Robust Estimation of Motion Parameters and Scene Geometry : Minimal Solvers and Convexification of Regularisers for Low-Rank Approximation

In the dawning age of autonomous driving, accurate and robust tracking of vehicles is a quintessential part. This is inextricably linked with the problem of Simultaneous Localisation and Mapping (SLAM), in which one tries to determine the position of a vehicle relative to its surroundings without prior knowledge of them. The more you know about the object you wish to track—through sensors or mecha

Para sport translation of the IOC consensus on recording and reporting of data for injury and illness in sport

In 2020, the IOC proposed a universal methodology for the recording and reporting of data for injury and illness in sport. Para sport is played by individuals with impairment, and they have a unique set of considerations not captured by these recommendations. Therefore, the aim of this addendum to IOC consensus statement was to guide the Para sport researcher through the complexities and nuances t

Excitations in the Ultimate Quantum Fluid

Researchers have measured superfluid helium’s full dispersion spectrum, explaining discrepancies in previous studies and constraining theories of superfluidity.

Magnetic microphase inhomogeneity as a thermodynamic precursor of ground-state phase separation in weakly coupled spin-3/2 chains

γ-CoV2O6 is a quasi-one-dimensional spin-3/2 magnet that possesses two distinct magnetic orders at low temperatures with propagation vectors k1=(½,0,0) and k2=(¼ + δh, δk, - ¼ + δl), respectively. Here we use muon spin relaxation and rotation to reveal the thermodynamics of the magnetic phase separation in this compound. In the paramagnetic (PM) region, short-range correlated spin clusters emerge

A snapshot review—Fluctuations in quantum materials: from skyrmions to superconductivity

By measuring a linear response function directly, such as the dynamic susceptibility, one can understand fundamental material properties. However, a fresh perspective can be offered by studying fluctuations. This can be related back to the dynamic susceptibility through the fluctuation–dissipation theorem, which relates the fluctuations in a system to its response, an alternate route to access the

Women as agents of change? : Reflections on Women in climate adaptation and mitigation in the Global North and South

This chapter argues that most efforts aimed at using women’s positions relative to climate change will be insufficient if not conducted with great care and analytical sensitivity. It shows that mitigation and adaptation measures of climate change often target women, either as untapped resources for combating climate change or as active and powerful participants in adaptation or mitigation efforts.

Trajectories of spatial violence in Southeast Asian cities

This paper aims to reveal how urban ‘development-induced displacement’ (Koenig, 2015; Neef and Singer, 2015) shapes and perpetuates modalities of spatial violence in the context of rapidly urbanising Southeast Asia. While Southeast Asian postcolonial scholars have explored some manifestations of spatial violence such as displacement, a comprehensive regional analysis is still lacking, especially i

Troubling partnerships: Perspectives from the receiving end of capacity development

The purpose of this paper is to complement the overwhelming focus on external partners in existing studies of capacity development for disaster risk reduction (DRR) or climate change adaptation (CCA), by exploring the perspectives of internal partners on challenges and possible solutions. 27 qualitative semi-structured interviews with experts, program officers and managers in five countries in the

Effects of leg fatigue due to exhaustive stair climbing on gait biomechanics while walking up a 10˚ incline – implications for evacuation and work safety

This biomechanics study explored stride length (SL), duration (SDN), and gait ground reaction forces (GRFspeak), required coefficient of friction (RCOFpeak), joint angle (anglepeak, anglemin), angular velocities (angvelx peak), angular accelerations (angaccx peak), muscle electromyography (EMG) during the dominant leg stance phase (SP) following an exhaustive stair ascent for evacuation. Data were

Update of clothing database for existing and new Western clothing ensembles, including effects of posture, body and air movement : Report on manikin measurements for ASHRAE 1760-TRP.

ASHRAE Research Project RP-1760 aimed to update thedatabase of western clothing as used in ANSI/ASHRAE Stan-dard 55-2013, Thermal Environmental Conditions for HumanOccupancy (ASHRAE 2013a), ISO Standard 7730-2005,Ergonomics of the Thermal Environment—Analytical Deter-mination and Interpretation of Thermal Comfort Using Calcu-lation of the PMV and PPD Indices and Local ThermalComfort Criteria (ISO

Stochastic modelling of 3D fiber structures imaged with X-ray microtomography

Many products incorporate into their design fibrous material with particular levels of permeability as a way to control the retention and flow of liquid. The production and experimental testing of these materials can be expensive and time consuming, particularly if it needs to be optimised to a desired level of absorbency. We consider a parametric virtual fiber model as a replacement for the real
