An inequality for convex functionals and its application to a maxwellian gas
Le Matematiche, 1991 We study the trend towards equilibrium of the solution of the spatially homogeneous Boltzmann equation for a gas of Maxwellian molecules. The cases of axially symmetric and plane initial densities are investigated.

Impulsive Thruster Control for Spacecraft Docking: A Lyapunov Approach
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT In this work, we propose a novel discontinuous impulsive controller for nonlinear systems that admit continuous‐time stabilizing controllers. Specifically, we develop a technique for generating discrete control pulses of short duration based on the Lyapunov candidate function associated with a continuous‐time controller. Our method uses a real‐

Deadbeat Robust Model Predictive Control for Linear Parameter‐Varying Systems
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT The concept of Deadbeat Robust Model Predictive Control (DRMPC) has recently been established for linear systems, providing full system theoretic guarantees, while reducing the computational and conceptual complexity. This article extends DRMPC to systems with multiplicative uncertainty (“robust linear”) and systems that depend on a (slowly ...

The role of identification in data‐driven policy iteration: A system theoretic study
International Journal of Robust and Nonlinear Control, EarlyView.Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

Sustainable Development, EarlyView.ABSTRACT This study examines the interplay between climate change, violent conflict and forced migration in the Middle East and North Africa (MENA), focusing on asylum flows to the European Union (EU). By integrating high‐resolution climate, conflict and socioeconomic data spanning 2000 to 2023, we develop a comprehensive empirical framework to ...

Sustainable Development, EarlyView.ABSTRACT Achieving the Sustainable Development Goals (SDGs) requires transparent and accountable local governments, yet little is known about the structural drivers of municipal transparency. This study introduces a machine learning approach to predict municipal transparency using the Bidimensional Transparency Index (BTI), which measures both the ...

Global Energy Stability of a Discrete Fractional Generalized Gray–Scott Reaction-Diffusion System
Journal of MathematicsThis paper establishes a rigorous framework for the global energy-stability (ES) analysis of a discrete generalized Gray–Scott (GS) reaction-diffusion system (RDs) driven by a Caputo-like fractional difference (CLFD) operator.
