In this bachelor thesis a tangible augmented reality game was developed, which should have a additional benefit compared to conventional computer or augmented reality games. The main part of the thesis explains the game concept, the development and the evaluation of the game. In the evaluation the flow-experience, as measurement for the games" amusement, was analysed with a user test and the developed game was compared with other smartphone games. Also augmented reality, tangible user interface and tangible augmented reality was introduced and the advantages and disadvantages was explained. The history of augmented reality was introduced 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.
This paper critically examines the Google Calendar. For this purpose, the offered functions of the core product are studied on privacy aspects. On one hand, it is identified, to which extent the product could infringe the users" privacy, on the other accuring risks are discussed. Furthermore, the functions in terms of their use for both, the service provider Google and for the user, are considered. A detailed analysis demonstrates the critical aspects, in which we have to decide between privacy and functionality. The identified solutions to minimize discussed risks of IT security mechanisms, are presented, discussed and analyzed in terms of their feasibility. Afterwards the individual solutions are summarized in a security concept and other requirements are explained. Finally, a Firefox-Addon which implements the described solution concept should be created, to resolve the existing weaknesses to the best of its ability. Ultimately, the functionality of the addon with technical implementation is illustrated in detail.
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.
Die wesentliche Zielsetzung der Bachelor-Arbeit war es, entlang der Anforderungen an DMS/WMS aus dem DOMEA-Konzept und aus dem Kommunalen Gebietsrechenzentrum Koblenz (KGRZ) verschiedene Systeme zu evaluieren. Weiteres Ziel war es, ein System, das die Anforderungen am besten erfüllt, zu identifizieren. Entlang der Evaluation wurde exemplarisch der Workflow des KGRZ untersucht, bewertet und ggf. angepasst. Des Weiteren wurde auf die Frage eingegangen, ob ein einheitliches System im Rahmen des Föderalismus nicht nur in Koblenz sondern auch Rheinland-Pfalz weit eingesetzt werden kann, oder ob ämterspezifische Lösungen vorteilhafter sind.
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.
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.
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.
Only little information is available about the diffusion of cloud computing in German higher educational institutions. A better understanding of the state of the art in this field would support the modernization of the higher educational institutions in Germany and allow the development of more adequate cloud products and more appropriate business models for this niche. For this purpose, a literature research on Cloud Computing and IT-diffusion will be run and an empirical investigation with an online questionnaire addressed to higher educational institutions in Germany will be performed to illustrate the state of the art of Cloud Computing in German higher educational institutions as well as the threats and opportunities perceived by employees of higher educational institutions data centers connected to the usage of the cloud.
In addition to that, different experts from universities and businesses will be interviewed to complete the knowledge and information collected through the online questionnaire and during the research phase. The expected results will serve to create a recommendation for higher educational institutions in Germany about either they should migration to the cloud or not and introduce a list of guiding questions of critical issues to consider before using cloud-computing technologies.
