Fault diagnosis of large-scale electric pumping and irrigation electromechanical equipment by integrating CWT and swin transformer

Frontiers in Mechanical Engineering
This paper proposes a large-scale electromechanical equipment fault diagnosis framework that integrates continuous wavelet transform (CWT), Swin transformer, and cross attention. Firstly, CWT uses optimized complex Morlet wavelets (impact sharpness ratio

Hybrid photovoltaic-thermoelectric generator powered synchronous reluctance motor for pumping applications [PDF]

, 2019
The interest in photovoltaic (PV) pumping systems has increased, particularly in rural areas where there is no grid supply available. However, both the performance and the cost of the whole system are still an obstacle for a wide spread of this ...

Quantifying the impacts of groundwater abstraction on Ganges river water infiltration into shallow aquifers under the rapidly developing city of Patna, India

Journal of Hydrology: Regional Studies, 2022
Study region: Patna is located on the southern bank of the River Ganges in Bihar, India. Rapid population growth over the past few decades has driven an increase in groundwater abstraction from aquifers under the city.

Larval fish in the vicinity of aquaculture intakes [PDF]

, 1991
Texas Parks and Wildlife Department has recently proposed that all facilities pumping water from Texas estuaries be fitted with 0.5 mm screening to prevent larval fish mortality at these facilities. Data on larval fish distributions in Texas estuaries is

Investigating the Double-Fissure Interactions of Hydraulic Concrete Under Three-Point Bending: A Simulation Study Using an Improved Meshless Method

Buildings
Hydraulic concrete is prone to cracking and interactive propagation under complex stress, threatening its structural integrity and service life. To address limitations of traditional numerical methods (e.g., mesh dependency in FEM) and imprecision of ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
