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.
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.
Cloud-Computing ist aktuell ein besonderer Trend in der IT-Branche. ERP-Systeme sind in den heutigen Unternehmen ebenfalls nicht mehr wegzudenken. Durch die Analyse ausgewählter Literatur wird aufgezeigt, dass Cloud-Computing als Betriebsmodell für ERP-Systeme besonderer Untersuchung bedarf, da beim Zusammenspiel dieser Technologien noch unterschiedliche Herausforderungen geklärt werden müssen. Darauf aufbauend werden mit Hilfe von drei verschiedenen Praxispartnern Fallstudien zu deren Cloud-ERP-Lösungen erstellt, um in einem nächsten Schritt die theoretische Literatur mit den praktischen Ergebnissen zu vergleichen.
Ziel dieser Arbeit ist es mit Hilfe der Forschungsfragen, differenzierte Nutzenaspekte von Cloud-ERP-Lösungen aufzudecken und zu erklären, wie die Theorie mit praktischen Erfahrungswerten von Experten übereinstimmt. Durch die Fallstudien wird deutlich, dass sich die drei unterschiedlichen Cloud-ERP-Anbieter vor allem durch den Umfang ihrer Software und die Unternehmensgrößen der Zielgruppen im Markt differenzieren. Zusätzlich zeigt sich im Analyseteil und Fazit der Arbeit, dass über die in der Theorie identifizierten Nutzenaspekte hinaus, zusätzliche Nutzenaspekte durch die Kombination von Cloud-ERP-Lösungen generiert werden können und dass es aktuell schon eine spezielle Zielgruppe für Cloud-ERP-Lösungen gibt. Für die Zukunft bleibt abzuwarten, wie sich der Cloud-ERP-Markt weiterentwickeln wird und welche weiteren Funktionalitäten in die Cloud ausgelagert werden können, sodass sich On-Demand ERP-Systeme zu einer Konkurrenz von On-Premise-Lösungen entwickeln können.
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.
Procedural content generation, the generation of video game content using pseudo-random algorithms, is a field of increasing business and academic interest due to its suitability for reducing development time and cost as well as the possibility of creating interesting, unique game spaces. Although many contemporary games feature procedurally generated content, the author perceived a lack of games using this approach to create realistic outer-space game environments, and the feasibility of employing procedural content generations in such a game was examined. Using current scientific models, a real-time astronomical simulation was developed in Python which generates star and planets object in a fictional galaxy procedurally to serve as the game space of a simple 2D space exploration game where the player has to search for intelligent life.
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.
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.
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.
Development of an Android Application for the Recognition and Translation of Words in Camera Scenes
(2012)
This bachelor- thesis describes the conception and implementation of a translation software for the Android platform. The specific feature of the software is the independent text recognition based on the view of the camera. This approach aims to enhance and accelerate the process of translation in certain situations. After an introduction into text recognition, the underlying technologies and the operation system Android useful applications are described. Then the concept of the software is created and the implementation examined. Finally an evaluation is conducted to identify strengths and weaknesses of the software.
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.
