   abstract = {The efficient and effective design, execution and adaption of its core processes is vital for the success of most businesses and a major source of competitive advantage. Despite this critical importance, process optimization today largely depends on manual analytics and the ability of business analysts to spot the ``right'' designs and areas of improvement. This is because current techniques typically fall short in three areas: They fail to integrate relevant data sources, they do not provide optimal analytical procedures and they leave it up to the analyst to identify the best process design. Hence, we propose in this paper a platform that enables (semi-)automated process optimization during the process design, execution and analysis stage, based on insights from specialized analytical procedures running on an integrated warehouse containing both process and operational data. We further detail the analysis stage, as it provides the foundation for all other optimization stages.},

   abstract = {Location-based applications and services gain in importance as the spread of mobile devices equipped with GPS sensors and internet capabilities increases. Moreover, there is a trend towards customizable applications in order to let the user determine e.g. the content and the look and feel. Nevertheless, there exist only a few applications combining these features. In this paper, we propose Gamework, a framework for customizable mobile location-based games as a specialization for customizable mobile context-aware applications and services. According to their programming skills players are able to adapt a game with Gamework. This can be done by changing the context, adding user-generated content, modifying the game-flow or implementing new games from scratch by reusing existing modules of the framework or adding new ones. Therefore our framework features a reuse-oriented development methodology as well as a feedback loop analyzing all accruing user-generated content. The results of this analysis are used to automatically optimize the game with respect to frequent user-feedback. Finally, we will transfer the results back to the more general area of mobile and context-aware applications and services.},

   abstract = {Nowadays, one of the main challenges for companies is the effective management of IT-systems. In times where requirements and companies change steadily, the ITinfrastructure has to adopt these changes as well: new systems have to be integrated or existing adapted. Even worse, these systems work together to support business processes of a company and, thus, the infrastructures becomes complex and difficult to manage. The same situation is true for Product Lifecycle Management (PLM) that accompanies a product development by means of interconnected IT systems running on complex IT infrastructures. This paper introduces a viable solution to the integration of all phases of PLM. An Enterprise Service Bus (ESB) is employed as the service-based integration and communication infrastructure. Three exemplary scenarios are introduced to describe the benefits of using an ESB as compared to alternative PLM infrastructures. Furthermore, we introduce a service hierarchy to enable value-added services to enhance PLM functionality.},

   abstract = {Volatile markets and constantly changing business conditions force manufacturing enterprises to continuously adapt their digital factory information systems. In many industries there is still no backbone for the integration of factory information systems. Current integration is based on point-to-point interfaces, which is partially due to the cost of replacing their established legacy systems. Furthermore the lack of flexibility prevents business processes to improve their responsiveness and adapt workflows of manufacturing to different turbulences. The principles of Service-Oriented Architecture (SOA) and its associated technologies (e. g., Enterprise Service Bus) and standards are key enabler and driver of the required flexibility. The presented Manufacturing Service Bus is a SOA-based approach that extends the Enterprise Service Bus capabilities in three areas: event management, factory context semantics and change propagation workflows. The Manufacturing Service Bus provides an event-driven platform for flexible integration of digital factory applications.},

   abstract = {Context aware systems use context information to adapt their behaviour accordingly. In order to derive high level context information from low level context, such as sensor values, context reasoning methods that correlate observable context information, are necessary. Several context reasoning mechanisms have been proposed in the literature. Usually these mechanisms are centralized, leading to suboptimal utilization of network resources and poor system performance in case of large-scale scenarios. Therefore to increase the scalability of context reasoning systems the development of methods that distribute the reasoning process is necessary. Existing distributed approaches are method specific and do not provide a generic formalization for distributed reasoning. In this paper we introduce a novel system which enables distributed context reasoning in a generic way that is independent of the reasoning algorithm.},

   abstract = {Online Analytical Processing (OLAP) is a popular technique for explorative data analysis. Usually, a fixed set of dimensions (such as time, place, etc.) is used to explore and analyze various subsets of a given, multi-dimensional data set. These subsets are selected by constraining one or several of the dimensions, for instance, showing sales only in a given year and geographical location. Still, such aggregates are often not enough. Important information can only be discovered by combining several dimensions in a multidimensional analysis. Most existing approaches allow to add new dimensions either statically or dynamically. These approaches support, however, only the creation of global dimensions that are not interactive for the user running the report. Furthermore, they are mostly restricted to data clustering and the resulting dimensions cannot be interactively refined. In this paper we propose a technique and an architectural solution that is based on an interaction concept for creating OLAP dimensions on subsets of the data dynamically, triggered interactively by the user, based on arbitrary multi-dimensional grouping mechanisms. This approach allows combining the advantages of both, OLAP exploration and interactive multidimensional analysis. We demonstrate the industry-strength of our solution architecture using a setup of IBM® InfoSphere™ Warehouse data mining and Cognos® BI as reporting engine. Use cases and industrial experiences are presented showing how insight derived from data mining can be transparently presented in the reporting front end, and how data mining algorithms can be invoked from the front end, achieving closed-loop integration.},

   abstract = {The number of pervasive games is growing in which players have to interact with their environment in order to control their avatar. While in the past they required immense hardware equipment, nowadays, smartphones have all required functionality built-in already. In addition, there is an upcoming trend towards software, supported with new content and knowledge by an active community. By combining these two trends, a new genre of computer games arises, targeting not only established gamers but also new audiences. We build four customization classes differing in required player's programming knowledge, support by the games and scale of adaption potential. With Gamework we present a framework for pervasive games on modern smartphones simplifying user-driven game customization for the identified customization methods in this paper. We also present two games implemented with this framework. Concluding, we show the potential of these games as well as the potential of our framework. We also report on early experiences in exploiting the customization approach of our framework.},

   abstract = {With the increasing use of sensor technology, the compression of sensor data streams is getting more and more important to reduce both the costs of further processing as well as the data volume for persistent storage. A popular method for sensor data compression is to smooth the original measurement curve by an approximated curve, which is bounded by a given maximum error value. Measurement values from positioning systems like GPS are an interesting special case, because they consist of two spatial and one temporal dimension. Therefore various standard techniques for approximation calculations like regression or line simplification algorithms cannot be directly applied. In this paper, we portray our stream data management system NexusDS and an operator for compressing sensor data. For the operator, we implemented various compression algorithms for position data streams. We present the required adaptations and the different characteristics of the compression algorithms as well as the results of our evaluation experiments, and compare them with a map matching approach, specifically developed for position data.},

The lack of flexibility prevents manufacturing companies to improve their responsiveness and to adapt their workflows to turbulent scenarios. In order to achieve highly flexible and adaptive workflows, information systems in digital factories and shop floors need to be integrated. The most challenging problem in such manufacturing environments is the high heterogeneity of the IT landscape, where the integration of legacy systems and information silos has lead to chaotic architectures over the last two decades. In order to overcome this issue, we present a flexible integration platform that allows a loose coupling of distributed services in event-driven manufacturing environments. Our approach enables a flexible communication between digital factory and shop floor components by introducing a service bus architecture. Our solution integrates an application-independent canonical message format for manufacturing events, content-based routing and transformation services as well as event processing workflows.},

This paper evaluates different resource discovery protocols in Bluetooth-based ad-hoc smart spaces. We simulate the protocols in different scenarios taking into account the scatternet structure of the network. We suggest request flooding for small settings and random replication for medium to large spaces.},

   abstract = {Semantic Web technologies, most notably RDF, are well-suited to cope with typical challenges in spatial data management including analyzing complex relations between entities, integrating heterogeneous data sources and exploiting poorly structured data, e.g., from web communities. Also, RDF can easily represent spatial relationships, as long as the location information is symbolic, i.e., represented by places that have a name. What is widely missing is support for geographic and geometric information, such as coordinates or spatial polygons, which is needed in many applications that deal with sensor data or map data. This calls for efficient data management systems which are capable of querying large amounts of RDF data and support spatial query predicates. We present a native RDF triple store implementation with deeply integrated spatial query functionality. We model spatial features in RDF as literals of a complex geometry type and express spatial predicates as SPARQL filter functions on this type. This makes it possible to use W3C's standardized SPARQL query language as-is, i.e., without any modifications or extensions for spatial queries. We evaluate the characteristics of our system on very large data volumes.},

   abstract = {A wide range of real-time applications process stream-based data. To process this stream-based data in an application-independent manner, many stream processing systems have been built. However, none of them reached a huge domain of applications, such as databases did. This is due to the fact that they do not consider the specific needs of real-time applications. For instance, an application which visualizes stream-based data has stringent timing constraints, or may even need a specific hardware environment to smoothly process the data. Furthermore, users may even add additional constraints. E.g., for security reasons they may want to restrict the set of nodes that participates in processing. Thus, constraints naturally arise on different levels of query processing. In this work we classify constraints that occur on different levels of query processing. Furthermore we propose a scheme to classify the constraints and show how these can be integrated into the query processing of the distributed data stream middleware NexusDS.},

   abstract = {A profound analysis of all relevant business data in the company is necessary for optimizing business processes effectively. Current analyses typically exclusively run on business process execution data or on operational business data stored in a data warehouse. However, to achieve a more informative analysis and to fully optimize a company’s business, a consolidation of all major business data sources is indispensable. Recent matching algorithms are insufficient for this task, since they are restricted either to schema or to process matching. Our demonstration presents BIAEditor that allows to annotate and match process variables and operational data models in order to perform such a global business impact analysis.},
