‘Prototype warfare’: Innovation, optimisation, and the experimental way of warfare

open access: yesEuropean Journal of International Security, 2022
In recent years, the concept of ‘prototype warfare’ has been adopted by Western militaries to accelerate the experimental development, acquisition, and deployment of emerging technologies in warfare. Building on scholarship at the intersection of Science

Optimal Configuration Planning for Sensor Network Serviceability Under a System Coverage Constraint

open access: yesIEEE Access, 2021
We develop an optimization approach for the planning problem of configuring the positions of sensors within a sensor network for minimization of the travel length required to service the sensor locations.

Review of Military Casualties in Modern Conflicts—The Re-emergence of Casualties From Armored Warfare

open access: yesMilitary Medicine, 2021
Introduction The re-emergence of armored warfare in modern conflicts has resulted in a higher number of extremity injuries, burns, and brain injuries. Despite this dramatic increase, little is reported on the type of injuries caused and their management.

Narrow band space scanning two-dimensional linear frequency diverse array radar

open access: yesThe Journal of Engineering, 2019
Two–dimensional (2D) linear frequency diverse array (FDA) concept is extended to scan a 2D wide angular sector. This is achieved by highly unequal frequency increments in orthogonal 2D directions of the array.
