Item-by-item sampling for promotional purposes
(University of Hertfordshire, 2012)In this paper we present a method for sampling items that are checked on a pass/fail basis, with a view to a claim being made about the success/failure rate for the purposes of promoting a company’s product/service. Attention ... -
The Iterative Development of the Humanoid Robot Kaspar: An Assistive Robot for Children with Autism
(2017-11)This paper gives an overview of the design and development of the humanoid robot Kaspar. Since the first Kaspar robot was developed in 2005, the robotic platform has undergone continuous development driven by the needs of ... -
Iterative Robust Semi-Supervised Missing Data Imputation
(2020-05-12)In many real-world applications scientists are often confronted with the problem of incomplete datasets due to several reasons. The direct analysis of datasets with missing values in attributes inevitably results in ... -
‘It’s not in my job description’: An exploration of trainee clinical psychologists’ attitudes towards research and perceptions of DClinPsy research culture
(2023-07)This project aimed to investigate attitudes towards research and perceived research culture among trainee clinicalpsychologists across the UK. This was achieved by exploring factors such as: research training environment,research ... -
“I’m not nervous. It’s just how I talk”: Stammering in University and the creation of an inclusive learning environment
(2020-05)It is estimated that over 23,000 students in UK Higher Education have a stammer. Yet, Universities are consistently failing to support students with communication impairments. Recent research has revealed how students who ... -
J-band variability of M dwarfs in the WFCAM Transit Survey
(2012-12)We present an analysis of the photometric variability of M dwarfs in the Wide Field Camera (WFCAM) Transit Survey. Although periodic light-curve variability in low mass stars is generally dominated by photospheric star ... -
Jacobites and Jacobins : Two Eighteenth Century Perspectives
(Record Society of Lancashire and Cheshire, 2006)The Memoir of Walter Shairp: The Story of the Liverpool Regiment During the Jacobite Rebellion of 1745; and the Writings of the Cragg Family of Wyresdale -
JADES Imaging of GN-z11: Revealing the Morphology and Environment of a Luminous Galaxy 430 Myr after the Big Bang
(2023-07-20)We present JWST NIRCam nine-band near-infrared imaging of the luminous z = 10.6 galaxy GN-z11 from the JWST Advanced Deep Extragalactic Survey of the GOODS-N field. We find a spectral energy distribution (SED) entirely ... -
JADES Initial Data Release for the Hubble Ultra Deep Field: Revealing the Faint Infrared Sky with Deep JWST NIRCam Imaging
(2023-11-01)JWST has revolutionized the field of extragalactic astronomy with its sensitive and high-resolution infrared view of the distant Universe. Adding to the new legacy of JWST observations, we present the first NIRCam imaging ... -
JADES NIRSpec Spectroscopy of GN-z11: Lyman-$α$ emission and possible enhanced nitrogen abundance in a $z=10.60$ luminous galaxy
(2023-09-11)We present JADES JWST/NIRSpec spectroscopy of GN-z11, the most luminous candidate z>10 Lyman break galaxy in the GOODS-North field with MUV =-21.5. We derive a redshift of z = 10.603 (lower than previous determinations) ... -
JADES: Detecting [OIII]$λ4363$ Emitters and Testing Strong Line Calibrations in the High-$z$ Universe with Ultra-deep JWST/NIRSpec Spectroscopy up to $z \sim 9.5$
(2024-02-02)We present ten novel [OIII]λ4363 auroral line detections up to z ∼ 9.5 measured from ultra-deep JWST/NIRSpec MSA spectroscopy from the JWST Advanced Deep Extragalactic Survey (JADES). We leverage the deepest spectroscopic ... -
Jades: Discovery of extremely high equivalent width Lyman- α emission from a faint galaxy within an ionized bubble at z = 7.3
(2023-10-05)We report the discovery of a remarkable Lyα emitting galaxy at z = 7.2782, JADES-GS+53.16746-27.7720 (shortened to JADES-GS-z7-LA), with rest-frame equivalent width, EW 0(Lyα) = 388.0 ± 88.8 Å and UV magnitude -17.0. The ... -
JADES: Insights into the low-mass end of the mass–metallicity–SFR relation at 3 < z < 10 from deep JWST/NIRSpec spectroscopy⋆
(2024-04-10)We analysed the gas-phase metallicity properties of a sample of low-stellar-mass (log M⋆/M⊙ ≲ 9) galaxies at 3 < z < 10 observed with JWST/NIRSpec as part of the JADES programme in its deep GOODS-S tier. By combining this ... -
