Data Visualization and R
No full textThis workshop focuses on principles and techniques for the visualization of data, with an equal emphasis on theory and implementation. Drawing on classic works by Cleveland (Visualizing Data), Tufte (The Visual Display of Quantitative Information), and Wilkinson (The Grammar of Graphics), a range of best practices for visualization are illustrated. Recently developed techniques for large-scale, 3D, and interactive visualization are also discussed. For each of these approaches, methods for creating similar graphics in the R open-source statistical language are demonstrated, using packages such as ggplot2, lattice, and others. Interactive visualization packages such as playwith, shiny and others are also explored.Presented at IASSIST 40th Annual Conference, "Aligning Data and Research Infrastructure", Toronto, Canada, June 3, 2014.Womack, Ryan (2014 June).

Survey report 2013/14 summer season Geoscience Australia, Author - Ryan Ruddick
No full textProgress Code: completedThis survey report describes surveys done by Ryan Ruddick of Geoscience Australia at Casey during the 2013/14 summer season. In addition to survey work for Geoscience Australia, Ryan also carried out some tasks for the Australian Antarctic Division. The latter included levelling to the reference mark of the tide gauges at the wharf, surveys of buildings new or modified since the last survey and a survey of the fire hydrants.<br/><br/>The survey report is yet to be completed.<br/>The Related URLs include links to where the following can be downloaded:<br/>1 Data from the surveys of the buildings and fire hydrants;<br/>2 GIS data representing features such as buildings at Casey. Data resulting from the 2013/14 survey has Dataset_id = 315 in the attribute table
Hands-on Big Data
No full textThis workshop is for those of you who, having read about Big Data and seen some of its results in academic studies and the commercial world, would like to get a sense of what actually working with Big Data entails.
The workshop will provide an overview of key technologies for the handling and analysis of large scale datasets, including Hadoop/MapReduce, the RHadoop package, other R packages used for large scale analysis, and Big Data handling environments such as Cloudera, Hortonworks, Tessera, and Amazon Web Services. We will also discuss a few of the primary challenges in successfully completing analysis of large scale data, such as integrating and structuring heterogenous data, handling sparse matrices, and devising effective analytical routines using parallel processing and splitting data. Participants will work with a live demonstration environment that provides a realistic introduction to Big Data Analytics using scripts that will run both on a scaled-down demonstration dataset and on truly large scale data.Presented at IASSIST 41st Annual Conference, "Bridging the Data Divide: Data in the International Context," Minneapolis, Minnesota, June 2, 2015

Quasi-cyclic Generalized LDPC codes with low error floors
No full textIn this paper, a novel methodology for designing structured generalized LDPC (G-LDPC) codes is presented. The proposed design results in quasi-cyclic G-LDPC codes for which efficient encoding is feasible through shift-register-based circuits. The structure imposed on the bipartite graphs, together with the choice of simple component codes, leads to a class of codes suitable for fast iterative decoding. A pragmatic approach to the construction of G-LDPC codes is proposed. The approach is based on the substitution of check nodes in the protograph of a low-density parity-check code with stronger nodes based, for instance, on Hamming codes. Such a design approach, which we call LDPC code doping, leads to low-rate quasi-cyclic G-LDPC codes with excellent performance in both the error floor and waterfall regions on the additive white Gaussian noise channel
