Rock-cutting processes are the backbone of the mining, oil and gas, civil engineering, and construction industries. Performance of such cutting operations is controlled by temperature-dependent phenomena of abrasion, phase transformations, and oxidation of tooling. This study develops a novel approach for the measurement of cutting temperature for the case of the rock cutting process in longitudin
β-Ga2O3 is a promising ultrawide-bandgap semiconductor for high-power and optoelectronic applications; yet, its intrinsically low thermal conductivity poses challenges for heat dissipation. To clarify how strain and size effects govern phonon transport, we investigate bulk β-Ga2O3 under biaxial tensile strain and finite-size confinement using first-principles calculations and the phonon Boltzmann
It is often argued that design serves as an effective change agent in strategy formation. However, the question of how this actually occurs remains largely unexplored. Through case studies of five design consulting firms in Denmark, this paper examines how design gets involved in the making of strategy. The findings show that there are at least two paths to strategy-level work: First, design works
Collaborating with public or private sector organizations in project-based courses equips design students with key skills to future-proof their careers, but this gives only one side of the story as the key feature of these partnerships is that they are mutualistic collaborations. However, the benefits to organizations of collaborating are not fully explored. This paper presents a case study of par
Public sector organizations have been increasingly turning to design in their pursuit to innovate and address pressing challenges that seem intractable through their existing ways of working. Design’s presence in the public sector is still a relatively recent phenomenon ridden with many challenges. Through a study of three municipalities in Sweden, we present tensions designers face as they work t
The work focuses on Lagrange stability of the origin for the three-state Moore–Greitzer compressor model in closed loop with a nonlinear PI controller, tuned only to stabilize a lower-dimensional invariant surge dynamics subsystem. The linearization of the system is not stabilizable but the static nonlinearity satisfies a sector condition, and together with a structural property of the stall-dynam
Assembly of plasmonic nanoparticles (NPs) generates unique optical properties through coupling of the localized surface plasmon resonance (LSPR) of individual NPs. However, precisely controlling and monitoring how mesoscale assembly dictates final optical properties remain key challenges in designing advanced plasmonic materials. Here, we introduce "nanoplasmonic isosbestics" as optical descriptor
Although Surface Enhanced Raman Scattering (SERS) is widely applied for ultrasensitive diagnostics and imaging, its potential is largely limited by the difficult preparation of SERS tags, typically metallic nanoparticles (NPs) functionalized with Raman-active molecules (RRs), whose production often involves complex synthetic approaches, low colloidal stability and poor reproducibility. Here, we in
In the past decades, events occurring at the nano-bio interface (i.e., where engineered nanoparticles (NPs) meet biological interfaces such as biomembranes) have been intensively investigated, to address the cytotoxicity of nanomaterials and boost their clinical translation. In this field, lamellar synthetic model membranes have been instrumental to disentangle non-specific interactions between NP
David Wojnarowicz (1954–1992) was a multimedia artist, a writer, and an activist. This paper examines how Wojnarowicz navigates the tension between the limitations of language and its use as a medium for articulating his queer life and death through his typewriter and tape recorder. While Wojnarowicz detests language as part of the structural oppression in the US, he relies on language and writing
Denna avhandling undersöker varumärkens transgressiva natur och syftar till att utveckla en konceptuell och teoretisk förståelse av varumärken som distinkta kommunikativa enheter som kan överskrida gränser och möjliggöra sociala relationer. Avhandlingen utvecklar ett kommunikationsfokuserat perspektiv baserat på Niklas Luhmanns sociologiska systemteori. Utifrån detta perspektiv omkonceptualiseras This thesis investigates the transgressive nature of brands and aims to develop a conceptual and theoretical understanding of brands as distinct communicative entities capable of transcending boundaries and facilitating social relations. The thesis develops a communication-centered perspective that draws on Niklas Luhmann’s social systems theory. In doing so, it reconceptualizes brands as communic
Heavy-duty road transport is a major source of greenhouse gas emissions. Decarbonizing long-distance routes is challenging because high-power en-route charging imposes severe grid stress, especially in systems integrating large shares of photovoltaics (PV). Driving-time regulations for truck drivers, such as Japan's mandatory 3 0-minute break, create predictable charging windows. Charging a heavy-
Spatial omics allows for comprehensive investigation of the tumor immune microenvironment (TIME). Stratifying patients by their TIMEs contributes with insights in tumor immune response and has the potential to guide treatment decision-making in the immuno-oncology setting. However, high-plex spatial omics approaches still suffer from high costs and limited direct clinical applicability. We address
This thesis investigates the martensitic phase transformation with the aim of developing predictive models for its formation and evolution under different conditions. The work seeks to provide a fundamental understanding of martensitic transformation through both macroscale continuum modeling and mesoscale crystal plasticity modeling. The continuum modeling considers the austenite to martensite p
In order to meet the demands of consumers, personal care products, like any other product, must undergo constant innovation in order to stay up to date with consumer needs, preferences whilst conforming to commercial regulation. Here, the works contained within this thesis firstly aim to gain greater understanding of current actives in aluminium antiperspirant products, through the manufacture and
