Discrete event system modeling using SysML and model transformation
… is to introduce a unified framework for modeling and simulating discrete event logistics systems (DELS) by using a formal language, the System Modeling Language (SysML), for conceptual modeling and a corresponding methodology for translating the conceptual model into a simulation model. …

A Middleware Independent Service Modeling and a Model Transformation Framework
We believe that this research is a step towards the realization of the MDA approach.

Analysis and Optimization of Visual Enterprise Models Based on Graph and Model Transformation
… wachsender Bedeutung im Bereich der Unternehmens-Modellierung. In einer Analyse von realen Szenarien im Bankenbereich wurde deutlich, dass heutige "Best Practices", die auf informellen Techniken basieren, nicht ausreichen und durch adäquate formale Techniken ersetzt werden sollten. Zu diesem Zweck …

A Comparative Analysis To Validate The Benefits Of Formal Versus Informal Software Model Transformation
<p>In object -oriented development the Unified Modeling Language (UML) is the ISO/IEC standard for modeling language and is supported by major corporations. In relational database development, entity-relationship models have traditionally been use for modeling such systems. Transforming from one …

Business model transformation for the international division of a fortune 100 high technology company
… Raytheon Corporation, the company has a business model similar to its parent company. The company however is facing new trends in its business environment which have characteristics different than those of its parent company. The main focus of this thesis is to identify the key missing elements in …

A Comparative Study of Model Transformation Approaches through a Systematic Procedural Framework and Goal Question Metrics Paradigm
Model Driven Engineering has become a key Software Engineering approach, which aims at improving the cost-effectiveness and reusability of software by capturing the essential semantics of systems in models. By means of model transformations, these models can be analysed, improved, and mapped to …

Business model transformation influenced by Germany's Energiewende. A comparative case study analysis of business model innovation in start-up and incumbent firms
… thesis investigates the performance of business model innovation (BMI) by incumbent power utility and clean-tech start-up firms influenced by the German Energiewende. It emphasises the factors that impact BMI from a managers’ perspective, examines success factors for managers to overcome BMI …

Formal Verification of Relational Model Transformations using an Intermediate Verification Language
Model-driven engineering has been recognised as an effective way to manage the complexity of software development. Model transformation is widely acknowledged as one of its central ingredients. Among different paradigms of model transformations, we are specifically interested in relational model …

Measuring Incrementally Developed Model Transformations Using Change Metrics
Transformations play a central role in Model Based Software Engineering. Similar to the development of other types of software, a transformation's specification and implementation does not necessarily remain static over the course of a project's lifetime; the transformation may develop …

Model driven software modernisation
… area carries this idea further and moves into model driven perspective that the specification is presented with models. The thesis focuses on engaging model technology to modernise legacy systems. A unified approach, REMOST (Re-Engineering through MOdel conStruction and Transformation), is …

Automatic Derivation of Performance Models in the Context of Model-Driven SOA
The thesis proposes a model transformation chain called Performance from Unified Modeling Analysis for Service-Oriented Architecture (SOA) systems (PUMA4SOA), whose purpose is to automatically generate performance models from the UML software design models of SOA systems with performance …

An Integrated Framework Enhanced With Appearance Model for Facial Motion Modeling, Analysis and Synthesis
… intelligent video surveillance. Computational models for face analysis and synthesis are useful for both basic research and practical applications. In this dissertation, we present a unified framework for 3D face motion modeling, analysis and synthesis. We first derive a compact geometric …

Multimodal Fusion With Applications to Audio -Visual Speech Recognition
… for both applications. For audio-visual speech modeling, we propose a novel sensory fusion method based on the coupled hidden Markov models (CHMMs). The CHMM framework allows the fusion of two temporally coupled information sources to take place as an integral part of the statistical modeling …

RAS++: representing hybrid reuse assets for MDE as a service
Artifacts associated with Model-Driven Engineering (MDE) such as model transformations, Domain Specific Languages (DSL), and modeling or refinement tools have been proposed in the literature as a mean to increase the quality in products derived from activities of Software Engineering. These …

Design Space Decomposition for Cognitive and Software Defined Radios
… decomposes the radio definition to reactive models for the CE domain<br />and real-time, or dataflow models, for the SDR domain. By allowing such design space<br />decomposition, CEs are able to define implementation independent radio graphs and rely on<br />a model transformation layer to …

Traceability and model management with executable and dynamic hierarchical megamodels
Nowadays, model-driven engineering (MDE) promises to ease software development by decreasing the inherent complexity of classical software development. In order to deliver on this promise, MDE increases the level of abstraction and automation, through a consideration of domain-specific models …

Transformation of digital building models from boundary representation to tetrahedral space partitioning
… designed to transform a digital building model from a Boundary Representation (B-rep) to a tetrahedral space partitioning. This transformation addresses the limitations of current digital building models, especially their lack of explicit spatial relationship information among building …

A knowledge based reengineering approach via ontology and description logic.
… Ontology and description logic are employed to model and represent the knowledge in different software systems, which is integrated with domain knowledge. Model transformation is used to support ontology development. Description logic is used to implement ontology mapping algorithms, in which …

Multi-objective system optimisation with respect to availability, maintainability and cost
… and cost by establishing mathematical models for both policies. Secondly, a multi-objective optimisation approach is formulated for PM scheduling that takes into account dependability and cost, and finally the approach is evaluated on two case studies using a well-established …
