Gartner predicts that 33 per cent of total accesses to Business Intelligence (BI) functionalities will be done until 2013 using mobile devices. While mobile devices have already spread to a high extent in private life they have recently become more and more part of the professional life as well and businesses are seeking to develop smart scenarios on how to integrate the new technologies in their processes. The development of mobile software applications is also booming in the field of BI. The research topic of Mobile Business Intelligence (mBI) is focussing on how to expand traditional BI concepts to the new mobility dimension thus enabling to apply BI functionalities on mobile devices, such as smartphones and tablet computers. The increasing significance of mBI for research in combination with the tremendous economic growth potential forecasted for the next years is the driver for writing this thesis. The main aspect of the present thesis is a concept on how to develop a consistent mBI Strategy aligning all structures, processes and stakeholders to one standard set of goals and guidelines. Crucial points when implementing an mBI strategy are the definition of goals, the identification of risks and opportunities, the adaptation of mBI to the user context, the integration of mBI into the existing IT landscape, as well as a proper set-up of system architectures and security concepts. Besides analyzing the aspect of mBI strategy this thesis also considers the market situation of mBI. Clearly defined goals and the systematic development of a consistent mBI strategy which is in line with these goals can be considered as a crucial prerequisite for companies to successfully implement mBI.
Regarding the rapidly growing amount of data produced every year and the increasing acceptance of Enterprise 2.0 enterprises have to care about the management of their data more and more. Content created and stored in an uncoordinated manner can lead to data-silos (Williams & Hardy 2011, p.57), which result in long search times, inaccessible data and in consequence monetary losses. The "expanding digital universe" forces enterprises to develop new archiving solutions and records management policies (Gantz et al. 2007, p.13). Enterprise Content Management (ECM) is the research field that deals with these challenges. It is placed in the scientific context of Enterprise Information Management. This thesis aims to find out to what extent current Enterprise Content Management Systems (ECMS) support these new requirements, especially concerning the archiving of Enterprise 2.0 data. For this purpose, three scenarios were created to evaluate two different kinds of ECMS (one Open Source - and one proprietary system) chosen on the basis of a short marketrnresearch. The application of the scenarios reveals that the system vendors actually face the industry- concerns: both tools provide functionality for the archiving of data arising from online collaboration and also business records management capabilities but the integration of those topics is not, or is only inconsistently solved. At this point new questions - such as, "Which datarngenerated in an Enterprise 2.0 is worth being a record?" - arise and should be examined in future research.
Computers assist humans in many every-day situations. Their advancing miniaturisation broadens their fields of use and leads to an even higher significance and spread throughout society. Already, these small and powerful machines are wide-spread in every-day objects and the spread increases still as the mobility-aspect grows in importance. From laptops, smartphones and tables to systems worn on the body (wearable computing) or even inside the body as cyber-implants, these systems help humans actively and context-sensitively in the accomplishment of their every-day business.
A part of the wearable-computing-domain is taken up by the development of Head-mounted displays (HMD). These helmets or goggles feature one or more displays enabling their users to see computer-rendered images or images of their environment enriched with computer-generated information. At the moment, most of this HMD feature LC-Displays, but newer systems start appearing that allow the projection of the image onto the user's retina. Newest break-throughs in the field of study already produced contact lenses with an integrated display. The data shown by a HMD is compiled using a multitude of sensors, like a Head-Tracker or a GPS. Increasing computational performance and miniaturisation lead to a wide spread of HMD in a lot of fields.rnThe multiple scenarios in which a HMD can be used to help improve human-perception and -interaction led the "Institut für Integrierte Naturwissenschaften" of the University of Koblenz-Landau to come up with a HMD on the basis of Apple's iOS-devices featuring Retina Displays. The high pixel density of these displays combined with condensor lenses into a HMD offer a highly immersive environment for stereoscopic imagery, while other systems only display a relatively small image projected a few feet away of the user. Furthermore, the iPhone/ iPod Touch and iPad exhibit a lot of potential given by their variety of offered sensors and computational power. While producing a similarly feature-rich HMD is very costy, using simple iPod Touches 4th Gen as the basis of a HMD results in a very inexpensive solution with a high potential. The increasing popularity and spread of Apple devices would reduce the costs even more, as users of the HMD could simply integrate their device into the system. A software designed with the specific intent to support a large variety of Apple iOS-devices that could easily be extended to support newer devices, would allow for a universal use of such a HMD-solution as the new device could simply replace an old device.rnrnThe focus of this thesis is the conception and development of an application designed for Apple's iOS 5 operating system that will be used in a HMD evolving around the use of Apple iOS-devices featuring Retina Displays. The Rollercoaster2000-project depicting a ride in a virtual rollercoaster will be used as the application's core. A server will syncronize the display of clients conntected to it which are combined to form a HMD. Furthermore the gyroscope of the iOS-devices combined into a HMD will be used to track the wearer's head-movements. Another feature will be the use of the devices cameras as a mean of orientation while wearing the HMD.
As a first step in the realization of a software meeting the set specifications is the introduction of the Objective-C programming languages used to develop iOS-Applications. In conjunction with the compiler and runtime environment, Objective-C makes up the base of the second step, the introduction of the iOS-SDK. Aimed with this iOS-app-development-knowledge, the last part of the thesis consists of the ascertainment of requirements and development of a software complying to the goals of a software written specifically for the used in a HMD.
Mit der rasant fortschreitenden Entwicklung von Informatiksystemen und Algorithmen ist die Erfassung und Verarbeitung von Daten in immer größeren Umfang möglich. Verschiedene Initiativen haben sich dadurch motiviert zur Aufgabe gemacht, über die daraus resultierenden Gefahren für die Persönlichkeitsrechte und die Meinungsfreiheit aufzuklären. Dies soll einen bewussteren Umgang mit personenbezogenen Daten zur Folge haben. Zum Schutz der Grundrechte bedarf es aufgeklärter und informierter Nutzer, diese Aufgabe können die Initiativen allerdings nicht alleine leisten. Die staatlichen Bildungseinrichtungen und besonders die Schulen, stehen hier in der Pflicht sich an der Lösung des Problems zu beteiligen. Um ihrem Bildungsauftrag im vollen Ausmaß gerecht zu werden, bedarf es struktureller Änderungen, wie der Änderung von Lehrplänen. Solange diese allerdings nicht erfolgt sind, muss in und mit den gegebenen Strukturen gearbeitet werden. Eine Plattform dafür bietet der schulische Informatikunterricht.
Die vorliegende Arbeit stellt eine Unterrichtsreihe zur Behandlung von Datenschutz und Datensicherheit vor. Es wurde dabei ein kontextorientierter Ansatz nach Vorbild von Informatik im Kontext gewählt. Die Reihe Smartphone-Applikationen beinhaltet über die genannten primären Themen der Unterrichtsreihe hinaus weitere Dimensionen, die bei der Nutzung von Smartphones auftreten. Durch den direkten Bezug zum Alltag der Schüler soll dabei eine möglichst hohe Betroffenheit erzeugt werden. Dadurch sollen die Schüler ihr bisheriges Nutzungsverhalten überdenken und im besten Fall ihren Altersgenossen als Vorbilder dienen. Die Prüfung der Durchführbarkeit der Reihe im Unterricht steht noch aus. Diese war im Rahmen dieser Arbeit, begründet durch die begrenzte Bearbeitungszeit, nicht zu leisten.

Numerous communities pursue similar goals in this field of IT-based, strategic decision making and simulation of social problem areas. Though, the existing research approaches and results so far are quite fragmented. The aim of eGovPoliNet is to overcome the fragmentation across disciplines and to establish an international, open dialogue by fostering the cooperation between research and practice. This dialogue will advance the discussion and development of various problem areas with the help of researchers from different disciplines, who share knowledge, expertise and best practice supporting policy analysis, modelling and governance. To support this dialogue, eGovPoliNet will provide a knowledge base, which's conceptual development is the subject of this thesis. The knowledge base is to be filled with content from the area of ICT for strategic decision making and social simulation, such as publications, ICT solutions and project descriptions. This content needs to be structured, organised and managed in a way, so that it generates added value and the knowledge base is used as source of accumulated knowledge, which consolidates the previously fragmented research and development results in a central location.
The aim of this thesis is the development of a concept for a knowledge base, which provides the structure and the necessary functionalities to gather and process knowledge concerning ICT solutions for governance and policy modelling. This knowledge needs to be made available to users and thereby motivate them to contribute to the development and maintenance of the knowledge base.
Rescueanalyser
(2007)
Im Forschungsgebiet der Künstlichen Intelligenz und Multiagenten-Systeme stellt die Erkennung von Plänen eine besondere Herausforderung dar. Es gilt aus einer Menge von Beobachtungen Agentenpläne effektiv, zuverlässig und eindeutig zu identifizieren. Im Bereich des RoboCup ist es von entscheidender Bedeutung, dass Agenten über die Pläne und Intensionen anderer Agenten schlussfolgern können, um gemeinsame Ziele zu erreichen. Diese Diplomarbeit umfasst die Konzeption und Entwicklung eines Werkzeugs für die RoboCupRescue-Simulation, welches die Abläufe einer Rescue-Simulation analysiert und die beobachteten Aktionsfolgen Plänen einer vorspezifizierten Planbibliothek zuordnet. Das entwickelte Analysewerkzeug zeichnet sich einmal durch seine Unabhängigkeit von den verschiedenen Rescue-Agententeams aus, sowie durch die Verwendung neuester Methoden zur effektiven Planerkennung. Damit ermöglicht der entwickelte Rescueanalyser sowohl die Fehlersuche und Optimierung des eigenen Agententeams als auch die Erforschung und Auswertung unterschiedlicher Strategien der Rescue-Agenten konkurrierender Teams. Neben der Visualisierung der Ergebnisse mittels eines optimierten Monitors des Rescue-Simulators, können die Resultate und Auswertungen der Planerkennung auch durch textbasierte Ausgaben detailliert eingesehen werden.
On-screen interactive presentations have got immense popularity in the domain of attentive interfaces recently. These attentive screens adapt their behavior according to the user's visual attention. This thesis aims to introduce an application that would enable these attentive interfaces to change their behavior not just according to the gaze data but also facial features and expressions. The modern era requires new ways of communications and publications for advertisement. These ads need to be more specific according to people's interests, age, and gender. When advertising, it's important to get a reaction from the user but not every user is interested in providing feedback. In such a context more, advance techniques are required that would collect user's feedback effortlessly. The main problem this thesis intends to resolve is, to apply advanced techniques of gaze and face recognition to collect data about user's reactions towards different ads being played on interactive screens. We aim to create an application that enables attentive screens to detect a person's facial features, expressions, and eye gaze. With eye gaze data we can determine the interests and with facial features, age and gender can be specified. All this information will help in optimizing the advertisements.

Im Rahmen dieser Arbeit wird der Einfluss des Wahlszenarios auf die Geheimheit und Öffentlichkeit der Wahl herausgearbeitet. Ein Wahlszenario wird durch seine Wahlform und die verwendete Wahltechnik bestimmt. Bei der Wahl-form kann zwischen einer Präsenz- und einer Fernwahl unterschieden werden. Bei der Wahltechnik zwischen der Papier- und der elektronischen Wahl. Mit der Papier-Präsenzwahl, der Briefwahl (Papier-Fernwahl) und der Internetwahl (elektronische Fernwahl) werden drei prominente Wahlszenarien und ihr Einfluss auf Geheimheit, Privatheit und Öffentlichkeit untersucht.
In diesem Arbeitsbericht werden zuvor nicht identifizierte Bedrohungen bezüglich des Wahlgeheimnisses des in [BKG11] vorgeschlagenen Konzeptes zur Authentifizierung von Wählern bei elektronischen Wahlen mittels des neuen Personalausweises aufgezeigt. Überdies wird mit der Einführung einer zwischengelagerten Anonymisierungsschicht eine Lösung vorgeschlagen, wie eben diese Bedrohungen abgewehrt werden können.
In the "Institut MTI Mittelrhein" the impact of training and experience on motion and motion planning in sports is examined. As a part of these investigations, the motion behaviour of a sports climber is analyzed on a sports climbing wall. The aim of this thesis is the segmentation and marker-based detection of the movement of a climber in video recordings. The segmented markers from each image are tracked by a tracking procedure over time. The motion tracks will be exported to the motion analysis software Simi Motion in a format suitable for further analysis.

A trending topic in Semantic Web research deals with the processing of queries over Linked Open Data (LOD). As has been shown in literature, the loose nature of the "web of data" and data sources within can be accounted for by employing federated query processing strategies. This approach, however, is all the more dependent on both up-to-date statistical summaries (data statistics) of the sources in use and accurate and precise estimation of cardinalities and selectivities. In general, federated data sources are to be seen as black-boxes w.r.t. data statistics, as no interchange of such information can be expected. Because of this, it is possible for individual data statistics to become obsolete, if the corresponding source is subjected to data changes cumulating over time. In this thesis an adaptive system is being proposed, that complements a given RDF-based query federator. Through observation and analysis of the error of the cardinality estimation of incoming queries, it tries to infer the obsolescence of individual data statistics, triggering updates of data statistics found to be obsolete. An evaluation of the system shows, that the approach to this solution is plausible. Yet, in practice no satisfying results could be acquired, that would prove a true practicality. Still, parts of the system proposed may be re-used for related tasks that could be more promising.
Aufgrund des branchenweiten Bedarfs den Konkurrenzkampf zu umgehen, entwickelten Kim und Mauborgne die Blue Ocean Strategy, um neue Märkte zu ergründen. Diese bezeichnen sie als einzigartig. Da jedoch weitere Strategien zur Ergründung neuer Märkte existieren, ist es das Ziel dieser Arbeit herauszufinden, anhand welcher Charakterisierungsmerkmale die Blue Ocean Strategy als einzigartig angesehen werden kann.
Die Strategie von Kim und Mauborgne soll daher mit Schumpeters schöpferischen Zerstörung, Ansoffs Diversifikationsstrategie, Porters Nischenstrategie und Druckers Innovationsstrategien verglichen werden. Für den Vergleich werden die Charakterisierungsmerkmale herangezogen, nach denen Kim und Mauborgne die Blue Ocean Strategy als einzigartig beurteilen. Auf Basis dieser Kriterien wird ein Metamodell entwickelt, mit dessen Hilfe die Untersuchung durchgeführt wird.
Der Vergleich zeigt, dass die Konzepte von Schumpeter, Ansoff, Porter und Drucker in einigen Kriterien der Blue Ocean Strategy ähneln. Keine der Strategien verhält sich jedoch in allen Punkten so wie das Konzept von Kim und Mauborgne. Während die Blue Ocean Strategy ein Differenzierung und Senkung der Kosten anstrebt, orientieren sich die meisten Konzepte entweder an einer Differenzierung oder an einer Kostenreduktion. Auch die Betretung des neuen Marktes wird unterschiedlich interpretiert. Während die Blue Ocean Strategy auf einen Markt abzielt, der unergründet ist und somit keinen Wettbewerb vorweist, werden bei den anderen Strategien oft bestehende Märkte als neu interpretiert, auf denen das Unternehmen bisher nicht agiert hat. Dies schließt die vorherige Existenz der Märkte jedoch nicht aus.
Auf Basis der durch den Vergleich gezogenen Erkenntnisse, kann somit die Blue Ocean Strategy als einzigartig bezeichnet werden.
The novel mobile application csxPOI (short for: collaborative, semantic, and context-aware points-of-interest) enables its users to collaboratively create, share, and modify semantic points of interest (POI). Semantic POIs describe geographic places with explicit semantic properties of a collaboratively created ontology. As the ontology includes multiple subclassiffcations and instantiations and as it links to DBpedia, the richness of annotation goes far beyond mere textual annotations such as tags. With the intuitive interface of csxPOI, users can easily create, delete, and modify their POIs and those shared by others. Thereby, the users adapt the structure of the ontology underlying the semantic annotations of the POIs. Data mining techniques are employed to cluster and thus improve the quality of the collaboratively created POIs. The semantic POIs and collaborative POI ontology are published as Linked Open Data.
Die Computergrafik befasst sich mit der Erzeugung von virtuellen Bildern. Im Bereich der 3D-Computergrafik werden die dargestellten Objekte im dreidimensionalen Raum beschrieben. Dazu bedient man sich diverser Generierungsverfahren. Einer dieser so genannten Renderer ist das Raytracing-Verfahren. Es erfreut sich in der Computergrafik wegen der erreichten Bildqualität bei ueberschaubarer Komplexität großer Beliebtheit. Dabei wird versucht, immer realistischere Ergebnisse zu erreichen. In der Vergangenheit wurde Raytracing deswegen beispielsweise um globale Beleuchtungsmodelle oder um reflektierende beziehungsweise um transparente Objekte erweitert. Dabei wurde aber ein wichtiger Punkt häufig vernachlässigt, welcher ebenfalls den Grad an Realismus deutlich erhöhen kann: die Kamera. Meistens geht man auch heutzutage von einem vereinfachten Lochkameramodell aus. Aus diesem Grund genügen solche Modelle nicht den Ansprüchen physikalisch-korrekter Renderingverfahren. Eine wirklich umfassend korrekte Abbildung von Szenen darf also nicht vernachlässigen, dass ein generiertes Bild durch ein Linsensystem noch einmal entscheidend beeinflusst wird. In dieser Arbeit wird deswegen ein physikalisch korrektes Kameramodell vorgestellt, welches die geometrischen Eigenschaften des Linsensystems berücksichtigt und die Belichtung auf der Bildebene korrekt berechnet.

Avoidance of routing loops
(2009)
We introduce a new routing algorithm which can detect routing loops by evaluating routing updates more thoroughly. Our new algorithm is called Routing with Metric based Topology Investigation (RMTI), which is based on the simple Routing Information Protocol (RIP) and is compatible to all RIP versions. In case of a link failure, a network can reorganize itself if there are redundant links available. Redundant links are only available in a network system like the internet if the topology contains loops. Therefore, it is necessary to recognize and to prevent routing loops. A routing loop can be seen as a circular trace of a routing update information which returns to the same router, either directly from the neighbor router or via a loop topology. Routing loops could consume a large amount of network bandwidth and could impact the endtoend performance of the network. Our RMTI approach is capable to improve the efficiency of Distance Vector Routing.
This Thesis deals with the state of Customer Relationship Management (CRM) in companies and the opportunities that are offered by these. The motivation for this thesis results from the request to classify the value of CRM. Furthermore, we want to do a research on how far a CRM-System is able to support and improve company processes. In addition, we want to get an overview of possible conditions that are linked with such a system. For the use case the motivation follows from the opportunity to optimize inefficient processes. As a result, this thesis tries to present perspectives which can improve company processes; moreover conduce to a bigger value creation.
This thesis covers in detail with customer-related processes of the company Alere and its quality in terms of the prospective implementation of a CRM-System. As there are only a few standard requirements for the processes, it is not possible to make a statement about process quality. These circumstances need a tool that is able to fulfil specified requirements. This gap shall be closed by a CRM-System. If we want to close this gap efficiently we first have to research the actual customer-related processes with the aim to specify the new system requirements.
The thesis shall deliver an insight into the topic with the goal to show the advantages of a CRM-System. Additionally, the identification of weak points, based on the use case and the motivation follows. With these data we will optimize the customer-related processes based on the CRM-System functions. Several departments of the company have contact with the customers. Because of this fact the focus lies on documentation, central data storage and loss-free communication between customers and staff and among the staff. The thesis shall deliver different results. First of all, a catalogue of requirements for the customer-related processes which bases on the basics.
Furthermore, the modelling of the customer-related processes. In addition a catalogue of the weak points of the customer related processes and after that a specification of requirements for the CRM-System to optimize the customer-related processes.
Finally the thesis shall generate the modelling of the optimized customer-related processes. The last result the thesis shall deliver is the discussion and conclusion.
