Master
Analyzing distributed ledger data structures for the immutable persistence of transactions and tamper-secure execution of processes
Posted on 31. Aug 2018; Supervised by Prof. Dr. Thomas Rose; Advisor(s): Thomas Osterland
Often only noticed as a technology that enables the digital currency Bitcoin, blockchain is a novel protocol that allows the distributed and secure storing of information and untampered execution of program code in trust-less environments. As part of a broader range of technologies that allow the immutable storage of information in decentralized networks, where network participants build a consensus about the correctness of persisted information, the classical blockchain is only one specific implementation of distributed ledger technologies. Other ledger technologies are based on directed acyclic graphs (DAGs). Topic of this thesis is the exploration and implementation of a DAG based ledger in the existing blockchain framework Labchain (https://github.com/putschli/LabChain).

Interactive Support for Business Modelling
Posted on 21. Jun 2017; Supervised by Prof. Dr. Thomas Rose; Advisor(s): Thomas Osterland
A business model is an abstract model of the business of one or more cooperating organisations. It is a conceptual and architectural implementation of a business strategy and the foundation for the implementation of business processes and information systems. The research objective of this thesis is the design, implementation and evaluation of an interactive tool for the engineering of a business model.

Measuring coherence accross media in learning environments
Posted on 28. Sep 2017; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Dr. Marc Spaniol
Multimedia content based indexing delivered a lot of models for the analysis of multimedia materials. In modern educational platforms, e.g. MOOCs and self-regulated learning platforms. In consequence, multimedia materials are produced by educational designers but also by the learners during their learning processes. Coherence is a semantic measure for the local and global connectivity of e.g. sentences, paragraphs, videos, slides among others. Computer linguistics has provided impressive results for measuring the quality of writing, e.g. for automatic essay scoring. To measure the coherence of multimedia materials many computational methods reaching from natural language processing to machine learning needs to be combined in a common coherence model. Goal of this master thesis is to co-develop a coherence model for cross-media coherence and to prototypically combine these computational methods for a webinar.
Master
Mobile Edge Cloud Computing - Offloading strategies
Posted on 14. May 2021; Supervised by PD Dr. Ralf Klamma, AOR
Mobile edge cloud computing provides a platform to accommodate the offloaded traffic workload generated by mobile devices. It can significantly reduce the access delay for mobile application users. However, the high user mobility brings significant challenges to the service provisioning for mobile users, especially for the delay-sensitive mobile applications. We want to research how to update the service provisioning solution for a given community of mobile users. Therefore, we compare current offloading strategies, information structures based on peer-to-peer in combination with cloud computing and client-side solutions using advanced Web protocols like WebRTC.

Process model-oriented creation of smart contracts
Posted on 31. Aug 2018; Supervised by Prof. Dr. Thomas Rose; Advisor(s): Thomas Osterland
Often only noticed as a technology that enables the digital currency Bitcoin, blockchain is a novel protocol that allows the distributed and secure storing of information and untempered execution of program code in trust-less environments. Did you ever feel the intense desire to write a thesis about blockchain or do you have a slight hope that blockchain is the one-and-only topic that touches your heart? Use your chance now! We are looking forward to hear from you.

Simulation tools for the Assessment of Emergency Management Processes
Posted on 12. Sep 2018; Supervised by Prof. Dr. Thomas Rose; Advisor(s): Thomas Osterland
Large scale disasters represent a major challenge for any medical service. Typically such disasters, be they founded in terrorism, natural or technical catastrophize, generate a significant number of casualties (MASCAL – Mass Casualty) with severe and unusual injury patterns. Many processes are supported by Standard Operating Procedures as common practice, but any catastrophe requires a change of processes due to the nature of the disaster and thus furnishes a major challenge for hospital operations. As of now, hospitals and medical services are designed for a specific workload that has been agreed among different stakeholders. Hence, processes and their resources are designed in light of best practices for patient care as well as anticipated workload.
Master
Standard compliant WebXR Rendering of Mixed Reality Learning Experiences
Posted on 03. Jun 2020; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Fridolin Wild (Open University of the UK)
The goal of this master thesis is to build a reference implementation for a player that renders Augmented Reality Learning Experience Models (ARLEM, IEEE standard P1589-2020) using the WebXR device APIs. WebXR is a collection of standards that support rendering of 3D scenes in Augmented Reality on eyeglasses as well as handheld devices. ARLEM is tested on, for example, training sequences for astronauts.

Agent-Object Interactions in Mixed Reality Learning Applications
Supervised by PD Dr. Ralf Klamma, AOR; Advisor(s): Benedikt Hensen, M.Sc.
Mixed reality agents have a large potential for mixed reality learning applications, e.g. by providing a natural user interface to a chatbot or as a tutor who can demonstrate practical actions and guide the user through a complex environment. When creating such a virtual agent, one challenge concerns the scalability of interactions with the environment. The virtual agent must be able to interact with a large variety of different objects that can be both virtual but also real in the case of augmented reality. Hence, a consistent data description language and a decision-making architecture are required, so that the agent can understand the possible interaction affordances in the environment. Previous approaches from game development e.g. include "smart objects" in the Sims franchise which provide such distributed world knowledge.
Bachelor
Detection of malicious social bots in online social networks using AIS
Online social networks (OSNs) have become one of the main types of online applications enabling the exchange of information between a large number of users, which, however, at the same time raises new security and privacy concerns. Unexpectedly for many users, automated accounts, known as social bots, are increasingly contributing to the information distribution process. Artificial immune systems (AIS) use concepts and algorithms inspired by human immune system theory. AIS is able to adapt to the changing nature and behavior patterns of malicious social bots.

Reach for the Stars: Gamified Group Work in Mixed Reality
Miesner, Jakob in 2021; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Dr. Stefan Decker; Advisor(s): Benedikt Hensen, M.Sc.
Collaboration and group work are essential parts of learning since they encourage students to exchange ideas, to learn from each other and to support each other. The ability to work as a team increases the quality and amount of results and is therefore a highly demanded soft skill. However, students who face group work in courses still encounter challenges regarding efficient coordination, motivation and communication when working on group assignments or in learning groups. This becomes evident in processes where one person does all the work. Other common examples include a lack of communication where the group accumulates their individual results only at the end of the project and the participants cannot compensate if some members failed to deliver their results on time. Mixed Reality bears the potential to provide a structured 3D environment for organization and collaboration where group tasks can be split up visually between participants in virtual meetings. Additionally, Gamification can provide means of motivation to continue with a learning task and to strengthen the unity of the team.

Utilize Chat Interfaces for Social Bot Creation
Social Bots (software robots) are computer algorithms that automatically produce content and interact with humans on social media. This thesis will utilize chat interfaces and a social bot framework to create social bots. It will also extend the framework to support various social bot types (e.g. chatbots, crawlers, transactional bots or informational bots).
