Feasibility Analysis of Permanent Magnet Traction Technology on Nanjing Metro Line 9 Trains
Chengshi guidao jiaotong yanjiu[Objective] Under the same power configuration, the cost of a permanent magnet synchronous traction system is higher than that of an asynchronous traction system. However, the former can effectively reduce the operational consumption of trains. Therefore,

The transfer function of a traction asynchronous motor controlled by a four-square converter
IOP Conference Series: Materials Science and Engineering, 2020 Abstract An expression for the transfer function of a traction asynchronous motor with a four-square converter is derived. It is shown that the basic properties of the traction motor, which are a four-square converter, correspond to the linearization coefficients.

AI Magazine, Volume 47, Issue 2, Summer 2026.Abstract The exponential growth of scientific literature—over 2.5 million papers and 3.5 million patents annually—poses critical challenges for knowledge discovery. To address these, we propose SCIMKG (Scientific Knowledge Graph), a framework for constructing scientific knowledge graphs via multi‐source heterogeneous multi‐source.

Measuring Cognitive Load Index in Online Learning: A Multi‐Modal Approach
Journal of Computer Assisted Learning, Volume 42, Issue 3, June 2026.ABSTRACT Background Online learning has become increasingly prominent in education, necessitating a deeper understanding of its impact on students' cognitive load (CL). Existing studies often focus on single data sources and overlook multimodal assessments, limiting a deeper understanding of how CL and emotional states manifest and interact during ...

‘Unbecoming’ a Professional: The Role of Memory during Field Transitions in Japan and the USA
Journal of Management Studies, Volume 63, Issue 4, Page 1837-1873, June 2026.Abstract Existing scholarship documents how, in becoming a professional, such as a partner in a professional services firm (PSF), one's habitus comes into alignment with field expectations. Less understood, however, is what happens to habitus and, relatedly, to professionals' accumulated cultural, social, and economic capitals, as individuals ‘unbecome’
