Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

Remote Sensing in Ecology and Conservation, Volume 12, Issue 4, Page 645-660, August 2026.
This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...

Review article: the use of remotely piloted aircraft systems (RPASs) for natural hazards monitoring and management [PDF]

Natural Hazards and Earth System Sciences, 2018
The number of scientific studies that consider possible applications of remotely piloted aircraft systems (RPASs) for the management of natural hazards effects and the identification of occurred damages strongly increased in the last decade. Nowadays,

Social network dynamics under experimental manipulations of predation risk and food abundance in wild rock hyraxes

Journal of Animal Ecology, Volume 95, Issue 8, Page 1339-1357, August 2026.
This study combines replicated experimental manipulation, social network analysis, network permutations and meta‐analysis to disentangle active from spatially‐induced changes in animal network structure in the wild. It reveals that short‐term environmental changes primarily alter space use, with limited effects on social structure.

Remotely piloted aircraft systems: the introduction of the ‘flying watchtower’

Digital War, 2023
AbstractThis commentary will contest that a lack of deep critical thinking on the nature of air power and its relationship with those it overflies, surveils, and bombs by air power practitioners can lead to a void in engagement with the public and create distrust. It will discuss how the unique characteristics of Remotely Piloted Aircraft Systems (RPAS)

RAPID: Real‐time animal pattern re‐identification on edge devices, an open‐source tool for field deployment

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2379-2394, August 2026.
Abstract Automatic re‐identification of animals has significant potential to address pressing ecological and conservation challenges through improved population monitoring, individual health assessment and detailed behavioural analyses. Although numerous computer‐vision‐based solutions have been proposed and many achieve high accuracy, most remain ...

RPAS Automatic ADS-B Based Separation Assurance and Collision Avoidance System Real-Time Simulation Results

Drones, 2020
Remotely piloted aircraft systems (RPAS) are increasingly becoming relevant actors that are flying through the airspace and will gain much more importance in the future. In order to allow for their safe integration with manned conventional traffic in non-

Determination of the Sample Size of Linear Features Used in Cartographic Quality Control Through Monte Carlo Simulation

Transactions in GIS, Volume 30, Issue 5, August 2026.
ABSTRACT In sampling‐based process, sample size is always a debated topic. To assess positional accuracy using points, there are several studies and standards that determine what sample size should be used. However, for positional control using lines, there is no knowledge of a study that indicates the sample size.

Assemblage of the vertical: commercial drones and algorithmic life [PDF]

Geographica Helvetica, 2016
This paper takes up the increasingly popular topic of drones – including unmanned aerial vehicles (UAVs), small unmanned aerial systems (sUAS), remotely piloted aircraft (RPA), and a vast panoply of commercial drones and copters – to argue that our ...

Does AI Affect the Democratic Conduct of War? Analyzing US and Israeli Military AI Deployment

Global Policy, Volume 17, Issue S2, Page S45-S56, July 2026.
ABSTRACT This study examines how the use of decision‐support military Artificial Intelligence (AI) systems can affect the democratic conduct of warfare. AI can challenge the democratic conduct of warfare by introducing systemic risks such as reduced oversight, opacity, and automation bias.
