(author), Lloyd, David G. (author), Carty, Christopher P. (author)Background: Most cases of toe walking in children are idiopathic. We used pathology-specific neuromusculoskeletal predictive simulations to identify potential underlying neural and muscular mechanisms contributing to idiopathic toe walking. Methods: A musculotendon contracture was added to the ankle plantarflexors of a generic musculoskeletal...journal article 2024

Chandrasegaran, R.S.K. (author), Salah, Almila Akdag (author), Lloyd, P.A. (author)Analysing transcripts of design activity typically involve either close reading or manual coding of data, which limits the amount of data that can be analysed. In contrast, we explore a machine-learning based linguistic analysis tool called Empath to identify patterns of reasoning in design talk. The data we use derives from the Design...journal article 2023

(author), van der Krogt, Marjolein M. (author)Spasticity is a common impairment within pediatric neuromusculoskeletal disorders. How spasticity contributes to gait deviations is important for treatment selection. Our aim was to evaluate the pathophysiological mechanisms underlying gait deviations seen in children with spasticity, using predictive simulations. A cluster analysis was...journal article 2023

Bravo, Úrsula (author), Cortés, Catalina (author), Lloyd, P.A. (author), Jones, Derek (author)Educational systems face increasingly complex demands, confronting teachers with multidimensional people-centred problems rarely solved by linear or standardised solutions. Nevertheless, teachers must juggle multiple variables simultaneously in their daily work. This can lead to routine and unreflective decisions that do not consider unique...journal article 2023

Ivins, E. R. (author), van der Wal, W. (author), Wiens, D. A. (author), Lloyd, A. J. (author), Caron, L. (author)The Antarctic mantle and lithosphere are known to have large lateral contrasts in seismic velocity and tectonic history. These contrasts suggest differences in the response timescale of mantle flow across the continent, similar to those documented between the northeastern and southwestern upper mantle of North America. Glacial isostatic...journal article 2023

van der Burg, Vera (author), de Boer, Gijs (author), Akdag Salah, Amila (author), Chandrasegaran, R.S.K. (author), Lloyd, P.A. (author)Artificial intelligence (AI) is increasingly being viewed as a creative partner rather than as a tool. How to design such collaborations is still a subject of speculation. In this pictorial, we propose a collaborative role for AI to prompt self-reflection. We explore this through a practice-based inquiry of whether and how AI could help a...conference paper 2023

Klapwijk, M.D. (author), Lloyd, Thomas (author), Vaz, Guilherme (author)A new partially averaged Navier-Stokes (PANS) closure is derived based on the k-kL (KSKL) model. The aim of this new model is to incorporate the desirable features of the KSKL model, compared to the k-ω shear stress transport model, into the PANS framework. These features include reduced eddy-viscosity levels, a lower dependency on the cell...journal article 2022

Mello Pereira Uriartt, S. (author), Celik, S (author), Lloyd, P.A. (author)In the midst of climate change, and the need to seek more sustainable ways of living, design is increasingly tackling problems at a societal level. This paper reflects on a strategic design project at a Brazilian foundation focused on sustainable development in the Amazon rainforest region. In this study, we asked what contributions design can...conference paper 2022

Lloyd, P.A. (author), Chandrasegaran, R.S.K. (author), Akdag Salah, A.A. (author)Design thinking concepts such as storytelling, framing, and co-evolution, have been established from close readings of design activity. The increase in easy-to-use computational methodologies provides an opportunity to validate these concepts more widely. Among these concepts, storytelling is already operationalised through various computational...conference paper 2022

Chandrasegaran, R.S.K. (author), Akdag Salah, A.A. (author), Lloyd, P.A. (author)Abstract. Analysing records of design activity such as transcripts or documents have typically involved close reading of transcripts and manual identification of concepts and behaviours. We explore the applicability of a machine-learning based computational tool—called Empath—in identifying high-level patterns in design talk. Specifically, we...conference paper 2022

Kim, A. (author), van der Bijl-Brouwer, M. (author), Mulder, I. (author), Lloyd, P.A. (author)In recent years, governments have increasingly pursued innovation by embed-ding design into their organizations. One particularly common approach to em-bedding design in government organization is to establish public sector innova-tion labs. These labs are described as contributors and facilitators of innovation in policymaking processes;...conference paper 2022

Lidtke, Artur K. (author), Klapwijk, M.D. (author), Lloyd, Thomas (author)Inflow turbulence is relevant for many engineering applications relating to noise generation, including aircraft wings, landing gears, and non-cavitating marine propellers. While modelling of this phenomenon is well-established for higher Mach number aerospace problems, lower Mach number applications, which include marine propellers, still...journal article 2021

(author)Accurate predictive simulations of human gait rely on optimisation criteria to solve the system's redundancy. Defining such criteria is challenging, as the objectives driving the optimization of human gait are unclear. This study evaluated how minimising various physiologically-based criteria (i.e., cost of transport, muscle activity, head...journal article 2021
