Impacts of technology on the capacity needs of the US national airspace system [PDF]

A review of the U.S. air transportation system is undertaken, focusing on airspace and airport capacity. Causes of delay and congestion are investigated. Aircraft noise is identified as the fundamental hindrance to capacity improvement.

Governing Within the Constraints of Carbon Budgets: Regional Insights From Sweden

Environmental Policy and Governance, EarlyView.
ABSTRACT Staying within the limits of a rapidly shrinking global carbon budget while avoiding dependency on negative emissions technologies and carbon dioxide removal remains a significant challenge in a multi‐level governance system, where resources and responsibilities are dispersed among different actors.

Design of a Hydroelectronic Solar‐Tracking System for Solar Panels

Energy Science &Engineering, EarlyView.
A prototype of a passive solar‐tracking system utilizing buoyant force based on water level was developed, and its MATLAB/Simulink model was implemented. This study is expected to encourage researchers to design solar‐tracking mechanisms using metals with different thermal expansion coefficients, air, oil, and other fluids. ABSTRACT This study presents

A compensatory algorithm for the slow-down effect on constant-time-separation approaches [PDF]

In seeking methods to improve airport capacity, the question arose as to whether an electronic display could provide information which would enable the pilot to be responsible for self-separation under instrument conditions to allow for the practical ...

Revisiting the Nexus Between Trade Liberalisation and Income Inequality: The Case of Sub‐Saharan African Countries

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper examines the impact of trade liberalisation on income inequality across 24 Sub‐Saharan African (SSA) countries from 2000 to 2020. Using IV‐Tobit and 2SLS models, we consistently find that greater trade openness significantly exacerbates inequality in the region. Critically, we document an inverted U‐shaped relationship between trade

Artificial intelligence for personalized multiple micronutrient supplementation in maternal health

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Maternal undernutrition and micronutrient deficiencies remain pervasive, contributing to adverse pregnancy outcomes and long‐term health risks for mothers and offspring. Multiple micronutrient supplementation (MMS) during pregnancy has demonstrated benefits, including reduced risks of low birth weight, small‐for‐gestational‐age births, and ...

THE EVALUATION OF AIRCRAFT OPERATIONS AT AIRPORTS HAVING DIFFERENT NUMBERS AND CONFIGURATIONS OF RUNWAYS

Havacılık ve Uzay Teknolojileri Dergisi, 2012
One of the important parts of the air transportation system is the airport which needs to increase its capacity due to a growth in air traffic demand. Many factors influence the capacity of an airport airside, and some are more significant than others ...

Uncovering the key bilateral trade linkages in the U.S. domestic food supply chain through disruption simulations

Journal of the Agricultural and Applied Economics Association, EarlyView.
Abstract This paper uses counterfactual simulations to examine the impact of bilateral trade linkage disruptions on the U.S. agricultural and food trade system. Using an econometric gravity model, we estimate the relationship between disruptions and trade flows, identify critical state‐to‐state trade linkages whose disruption would significantly impact
