Unsteady hydrodynamic forces of solid objects vertically entering the water surface
(Journal article; Peer reviewed, 2019)We investigate the unsteady hydrodynamic force of solid objects vertically entering water with an air cavity behind the falling body. Physical models are proposed to represent the force components corresponding to the body ... -
Unstructured Voronoi grids conforming to lower-dimensional objects
(Journal article; Peer reviewed, 2018)We present a novel mixed-dimensional method for generating unstructured polyhedral grids that conform to prescribed geometric objects in arbitrary dimensions. Two types of conformity are introduced: (i) control-point ... -
Unsupervised Anomaly Detection for IoT-Based Multivariate Time Series: Existing Solutions, Performance Analysis and Future Directions
(Peer reviewed; Journal article, 2023)The recent wave of digitalization is characterized by the widespread deployment of sensors in many different environments, e.g., multi-sensor systems represent a critical enabling technology towards full autonomy in ... -
Unsupervised clustering for works of art using hyperspectral imaging: A case study on Edvard Munch's Self-Portrait (1905)
(Journal article; Peer reviewed, 2023)The study of pigments in historical works of art is of significant value for conservators and art historians, providing insight into artistic techniques and the preservation of cultural heritage. Hyperspectral imaging aids ... -
Unsupervised Clustering of Hyperspectral Paper Data Using t-SNE
(Peer reviewed; Journal article, 2020)For a suspected forgery that involves the falsification of a document or its contents, the investigator will primarily analyze the document’s paper and ink in order to establish the authenticity of the subject under ... -
Unsupervised Denoising for Super-Resolution (UDSR) of Real-World Images
(Peer reviewed; Journal article, 2022)Single Image Super-Resolution (SISR) using Convolutional Neural Networks (CNNs) for many applications in supervised manner has resulted in significant improvement in state-of-the-art performance. Such supervised models ... -
Unsupervised human action retrieval using salient points in 3D mesh sequences
(Journal article, 2018)The problem of human action retrieval based on the representation of the human body as a 3D mesh is addressed. The proposed 3D mesh sequence descriptor is based on a set of trajectories of salient points of the human body: ... -
Unsupervised machine learning applied to scanning precession electron diffraction data
(Journal article; Peer reviewed, 2019)Scanning precession electron diffraction involves the acquisition of a two-dimensional precession electron diffraction pattern at every probe position in a two-dimensional scan. The data typically comprise many more ... -
Unsupervised supervoxel-based lung tumor segmentation across patient scans in hybrid PET/MRI
(Peer reviewed; Journal article, 2020)Tumor segmentation is a crucial but difficult task in treatment planning and follow-up of cancerous patients. The challenge of automating the tumor segmentation has recently received a lot of attention, but the potential ... -
Untangling the Concepts of Value and Values
(Chapter, 2023)The concept of value is widely used in lean construction (LC) literature, but researchers and practitioners lack a common understanding of the term. This is partially due to confusion between value (singular) and values ... -
Untargeted metabolomic analysis of urine samples in the diagnosis of some inherited metabolic disorders
(Peer reviewed; Journal article, 2015)Background: Metabolomics is becoming an important tool in clinical research and the diagnosis of human diseases. It has been used in the diagnosis of inherited metabolic disorders with pronounced biochemical abnormalities. ... -

Unveiling bulk and surface radiation forces in a dielectric liquid
(Peer reviewed; Journal article, 2022)Precise control over light-matter interactions is critical for many optical manipulation and material characterization methodologies, further playing a paramount role in a host of nanotechnology applications. Nonetheless, ... -
Unveiling the Nature of Galactic TeV Sources with IceCube Results
(Peer reviewed; Journal article, 2023)IceCube collaboration reported the first high-significance observation of the neutrino emission from the Galactic disk. The observed signal can be due to diffuse emission produced by cosmic rays interacting with interstellar ... -
Unwanted incidents during transition of geriatric patients from hospital to home: a prospective observational study
(Journal article; Peer reviewed, 2010)Background: Geriatric patients recently discharged from hospital experience increased chance of unplanned readmissions and admission to nursing homes. Several studies have shown that medication-related discrepancies are ... -
UoCAD: An Unsupervised Online Contextual Anomaly Detection Approach for Multivariate Time Series from Smart Homes
(Chapter, 2024)In the context of time series data, a contextual anomaly is considered an event or action that causes a deviation in the data values from the norm. This deviation may appear normal if we do not consider the timestamp ... -
Up- and downgoing borehole wavefield retrieval using single component borehole and reflection data
(Journal article; Peer reviewed, 2018)A standard procedure in processing vertical seismic profile (VSP) data is the separation of up- and downgoing wavefields. We show that these wavefields in boreholes can be retrieved using only single-component data, given ... -
