R-PCNN Method to Rapidly Detect Objects on THz Images in Human Body Security Checks
(Chapter, 2018)Terahertz human body security images have low resolution and a low signal-to-noise ratio. In the traditional method, image segmentation, positioning, and identification are applied to detect objects carried by humans in ... -
R.Graph: A new risk-based causal reasoning and its application to COVID-19 risk analysis
(Journal article; Peer reviewed, 2022) -
R1352Q CACNA1A variant in a patient with sporadic hemiplegic migrainem ataxia, seizures and cerebral oedema: A case report
(Journal article; Peer reviewed, 2021)Mutations in the CACNA1A gene show a wide range of neurological phenotypes including hemiplegic migraine, ataxia, mental retardation and epilepsy. In some cases, hemiplegic migraine attacks can be triggered by minor head ... -
R2* Relaxation Affects Pharmacokinetic Analysis of Dynamic Contrast-Enhanced MRI in Cancer and Underestimates Treatment Response at 7 T
(Journal article, 2019)Effective transverse relaxivity of gadolinium-based contrast agents is often neglected in dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Here, we assess time and tissue dependence of R2* enhancement and ... -
R744 ejector technology future perspectives
(Journal article; Peer reviewed, 2016)Carbon Dioxide, CO2 (R744) was one of the first commonly applied working fluids in the infancy of refrigeration more than 100 years ago. In contrast to ammonia it mainly disappeared after the first generation of synthetic ... -
R744 heat pump solutions for electric vehicles
(Chapter, 2023) -
R744 Refrigeration Solution for Small Supermarkets
(Chapter, 2021)Application based technology solution is nowadays preferred to achieve the performance of the cooling system configuration at its best. Therefore, benchmarking is an essential criterion which would add value to the optimum ... -
Race and Employment: The Historical Case of Head Coaches in College Basketball
(Peer reviewed; Journal article, 2020)This study analyzes how the number of Black coaches in college basketball has evolved since 1947. The analysis puts a focus on the time period after 1973 when regulatory requirements changed and a new Division was established. ... -
Race and Process: Certifying Iberian Pigs and Invisibilising Humans
(Journal article; Peer reviewed, 2019)This article is based on on-going fieldwork in Extremadura, Spain and printed material produced by the producers’ association: a producer’s handbook, a guide to the genealogical registry, a trade journal, and current ... -
Race development and performance-determining factors in a mass-start cross-country skiing competition
(Journal article; Peer reviewed, 2023)Although five of six Olympic events in cross-country skiing involve mass-starts, those events are sparsely examined scientifically. Therefore, in this study, we investigated speed profiles, pacing strategies, group dynamics ... -
The Race to Realize Small Modular Reactors: Rapid Deployment of Clean Dispatchable Energy Sources
(Journal article; Peer reviewed, 2024)Small modular reactors (SMRs) are currently touted as the next evolution of nuclear energy. They are a type of nuclear reactor designed to be smaller in size than a traditional reactor. Nevertheless, they are based on the ... -
Radar-based Maritime Collision Avoidance using Dynamic Window
(Journal article; Peer reviewed, 2018)Collision avoidance systems are a key ingredient in developing autonomous surface vehicles (ASVs). Such systems require real-time information about the environment, which can be obtained from transponder-based systems or ... -
Radial intersection count image: A clutter resistant 3D shape descriptor
(Peer reviewed; Journal article, 2020)A novel shape descriptor for cluttered scenes is presented, the Radial Intersection Count Image (RICI), and is shown to significantly outperform the classic Spin Image (SI) and 3D Shape Context (3DSC) in both uncluttered ... -
Radiative forcing bias of simulated surface albedo modifications linked to forest cover changes at northern latitudes
(Journal article; Peer reviewed, 2015)In the presence of snow, the bias in the prediction of surface albedo by many climate models remains difficult to correct due to the difficulties of separating the albedo parameterizations from those describing snow and ... -
Radiative forcing geoengineering causes higher risk of wildfires and permafrost thawing over the Arctic regions
(Journal article; Peer reviewed, 2024)Radiative forcing geoengineering is discussed as an intermediate solution to partially offset greenhouse gas-driven warming by altering the Earth’s energy budget. Here we use an Earth System Model to analyse the response ... -
The radically unequal distribution of Covid-19 vaccinations: a predictable yet avoidable symptom of the fundamental causes of inequality
(Peer reviewed; Journal article, 2022)The Covid-19 pandemic—and its social and economic fallout—has thrust social and health-related inequalities into the spotlight. The pandemic, and our response to it, has induced new inequalities both within and between ... -
Radio frequency backscatter communication for high data rate deep implants
(Journal article; Peer reviewed, 2019)In this paper, we study the radio frequency (RF) backscatter for high data rate wireless communication with deep medical implants. The radar approach permits remote reading of the implant's information. This means that the ... -
Radio frequency measurements and capacity analysis for industrial indoor environments
(Chapter, 2015)In this study, path-loss and shadowing measurement results for three different industrial indoor environments at 900, 1600, and 2450 MHz are presented. The results show that the one-slope model fits the measured path-loss ... -
