A Review of Modeling and Control Techniques for Unmanned Aerial Vehicles

open access: yesEngineering Reports, Volume 7, Issue 6, June 2025.
By systematically classifying UAV modeling techniques and comparing control methods, this paper addresses a notable gap in the current literature. Furthermore, it highlights emerging trends and challenges in UAV control systems, providing valuable insights to guide future research toward enhancing the stability, efficiency, and adaptability of ...

Proposal for a cumulant-based Bell test for mesoscopic junctions

open access: yes, 2011
The creation and detection of entanglement in solid state electronics is of fundamental importance for quantum information processing. We prove that second-order quantum correlations can be always interpreted classically and propose a general test of ...

Statistics of Transmission Eigenvalues in Two-Dimensional Quantum Cavities: Ballistic versus Stochastic Scattering

open access: yes, 2007
We investigate the statistical distribution of transmission eigenvalues in phase-coherent transport through quantum dots. In two-dimensional ab-initio simulations for both clean and disordered two-dimensional cavities, we find markedly different quantum ...

Comparison between ray-tracing simulations and bi-directional transmission measurements on prismatic glazing [PDF]

open access: yes, 2005
Evaluation of solar heat gain and daylight distribution through complex window and shading systems requires the determination of the bi-directional transmission distribution function (BTDF). Measurement of BTDF can be time-consuming, and inaccuracies are

Towards a global understanding of tree mortality

open access: yesNew Phytologist, Volume 245, Issue 6, Page 2377-2392, March 2025.
Summary Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground‐based long‐term forest monitoring with large‐scale remote sensing.

Three-vector model predictive power control of doubly fed induction generator based on linear extended state observer under unbalanced grid

open access: yesInternational Journal of Electrical Power & Energy Systems
Doubly-fed induction generator (DFIG) is susceptible to unbalanced grid voltage and mismatched motor parameters during grid-connected operation. The conventional model predictive control (MPC) has low complexity and fast dynamic response, which is widely
