Identification of arches in 2D granular packings [PDF]
Phys. Rev. E 74, 021303 (2006), 2006 We identify arches in a bed of granular disks generated by a molecular dynamic-type simulation. We use the history of the deposition of the particles to identify the supporting contacts of each particle. Then, arches are defined as sets of mutually stable disks. Different packings generated through tapping are analyzed.

Network log-ARCH models for forecasting stock market volatility [PDF]
arXiv, 2023 This paper presents a novel dynamic network autoregressive conditional heteroscedasticity (ARCH) model based on spatiotemporal ARCH models to forecast volatility in the US stock market. To improve the forecasting accuracy, the model integrates temporally lagged volatility information and information from adjacent nodes, which may instantaneously spill ...

Probabilistic assessment of the impact of material properties on the risk of frost damage in masonry constructions [PDF]
MATEC Web of Conferences, 2019 Historically valuable buildings often contain a huge energy saving potential due to their current lacking thermal performance of the building envelope. Next to this, unfortunately insulation measures, which normally occur at the inside, induce a decrease

On arch factorization and subword universality for words and compressed words [PDF]
arXiv, 2023 Using arch-jumping functions and properties of the arch factorization of words, we propose a new algorithm for computing the subword circular universality index of words. We also introduce the subword universality signature for words, that leads to simple algorithms for the universality indexes of SLP-compressed words.

Arch-based configurations in the volume ensemble of static granular systems [PDF]
, 2014 We propose an alternative approach to count the microscopic static configurations of granular packs under gravity by considering arches. This strategy simplifies the problem of filtering out configurations that are not mechanically stable, opening the way for a range of granular models to be studied via ensemble theory.
