Estimating size in incremental software development projects
(2005-12)The motivation for this work is derived from the current interest in speeding up development schedules. A key implication of the shift to more rapid development methods is the growing emphasis on fixed time and fixed effort ... -
Estimating sizes of faint, distant galaxies in the submillimetre regime
(2016-10-21)We measure the sizes of redshift ˜2 star-forming galaxies by stacking data from the Atacama Large Millimeter/submillimeter Array (ALMA). We use a uv-stacking algorithm in combination with model fitting in the uv-domain and ... -
Estimating the diffusive heat flux across a stable interface forced by convective motions
(2010)Entrainment at the top of the convectively-driven boundary layer (CBL) is revisited using data from a high-resolution large-eddy simulation (LES). In the range of values of the bulk Richardson number RiB studied here (about ... -
Estimating the low-mass IMF in OB associations : o Orionis
(Springer Nature, 2005)We investigate the issues of contamination and exclusion in photometric membership selection techniques when applied to OB associations. We use radial velocities to calculate membership probabilities for a sample of very ... -
Estimating the Number of Local Maxima for k-SAT Instances
(2008)We explore the applicability of a sampling method devised by J. Garnier and L. Kallel (SIAM J. Discrete Math., 2002) to approximate the number of local maxima in search spaces induced by k-SAT instances and a simple ... -
Estimating the star formation rate at 1 kpc scales in nearby galaxies.
(2012-07)Using combinations of H alpha, ultraviolet (UV), and infrared (IR) emission, we estimate the star formation rate (SFR) surface density, Sigma(SFR), at 1 kpc resolution for 30 disk galaxies that are targets of the IRAM ... -
Estimating under-reporting of energy intake in dietary surveys using an individualised method
(2007)Under-reporting (UR) of energy intake (EI) by self-reported dietary methods is well-documented but the methods used to estimate UR in population-based studies commonly assume a sedentary lifestyle. We compared estimated ... -
Estimating Willingness to Pay Air Passenger Duty
(2018-09-01)Carbon taxation on air travellers is widely considered an effective way of offsetting environmental externalities and adjusting tourist flow. Despite the popularity of carbon taxation, research investigating travellers’ ... -
Estimation and Comparison of Endogenous Ordered Category Multilevel Models
(University of Hertfordshire, 2004)Data often take the form of ordered categories. For instance, in education, test results are often reported as grades. Where a hierarchical structure exists for--the data, multilevel modelling of such ordered categorisations ... -
Estimation and comparison of endogenous ordered category multilevel models

Estimation and Modelling of Errors in the Library Preparation Stage of Next Generation Sequencing
(2020-12-16)Next-generation sequencing has empowered genomics by making it possible to sequence genomes at a lower cost and less time compared to the traditional Sanger method. However, these improvements suffer from reduced accuracy ... -
The estimation of body height from ulna length in healthy adults from different ethnic groups
(2012)Background: Assessments of nutritional status frequently incorporate a measure of height to evaluate a person’s relative thinness or fatness. Because height is often difficult to quantify, it may be predicted from alternative ... -
Estimation of energy expenditure using prediction equations in overweight and obese adults : a systematic review
(2016-08-01)Background: Estimates of energy requirements are needed in weight management and are usually determined using prediction equations. The objective of these two systematic reviews was to identify which equations based on ... -
Estimation of error in bankfull width comparisons from temporally sequenced raw and corrected aerial photographs
(2003)This study investigates the propagation of error through image-to-image comparison of 285 river bankfull width measurements of the Afon Trannon, mid-Wales. Bankfull width is quantified from both aerial photographs analysed ... -
Estimation of microphysical parameters of atmospheric pollution using machine learning
(Springer Nature, 2018-09-27)The estimation of microphysical parameters of pollution (effective radius and complex refractive index) from optical aerosol parameters entails a complex problem. In previous work based on machine learning techniques, ... -
Estimation of radiative forcing by the dust and non-dust content in mixed East Asian pollution plumes on the basis of depolarization ratios measured with lidar
(2012-12)The contribution of dust and non-dust aerosols to the lidar observed total backscattering was estimated from the linear particle depolarization ratios (delta(p)) under the assumption of externally mixed aerosols. During ... -
Estimation of Stability and Control Derivatives for a Piper Cub J-3 Remotely Piloted Vehicle
(2012-08-01)The aerodynamic stability and control derivatives for a scaled Piper Cub J-3 remotely piloted aircraft are estimated here, principally using the Engineering Sciences Data Unit (ESDU) data items. These modern semi-empirical ... -
Estimation of Stellar Metal Abundance. II : A Recalibration of the Ca II K Technique, and the Autocorrelation Function Method
(1999)We have recalibrated a method for the estimation of stellar metal abundance, parameterized as [Fe/H], based on medium-resolution (1–2 Å) optical spectra (the majority of which cover the wavelength range 3700–4500 Å). The ... -
Estimation of the Microbiological Quality of Meat using Rapid and Non-Invasive Spectroscopic Sensors
(2020-06-08)Spectroscopic methods in tandem with machine learning methodologies have attracted considerable research interest for the estimation of food quality. The objective of this study was the evaluation of Fourier transform ...
