On the possibilities of using a brushless doubly-fed reluctance generator in a 2 MW wind turbine

open access: yes, 2008
The paper will put a forward a description of a realistic design for a brushless doubly-fed machine that is of practical value. It takes the form a 4-pole / 8-pole machine aimed for use in a 2 MW wind turbine over a correct speed and torque range ...

U.S. Consumer Preferences for Cage‐Free Eggs and Hen Housing Policies

open access: yesAgribusiness, EarlyView.
ABSTRACT Farm animal welfare (FAW) continues to be a divisive issue in the egg industry. In the United States, 10 states and most major retailers have implemented policies or voluntary pledges to transition to 100% cage‐free egg sales. We use best‐worst scaling and discrete choice experiments to evaluate U.S.

Analytical Calculation and Verification of Radial Electromagnetic Force Under Multi-Type Air Gap Eccentricity of Hub Motor

open access: yesWorld Electric Vehicle Journal
This paper presents a method for calculating radial forces in switched reluctance motors (SRMs) under radial and tilted air gap eccentricity states. Firstly, the Fourier series method is used to establish a nonlinear model of a switched reluctance motor,

Determinants of Knowledge and Usage of Generative Artificial Intelligence in Agricultural Extension: Evidence From Tennessee Extension Personnel

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper examines the determinants of generative AI (GenAI) knowledge and usage among agricultural extension professionals. Drawing on survey data from agricultural extension personnel in Tennessee, we employ regression analyses and latent Dirichlet allocation (LDA) for topic modeling of open‐ended responses to study the knowledge and usage ...

Swedish Consumers' Willingness‐to‐Pay for Plant‐Based Proteins in Pasta Sauce: Preferences and Policy Scenarios

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper explores Swedish consumers' protein preferences by estimating the willingness‐to‐pay (WTP) for minced meat and plant‐based proteins in pasta sauce from an in‐store experiment (n = 206) and an online discrete choice experiment (n = 517). On average, the WTP was highest for minced meat.

AC/DC current ratio in a current superimposition variable flux reluctance machine

open access: yesOpen Physics, 2018
We have proposed a current superimposition variable flux reluctance machine for traction motors. The torque-speed characteristics of this machine can be controlled by increasing or decreasing the DC current.

A Medical Centrifuge System Based on the Switched Reluctance Motor

open access: yesGazi Üniversitesi Fen Bilimleri Dergisi, 2018
A prototype medical centrifuge system based on switched reluctance motors (SRMs) is designed and realized in this study. Although medical centrifuge systems use asynchronous motors or motor structures with permanent magnets in general, an SRM had many ...

Consumers' Willingness to Pay a Premium for Climate‐Friendly Food Production: The Role of Production Method Information and Social Norms

open access: yesAgribusiness, EarlyView.
ABSTRACT This study examines whether information about production methods and social norms can increase consumers' willingness to pay (WTP) a price premium for food produced using climate‐friendly farming methods. A randomized survey experiment was conducted with 1568 respondents across Denmark, Lithuania, and Spain, who were assigned to one of four ...
