Robust Real-Time Synchronization between Textual and Graphical Editors

Modeling languages such as Behavior Trees or QVT Relational provide both textual and graphical concrete syntaxes. Textual and graphical editors for such languages need to synchronize textual representations, graphical representations, and underlying models. During this synchronization, layout in textual and graphical representations needs to be...

Smart-grid management using Java-based Complex Event Processing

The ageing electricity grid cannot sustain the growth in electricity demand for much longer without renewing the current way of working. This thesis proposes a new way by introducing smart-grid and complex event processing for the management of the smart grid.

Dynamic User Interface Supporting Type Analysis for RDFGears

This thesis describes the design and implementation of an interactive, dynamic and functional web-based Graphical User Interface for RDFGears. RDFGears is a data integration framework for the semantic web. It allows users to express and execute complex data algorithms without the need to be concerned with the implementation details. The...

Schema-Based Partitioning for Optimized Querying of XML data

Efficient querying and retrieval of data from XML databases is a challenging task, especially when these DBs contain a large number of documents, potentially millions of them. One way to scale out is by spreading the documents over multiple nodes, but running all queries on all nodes has poor scale-out qualities. Here we propose a solution to...

A Design for Six Sigma based predevelopment processes: Facilitated by a Product Lifecycle Management System

This thesis proposes a process including deliverables based on Design for Six Sgima to be used in predevelopment which is supported by a Product Lifecycle Management System.

Analysis of high-volume traffic using Complex Event Processing and a Domain Specific Language

In the online travel environment it is physically and economically not possible to retrieve the hotel room rates in real-time for every customer request. To overcome this problem the hotel rates are cached, but due to the fact that the suppliers will not send notifications of price changes it is a challenging task to keep the cache up to date....

Partial Migration of Business Data to The Cloud

Cloud computing has led to large pools of interconnected computer resources that can be acquired or released in a matter of minutes. No long-term contracts or large upfront investment required; resources are available on a pay-per-use basis. Consequently, a thousand servers used for an hour are as expensive as using one server for a thousand...

RDF Gears, a data integration framework for the Semantic Web

This thesis describes the design and implementation of RDF Gears, a data integration framework for the Semantic Web. The RDF Gears Language combines the Semantic Web technologies with the Nested Relational Algebra. It provides an expressive Domain Specific Language for the development of workflows integrating RDF data with other sources. It...

Researching a transition to an organized chaos in enterprise system architectures

After its founding 15 years ago, Tam Tam has encountered the limits of legacy systems used for the internal processes in recent years. To overcome these limits, multiple efforts have been made to enforce a transition to specific Enterprise Application Integration styles. Although the efforts resulted in working application interactions, the...

Temporal Preference Analysis in Recommender Systems

The thesis presents the results of research into temporal preference analysis in recommender systems. Temporal preference analysis consists of methods for detecting time recurrent changes in user preferences and for using this information to improve the recommendation precision.

From business transactions to business process work flows: Using DEMO and BPMN

For many years Capgemini has been using the Integrated Architecture Framework (IAF) as guide for the formation of an enterprise architecture. The Integrated Architecture Framework (IAF) constitutes four abstraction levels: the contextual, the conceptual, the logical and the physical abstraction level. When forming an enterprise architecture, one...
