    • Real-Time Communication in IEEE 802.11 Mobile Ad hoc Networks A Feasibility Study 

      CAHILL, VINNY; WEBER, STEFAN; GLEESON, MARK (2006)
      Achieving predictable communication latency in an ad hoc IEEE 802.11 wireless local area network necessitates an approach that overcomes the impact of the underlying non-deterministic contention-based medium access ...

    • Real-Time Display of Dublin Traffic Information on the Web 

      Dineen, Mark (Trinity College Dublin. Department of Computer Science, 2000-09)
      Many large-scale and highly specialised distributed systems such as Urban Traffic Control (UTC) systems produce considerable quantities of data on a real-time basis. This data is then frequently locked in a proprietary ...

    • Real-time Intrusion Detection for Ad hoc Networks 

      Stamouli, Ioanna (Trinity College Dublin. Department of Computer Science, 2003-09)
      In the recent years, wireless technology has enjoyed a tremendous rise in popularity and usage opening new fields of applications in the domain of networking. One such field concerns mobile ad hoc networks (MANETs) where ...

    • Removing Epistemological Bias From Empirical Observation of Neural Networks 

      Waldron, Ronan (Trinity College Dublin, Department of Computer Science, 1994-05-25)
      This paper addresses the application of neural network research to a theory of autonomous systems. Neural networks, while enjoying considerable success in autonomous systems applications, have failed to provide a firm ...

    • Representing Cases for CBR in XML 

      Coyle, Lorcan; Hayes, Conor; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 2002-11)
      Case Based Reasoning has found increasing application on the Internet as a shopping assistant for e-commerce stores. The strength of CBR in this area stems from its reuse of the knowledge base associated with a particular ...

    • Representing Similarity for CBR in XML 

      Coyle, Lorcan; Doyle, Donal; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 2004-07-26)
      As Case-Based Reasoning has matured as a discipline; the need for a standard means of representing case-based knowledge has come to the fore. While proposals exist for representing the vocabulary and the case-base ...

    • Research Directions for AI in Computer Games 

      Fairclough, Chris; Fagan, Michael; Mac Namee, Brian; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 2001-10)
      The computer games industry is now bigger than the film industry. Until recently, technology in games was driven by a desire to achieve real-time, photo-realistic graphics. To a large extent, this has now been achieved. ...

    • Retrieval Issues in Real-World CBR Applications How far can we go with discrimination-nets? 

      Cunningham, Padraig; Smyth, Barry; Finn, Donal; Cahill, Eamonn (Trinity College Dublin, Department of Computer Science, 1992-10)
      In this paper we present a proposition and ponder a question. We propose that a useful perspective on analogical reasoning and CBR is to consider them on a continuum of abstraction of remindings. This is an alternative ...

    • Retrieval Issues in Real-World CBR Applications How far can we go with discrimination-nets? 

      Cunningham, Padraig; Smyth, Barry; Finn, Donal; Cahill, Eamonn (Trinity College Dublin, Department of Computer Science, 1993-06)
      We propose that analogical reasoning and case based reasoning (CBR) tasks can be usefully characterised as a continuum reflecting the remoteness of the remindings involved. Remindings in CBR are generally between semantically ...

    • Retrieving Reusable Design Cases: Exploiting Adaptation Knowledge in Design Reuse 

      Smyth, Barry; Keane, Mark T. (Trinity College Dublin, Department of Computer Science, 1994-11)
      Case-based reasoning has been identified as a potentially fruitful candidate technology with which to investigate the development of automated design systems. Two critical stages in case-based design are design retrieval ...

    • A Review of Active Learning and Co-Training in Text Classification 

      Davy, Michael (Trinity College Dublin, Department of Computer Science, 2005-11-04)

    • A Review of Explanation and Explanation in Case-Based Reasoning 

      Doyle, Donal; Tsymbal, Alexey; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 2003)

    • A Review of the Resource Management Task in ATM Networks 

      Naughton, Shane (Trinity College Dublin, Department of Computer Science, 1995-04)
      [Introduction] An ATM network is a connection-oriented, packet-switched network with the ability to transport heterogeneous services irrespective of characteristics across the same underlying physical network. ATM networks ...

    • Risk Probability Estimating Based on Clustering 

      Chen, Yong; Jensen, Christian D.; Gray, Elizabeth; Seigneur, Jean-Marc (Trinity College Dublin, Department of Computer Science, 2003-05-21)
      Ubiquitous computing environments are highly dynamic, with new unforeseen circumstances and constantly changing environments, which introduces new risks that cannot be assessed through traditional means of risk analysis. ...

    • The Role of Identity in Pervasive Computational Trust 

      Seigneur, Jean-Marc; Jensen, Christian D. (Trinity College Dublin, Department of Computer Science, 2004-11)
      A central element in the human notion of trust is to identify whom or what is under consideration. In the digital world, this is harder to achieve due to more or less trustworthy technical infrastructure between interacting ...
