An experimental investigation of wind turbine wakes using Particle Image Velocimetry

, 1993
Determination of the aerodynamic performance of horizontal-axis wind turbines (HAWT) is complicated by problems such as wake deformation effects and free stream turbulence.

Understanding Egg Price Volatility and Policy Implications in the U.S. With Machine Learning

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Eggs are an inexpensive and sustainable source of proteins, but volatility in the U.S. egg prices has intensified in recent years, raising concerns over food affordability and market stability. This study examines the drivers of U.S. egg price dynamics over 2004–2025 using a two‐stage framework that combines LASSO‐based variable selection with

Application of particle image velocimetry to wind turbine wakes

, 1993
Wind turbine performance is critically dependent on the geometry of the rotor wake. Acquisition of detailed wake data is of major importance for further development of wind turbine studies.

Chinese Trade Competition and Rural Mexican Migration

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT China's accession to the World Trade Organization in 2001 reshaped global trade, reducing U.S. demand for Mexican manufactured goods and weakening Mexico's manufacturing employment. This study estimates how this trade‐induced decline affected migration and employment decisions among rural Mexicans.

Staging an Experience of Cultural Heritage Preservation: Consumers' Willingness to Pay for Heirloom Rice in the Philippines

Agribusiness, EarlyView.
ABSTRACT The Cordillera Administrative Region in the Philippines is home to terraced rice embedded in centuries of cultural heritage. However, weak market incentives threaten sustained production, jeopardizing indigenous communities' cultural heritage and the in situ biodiversity of rice genetic resources.

The effect of blade aerodynamic modelling on the prediction of the blade airloads and the acoustic signature of the HART II rotor

, 2009
As a rotorcraft descends or manoeuvres, the interactions which occur between the rotor blades and vortical structures within the rotor wake produce highly impulsive loads on the blades and with these a highly intrusive external noise.

Not All Agreements Are Equal: Heterogeneous Effects of RTAs on Latin American Agri‐Food Exports, 1990–2019

Agribusiness, EarlyView.
ABSTRACT Since the final decade of the 20th century, Latin American countries have increasingly regarded the signing of regional trade agreements (RTAs) as a promising strategy for expanding their exports. Within this context, the main objective of this study is to assess the impact of RTAs on agri‐food exports in Latin America over the period 1990 ...
