Application Of Microsimulation Towards Modelling Of Behaviours In Complex Environments, Daniel Keep, Rachel Bunder, Ian Piper, Anthony Green
Application Of Microsimulation Towards Modelling Of Behaviours In Complex Environments, Daniel Keep, Rachel Bunder, Ian Piper, Anthony Green
Dr Ian Piper
In this paper, we introduce new capabilities to our existing microsimulation framework, Simulacron. These new capabilities add the modelling of behaviours based on motivations and improve our existing non-deterministic movement capacity. We then discuss the application of these new features to a simple, synthetic, proof of concept, scenario involving the transit of people through a corridor and how an induced panic affects their throughput. Finally we describe a more complex scenario, which is currently under development, involving the detonation of an explosive device in a major metropolitan transport hub at peak hour and the analysis of subsequent reaction.
Application Of Microsimulation To The Modelling Of Terrorist Attacks, Ian Piper, Daniel Keep, Tony Green, Ivy Zhang
Application Of Microsimulation To The Modelling Of Terrorist Attacks, Ian Piper, Daniel Keep, Tony Green, Ivy Zhang
Dr Ian Piper
In this paper, a novel approach to behavioural modelling is presented with reference to biological infection spread in communities. Its potential application to various terrorist-related scenarios is discussed in relation to attack point simulation and interdiction simulation.
The Application Of Microsimulation To Threat Modelling, Tony Green, Nicola Davies, Chris Flaherty, Ian Piper, Daniel Keep, Rachel Bunder
The Application Of Microsimulation To Threat Modelling, Tony Green, Nicola Davies, Chris Flaherty, Ian Piper, Daniel Keep, Rachel Bunder
Dr Ian Piper
This paper summarises the current research on the use of microsimulation and its use for understanding behaviour in modelling threat in society. The motivation for this project was to develop simulation tools that could be used to model human behaviour and overlay that behaviour with a full spectrum of threats to understand how alternative ways for undertaking prevention, protection and response could be used to reduce the risk from a threat. The basic simulation engine - Simulacron, and its associated modules are briefly described. A number of applications to biological infection, including single vector infectious disease spread, biological weapon placement …
Simulations In 3d Tactics, Interdiction And Multi-Agent Modelling, A. R. Green, I. C. Piper, Daniel Keep, C. J. Flaherty
Simulations In 3d Tactics, Interdiction And Multi-Agent Modelling, A. R. Green, I. C. Piper, Daniel Keep, C. J. Flaherty
Dr Ian Piper
The analysis of vulnerabilities in large complex spaces is fundamentally problematic. The lack of capacity to generate a threat assessment merely exacerbates this problem. Lacking as well, in current literature is a developed methodology. To overcome this problem, we propose an approach using multi-agent modelling, which is also melded with three dimensional (3D) tactical understandings. Our approach builds on a microsimulation decision support tool, which was developed for a behavioural simulation of CBRN events. Microsimulation is based on the individual; who as an individual has a number of attributes, and which are stochastic (when repeated within an attribute). This approach …
A Hybrid Approach To The Core Curriculum, I. Piper, P. Castle, A. Fuller, G. Awyzio
A Hybrid Approach To The Core Curriculum, I. Piper, P. Castle, A. Fuller, G. Awyzio
Dr Ian Piper
In this paper we review the IEEE/ACM CC2001 model. We then describe our proposed core CS curriculum comprising four strands: programming languages, algorithms, discrete mathematics and systems. These sequences are to be taught over the first two years of the Bachelor of Computer Science Degree and need to be taken in parallel.
An Application Of The 5-S Activity Theoretic Requirements Method, Robert Brown, Peter Hyland, Ian Piper
An Application Of The 5-S Activity Theoretic Requirements Method, Robert Brown, Peter Hyland, Ian Piper
Dr Ian Piper
One of the most crucial aspects of highly interactive, multi-user, organisational systems is the interface. The Human Computer Interaction (HCI) community has not adopted rigorous Formal Methods with open arms (Paterno, 1996). However, the HCI community has widely adopted Usability Engineering approaches (Corporate Solutions 2006), such as Nielsen’s (1994), which offers considerable formality. There remains, however, scope for user interface (UI) design to adopt a theoretical framework to enhance consistency across the whole design and development lifecycle. A theoretically-consistent framework from initial conceptual elicitation to evaluation of the finished product may prove useful. Since the aim of UI design is …
Simple, Robust And Accurate Head-Pose Tracking Using A Single Camera, S. Meers, Koren Ward, I. Piper
Simple, Robust And Accurate Head-Pose Tracking Using A Single Camera, S. Meers, Koren Ward, I. Piper
Dr Ian Piper
This paper describes an inexpensive, robust method for tracking the head position and orientation of the user by using a single low-cost USB camera and infrared light emitting diodes concealed within spectacle frames worn by the user. Unlike gaze and head-pose tracking systems which rely on high-resolution stereo cameras and complex image processing hardware and software to find and track facial features on the user, the proposed system is able to efficiently locate and track the head's orientation and distance relative to the camera with little processing. Due to the infrared light emitting diodes having fixed geometry, the system does …
Introducing N-Tree-Space: A Classification System For Knowledge Library Applications, E. Rayner, I. C. Piper, M. Bunder
Introducing N-Tree-Space: A Classification System For Knowledge Library Applications, E. Rayner, I. C. Piper, M. Bunder
Dr Ian Piper
This paper identifies and defines the Knowledge Library Application (KLA) class. KLAs are an important class of information resource/knowledge management applications. It will be clear from the definition that KLAs are highly relevant to both the commercial and academic worlds and existing techniques such as keyword and tree classification, On-Line Analytical Processing (OLAP), and Formal Concept Analysis (FCA) do not provide key KLA features. N-Tree-Space (NTS), a technique detailed in this paper, enables the provision of these features and should facilitate the development of a range of KLAs that offer significant advantages over currently available software tools.
