High-Fidelity Dynamic Digital Twin Modeling Method For Permanent Magnet Synchronous Motor, He Lai, Jinquan Yang, Cong Peng, Bei Li

Journal of System Simulation

Abstract: Conventional mechanism models often suffer from model mismatch due to the absence of nonlinear mechanical damping representation and the dynamic drift of electromagnetic parameters. To address this issue, a high-fidelity dynamic digital twin modeling method for permanent magnet synchronous motors is proposed. In the static mechanism modeling dimension, a friction energy decoupling strategy is proposed, which fundamentally overcomes the inherent conflict between steady-state accuracy and transient response from a physical logic perspective. For dynamic model updating, a distributed cascaded sensing architecture based on the multi-innovation recursive least squares and extended Kalman filter (MIRLS-MIEKF) algorithms is proposed. This architecture enables …

Literacy Activities To Prepare Mll Students For An Art Museum Visit, Marion J. Tate

Michigan Reading Journal

This article describes how I prepared newcomer Yemeni students to visit, understand, and learn from museums while also strengthening their English language development and cultural identity. Many students had limited English proficiency; however, they brought rich personal, family, and cultural knowledge into the classroom. To build on those strengths, I used literacy-based activities before, during, and after museum visits. These activities included shared and independent reading with e-books, pre-assessment charts, vocabulary development, guided discussions, reflective writing, collage-making, and student-led decision-making. Each strategy helped students practice English in meaningful ways while connecting museum content to memory, immigration, history, culture, and identity. …

The Anatomy And Physiology Of Signed Language Articulation, Leah C. Geer

Society for American Sign Language Journal

Speech-language pathologists (SLPs) receive extensive training in the anatomy and physiology of the oral speech and swallowing mechanisms. However, SLPs who serve individuals using a signed language like American Sign Language (ASL) may struggle to apply their training to appropriately assess and treat signed language productions in such students. Similarly, signed language specialists often lack foundational clinical knowledge to work effectively in the context of signed production. This article provides a detailed anatomical exploration of the primary sign language articulators, highlighting parallels between oral and manual articulators. SLPs learn in graduate school which speech sounds typically emerge at what ages …

Stuttering-Like Behaviors In Asl: Clinical Position Paper On Assessment Considerations And Recommendations, Jody Cripps, Mark W. Pellowski
