Switched reluctance motor design for electric vehicles based on harmonics and back EMF analysis

open access: yesThe Journal of Engineering, 2019
Permanent magnet synchronous motors are widely accepted in automotive applications. The high torque density, high rotational speed with maximum efficiency in electric vehicle applications is technically challenging for motor design.

Machine Learning‐Driven Prediction of Microplastic Aging Processes and Environmental Risk Assessment Across Multi‐Media Systems

open access: yesAdvanced Science, EarlyView.
This perspective proposes a cohesive machine learning strategy to decode microplastic aging. It advocates for Federated Learning to dismantle global data silos and introduces the TRACE framework (TRansport, Aging, Corona, Ecotoxicity). By integrating physics‐informed modeling with causal discovery, this approach bridges the laboratory‐field gap to ...

Why Didn't I Get a Payout? Understanding Farmer Choices, Index Insurance, and Basis Risk

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Index insurance, while heralded as a potential solution to alleviate poverty and food insecurity among agricultural households, has its own set of challenges, notably basis risk. Basis risk is the discrepancy between the insurance payout and losses incurred, posing a significant deterrent to the adoption of index insurance.

A prototype controller for variable reluctance motors [PDF]

open access: yesIEEE Transactions on Industrial Electronics, 1996
A three-level cascade structure is proposed for the control of a variable reluctance (VR) motor. In order to deal with the highly nonlinear behavior of VR motors, the controlling system includes two variable-structure controllers for current and velocity loops as well as an intermediate torque-sharing compensator.

Direct Flux Field Oriented Control of IPM Drives with Variable DC-Link in the Field-Weakening Region [PDF]

open access: yes, 2009
This paper presents the direct flux control of an interior permanent-magnet (IPM) motor drive in the field-weakening region. The output torque is regulated by the coordinated control of the stator flux amplitude and the current component in quadrature ...

The Cost of a Nutritious Diet in Cafeterias: Evidence From US Military Dining Facilities

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Providing nutritious meals in institutional settings with financial constraints, such as military dining facilities, is challenging. The US Department of War (DoW) and US Department of Agriculture (USDA) collaborated to modernize the Basic Daily Food Allowance (BDFA) using an optimization model that incorporates service members' consumption ...
