Time-Varying Kelvin Wake Model and Microwave Velocity Observation

open access: yesSensors, 2020
In the synthetic aperture radar (SAR) imaging of ship-induced wakes, it is difficult to obtain the Doppler velocity of a Kelvin wake due to the lack of time-varying wake models and suitable radar equipment.

Feedback Linearisation with State Constraints

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 17, Page 7579-7595, 25 November 2026.
ABSTRACT Feedback Linearisation (FBL) is a widely used technique that applies feedback laws to transform input‐affine nonlinear control systems into linear control systems, allowing for the use of linear controller design methods such as pole placement.

P4FPID: A Toolbox for Direct and Advanced Interactions With Fuzzy Logic Controllers With an Application to a Ball‐and‐Beam System

open access: yesComputer Applications in Engineering Education, Volume 34, Issue 6, November 2026.
ABSTRACT Fuzzy logic control is well known for its robustness across various automation engineering applications. Its structured linguistic modeling of human expertise and empirical knowledge makes it attractive to both students and control engineers. However, such expertise can only be developed through practice and trials. Existing solutions are time‐

AMPLIAÇÃO DO CALENDÁRIO DE SEMEADURA DA SOJA NO RIO GRANDE DO SUL PELO USO DE CULTIVARES ADAPTADOS AOS DISTINTOS AMBIENTES

open access: yesPesquisa Agropecuária Gaúcha, 2000
A época de semeadura é, provavelmente, a prática cultural isoladamente mais importante para a soja [Glycine max (L.) Merrill]. A melhor época de semeadura para esta oleaginosa depende, principalmente, da temperatura do solo para a germinação e emergência,

A perspective on parsimonious hybrid models for online use: Augmenting fundamental models with ARIMA disturbances

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5854-5874, November 2026.
Abstract Hybrid models (HMs) combine fundamental model (FM) equations with empirical components. These models can lead to improved predictions because they reduce process/model mismatch and can account for phenomena that are not considered in the FM equations.

Modulation-mode and power-assignment for SVD-assisted downlink multiuser MIMO systems [PDF]

open access: yes, 2010
Multiuser multiple-input multiple-output (MIMO) downlink (DL) transmission schemes experience both multiuser interference as well as inter-antenna interference.

CLEAR Interference Cancellation in a Wideband Dual‐Channel Receiver for Independent Satellite Multi‐Connectivity Links

open access: yesInternational Journal of Satellite Communications and Networking, Volume 44, Issue 6, Page 689-699, November/December 2026.
ABSTRACT In this paper, the correlation learning estimation and adaptive reduction (CLEAR) of interference, an adaptive, blind and transparent interference compensation method applied in a wideband dual‐channel receiver, is studied for a pair of independent satellite multi‐connectivity links, using the same carrier frequency and signal bandwidth in use

Miniaturized Wideband MIMO Antenna based on Hybrid Isolation Technique

open access: yesJournal of Communications Software and Systems
A compact wideband two-port multi-input-multi-output (MIMO) antenna for 5G sub-6 communication is proposed in this research. The MIMO antenna consists of a coplanar waveguide and a Moore fractal based on the second iteration, comprising two T-stub shapes
