A focus on L dwarfs with trigonometric parallaxes
We report new parallax measurements for ten L and early T type dwarfs, five of which have no previous published values, using observations over 3 years at the robotic Liverpool Telescope. The resulting parallaxes and proper ...
280 one-opposition near-Earth asteroids recovered by the EURONEAR with the Isaac Newton Telescope
Context. One-opposition near-Earth asteroids (NEAs) are growing in number, and they must be recovered to prevent loss and mismatch risk, and to improve their orbits, as they are likely to be too faint for detection in ...
Applying machine learning methods for characterization of hexagonal prisms from their 2D scattering patterns – an investigation using modelled scattering data
Better understanding and characterization of cloud particles, whose properties and distributions affect climate and weather, are essential for the understanding of present climate and climate change. Since imaging cloud ...
First Steps in Bridging the Gap between the Virtual Learning Environment and Social Media : Students Attitudes
The eSCISM project aims to bridge the divide between a student’s academic community of practice and their existing social networks. While students are using social media amongst themselves, a divide remains between tutors’ ...
Photometric redshift estimation using Gaussian processes
We present a comparison between Gaussian processes (GPs) and artificial neural networks (ANNs) as methods for determining photometric redshifts for galaxies, given training-set data. In particular, we compare their degradation ...
Multiobjective Optimization Applied to the Eradication of Persistent Pathogens
In scenarios such as therapeutic modeling or pest control, one aims to suppress infective agents or maximize crop yields while minimizing the side-effects of interventions, such as cost, environmental impact, and toxicity. ...
Optimizing Preventive Maintenance Models
We deal with the problem of scheduling preventive maintenance (PM) for a system so that, over its operating life, we minimize a performance function which reflects repair and replacement costs as well as the costs of the ...
The Laplace transform dual reciprocity boundary element method for electromagnetic heating problems
(EC Ltd, 2005)
There are many situations in applied science and engineering where materials are heated electrically via the so-called ohmic heating, or Joule heating, process. In this process the heating occurs throughout the volume as ...
Evaluation of Logarithmic integrals in two dimensional boundary element computation
