TV Broadcasting for Mobile Devices in Denmark
A lot of attempts to implement mobile TV broadcasting were made worldwide. In 2008, DVB-H has been seen as the choice for European market with a strong back from European Union and Nokia. Three years have passed and there is zero success with DVB-H across European countries. Boxer A/S, which is the commercial gatekeeper of 4 MUXes in Denmark, dedicated MUX6 for DVB-H, but have never started broadcasting mobile TV, even with the successful trials.
The deadline was extended till 2013, along with opportunity to change broadcasting standard. In this project, extensive research on available standards was concluded; existing broadcasting networks were taken into account as possible success factor for one or another standard, as well as the fact, that some standards are being recommended or promoted by the governmental institutions and other stakeholders. DAB networks cover up to 90 percent of Denmark population, the fact that DMB is based on DAB makes DMB very attractive mobile TV broadcasting standard. One the other hand, DVB-T2 Lite is being extensively promoted as the future of European mobile TV.
Results show that DMB has all the advantages – existing semi-successful implementations in South Korea, chipsets and already built networks – and therefore could be the choice. But then again, there are no sustainable business models in mobile TV market and this could again stop development of mobile TV in Europe no matter which standard would be implemented.

The Emergence of Information-Centric Networking
AN ANALYSIS OF THE BARRIERS TO A TRANSITION OF THE CURRENT INTERNET ARCHITECTURE TO AN ICN ARCHITECTURE
It is evident that there are problems in the current Internet architecture and researchers have showed that information-centric networking (ICN) is a possible solutions to these problems - but there are some huge socio-technical barriers in deploying ICN.
In this paper we outline the possible barriers to a transition of the Internet from the current host-centric paradigm to an information-centric paradigm.
We use transition theory by Geels and Schot (2007) as our main theoretical framework for analysing primary data gathered from three inter- views with important actors in the inter-networking field.
The analysis shows that there are different barriers in the deployment of ICN and from a transition perspective it can be seen that certain circumstances prevent a proper institutional design, which is needed to affect the existing regime. One way to enable proper institutional design is to create more economic incentives for adopting ICN.

Conflicting Interests within the Symbian Consortium
THE DOWNFALL OF SYMBIAN, EXPLAINED FROM A STANDARDIZATION PERSPECTIVE
This is a research of the different standardization interests within the Symbian consortium and an analysis of the effects of these. We depict the reasons behind the extinction of Symbian and outline how they can be explained from a standardization point of view. By the use of Kvale’s theory of qualitative data gathering and a thorough theoretical analysis we conclude that there were indeed different interests in Symbian, and by analyzing them from a standardization perspective it is revealed that imbalance in the ecosystem leadership has had a negative impact on Symbian’s ability to innovate and compete on the mobile platform market. Especially one partner indirectly took control of the interfacing standards in Symbian, which resulted in knowledge depreciation and lock-in situations that complicated Symbian’s ability to pursuit the changing demands.

Second Screen: Content and User Interaction
The Second Screen is a recent concept that allows linking online content, displayed on a Second Screen device, with the broadcast content displayed on the TV set screen. While most of the current Second Screen solutions do not rely on the broadcast as online content provider, this project takes a different approach where the br oadcaster provides both online
content and synchronisation data, used to link content on both screens. The reason of this choice is the high quality and relevance of the online content provided by the broadcaster.
However, the main questions remains: Which is the most suitable content to display on the Second Screen? How to present it?
And how to synchronise it with the broadcast content? To answer these questions, the news TV genre was chosen as an illustrative example that might benefit from a second screen. By conducting a research covering different Second Screen aspects and by developing a proof of concept application, it has been possible to identify that short facts , pictures
and graphs are the most suitable companion content while watching news, while longer articles and
audio-visual content are more suitable for deferred consumption.
In addition, the timeline concept proved to be very valuable for improving the Second Screen experience. From the technological perspective, WebSocket technology was able to provide a seamless inter-device synchronisation.

Mobile Mind State Detection Services
This project was dedicated to present the design, implementation and evaluation of mind state detection services, which allow brainwave signals, measured by low-cost wireless electroencephalography (EEG) headsets, to be read by mobile phone applications on smartphones.
The main aim was to analyze potential innovative solutions for usage with combination of modern smartphones and wireless brainwave-reading headsets. A significant part of this project was focusing on an analysis of the future implications, if hardware capability of reading the users’ brainwaves could be a standard equipment on a smartphone in a foreseeable future. To demonstrate the capabilities of wireless EEG headsets in combination with smartphones, authors presented a prototype recommender system that can compute a music playlist based on a smartphone user’s current mood. Such application could be useful for self-analysis and mental improvements

An HTML5-based Web Magazine Publishing System
Many companies, organizations and institutions, need to communicate with their customers, subscribers or partners through web magazines. As they are not always willing to invest too much on it, their web magazines lack sophisticated look and usability cross devices, compared to commercial ones.
This project aims to develop a web magazine publishing system that allows them to manage their content and publish it in form of web magazines that have professional look and usability. Adopting the Scrum agile development methodology and using Ruby on Rails framework to implement the content management side and the Treesaver framework to render the magazines, the project could cover most of the required features and achieve internship learning objectives and goals.

Mobile Interaction with Interactive Out-of-Home Media – A User Study
The presented project investigates how the interaction of mobile devices with Out-of-Home media could be improved from a user’s perspective.
More specific, it explores how the process of establishing a connection between a poster and smartphone can be improved, and if an improved method of interaction would result in an increase in users’ willingness to interact with Out-of-Home media.
To answer these questions, a user study has been conducted. The study consists of seven qualitative interviews, a quantitative survey and a user test that is comparing different methods of interaction between a poster and a smartphone.
Alternative solutions using Near-Field Communication, image recognition and push messages were being discussed and tested with the user.
The project is taking the viewpoint of advertisers, who would like to increase the interaction with posters.
Hence, a list of recommendations for future implementation of interactive Out-of-Home campaigns will arise as a result of the project.

HbbTV Business Model
The main goal of this project is to investigate a viable business model for Hybrid Broadband Broadcast Television (HbbTV) and how this standard can be widely adopted in the Danish market. HbbTV is a broadcast driven standard that combines broadcasting services with the possibilities provided by the connected TV in a transparent and fluid way for the viewers, leading to more interactivity with broadcasting contents.
Investigating adoption and market opportunities for new technology requires analysis of different issues: drivers and barriers of the technology, factors that contribute to the rate of adoption, different issues with regulation and digital right management (DRM), technology penetration rate, user behaviour and initial market condition. Our project defines all these concerns.
Investigating a viable business model for new technology would require an analysis of different interrelated components of business model. Furthurmore our project describes different components of business model for HbbTV, which are Service design, Organization design, Technology design and Finance design.

'Discover a book' recommendation portal
Scope of the thesis is to design and test a new approach for book recommendation portal. The purpose of the project is to examine, how users react to the different way of book recommendation, which is based on presenting small piece of the story from the book itself without confronting user with name of the author, book title or general description.
This approach assumes to investigate if accuracy of recommendations in already existing recommendation portals based on the different algorithms and already verified procedures is effective enough to provide user satisfaction. To answer these questions it is planned to do few stages of iterations and user testing.
The assumptions will be also well-funded by the literature study and problem analysis. Part of the project will be also creating of concept of such a recommendation portal. Motivation for this project is to build an innovative book recommendation system based on the random book browsing, like people used to do in libraries and bookshops.

Brainwaves as Access Control
The Mobile Mind State Detection Services project has been continued by Juris Klonovs and Christoffer Kjeldgaard Petersen in a degree project that utilizes brainwaves as unique identification of users.
Since brainwaves are unique, they can be used for high-security authentification of users, e.g. for access control. This video demonstrates how the system works:
The aim of this work is to investigate the possibilities to build a mobile biometric authentication system based on electroencephalogram (EEG). The objectives of this work include the investigation and identification of the most feasible feature extraction techniques and how these features can be used for authentication purposes. Therefore, we review the relevant literature, conduct several EEG measurement experiments and discuss their procedure and results with experts in the EEG and digital signal processing (DSP) fields.
After gaining enough knowledge on the feature extraction and classification techniques and proposing the most applicable ones for our problem, we build and present a mobile prototype system capable of authenticating users based on the uniqueness of their brain-waves. Furthermore, we implement a novel authentication process, which leads the authentication system to be more secure. We also assess the usability of the system and define possible usage scenarios and propose a number of practical suggestions for future improvements of the system.

Personalized Medicine based on patient journals and family medical history records
The aim of this work was to develop a procedure for analysing and processing large amount of medical data in order to help physicians to make better decisions during the diagnosis process and to forecast high risk patients for developing a specific disease.
The suggested solution is a procedure that combined different techniques that were applied to pre-process, analyse and visualize patient medical record data in order to foresee the patient high risk of developing a specific disease. This is achieved through the analysis of inter, intra-family relationships among patients and their similarities in terms of diagnosed diseases. The above procedure led to the development of a system prototype that will help the physician to make better decisions during the diagnosis process.
The methods followed during the research process in order to reach to the proposed solution consists of primary research, such as an interview with the physician and secondary research such as related work, journal articles, papers, internet sources.
The collaborative filtering technique was used to explore, not only the patients’ intra-family relation, but also, the inter-family relations, in order to define a similarity score among patients. The patients are grouped based on their similarity score.
The Latent Semantic Index clustering technique was used to analyse the group of similar patients in order to foresee the risk of developing a specific disease.
Cluster visualization was used to visualize the results. In this way, the physician can further investigate and understand the results i.e. why a patient has a high risk of developing a specific disease.

Personalized Interactive EPG based on HbbTV
EPG was envisioned as a vital service in digital TV. However the EPG in its current form has not been a success. People continue zapping to select and change programs. The prototype developed during this master thesis uses web-services and recommender techniques to increase the personal benefit of watching television. The main focus is on a personalized interactive electronic program guide with an appealing user interface. To achieve this, state-of-the-art for recommender and profiling systems are studied and user-centric design principles are used to formulate the requirements.

Assessment and Normative Guidance of the Collective Mindset Maturity Regarding Open Data in Smart Cities
A Grounded Theory Approach to the Understanding of Open Data as an Enabler of Strategic Cross-Sector Open Innovation and Long-Term Smart City Sustainability
This master thesis is concerned with the emerging concept of open data and how it functions as an enabler of sustainable smart city solutions. We borrow the concept of maturity from the field of Enterprise Architecture (EA) to describe the level of willingness among smart city actors to open up data and the level of their open data understanding. We want to find out how to create a conceptual model for assessing open data mindset maturity of a smart city ecosystem, which normatively can function as a guideline for relevant actors. A grounded theory methodology is used to incrementally construct knowledge and end up with verified theory.
Empirical data is gathered from interviews with experts in the fields of smart cities, open data, and sustainability and it is analysed by means of systems theory, ecosystems theory, institutional design theory, and open innovation theory.
The findings from the analysis are assembled into a normative model, which we call the Open Governance Maturity Matrix. The maturity matrix aligns the open data willingness and mindsets of relevant actors in a specific open data project and provides guidelines to further action towards successful long-term project realization. It com-bines (1) three important subjects of open data in a smart city context with (2) specific questions for relevant actors and (3) the identification of maturity stages into three dimensions. We show that it is possible to systematically create a model that prescribes or relates to the norm for how to behave in an open data smart city context, and we outline it in an initial, conceptual form. This is an important finding that contributes to contemporary smart city and open data research.
The research yields grounded theory concerning the categorization of open data maturity and suggests a taxonomy outlining five different aspects of maturity in an open data, smart city context. This is a useful tool for understanding and discussing open data among actors. The research concludes that (Theorem 1) sustainability and sustainable development must be fostered from a bottom-up approach in a complex system such as a smart city. Finally we contribute to the smart city discourse by defining a smart city as (Theorem 2) a complex purposive system consisting of ideal-seeking subsystems that are in a continuous process of evolving and integrating with other subsystems and in which actors are in a continuous process of breaking down business silos.
