T1 (Bachelor/Master): Integrating vehicle collaboration concepts to AUTomotive Open System Architecture (AUTOSAR)

Description	Cooperative vehicles are no longer fiction. A key factor is the ability for vehicles to exchange information with their environment. Shared information has the potential to increase safety and efficiency of vehicle systems. Such collaboration concepts, however, have to be considered for current standards like AUTOSAR to enable a broad application. This seminar paper shall elaborate a related work analysis on the topic.

T2 (Bachelor/Master): Combination of Safety and Security Analysis

Description	In most cases in a safety analysis the influences of security problems are omitted or even forgotten. Because more and more systems are accessible from the outside of the system via maintenance interfaces, this missing security analysis is becoming a problem. New approaches for a combined assessement of safety and security should solve this problem. This seminar paper shall elaborate a related work analysis on the topic.

T3 (Bachelor/Master): The Role of Situation Awareness in Assuring Safety of Autonomous Vehicles

Description	Assuring safety of autonomous vehicles operating in an open environment requires reliable situation awareness, action planning and prediction of actions of other vehicles and objects. Factors that also have to be considered are certainty and completeness of available information and trust in information sources and other entities.

T14 (Master): Survey of concurrency related bugs and their consequences

Description	Now days, we increase the performance of processors by increasing the number of cores. Multicore, concurrent execution of software introduces a new type of software bugs – concurrency bugs. The aim of this work is to review literature and gather in a form of an FMEA table currently known concurrency bug types (e.g. race condition, priority inversion, atomicity violation, deadlock, live lock). For each bug, please provide a definition of conditions under which the bug occurs, with an example. The focus is on embedded domain.

T15 (Master): Survey of synchronization methods (synchronization primitives) in concurrent software

Description	Synchronization mechanisms aim to solve the challenge of concurrency. They are software artefacts intended to guarantee correctness of concurrent software execution. The aim of this study is to identify groups of concurrency synchronization mechanisms (e.g. Locks, non-locking data structures, platform - LET scheduling), and compare them according to their: Efficiency Prerequisites (HW, SW) What is each of them the most suitable for? This work should provide conceptual description of each synchronization mechanisms, with an example. If applicable, use an FMEA table.

T16 (Master): State of the practice: Data structures for non-locking synchronization of concurrent software

Description	Non-blocking synchronization is a synchronization mechanism where the suspension or failure of one thread does not block other threads from the execution of their task. The goal of this seminar is to evaluate state of practice, of non-blocking synchronization mechanisms in concurrent software. The seminar should give answers on these questions: List of non-locking synchronization frameworks List of open source, non-locking synchronization frameworks In which programming language are non-locking synchronization primitives implemented? Which hardware platforms support non-locking synchronization? Are additional libraries necessary for using non-locking synchronization in programming languages, such as C, C++, Java? Example code for standard non-locking synchronization primitives (e.g. que, stack)

T17 (Master): State of practice: MC/DC code coverage

Description	MC/DC is a coverage criteria used in safety critical software. This work should find available tools and approaches for achieving MC/DC criteria and group them, according to: What do they use as input (binary, source code, intermediate representation?) Do they change source code? Do they perform binary instrumentation? Do they analyse the execution trace? Any approach with LLVM? Any approach with gem5? Is the approach open source? This work should offer necessary definitions of terms used in the seminar, along with a set of examples for MC/DC nested decisions.
