Survey and Sequence Strategies for Full‐3D Electrical Resistivity Tomography in Archaeological Sites: A Case Study on a Domus of the Roman Town of Augusta Bagiennorum (NW Italy)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Preliminary geophysical investigations are a cost‐effective and efficient way to screen archaeological sites and locate buried structures. Ground‐penetrating radar (GPR) is one of the most widely used methods for archaeological prospection, but in some sites, it cannot be employed effectively due to the presence of clay or other electrically ...

Living IoT: A Flying Wireless Platform on Live Insects

open access: yes, 2018
Sensor networks with devices capable of moving could enable applications ranging from precision irrigation to environmental sensing. Using mechanical drones to move sensors, however, severely limits operation time since flight time is limited by the ...

The spread of non‐native species

open access: yesBiological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Random forest regression for catalyst performance prediction and validation of tri‐reforming of methane (TRM)

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Carbon dioxide‐reduced hydrogen can be synthesized through various methods such as dry‐reforming (DRM), steam reforming (SMR), and partial oxidation (POX). Tri‐reforming of methane (TRM) is a promising technology which combines all the above‐mentioned processes for the simultaneous production of hydrogen and syngas with high energy efficiency.

Optimisation of practically constrained waveforms for Rician target detection with multiple‐input‐multiple‐output radar

open access: yesIET Radar, Sonar & Navigation, 2022
In this paper, the waveform design for Rician target detection with multiple‐input‐multiple‐output radar is addressed. The relative entropy between the distributions of the observations under two hypotheses is employed as the design metric.

Digital constant‐envelope modulation scheme for radar using multicarrier OFDM signals

open access: yesIET Signal Processing, 2017
Multicarrier signals using orthogonal frequency division multiplexing (OFDM) bring many advantages to radar such as low probability of intercept, improved target detection performance, optimisation of both radar transmitter and receiver etc. A major drawback of multicarrier OFDM signals is their high peak‐to‐mean envelope power ratio, which reduces the

Strain‐based modeling and analysis for rock blasting and geomechanics applications

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper introduces a novel strain‐based modeling approach for blasting and geomechanical applications, using measurable variables like particle velocity, strain, and displacement. By bypassing complex constitutive relations, strain‐based models capture critical blasting trends and full‐blast design parameters with minimal calibration.

Constant envelope OFDM RadCom fusion system

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
A joint radar and wireless communication (RadCom) fusion system is an important trend for future intelligent transportation, such as the Internet of Vehicles (IOV). However, traditional joint orthogonal frequency division multiplexing (OFDM)-based RadCom
