Behavior of Quarry Rock Dust, Fly Ash and Slag Based Geopolymer Concrete Columns Reinforced with Steel Fibers under Eccentric Loading

open access: yesApplied Sciences, 2021
Geopolymer concrete, also known as an earth-friendly concrete, has been under continuous study due to its environmental benefits and a sustainable alternative to conventional concrete construction.

A New Analytical Method for Modeling the Effect of Assembly Errors on a Motor-Gearbox System

open access: yesEnergies, 2021
The well-known gear tooth defects such as root cracks and flank spalls have been widely investigated in previous studies to model their effects on the time varying mesh stiffness (TVMS) and consequently the dynamic response of motor-gearbox systems ...

Laplacian Energy and Eccentricity Based Energy for Cross Monic Zero Divisor Graph Associated With Commutative Rings

open access: yesمجلة بغداد للعلوم
For a commutative ring, a cross monic zero divisor graph is discussed, whose vertices are nonzero zero divisors of the commutative ring, then the two vertices x and y are adjacent if and only if xy = 0.

The Effects of Spatial Endogenous Pre-cueing across Eccentricities

open access: yesFrontiers in Psychology, 2017
Frequently, we use expectations about likely locations of a target to guide the allocation of our attention. Despite the importance of this attentional process in everyday tasks, examination of pre-cueing effects on attention, particularly endogenous pre-

Regional Variation of Gap Junctional Connections in the Mammalian Inner Retina

open access: yesCells, 2021
The retinas of many species show regional specialisations that are evident in the differences in the processing of visual input from different parts of the visual field.

Impact of 3D air gap eccentricity on winding insulation temperature characteristic in PMSG

open access: yesAlexandria Engineering Journal
The static air gap eccentricity is one of the prevalent faults in permanent magnet synchronous generators. In previous studies, the variation of magnetic flux density, stator current and vibration have been studied mostly.

Evaluation of the electrodynamic forces in high-speed permanent magnet machines with rotor eccentricity

open access: yesMechanical Engineering Journal, 2017
In permanent magnet motors, the presence of rotor eccentricities can alter the airgap field distribution. This results in parasitic radial detent forces that can be reduced by connecting the stator phases in parallel.

Nonlinear Analysis of Hollow Slender Reinforced Concrete Columns Subjected to Concentric and Eccentric Loads

open access: yesCivil and Environmental Engineering, 2022
This paper investigates the load capacity and failure modes of slender hollow RC column under axial and eccentric loads. For the slender hollow columns, different load eccentricities and hole shapes are used. The finite element software ABAQUS is used to
