  abstract     = {{For a fixed virtual scene (=collection of simplices) S and given observer
position p, how many elements of S are weakly visible (i.e. not fully occluded
by others) from p? The present work explores the trade-off between query time
and preprocessing space for these quantities in 2D: exactly, in the approximate
deterministic, and in the probabilistic sense. We deduce the EXISTENCE of an
O(m^2/n^2) space data structure for S that, given p and time O(log n), allows
to approximate the ratio of occluded segments up to arbitrary constant absolute
error; here m denotes the size of the Visibility Graph--which may be quadratic,
but typically is just linear in the size n of the scene S. On the other hand,
we present a data structure CONSTRUCTIBLE in O(n*log(n)+m^2*polylog(n)/k)
preprocessing time and space with similar approximation properties and query
time O(k*polylog n), where k<n is an arbitrary parameter. We describe an
implementation of this approach and demonstrate the practical benefit of the
parameter k to trade memory for query time in an empirical evaluation on three
classes of benchmark scenes.}},

  abstract     = {{In model-driven development approaches, process models are used at different levels of abstraction and are described by different languages. Similar to other software artifacts, process models are developed in team environments and underlie constant change. This requires reusable techniques for the detection of changes between different process models and the computation of dependencies and conflicts between changes. In this paper, we propose a framework for the construction of process model change management solutions that provides generic techniques for the detection of differences and the computation of dependencies and conflicts between changes. The framework contains an abstract representation for process models that serves as a common denominator for different process models. In addition, we show how the framework is instantiated exemplarily for BPMN.}},

  abstract     = {{Enterprises are transforming into enterprises which follow from a business as well as from an IT perspective a service-oriented paradigm. This change towards service-oriented enterprise and IT architectures has to be reflected in the methodologies of developing whole application landscapes as well as individual applications. Quasar (Quality Software Architecture) has been developed as the standard architecture and development method of Capgemini sd&m for individual applications. For the development of service-oriented enterprise application landscapes, Quasar Enterprise has been designed. Both Quasar and Quasar Enterprise are integrated with each other within a holistic software engineering method to seamlessly cover the full development lifecycle of service-oriented application landscapes, from business modeling and service design to actual software development. In this paper, we illustrate how a company-wide ontology of development artifacts serves as the key feature for integrating both methods.}},

  abstract     = {{Version management of models is common for structural diagrams such as class diagrams but still challenging for behavioral models such as process models. For process models, conflicts of change operations are difficult to resolve because often dependencies to other change operations exist. As a consequence, conflicts and dependencies between change operations must be computed and shown to the user who can then take them into account while creating a consolidated version. In this paper, we introduce the concepts of dependencies and conflicts of change operations for process models and provide a method how to compute them. We then discuss different possibilities for resolving conflicts. Using our approach it is possible to enable version management of process models with minimal manual intervention of the user.}},
