10Be surface exposure dating of the deglaciation of northernmost Norway and Finland
(Peer reviewed; Journal article, 2020)During the Last Glacial Maximum, the coast of Finnmark county, northern Norway, was covered by the Scandinavian Ice Sheet (SIS), which coalesced with the Barents Sea Ice Sheet (BSIS) off the coast. The region is thus ... -
13C and 15N NMR characterization of amine reactivity and solvent effects in CO2 capture
(Journal article; Peer reviewed, 2014)Factors influencing the reactivity of selected amine absorbents for carbon dioxide (CO2) capture, in terms of the tendency to form amine carbamate, have been studied. Four linear primary alkanolamines at varying chain ... -
3-way PLS regression and dual energy gamma densitometry for prediction of total volume fractions and enhanced flow regime identification in multiphase flow
(Journal article; Peer reviewed, 2014-12)Dual energy gamma densitometry and 3-way partial least squares regression were applied to quantify the total volume fractions and improve flow regime identification in multiphase flow. Multiphase flow experiments were ... -
3D Maps of Mineral Composition and Hydroxyapatite Orientation in Fossil Bone Samples Obtained by X-ray Diffraction Computed Tomography
(Journal article; Peer reviewed, 2018)Whether hydroxyapatite (HA) orientation in fossilised bone samples can be non-destructively retrieved and used to determine the arrangement of the bone matrix and the location of muscle attachments (entheses), is a question ... -
3ΛH and -3Λ-H production in Pb-Pb collisions at √sNN=2.76 TeV
(Journal article; Peer reviewed, 2016)The production of the hypertriton nuclei 3_Hand 3¯_Hhas been measured for the first time in Pb–Pbcollisions at √sNN=2.76TeVwith the ALICE experiment at LHC. The pT-integrated 3_Hyield in one unity of rapidity, dN/dy ×B.R. ... -
3Λh and 3‾Λ‾h lifetime measurement in Pb–Pb collisions at √sNN = 5.02 TeV via two-body decay
(Journal article; Peer reviewed, 2019)An improved value for the lifetime of the (anti-)hypertriton has been obtained using the data sample of Pb–Pb collisions at TeV collected by the ALICE experiment at the LHC. The (anti-)hypertriton has been reconstructed ... -
A "clearcut" case? Brown bear selection of coarse woody debris and carpenter ants on clearcuts
(Journal article; Peer reviewed, 2015-07-05)Forest management alters habitat characteristics, resulting in various effects among and within species. It is crucial to understand how habitat alteration through forest management (e.g. clearcutting) affects animal ... -
A capacitive touch screen sensor for detection of urinary tract infections in portable biomedical devices
(Journal article; Peer reviewed, 2014)Incidence of urinary tract infections (UTIs) is the second highest among all infections; thus, there is a high demand for bacteriuria detection. Escherichia coli are the main cause of UTIs, with microscopy methods and urine ... -
A Clover shaped silicon piezoresistive microphone for miniaturized photoacoustic gas sensors
(Chapter, 2009)Here we present the design and modeling of a novel piezoresistive microphone designed for a photoacoustic gas sensor system. The microphone is fabricated using a novel process to enable DRIE etch through of membranes of ... -
A comparative study between electrical capacitance tomography and time-resolved X-ray tomography
(Journal article; Peer reviewed, 2013)Modern day tomographs enable the research community to investigate the internal flow behaviour of a fluidized bed by non invasive methods that partially overcome the opaque nature of a dense bubbling bed. Each tomographic ... -
A comparison between a two feedback control loop and a reinforcement learning algorithm for compliant low-cost series elastic actuators
(Chapter, 2020)Highly-compliant elastic actuators have become progressively prominent over the last years for a variety of robotic applications. With remarkable shock tolerance, elastic actuators are appropriate for robots operating in ... -
A didactically motivated PLS prediction algorithm
(Journal article; Peer reviewed, 2001)The intention of this paper is to develop an easily understood PLS prediction algorithm, especially for the control community. The algorithm is based on an explicit latent variables model, and is otherwise a combination ... -
A gross assessment of the suitability of selected Scottish riparian habitats for beaver
(Journal article; Peer reviewed, 2000)In November 1998 we were shown a selection of riparian habitats in Scotland and asked to assess their suitability for beaver based on our experience in working with beaver elsewhere. Though many examples of good beaver ... -
A human-induced landscape of fear influences foraging behavior of brown bears
(Journal article; Peer reviewed, 2018)Animals adapt their foraging behavior to variations in food availability and predation risk. In Sweden, brown bears (Ursus arctos) depend on a nearly continuous intake of berries, especially bilberries (Vaccinium myrtillus) ... -
A Mathematical Theory for Mixing of Particulate Materials
(Doctoral thesis, 2006)A theoretical framework for sampling theory is developed. In this relation, concepts like mixture heterogeneity and representative samples are mathematically defined. Further, the relation between Gy's concepts of accuracy ... -
A microfluidic device for continuous sensing of systemic acute toxicants in drinking water
(Journal article; Peer reviewed, 2013)A bioluminescent-cell-based microfluidic device for sensing toxicants in drinking water was designed and fabricated. The system employed Vibrio fischeri cells as broad-spectrum sensors to monitor potential systemic cell ... -
A nearest integer solution to the longest run of randomly generated words
(Journal article; Peer reviewed, 2012)How rare is the event of observing more than a certain number of consecutive and identical letters of any kind somewhere in a randomly generated word? No one can deny that the use of generating functions is crucial for ... -
