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.
In the age of Web 2.0 the internet as a platform to provide services or sell goods gained more attention in companies. Especially for customer support customer forums can be a useful tool for companies. By providing customer forums, companies can reduce their support costs dramatically. Nevertheless, it is often difficult for companies to measure the success of customer forums. In the research literature the determinants of success of customer forums have seldom been studied. The purpose of this bachelor thesis is to fill this research gap by applying the model of Lin and Lee to measure the success of online-communities on customer forums. In addition, metrics for measuring the success of this model are discussed. The discussion of this topic leads to the conclusion that the model of Lin and Lee is mostly applicable for customer forums, and provides a useful approach to measuring suc-cess both in theory and in practice. This could be demonstrated by the example of the 1&1 customer forum. The metrics that were found in the theoretical part were quite relevant in practice. Nevertheless, future research should focus more on monetary indicators to also make success of customer forums financially assessable.
This examination broaches the issue of an investigation that is supported by the eye-tracking technologie and uses the e-learn-system Compass. For this investigation, there was carried out an experiment to test participants if they recognize agreement errors in the subjekt-verb- congruence in german sentences. The idea for that came from an other survey, that was hold for the englisch language. The integration of the e-learn-system Compass intended the observation of the participants learning behaviour. The experiment was able to be evaluated and analysed by the software of the eye-tracker, that recorded all eye movements and created valuable data out of them. It was assumed to catch the participants eye movements such as fixations or regressions.
The result was very clear: errors in congruence betweet subject and verb were done often. Besides, the error-rate increases proportionally to the length of the sentence.
Customization is a phenomenon which was introduced quite early in information systems literature. As the need for customized information technology is rising, different types of customization have emerged. In this study, customization processes in information systems are analyzed from a perspective based on the concept of open innovation. The objective is to identify how customization of information systems can be performed in an open innovation context. The concept of open innovation distinguishes three processes: Outside-in process, inside-out process and coupled process. After categorizing the selected journals into three core processes, the findings of this analysis indicated that there is a major concentration on outside-in processes. Further research on customization in coupled and inside-out processes is recommended. In addition, the establishment of an extensive up-to-date definition of customization in information systems is suggested.
Ist es möglich, allein mittels VR-Headset bei Nutzern Immersion zu
erzeugen? Zur Beantwortung dieser Frage werden zwei Simulationen einer
Achterbahnfahrt ohne haptisches Feedback mittels der Unreal Engine
4.20.3 für ein HTC-Vive VR Headset entwickelt und implementiert. Die
zweite Simulation unterscheidet sich von der ersten durch die Darbietung
außergewöhnlicher Ereignisse während der Fahrt, für die vermutet wird,
dass sie das Immersionserleben verstärken. Elf Probanden nahmen an der
Untersuchung teil. Die Auswertung eines Fragebogens zur Erfassung der
Intensität der Immersion und der Antworten auf offenen Fragen zeigt, dass
Immersion in beiden Simulation erfolgreich erzeugt werden konnte. Manche
Merkmale der Simulation vertieften bei einzelnen Probanden das immersive
Erleben, bei anderen dagegen nicht. Die Bedeutung der Ergebnisse
und Optimierungsmöglichkeiten für künftige Studien werden diskutiert.
In the last few years, information technology experienced a great increase. People and Enterprises are able to exchange information through the development of the Web 2.0 to the Social Web. Social Networks like Facebook or Xing, blogs from known and unknown people or the many discussion forums are common platforms where people have the opportunity to share and exchange information. Enterprises and people have to accept this fact and development. The reputation is also influenced by the overabundance of information. The result of this development is the digital reputation, which extend the entire reputation. Everyone who is looking for an order or a job can assume that his orrnher name will be "googled", whether he or she is a part of an internet branch or not. Every information is available through search engines. Just a quick look at the Facebook or Xing profile is needed to get a brief impression of someone. The communications expert Klaus Eck said that someone who takes the internet seriously will get a benefit for the development of his digital reputation. This research work will show you through a self made questionnaire what is seen as positive and negative influences on the reputation in Social Networks and how the digital reputation impacts the entire reputation.
This thesis deals with the question of which success factors apply to social media marketing. German start-up companies are examined for this purpose. The investigation is based on ten semi-structured expert interviews, which are evaluated using a qualitative content analysis. The results show that there are many success factors and that companies proceed differently in many areas when implementing social media marketing measures. Important success factors are a tailor-made, company-specific social media strategy with a clear formulation of goals, integration of social media marketing into the corporate strategy, openness to new social media trends, credibility and reputation, compliance with data protection, the correct handling of criticism, use of social media as a market research tool and a long-term social media strategy. However, the significance of the results should not be overestimated, since this is a qualitative study with a limited range and only examines individual cases. Further research on the success factors could be based on quantitative studies or group discussions in which experts or users or customers are interviewed. Another possibility is the qualitative examination of the user-generated content.
The present work starts with an introduction of methods for three-dimensional curve skeletonization. Different kinds of historic and recent skeletonization approaches are analysed in detail. Later on, a state-of-the-art skeletonization algorithm is introduced. This algorithm deals as a basis for the own approach presented subsequently. After the description and definition of a new method improving the state-of-the-art algorithm, experiments are conducted to get appraisable results. Next, a ground truth is described which has been set up manually by humans. The human similarity evaluations are compared with the results of the automatic computer-based similarity measures provided by the own approach. For this comparison, standard evaluation criteria from the field of information retrieval have been used.
This thesis describes the implementation of a Path-planning algorithm for multi-axle vehicles using machine learning algorithms. For that purpose, a general overview over Genetic Algorithms is given and alternative machine learning algorithms are briefly explained. The software developed for this purpose is based on the EZSystem Simulation Software developed by the AG Echtzeitysteme at the University Koblenz-Landau and a path correction algorithm developed by Christian Schwarz, which is also detailed in this paper. This also includes a description of the vehicle used in these simulations. Genetic Algorithms as a solution for path-planning in complex scenarios are then evaluated based on the results of the developed simulation software and compared to alternative, non-machine learning solutions, which are also shortly presented.
