We present a user study analyzing head-gaze- based robot control and foveated visual augmentation in a simulated search-and-rescue task. Results show that foveated augmentation significantly improves task performance, reduces cognitive load by 38%, and shortens task time by over 60%. Head-gaze patterns analysed over both the entire task duration and shorter time segments show that near and far att
Portable optically stimulated luminescence (pOSL) analysis allows rapid relative dating of sediments that potentially can be calibrated against known OSL ages to provide an age estimate for landforms across a large area. This study uses 186 pOSL measurements and 20 OSL ages to investigate the postglacial landscape evolution inside the Younger Dryas moraines in NE Finnmark and Finnish Lapland. Aeol
This paper investigates the detection of permittivity defects in a fabricated, known object, motivated by a desire to detect errors in additively manufactured objects that may affect their electromagnetic performance. We use scattering parameter sensitivities to reconstruct the relative permittivity of a generic 2D object from microwave scattering measurements and a known reference model. To find
To address the absence of the comprehensive analysis of energy-water-carbon emissions nexus between large-scale economies and different industries and the inability to predict policy impacts across industrial hierarchies, this study develops a novel framework integrating environmentally-extended multi-regional input-output analysis with structural decomposition analysis and policy-driven scenario
When searching for an object in my pocket, I can clearly perceive the edges, shape, and hardness of the items I touch — regardless of which part of my fingers makes contact and despite large sensorimotor noise. What accounts for these perceptual invariants? Vincent Hayward introduced key elements to investigate this question, by (i) analyzing mechanical spatiotemporal invariants emerging from the
This article analyzes the effects of self-balancing in multiactive bridge converters. Therefore, it proposes a time-domain approach to model the dynamics of multiwinding transformer-based multilevel dc/dc converter, including self-balancing. In previous research, multiwinding transformers have been modeled using average-based power transfer models. These models, while simple, have no direct intuit
Purpose: The aim of this study was to evaluate the feasibility and mid-term results of combining polytetrafluoroethylene (PTFE)-based iliac limbs, having a short dilator tip, with a polyester (Dacron)-based bifurcated component during a fenestrated endovascular aortic repair (FEVAR).Materials and methods: All patients who underwent a FEVAR procedure in a single tertiary center were screened for in
Cell encapsulation provides an efficient strategy to enhance cell durability against harsh external conditions, that offers new possibilities for single-cell applications, such as, tissue engineering and regenerative medicine. Cell encapsulations in hydrogels is developed through various approaches. Still, it remains challenging to achieve single-cell encapsulation where the individual cells are s
Three rotational bands have been discovered in the nucleus Sb109 that extend in angular momentum to 81/2Latin small letter h with stroke. The rotational frequency at the highest spins reaches Latin small letter h with strokeω1.4 MeV, the highest frequency so far observed in a heavy nucleus. With increasing frequency the collective moments of inertia of all three bands smoothly diminish to unexpect
Lifetime measurements for the isotopes 155Dy and 156Dy have been extended up to spins around 40h{stroke} by the Doppler shift attenuation method in conjunction with γ-γ-coincidence measurements. Results have been obtained for the yrast band in 156Dy and for three bands in 155Dy. Strong retardations of the E2-strengt were observed for intruding terminating sequences, for which specific single parti
The collective and non-collective high-spin configurations in selected A {reversed tilde equals} 80 nuclei are analysed in detail using a shell-correction approach taking care of individual configurations and the pairing self-consistent cranking method with a non-axially-deformed Woods-Saxon potential. Shape transitions, shape coexistence, band-termination effects and alignment processes are discu
Background: Mucin degradation is essential for understanding oral microbial adaptation, yet the enzymes involved remain incompletely understood. Herein, we have characterised two mucin-degrading proteases, MdpS and MdpS2, from the oral commensal Streptococcus oralis. Materials and methods: MdpS2 was characterised using physicochemical assays and substrate profiling and was compared to MdpS. Furthe
Aqueous solutions are crucial in chemistry, biology, environmental science, and technology. The chemistry of solutes is influenced by the surrounding solvation shell of water molecules, which have different chemical properties than bulk water due to their different electronic and geometric structure. It is experimentally challenging to selectively investigate this property-determining electronic a
The company that this project takes place at has most of its production facility in Halmstad. A little more than a year ago this plant was exposed to a fire that destroyed the facility completely. The company is now planning to build a new plant on the same spot as the old was situated. Purpose The purpose of this project is to analyse the company´s material flow and based on the result make decis
Due to global demand for alternative energy sources, the industry of hydropower is continuing to thrive. Not only are there already thousands of dams worldwide, but many more developments are planned for the future. This has increased attention towards the topic of reservoirs, and more specifically their potential to act as a source of greenhouse gases. Despite tropical locations being known as ‘h
In the last couple of decades, it has become apparent in ecology that community structure can be governed by both local (e.g. abiotic and biotic filtering) and regional processes (e.g. dispersal) – known as Metacommunity theory. However, management and restoration projects have lagged, still mostly focusing on the local environment for the benefit of certain species or communities – leading to fai
The purpose of this master thesis was to increase the understanding of the role of gender in the Gig Economy. This research followed a social constructivist approach with an abductive mechanism that allowed for parallel working with theory and empirical data. Ten in-depth semi-structured interviews build the foundation for the research in this thesis. With the metaphor of ‘walking barefoot’, this
