Influence of Fracture Volumetric Intensity on Strength Anisotropy of Foliated Rock Masses: Insights From a Synthetic Rock Mass Modeling Approach

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This paper presents a synthetic rock mass (SRM) methodology to investigate the influence of fracture volumetric intensity (P32$P_{32}$) on the strength anisotropy of foliated rock masses containing non‐persistent fracture sets. The approach integrates UAV‐based discontinuity mapping, discrete fracture network (DFN) modeling, and lattice‐spring

Hybrid STATCOM–Capacitor–DER Framework for Advanced Power Factor Correction and Efficiency Enhancement in 33 kV Distribution Networks

Journal of High-Frequency Communication Technologies
Power factor correction (PFC) remains a critical requirement in medium-voltage (MV) distribution networks, particularly at the 33 kV level, where high reactive power demand and increased integration of distributed energy resources (DERs) lead to ...

Automatic Power Factor Correction Using PLC

, 2018
Power factor correction (PFC) is a technique of counteracting the undesirable effects of electric loads that create a power factor that is less than one. Power factor correction may be applied either by an electrical power transmission utility to improve

Power factor correction using parallel boost converter [PDF]

, 2011
The increased use of power electronic devices has declined the power quality in terms of introduction of harmonics and lowering of power factor.This is due to their non-linear nature of operation.

Chromatin Accessibility Profiling of the Canine Brain Reveals Regulatory Programs Associated With Dog‐Wolf Divergence and Human Psychiatric Risk

Integrative Zoology, EarlyView.
The dog is a valuable model for studying social behavior and neuropsychiatric disease. We generated an ATAC‐seq atlas of 7 brain regions and pituitary from 4 beagles, identifying 251,492 CREs. Integrating dog‐wolf divergence revealed tissue‐specific CREs overlapping divergent loci, including neuronal and neuroendocrine genes.

Towards Credible GHG Reporting: The Role of GHG Assurance and Assurance Providers in Firm Valuation

Abacus, EarlyView.
The demand for greenhouse gas (GHG) emissions disclosures is rising globally; yet, the credibility of such information remains uncertain when assurance is not mandated. Drawing on a sample of firms from 43 countries, this study examines the role of GHG assurance and the choice of assurance provider in the market value effects of GHG emissions.
