Taxonomy of IMT Interference on Aeronautical Systems
Radio Science, Volume 61, Issue 4, April 2026.Abstract The rapid deployment of 5G and future 6G networks has raised concerns about interference with critical aeronautical systems, particularly radio altimeters and Wireless Avionics Intra‐Communications (WAIC). This paper offers a comprehensive taxonomy of the 5G/6G signal interference mechanisms, operational impacts, and mitigation strategies in ...

Conceptual Design of an Unmanned Fixed‐Wing Aerial Vehicle Based on Alternative Energy
International Journal of Aerospace Engineering, Volume 2019, Issue 1, 2019., 2019 This paper focuses on the aerodynamics and design of an unmanned aerial vehicle (UAV) based on solar cells as a main power source. The procedure includes three phases: the conceptual design, preliminary design, and a computational fluid dynamics analysis of the vehicle. One of the main disadvantages of an electric UAV is the flight time; in this sense,

The Unexpected Actor? Civil‐Military Relations and Regulatory Agency Control in Brazil
Governance, Volume 39, Issue 1, January 2026.ABSTRACT Democratic backsliding around the world has sparked debate about its impact on public administration and governance. This article explores a growing yet less visible phenomenon threatening democracy. It examines the influence exerted by authoritarian populists over autonomous regulatory agencies through militarized patronage, that is, the ...

Analyzing Nonlinear Dynamics via Data‐Driven Dynamic Mode Decomposition‐Like Methods
Complexity, Volume 2018, Issue 1, 2018., 2018 This article presents a review on two methods based on dynamic mode decomposition and its multiple applications, focusing on higher order dynamic mode decomposition (which provides a purely temporal Fourier‐like decomposition) and spatiotemporal Koopman decomposition (which gives a spatiotemporal Fourier‐like decomposition).

Earth and Space Science, Volume 12, Issue 12, December 2025.Abstract Gridded precipitation data sets have become essential for understanding climate variability and long‐term trends; however, their accuracy and reliability strongly depend on the availability and the spatial and temporal distribution of in situ meteorological observations. Here, we evaluate the performance of four gridded precipitation products:

Offline Model Predictive Control Based on Weighted Projection over Polytopes
Journal of Applied Mathematics, Volume 2015, Issue 1, 2015., 2015 This work presents a novel offline model predictive control technique for tracking of constrained systems. The quadratic programming problem, commonly found in constrained control methods, is replaced by sequential offline set projections based on priority given to the decision variables.
