Traffic Management of Multi-AGV Systems by Improved Dynamic Resource Reservation

IEEE Access
Automated guided vehicles (AGVs) are widely used for material handling in warehouses and automated production lines due to their high efficiency and low failure rate with respect to human operated load carriers.

Globalizing Comparative Public Administration With Integrative Contextualization: State Autonomy in the Developmental Path of Hong Kong and Singapore

Public Administration and Development, EarlyView.
ABSTRACT The lack of a common variable for comparison has been a major obstacle to the development of Comparative Public Administration (CPA). State autonomy enables an integrative contextualization approach, allowing both the analysis of contextual individual country experiences and the generation of generalized comparable knowledge.

ADAPT: An Autonomous Forklift for Construction Site Operation

Journal of Field Robotics, EarlyView.
ABSTRACT Efficient material logistics are critical in controlling costs and schedules in the construction industry. However, manual material handling remains prone to inefficiencies, delays, and safety risks. Autonomous forklifts offer a solution to streamline on‐site logistics, reducing reliance on human operators and mitigating labor shortages.

Bifunctional Electrocatalysts in Rechargeable Lithium‐Gas Batteries: Material Evolution and Mechanistic Insights from Metal‐Free Carbons to Carbon‐Supported Single‐Atom Sites

Small, EarlyView.
This review charts the material evolution of bifunctional electrocatalysts for rechargeable lithium‐gas batteries. It highlights the journey from heteroatom‐doped, metal‐free carbon architectures to precision‐engineered carbon‐supported single‐atom sites. The discussion focuses on mechanistic insights into how these catalysts govern reversible O2, CO2,

Photo‐Activated Merging Cascades in Droplet Swarms Upon Synergistic Solvation of Surfactants

Small, EarlyView.
UV activates the motility of UV‐responsive droplets through a decylammonium/carbamate crystalline layer at the air/water interface. Upon merging with immobilized C12E3 surfactant droplets in the layer, hybrid droplets form which dissolve the layer due to synergistic solvation. In large droplet fields, this non‐linear behavior drives cascading events of

From Map Follower to Navigator: Archetypes of Environmental Impact Assessment

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Environmental impact assessment (EIA) scholarship is commonly framed as a tension between efficiency and comprehensiveness paradigms. These paradigms describe a persistent tension but cannot explain how EIA operates through it. Drawing on social systems theory, this analysis traces that operation.

An integrated control method for designing non-blocking supervisors using Petri nets

Advances in Mechanical Engineering, 2017
This article presents an efficient integrated approach on designing a non-blocking supervisor for the most general classes of Petri nets, called G -systems that allow multiple resource acquisitions.

Looking for Trouble: Pre‐Intervention Monitoring in Human and AI Driver Training

Symbolic Interaction, EarlyView.
We compare two types of situations involving monitoring of car driving: a driving instructor overseeing a trainee driver and a safety driver overseeing the performance of autonomous vehicle (AV) software. Our focus is on instances of monitoring that precede (1) interventions that are aborted before impacting the driving and (2) actual interventions on ...

An algorithm to evaluate implementation cost for liveness-enforcing supervisors designed by deadlock prevention policy

Advances in Mechanical Engineering, 2016
Deadlock prevention policy is widely used to design the liveness-enforcing supervisors because of its advantage that deadlocks are considered and solved in design and planning stages for flexible manufacturing systems modeled with Petri nets.
