Calculation of the interface curvature and normal vector with the level-set method
(Journal article, 2013)This article addresses the use of the level-set method for capturing the interface between two fluids. One of the advantages of the level-set method is that the curvature and the normal vector of the interface can be readily ... -
A calculator for local peatland volume and carbon stock to support area planners and decision makers
(Peer reviewed; Journal article, 2023)Conserving soil carbon is one of many actions to take in limiting global warming. However, carbon dense peatlands are still being drained or excavated. Infrastructure development is one of the major current threats to boral ... -
Calf Raise Exercise Training Increases Walking Performance in Patients With Intermittent Claudication
(Journal article; Peer reviewed, 2017)BACKGROUND: Symptoms of intermittent claudication (IC) are improved by exercise. The improvement might be secondary to increased blood perfusion or increased muscle mitochondrial capacity. Ischemia followed by reperfusion, ... -
Calibrating and adjusting expectations in life: A grounded theory on how elderly persons with somatic health problems maintain control and balance in life and optimize well-being
(Journal article; Peer reviewed, 2011)Aim: This study aims at exploring the main concern for elderly individuals with somatic health problems and what they do to manage this. Method: In total, 14 individuals (mean = 74.2 years; range = 68–86 years) of both ... -
Calibrating range measurements of lidars using fixed landmarks in unknown positions
(Peer reviewed; Journal article, 2021)We consider the problem of calibrating range measurements of a Light Detection and Ranging (lidar) sensor that is dealing with the sensor nonlinearity and heteroskedastic, range-dependent, measurement error. We solved the ... -

(Journal article; Peer reviewed, 2020)We consider the problem of calibrating range measurements of a Light Detection and Ranging (lidar) sensor that is dealing with the sensor nonlinearity and heteroskedastic, range-dependent, measurement error. We solved the ... -
The calibration challenge when inferring longitudinal track profile from the inertial response of an in-service train
(Peer reviewed; Journal article, 2021)An Irish Rail intercity train was instrumented for a period of one month with inertial sensors. In this paper, a novel calibration algorithm is proposed to determine, with reasonable accuracy, vehicle model parameters from ... -
Calibration Method for monitoring hygro-mechanical reactions of coated and uncoated pine and oak wood by Acoustic Emission Non-Destructive Testing
(Peer reviewed; Journal article, 2020)The main issue of wood is its sensitivity to Relative Humidity (RH) variations, affecting its dimensional stability, and thus leading to crack formations and propagations. In situ structural health monitoring campaigns ... -
Calibration of Acoustic Emission parameters in relation to the equilibrium moisture content variations in a Pinus sylvestris beam
(Peer reviewed; Journal article, 2021)Under constant temperature conditions, air relative humidity variations affect hygroscopic objects, such as wood, modifying their moisture content and provoking, at low values, damages and fractures. The parameters (amplitude, ... -
Calibration of DSF model for real-time control
(Peer reviewed; Journal article, 2021)Double Skin Façades are complex fenestration systems capable to control solar heat gain and ventilation in buildings. Due to the high flexibility of such innovative components, having energy models able to replicate the ... -
Calibration of Horizontal Acoustic Doppler Current Profiler by three dimensional CFD simulations
(Journal article; Peer reviewed, 2015)This study presents a calibration method of horizontal acoustic Doppler current profilers (H-ADCP), based on 3D Computational Fluid Dynamics (CFD) simulations. Rigidly mounted H-ACCPs are currently used to continuously ... -
Calibration of material models against TSTM test for crack risk assessment of early-age concrete containing fly ash
(Journal article; Peer reviewed, 2018)Making reliable cracking risk assessment involves experimental testing and advanced modeling of the time- and temperature-dependent behavior of the properties, the restraint conditions of the structure, and the external ... -
Calibration of simplified safety formats for structural timber design
(Journal article; Peer reviewed, 2017)A framework for calibrating the reliability elements in simplified semi-probabilistic design safety formats is presented. The objective of calibration is to minimize the increase of construction costs, compared to the ... -
Calibration of strain gauges on a model runner blade combining numerical and experimental data
(Peer reviewed; Journal article, 2023)In this paper, we present the calibration setup, method, and results for a set of strain gauges installed on the trailing edge of the runner blades of a model Francis turbine. The calibration work is done as a step in the ... -
Calibration of the modified Mohr-Coulomb fracture model by use of localization analyses for three tempers of an AA6016 aluminium alloy
