An integrated product and process information modelling system for on-site construction
The inadequate infrastructure that exists for seamless project team communications has its
roots in the problems arising from fragmentation, and the lack of effective co-ordination
between stages of the construction process. The use of disparate computer-aided engineering (CAE) systems by most disciplines is one of the enduring legacies of this problem and makes information exchange between construction team members difficult and, in some cases, impossible. The importance of integrating modelling techniques with a view to creating an integrated product and process model that is applicable to all stages of a construction project's life cycle, is being recognised by the Construction Industry. However, improved methods are still needed to assist the developer in the definition of information model structures, and current modelling methods and standards are only able
to provide limited assistance at various stages of the information modelling process. This research investigates the role of system integration by reviewing product and process
information models, current modelling practices and modelling standards in the construction industry, and draws conclusions with similar practices from other industries, both in terms of product and process representation, and model content. It further reviews various application development tools and information system requirements to support a suitable integrated information structure, for developing an integrated product and process model for design and construction, based on concurrent engineering principles. The functional and information perspectives of the integrated model, which were represented using IDEFO and the unified modelling language (UML), provided the basis for
developing a prototype hyper-integrated product and process information modelling system (HIPPY). Details of the integrated conceptual model's implementation, practical application of the prototype system, using house-building as an example, and evaluation by industry practitioners are also presented. It is concluded that the effective integration of product and process information models is a key component of the implementation of concurrent engineering in construction, and is a vital step towards providing richer information representation, better efficiency, and the flexibility to support life cycle information management during the construction stage of small to medium sized-building projects

Integrating Data Mining and Social Network Techniques into the Development of a Web-based Adaptive Play-based Assessment tool for School Readiness.
A major challenge that faces most families is effectively anticipating how ready to
start school a given child is. Traditional tests are not very effective as they depend on
the skills of the expert conducting the test. It is argued that automated tools are more
attractive especially when they are extended with games capabilities that would be
the most attractive for the children to be seriously involved in the test. The first part
of this thesis reviews the school readiness approaches applied in various countries.
This motivated the development of the sophisticated system described in the thesis.
Extensive research was conducted to enrich the system with features that consider
machine learning and social network aspects. A modified genetic algorithm was
integrated into a web-based stealth assessment tool for school readiness. The
research goal is to create a web-based stealth assessment tool that can learn the user's
skills and adjust the assessment tests accordingly. The user plays various sessions
from various games, while the Genetic Algorithm (GA) selects the upcoming session
or group of sessions to be presented to the user according to his/her skills and status.
The modified GA and the learning procedure were described. A penalizing system
and a fitness heuristic for best choice selection were integrated into the GA. Two
methods for learning were presented, namely a memory system and a no-memory
system. Several methods were presented for the improvement of the speed of
learning. In addition, learning mechanisms were introduced in the social network
aspect to address further usage of stealth assessment automation. The effect of the
relatives and friends on the readiness of the child was studied by investigating the
social communities to which the child belongs and how the trend in these
communities will reflect on to the child under investigation.
The plan is to develop this framework further by incorporating more information
related to social network construction and analysis. Also, it is planned to turn the
framework into a self adaptive one by utilizing the feedback from the usage patterns
to learn and adjust the evaluation process accordingly
