Study on the Effect of the Position of X-bracing Arrangement in the Steel Structures with a Triangular Plan [PDF]

open access: yesNumerical Methods in Civil Engineering, 2017
In buildings with triangular plan, the center of mass and rigidity cannot geometrically match all possible directions of the earthquake. This will result in torsional moments in the stories causing the building to rotate around the center of rigidity. In

Behaviour of Slender Hybrid Rubberised Concrete Double Skin Tubular Columns under Eccentric Loading

open access: yesBuildings, 2023
Rubberised concrete, utilised as infill material within single- or double-skin confinements, has emerged as a sustainable solution, offering improved ductility in structures.

The exoplanet eccentricity distribution from Kepler planet candidates [PDF]

open access: yes, 2012
The eccentricity distribution of exoplanets is known from radial velocity surveys to be divergent from circular orbits beyond 0.1 au. This is particularly the case for large planets where the radial velocity technique is most sensitive.

TESS Giants Transiting Giants. III. An Eccentric Warm Jupiter Supports a Period − Eccentricity Relation for Giant Planets Transiting Evolved Stars [PDF]

open access: yes, 2023
The fate of planets around rapidly evolving stars is not well understood. Previous studies have suggested that, relative to the main-sequence population, planets transiting evolved stars (P < 100 days) tend to have more eccentric orbits.

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.

Eccentricity evolution of spinning binaries [PDF]

open access: yes, 2023
We study the evolution of the eccentricity of an eccentric orbit with spinning components. We develop a prescription to express the evolving eccentricity in terms of initial eccentricity and frequency.

The eccentricity-based topological indices

open access: yes, 2023
The aim of this paper is to obtain some relationships between eccentricity-based topological indices as the eccentric connectivity, connective eccentricity, total eccentricity, second Zagreb eccentricity, first Zagreb eccentricity connectivity, first ...

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-
