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.
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.
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.
With the reaccreditation of the degree programs in the department of computer science at the University of Koblenz-Landau new trendsetting degree programs will be offered. For further planning and design of the individual degree programs the opinion of the students is a considerable indicator. Information about the new degree programs aren"t available during the accreditation process. Students have an interest in knowing about the new degree programs and the new examination regulation and therefore being part in the decision process would be desirable. The concept of e-participation is an opportunity to satisfy this need. It offers the possibility to discuss topics of the accreditation and to bring in own ideas and opinions into the decision process. This bachelor thesis describes an e-participation project at the University of Koblenz-Landau about the accreditation of the degree programs of the faculty of computer science. By using the reference framework of Scherer and Wimmer (2011) the project will be carried out. Furthermore the accreditation process will be modeled to get a better understanding of the whole process and to identify the possibilities for e-participation project integration. The results of this project are going to be covered by an online survey about the e-participation platform. Using the results of the survey and the experiences gained after the project recommendations are given for further e-participation projects. Moreover the reference framework of Scherer and Wimmer (2011) will be analyzed critically.
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.
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.
Activity recognition with smartphones is possible by using its internal sensors without using any external sensor. First of all, previous works and their techniques will be regarded and from these works an own implementation for the activity recognition will be derived. Most of the previous works only use the accelerometer for the activity recognition task. For this reason, this bachelor thesis analyzes the benefit of further sensors, such as the magnetic field, the linear acceleration or the gyroscope. The activity recognition is performed by classification algorithms. Decision Tree, Naive Bayes and Support Vector machines will be used. Sensor data of subjects will be collected and saved by using an own developed application. This data is needed as training data for the classification algorithms.
The result is a model which represents the structure of the data. To validate the model, a test dataset will be used which is different from the training dataset. The results confirm previous works which indicated that the activity recognition task is possible by only using the accelerometer. Orientation, gyroscope and linear acceleration cannot be used for all problems of the activity recognition. Apart from that, the Decision Tree seems to be the best classification algorithm if the model has no training data of the current user.
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.
