Due to the incorrect allocation management and the continuous increase of internet-capable devices, IPv4-adresses are nearly exhausted. For this reason and because of new requirements demanded by the technique of the internet the IPv6-protocol has been developed. The IPv6-protocol provides a larger adress space and will gradually replace the IPv4-protocol. However, the routing-protocols have to be adapted to the new internetprotocol. This paper will introduce and analyse the dynamic Routing-Information-Protocol RIPng which in itself is an inter-gateway protocol (IGP). The routers inside the network can exchange information about their different connections over this protocol. Furthermore, this paper will explain the basics of the IPv6-protocol, of the used protocol-algorithm as well as of the RIPv2-protocol. In the practical part of the paper the Counting-to-Infinity-Problem and some attributes of RIPng will be reviewed under the IPv6-protocol.
API migration refers to the change of a used API to a different API in a program. A special case is called wrapper-based API migration. The API change is done without touching the program but the old API is reimplemented by means of the from now on used one. This so called wrapper has the interface of the reimplemented API but uses the implementation of the new one.
This is an interesting approach because the wrapper can be used in each program, which uses the old API.
To make this approach reproducible we study a ranking-based method for implementing a wrapper, where we always implement the method with the highest priority depending on failing test cases. Thus, we can reconstruct each implementation step.
We first develop an infrastructure to run and log test suites of Java projects that use an API, which we want to change.
We then build a wrapper for a given API using the ranking-based approach.
In this thesis we exercise a wide variety of libraries, frameworks and other technologies that are available for the Haskell programming language. We show various applications of Haskell in real-world scenarios and contribute implementations and taxonomy entities to the 101companies system. That is, we cover a broad range of the 101companies feature model and define related terms and technologies. The implementations illustrate how different language concepts of Haskell, such as a very strong typing system, polymorphism, higher-order functions and monads, can be effectively used in the development of information systems. In this context we demonstrate both advantages and limitations of different Haskell technologies.
Software integration is an engineering task where image-based approaches are still considered slow and error-prone. In this thesis, we apply image-based software integration to the domain of online Poker systems. That is, we implement the poker expert system PokerBot which can play online. We use the method of screen scraping to capture the screen information needed to interact with the Poker server. The consequent use of Template Matching leads to an efficient implementation. Substantial e ort was also addressed to the artificial intelligence aspects of PokerBot. The purpose of AI is here to mimic human playing style by translating a well-documented Pokerguide into formalized, executable language.
Potential vermögender Kunden

This bachelor thesis deals with the potential of wealthy clients in the private banking sector, as well as with financial services offered in this domain. For this purpose a comparison of the international potential in the German-speaking world was conducted which was ascertained with the help of statistical series.
The reference period for this comparison extends over thernyears from 2000 to 2009. Especially in this time period one was able to notice capital restructuring due to the finance crisis and its impacts. The results out of the analysis of the changing potential are then used to find possibilities of reorganizing offered financial services in the private banking sector. While doing so, the achievement of a high service level has the highest priority as this is the main reason for customers to remain with a certain bank. In addition to that this thesis also mentions new possibilities concerning the banking sector as well as consequences of different models of consultant payments.
Das Zeitfenster ab 1964 bis heute verzeichnet einen Geburtenrückgang. Diese Tatsache hat insofern negative Auswirkung, als dass es für die sozialen Sicherungen Gefahren birgt, nicht mehr finanziert werden zu können. Des Weiteren ist über einen langen Zeitraum mit einem Fachkräftemangel zu rechnen, sollte sich der Geburtenrückgang weiterhin fortsetzen.
In dieser Ausarbeitung wird der Zusammenhang zwischen dem Bildungsgrad der Frau und dem Anteil kindeloser Frauen und der Anzahl an Kindern untersucht. Sollte dabei ein Zusammenhang bestehen, so müssten vor allem Akademikerinnen den höchsten Anteil an Kinderlosigkeit und die niedrigste Kinderzahl je Frau aufweisen. Im Umkehrschluss müssten Frauen mit Hauptschulabschluss oder Frauen ohne Schulabschluss die niedrigsten Anteile an Frauen ohne Kinder und die höchsten Zahlen an Kindern je Frau vermelden.
Das Ziel dieser Bachelorarbeit ist es ein Schätzkonzept zu validieren, das im Rahmen eines Projektes auf der Universität Koblenz-Landau entwickelt wurde, um den Anteil kinderloser Frauen und die Anzahl an Kindern je Frau zu schätzen
The advantage of virtual networks is to test routing-algorithms or distributed software in an easy-to-use, cheap and well-arranged way. Optimized Link State Routing (OLSR) and Babel are two modern routing-algorithms for mobile ad-hoc networks that distinguish faulty links from good link connections in their routing process. Typically virtual networks provide nearly perfect link connections without any network traffic disruptions. The Traffic Control (tc) tool is able to manipulate connections in terms of delay and packet loss.
In this bachelor thesis virtual network scenarios are created with VNUML and Qemu and manipulated with tc in order to analyze the behavior of ad-hoc routing algorithms like Babel and OLSR. The behavior of well-known TCP congestion control algorithms, e.g., TCP Vegas and TCP Reno are analyzed, too.
The principles of project management are due to the influences of economic conditions and technological development in transition [Wills 1998 & Jonsson et al. 2001]. The increasing in-ternationalization, shortened time to market, changing labor costs and the increasing involve-ment of professionals distributed geographical locations are drivers of the transformations of the project landscape [Evaristo/van Fenema 1999]. Resulting from this, the use of collabora-tive technologies is a crucial factor for the success of a project. [Romano et al. 2002]. Previous research on the use of collaborative technologies for project management purposes focuses especially the development of model-like, universal system architectures to identify the requirements for a specially designed collaborative project management system. This thesis investigates the challenges and benefits that arise when an organisation imple-ments business software for the purpose of collaborative project management.
Within the scope of this bachelor thesis, a survey targeting the alumni of the Department 4: Computer Science of the University of Koblenz-Landau was planned, realized and evaluated. The goal was to support the Task Force Bachelor Master that was in charge of the re-accreditation process of the study courses. At first, the theoretical fundament of the survey design was acquired via desk research. Moreover, the analysis of past surveys of similar character lead to getting an impression of the requirements. Under consideration of recent changes, a survey prototype was created and improved following the insights from a pre-test. Using the open source tool LimeSurvey, the final version was implemented. The platform was used as the technical basis of the survey. The recipients included members of alumni clubs as well as recent alumni from the last years.
The survey lead to insights about the satisfaction of the alumni with their study course and the study situation in general. Furthermore, the opinion regarding two new master courses, E-Government and Web Science, was requested. The feedback from four of the study courses was enough to give significant results, for the other five courses it was only possible to interpret the general statements. All in all, there was a high rate of satisfaction with the studies.
Additionally, it was possible to collect suggestions for improvements and criticism. The main topics were internationality, emphasis on study topics, freedom of choice/specialization and relevancy to practice. As a result of the survey, a recommendation was verbalized, that should lead to an improvement in quality and need of the teaching in the Department 4: Computer Science in combination with the detailed results.
Especially e-government projects have a complex stakeholder structure: governments, businesses, non-profits and private stakeholders in different forms and roles are involved or affected by e-government projects. Consequently, the success of ICT projects critically depends on the integration of different stakeholder groups in the design processes of e-government solutions. In this context, stakeholder participation is sought therefore useful initiatives like open government and good governance drive this process forward. Although it is important to analyze the objectives, expectations and power characteristics of project participants and project stakeholders, the determinations of the stakeholder groups through a so called stakeholder analysis are insufficiently methodically developed.
The aim of this bachelor thesis is to pick up the stakeholder theories, stakeholder participation theories, stakeholder analysis and transfer it to an administrative level as well as to check their applicability. This will be done by explaining and systematizing appropriate procedures for the classification and mapping of stakeholder groups, through well-known stakeholder theories of Freeman, Mitchel and Rowley. In order to generate recommendations for future e-government projects, the application of stakeholder theories in two e-government projects with stakeholder involvement will be reviewed. It is also important to work out how stakeholder groups can be actively involved in the developmental processes in concrete e-government projects by using Web 2.0 possibilities. The role of Web 2.0 applications as an additional channel of communication and participation tool will be presented and evaluated.
The result is a guide, which supports successful participation of stakeholders in projects, by analyzing the process for stakeholder identification, stakeholder grouping and prioritization and showing instructions and benefits for using Web 2.0.
