Small Scale Problems of the ΛCDM Model: A Short Review

open access: yesGalaxies, 2017
The ΛCDM model, or concordance cosmology, as it is often called, is a paradigm at its maturity. It is clearly able to describe the universe at large scale, even if some issues remain open, such as the cosmological constant problem, the small-scale ...

Stochastic Modelling of Small-Scale Perturbation [PDF]

open access: yesWater, 2020
In this paper we propose a stochastic model reduction procedure for deterministic equations from geophysical fluid dynamics. Once large-scale and small-scale components of the dynamics have been identified, our method consists in modelling stochastically the small scales and, as a result, we obtain that a transport-type Stratonovich noise is sufficient

Experimental Analysis of the Behaviour of Piled Raft Foundations in Loose Sand

open access: yesApplied Sciences, 2022
This paper presents the experimental analysis that was conducted on small-scale 1g physical models of piled raft foundation structures with a group of 2 × 2 piles in loose sand. The purpose of the piles was to reduce the settlement of the raft.

GC-YOLOv5s: A Lightweight Detector for UAV Road Crack Detection

open access: yesApplied Sciences, 2023
This study proposes a GC-YOLOv5s crack-detection network of UAVs to work out several issues, such as the low efficiency, low detection accuracy caused by shadows, occlusions and low contrast, and influences due to road noise in the classic crack ...

The detection and diagnosis model for small scale MSLB accident

open access: yesNuclear Engineering and Technology, 2021
The main steam line break accident is an essential initiating event of the pressurized water reactor. In present work, the fuzzy set theory and the signal-based fault detection method has been used to detect the occurrence and diagnosis of the location ...

Einstein clusters as models of inhomogeneous spacetimes [PDF]

open access: yes, 2020
We study the effect of small-scale inhomogeneities for Einstein clusters. We construct a spherically symmetric stationary spacetime with small-scale radial inhomogeneities and propose the Gedankenexperiment.
