    • Addressing Mechanisms for VLIW and Superscalar Processors 

      Steven, F.L.; Adams, R.G.; Steven, G.B.; Wang, L.; Whale, D. (1993)
      RISC processors employ simple addressing modes which allow memory addresses to be calculated in a single processor cycle. This paper demonstrates that VLIW and Superscalar processor performance can be improved by further ...

      Mapping is a fundamental requirement for robot navigation.In this paper, we introduce a novel visual mapping method that relies solely on a single omnidirectional camera.We present a metric that allows us to generate a map ...

    • The Agent-Based Perspective on Imitation 

      Dautenhahn, K.; Nehaniv, C.L. (MIT Press, 2002)
      This chapter presents the agent-based perspective on imitation. In this perspective, imitation is best considered as the behaviour of an autonomous agent in relation to its environment, including other autonomous agents. ...

      This article outlines what we learned from the first year of the AI Settlement Generation Competition in Minecraft, a competition about producing AI programs that can generate interesting settlements in Minecraft for an ...

    • Algebraic analysis of the computation in the Belousov-Zhabotinsky reaction 

      Dini, P.; Nehaniv, C.L.; Egri-Nagy, A.; Schilstra, M. (Springer Nature, 2012)
      We analyse two very simple Petri nets inspired by the Oregonator model of the Belousov-Zhabotinsky reaction using our stochastic Petri net simulator. We then perform the Krohn-Rhodes holonomy decomposition of the automata ...

    • Algebraic connectivity 

      Nehaniv, C.L. (1991)

    • All Else Being Equal Be Empowered 

      Klyubin, A.S.; Polani, D.; Nehaniv, C.L. (2005)
      The classical approach to using utility functions suffers from the drawback of having to design and tweak the functions on a case by case basis. Inspired by examples from the animal kingdom, social sciences and games we ...

    • Analysing Hierarchical Data Using a Stochastic Evolutionary Neural Tree 

      Adams, R.G.; Davey, N.; George, S. (1998)
      SCENT is simple competitive neural network model that evolves a tree structured set of nodes in response to being presented with an unlabelled data set. The resulting set of weight vectors and their relationship can be ...

    • Analysing psychological data by evolving computational models 

      Lane, Peter; Gobet, Fernand; Addis, Mark; Sozou, Peter (Springer Nature, 2016)

    • Analysis and implementation of semi-automatic model for vulnerability exploitations of threat agents in NIST databases 

      Sharma, Gaurav; Vidalis, Stilianos; Menon, Catherine; Anand, Niharika (2023-05-30)
      Proactive security plays a vital role in preventing the attack before entering active mode. In the modern information environment, it depends on the vulnerability management practitioners of an organization in which the ...

    • Analysis and Implementation of Threat Agents Profiles in Semi-Automated Manner for a Network Traffic in Real-Time Information Environment 

      Gaurav, Gaurav Sharma; Vidalis, Stilianos; Menon, Catherine; Anand, Niharika; Kumar, Somesh (2021-07-31)
      Threat assessment is the continuous process of monitoring the threats identified in the network of the real-time informational environment of an organisation and the business of the companies. The sagacity and security ...

    • The analysis of animate object motion using neural networks and snakes 

      Tabb, Ken; George, S.; Davey, N.; Adams, R.G. (2000)
      This paper presents a mechanism for analysing the deformable shape of an object as it moves across the visual field. An object’s outline is detected using active contour models, and is then re-represented as shape, location ...

    • Analysis of DoS Attacks at MAC Layer in Mobile Adhoc Networks 

      Alocious, Chaminda; Xiao, Hannan; Christianson, B. (Institute of Electrical and Electronics Engineers (IEEE), 2015-10-05)
