Implementing of a Ptolemy II plug-in for modeling and simulatuin of LTI-hybrid automata.

Responsible: Matthias Werner

Hybrid systems are gaining on popularity in the last decade and are used to model complex behaviors of cyber-physical systems. Many tools exist for modeling and analysis of hybrid models, such as Simulink, Modelica, Ptolemy, UPPAAL, etc. Research should provide an exhaustive list and a comparison of these tools with one another in terms of performance (run-times, scalability).

Isabelle / HOL

Responsible: Matthias Werner

The Isabelle/HOL tool is one of the internationally leading tools for proving correctness of computer systems (theorem prover). E.g., the correctness proof of the seL4 kernel was done by the use of Isabelle. For this seminar topic, the student should give a introduction to Isabelle/HOL and the foundation behind, as well as demonstrate its practical usage by verifying a given protocol.

Python runtime on the base of Forth

Responsible: Matthias Werner

Forth is a syntx-less, very machine-oriented programming language with a bare-metal run-time system (i.e. without OS). The task is to develop an interpreter for Python byte code on top of a Forth system on a embedded board.

Adaptive vs. Dynamic?

Responsible: Christine Jakobs

This seminar topic should give an overview about the definitions for the terms adaptive and dynamic. The definitions differ between different research areas. Therefore the question is how they are defined in MDD, SE, embedded systems, CPS, real-time systems and operating systems. Where do the definitions differ and how can they be mapped?

Analysis of safety- and security-mechanisms onto the architecture

Responsible: Christine Jakobs

Safety- and security-mechanisms kann be divided regarding their possible impact on the software-architecture. Fault tolerance mechanisms for example may assume a special system design. The task is to evaluate existing literature from fault tolerance research and abstract the ideas to include general safety- and security-mechanisms.

Coordination Models and Languages

Responsible: Martin Richter

Coordination languages allow the programmer to describe concurrent and distributed computations through the concept of "coordination".It allows to integrate many possibly heterogeneous components by providing distribution transparency.The set of all components forms a single application in a way, that it can be executed in a distributed and parallel fashion. Papadopoulos and Arbab give an overview of different coordination languages in "Coordination Models and Languages".It will be your task to review the paper and present the different coordination models and languages, what differentiates them, what their benefits and drawbacks are and to present at least one use-case per paradigm.

RoboCup - Coordination Models

Responsible: Martin Richter

Since 1997 the RoboCup (Robot Soccer World Cup) is held, where different teams of researchers and students are competing in numerous leagues. A game of robot soccer is always played between two equally sized sets of robots, ranging from five to eleven robots per team. Depending on the league, the game is either simulated or conducted physically with real robots.If the game is played physically, multiple mobile robots perceive their environment through sensors (e.g., recognizing enemy player positions) and influence it through actuators (e.g., kicking the ball), a team of robots is classified as a mobile cyber-physical system. Coordination is one of the main challenges for cyber-physical systems, as multiple heterogeneous execution units might have to cooperate to reach a common goal. To ensure a safe and timely operation, the planning of which units fulfill which tasks at which point in time is critical.As a RoboCup team has to be coordinated to conduct complex moves, coordination models are employed. Such models encompass the choice of varying tasks for different robots to reach a common main-goal or possibly multiple sub-goals. Your task will be to review different coordination models, used in the RoboCup.

RoboCup – World Modeling

Responsible: Martin Richter

Since 1997 the RoboCup (Robot Soccer World Cup) is held, where different teams of researchers and students are competing in numerous leagues. A game of robot soccer is always played between two equally sized sets of robots, ranging from five to eleven robots per team. Depending on the league, the game is either simulated or conducted physically with real robots.If the game is played physically, multiple mobile robots perceive their environment through sensors (e.g., recognizing enemy player positions) and influence it through actuators (e.g., kicking the ball), a team of robots is classified as a mobile cyber-physical system. Achieving a consistent view of the environment in cyber-physical systems is of paramount importance, to allow the different execution units to collaborate and tackle common tasks.As a RoboCup team has to decide on which moves to take, the state of the game (e.g., player positions) has to be evaluated continuously. For this, a virtual representation of the real world is required and data has to be exchanged between the robots. Your task will be to review different models, which are concerned with the virtual representation of the real world in the RoboCup.

RoboCup - Simulators

Responsible: Martin Richter

Since 1997 the RoboCup (Robot Soccer World Cup) is held, where different teams of researchers and students are competing in numerous leagues. A game of robot soccer is always played between two equally sized sets of robots, ranging from five to eleven robots per team. Depending on the league, the game is either simulated or conducted physically with real robots. If the game is simulated (i.e., in the 2D-simulation and 3D-simulation leagues), a soccer simulation platform is utilized. Your task will be to review the current simulation platform (either 2D or 3D), used in the RoboCup.

Using Petri nets to model communication in HPC

Responsible: Theresa Werner

For some time now, ressource management and communication are big topics in High Performance Computing (HPC). Up until now, speed-up has been achieved by faster processors or scalable applications, but HPC is now mostly communication-bound. Timed Petri nets can model communication in networks. For this work, a specific communication algorithm shall be modeled with timed petri nets (using one up to three different hardware configurations). In cooperation with Supercomputing Centre Jülich, Germany, a comparison to the real communication time of the algorithm can be made and discussed.

Component Risk Analysis for Automotive Systems

Responsible: Christine Jakobs

The focus of the research internship is on the implementation of the developed component security risk analysis method. Therefore, the student gets the method description and relevant input data. The task is to read and understand the method description and implement the method in a proper programming language, e.g., Python. The research part of the task consists of researching appropriate implementation schemes and missing information for the technique.

Framework for Simulation and Performance Analysis of Clock Synchronization Algorithms

Responsible: Jafar Akhundov

The task is to create a framework for simulation and performance analysis of diverse clock synchronization algorithms. Implementation language/tool is irrelevant. To achieve this distributed systems must be parametrized with respect to clock synchronization. As a basis an existing master thesis can be used. The context and big goal of the work is to automatically generate synchronization modules for parametrized spacecraft systems.

Umsetzung von Programmierparadigmen der Objektorientierung zur Realisierung von Function-as-a-Service Systemen mit Microservices

Responsible: Marcus Hilbrich

Micro Services lag abstraction methods. E.g, In case multiple services are needed to process a single transaction, the concept of the transaction is not really present in the code of the services. In a first step a tool was created and evaluated to allow to write the transaction as an object oriented like class and generate services based on the methods of the class. This is not yet a general solution and needs extensions. 1) using a more general programming language (e.G. Java) 2) support additional OO concepts (generalization, polymorphy, …) 3) stronger evaluation 4) multi language support 5) multi Cloud support
