Artificial Intelligence–Assisted Reduced-Order Modeling and Stability Control in Granular Couette Flow
Abstract: This study develops a reduced-order and stability-aware modeling framework for dense granular Couette flow by integrating continuum mechanics, bifurcation analysis, and data-driven stability estimation. Starting from coupled governing equations for momentum, granular temperature, and microstructural evolution, the system is nondimensionalized and reduced using a Galerkin projection consistent with shear-driven boundary conditions. This yields a low-dimensional nonlinear dynamical system that preserves the essential coupling between velocity, fluctuation energy, and structural relaxation. …

Veterinary Immunology in Zoonotic Disease Control
Abstract: Zoonotic diseases, which are transmissible between animals and humans, pose a significant threat to global public health, food security, and economic stability. Veterinary immunology plays a pivotal role in understanding host–pathogen interactions, developing preventive strategies, and mitigating the impact of these diseases. Animals serve as reservoirs for a variety of pathogens, including viruses, bacteria, and fungi, which can persist asymptomatically or cause clinical disease. Understanding the immune mechanisms in both …

Improvement of Indirect Vector Control Induction Motor Drive Performance under Low Speed Operation using Five-Level Inverter
Abstract: The dynamic performance of vector controlled induction motor drive is poor and peak motor torque decreases under low speed operation. This reduction in torque is due to the non-linearity of voltage to frequency (Hz) during low frequency operation. The non-linearity is caused by stator voltage drop which in turn requires a larger percentage of overall terminal voltage. To overcome these problems multilevel inverter fed induction motor drive is presented in …
