    In this paper, we present an investigation of the Portuguese research on e-government. Bibliometric techniques are used to explore all the documents published by researchers affiliated to Portuguese institutions from 2005 to 2014 and listed in the Scopus® database. Research production, impact, source types, language used, subject areas, topics, scopes, methods, authors, institutions, networks, and international cooperation are analysed and discussed. We conclude that so that Portuguese research on e-government can evolve, more researchers should be involved, international cooperation should be developed, and more attention should be given to the study of the reasons behind the very good results of the country in the provision of e-government services, as measured by the international rankings. By establishing the evolution and current standing of e-government research in Portugal and exploring the ways forward, our conclusions may prove useful to e-government researchers, research managers, and research policy makers. © Copyright 2016 Inderscience Enterprises Ltd

    The availability of sophisticated mobile applications on many platforms constitutes a challenging task. In order to cover the most relevant mobile operating systems and make the best use of their underlying features, the native development on the target platform still others the most diverse possibilities. Aside from the most widely spread mobile operating systems - namely Android and iOS - the Windows Phone platform oters a unique design language and many developer tools and technologies for building Windows Store apps. Making use of the capabilities of modern smartphones enables the development and use of desktop-like applications. The built-in sensors, cameras and powerful processing units of such a device other a versatile platform to build against. As a result, many mobile applications and technologies have emerged. However, information on profound insight into the development of such an application is hard to find. In this work, the development of AREA on the Windows Phone 8.1 platform is presented. AREA is a location-based mobile Augmented Reality engine and already available on Android and iOS. By porting the engine to yet another mobile platform, more third-party mobile business applications can integrate AREA and make use of its efficient and modular design. This work also points out the differences in implementation between the Windows Phone version and its counterparts on Android and iOS. Insights into the architecture and some references to the mathematical basis are also provided

    Mobile devices take in more and more space in our lifes and as tinnitus becomes a much more widespread disease, science started to develop treatment strategies. One of those treatment strategies is ’auditory training’ and with this strategy in mind a game concept with spatial audio was developed to provide an easily available ambulant help for chronic tinnitus patients. In the course of this thesis a seperate game only using spatial audio is developed on mobile iOS devices and in a study it is evaluated how good spatial audio can work on different mobile platforms. At the end of thesis the work is summarized and improvements in the game are displayed for further use in the above mentioned game scenario

    Smartphones were originally mainly used for making phone calls and playing games, but as they become more powerful and are equipped with a wide variety of sensors new use cases become interesting. One of these use cases is sleep monitoring, which is interesting for many different research areas. The goal of this bachelor thesis is to develop a sleep monitoring framework for the Android platform which can be used easily by third party applications. The framework takes care of detecting sleep related events like snoring and movement as well as monitoring the ambient light during the night. Additionally, a demo application is developed to demonstrate the functionality of the framework and to highlight some best practices regarding Android background services as they are essential for monitoring sleep

    This theses is conducted in cooperation with BSH Hausgeräte GmbH. The target is the investigation of the applicability of Android as an operating system for home appliances, specifically for ovens. In order to draw conclusions in regard of applicability, three major topics will be investigated. For a start, the performance of Android running on moderate target hardware will be analysed. The focus lies on graphics, since a high quality graphical user interface is most likely to be the crucial point in terms of performance. Providing a smooth and responsive graphical user interface is decisive for a satisfying user experience. Furthermore, originating from the mobile domain, Android requires an array of modifications prior to being embedded into an oven. The goal is to identify these potential aspects that need modification and give appropriate solutions, thus also providing an estimate of the required effort for the embedding process. Finally, potential inter-process communication mechanisms will be investigated with the objective to identify the most eligible method(s) for the communication between an Android application and the underlying oven hardware

    Tinnitus is a prevalent disease that mainly states a big mystery to all kinds of scientific faculties and causes enormous costs due to further research. An initial assumption of the disease was the coherence of Tinnitus with a worse spatial hearing ability of the patient. With the assistance of mobile devices, it is the aim of this thesis to realize a mobile web application that allows it to draw conclusions that might support this theory in an easy available and ambulant way. The application is created as a game that has its focus on spatial hearing. The thesis depicts the used Application Programming Interfaces and names possible improvements

    Das im März 2014 vorgestellte Betriebssystem Android Wear, welches speziell für Smartwatches angepasst wurde, bietet Entwicklern neue Möglichkeiten ihre bisherigen mobilen Anwendungen um eine Android Wear Anwendung zu erweitern. Im Rahmen dieser Arbeit wird ein Framework konzipiert und realisiert welches ermöglicht, mit einer Android Wear Smartwatch zu kommunizieren und Zugriff auf die Sensoren der Uhr zu erhalten. Durch die Kommunikation zwischen Smartphone und Smartwatch soll in regelmäßigen Abständen auf den Herzfrequenz-Sensor der Uhr zugegriffen werden und die gemessene Herzfrequenz an das Smartphone übertragen werden. Zusammen mit der erhobenen Herzfrequenz werden weitere Attribute wie Standort, Uhrzeit und aktuelle Aktivität des Nutzers gespeichert, um so eine in der Anwendung möglich Auswertung durchzuführen. Dies soll ermöglichen, dass beispielsweise Ärzte ihre Patienten, die mit einer Android Wear Smartwatch ausgestattet sind, durch eine regelmäßige Abfrage zu untersuchen

    Von chronischen Tinnitus betroffene Menschen müssen jeden Moment mit einem Geräusch leben, welches auf keine physikalische Quelle zurückzuführen ist. Dieses Leiden kann sogar zu Depressionen oder Arbeitsunfähigkeit führen. Die Erforschung von Tinnitus steht noch am Anfang und es existiert kein Heilmittel. Lediglich längerfristige Therapien und Trainings können den Betroffenen helfen zu lernen mit ihren Ohrgeräuschen zu leben. Im Institut für Datenbanken und Informationssysteme der Universität Ulm wurde die mobile Anwendung "Track your Tinnitus" entwickelt mit deren Hilfe die Tinnitusintensität über den Tagesverlauf hinweg vom Betroffenen aufgezeichnet werden kann. Um diese Anwendung zukünftig um einen Gehörtrainingsaspekt zu erweitern wird in der vorliegenden Arbeit eine mobile Anwendung für Windows Phone zur auditorischen Stimulation von chronischen Tinnituspatienten vom Konzept bis zu einem lauffähigen Prototypen erarbeitet. Dabei muss der Benutzer ein oder zwei Tiergeräusche, welche mittels virtuellem surround sound aus einer zufälligen Richtung wiedergegeben werden, orten. Dazu kann sich der Benutzer drehen, um das Geräusch vor sich zu positionieren um anschließend ein "Foto" des gehörten Tieres zu machen. Die benötigte Zeit, sowie die Abweichung zum Geräusch werden zur Laufzeit in Logfiles dokumentiert. In einer Studie wurde der Einfluss der gewählten Geräusche auf die Präzision und die benötigte Zeit untersucht. Dabei wurde festgestellt, dass sich die Anzahl der Geräusche nicht signifikant auf die Zeit oder Präzision auswirken. Jedoch wurde eines der verwendetes Geräusche signifikant präziser geortet, als das andere. Somit wurde gezeigt, dass die Geräuschauswahl für zukünftige Implementierungen des Trainingsmoduls der "Track your Tinnitus" Anwendung eine sehr wichtige Rolle spielt
