      Zhao, Yuchen; Ye, Juan; Henderson, Tristan (ACM, 2016-03-07) - Conference item
      Location-sharing services such as Facebook and Foursquare/Swarm have become increasingly popular, due to the ease at which users can share their locations, and participate in services, games and other applications that ...
    • Fault detection for binary sensors in smart home environments 

      Ye, Juan; Stevenson, Graeme; Dobson, Simon (IEEE Computer Society, 2015-03-23) - Conference item
      Experiments in assisted living confirm that such systems can provide context-aware services that enable occupants to remain active and independent. They also demonstrate that abnormal sensor events hamper the correct ...
    • KCAR : a knowledge-driven approach for concurrent activity recognition 

      Ye, Juan; Stevenson, Graeme Turnbull; Dobson, Simon Andrew (2015-05) - Journal article
      Recognising human activities from sensors embedded in an environment or worn on bodies is an important and challenging research topic in pervasive computing. Existing work on activity recognition is mainly concerned with ...
    • LOC8 : A location model and extensible framework for programming with location 

      Stevenson, Graeme Turnbull; Ye, Juan; Dobson, Simon Andrew; Nixon, Paddy (2010) - Journal article
      Location is a core concept in most pervasive systems-and one that's surprisingly hard to deal with flexibly. Using a location model supporting a range of expressive representations for spaces, spatial relationships, and ...
    • Real-time emotion detection technologies for potential health applications 

      Ye, Juan; Morrell, Thomas; Murray, Lauren (2016-06-03) - Conference item
    • Recommending Location Privacy Preferences in Ubiquitous Computing 

      Zhao, Yuchen; Ye, Juan; Henderson, Tristan (2014-07-23) - Conference poster
      Location-Based Services have become increasingly popular due to the prevalence of smart devices. The protection of users’ location privacy in such systems is a vital issue. Conventional privacy protection methods such as ...
    • Recommending privacy preferences in location-sharing services 

      Zhao, Yuchen (University of St Andrews, 2017-06-21) - Thesis
      Location-sharing services have become increasingly popular with the proliferation of smartphones and online social networks. People share their locations with each other to record their daily lives or satisfy their social ...
    • A robust reputation-based location-privacy recommender system using opportunistic networks 

      Zhao, Yuchen; Ye, Juan; Henderson, Tristan (ACM, 2016-12-01) - Conference item
      Location-sharing services have grown in use commensurately with the increasing popularity of smart phones. As location data can be sensitive, it is important to preserve people’s privacy while using such services, and so ...
    • Self-management of self-organising mobile computing applications : a separation of concerns approach 

      Fernandez Marquez, Jose Luis; di Marzo Serugendo, Giovanna; Stevenson, Graeme Turnbull; Ye, Juan; Dobson, Simon Andrew; Zamonelli, Franco (ACM, 2014-03-24) - Conference item
