Overview

Assignment of theses

The final theses in the AG Riehle are usually not pure literature theses but include the development of small prototypes or the collection and analysis of data. Below you will find a list of suggested topics. It is also possible to submit your own topic suggestions, as long as they can be assigned to one of the following topics:

Sensors and Internet-of-Things (LoRa, etc.)
Cloud architectures (IT infrastructures, virtualization, orchestration, etc.)
Data management and data analytics

Please refrain from inquiries that cannot be assigned to any of the above areas.

Topics for theses

Implementation and Evaluation of an Application for Geolocation of IoT Sensors using LoRa Gateways

For: Master

In this thesis, the geolocation of IoT sensors will be implemented, tested, and evaluated using LoRa gateways on the campus. The existing possibilities for geolocation of the LoRa gateways will be used.

Development of an automated interface for the door locking system at the University of Koblenz

For: Bachelor, Master

The University of Koblenz operates an electronic system for managing door keys, which requires various employee data. Additionally, this information is stored in the university's ERP (Enterprise Resource Planning) system. Currently, the process of transferring data between these two systems is conducted manually via paper-based methods. However, both systems are equipped with data interface capabilities. This project aims to develop middleware that will enable automatic synchronization of data from the ERP system to the key management application, streamlining the process for enhanced efficiency and accuracy.

Development and Evaluation of a Hybrid Chatbot Architecture

For: Bachelor, Master

Traditional chatbots often have limited capabilities in natural language processing, as they rely on predefined rules to understand the user input and respond accurately. In the recent past, Large Language Models (LLMs) have been increasingly integrated into chatbots due to their strengths in processing and generating natural language. The use of LLMs, however, is not without drawbacks, since they tend to produce hallucinations, meaning inaccurate, factually incorrect, and even harmful responses. The goal of this thesis is to implement and evaluate a hybrid chatbot architecture that utilizes both, traditional chatbot techniques and LLMs, to mitigate their respective weaknesses.

Application for a topic

Please proceed as follows when applying for thesis supervision:

Contact the respective tutor responsible for your topic via e-mail.
Briefly explain your motivation for the targeted topic.
In the attachment to your e-mail, send an excerpt of your previous academic achievements so that we can see which subjects you have successfully completed.
Indicate the date when you would like to write the thesis (from/until).

We will be happy to explain the detailed terms of reference to you in a personal meeting afterwards. Please note: A condition for supervision is the acceptance of a research proposal written by you. You will receive the necessary assistance from your chosen tutor.

Templates

Research proposal

For all theses, a research proposal according to our template must be submitted before starting the work. Please send this proposal to your tutor for approval.

Research proposal template for theses

The research proposal is divided into the sections "Motivation of the thesis", "Formulation of objectives" and "Methodological approach". The proposal should already be provided with several literature sources, especially in the area of motivation, and should consist of a total of 1-2 pages of text.

Writing the thesis

The processing time for your thesis can be found in your examination regulations; as a rule, this is six months. When writing your thesis, you must adhere to the layout guidelines of our working group, for which we will provide you with appropriate templates:
