Abstract

Model transformations, together with models, form the principal artifacts in model-driven software development. Industrial practitioners report that transformations on larger models quickly get sufficiently large and complex themselves. To alleviate entailed maintenance efforts, this thesis presents a modularity concept with explicit interfaces, complemented by software visualization and clustering techniques. All three approaches are tailored to the specific needs of the transformation domain.

Abstract

The reuse of process models is a promising technique to reduce modelling effort. Yet, finding similar models in large model collections is not feasible manually. A search functionality for relevant models, which can be used as a template, is therefore helpful. This work describes multiple techniques for finding similar process models and acitvities in process model repositories.

Abstract

This work presents a new approach for a hail loss model to quantify the hail risk on residual buildings for high return periods. Based on the analysis of 3D radar data from 2005 to 2015 a stochastic hail track model is developed to sample a random number of stochastic hail tracks. A detailed vulnerability analysis combines the hazard from the hail tracks and the vulnerability of buildings towards hail and leads to the hail risk for a certain portfolio.

Abstract

In the present work a systematic approach is presented. With this approach it is possible to take concerted simplifications in building models of power train systems of mobile machines. The adopted systematic simplifications are aimed essentially of reducing the order of the system. The basis for this is the introduction of hydraulic replacement elements. Their mathematical structure is based on reduced-dynamic, stationary and event-oriented considerations.

Abstract

This book deals with the Boolean model, a basic model of stochastic geometry for the description of porous structures like the pore space in sand stone. The main result is a formula which gives in two and three dimensions a series representation of the most important model parameter, the intensity, using densities of so-called harmonic intrinsic volumes, which are new observable geometric quantities.

Abstract

With the advent of high performance computing, the application areas of the phase-field method, traditionally used to numerically model the phase transformation in metals and alloys, have now spanned into geoscience. A systematic investigation of the two distinct scientific problems in consideration suggest a strong influence of interfacial energy on the natural and induced pattern formation in diffusion-controlled regime.

Abstract

In this work, various simulation methods of the effective radar reflectivity factor and its attenuation by atmospheric particles from the variables of the COSMO model have been implemented within a so-called radar forward operator, and its output was compared to measurements from the German radar network. To perform a statistically reliable model verification, contoured frequency by altitude diagrams (CFADs) were used and refined.

Abstract

Hydraulic structures are exposed to multifaceted exposures. Particular the hydro-abrasive wear of the concrete edge zones represents a key exposure. The knowledge about the abrasive mechanisms of concrete and its degradation process is still insufficient. Relating to the hydro-abrasive test method, the relevant material parameter and degradation model incomplete knowledge existed which was removed.

Abstract

Modern software development faces the problem of fragmentation of information across heterogeneous artefacts in different modelling and programming languages. In this dissertation, the Vitruvius approach for view-based engineering is presented. Flexible views offer a compact definition of user-specific views on software systems, and can be defined the novel ModelJoin language. The process is supported by a change metamodel for metamodel evolution and change impact analysis.

Abstract

Following the research principle of economy the simplest and most suitable simulation model should be preferred over more complex ones. This allows a high goodness of fit to existing measuring data with a high generalizability during the simulation of virtual prototypes. In addition, testing effort and simulation time can be reduced. For this reason quantification attributes are researched in this book, granting an optimal simulation model complexity depending on different simulation purposes.
