A spherical-plot solution to linking acceleration metrics with animal performance, state, behaviour and lifestyle
(Journal article; Peer reviewed, 2016)Background: We are increasingly using recording devices with multiple sensors operating at high frequencies to produce large volumes of data which are problematic to interpret. A particularly challenging example comes from ... -
A Study of Mass Transfer Kinetics of Carbon Dioxide in (Monoethanolamine + Water) by Stirred Cell
(Journal article; Peer reviewed, 2013-08-05)The gas phase resistance in a stirred cell was investigated to understand and avoid its influence on the measurement of the reaction kinetics. To validate the influence of gas phase resistance and the experimental conditions ... -
A Study of the Effect of Relative Permeability and Residual Oil Saturation on Oil Recovery
(Journal article; Peer reviewed, 2015-11-25)The depletion of oil production and the low recovery rate are the major challenges faced in oil production. Several studies have shown that considerable amount of oil still remains in the reservoir after the well shutdown. ... -
A test of the dear enemy phenomenon in the Eurasian beaver
(Journal article; Peer reviewed, 2002)We tested the hypothesis that Eurasian beavers, Castor fiber, display the dear enemy phenomenon; that is, they respond less aggressively to intrusions by their territorial neighbours than intrusions by nonterritorial ... -
A Variable Depth Search Algorithm for Binary Constraint Satisfaction Problems
(Journal article; Peer reviewed, 2015)The constraint satisfaction problem (CSP) is a popular used paradigm to model a wide spectrum of optimization problems in artificial intelligence. This paper presents a fast metaheuristic for solving binary constraint ... -
A Wearable Haptic System for the Health Monitoring of Elderly People in Smart Cities
(Journal article; Peer reviewed, 2018)A sensor-fusion wearable health-monitoring system with integrated haptic feedback was previously introduced by our research group. The system's components are the following: a chest-worn device with an embedded controller ... -
Abrupt high-latitude climate events and decoupled seasonal trends during the Eemian
(Journal article; Peer reviewed, 2018)The Eemian (the Last Interglacial; ca. 129–116 thousand years ago) presents a testbed for assessing environmental responses and climate feedbacks under warmer-than-present boundary conditions. However, climate syntheses ... -
Absorption and Desorption Study of Alkylamine Promoted DEEA Solvents for CO2 Capture
(Journal article; Peer reviewed, 2018)Three primary and two secondary mono-alkylamines, and a di-alkylamine (3-(Methylamino)propylamine, MAPA) were investigated in blend with a tertiary amine (2-(Diethylamino)ethanol, DEEA). The aim of the study was to ... -
Acoustic Characterization of Inhomogenous Layers using Finite Element Method
(Peer reviewed; Journal article, 2021)This study presents a finite element approach to estimate acoustic parameters of layers of arbitrary compositions using 2D and 3D models. In this approach the resonance frequency of a layer to be investigated is found by ... -
Acoustic chemometric prediction of total solids in bioslurry: A full-scale feasibility study for on-line biogas process monitoring
(Journal article; Peer reviewed, 2012)Dry matter is an important process control parameter in the bioconversion application field. Acoustic chemometrics, as a Process Analytical Technology (PAT) modality for quantitative characterisation of dry matter in complex ... -
Acoustic chemometrics for material composition quantification in pneumatic conveying - The critical role of representative reference sampling
(Journal article; Peer reviewed, 2012)Reliable monitoring of pneumatically conveyed particulate materials is critical for online detection and controlling material composition changes in the regimen of Process Analytical Technology (PAT), e.g. as the case ... -
Acoustic chemometrics for on-line monitoring and end-point determination of fluidised bed drying
(Journal article; Peer reviewed, 2013-07-02)An emerging process analytical technology (PAT) technique, acoustic chemometrics, was applied for monitoring of heated fluidised bed drying process. The feasibility of quantitative on-line monitoring of the drying progress ... -
Acoustic Impedance Matching of PMN-PT/epoxy 1-3 Composites for Underwater Transducers with Usable Bandwidth Restricted by Electrical Power Factor
(Peer reviewed; Journal article, 2019)Volume cost has limited the use of single crystals in underwater applications, butreported performance of PMN-PT sonar transducers now motivates the design of commercial prototypes. This work addresses optimization of the ... -
Adapting dynamic mathematical models to a pilot anaerobic digestion reactor
(Journal article; Peer reviewed, 2013)A dynamic model has been adapted to a pilot anaerobic reactor fed diarymanure. Both steady-state data from online sensors and laboratory analysis anddynamic operational data from online sensors are used in the model ... -
Addressing the hypertriton lifetime puzzle with ALICE at the LHC
(Journal article; Peer reviewed, 2019)The ALICE Collaboration collected a large data sample of Pb-Pb collisions at in 2015 at the Large Hadron Collider (LHC) and the excellent particle identification (PID) capabilities allow for the detection of rarely produced ... -
Aerobic and anaerobic speed predicts 800-m running performance in young recreational runners
(Peer reviewed; Journal article, 2021)The main aim was to investigate the impact of maximal aerobic speed (MAS), maximal anaerobic speed (MANS), and time to exhaustion (TTE) at 130% MAS, on 800-m running time performance (800TT). A second aim was to investigate ... -
Age-related changes in somatic condition and reproduction in the Eurasian beaver: Resource history influences onset of reproductive senescence
(Journal article; Peer reviewed, 2017)Using 15 years of data from a stable population of wild Eurasian beavers (Castor fiber), we examine how annual and lifetime access to food resources affect individual age-related changes in reproduction and somatic condition. ... -
Agreement between reconstructed and modeled boreal precipitation of the Last Interglacial
(Journal article; Peer reviewed, 2019)The last extended time period when climate may have been warmer than today was during the Last Interglacial (LIG; ca. 129 to 120 thousand years ago). However, a global view of LIG precipitation is lacking. Here, seven new ... -
Agricultural landscapes and the Loire River influence the genetic structure of the marbled newt in Western France
