The Role of Certifications in Improving Household Food Security Among Peruvian Farmers

open access: yesAgribusiness, EarlyView.
ABSTRACT Achieving global food security requires sustainable transformations in agri‐food systems. Voluntary Sustainability Standards (VSS) such as Organic and Fairtrade aim to internalize certain social and environmental costs while promoting more equitable value distribution, improved market access, and sustainable production practices.

Neural network‐based offset‐free model predictive control for nonlinear systems

open access: yesAIChE Journal, EarlyView.
Abstract This paper proposes an offset‐free model predictive control (MPC) framework for nonlinear systems modeled using neural network‐based nonlinear autoregressive models with exogenous inputs (NARX). To address plant‐model mismatch and ensure offset‐free tracking, the NARX model is augmented with an integrating disturbance model, resulting in an ...

On a New Hilbert-Hardy-Type Integral Operator and Applications

open access: yesJournal of Inequalities and Applications, 2010
By applying the way of weight functions and a Hardy's integral inequality, a Hilbert-Hardy-type integral operator is defined, and the norm of operator is obtained.

Refinements of Generalized Aczél's Inequality and Bellman's Inequality and Their Applications

open access: yesJournal of Applied Mathematics, 2013
We give some refinements of generalized Aczél's inequality and Bellman's inequality proposed by Tian. As applications, some refinements of integral type of generalized Aczél's inequality and Bellman's inequality are given.

Enhancing Microrobot Swarm Stability and Adaptation by Autonomous Field‐of‐View Planning

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents an adaptive cross‐field‐of‐view navigation strategy for microrobot swarms in large‐scale workspaces by integrating global path planning via A* and local replanning using optimized informed rapidly‐exploring random tree star . The hybrid approach ensures efficient and robust trajectory execution in dynamic environments, enhancing the ...

Topology Optimization of Exo‐Glove Poly II for Enhancing Functionality and Wearability

open access: yesAdvanced Intelligent Systems, EarlyView.
This study proposes a topology optimization method for Exo‐Glove Poly II to enhance functionality and wearability. By modeling its finger body as a longitudinally periodic structure, a unit cell‐level optimization—aimed at minimizing distortion and achieving user‐preferred stretchability—is established. Experimental validation shows reduced distortion,

Square function inequality for oscillatory integral operators satisfying homogeneous Carleson-Sj\"olin type conditions

open access: yes, 2019
In this paper, we establish an improved variable coefficient version of square function inequality, by which the local smoothing estimate $L^p_\alpha\rightarrow L^p$ for the Fourier integral operators satisfying cinematic curvature condition is further ...
