Dark Matter Substructure within Galactic Halos [PDF]

open access: yes, 1999
We use numerical simulations to examine the substructure within galactic and cluster mass halos that form within a hierarchical universe. Clusters are easily reproduced with a steep mass spectrum of thousands of substructure clumps that closely matches ...

INFLUENCE OF PLASTIC DEFORMATION CARBON STEEL ON THE PROCESS OF BURNING ELECTRIC ARC [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2021
During a study of the combustion process of a direct polarity electric arc, a directly proportional dependence of the electric current value on the degree of cold plastic deformation of carbon steel used as an electrode was found.

Jet substructure at the Large Hadron Collider: A review of recent advances in theory and machine learning [PDF]

open access: yesPhysics reports, 2017
Jet substructure has emerged to play a central role at the Large Hadron Collider (LHC), where it has provided numerous innovative new ways to search for new physics and to probe the Standard Model in extreme regions of phase space.

Additive manufacturing introduced substructure and computational determination of metamaterials parameters by means of the asymptotic homogenization [PDF]

open access: yesContinuum Mechanics and Thermodynamics, 2020
Metamaterials exhibit materials response deviation from conventional elasticity. This phenomenon is captured by the generalized elasticity as a result of extending the theory at the expense of introducing additional parameters.

‘Telephone Triage’: a possible means of managing the after-hours patient load at primary health care facilities in South Africa

open access: yesSouth African Family Practice, 2018
The rate at which routine patients are using the emergency department (ED) as a path to enter into the healthcare system in South Africa’s community healthcare facilities and district hospitals is alarming.

Evaluation of the Progressive Collapse of the Reinforced Concrete Frames Considering the Soil–Structure Interaction: Parametric Study Based on the Sensitivity Index

open access: yesInternational Journal of Concrete Structures and Materials, 2022
In this essay, to investigate the progressive collapse of the reinforced concrete (RC) frames, a nonlinear static pushdown analysis was performed with column removal scenarios from the first story.

SUBSTRUCTURES OF HOM

open access: yesJournal of Algebra and Its Applications, 2010
Let M and N be two modules over a ring R. The concern is about the four substructures of hom R(M, N): the Jacobson radical J[M, N], the singular ideal Δ[M, N], the co-singular ideal ∇[M, N] and the total Tot [M, N]. One natural question is to characterize when the total is equal to one or more of the other structures.

On dynamic analysis method for large-scale train–track–substructure interaction

open access: yesRailway Engineering Science, 2022
Train–track–substructure dynamic interaction is an extension of the vehicle–track coupled dynamics. It contributes to evaluate dynamic interaction and performance between train–track system and its substructures.

Causality in real-time dynamic substructure testing [PDF]

open access: yes, 2009
Causality, in the bond graph sense, is shown to provide a conceptual framework for the design of real-time dynamic substructure testing experiments. In particular, known stability problems with split-inertia substructured systems are reinterpreted as ...
