Lecture Quiz is a game used to provide more active and participant students in lectures. The game is based on a server, a teacher client and a student client. In a master thesis done in 2007, Ole Kristian Mørch-Storstein and Terje Øfsdahl have explored concept of game to be used in higher education and develop a prototype game to further evaluate that concept. Their game has three components; the first one is the server part running on a server. This component connect to a database and provide the services to the others component. The second component is called teacher client, when running the game on a lecture the teacher will use this one to show the game. This one runs on the teacher computer such as a laptop or a PC. The last component is the one running on a mobile phone of students; they will use it to interact with the game. The purpose of the previous game is about illustrating the concept of using game in the lecture. For the game to be used and accepted in the lecture and contribute to the educational environment, a lot of matters need to be considered and improved. In this master thesis, the goal is to extend the Lecture Quiz game with new functionalities that can enhance the management and gameplay of the system. The focus is on the game platform and architecture so that the game can be usable, flexible.

Software development with limited resources is a challenge encountered by most developers at one time or another. The limited resources in question can involve many things like: Time, money, manpower, knowledge etc. Developing countries, due to their general lack of resources are particularly well suited as arenas for the study of this concept The research questions we aim to explore are: 1)How can limited resources affect one’s work organizationally? 2)How can technological decisions affect the resource pool? Our case involves a study of the effects of limited resources on the development process of a person-based family health system in India. Our results indicate that a lack of most specific resources often manifests itself into a more general lack of the resource: Time. Technological decisions can influence time through alteration of the resource pool. Making a technological decision in a limited resource environment should therefore be motivated by the management of time for facilitating the execution of critical tasks.

Increasingly, the ability to improve the efficiency, safety and quality of care is being recognized across the primary health sector. Increased focus on "seamless delivery of care", particularly for those with complex care needs, has highlighted the requirement for improved information exchange between health service providers. Personal Health records (PHR) as a transmission of personal health information can be powerful tools for linking the fragmented information that exists between services and allow providers immediate access to essential clinical information. This research is to make known how personal health records (PHR) can be of a greater support or possible as a backbone for continual of service for primary health care. The acquisition of knowledge by this research is about how personal health records can contribute to the planning of efficient patient’s information which in the long run helps in acquiring the rightful treatment and which also results in the benefit of primary health organization members in the whole. The results illustrate the conceptions of the need to in cooperate and encourage the use of personal health records which in the long effect can serve as a backbone for the existing primary healthcare.

ASTRA is a project that aims at studying awareness systems that help people to feel in touch with family and friends even when they are away from their computers and the existing widespread tools of today (IM, skype, twitter,...) are not enough. In this context, this thesis aims at addressing the problem of Interruption management. The focus will be on the design and development of different interaction mechanisms to support the definition of interruption rules as needed in ASTRA. This will require the extension of the existing Interruption Manager as well as the development of suitable user interfaces, also considering physical interfaces when appropriate. A limited evaluation of the proposed solutions will be evaluated with users.

This project is a continuation of my specialization project which was focused on studying theoretical concepts related to case based reasoning method, rule based reasoning method and integration of them. The integration of rule-based and case-based reasoning methods has shown a substantial improvement with regards to performance over the individual methods. Verdande Technology As wants to try integrating the rule based reasoning method with an existing case based system. This project focuses on designing, implementing and testing of a demo system that demonstrates the development of a rule based reasoning component and integrating it with the existing case based system of Verdande Technology As.

In our everyday tasks context plays an important role, we act based on the information we have or based on what we can see, hear or feel about surrounding. Using this information about context we use to adapt ourselves and our behavior for example in class room we usually whisper when we want to communicate with other class fellow, but in cafeteria we talk normally. Due to the advancements in technology and mobile computing, we are now able to carry computers and smart phones with us, almost everywhere and use them as an alternative to desktop computers. Ubiquitous computing goes step further and refers to the world where computation is being weaved into every day object. In typical ubiquitous computing scenario many invisible computers interact with each other to help user in getting his task done. The ability of being carried easily, i.e. mobility and their presence almost everywhere make it necessary for computer systems, taking part in ubiquitous computing environment, context-aware. If computers can sense the environment they are being used in, they can help user in providing only relevant information, information at correct place and time and such systems can also adapt their behavior according to their surroundings. For example, if would be nice if our mobile phone automatically set to silent profile, whenever we are in class room or in a meeting room. Ubicollab is a platform for supporting collaboration and is a result of research work done in the areas of mobility and ubiquitous computing. Mobility and ubiquity being the inherent properties of UbiCollab, requires it to be aware of context just like another ubiquitous system. It will help UbiCollab applications to adapt their behavior as per surrounding and will enhance the experience of collaboration by using the resources nearby. I researched in the area of context-aware ubiquitous computing and used the results of my research to design and implement a solution for making UbiCollab context-aware. The proposed solution answers research problem related with context itself and different aspect of context. Context definition for UbiCollab has already been defined in work previously done; my solution addresses how to represent this contextual information in simple and effective manner, how to gather location information using different and heterogeneous sensors in understandable and standard format. The outcome of this work comprises of proposed context model, design and implementation of Space Manager for working with spaces, design and usage of flexible data store for storing space information and design and implementation of Location Service Manager for gathering location information using different location sensing technologies.

This project is a continuation of research work done by (Asif, 2009) which proposed an extended architecture of Mobile Student Information System (MSIS) to integrate the systems available for the students to provide student centric services on mobile devices. The architecture was developed by using Service Oriented Architecture (SOA) to provide services for collaboration and communication among the students or between students and the teachers. The mobile services are built by integrating MSIS to Twitter, Feed based systems and NTNU email system. The services have the potential to provide students an experience of a virtual environment of class, project work and discussion groups anytime-anywhere. The project has been carried out in accordance with design-science research model over a number of implementation and evaluation iterations. A user-driven evaluation of the MSIS service has been conducted among a diverse group of NTNU students. The utility as well as the usability of the system were evaluated by applying observational and empirical evaluation methods in a real-world environment at the university. The usability test identified few issues with the initial design of services, and received feedback for enhancements. The Mobile Service Acceptance Model (MSAM) has been used to examine the factors that are influential for user adoption of mobile services in the light of this project. The MSAM instrument measures different facets of a mobile information service, such as the perceived usefulness, ease of use, and usage intention. Our findings confirm that the utility of the student centric mobile services are perceived as high, and students would likely benefit from such kind of services. There is no doubt about the great potential for a service like MSIS and it is believed to be a useful addition to the existing systems.

Clustering is currently more and more applied on hyperlinked documents, especially for web search results. Although most commercial web search engines will provide their ranking algorithms sorting the matched results to raise the most relevant pages to the top, the size of results is still so huge that most ones including some pages that suffers are really interested in will be discarded. Clustering for web search results separates unrelated pages and clusters the similar pages with the same topic into the same group, thus helps suffers to locate the pages much faster. Many features of web pages have been studied to be used in clustering, such as content information including title, snippet, anchor text and etc. Hyperlink is another primary feature of web pages, some content-link coupled clustering methods have been studied. We propose an authoritative K-Means clustering method that combines content, in-link, out-link and page rank. In this project, we adjust the construction of in-link and out-link vectors and introduce a new page rank vector with two patterns, one is a single value representation of page rank and the other is a 11-dimensional vector. We study the difference of these two types of page rank in clustering, and compare the different clustering based on different web page representations, such as content-based, content-link coupled and etc. The effect of different elements of web page is also studied in our project. We apply the authoritative clustering for the web search results retrieved from Google search engine. Three experiments are conducted and different evaluation metrics are adopted to analyze the results.

This project work is about mobile learning system that will enable people to learn and collaborate anywhere and at anytime. It is the continuation of the work carried out in autumn 2009, by Noble and Izaz.In this project work, a Mobile Collaborative Learning System (MCLS) prototype was designed and implemented. The project work has been carried out according to the design science research methodology. An evaluation of the usability of the prototype was conducted. Mobile Services Acceptance Model (MSAM) was used to analyze factors that are influential for user adoption of the prototype.The results from the evaluation indicated that the majority of the test users perceived the prototype to be useful and they intend to use the prototype if they have access to it. These results confirm how useful and beneficial the prototype would be to students.

Nowadays, one subfield of information extraction, Named Entity Recognition, becomes more and more important. It helps machine to recognize proper nouns (entities) in text and associating them with the appropriate types. Common types in NER systems are location, person name, date, address, etc. There are several NER systems in the world. What‘s the main core technology of these systems? Which kind of system is better? How to improve this technology in the future? This master thesis will show the basic and detail knowledge about NER.Three existing NER systems will be choose to evaluate in this paper, GATE, CRFClassifier and LbjNerTagger. These systems are based different NER technology. They can stand for the most of NER existing systems in the world now. This paper will present and evaluate these three systems and try to find the advantage and disadvantage of each system.
