator of the immune system. Despite ample sunshine, vitamin D deficiency is prevalent (>80%) in the Middle East, resulting in a high ...
Some α − ϕ-Fuzzy Cone Contraction Results with Integral Type Application
(
Hindawi Limited
, 2021 , Article)
In this paper, we define α-admissible and α-ϕ-fuzzy cone contraction in fuzzy cone metric space to prove some fixed point
theorems. Some related sequences with contraction mappings have been discussed. Ultimately, our ...
