U-Compare bio-event meta-service: compatible BioNLP event extraction services
(Journal article; Peer reviewed, 2011)Background: Bio-molecular event extraction from literature is recognized as an important task of bio text mining and, as such, many relevant systems have been developed and made available during the last decade. While ... -
The U-Net Family for Epicardial Adipose Tissue Segmentation and Quantification in Low-Dose CT
(Peer reviewed; Journal article, 2023)Epicardial adipose tissue (EAT) is located between the visceral pericardium and myocardium, and EAT volume is correlated with cardiovascular risk. Nowadays, many deep learning-based automated EAT segmentation and quantification ... -

U-shaped Trajectories in an L2 context: Evidence from the acquisition of verb morphology
(Peer reviewed; Journal article, 2022)This study explores U-shaped behaviour in the acquisition of irregular verb morphology across three groups of Norwegian L2 learners of English. This phenomenon is especially interesting due to its significance for the ... -
The U.S. coal sector between shale gas and renewables: Last resort coal exports?
(Peer reviewed; Journal article, 2020)Coal consumption and production have sharply declined in recent years in the U.S., despite political support. Reasons are mostly unfavorable economic conditions for coal, including competition from natural gas and renewables ... -
U.S. Multinationals and Human Rights: A Theoretical and Empirical Assessment of Extractive Versus Nonextractive Sectors
(Peer reviewed; Journal article, 2020)The consequences of foreign direct investment (FDI) for human rights protection are poorly understood. We propose that the impact of FDI varies across industries. In particular, extractive firms in the oil and mining ... -
UAM Icing: Ice Accretion Experiments and CFD Icing Simulations on Rotors for eVTOL Unmanned Aircraft
(Peer reviewed; Journal article, 2023) -
UAV Fault-Tolerant Control by Combined L1 Adaptive Backstepping and Fault-dependent Control Allocation
(Chapter, 2015)This paper presents an approach to obtain fault tolerance in the nonlinear longitudinal motion control of an aircraft. The approach uses an L1 adaptive backstepping controller and fault-dependent control allocation to ... -
UAV Icing: A Performance Model for a UAV Propeller in Icing Conditions
(Chapter, 2022)In-flight icing on unmanned aerial vehicles is a severe hazard and imposes limits on the operational envelope. Icing has been shown to lead to substantial aerodynamic performance losses on lifting surfaces and propellers. ... -
UAV Icing: A Unified Icing Severity Index Derived from Performance Degradation
(Chapter, 2022)A problem that unmanned aerial vehicles (UAV) operators face when dealing with in-flight icing conditions is a reliable way to assess icing severity risk. This paper aims to develop an icing severity index that looks at ... -
UAV icing: Development of an ice protection system for the propeller of a small UAV
(Journal article; Peer reviewed, 2023)Atmospheric icing, also called in-flight icing, is a common hazard for the operation of uncrewed aerial vehicles (UAVs). With the background of a growing commercial and military market of small and medium-sized drones and ... -
UAV Icing: Experimental validation data for predicting ice shapes at low Reynolds numbers
(Peer reviewed; Journal article, 2023) -
UAV Icing: Ice Accretion Experiments and Validation
(Journal article; Peer reviewed, 2019)Atmospheric icing is a key challenge to the operational envelope of medium-sized fixed-wing UAVs. Today, several numeric icing codes exist, that all have been developed for general aviation applications. UAVs with wingspans ... -
UAV Icing: Ice Shedding Detection Methods for an Electrothermal De-Icing System
(Chapter, 2022)Among the identified problems with unmanned aerial vehicles (UAVs), especially with the medium-sized fixed-wing UAVs, is a lack of mature ice protection systems (IPSs). One of the emerging UAV ice protection technologies ... -
UAV Icing: Icing Cases for Validation of Path Planning Method
(Peer reviewed; Journal article, 2023)As part of the complete solution to deal with atmospheric in-flight icing on unmanned aerial vehicles (UAV), a path planner is a valuable tool for finding an optimal path for accomplishing UAV missions. When considering ... -
UAV Icing: Intercycle Ice Effects on Aerodynamic Performance
(Peer reviewed; Journal article, 2023)Atmospheric in-flight icing poses a challenge to all aircraft including unmanned aerial vehicles (UAVs). Aircraft should avoid icing conditions unless they have ways of mitigating the negative effects of icing, e.g., if ... -
UAV Icing: Numerical Simulation of Icing Effects on Wing and Empennage
(Peer reviewed; Journal article, 2023)In-flight icing can result in severe aerodynamic performance penalties for unmanned aerial vehicles. It is therefore important to understand to which extent ice will build up on fixed-wing unmanned aerial vehicles wings ... -
UAV LiDAR in coastal environments: Archaeological case studies from Tierra del Fuego, Argentina, and Vega, Norway
(Peer reviewed; Journal article, 2023)LiDAR has become fairly integrated into archaeological practice at a global scale. This has gradually evolved to include UAV LiDAR. Nevertheless, considerable biases remain, including with regard to geographical regions, ... -
UAV path planning using MILP with experiments
(Journal article; Peer reviewed, 2017)In this paper, we look at the problem of tracking icebergs using multiple Unmanned Aerial Vehicles (UAVs). Our solutions use combinatorial optimization for UAV path planning by formulating a mixed integer linear programing ... -
UAV-enabled data acquisition scheme with directional wireless energy transfer for Internet of Things
