Unmanned Aerial Vehicles as Data Mules: An Experimental Assessment
(Journal article; Peer reviewed, 2017)Communication in remote locations, specially in high-latitude regions, such as the Arctic, is challenged by the lack of infrastructures and by the limited availability of resources. However, these regions have high scientific ... -
Unmanned Aerial Vehicles for Air Pollution Monitoring: A Survey
(Peer reviewed; Journal article, 2023)Unmanned aerial vehicles (UAVs) equipped with air quality sensors offer a powerful solution for increasing the spatial and temporal resolution of air quality data, searching and detecting emission sources, and monitoring ... -
Unmanned Aircraft Flight Control Aided by Phased-Array Radio Navigation
(Peer reviewed; Journal article, 2020)Navigation systems of safety‐critical unmanned aircraft need an alternative position aiding source to global navigation satellite system. One promising alternative, is position measurements from phased‐array radio systems. ... -
Unmanned autonomous vessels and the necessity of human-centred design
(Chapter, 2020)Unmanned autonomous vessels are said to be the future of the shipping industry. Besides lowering cost and emissions, it is also said to lower the accidents attributed to human error completely. Still, the first unmanned ... -

Unmanned vehicle and hyperspectral imager for a more rapid microplastics sampling and analysis.
(Journal article, 2023)In this paper, we present a proof-of-concept study aiming to improve the sampling and analysis of microplastics (MPs) by implementing a novel methodology combining an autonomous surface vehicle and a near-infrared hyperspectral ... -
Unmanned Water Craft Identification and Adaptive Control in Low-Speed and Reversing Regions
(Journal article; Peer reviewed, 2013)This paper treats L1 adaptive hovering control of an unmanned surface vehicle in a station-keeping mode where a region of zero control authority and under-actuation are main challenges. Low-speed and reversing dynamics are ... -
Unmentioned Challenges of Finnish Teacher Education: Decontextualisation, Scientification and the Rhetoric of the Research-Based Agenda
(Chapter, 2023)Finnish teacher education has emphasised that academic standards and a research-based agenda are followed in the everyday activities of training teachers. Finnish teacher education has been recognised as a prime example ... -
Unmuting the organization through serious play
(Peer reviewed; Journal article, 2020)In this article, we sketch up an action research process designed to give voice to those who traditionally have not had a voice in organizations. In particular, the research process was structured around “serious play” and ... -
Unpacking Ethnicity: Exploring the Underlying Mechanisms Linking Ethnic Fractionalization and Civil Conflict
(Journal article; Peer reviewed, 2016)In the study of civil conflict, many regard ethnic fractionalization as a measure of grievance. However, there is also a rational-actor explanation as to why ethnicity might cause rebellion. A third possibility is that ... -
Unpacking Healthcare Professionals’ Work to Achieve Coherence in the Healthcare Journey of Elderly Patients: An Interview Study
(Peer reviewed; Journal article, 2021)Aim: Today, seamless, person-centered healthcare is emphasized when dealing with elderly patients with comprehensive needs. Studies have uncovered a complex healthcare terrain. Despite a great deal of effort on the part ... -
Unpacking the Public Health Triad of Social Inequality in Health, Health Literacy, and Quality of Life—A Scoping Review of Research Characteristics
(Peer reviewed; Journal article, 2023)Social inequalities in health, health literacy, and quality of life serve as distinct public health indicators, but it remains unclear how and to what extent they are applied and combined in the literature. Thus, the ... -
Unpacking the ‘15-Minute City’ via 6G, IoT, and Digital Twins: Towards a New Narrative for Increasing Urban Efficiency, Resilience, and Sustainability
(Peer reviewed; Journal article, 2022)The ‘15-minute city’ concept is emerging as a potent urban regeneration model in post-pandemic cities, offering new vantage points on liveability and urban health. While the concept is primarily geared towards rethinking ... -
Unravel the Local Complexity of Biological Environments by MALDI Mass Spectrometry Imaging
(Peer reviewed; Journal article, 2021)Classic metabolomic methods have proven to be very useful to study functional biology and variation in the chemical composition of different tissues. However, they do not provide any information in terms of spatial ... -
Unraveling adhesion strength between gas hydrate and solid surfaces
(Peer reviewed; Journal article, 2021)Natural gas hydrate is a promising future energy source, but it also poses a huge threat to oil and gas production due to its ability to deposit within and block pipelines. Understanding the atomistic mechanisms of adhesion ... -
Unraveling catalytic properties by yttrium promotion on mesoporous SBA-16 supported nickel catalysts towards CO2 methanation
(Peer reviewed; Journal article, 2021)The ordered mesoporous silica SBA-16 with high specific surface area and pore volume was synthesized and used to prepare Ni/SBA-16 catalysts promoted with yttrium. These promoted catalysts were tested in CO2 methanation ... -
