  • The Bohemian Bookshelf : supporting serendipitous book discoveries through information visualization 

    Thudt, Alice; Hinrichs, Uta; Carpendale, Sheelagh (ACM Press - Association for Computing Machinery, 2012-05-05) - Conference item
    Serendipity, a trigger of exciting yet unexpected discoveries, is an important but comparatively neglected factor in information seeking, research, and ideation. We suggest that serendipity can be facilitated through ...
  • The Bohemian Bookshelf : supporting serendipitous discoveries through visualization 

    Thudt, Alice; Hinrichs, Uta; Carpendale, Sheelagh (University of Calgary, 2011) - Working or discussion paper
    Serendipity, a trigger of exciting discoveries when we least expect it, is currently being discussed as an often neglected but still important factor in information seeking processes, research, and ideation. In this paper ...
  • Bootstrapping opportunistic networks using social roles 

    Bigwood, Greg; Henderson, Tristan (IEEE, 2011-06-23) - Conference item
    Opportunistic routing protocols can enable message delivery in disconnected networks of mobile devices. To conserve energy in mobile environments, such routing protocols must minimise unnecessary message-forwarding. This ...
  • The broken dream of pervasive sentient ambient calm invisible ubiquitous computing 

    Aylett, Matthew P.; Quigley, Aaron John (ACM Press - Association for Computing Machinery, 2015-04-18) - Conference item
    We dreamt of technology becoming invisible, for our wants and needs to be primary and the tools we use for making them a reality to become like a genie, a snap of the fingers and ta daa, everything is realised. What went ...
  • BubbleType : enabling text entry within a walk-up tabletop installation 

    Hinrichs, Uta; Schmidt, Holly; Isenberg, Tobias; Hancock, Mark S.; Carpendale, Sheelagh (University of Calgary, 2008-02) - Working or discussion paper
    We address the issue of enabling text entry for walk-up-and-use interactive tabletop displays located in public spaces. Public tabletop installations are characterized by a diverse target user group, multiperson interaction, ...
  • Budget constrained execution of multiple Bag-of-Tasks applications on the Cloud 

    Thai, Long Thanh; Varghese, Blesson; Barker, Adam David (IEEE Computer Society, 2015-06-27) - Conference item
    Optimising the execution of Bag-of-Tasks (BoT) applications on the cloud is a hard problem due to the trade- offs between performance and monetary cost. The problem can be further complicated when multiple BoT applications ...
  • Cancer treatment and gonadal function : experimental and established strategies for fertility preservation in children and young adults
