Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

How can children and young people have a voice in urban treescapes?

People and Nature, EarlyView.
Abstract Scientific understanding of climate change has, to date, failed to result in sufficient action. This paper proposes that a deficit model of top‐down learning and dissemination in relation to public engagement with science may be part of the problem, particularly when considering the attitudes, values and empowerment of children and young ...

Meta‐Virtuality: Strategies of Disembeddedness in Virtual Interiorities

Journal of Interior Design, EarlyView., 2022
ABSTRACT To reclaim their seat in the rapidly growing market of virtual space, designers of the built environment can benefit from reevaluating theories that see the virtual as a mere extension/reflection of the physical. By claiming ontological autonomy from external worlds, the virtual is liberated from the hegemonic control of the physical.

Dual-Polarization Radar Deception Jamming Method Based on Joint Fast-Slow-Time Polarization Modulation

Remote Sensing
To address the vulnerability of single-polarization deception jamming and simply modulated dual-polarization jamming to discrimination by dual-polarization radars, this paper proposes a deception jamming method based on joint fast–slow-time polarization ...

Theory and Design of Blink Jamming

Applied Sciences, 2020
Establishing an error in the angle estimates of a monopulse radar is critical to creating miss distance during the terminal stage of missile engagements. However, the tools for creating angle deception are limited, with blink jamming offering significant

Neural‐Network‐Based Event‐Triggered Consensus Tracking for Nonlinear Heterogeneous Multi‐Agent Systems Against Denial‐of‐Service Attacks

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This article proposes a distributed resilient control framework to ensure consensus tracking for nonlinear heterogeneous multi‐agent systems (NHMAS) under aperiodic denial‐of‐service (DoS) attacks. First, a resilient observer is introduced to estimate the leader's state considering that not all agents have direct access to the leader's ...

A review of empirical dam breach models

River, EarlyView.
Abstract Dam breach modelling is central to flood risk assessment, yet the empirical models commonly used for estimating breach parameters display considerable variability and uncertainty. This review evaluates the performance of widely applied empirical dam breach models and identifies those that consistently show lower uncertainty, such as the ...

And then there was us Et puis nous sommes apparus

Journal of the Royal Anthropological Institute, EarlyView.
In 1987, the academic conference ‘Origins and Dispersals of Modern Humans: Behavioural and Biological Perspectives’ was held in Cambridge, UK. Subsequently referred to as the ‘Human Revolution’ conference, this meeting brought together the most prominent academics working in the field of human origins, including archaeologists and palaeoanthropologists,

Torture and scepticism in Papua New Guinea witch hunts Torture et scepticisme dans les chasses aux sorcières en Papouasie‐Nouvelle‐Guinée

Journal of the Royal Anthropological Institute, EarlyView.
For over a century, anthropologists have documented the many institutions that exist to respond to witchcraft and the uncanny that it names: oracles that attempt to produce certainty by naming the witch; moots in which grievances are aired; trials in magistrates’ courts that attempt to satisfy the community while preserving the life of the accused ...

Cutting freedom down to size Liberté calibrée

Journal of the Royal Anthropological Institute, EarlyView.
Freedom, as a concept and a value, presents limited prospects for anthropological comparison. The study of enslavement, much neglected in attempts to develop an anthropology of freedom, shows that freedom has been imagined by the enslaved as the opposite of their condition only under particular circumstances.
