Unravelling the prospective associations between mixed anxiety-depression and insomnia during the course of cognitive behavioral therapy
(Journal article; Peer reviewed, 2019)Objective Previous studies have suggested that there is a reciprocal relationship between anxiety/depression and insomnia. However, little is known about the prospective relationships between these constructs across the ... -
Unrecognized viral infections and chromosome abnormalities as a cause of fetal death – examination with fluorescence in situ hybridization, immunohistochemistry and polymerase chain reaction
(Journal article; Peer reviewed, 2017)Fifteen to 50% of fetal deaths remain unexplained after post-mortem examination depending on inclusion criteria and classification systems. Our aim was to examine a selection of unexplained fetal deaths in order to investigate ... -
Unreined Students or Not: Modes of Freedom in a Project-Based Software Engineering Course
(Journal article, 2020)Software engineering courses include practical and theoretical elements that give many options for pedagogical combinations among them. In this paper, we report on two different pedagogical approaches for an undergraduate, ... -
Unscented Kalman Filter Based State and Parameter Estimation in Percussive Drilling Systems
(Chapter, 2020)Down-The-Hole (DTH) percussion tool is recognized for its high average rate of penetration (ROP), when drilling medium hard to very hard rock formations. This ROP which depends on the bit-rock contact conditions at the ... -
Unscented Multi-Point Smoother for Fusion of Delayed Displacement Measurements: Application to Agricultural Robots
(Journal article; Peer reviewed, 2017)Visual Odometry (VO) is increasingly a useful tool for robotic navigation in a variety of applications, including weed removal for agricultural robotics. The methods of evaluating VO are often computationally expensive and ... -
Unsettled settlement? Translocal social anchoring and patterns of (im)mobility among Polish families in rural Norway
(Peer reviewed; Journal article, 2021)Whilst the transnational family life of post-accession intra-European migrants has been extensively explored, past studies have rarely addressed its local dimension. The relatively recent international migration patterns ... -

The Unstable Object: Glifo, Blow, and Sacco at MoMA, 1972
(Peer reviewed; Journal article, 2020)This article discusses three radical objects—the Glifo shelf from 1966, the Blow chair from 1967 and the Sacco chair from 1968—that were all exhibited at Museum of Modern Art’s ground-breaking architecture and design ... -
Unstable splittings in Hodge filtered Brown-Peterson cohomology
(Journal article, 2018)We construct Hodge filtered function spaces associated to infinite loop spaces. For Brown–Peterson cohomology, we show that the corresponding Hodge filtered spaces satisfy an analog of Wilson’s unstable splitting. As a ... -
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. ...
