Atmospheric Radiation And Tgfs: Unexplained Radiation In Our Skies, Adrian Gallegos
Atmospheric Radiation And Tgfs: Unexplained Radiation In Our Skies, Adrian Gallegos
Honors College Research
There is a significant correlation between atmospheric electrification via thunderstorms and the occurrence of large emissions of x-ray and gamma ray radiation known as Terrestrial Gamma Ray Flashes (TGFs). Some physical phenomenon may be explained by either the RREA or Thermal Runaway models, but the scientific community as a whole is still largely at work on the theoretical frameworks.

Many websites are adapting their content for users who are accessing the Web using smartphones and tablets. The growth of this Mobile Web has required web archivists to change their practices in order to collect this ephemeral web content. We have created a tool called MobileFinder which can be used to automatically detect mobile pages when given the URL of a desktop web page. We used this tool in an experiment to gauge what techniques popular websites are currently using to expose mobile content, and we incorporated the tool into Heritrix to demonstrate its usefulness to the web archiving community.

This article discusses the challenges and solutions discovered for implementing the Memento protocol in a variety of browser environments. It describes the design and deployment of the client technologies which have been developed: a web application that functioned as a browser, an add-on for FireFox called MementoFox, a plugin for Internet Explorer and an Android-based client application. The design and technical solutions identified during the development will be of interest to those considering implementation of a Memento based platform, especially on the client side, however the interactions are also important for building conformant server-side systems.

Information about several topics discussed at the First International Workshop on Innovation in Digital Preservation (InDP 2009) on June 19, 2009 in Austin, Texas is presented. Topics include the collection of digital objects, web pages transition, and digital preservation (DP). The workshop featured presenters Rudolf Mayer, Martin Klein and Dominick Heutelbeck.

We describe the observed crawling patterns of various search engines (including Google, Yahoo and MSN) as they traverse a series of web subsites whose contents decay at predetermined rates. We plot the progress of the crawlers through the subsites, and their behaviors regarding the various file types included in the web subsites. We chose decaying subsites because we were originally interested in tracking the implication of using search engine caches for digital preservation. However, some of the crawling behaviors themselves proved to be interesting and have implications on using a search engine as an interface to a digital library.
