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.
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.
Parallelmanipulatoren, welche den Stewartmechanismus nutzen, ermöglichen die präzise Ausführung von Aufgaben in einem begrenzten Arbeitsraum. Durch die Nutzung von sechs Freiheitsgraden wird eine hohe Flexibilität der Positionierung erreicht. Die robuste Konstruktion sorgt zudem für ein sehr gutes Verhältnis von Gewicht zu Nutzlast.
Diese Bachelorarbeit befasst sich mit der Entwicklung einer flexiblen Softwarelösung zur Ansteuerung einer Stewartplattform. Dies umfasst ein Modell der Plattform, welches zu Testzwecken dient. Es werden zunächst die mathematischen Grundlagen der Inversen Kinematik erarbeitet aufbauend auf einem zuvor definierten Bewegungsmodell. Es folgt die Entwicklung einer generischen Architektur zur Übermittlung und Auswertung von Steuerkommandos vom PC. Die Implementierung geschieht in C und wird in verschiedene Module aufgeteilt, welche jeweils einen Aufgabenbereich der Positionskontrolle oder der Hardwarekommunikation abdecken. Es wird zudem eine graphische Nutzeroberfläche vorgestellt, über die man die Position der Plattform manuell verändern kann. Eine automatische Ansteuerung wird im folgenden Anwendungsbeispiel beschrieben, wo die Plattform mit frequentiellen Beschleunigungswerten einer Achterbahnsimulation beliefert wird.
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.
This thesis addresses the implementation of a particle simulation of an explosion. The simulation will be displayed via ray tracing in near real time. The implementation makes use of the openCL standard. The focus of research in this thesis is to analyse the performance of this combination of components.
The measurement of the benefits of collaborative technologies is a challenge caused by sociological influences on these systems. In this work, the introduction of a collaborative system into an existing IT environment is examined, so that a value can be identified for the company. The analysis of frameworks has shown that the benefits can be reaped through better management and organization of in-company resources and optimization of the underlying process.
The goal of this Bachelor thesis is to implement and evaluate the "Simulating of Collective Misbelief"-model into the NetLogo programming language. Therefore, the model requirements have to be specified and implemented into the NetLogo environment. Further tool-related re-quirements have to be specified to enable the model to work in NetLogo. After implementation several simulations will be conducted to answer the research question stated above.
The E-Government research area has gained in importance in Europe and specially Germany in the last few years, causing the number of researchers, institutes and publications to increase rapidly. This makes it difficult for outsiders to get an overview of the relevant actors in the E-Government field. This issue can be addressed by implementing a research map for the E-Government field, where all relevant actors and objects and their information are shown on the map according to their location. In order to give a complete overview, information which was valid at a certain time in the past needs to be available on the research map. This can be only achieved if the contents of the research map are historicized. This means that a new version of an object needs to be created and saved in the database, if changes occur to the object. Older versions need to be retained on the database, so that the user is able to navigate the website based on temporal information. Past experience has shown that the temporal aspects of historicization should be managed and planned during the conceptual phase of the website rather than during implementation. This Bachelor thesis proposes a concept for the E-Government research map which includes the modeling of relevant temporal dimensions needed to historicize the contents of the research map.
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.
