Long-distance electric vehicle (EV) travel depends critically on charging infrastructure reliability. When stations fail or queues form unexpectedly, drivers face increased range anxiety and risk of getting stranded. In this demonstration paper, we present EVMapSim, a discrete-event simulator for modelling EV navigation and charging behaviour at a national scale. We demonstrate 10,000+ vehicles t…

Amid recent movements toward greater inclusivity, diversity, and authenticity in fashion, the lingerie industry faces unique challenges and opportunities in reshaping its perceived (mis)representation of gender and sexuality. A multifaceted and interdisciplinary theoretical framework is used to analyse the role of major lingerie brands - Victoria’s Secret, Aerie, and Savage X Fenty - and their ac…

The current state of art lacks a methodical, rigorous and scalable single approach to analysis of safety and security requirements.We present SHARCS (Systematic Hierarchical Analysis of Requirements for Critical Systems), addressing this gap by adopting an abstraction-based incremental approach to hazard analysis.SHARCS combines STPA-style control action analysis with Event-B formal modeling and …

Migration is often framed as a strategy for families to overcome economic hardship, yet it simultaneously generates its own adversities – most notably prolonged parent-child separation with profound effects on left-behind children’s well-being and schooling. This duality demands resilience not only from adults but also from left-behind children in transnational families. Recent scholarship increa…

This article evaluates the evidence for sentience - the capacity to have feelings - in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal’s nervous system might support sentience and whether their behaviour indicates sentience. There is very strong evidence of sentience in octopuses, which satisfy seven of the eig…

Submarine canyons are the primary conduits for particulate transport from the continents to the deep sea, including sediments, organic carbon, and pollutants. Previously, focus has primarily been on transport due to downslope gravity currents. There is increasing recognition of the role internal tides may play, however, a lack of long-term seabed monitoring limits understanding of their significa…

Context: IGR J17511−3057 is an accreting millisecond X-ray pulsar and a known type-I burster. The source was observed in outburst for the first time in 2009 and again in 2015, followed by a decade-long quiescence phase. Aims. The source was observed in a new outburst phase starting in February 2025 and lasting at least nine days. We investigated the spectral and temporal properties of IGR J17511−…

In recent years several formulations of debris indices have been proposed to provide a fast assessment of the criticality of a space object in terms of its impact on the debris environment. In a previous work, we proposed a formulation (ECOB, Environmental Consequences of Orbital Breakups) based on the evaluation of the consequences of the fragmentation of the studied object in terms of the incre…

In the framework of space debris remediation and mitigation and eco-design of space systems, a design indicator is proposed to measure the management of<br/>end-of-life options and to compare different design options of a space mission from the perspective of the impacts of space debris. Such an indicator measures the orbital space occupied by missions, seen as a resource used, the risk ind…

Several strategies have been implemented or proposed to tackle the space debris problem. However, there is still debate on the feasibility, cost and effectiveness of these mitigation measures, especially in light of the increasing use of small satellites in low Earth orbit (LEO) and the drive towards space debris remediation.<br/>This work presents a statistical source-sink debris evolution…

In recent years, the launch traffic to low Earth orbits (LEO) has undergone a significant change: while in the beginning of this century the launch rates dropped to their lowest level since the beginning of the space age, the yearly number of launches performed has now recovered to 20th century levels. Although absolute launch numbers are now comparable to historic levels, fundamental space activ…

The main focus of this work is to highlight the main parameters driving the future evolution of the debris environment, in presence of the planned LEO mega constellation of satellites. First, in order to identify the most important parameters that are actually driving the evolution of the environment and in an effort to discriminate between possibly equivalent scenarios, we applied tools from the…

The primary purpose of a hinged wing tip on an airliner aircraft is to allow an aerodynamically efficient high aspect ratio wing to enter an airport gate of standard dimensions. There exists a potential opportunity to allow a wing tip to move in flight to alleviate the loads and achieve a lower wing weight. This paper will provide a summary of the latest studies investigating the Aeroelastic beha…

In a period where the evolution of the space environment is causing increasing concerns for the future of space exploitation and sustainability, the design for demise philosophy has gained an increased interest. However, satellites designed for demise still have to survive the space environment polluted by space debris. Within this context we are developing a model to evaluate the effect of preli…

Earth orbits are becoming increasingly congested. This will not only impact future space operations but also become a concern for the population on the ground; with more spacecraft being flown, more objects will re-enter the atmosphere in an uncontrolled fashion. Parts of these satellites can reach Earth surface and endanger the ground population (e.g. ROSAT or UARS satellites). A student-run pro…

This paper presents the design and implementation details of a complete unmanned aerial system (UAS) based on commercial-off-the-shelf (COTS) components, focusing on safety, security, search and rescue scenarios in GPS-denied environments. In particular, The aerial platform is capable of semi-autonomously navigating through extremely low-light, GPS-denied indoor environments based on onboard sens…

The “year abroad” is a longstanding component of British university degree programmes in languages. As noted by other commentators (Coleman, 1997 and this volume; Collentine, 2009), the British “year abroad” is typically undertaken by language majors with several years’ prior language study and a relatively advanced proficiency level in their target language(s). It is a common requirement for pro…

The manifold of Symmetric Positive Definite (SPD) matrices has been successfully used for data representation in image set classification. By endowing the SPD manifold with Log-Euclidean Metric, existing methods typically work on vector-forms of SPD matrix logarithms. This however not only inevitably distorts the geometrical structure of the space of SPD matrix logarithms but also brings low effi…

A next generation high performance xenon resistojet delivering specific impulse above 90s would be of significant benefit to both small and newer all-electric spacecraft. Such performance would require a xenon propellant temperature of > 3000 K for gas dynamic expansion. Operation at such extreme temperatures and power densities requires a detailed understanding of numerous physical processes …
