This work presents large-scale elasto-plastic topology optimization for design of structures with maximized energy absorption and tailored mechanical response. The implementation uses parallel computations to address multi million element three-dimensional problems. Design updates are generated using the gradient-based method of moving asymptotes and the material is modeled using small strain, non

This paper analyses the integration of social considerations into public transport planning. It addresses the challenge of balancing social benefits against objectives such as efficiency and cost minimization. Through a literature review, this paper examines methods for assessing public transport accessibility for potentially disadvantaged groups and identifies knowledge gaps in existing research.

This is the proceedings volume from the 8th biannual teaching and learning conference at Lund University, LUTL-22. The conference theme, Lifelong Learning and Higher Education: New (and Old) Perspectives, gave rise to a rich spread of presentations and discussions. The volume in your hand holds 13 contributions based on keynote addresses, papers, panels, and roundtable discussions from the confere

According to the World Health Organization Wheelchair Provision Guidelines (2023) wheelchair training is a critical component of the wheelchair provision process. In fact, the guidelines ‘strongly recommend’ that training for power and manual wheelchairs needs to be provided to enable maximum use and prevent abandonment and secondary injuries.

Background: Infants and toddlers with disabilities follows the same developmental paths as typically developing children, but build individual patterns of achievements in their own pace. Aim: To illustrate development in infants who got opportunities to experience locomotion before the age when they developed the physical abilities to move by rolling, crawling, creeping or walking. Method: Re-anal

This study is concerned with how contemporary Belfast riots are represented in digital culture, with a specific focus on how social resilience is discursively cultivated (or hindered) through memes about said political violence.While a substantial amount has already been written about everyday practices in post-conflict Belfast, less is known about how digital narratives represent and make sense o

This study investigated the variability of antioxidant compounds and capacity of four wild edible fruits from Mozambique: Adansonia digitata (AD), Dialium schlechteri (DS), Garcinia livingstonei (GL), and Syzygium cordatum (SC), collected over three consecutive years from seven locations. Antioxidant compounds including total polyphenol content (TPC), total flavonoid content (TFC), and vitamin C

It has been established across several contexts that political attitudes are informed by heritable factors. However, it remains unclear how much of the stability we observe in political attitudes can be ascribed to environmental factors and how much of the stability is due to genetics. In this paper we show, using a unique three-wave panel dataset of twins (N = 2471) spanning ten years, that both

Hållbar mobilitet innebär bland annat att prioritera aktiva färdmedel, närhet och tillgänglighet. Det handlar om mer än minskade utsläpp, det handlar också om att ”sätta människan i centrum”, om att skapa livskraftiga och välmående samhällen för alla, och samtidigt förbättra förutsättningarna för välbefinnande i ett rättvist och jämlikt samhälle, både inom och mellan generationer. Rapporten syftar

The estimation of impulse responses (IRs) is fundamental to various audio applications, including active noise control, telecommunication, and sound zone control. Despite its long history, estimating impulse responses remains challenging when dealing with short signals and with signals having poor spectral excitation. However, in many applications the source is moving such that one has access to s

The spatial impulse response (IR) interpolation problem is of general interest, e.g. for imaging of subsurface structures based on seismic waves, rendering of audio and radar IRs, as well as for numerous spatial audio applications. A commonly used model represents the occurring reflections as equivalent source positions, often being determined using a sparse re-construction framework employing spa

Control of the material microstructure in terms of the grain size is a key component in tailoring material properties of metals and alloys and in creating functionally graded materials. To exert this control, reliable and efficient modeling and simulation of the recrystallization process whereby the grain size evolves is vital. The present contribution is a review paper, summarizing the current st

A cellular automaton algorithm with probabilistic cell switches is employed in the simulation of dynamic discontinuous recrystallization. Recrystallization kinetics are formulated on a microlevel where, once nucleated, new grains grow under the driving pressure available from the competing processes of stored energy minimization and boundary energy reduction. Simulations of the microstructural cha

A measurement of the invisible width of the Z boson using events with jets and missing transverse momentum is presented using 37 fb−1 of 13 TeV proton–proton data collected by the ATLAS detector in 2015 and 2016. The ratio of Z→inv to Z→ℓℓ events, where inv refers to non-detected particles and ℓ is either an electron or a muon, is measured and corrected for detector effects. Events with at least o

Controlling the water level in irrigation channels is important for the efficient management of irrigation and water delivery. In this study, the proportional–integral–derivative (PID) controller was implemented in both the HEC-RAS boundary condition, as an internal model, and MATLAB, as an external model. In the latter, the Hydrologic Engineering Center’s (HEC) River Analysis System (HEC-RAS) mod
