In order to enhance the company’s appeal for potential employees and improve the satisfaction of already salaried workers, it is necessary to offer a variety of work-life balance measures. But as their implementation causes time and financial costs, a prioritization of measures is needed. To express a recommendation for companies, this study is led by the questions if there are work-life balance measures which have more impact on employee satisfaction than others, how big the relative impact of work-life balance measures on job satisfaction in comparison to other work and private life variables is, if there is a relation between the effectiveness of measures and their use and if there is a difference between the measures which are most important from the employees’ perspective and the companies’ offers.
These questions are formulated in eight research hypotheses which are examined in a quantitative research design with online survey data from 289 employees of fifteen different German companies. The formation of a hierarchy of the effectiveness of measures towards job satisfaction as well as the investigation of the relative impact in comparison to other variables is performed using a multiple regression analysis, whilst the differences between employees’ expectations and the availability of offers are examined with t-tests.
Support in childcare, support in voluntary activities and teambuilding events have a significantly higher impact on job satisfaction than other work-life balance measures, and their potential use is higher than the actual use which leads to the conclusion that there is yet potential for companies to improve their employees’ satisfaction by implementing these measures. In addition, flexible work hours, flexible work locations and free time and overtime accounts are the most important measures from the employees’ point of view and already widely offered by the surveyed companies. In general, the overall use of the available measures and the quantity of offered measures are more important with regard to job satisfaction than the specific kind of measure. In addition, work-life balance measures are more important towards job satisfaction for younger people.
Despite widespread plans of big companies like Amazon and Google to develop unmanned delivery drones, scholarly research in this field is scarce, especially in the information systems field. From technical and legal perspectives, drone delivery in last-mile scenarios is in a quite mature state. However, estimates of user acceptance are varying between high skepticism and exaggerated optimism. This research follows a mixed method approach consisting both qualitative and quantitative research, to identify and test determinants of consumer delivery drone service adoption. The qualitative part rests on ten interviews among average consumers, who use delivery services on a regular basis. Insights gained from the qualitative part were used to develop an online survey and to assess the influence of associated risks on adoption intentions. The quantitative results show that especially financial and physical risks impede drone delivery service adoption. Delivery companies who are currently thinking about providing a delivery drone service may find these results useful when evaluating usage behaviors in the future market for delivery drones.
Diese Arbeit beschreibt einen Ansatz zur webbasierten und GPU-unterstützten medizinischen Visualisierung. Der Schwerpunkt liegt auf der client-seitigen Ausführung von direktem Volumen-Rendering mittels WebGL und der Übertragung von medizinischen Datensätzen von Server zu Client. Die Motivation dieser Arbeit liegt vor allem in den neuesten Entwicklungen von Webtechnologien begründet, da es bisher nicht möglich war hardwarebeschleunigte 3D-Grafik direkt im Webbrowser darzustellen. Erst seit der Entwicklung der 3D-Grafik-Programmierschnittstelle WebGL besteht die Möglichkeit GPU-unterstütztes Volumenrendering im Browser-Kontext ohne den Einsatz zusätzlicher Software zu realisieren. Es wird ein webbasiertes Volumenrendering-System vorgestellt, das die Umsetzung von Volumen-Raycasting mit WebGL zur direkten Darstellung von Volumendaten in Echtzeit behandelt. Für die technische Umsetzung wurden das Google Web Toolkit und die Google App Engine als Infrastruktur verwendet.
Die weltweite Zugänglichkeit und umfangreiche Nutzung des Internets machen dieses Medium zu einem effizienten und beliebten Informations-, Kommunikations-, und Verkaufsinstrument. Immer mehr Menschen und Organisationen versuchen, diese Vorzüge durch eine eigene Website für ihre Zwecke zu verwenden. Als hilfreiches Mittel zur Optimierung von Webpräsenzen bewährte sich in den letzten Jahren der Einsatz von Web-Analytics-Software. Durch diese Software sind Websitebetreiber in der Lage, Informationen über die Besucher ihrer Website und deren Nutzungsverhalten zu sammeln und zu messen. Das angestrebte Resultat sind Optimierungsentscheidungen auf Basis von Daten an Stelle von Annahmen und wirkungsvolle Testmöglichkeiten.
Für den Bereich des E-Commerce existieren bis dato zahlreiche wissenschaftliche und praxiserprobte Hilfestellungen für Web-Analytics-Projekte. Informationswebsites hingegen werden trotz ihrer Wichtigkeit nur vereinzelt thematisiert. Um diesem Defizit entgegenzuwirken, hat Hausmann 2012 das Framework for Web Analytics entwickelt, welches dem Anwender ein hilfreiches Referenzmodell für sein Web Analytics-Vorhaben bietet. Diesen Ansatz weiter voranzutreiben ist das Ziel der Abschlussarbeit. Dazu wird mithilfe einer Literaturanalyse und einer Fallstudie das Framework validiert und ergänzt, sowie weitere Handlungsempfehlungen identifiziert. Als Ergebnis werden die wichtigsten Erkenntnisse dieser Forschung zusammengefasst und für den zukünftigen Gebrauch festgehalten.
This paper introduces Vocville, a causal online game for learning vocabularies. I am creating this application for my master thesis of my career as a "Computervisualist" (computer visions) for the University of Koblenz - Landau. The application is an online browser game based on the idea of the really successful Facebook game FarmVille. The application is seperated in two parts; a Grails application manages a database which holds the game objects like vocabulary, a Flex/Flash application generates the actual game by using these data. The user can create his own home with everything in it. For creating things, the user has to give the correct translation of the object he wants to create several times. After every query he has to wait a certain amount of time to be queried again. When the correct answer is given sufficient times, the object is builded. After building one object the user is allowed to build others. After building enough objects in one area (i.e. a room, a street etc.) the user can activate other areas by translating all the vocabularies of the previous area. Users can also interact with other users by adding them as neighbors and then visiting their homes or sending them gifts, for which they have to fill in the correct word in a given sentence.
In dieser Arbeit wurde die Realisierung einer mobilen Sicherheitslösung für Überwachungszwecke vorgestellt, welche unter Zuhilfenahme des staatlich geförderten Forschungsprojekts CamInSens entwickelt wurde. CamInSens soll erreichen, in überwachten Gefahrenbereichen die erhaltenen Video- und Sensorendaten so zu analysieren, dass Bedrohungen möglichst frühzeitig erkannt und behandelt werden können. Das Ziel dieser Arbeit war, auf Basis von verarbeiteten Daten aus CamInSens eine Interaktion und Visualisierung zu entwickeln, die bei einem späteren Praxiseinsatz mobilem Sicherheitspersonal dabei hilft, in Bedrohungssituationen fundierte Entscheidungen treffen zu können. Zu diesem Zweck wurde nicht nur eine Software implementiert, sondern auch eine Marktsichtung hinsichtlich geeigneter Geräte und einsetzbarer Softwarebibliotheken durchgeführt.
Virtual Goods + ODRL 2012
(2012)
This is the 10th international workshop for technical, economic, and legal aspects of business models for virtual goods incorporating the 8th ODRL community group meeting. This year we did not call for completed research results, but we invited PhD students to present and discuss their ongoing research work. In the traditional international group of virtual goods and ODRL researchers we discussed PhD research from Belgium, Brazil, and Germany. The topics focused on research questions about rights management in the Internet and e-business stimulation. In the center of rights management stands the conception of a formal policy expression that can be used for human readable policy transparency, as well as for machine readable support of policy conformant systems behavior up to automatic policy enforcement. ODRL has proven to be an ideal basis for policy expressions, not only for digital copy rights, but also for the more general "Policy Awareness in the World of Virtual Goods". In this sense, policies support the communication of virtual goods, and they are a virtualization of rules-governed behavior themselves.
This thesis deals with the distribution of large virtual networks to multiple physical hosts using the virtualization tools VNUML and EDIV. While VNUML is responsible for simulating the network, EDIV has its focus primarily on the distributiion. After a short explanation of basic terms and concepts from the field of network simulation, the two previously mentioned virtualization tools are described in detail. This starts in both cases with a detailed description regarding the proper installation and configuration, followed by a demonstration of the most important functions, such as starting or stopping a simulation. The creation of a suitable network scenario and the information scripts provided by EDIV are two further points described in this context. To use the presented possibilities of those tools in practice, an own network scenario is designed and distributed to several hosts, so that the different functions of EDIV can be shown and described accurately.

Diese Tatsache hat insofern negative Auswirkung, als dass es für die sozialen Sicherungen Gefahren birgt, nicht mehr finanziert werden zu können. Des Weiteren ist über einen langen Zeitraum mit einem Fachkräftemangel zu rechnen, sollte sich der Geburtenrückgang weiterhin fortsetzen.
In dieser Ausarbeitung wird der Zusammenhang zwischen dem Bildungsgrad der Frau und dem Anteil kindeloser Frauen und der Anzahl an Kindern untersucht. Sollte dabei ein Zusammenhang bestehen, so müssten vor allem Akademikerinnen den höchsten Anteil an Kinderlosigkeit und die niedrigste Kinderzahl je Frau aufweisen. Im Umkehrschluss müssten Frauen mit Hauptschulabschluss oder Frauen ohne Schulabschluss die niedrigsten Anteile an Frauen ohne Kinder und die höchsten Zahlen an Kindern je Frau vermelden.
Das Ziel dieser Bachelorarbeit ist es ein Schätzkonzept zu validieren, das im Rahmen eines Projektes auf der Universität Koblenz-Landau entwickelt wurde, um den Anteil kinderloser Frauen und die Anzahl an Kindern je Frau zu schätzen
Hybrid systems are the result of merging the two most commonly used models for dynamical systems, namely continuous dynamical systems defined by differential equations and discrete-event systems defined by automata. One can view hybrid systems as constrained systems, where the constraints describe the possible process flows, invariants within states, and transitions on the one hand, and to characterize certain parts of the state space (e.g. the set of initial states, or the set of unsafe states) on the other hand. Therefore, it is advantageous to use constraint logic programming (CLP) as an approach to model hybrid systems. In this paper, we provide CLP implementations, that model hybrid systems comprising several concurrent hybrid automata, whose size is only straight proportional to the size of the given system description. Furthermore, we allow different levels of abstraction by making use of hierarchies as in UML statecharts. In consequence, the CLP model can be used for analyzing and testing the absence or existence of (un)wanted behaviors in hybrid systems. Thus in summary, we get a procedure for the formal verification of hybrid systems by model checking, employing logic programming with constraints.
In the "Institut MTI Mittelrhein" the impact of training and experience on motion and motion planning in sports is examined. As a part of these investigations, the motion behaviour of a sports climber is analyzed on a sports climbing wall. The aim of this thesis is the segmentation and marker-based detection of the movement of a climber in video recordings. The segmented markers from each image are tracked by a tracking procedure over time. The motion tracks will be exported to the motion analysis software Simi Motion in a format suitable for further analysis.
Remote rendering services offer the possibility to stream high quality images to lower powered devices. Due to the transmission of data the interactivity of applications is afflicted with a delay. A method to reduce delay of the camera manipulation on the client is called 3d-warping. This method causes artifacts. In this thesis different approaches of remote rendering setups will be shown. The artifacts and improvements of the warping method will be described. Methods to reduce the artifacts will be implemented and analyzed.
Das allgemeine Erreichbarkeitsproblem in Stellen/Transitions-Netzen behandelt die Frage, ob eine bestimmte Zielmarkierung aus einer anderen Markierung erreichbar ist. Die lineare Algebra als Teilgebiet der Mathematik kann zur Beschreibung und Analyse von Petri-Netzen herangezogen werden. Jedoch stellen Kreise in Netzen bei der Erreichbarkeitsanalyse ein Problem für sie dar: ob für bestimmte Transitionen erforderliche Marken sofort, erst nach dem Durchlaufen bestimmter Kreise oder gar nicht zur Verfügung stehen, ist nicht erkennbar, hat jedoch unmittelbare Auswirkungen auf die Erreichbarkeit. Es gibt verschiedene Möglichkeiten, dieses Problem linear-algebraisch anzugehen. In dieser Arbeit werden vorhandene Verfahren sowie neue Lösungsansätze auf Basis der Reproduzierbarkeit der leeren Markierung diskutiert.
This thesis deals with problems, which occure when rendering stereoscopic contents. These problems are elaborated, simulated with the help of a program developed in this thesis and evaluated by a group of volunteers. Thereby it shall be determined, whether the errors are noticeable and how much they influence the 3D effect of the stereoscopic images. Each error is simulated using different camera assemblies and evaluated depending on the choosen assembly.
This work deals with the migration of software systems towards the use of the character set defined in the Unicode standard. The work is performed as a case study on the document-management-system PROXESS. A conversion process will be designed that defines the working-steps of the migration for the entire system as well as an arbitrary decomposition of the system into individual modules. The working-steps for each module can be performed chronologically independent of each other to a great extend. For the conversion of the implementation, an approach of automatic recognition of usage patterns is applied. The approach aims at searching the abstract syntax tree for sequences of program instructions that can be assigned to a certain usage pattern. The usage pattern defines another sequence of instructions that acts as an sample solution for that usage pattern. The sample solution demonstrates the Unicode-based management of strings for that usage pattern. By applying a transformation rule, the original sequence of instructions is transferred to the sequence of instructions exposed by the sample solution of the related usage pattern. This mechanism is a starting point for the development of tools that perform this transformation automatically.
Die Computergrafik befasst sich mit der Erzeugung von virtuellen Bildern. Im Bereich der 3D-Computergrafik werden die dargestellten Objekte im dreidimensionalen Raum beschrieben. Dazu bedient man sich diverser Generierungsverfahren. Einer dieser so genannten Renderer ist das Raytracing-Verfahren. Es erfreut sich in der Computergrafik wegen der erreichten Bildqualität bei ueberschaubarer Komplexität großer Beliebtheit. Dabei wird versucht, immer realistischere Ergebnisse zu erreichen. In der Vergangenheit wurde Raytracing deswegen beispielsweise um globale Beleuchtungsmodelle oder um reflektierende beziehungsweise um transparente Objekte erweitert. Dabei wurde aber ein wichtiger Punkt häufig vernachlässigt, welcher ebenfalls den Grad an Realismus deutlich erhöhen kann: die Kamera. Meistens geht man auch heutzutage von einem vereinfachten Lochkameramodell aus. Aus diesem Grund genügen solche Modelle nicht den Ansprüchen physikalisch-korrekter Renderingverfahren. Eine wirklich umfassend korrekte Abbildung von Szenen darf also nicht vernachlässigen, dass ein generiertes Bild durch ein Linsensystem noch einmal entscheidend beeinflusst wird. In dieser Arbeit wird deswegen ein physikalisch korrektes Kameramodell vorgestellt, welches die geometrischen Eigenschaften des Linsensystems berücksichtigt und die Belichtung auf der Bildebene korrekt berechnet.
UML models and OWL ontologies constitute modeling approaches with different strength and weaknesses that make them appropriate for use of specifying different aspects of software systems. In particular, OWL ontologies are well suited to specify classes using an expressive logical language with highly flexible, dynamic and polymorphic class membership, while UML diagrams are much more suitable for specifying not only static models including classes and associations, but also dynamic behavior. Though MOF based metamodels and UML profiles for OWL have been proposed in the past, an integrated use of both modeling approaches in a coherent framework has been lacking so far. We present such a framework, TwoUse, for developing integrated models, comprising the benefits of UML models and OWL ontologies
The STOR project aims at the development of a scientific component system employing models and knowledge for object recognition in images. This interim report elaborates on the requirements for such a component system, structures the application area by identifying a large set of basic operations, and shows how a set of appropriate data structures and components can be derived. A small case studies exemplifies the approach.
Dualizing marked Petri nets results in tokens for transitions (t-tokens). A marked transition can strictly not be enabled, even if there are sufficient "enabling" tokens (p-tokens) on its input places. On the other hand, t-tokens can be moved by the firing of places. This permits flows of t-tokens which describe sequences of non-events. Their benefiit to simulation is the possibility to model (and observe) causes and effects of non-events, e.g. if something is broken down.
