TANdoRI Data Management Plan

The overriding principle of the guidance provided by the RCUK Common Principles on Data Policy is that research data produced using public funds is in the common public good and should be made openly available in a timely manner; access should be available with as few restrictions as possible. With this as a central guiding principle, a data management plan is set out below. Best practices are set out by the UK’s Digital Curation Centre; this is a “world-leading centre of expertise in digital information curation with a focus on building capacity, capability and skills for research data management across the UK's higher education research community.” Ultimately data will be published in appropriate scientific journals that permit free and open access to the general public; this is compliance with RCUK’s requirements all partners involved in the project (including Rensselaer Polytechnic Institute) will agree to comply with common practices of data management, storage and management, as outlined in this document

The nature of internal representation in the internal lexicon

The first two experiments reported were concerned with the fact and growth of visual and acoustic representations of simple words in the Mental Lexicon. Using a Learning paradigm it was established that some form of visual and acoustic representations are formed within three exposures and that these forms of a word are also a basis for lexical organization. Five experiments, employing different techniques, were aimed at testing the psychological reality of the morphemic structure of prefixed words. It was established that the morphemic structure of some of these words is represented; that the identity of some prefixes is represented; and that some non-specific knowledge concerning the relationship between orthographic and prefix structure is also represented. Finally, the spelling errors of 11 year old children were analysed. This analysis revealed that acoustic, visual (more properly graphemic), and morphemic information, as well as some knowledge of phonotactic rules and statistical regularities, are represented in the Internal Lexicon. It is concluded that the contents of the Internal lexicon are both redundant and heterogeneous.

Modelling Transient Winds

This paper examines the flow field associated with a variety of transient winds and discussed in detail the physical and numerical simulation of a flow structure that could be interpreted as a thunderstorm downburst. The possible pressure field arising from such a structure as it impacts on a high-rise building is examined. Possible differences between such flow phenomena and those corresponding to typical boundary layer winds are observed to occur – the magnitude and importance of these differences currently remains an open point.Laboratorio de Capa Límite y Fluidodinámica AmbientalGrupo Fluidodinámica Computaciona

Experimental investigation of the slipstream development around a container freight train using a moving model facility

AbstractIncreases in the volume of trade within the UK rail freight industry have led to proposed increases in freight train speeds. There is a concern that the unsteady slipstream created around a moving freight train could have implications on efficiency and the safety of passengers waiting on platforms or trackside workers. This paper describes a series of moving model-scale experiments conducted at the University of Birmingham’s TRAIN rig facility. Experiments were undertaken to assess the slipstream development of a container freight train and draw conclusions on flow characteristics. In this paper the term ‘freight train’ refers to a series of flatbed wagons loaded with ISO standard shipping containers hauled by a Class 66 locomotive. In-depth analysis of slipstream velocity and static pressure ensemble average results at train side and above the roof identified a series of key flow regions. Results within the boundary layer region exhibit an influence from container loading configuration. Slipstream magnitudes are larger than typical high speed passenger train results, which it is suggested is related to the vehicle shape. The effect of train length and train speed was also considered. A detailed analysis of the nature of slipstream velocity components in specific flow regions is investigated, and conclusions drawn on characteristic patterns and factors influencing possible safety issues. The analysis highlighted differences created through decreased container loading efficiencies, creating increased boundary layer growth with a larger displacement thickness with higher turbulence intensities. Integral time and length scales calculated through autocorrelation indicate that proposed limits of human instability are exceeded for the container freight train with a lower loading efficiency. Overall the results from this paper offer for the first time a definitive experimental study on container freight slipstream characteristics, allowing the nature of the flow field around freight trains to be understood in far greater detail than before

Nucleosynthesis Predictions for Intermediate-Mass AGB Stars: Comparison to Observations of Type I Planetary Nebulae

Type I planetary nebulae (PNe) have high He/H and N/O ratios and are thought to be descendants of stars with initial masses of ~3-8Msun. These characteristics indicate that the progenitor stars experienced proton-capture nucleosynthesis at the base of the convective envelope, in addition to the slow neutron capture process operating in the He-shell (the s-process). We compare the predicted abundances of elements up to Sr from models of intermediate-mass asymptotic giant branch (AGB) stars to measured abundances in Type I PNe. In particular, we compare predictions and observations for the light trans-iron elements Se and Kr, in order to constrain convective mixing and the s-process in these stars. A partial mixing zone is included in selected models to explore the effect of a 13C pocket on the s-process yields. The solar-metallicity models produce enrichments of [(Se, Kr)/Fe] < 0.6, consistent with Galactic Type I PNe where the observed enhancements are typically < 0.3 dex, while lower metallicity models predict larger enrichments of C, N, Se, and Kr. O destruction occurs in the most massive models but it is not efficient enough to account for the > 0.3 dex O depletions observed in some Type I PNe. It is not possible to reach firm conclusions regarding the neutron source operating in massive AGB stars from Se and Kr abundances in Type I PNe; abundances for more s-process elements may help to distinguish between the two neutron sources. We predict that only the most massive models would evolve into Type I PNe, indicating that extra-mixing processes are active in lower-mass stars (3-4Msun), if these stars are to evolve into Type I PNe.Comment: 39 pages, accepted for publication in Ap
