    Treasure the Moment: Communication as a Scaffold for Mobile Learning Activities2016Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    Communication is a fundamental social component of human life and constitutes an indispensable factor in the learning process as it allows the transfer of information between people. Communication supports the interactions that take place in different learning stages and settings and can encourage involvement and cooperation. The "Treasure-HIT" platform, a dedicated environment for designing pedagogical mobile location-based games, encourages social interaction and collaborative learning. This platform, which is social at its base, has limited communication capabilities. Adding such capabilities can overcome this difficulty by providing a more supportive and interpersonal interaction among the involved stakeholders. This thesis explores the users' communication needs for the preparation and enactment of "Treasure-HIT" activities. A design based research was used to analyze the needs in terms of design and technological specifications and develop and implement communication features. Three such features were developed in the course of this thesis: (1) Activities based map, (2) Social media sharing feature (Facebook tasks) and (3) Image gallery. All of those aimed at supporting communication between learners, instructors and their community, before, during and after the activities. Findings show that the developed capabilities enabled new means of communication and contributed to the user experience and learning process. Users appreciated the functionality and ease of use and positively adopted the new features.

    Serviceklass för Facebook Graph API2011Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report is based on a subset of a project that was made for the company SocialWorks. The project included working with web services.

    Through web services, web applications are able to communicate and send data to each other. When a web service is used, the user has to study the web service API. This report addresses a number of problems that might arise from the use of such web services and how these problems can be solved by creating a service class that is used as a middle layer. All API calls will be made through the service class and thus changes in the API will only require modification of code in the service class.

    As a result of this report a service class was created using the PHP framework Zend Framework to facilitate the use of Facebook's Graph API. By using the service class, the user does not have to study the Facebook Graph API in detail. A test application was created to test the service class functionality and manage test users provided by the Facebook Graph API.

    About the Necessity to Change the Perspective for Mobile Web Services2013In: Proceedings of the 15th IEEE International Symposium on Web Systems Evolution (WSE), 2013, IEEE Press, 2013, p. 25-29Conference paper (Refereed)
    Abstract [en]

    The use of Web Services in modern software development is widely accepted and provides (integrated in an according architecture) a fast, flexible and scalable way for the implementation of modern software products. On the other hand, the development of mobile applications, so called apps, becomes more and more important. While using Web Services also from mobile devices is an already accepted scheme in the development of mobile apps, there is not much work done yet for providing Web Services on mobile devices. Therefore, this paper presents a new perspective to Web Services that could be run on mobile devices and, by this, become mobile Web Services.

    Using Cloud Services to Develop Learning Scenarios from a Software Engineering Perspective2013In: Journal of universal computer science (Online), ISSN 0948-695X, E-ISSN 0948-6968, Vol. 19, no 14, p. 2017-2053Article in journal (Refereed)
    Abstract [en]

    The term "Cloud Computing" does not primarily specify new types of core technologies but rather addresses features to do with integration, inter-operability and accessibility. Although not new, virtualization and automation are core features that characterize Cloud Computing. In this paper, we intend to explore the possibility of integrating cloud services with educational scenarios without re-defining neither the technology nor the usage scenarios from scratch. Our suggestion is based on certain solutions that have already been implemented and tested for specific cases.

    About the Development of Scenarios for Mobile Web Service Provisioning2013In: 2013 World Congress on Computer and Information Technology (WCCIT),, IEEE Press, 2013, p. 1-6Conference paper (Refereed)
    Abstract [en]

    Web Services are today a well-accepted technology. Especially in the area of Cloud Computing, Web Services usually provide one of the building blocks of the used technology. Another driving technology nowadays are mobile devices. Nevertheless, there is not much research conducted yet in bringing these two important technologies together, e.g. with respect to providing Web Services on mobile devices. While there is already some technology that allows to deploy Web Services directly on mobile devices, it seems that there is still a lack of research about use-cases and/or scenarios that benefit from mobile Web Services. Therefore, this paper presents an approach that allows the evaluation of both, the technology for providing Web Service on mobile devices and mobile Web Services themselves.

    Implementation of Asynchronous Mobile Web Services: Implementation and First Usage2014In: Proceedings of the 4th International Conference on Cloud Computing and Services Science, 2014, SciTePress, 2014Conference paper (Refereed)
    Abstract [en]

    Mobile devices are nowadays used almost ubiquitously by a large number of users. 2013 was the first year in which the number of sold mobile devices (tablet computers and mobile phones) outperformed the number of PCs' sold. And this trend seems to be continuing in the coming years. Additionally, the scenarios in which these kinds of devices are used, grow almost day by day. Another trend in modern landscapes is the idea of Cloud Computing, that basically allows for a very flexible provision of computational services to customers. Yet, these two trends are not well connected. Of course there exists already quite a large amount of mobile applications (apps) that utilize Cloud Computing based services. The other way round, that mobile devices provide one of the building blocks for the provision of Cloud Computing based services is not well established yet. Therefore, this paper concentrates on an extension of a technology that allows to provide standardized Web Services, as one of the building blocks for Cloud Computing, on mobile devices. The extension hereby consists of a new approach that now also allows to provide asynchronous Web Services on mobile devices, in contrast to synchronous ones. Additionally, this paper also illustrates how the described technology was already used in an app provided by a business partner.

    Provision of Personalized Data via Mobile Web Services in eHealth Scenarios2014In: Proceedings of the 10th International Conference on Web Information Systems and Technology: Volume 1 / [ed] Valérie Monfort, Karl-Heinz Krempels, SciTePress, 2014, Vol. 1, p. 441-446Conference paper (Refereed)
    Abstract [en]

    In societies where the demographic change leads to a more and more unbalanced state between the elderly and all other different age groups, there, health management becomes one of the most significant problems, e.g., in order to allow what is often called successful aging. Ubiquitous use of smart mobile devices enables gathering of personalized data enriched with contextual information. This information can ideally be used in modern eHealth scenarios, resulting in mobile health (mHealth) scenarios. This paper describes how highly personalized and sensitive information, such as vital signs enriched with contextual information of a patient, can be stored at mobile devices and provided via modern web technologies for later-on analysis and health monitoring. Therefore, this paper presents a number of different scenarios in which such mobile technology provides certain benefits, discusses benefits, drawbacks and challenges of such an approach and describes an example implementation of an mHealth scenario.

    Object detection and single-board computers: En förstudie gjord på Saab AB2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Saab is currently using an old and complex system to perform tests of their products. The system is based on filming from different angles which will be merged to one film from which Saab can analyze the results of their products. Single-board computers is something that have become increasingly popular in the recent years, therefore, we are to investigate whether it is possible or not to replace the older systems with SBCs and cameras.We will also investigate whether the BeagleBoard is capable of detecting objects while filming, synchronizing, encoding and saving the video for later use.The result showed that the processor isn’t powerful enough to handle object identification without full hardware support. Instead, it needs to be performed afterwards by a computer which will identify objects in the video. A better method has been proposed to make object identification smarter and learning, which will work better in Saab’s case and their future work.

    Measurement and comparison of clustering algorithms2007Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this project, a number of different clustering algorithms are described and their workings explained. They are compared to each other by implementing them on number of graphs with a known architecture.

    These clustering algorithm, in the order they are implemented, are as follows: Nearest neighbour hillclimbing, Nearest neighbour big step hillclimbing, Best neighbour hillclimbing, Best neighbour big step hillclimbing, Gem 3D, K-means simple, K-means Gem 3D, One cluster and One cluster per node.

    The graphs are Unconnected, Directed KX, Directed Cycle KX and Directed Cycle.

    The results of these clusterings are compared with each other according to three criteria: Time, Quality and Extremity of nodes distribution. This enables us to find out which algorithm is most suitable for which graph. These artificial graphs are then compared with the reference architecture graph to reach the conclusions.

    The Effect of Emotions and Social Behavior on Performance in a Collaborative Serious Game Between Humans and Autonomous Robots2018In: International Journal of Social Robotics, ISSN 1875-4791, E-ISSN 1875-4805, Vol. 10, no 1, p. 115-129Article in journal (Refereed)
    Abstract [en]

    The aim of this paper is to investigate performance in a collaborative human–robot interaction on a shared serious game task. Furthermore, the effect of elicited emotions and perceived social behavior categories on players’ performance will be investigated. The participants collaboratively played a turn-taking version of the Tower of Hanoi serious game, together with the human and robot collaborators. The elicited emotions were analyzed in regards to the arousal and valence variables, computed from the Geneva Emotion Wheel questionnaire. Moreover, the perceived social behavior categories were obtained from analyzing and grouping replies to the Interactive Experiences and Trust and Respect questionnaires. It was found that the results did not show a statistically significant difference in participants’ performance between the human or robot collaborators. Moreover, all of the collaborators elicited similar emotions, where the human collaborator was perceived as more credible and socially present than the robot one. It is suggested that using robot collaborators might be as efficient as using human ones, in the context of serious game collaborative tasks.

    Mobile development: Linnaeus University App for Exchange students2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Every year approximately a thousand of exchange students arrive to Växjö looking forimproving their university experience. The main problem is that this amount of peopleis very difficult to handle and organize. Sometimes, students don’t have enoughsupport, missing important information, missing interesting events and so on.

    In consequence, the students can develop a bad feeling about the universityorganization giving a bad feedback to the future potential incoming students. This is abad aspect to Linnaeus University because it is losing future students.

    In order to solve the problem, different surveys have been done to the internationalstudents, and even to the Växjö International Students (VIS) organization.

    The findings from these surveys are very interesting, and it is possible to identify andgroup different problems in order to make the solution easier.

    Furthermore, a good solution is found, improving the situation we were before. The solution found will fit in the hand of each student and will bring us in a better situationfor the university and their students.

    Tabulex, en algoritmutbrytning: Analys och jämförelse mellan objektorienterade språk2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Tabulex is a software produced and developed by IST AB that manages scheduling for schools. The purpose of this project was to extract an algorithm embedded in the software written inDelphi and translate it into Java. These languages share many similarities due to them bothbeing object oriented. Studies were made to compare the differences in the languages on themost basic of concepts such as: performance, inheritance, classes and encapsulation. To achievea more thorough basis for this study other programming languages in the object orientatedparadigm were compared as well. Tests were made between C++, C# and Java to test andanalyse differences in execution time on a few selected algorithms. The report also refers toexternal tests where the languages are tested using the same principle as above. With theextraction of the algorithm the biggest difference was how Delphi handles encapsulation incomparison to Java. The extraction of the algorithm succeeded and you could see clearimprovements in execution time and efficiency. The performance comparisons showed adifference in execution-time in the different programming languages. C++ was the fastest andit could be linked to the fact that C++ has pointers which allows a programmer to refer directlyto a specific location in memory. Some of the time-differences could also be linked to differentcompilers and support for features such as JIT - Just in time compilation.

    Generellt interface till Javadoc2005Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this work was to examine the possibility to get a well functioning interface between ©VizzAnalyzer [3] and Javadoc, thereby be able to produce html documentation of the analysed classes. The VizzAnalyzer analyses java programs and so produces an abstract syntax tree (AST) that represents the analysed program. This AST can then be coupled to the internal AST model of javadoc to represent the classes that were part of the analysis. The result of this is a complete documentation of the analysed classes. There is also the possibility to add further information about them that may have been discovered during analysis. A more general interface was also made in addition to the interface for VizzAnalyzer. This interface can be coupled with any program that can produce a suitable representation of the analysed program. This is mostly pertinent to java code, but due to classes being represented only as text before they are processed by the interface, there is a possibility to use it for other object oriented languages.

    Sökmotoroptimering för video: Tekniker och skillnader2012Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study wishes to show whether the selected search engine optimization affects a webpage's SERP position on pages with video. The study includes video sitemap and schema.orgs markup for video.

    An empirical study has been carried out on three test domains where various search engine optimization techniques were implemented on the webpages. A site search engine optimized for video, a site search engine optimized for text content and a site search engine optimized with both techniques. Videos were frequently uploaded to the webpages and the sites SERP positions in Google search engine were noted on a predetermined search term.

    The results show that schema.orgs markup for video and video sitemap has some positive effect on search engine optimization.

    Presentation av pedagogiska texter på webben2008Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien var att fastställa hur man presenterar en pedagogisk text på webben så att den blir tillgänglig, läsbar och användbar för målgruppen. Undersökningen gjordes med en inledande

    forskningsöversikt och därpå följande litteraturstudier. Speciellt värdefull visade sig WCAG 2.0 (Web Content Accessibility Guidelines) vara som dessutom ligger till grund för såväl litteratur inom området som för framtagna riktlinjer för svenska myndigheter. Metoder för att mäta graden av tillgänglighet, läsbarhet och användbarhet utvärderas i teoridelen, bland vilka Lix kan nämnas. Därefter skapades en enkel webbsida i enighet med de riktlinjer som

    tagits fram med enkäter, intervjuer och litteraturstudier. Denna webbsida utvärderas med enkäter, intervjuer och tidigare framtagna mätmetoder. Resultatet av studien mynnar ut i en kravlista med punkter som en pedagogisk text för webben bör uppfylla. Denna lista delas in i fyra delar: strävansmål, mål för tillgänglighet, mål för läsbarhet samt mål för användbarhet. Exempel på punkter från kravlistan är: Texten ska vara enkel och lättläst,

    erbjud uppläsning av texten, radavståndet ska vara minst 150% samt information om när dokumentet skapades/ändrades och av vem ska finnas med på webbsidan.

    [demos.v1.0] till [demos.v2.0]: En fallstudie av modifierbarhet2005Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report is an examination paper in computer science at University of Växjö. The report will focus on the possibility to create adaptable systems and to cost calculate the work needed to modify a system to meet new demands. A project [demos] developed by Interactive Institute studio [12-21] in Växjö is the starting point in our work. They have during a period of two years developed a prototype of a system which intends to get youth and democratic selected representatives a communication platform where they may communicate with SMS. Today they are in a position when they want to develop the system for other user groups with slighter different purpose and to do that they need a more flexible system. In a problem analysis they found out three mayor drawbacks in the system that needed to be changed; member system, the interface to the mobile operator and the managing of messages. These scenarios were analysed with a method called ALMA and in this analyse we found out that the system as it is now is hard to modify. After redesigned and modified the system from [demos.v1] to [demos.v2] we analysed the system again with the ALMA-method and besides the three initial scenarios we also added three new forthcoming scenarios to see how the developed version will meet this demands. The result of this test showed that [demos.v2] was better developed to stand new changes at lower costs than the original system.

    Internet of things security in healthcare: A test-suite and standard review2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Internet of things is getting more and more popular in healthcare as it comes with benefits that help with efficiency in saving lives and reduce its cost, but it also presents a new attack vector for an attacker to steal or manipulate information sent between them. This report will focus on three properties in the definition of security, confidentiality, integrity and access control. The report will look into what challenges there is in healthcare IoT today through a literature review and from those challenges look into what could minimise these challenges before a device gets into production. The report found that the lack of standardisation has lead to errors that could be easily prevented by following a guideline of tests as those from the European Union Agency for Network and Information Security, or by running a penetration test with the tools brought up in the report on the device to see what vulnerabilities are present.

    Utveckling av ett öppet Home Automation-protokoll för användning över IP-nätverk2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report covers the development of a new protocol for use in Home Automation over IP networks, with focus on flexibility and simplicity. We chose to develop a new protocol for Home Automation because a review of current protocols suggests that these aren't open or flexible enough to suit every device in use or every scenario that might be applicable.

    In our literature studies we gathered information for use as the basis of our protocol and give us more insight into the technologies behind current home automation protocols. This also gave us the opportunity to compare our finished protocol with existing protocols. The method we chose for developing the protocol is a generic design method where after reviewing existing protocols, we establish a number of goals for the new protocol. It did however turn out to be difficult to acquire relevant information about some of the protocols. Because of this we used a slightly different approach, basing the new protocol on a number of scenarios we want it to be able to handle.

    The result is a protocol which satisfied almost every goal we established. For the few it didn't, we made it possible to satisfy them with future expansions.

    Remote Tower Center - Planning Tool2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Saab has a product, Remote Tower, which allows air traffic controllers to supervise and control an airport remotely. Today an air traffic controller can operate on one airport at the time and switch between airports. The next phase of this system is to allow the air traffic controller to simultaneously control multiple airports, i.e. going from controlling airports in sequence to controlling airports in parallel. The airports are connected to and controlled from one single airport control center. This leads to a planning problem, both in long term and short term, for staffing this airport control center to maintain the capacity of the connected airports. This thesis will present the process of the development of a tool allowing a user to plan the schedule the staffing of a remote tower center. By utilizing this tool the impact of different restrictions affecting the planning will be evaluated and presented in the results.

    Distribution and configuration of agents for NMS in a reasonable time2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    With this paper we intended to simplify deployment and management of monitoring agents for a Network Monitoring System. We found interest on the subject since the time consumed to deploy and manage agents was found to be very inefficient. During a lecture with the Swedish based company Op5 AB at the Linnaeus University in Kalmar, Sweden, we presented the complex of problem. The lecturer showed great interest in a solution on the subject and we found it to be a great thesis subject for the Bachelor degree in Computer Science.

    By the year of 2016 it is expected that the number of network connected devices will grow threefold, there will be four times as much IP traffic and the data storage demand will increase tenfold. [8] This growing demand will also affect the requirement on the Network Monitoring System and in turn the monitoring agents.

    In this paper we created a baseline, which consisted of a timing regarding the time consumption for manual deployment, configuration and management of the monitoring agents. We also developed an automated way for deployment, configuration and management of monitoring agents by integrating a Content Management Software called Puppet, combined with several scripts. To simplify the management and deployment furthermore a widget was developed for Op5’s Web based User Interface called Ninja.

    The developed solution was measured against the baseline and a result regarding time consumption was presented. The result fell into a discussion on the subject of automatization and the time savings that it may result in due to less frequent human errors and a less repetitive work processes.

    Mobila enheter: Anpassning av hemsidor skapade med EPIServer CMS2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    ”Mobila enheter – anpassning av hemsidor skapade med EPiServer CMS” handlar om tekniker och metoder för att anpassa en hemsida skapad i publiceringsverktyget EPiServer CMS för mobila enheter. Rapporten berör både tekniska bitar så som hur man kan presentera två helt olika versioner av samma sida och hur man löser scrollning på mobila enheter till mer teoretiska avsnitt som handlar om hur man presenterar innehåll som passar den mobila enhetens skärm.Syftet var att undersöka om det är möjligt att skapa återanvändbar kod som går att använda på flera olika webbplatser och samtidigt skapa den mobila versionen med samma html-kod som redan finns och på så sätt undvika extra arbete för att koda om sidorna. Vidare så undersöktes det om det gick att få en ”app-känsla” på den mobila versionen utan att utveckla en nativ applikation.

    Multivariate Networks: Visualization and Interaction Techniques2013Doctoral thesis, monograph (Other academic)
    Abstract [en]

    As more and more data is created each day, researchers from different science domains are trying to make sense of it. A lot of this data, for example our connections to friends on different social networking websites, can be modeled as graphs, where the nodes are actors and the edges are relationships between them. Researchers analyze this data to find new forms of communication, to explore different social groups or subgroups, to detect illegal activities or to seek for different communication patterns that could help companies in their marketing campaigns. Another example are huge networks in system biology. Their visualization is crucial for the understanding of living beings. The topological structure of a network on its own could give insight into the existence or distribution of interesting actors in the network. However, this is often not enough to understand complex network systems in real-world applications. The reason for this is that all the network elements (nodes or edges) are not simple one-dimensional data. For instance in biology, experiments can be performed on biological networks. These experiments and network analysis approaches produce additional data that are often important to be analyzed with respect to the underlying network structure. Therefore, it is crucial to visualize the additional attributes of the network while preserving the network structure as much as possible. The problem is not trivial as these so-called multivariate networks could have a high number of attributes that are related to their nodes, edges, different groups, or clusters of nodes and/or edges.

    The aim of this thesis is to contribute to the development of different visualization and interaction techniques for the visual analysis of multivariate networks. Two research goals are defined in this thesis: first, a deeper understanding of existing approaches for visualizing multivariate networks should be acquired in order to classify them into categories and to identify disadvantages or unsolved visualization challenges. The second goal is to develop visualization and interaction techniques that will overcome various issues of these approaches.

    Initially, a brief survey on techniques to visualize multivariate networks is presented in this thesis. Afterwards, a small task-based user study investigating the usefulness of two main approaches for multivariate network visualization is discussed. Then, various visualization and interaction techniques for multivariate network visualization are presented. Three different software tools were implemented to demonstrate our research efforts. All features of our systems are highlighted, including a description of visualization and interaction techniques as well as disadvantages and scalability issues if present.

    The Network Lens: Interactive Exploration of Multivariate Networks Using Visual Filtering2010In: Proceedings of the 14th International Conference on Information Visualisation (IV '10), IEEE, 2010, p. 35-42Conference paper (Refereed)
    Abstract [en]

    Networks are widely used in modeling relational data often comprised of thousands of nodes and edges. This kind of data alone implies a challenge for its visualization as it is hard to avoid clutter of network elements if using traditional node-link diagrams. Moreover, real-life network data sets usually represent objects with a large number of additional attributes that need to be visualized, such as in software engineering, social network analysis, or biochemistry. In this paper, we present a novel approach, called Network Lens, to visualize such attributes in context of the underlying network. Our implementation of the Network Lens is an interactive tool that extends the idea of so-called magic lenses in such a way that users can interactively build and combine various lenses by specifying different attributes and selecting suitable visual representations.

    Content Visualization of GeoAudio Notes2008Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The total population of GPS-enabled location-based services (LBS) subscribers is constantly increasing. This fact implies new research possibilities for visualizing geospatial data produced by these mobile devices. The aim of this thesis is to explore novel techniques and methods to visualize the content of voice notes (messages recorded by users on GPS-enabled devices) that will be placed in maps using GPS coordinates, and visualize the semantical, temporal, and spatial relations between the notes. Our research is part of the Geovisualization field which deals with geospatial data.

    Based on our research and analyzes of this problem, we combined different visualization and interaction techniques, thus providing a novel approach to achieve the research aim. We have built a prototype application, called GNV System (GeoAudio Notes Visualization System), that demonstrates our achievements.

    Network Visualization for Digital Humanities: Two Case Studies of Visual Analyses for Text Analytics2016In: International Symposium on Digital Humanities, Växjö 7-8 November 2016: Book of Abstracts, Linnaeus University , 2016, p. 39-43Conference paper (Refereed)
    Abstract [en]

    Much of the data created nowadays in fields such as Digital Humanities (DH) is of relational nature, such as social or semantic networks. Researchers often decide to depict networks as node-link diagrams to make a better sense of the complex nature of data. Understanding the topology of such a network can be very important. For instance, if we show our friends as network nodes and their friendship as edges between the nodes, it becomes easy to identify groups of friends from different social settings (work friends, high school friends, etc.).

    Networks usually have additional attributes attached to their elements. For instance, we can model a number of documents in a repository as nodes and use edges to describe co-authorship. Additionally, we might want to explore other aspects of such a corpus, like the keywords for each document, its genre, and various other data associated. Here, it is often desirable to get an overview about the network structure and how different data values relate to this structure. In this paper, we present two case studies for visualizations in DH with a focus on publication networks. But first, we will introduce our data sets used in these studies.

Kao, Ming C. Hao, Chaomei Chen, Robert Kosara, Mark A. Livingston, Jinah Park, and Ian Roberts, SPIE - International Society for Optical Engineering, 2012Conference paper (Refereed)
    Abstract [en]

    Ontologies and hierarchical clustering are both important tools in biology and medicine to study high-throughput data such as transcriptomics and metabolomics data. Enrichment of ontology terms in the data is used to identify statistically overrepresented ontology terms, giving insight into relevant biological processes or functional modules. Hierarchical clustering is a standard method to analyze and visualize data to find relatively homogeneous clusters of experimental data points. Both methods support the analysis of the same data set, but are usually considered independently. However, often a combined view is desired: visualizing a large data set in the context of an ontology under consideration of a clustering of the data. This paper proposes a new visualization method for this task.

    Visual Exploration of Relationships between Document Clusters2014In: IVAPP 2014: Proceedings od the 5th International Conference on Information Visualization Theory and Applications / [ed] Robert S. Laramee, Andreas Kerren, José Braz, SciTePress, 2014, p. 195-203Conference paper (Refereed)
    Abstract [en]

    The visualization of networks with additional attributes attached to the network elements is one of the ongoing challenges in the information visualization domain. Such so-called multivariate networks regularly appear in various application fields, for instance, in data sets which describe friendship networks or co-authorship networks. Here, we focus on networks that are based on text documents, i.e., the network nodes represent documents and the edges show relationships between them. Those relationships can be derived from common topics or common co-authors. Attached attributes may be specific keywords (topics), keyword frequencies, etc. The analysis of such multivariate networks is challenging, because a deeper understanding of the data provided depends on effective visualization and interaction techniques that are able to bring all types of information together. In addition, automatic analysis methods should be used to support the analysis process of potentially large amounts of data. In this paper, we present a visualization approach that tackles those analysis problems. Our implementation provides a combination of new techniques that shows intra-cluster and inter-cluster relations while giving insight into the content of the cluster attributes. Hence, it facilitates the interactive exploration of the networks under consideration by showing the relationships between node clusters in context of network topology and multivariate attributes.

    A New Radial Space-Filling Visualization Approach for Planar st-Graphs2012In: Poster Abstracts of IEEE VisWeek 2012, 2012Conference paper (Refereed)
    Abstract [en]

    Planar st-graphs are used in a number of different application fieldsin the sciences, but also in industry. So far, mainly node-link-basedlayouts have been used to visualize such graphs especially in theGraph Drawing community. One drawback of these standard layoutsis their high consumption of space. In Information Visualization,there exist visualization techniques for graphs which achieveconsiderable space savings, such as matrix-based approaches. Inthis work, we present a novel space-filling representation to visualizeplanar st-graphs.

    Abstract [en]

    The amount of data produced in the world every day implies a huge challenge in understanding and extracting knowledge from it. Much of this data is of relational nature, such as social networks, metabolic pathways, or links between software components. Traditionally, those networks are represented as node-link diagrams or matrix representations. They help us to understand the structure (topology) of the relational data. However in many real world data sets, additional (often multidimensional) attributes are attached to the network elements. One challenge is to show these attributes in context of the underlying network topology in order to support the user in further analyses. In this paper, we present a novel approach that extends traditional force-based graph layouts to create an attribute-driven layout. In addition, our prototype implementation supports interactive exploration by introducing clustering and multidimensional scaling into the analysis process.

    Abstract [en]

    Approaches to investigate biological processes have been of strong interest in the past few years and are thefocus of several research areas, especially Systems Biology. Biochemical networks as representations ofprocesses are very important for a comprehensive understanding of living beings. Drawings of these networksare often visually overloaded and do not scale. A common solution to deal with this complexity is to divide thecomplete network, for example, the metabolism, into a large set of single pathways that are hierarchicallystructured. If those pathways are visualized, this strategy generates additional navigation and explorationproblems as the user loses the context within the complete network.

    In this article, we present a general solution to this problem of visualizing interconnected pathways anddiscuss it in context of biochemical networks. Our new visualization approach supports the analyst in obtainingan overview to related pathways if they are working within a particular pathway of interest. By usingglyphs, brushing, and topological information of the related pathways, our interactive visualization is ableto intuitively guide the exploration and navigation process, and thus the analysis processes too. To deal withreal data and current networks, our tool has been implemented as a plugin for the VANTED system.

    TapVis: A Data Visualization Approach for Assessment of Alternating Tapping Performance in Patients with Parkinson's Disease2018In: EuroVis 2018 - Short Papers, 2018, p. 55-59Conference paper (Refereed)
    Abstract [en]

    Advancements in telemedicine have been helpful for frequent monitoring of patients with Parkinson's disease (PD) from remote locations and assessment of their individual symptoms and treatment-related complications. These data can be useful for helping clinicians to interpret symptom states and individually tailor the treatments by visualizing the physiological information collected by sensor-based systems. In this paper we present a visualization metaphor that represents symptom information of PD patients during tapping tests performed with a smartphone. The metaphor has been developed and evaluated with a clinician. It enabled the clinician to observe fine motor impairments and identify motor fluctuations regarding several movement aspects of patients that perform the tests from their homes.

    Nowadays blogs are regarded as tools for communication as well as an important source for spreading information in almost every subject. In recent years, school teachers have started to take advantage of this technology in order to support their educational practices. In this paper we focus on the data generated by a project involving more than 50 Swedish schools where teachers and pupils are posting content related to their astronomy class activities in their blogs with the aims of improving the teaching process. The challenge here is to find suitable methods to explore all these blogs in an interactive and discovery fashion. Our proposed solution to this challenge is to provide a visual and interactive tool for the exploration of blog corpora by teachers, pupils, project managers and parents.

    Design Patterns for Multi-Agent Systems2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Design patterns document a field's systematic knowledge derived from experiences. Despite the vast body of work in the field of multi-agent systems (MAS), design patterns for MAS are not popular among software practitioners. As MAS have features that are widely considered as key to engineering complex distributed applications, for example in manufacturing, robotics, ecommerce, traffic control and coordination, science simulations, it is important to provide a clear overview of existing patterns to make this knowledge accessible. To that end, a systematic literature review was performed covering the main publication venues of the field since 1998, resulting in 206 patterns.

    The study shows that (1) there is a lack of a standard template for documenting design patterns for MAS, which hampers the use of patterns by practitioners, (2) associations between patterns are poorly described, which results in a lack of overview of the pattern space, (3) patterns for MAS have been used for a variety of application domains, which underpins their high potential for practitioners, and (4) classifications of design patterns for MAS are bounded to specific pattern catalogs, a more holistic view on the pattern space is missing. From the study, a number of guidelines is outlined that are important for future work on design patterns for MAS and their adoption in practice.
