Prioritization of the Sustainable Development Goals: Developing and Testing a Novel Framework Under Varying Geographic Scales

open access: yesSustainable Development, EarlyView.
ABSTRACT This study develops and tests a novel prioritization framework for the Sustainable Development Goals (SDGs) under varying geographic scales (regional, sub‐regional, national), focusing on the Middle East and North Africa (MENA) region as a pilot case.

The Impact of Climate Risks on Corporate Debt Financing

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT As global resource demands and climate pressures grow, companies face the dual challenge of sustainability and environmental responsibility. Using panel data from U.S. publicly listed firms (2014–2022) and a text‐based proxy for climate risks, this study explores the impact of just transition climate risks on corporate debt financing.

Observer-Type Consensus Protocol for a Class of Fractional-Order Uncertain Multiagent Systems

open access: yesAbstract and Applied Analysis, 2012
This paper investigates the consensus problem for a class of fractional-order uncertain multiagent systems with general linear node dynamics. Firstly, an observer-type consensus protocol is proposed based on the relative observer states of neighboring ...

Automatic tuning of paper machines cross-direction controllers via linear matrix inequalities

open access: yesJournal of Electrical Systems and Information Technology, 2015
The paper machine cross-direction (CD) process is a large-scale spatially distributed system. It is known to be severely ill-conditioned as the gain rolls down to zero for some of the process directions.

How Does State Fragility Drive Environmental Degradation? A Multidimensional Analysis of Governance and Socio‐Economic Vulnerabilities

open access: yesKyklos, EarlyView.
ABSTRACT The growing crises in the environmental sector worldwide have increased the call for better comprehension of the linkage among governance, socio‐economic stability, and environmental degradation. In this respect, state fragility—a term covering governance gaps, political instability, and economic turmoil—has emerged as a vital and rather ...

The Nonfragile Controller with Covariance Constraint for Stable Motion of Quadruped Search-Rescue Robot

open access: yesAdvances in Mechanical Engineering, 2014
The problem of a stable motion for the quadruped search-rescue robots is described as a variance constrained uncertainty in the discrete systems. According to the model structure of the quadruped search-rescue robot, the kinematics of the robot is ...

Data‐Based Refinement of Parametric Uncertainty Descriptions

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 6, Page 3210-3228, April 2026.
ABSTRACT We consider dynamical systems with a linear fractional representation involving parametric uncertainties which are either constant or varying with time. Given a finite‐horizon input‐state or input‐output trajectory of such a system, we propose a numerical scheme which iteratively improves the available knowledge about the involved constant ...
