Power transformers are fundamental components in electrical grids, requiring robust insulation to operate reliably under various abnormal conditions, including overvoltages caused by lightning or switching. As defined by existing standards, the Basic Insulation Level (BIL) or Switching Insulation Level (SIL) of a transformer validates its reliabili...

This study investigated the relationship between three practical measures for evaluating Persian grammar expression skills, MLU, PDSS, and PEGT, in preschool children with developmental language disorder (DLD) and their typically developing (TD) peers. Secondary data were obtained by re-analyzing language samples collected in previous studies. Prev...
Emotional Intelligence (EI) in teaching is associated with various educational outcomes and processes. However, it has typically been measured through self-reports and general EI assessments, lacking a specific performance test with greater ecological validity in relation to the demands of the professional educational context. This study describes ...
With the large-scale construction of urban rail transit viaducts in China, the noise problem caused by trains traversing these sections has become increasingly prominent and a key technical challenge that restricts the sustainable development of rail transit. There are two main noise sources when trains pass on rail transit viaducts, namely, wheel-...
Multiple sclerosis (MS) is a neurodegenerative disease that often leads to severe disability. Although exercise, particularly strength training, improves health outcomes in MS, no standardized, reliable tool exists for functional assessment to inform tailored exercise prescriptions and patients’ categorization. This study aimed to validate the reli...
This study presents a 2D numerical simulation method for predicting the resistance of ships navigating in pack ice. The key contribution of this study lies in the derivation of analytical closed-form solutions for calculating the flexural deformation and stress distribution in an elastic plate using Symplectic Mechanics and Hooke’s laws. These solu...
Given the increasing use of innovative force plate systems in applied sports settings and the impact that anterior cruciate ligament (ACL) injuries have on team success, the purpose of the present study was to compare the lower-body neuromuscular performance characteristics of athletes who underwent ACL reconstruction (ACLR) and their non-injured c...
Oscillating grease-lubricated slewing bearings are used in several applications. One of the most demanding and challenging is the rotor blade bearings of wind turbines. They allow the rotor blades to be turned to control the rotational speed and loads of the complete turbine. The operating conditions of blade bearings can lead to lubricant starvati...
Ratooning rice plants have a high moisture content and strong adhesion during harvesting. Traditional cleaning devices are prone to clogging when processing ratooning rice, resulting in a series of problems such as high grain loss rate and high grain impurity rate. In response to the above issues, this article adopts the CFD-DEM coupling method to ...
To solve the problem of the high loss rate of threshing devices during the mechanical harvesting of ratoon rice, we propose a method using the principle of rigid–flexible coupling in this paper to reduce losses. Through analysis of the forces and collisions on ratoon rice grains during the threshing process, it has been confirmed that changing the ...
