Analysis of Runge-Kutta methods using Butcher tableaus
No full textThis Bachelor thesis provides an analysis of Runge-Kutta methods using Butcher tableaus. Runge-Kutta method are numerical methods used for approximating initial value problems. A Runge-Kutta method can be classified as either an explicit or an implicit method. A special kind of implicit methods are diagonally implicit methods. The type of method can be recognised by the Butcher tableau. Using the entries of the Butcher tableau, one can compute the amplification factor of a Runge-Kutta method. The amplification factor can then be used to compute the order of the local truncation error and the stability region. Examples of these computations are given for seven methods. Furthermore, this thesis provides an algorithm to perform time steps for each of the three types of Runge-Kutta methods. Finally, in order to analyse the global truncation error of the seven methods, the algorithm to perform time steps is used with different step sizes.Applied Mathematic

Water ice at mid-latitudes on Mars
No full textMars’s mid-latitudes, corresponding approximately to the 30°–60° latitude bands in both hemispheres, host abundant water ice in the subsurface. Ice is unstable with respect to sublimation at Mars’s surface beyond the polar regions, but can be preserved in the subsurface at mid-to-high latitudes beneath a centimeters-to-meters-thick covering of lithic material. In Mars’s mid-latitudes, water ice is present as pore ice between grains of the martian soil (termed “regolith”) and as deposits of excess ice exceeding the pore volume of the regolith. Excess ice is present as lenses within the regolith, as extensive layers tens to hundreds of meters thick, and as debris-covered glaciers with evidence of past flow. Subsurface water ice on Mars has been inferred indirectly using numerous techniques including numerical modeling, observations of surface geomorphology, and thermal, spectral, and ground-penetrating radar analyses. Ice exposures have also been imaged directly by orbital and landed missions to Mars. Shallow pore ice can be explained by the diffusion and freezing of atmospheric water vapor into the regolith. The majority of known excess ice deposits in Mars’s mid-latitudes are, however, better explained by deposition from the atmosphere (e.g., via snowfall) under climatic conditions different from the present day. They are thought to have been emplaced within the last few million to 1 billion years, during large-scale mobilization of Mars’s water inventory between the poles, equator, and mid-latitude regions under cyclical climate changes. Thus, water ice deposits in Mars’s mid-latitudes probably host a rich record of geologically recent climate changes on Mars. Mid-latitude ice deposits are leading candidate targets for in situ resource utilization of water ice by future human missions to Mars, which may be able to sample the deposits to access such climate records. In situ water resources will be required for rocket fuel production, surface operations, and life support systems. Thus, it is essential that the nature and distribution of mid-latitude ice deposits on Mars are characterized in detail
Harvey Butcher : a passion for astronomical instrumentation
No full textAbstract: This paper covers some aspects of the scientific life of Harvey Butcher who was the Director of the Research School for Astronomy and Astrophysics at the Australian National University in Canberra from September 2007 to January 2013. He has made significant contributions to research on the evolution of galaxies, nucleo-synthesis, and on the design and implementation of advanced astronomical instrumentation including LOFAR (Low Frequency Array Radio telescope). He is well known for his discovery of the Butcher-Oemler effect. Before coming to Australia he was the Director of the Netherlands Foundation for Research in Astronomy from September 1991 to January 2007. In 2005 he was awarded a Knighthood in the Order of the Netherlands Lion for contributions to interdisciplinary science, innovation and public outreach. This paper is based on an interview conducted by the author with Harvey Butcher for the National Project on Significant Australian Astronomers sponsored by the National Library of Australia. Except otherwise stated, all quotations used in this paper are from the Butcher interview which has been deposited in the Oral History Archives of the National Library
<strong>HiRISE digital terrain model (1 m/pixel) and orthorectified image (25 cm/pixel) of a viscous flow feature incised by a gully in Nereidum Montes, Mars.</strong>
No full textHigh Resolution Imaging Science Experiment (HiRISE) digital terrain model (DTM) and orthorectified image of a viscous flow feature incised by a gully in Nereidum Montes, Mars.
These data products were produced by Joel Davis at the Natural History Museum, London, and re-projected by Frances Butcher at the University of Sheffield for the purposes of the study presented in:
Butcher, F.E.G., Arnold, N.S., Conway, S.J., Berman, D.C., Davis, J.M., and Balme, M.R. 2023, The Internal Structure of a Debris-Covered Glacier on Mars Revealed by Gully Incision, Icarus, https://doi.org/10.1016/j.icarus.2023.115717.
Please read the following information carefully.
Data Sets
The following files are present in .tif format. These are geotiffs and have geospatial metadata:
- 1 m/pixel DTM: ‘NWArgyre_1_AATE_1m_Sinusoidal.tif’
- 1 m/pixel FOM (Figure of Merit - see Readme.txt): ‘FOM_NWArgyre_1_AATE_1m_Sinusoidal.tif’
- 25 cm/pixel orthoimage: ‘ESP_051036_1370_25o_Sinusoidal.tif’
- Readme.txt:Contains further information, including an explanation of the values in the Figure of Merit
The DTM was generated using BAE Systems SOCET SET software, with the following HiRISE images as input:
-ESP_051036_1370: https://www.uahirise.org/ESP_051036_1370
-ESP_015947_1370: https://www.uahirise.org/ESP_015947_1370
The orthoimage was generated by orthorectifying HiRISE image ESP_051036_1370 using the DTM.
The DTM, FOM, and orthoimage were re-projected in ESRI ArcGIS 10.7 to minimise the effects of distortion upon the measurements and modelling results presented in Butcher et al. (2023). The sinusoidal projection used has a central meridian of 308.75°E, and is based on the IAU spherical datum for Mars (radius 3396190 m).
The data are not georeferenced to any other dataset in this release. Therefore care should be taken in the first instance, with georeferencing as required. The overall quality of the DTM is good, but noise levels vary – check the FOM (see below) and create a shaded relief map to ensure the DTM is adequate for your required use.
We note that since we generated the DTM and orthoimage, the HiRISE team also released a DTM generated from the same images, including additional colour orthorectified images (which are used in Butcher et al. 2023). These independently-generated data can be found at: https://www.uahirise.org/dtm/ESP_015947_1370
DTM Vertical Precision
The vertical precision of the DTM was estimated by Butcher et al. (2023) to be 0.2 m (based on a stereo convergence angle between input images of 14.8°, and assuming an RMS pixel matching error of 0.2 pixels) following the approach of:
- Kirk, R. L., et al. (2008), Ultrahigh resolution topographic mapping of Mars with MRO HiRISE stereo images: Meter-scale slopes of candidate Phoenix landing sites, J. Geophys. Res., 113, E00A24, doi:10.1029/2007JE003000.

Satire and Trauma in Patrick McCabe’s <em>The Butcher Boy</em>
No full textThe Butcher Boy (1992) is the third novel by Northern Irish author Patrick McCabe. It tells the story of 12-year-old Francie Brady and is set in the small town of Clones, in western County Monaghan, Ireland in the early 1960s. The town was badly hit economically by the partition of Ireland in 1921 because of its location on the border with County Fermanagh in Northern Ireland. The Butcher Boy emphasises the significant influence the instability of the community during the 1960s, a time of rapid change and ethnic and political violence, has on this dysfunctional Brady family. These political and economic circumstances are very relevant for our discussion because the Bradys, as part of this small community, suffer from some post-traumatic consequences derived from these circumstances, which affect their psychological state and identity in very negative terms. This paper focuses on how McCabe recreates Francie’s post-traumatic effects of such a difficult childhood and upbringing through formal literary devices characteristic of both trauma fiction and satire rhetoric, and to what effect the Irish writer uses them
