      Khalil, Ashraf; Connelly, Kay (Citeseer, 2004-01-05)
      With the increasing popularity of ubiquitous computing and context-aware services, the privacy challenges posed by such technologies remain one of the biggest concerns. Several research efforts have been aimed at better ...
    • On Negotiating Automatic Device Configuration in Smart Environments 

      Connell, Kay; Khalil, Ashraf (IEEE, 2004-03)
      It is desirable for mobile devices to automatically configure themselves based on the context of the environment and user preferences for both convenience and security purposes. Having the cell phone switch the ringer off ...
    • Context-Aware Configuration: A Study on Improving Cell Phone Awareness 

      Khalil, Ashraf; Connelly, Kay (Springer Berlin/Heidelberg, 2005-07-05)
      As the number of mobile devices we carry grows, the job of manag- ing those devices throughout the day becomes cumbersome. This is especially true for cell phones. Despite the many benefits they provide, cell phones create ...
    • Improving Cell Phone Awareness by Using Calendar Information 

      Khalil, Ashraf; Connelly, Kay (Springer, 2005-09)
      The many benefits that cell phones provide are at times overshadowed by the problems they create, as when one person’s cell phone disrupts a group activity, such as a class, meeting or movie. Cell phone interruption is ...
    • A novel structural-based approach to model the age hardening behaviour of aluminium alloys
