A Survey of Methods for Constructing 3D Urban Models From Point Clouds

Computer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Reconnaissance‐Scale Methods for the Identification of Groundwater Discharge to Streams

Groundwater Monitoring &Remediation, EarlyView.
Abstract Identifying groundwater discharge locations is critical for understanding and monitoring groundwater contributions to streams in terms of water quantity and quality. Streams and rivers are under increasing strain from factors, including increased urbanization, agricultural land use, groundwater extraction, and climate change, which can alter ...

Freight distribution optimization by implementing the team orienteering problem with occasional drivers

International Transactions in Operational Research, EarlyView.
Abstract This research evaluates the effectiveness of a hybrid crowdshipping system that integrates occasional drivers with traditional delivery services (OD+TD) to improve the efficiency of freight distribution. By implementing the team orienteering problem with occasional drivers model, we develop a mathematical model and an agile optimization ...

Challenges to artificial intelligence‐enabled digital technology adoption in farms: a multi‐method approach

International Transactions in Operational Research, EarlyView.
Abstract Artificial intelligence (AI)‐enabled digital technologies have the potential to transform agriculture by supporting decision‐making and automating operations. However, their limited adoptions and scholars’ atheoretical explorations constrain our understanding.

Optimizing equity and efficiency in the aerial firefighting resource allocation problem

International Transactions in Operational Research, EarlyView.
Abstract This study addresses the aerial firefighting resource allocation problem, formulated as the strategic prepositioning of a heterogeneous aerial firefighting fleet across capacity‐constrained airbases. A novel bi‐objective model is proposed that simultaneously optimizes efficiency (aggregate risk‐weighted accessibility) and equity (minimized ...

Russia's Wartime Economy: Measuring Regional Inequalities From Outer Space

Journal of Regional Science, EarlyView.
ABSTRACT We study Russia's February 2022 full‐scale invasion of Ukraine as a natural experiment to determine how sudden disruptions to international market access reshape sub‐national economic inequalities. Using remotely‐sensed nighttime lights as a proxy for economic activity, we estimate the economic effects of the war at the national and regional ...

Law and Infrastructure: Reliability, Automation Transition, and Irregularities of “U‐Space”

Regulation &Governance, EarlyView.
ABSTRACT The European Union (EU) is making regulatory efforts to allow for the safe integration of drones into civilian airspace through automated means. Commission Implementing Regulation (EU) 2021/664 concerning unmanned traffic management (a system referred to as “U‐Space”) furthers that commitment. Accordingly, drone operators must avail themselves
