AI Revolution and Warfare: A New Paradigm Shift in Defence Procurement, Restructuring, Training, and Recruitment

Canadian Public Administration, Volume 69, Issue 2, Page 250-277, June 2026.
Abstract The war in Ukraine and Israel's successful operations have demonstrated the apparent shift in military operations, strategic defence spending, and innovations. Drawing parallels to the industrial revolution and how it slowly transferred military procurement, training, and deployment, the current study also highlights the AI revolution and the ...

Underwater Communication Using Acoustic Parametric Arrays [PDF]

The 4th International Electronic Conference on Sensors and Applications, 2017
This paper presents a study of different types of parametric signals with application to submarine acoustic telecommunications. In all of them, the carrier frequency is 200 kHz, which corresponds to that resonation of the transducer under study, while they differ by the different modulations they present. In this sense, we study modulations with sweeps

Collaborative Sampling and Imaging of Phytoplankton Communities by Two Long‐Range Autonomous Underwater Vehicles Using Acoustic Tracking and Messaging

Journal of Field Robotics, Volume 43, Issue 3, Page 1861-1870, May 2026.
ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.

Optoacoustic Neuromodulator by In Situ Photothermal Curing of Polydimethylsiloxane

Advanced Optical Materials, Volume 14, Issue 16, 24 April 2026.
Photoacoustics provides a powerful tool for generating miniaturized and patterned ultrasound field. Here, we report a novel, highly versatile method for fabricating optoacoustic emitters via an in situ photothermal curing process of PDMS. This technique enables high‐precision deposition across diverse platforms, including programmed flat substrates and
