Multiple Population Genetic Algorithm‐Based Inverse Kinematics Solution for a 6‐DOF Manipulator

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Compared to traditional fixed configuration manipulators, modular manipulators occupy less space, offer greater flexibility, and demonstrate stronger adaptability to diverse environments. These characteristics make them particularly suitable for operating in unknown environments, such as disaster rescue and pipeline inspection.

Fulfilling the Promise of ‘Leaving No One Behind’: Exploring Institutional Pathways to Success

open access: yesSustainable Development, EarlyView.
ABSTRACT The 2030 Agenda's Leaving No One Behind (LNOB) principle has the potential to offer a new approach to development, but whether it is achieved largely depends on how it is institutionalised within countries. This research provides the first empirical study into the relation between institutionalisation of LNOB and its goal achievement.

Rate‐type and integral‐type sectional analysis for time‐dependent response with the fib Model Code 2020

open access: yesStructural Concrete, EarlyView.
Abstract This study examines the time‐dependent behavior of reinforced and prestressed concrete structures using integral‐ and rate‐type formulations, applying the concrete creep and steel relaxation models from the fib Model Code 2020. The stress–strain law for aging concrete is expressed by a second‐order differential equation, but a single rate‐type

Shear transfer model for ultra‐high‐performance concrete incorporating fiber bridging mechanism

open access: yesStructural Concrete, EarlyView.
Abstract Ultra‐high‐performance concrete (UHPC) exhibits exceptional mechanical properties, including high shear strength, partly attributed to the fiber bridging mechanism. However, existing shear transfer models for normal‐strength concrete have not considered the significant contribution of fibers.
