3D Cruise Trajectory Optimization Inspired by a Shortest Path Algorithm

open access: yesAerospace, 2020
Aircrafts require a large amount of fuel in order to generate enough power to perform a flight. That consumption causes the emission of polluting particles such as carbon dioxide, which is implicated in global warming.

An Improved Tight Closure Algorithm for Integer Octagonal Constraints

open access: yes, 2007
Integer octagonal constraints (a.k.a. ``Unit Two Variables Per Inequality'' or ``UTVPI integer constraints'') constitute an interesting class of constraints for the representation and solution of integer problems in the fields of constraint programming ...

Modified Floyd–Warshall’s Algorithm for Maximum Connectivity in Wireless Sensor Networks under Uncertainty

open access: yesDiscrete Dynamics in Nature and Society, 2022
The main objective of this paper is to find the duration of maximum time connectivity of sensor nodes under uncertainty utilizing the prespecified voltage/power of each sensor node. Wireless sensor networks (WSNs) are composed of nodes that transmit data between each other over routing.

Exact Methods for the Split Delivery Vehicle Routing Problem With Two‐Dimensional Loading Constraints

open access: yesNetworks, Volume 86, Issue 4, Page 361-388, December 2025.
ABSTRACT The Split Delivery Vehicle Routing Problem with Two‐dimensional Loading Constraints (2L‐SDVRP) integrates vehicle routing, split delivery, and two‐dimensional packing constraints. In the 2L‐SDVRP, customers can be served by multiple vehicles, and their demands consist of different two‐dimensional rectangular items that must be packed in the ...

Dynamic impedance model based two‐stage customized charging–navigation strategy for electric vehicles

open access: yesEnergy Conversion and Economics, 2023
With the continuously increasing penetration of electric vehicles (EVs), the mutual match between the distribution of charging resources and the spatial–temporal distribution of EV charging demands is becoming increasingly important.

Seamount larval dispersal networks: A potential strategy for conserving ecological connectivity from deep‐sea mining

open access: yesEcological Applications, Volume 35, Issue 7, October 2025.
Abstract Seamounts are unique habitats in the deep sea facing anthropogenic stressors, including future deep‐sea mining. To conserve patchy marine habitats such as seamounts, it is critical to design conservation area networks that maintain connectivity by larval dispersal. This study conducted biophysical modeling to quantify larval dispersal among 18
