We present a synchronized multisensory dataset for accurate and robust indoor localization: the Lund University Vision, Radio, and Audio (LuViRA) Dataset. The dataset includes color images, corresponding depth maps, inertial measurement unit (IMU) readings, channel response between a 5G massive multiple-input and multiple-output (MIMO) testbed and user equipment, audio recorded by 12 microphones,
Provision of assistive technologies (AT) is strongly connected to applying a person-centred approach, with focus on exploring the person’s individual abilities, needs and desires, to enable provision of matching AT. In the process of provision, it is also important to assess and facilitate the person’s understanding of how to use the AT, to enhance optimal usage and enable AT integration in everyd
HfO2, one of the most common materials in resistive switching devices, can stabilize in a ferroelectric orthorhombic phase, enabling two nonvolatile polarization states via oxygen displacement in the unit cell. Under certain conditions, ferroelectric and resistive switching can coexist, independently addressable, within one device. This study employs operando spectroscopic analysis to elucidate th
Under 2023 tilldelades Emma Pihl Skoog, lektor i arkivvetenskap vid Södertörns högskola, och Ann-Sofie Klareld, lektor i arkivvetenskap vid Lunds universitet, ett stipendium från Stiftelsen Riksarkivarie Ingvar Anderssons fond. Syftet var blandannat att färdigställa en forskningsartikel om arkivariers arbetsuppgifter och de kompetenser som efterfrågas i samtida platsannonser på Arbetsförmedlingens
Lean construction principles have been successfully adopted in a variety of industries to increase project management quality. This paper addresses maintenance planning in Sweden and analyses its effectiveness in the framework of lean construction principles. To investigate the status and improvement potential of maintenance contractors’ performance, the study focuses on the detailed planning proc
Nanochains (NCs) made up of a one-dimensional arrangement of magnetic anoparticles (NPs) exhibit anisotropic properties with potential for various applications. Herein, using a novel self-assembly method we directly integrate single NCs onto desired substrates including devices. We present a nanoscopic analysis of magnetization reversal in 1D linear NP arrays by combining x-ray microscopy, magnet
Background: Spirometry reference values differ by race/ethnicity, which is controversial. We evaluated the effect of race-specific references on prevalence of lung function impairment and its relation to breathlessness and mortality in the US population. Methods: Population-based analysis of the National Health and Nutrition Examination Survey (NHANES) 2007–2012. Race/ethnicity was analyzed as bla
In this paper we revisit positioning from Doppler measurements, using techniques from algebraic geometry to produce new theoretical insights and efficient localization algorithms. First, we give a full characterization of the problem, identifying for each problem their minimal configurations, that is the minimum number of receivers and transmitters to have a finite number of solutions. We also stu
The ability to interpret and comprehend a 3D scene is essential for many vision and robotics systems. In numerous applications, this involves 3D object detection, i.e. identifying the location and dimensions of objects belonging to a specific category, typically represented as bounding boxes. This has traditionally been solved by training to detect a fixed set of categories, which limits its use.
Centret för navigation i hjärnan hos ett bi I hjärnan hos ett litet bi som kallas Megalopta genalis finns en del som utgör centret för bland annat navigation. Detta navigationscenter benämns det centrala komplexet och ligger bakom de sofistikerade sätt som denna lilla organism förflyttar sig på i sin omvärld. Det har forskats på det centrala komplexet under flera år och nyligen kartlade några for
Som minst är alltid 5% av jordens yta täckt av havsis. Det gör att isen har en avgörande roll i klimatet, särskilt vid polerna, då den påverkar utbytet av värme, massa och rörelse mellan havet och atmosfären. Ett snötäcke ovanpå isen förstärker ytterligare effekterna av isolering och reflektion. Havsisen och snön är av stor betydelse för det globala klimatsystemet. Dock är det svårt att inhämta dThe sea ice covers approximately 5% of the Earth’s surface at any given time and it plays an important role in the polar climate system affecting the heat, mass and momentum exchange between the atmosphere and the ocean. The snow cover on top of the sea ice affects its insulating and reflective properties and thus key figures in the climate system feedback loop. Sea ice and snow is of significant
We aimed to estimate and compare within-day energy balance (WDEB) in athletes with eumenorrhea and menstrual dysfunction (MD) with similar 24-hour energy availability/energy balance (EA/EB). Furthermore, to investigate whether within-day energy deficiency is associated with resting metabolic rate (RMR), body-composition, S-cortisol, estradiol, T3 , and fasting blood glucose. We reanalyzed 7-day di
Bosonic strings can be discretized in terms of dynamically triangulatedrandom surfaces. We investigate the possibility of introducing fermionicdegrees of freedom on the surface in terms of Ising spins, which in twodimensions correspond to Majorana fermions. Critical properties of themodel are estimated using finite-size scaling methods.
Choice blindness is a cognitive phenomenon describing that when people receive false feedback about a choice they just made, they often accept the outcome as their own. Little is known about what predisposes people to correct manipulations they are subjected to in choice blindness studies. In this study, 118 participants answered a political attitude survey and were then asked to explain some of t
Circuits of multiple deterministically positioned semiconductor nanowires (NWs) is the basis of many devices for photonic, quantum, or conventional transistor applications. To explore and iterate on the design of larger circuits, the means to quickly place and electrically evaluate NWs at target locations must be developed. We propose and demonstrate a multi-NW circuit building concept on SiO2/Si
