Thermodynamic correction of particle concentrations measured by underwing probes on fast-flying aircraft
2016
Particle concentration measurements with underwing probes on aircraft are impacted by air compression upstream of the instrument body as a function of flight velocity. In particular, for fast-flying aircraft the necessity arises to account for compression of the air sample volume. Hence, a correction procedure is needed to invert measured particle number concentrations to ambient conditions that is commonly applicable to different instruments to gain comparable results. In the compression region where the detection of particles occurs (i.e. under factual measurement conditions), pressure and temperature of the air sample are increased compared to ambient (undisturbed) conditions in certain …
DinosARs - Learning with the help of augmented reality
2019
Master's thesis Multimedia and Educational Technology MM500 - University of Agder 2019 A two-dimensional way of interacting with learning material has been the norm fora long time. We’ve read books, taken notes and been taught from a blackboard sinceyouth, and has for most of us worked out just fine, but we are all different. We havethose visual learners, those who learn through seeing things, auditory learners, thosewho learn best through hearing and kinesthetic learners, those who learn by doing.Augmented reality can provide many unique affordances that can deliver a learningexperience that can benefit all learning types. Augmented reality can utilize both vi-suals, sound, and interactivi…
Temperature effects explain continental scale distribution of cyanobacterial toxins
2018
Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention is given to other classes, such as neurotoxins (e.g., anatoxin-a) and cytotoxins (e.g., cylindrospermopsin) due to their potency. Most studies examine the relationship between individual toxin variants and environmental factors, such as nutrients, temperature and light. In summer 2015, we collected samples across Europe to investigate the effect of nutrient and temperature gradients on the variability of toxin production at a continental scale. Direct and indirect…

The Junta de Damas de Honor y Mérito (Committee of Ladies of Honour and Merit): Children’s parchments in the Madrid Foundling House (1802)
2023
A finales del siglo XVIII, la Casa de Expósitos de Madrid recibía unos tres o cuatro bebés al día, aproximadamente mil al año. Las tasas de mortalidad eran enormes: más del 90% de los niños morían durante el primer mes de vida. En 1799, una sociedad femenina, la Junta de Damas de Honor y Mérito, sustituyó al anterior comité masculino y asumió la totalidad de las funciones. Este capítulo muestra cómo utilizar la documentación elaborada por la Junta como fuente primaria para recurrir a sus prácticas científicas con el fin de reducir los índices de mortalidad. By the late eighteenth century, the Madrid Foundling House received around three to four babies a day, approximately a thousand babies …
Smartphone usage among older adults
2021
Abstract Problematic smartphone usage, associated with impaired daily functioning, has gained increased attention among researchers. However, extant research is focusing on adolescents and younger adults. This paper investigates smartphone usage among older adults, of which less is known. To do so, we conducted a cross-sectional survey of 154 smartphone users (60+ years) in Norway using structural equation modeling (PLS-SEM). We examined the contributing roles of loneliness, habit, social influence, emotional gain, fear of missing out, self-control, and problematic smartphone usage. We further investigated how older adults engage with their smartphones. Our findings suggest that older adult…
Medisinsk avstandsoppfølging for pasienter med epilepsi : En kvalitativ studie om pasienter med epilepsi sine opplevelser, erfaringer og tanker om ny…
2020
Master's thesis in Health informatics (HSI500) Background There is an increasing focus on the use of medical distance monitoring to improve the quality of patient care and increase the effectiveness of health care. Digital PRO-based solution is a new service for patients with epilepsy. The digital form the patient fills out is used as the basis for outpatient follow-up. Purpose The purpose of this study is to contribute knowledge to whether patients with epilepsy experience benefits of medical distance monitoring. The problem statement in the study was: "What experiences and thoughts do patients with epilepsy have about the utility of medical distance follow-up?" Selection and methodologyTh…
Fastlegers informasjonsbehov ved medisinsk avstandsoppfølging : En kvalitativ studie
2019
Masteroppgave helse- og sosialinformatikk HSI500 - Universitetet i Agder 2019 Bakgrunn:For å møte den fremtidige økningen i forekomsten av ikke-smittsomme kroniske sykdommerhar Norge prøvd utmedisinsk avstandsoppfølging siden2016. Resultatene så langt viser en økt trygghet, samt følelse av oppfølging og kontroll over egen helse hos pasientene. Det understrekes at det å involvere fastleger i tjenestene har vært utfordrende(Helsedirektoratet, 2018a). Videreutprøvingble startet opp i 2018 og er planlagt å fortsette til og med2021. Hensikt:Formålet med denne masteroppgaven er å bidra med kunnskap om hvordan IKT best mulig kan understøtte fastlegenes tiltenkte rolle som koordinator i medisinsk a…
Localization of Multi-Class On-Road and Aerial Targets Using mmWave FMCW Radar
2021
mmWave radars play a vital role in autonomous systems, such as unmanned aerial vehicles (UAVs), unmanned surface vehicles (USVs), ground station control and monitoring systems. The challenging task when using mmWave radars is to estimate the accurate angle of arrival (AoA) of the targets, due to the limited number of receivers. In this paper, we present a novel AoA estimation technique, using mmWave FMCW radars operating in the frequency range 77–81 GHz by utilizing the mechanical rotation. Rotating the radar also increases the field of view in both azimuth and elevation. The proposed method estimates the AoA of the targets, using only a single transmitter and receiver. The measurements are…
Tapology: A Game-Based Platform to Facilitate E-Health and E-Inclusion

Also available from the publisher at: http://dx.doi.org/10.1007/978-3-319-07446-7_36 We have developed a tablet computer game app for low vision users that can be used to introduce a platform for gaming, internet and visual rehabilitation to older users who have not had prior experience with information communication technology (ICT). Our target user group is people diagnosed with Age Related Macular Degeneration (AMD). The primary goal of the app is to present a fun and engaging means for participants to engage with Information Communication Technology (ICT). A long…
