Increase of Snow Compaction Density by Repeated Artificial Snow Consolidation Formation

Journal of the Institute of Industrial Applications Engineers, 2020
A method to consolidate huge amounts of snow into large ice pieces has been investigated based on science viewpoints for supporting the maintenance of road infrastructure in winter [1]. This study investigated repeated artificial snow consolidation formation for increasing snow compaction density. Producing compacted snow having density exceeding ρ = 0.

Contact Lens Knowledge and Practices Among Students in the College of Health Sciences, University of Ghana: A Cross‐Sectional Study

Eye &ENT Research, EarlyView.
ABSTRACT Background Contact lenses (CLs) are increasingly used worldwide for refractive error correction because of their optical, cosmetic, and functional advantages over spectacles. However, although their safe and effective use depends on adequate knowledge and proper hygiene practices, there is limited evidence on contact lens‐related knowledge ...

Self‐Supervised Coherence‐Based Denoising of Cryoseismological Distributed Acoustic Sensing Data

Journal of Geophysical Research: Machine Learning and Computation
A major challenge in cryoseismology is that signals of interest are often buried within the high noise level emitted by a variety of environmental processes. Particular Distributed Acoustic Sensing (DAS) data often suffers from low signal‐to‐noise ratios

Evaluation of the Adequacy of Design Specifications for Nonstructural Components in a Reticular Structure

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Nonstructural components (NSCs) installed in large‐span reticular structures were frequently severely damaged during earthquakes, even when the primary structure remained intact. Existing seismic design specifications for NSCs were predominantly developed for upright structures such as multi‐storey buildings and offer no guidance for reticular

Hydrological Implications of Covering Wind-Blown Snow Accumulations with Geotextiles on Mount Aragats, Armenia

Geosciences, 2014
Snow is an excellent water reservoir, naturally storing large quantities of water at time scales from a few days to several months. In summer-dry countries, like Armenia, runoff due to snow melt from mountain regions is highly important for a sustained ...

Comparative Assessment and Benchmarking of Metaheuristic Algorithms for Dynamic Photovoltaic Array Reconfiguration Under Diverse Shading Environments

Energy Science &Engineering, EarlyView.
ABSTRACT The solar photovoltaic (PV) installations, which are essential for renewable energy systems, are vulnerable to partial shading, resulting in considerable power losses and operational inefficiencies. The dynamic reconfiguration of PV arrays has become an effective strategy to mitigate these effects by adaptively modifying the array topology to ...
