The Computational Modelling of Religious Concepts by Fr. Aloysius Hacker

• We apply ideas from Computer Science to the understanding of religious concepts.

• Previous attempts to explain religious concepts, – e.g. the holy trinity and miracles. have often encountered philosophical problems.

• These problems arose because the appropriate terminology was not available. – Computational terminology often provides an appropriate analogy.

• Although some problems still remain, – e.g. free will,

• We are seeing the beginning of a new, computational theology.

Planning Proofs of Correctness of CCS Systems by Raúl Monroy

1. The specification and verification of communicating systems have captured increasing interest, because they are error prone.

2. CCS was especially designed to help this enterprise, and is widely used in both industry and academia.

3. Existing methods to automate the use of CCS to verification have centred around finite-state systems, using bisimulations.

4. This, though, is insufficient to deal with systems that contain infinite states or a finite, but arbitrary, number of components, VIPS; there is an alternative approach, based on fixed point equations, which does not exhibit such limitations; however, automated verification in this context is extremely difficult.

5. This thesis investigates the use of explicit proof plans for automating the verification of VIPS.

6. We have extended inductive proof planning, with special plans that exploit both the inductive structure and

7. the expected behaviour of a system during its verification.8. With these plans, we have developed a fully automated verification

method, which has been successfully tested on a number of examples that are outside the domain of other, rival techniques.

9. Therefore, even though it has still got plenty of room for improvement.

10. Our techniqe successfully automates the equational approach to verification of CCS systems.

Towards Building a Masquerade Detection Method

1. Masquerade detection has been actively studied for more than a decade, especially after the seminal work of Schonlau’s group

2. Schonlau suggested that, to profile a user, one should model the history of the commands she would enter into a UNIX session; he developed a masquerade dataset, SEA, which has been the standard for comparing masquerade detection methods.

3. However, the performance of SEA-based methods is not conclusive, and, as a result, research on masquerade detection has resorted to other sources of information for profiling user behaviour.

4. We claim that to better characterise user behaviour, it is necessary to consider how and what the user browses while working on her own file system.

5. To capture this behaviour, we introduce a navigation structure, which contains information about the use (visit) of file system objects, and about the structure of the user file system; we have used the navigation structure to build a one-class classifier for masquerade detection.

6. While preliminary, our results are encouraging and suggest a number of ways in which new methods can be constructed.

detallada de cada capítulo, ejemplo:– “Chapter 1 introduces the general notion of computer

modelling and how it might be applied to religion by drawing analogies between computational concepts and religious ones to suggest consequences and non-consequences of religious positions, and hence debug some of the theological debate of the last two millenia.”
