Distributed Task Allocation and Trajectory Planning for Heterogeneous UAV Swarms in Multi-Constraint Environments

open access: yesAerospace
Owing to the stringent spatio-temporal coupling and kinematic constraints, the task allocation problem for heterogeneous unmanned aerial vehicle (UAV) swarms is generally regarded as an NP-hard problem.

Optimization Techniques for Verification of Out-of-Order Execution Machines

open access: yesJournal of Electrical and Computer Engineering, 2010
We develop two optimization techniques, flush-machine and collapsed flushing, to improve the efficiency of automatic refinement-abased verification of out-of-order (ooo) processor models.

ADAPT: An Autonomous Forklift for Construction Site Operation

open access: yesJournal 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.

Vehicle scheduling optimization at unsignalized intersection based on Petri net and improved black-winged kite algorithm

open access: yesNantong Daxue xuebao. Ziran kexue ban
To meet the demand for efficient vehicle passage at unsignalized intersections in intelligent connected environments, this study proposes a new vehicle scheduling optimization method for unsignalized intersections based on a Petri net model, a deadlock ...

Static Deadlock Detection for Rust Programs [PDF]

open access: yes
Rust relies on its unique ownership mechanism to ensure thread and memory safety. However, numerous potential security vulnerabilities persist in practical applications. New language features in Rust pose new challenges for vulnerability detection.

Distributed Deadlock Detection in Ada Runtime Environments

open access: yes, 1990
Distributed deadlock detection has been studied in distributed database systems and distributed timesharing operating systems, but has not been widely used in real-time systems such as Ada runtime environments.

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

open access: yesSmall, 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,

A livelock control policy for a flexible manufacturing system modeling with a subclass of generalized Petri nets

open access: yesCogent Engineering, 2014
Livelocks, like deadlocks, can result in the serious problems in running process of flexible manufacturing systems (FMSs) as well. Current deadlock control policies based on the approaches of siphon detection and control, cannot cope with livelocks in a ...

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

open access: yesSmall, 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

open access: yesSystems 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.
