The successful design, implementation, deployment, and use of mobile software applications is rare. While many mobile apps are developed, few succeed. This design science research project builds and evaluates CrashApp™, a mobile application that connects lawyers and clients before, during, and after car accidents. The effective, widespread use of this app depends on satisfying the needs of three groups of stakeholders – the end-users (clients), the owners (lawyers), and the software developers. The research objective is to investigate the key differences among the three stakeholder groups on evaluation criteria for mobile app success. Evaluation strategies and methods are selected to collect data that measures each group’s satisfaction with the constructed application artefact. Research contributions are the identification of multiple stakeholder groups and the ability to design rich evaluation strategies that provide measures of application success. Practice contributions are the design and development of a useful mobile app that provides needed services to the client and effective client connections for the law firm to interact with the clients. The project produced an instantiation of the design artefact CrashApp™ mobile application, which was evaluated with a naturalistic evaluation approach, including the following methods and techniques: focus groups, focused surveys, usability surveys, and real life tests and assessments.

After trying Festival Speech Synthesis System, we decided to develop our own TTS framework, conducive to perform the necessary research experiments for developing good quality TTS for Indian languages. In most of the attempts on Indian language TTS, there is no prosody model, provision for handling foreign language words and no phrase break prediction leading to the possibility of introducing appropriate pauses in the synthesized speech. Further, in the Indian context, there is a real felt need for a bilingual TTS, involving English, along with the Indian language. In fact, it may be desirable to also have a trilingual TTS, which can also take care of the language of the neighboring state or Hindi, in addition. Thus, there is a felt need for a full-fledged TTS development framework, which lends itself for experimentation involving all the above issues and more. This thesis work is therefore such a serious attempt to develop a modular, unit selection based TTS framework. The developed system has been tested for its effectiveness to create intelligible speech in Tamil and Kannada. The created system has also been used to carry out two research experiments on TTS. The first part of the work is the design and development of corpus-based concatenative Tamil speech synthesizer in Matlab and C. A synthesis database has been created with 1027 phonetically rich, pre-recorded sentences, segmented at the phone level. From the sentence to be synthesized, specifications of the required target units are predicted. During synthesis, database units are selected that best match the target specification according to a distance metric and a concatenation quality metric. To accelerate matching, the features of the end frames of the database units have been precomputed and stored. The selected units are concatenated to produce synthetic speech. The high values of the obtained mean opinion scores for the TTS output reveal that speech synthesized using our TTS is intelligible and acceptably natural and can possibly be put to commercial use with some additional features. Experiments carried out by others using my TTS framework have shown that, whenever the required phonetic context is not available in the synthesis database., similar phones that are perceptually indistinguishable may be substituted. The second part of the work deals with the design and modification of the developed TTS framework to be embedded in mobile phones. Commercial GSM FR, EFR and AMR speech codecs are used for compressing our synthesis database. Perception experiments reveal that speech synthesized using a highly compressed database is reasonably natural. This holds promise in the future to read SMSs and emails on mobile phones in Indian languages. Finally, we observe that incorporating prosody and pause models for Indian language TTS would further enhance the quality of the synthetic speech. These are some of the potential, unexplored areas ahead, for research in speech synthesis in Indian languages.

The purpose of this work is the design and experimental verification usability testing methodology of mobile contactless NFC payments. Given that this is the very innovative and flexible region (m-commerce and the usability of mobile devices) we need to develop a methodology to adapt the methods and usability testing standards for the specifics of mobile devices. The benefit of this work is to link the usability and m-commerce and the creation of a methodology for mobile devices usability testing. This work can be beneficial for companies that decides to enter the mobile payments market (as for instance a firm MOPET CZ rather unexpectedly made with the mobito project) and also for companies that are already dealing with m-commerce. This work can be also useful as a matrix for creating own testing methodology for mobile devices, even for other purposes.

Representation of heritage via digital and online tools gains more attention from culture professionals and the general public. Mobile applications allow museums to reach wider audiences, make heritage more accessible for people with special needs and provide content in various forms. Catholic cathedrals, being the sites with great tourism potential and rich historical and cultural legacy, also create their mobile applications in several languages. This research aims to answer the question of how mobile applications contribute to the representation of the heritage of religious sites. The case studies are the mobile applications of Notre-Dame, Milan, Florence and Cologne cathedrals. The visual and textual content and the design of the applications are analyzed to explore how heritage meets religious and secular needs. As a result, it was possible to identify patterns used by the cathedrals' management and application developers when generating religious heritage content in this technologic framework. Besides, practical suggestions on improvement of the technical layout and narrative practices are made. Keywords: religious heritage, heritage representation, mobile applications, digital museum, tourism, museum communication, UNESCO 2

Many methods have been proposed for efficient storage of molecular hydrogen for fuel cell applications. However, despite intense research efforts, so far, the industrial parameters of 6.5% mass ratio and 62 kg/m3 volume density are still questionable though the results are obtained by either experimentally or via theoretical simulations on reversible model systems. Carbon-based materials, have always been regarded as the most attractive physisorption substrates for the storage of hydrogen. Theoretical and experimental studies on various model carbon systems, however, failed to reach the elusive goal. In this work, it is shown that insufficiently accurate carbon - hydrogen diatomic interaction potentials, together with the neglect and incomplete treatment of the quantum effects in previous theoretical investigations, led to misleading conclusions for the absorption capacities of different carbon materials. A proper account of the contribution of quantum effects to the free energy and the equilibrium constant for hydrogen adsorption suggest that the industry specifications can be approached in a graphite-based physisorption system. The theoretical prediction can be realised by optimising the topology, the cavity shape and the accessible surface of the carbon structures.
