Toward the automation of business process ontology generation
Semantic Business Process Management (SBPM) utilises semantic technologies (e.g., ontology) to model and query process representations. There are times in which such models must be reconstructed from existing textual documentation. In this scenario the automated generation of ontological models would be preferable, however current methods and technology are still not capable of automatically generating accurate semantic process models from textual descriptions. This research attempts to automate the process as much as possible by proposing a method that drives the transformation through the joint use of a foundational ontology and lexico-semantic analysis. The method is presented, demonstrated and evaluated. The original dataset represents 150 business activities related to the procurement processes of a case study company. As the evaluation shows, the proposed method can accurately map the linguistic patterns of the process descriptions to semantic patterns of the foundational ontology to a high level of accuracy, however further research is required in order to reduce the level of human intervention, expand the method so as to recognise further patterns of the foundational ontology and develop a tool to assist the business process modeller in the semi-automated generation of process models
Numerical simulation of Faraday waves
We simulate numerically the full dynamics of Faraday waves in three
dimensions for two incompressible and immiscible viscous fluids. The
Navier-Stokes equations are solved using a finite-difference projection method
coupled with a front-tracking method for the interface between the two fluids.
The domain of calculation is periodic in the horizontal directions and bounded
in the vertical direction by two rigid horizontal plates. The critical
accelerations and wavenumbers, as well as the temporal behaviour at onset are
compared with the results of the linear Floquet analysis of Kumar and Tuckerman
[J. Fluid Mech. 279, 49-68 (1994)]. The finite amplitude results are compared
with the experiments of Kityk et al. [Phys. Rev. E 72, 036209 (2005)]. In
particular we reproduce the detailed spatiotemporal spectrum of both square and
hexagonal patterns within experimental uncertainty

Experiences of generating COTS components when automating medicinal product evaluations
This paper reports on experiences of generating COTS
components when designing and deploying component based
software architecture for automation and interoperation of
medicinal product evaluations across different countries in the world. Our generic architectural model renders two sets of software components that are candidates for COTS components.
We identify which role such COTS components may play and
outline our approach of generating them. We advocate that such COTS components are developed with a specific component
platform in mind and must adhere to constraints of our software architecture
Outsourcing network management
The paper analyses the current situation in
outsourcing of IT and network management
through the literature review and examples in
industry. We have focused on trends, benefits
and risks in outsourcing network management
and made proposals to address the problems
through a carefully managed network
outsourcing relationship. The available statistics
and the the survey of six UK companies has
revealed that the upfront negotiation of service
level agreements should be one of the most
important aspects of conducting the outsourcing
of network management
Design patterns for automation of marketing authorisations in pharmaceutical industry
This paper reports on the experiences
of using existing and creating new design
patterns when deploying layered and component
based software architecture that automates
procedures for marketing authorization. We use
the strategy pattern within the generic
architecture and deploy the architectural
components with the Model-View-Controller
(MVC) and front controller patterns. Three
domain specific patterns have been created and
named as: look-up, submission and evaluation.
We advocate that our combination of general and
domain specific patterns (i) facilitate the design
of distributed software applications, (ii) can be
reused in any problem domain where workflows
similar to submission and evaluations of
application licenses occur, and (iii) comprise
commercial-off-the-shelf (COTS) components
that fit within our software architecture
Numerical simulation of super-square patterns in Faraday waves
We report the first simulations of the Faraday instability using the full
three-dimensional Navier-Stokes equations in domains much larger than the
characteristic wavelength of the pattern. We use a massively parallel code
based on a hybrid Front-Tracking/Level-set algorithm for Lagrangian tracking of
arbitrarily deformable phase interfaces. Simulations performed in rectangular
and cylindrical domains yield complex patterns. In particular, a
superlattice-like pattern similar to those of [Douady & Fauve, Europhys. Lett.
6, 221-226 (1988); Douady, J. Fluid Mech. 221, 383-409 (1990)] is observed. The
pattern consists of the superposition of two square superlattices. We
conjecture that such patterns are widespread if the square container is large
compared to the critical wavelength. In the cylinder, pentagonal cells near the
outer wall allow a square-wave pattern to be accommodated in the center
