Fahrerintentionserkennung und Kursprädiktion mit erweiterten maschinellen Lernverfahren
Dissertation
Vorausschauende Fahrerassistenzsysteme benötigen eine präzise Kenntnis über den zukünftigen Verlauf der Verkehrssituation; dieser kann in Echtzeitsystemen nur anhand vorheriger Beobachtungen geschätzt werden. Im ...
Algebraic soft- and hard-decision decoding of generalized Reed--Solomon and cyclic codes
Dissertation
Two challenges in algebraic coding theory are addressed within this dissertation.
The first one is the efficient hard- and soft-decision decoding of Generalized Reed--Solomon codes over finite fields in Hamming metric. ...
Object-aware process management
Dissertation
Process management systems (PrMS) offer promising perspectives for a more flexible and efficient process execution. However, for many process-aware application systems, the underlying process logic is still hard-coded. As ...
Investigation of mm-wave imaging and radar systems
Dissertation
In the last decade, microwave- and millimeter-wave systems have gained importance in civil and security applications. Due to an increasing maturity and availability of circuits and components, these systems are getting ...
On effective and efficient mutation analysis for unit and integration testing
Dissertation
Software testing is the most common technique to verify that a program meets certain quality standards. Sufficient manual testing is not only time consuming but also an error-prone task. Additionally, due to the rapidly ...
The thermal instability of nanocrystalline materials - an experimental case study of microstructural evolution in ball-milled iron
Dissertation
Manifesting superior properties compared to their coarser-grained conventional counterparts, nanocrystalline materials are attracting growing attention in the areas of basic research and industrial application. However, ...
Kontextgestützte Fußgängerklassifikation für ein Fahrzeug-Nachtsichtsystem
Dissertation
Durch den Einsatz von Nachtsichtsystemen mit Fußgängererkennung in modernen Fahrzeugen soll die Anzahl tödlicher Unfälle bei Nacht minimiert werden. Hierfür wird die Klassifikationsaufgabe im Bild üblicherweise über lokale ...
Solving the ridematching problem in dynamic ridesharing
Dissertation
Among the transportation demand management strategies that can be used to reduce the power consumption, air pollution and traffic congestion is the ridesharing. A flexible form of ridesharing in which a rideshare can be ...
Fehlertoleranz in einem verteilten Betriebssystem mit transaktionalem Speicher
Dissertation
Creating checkpoints of a distributed cluster operating system is a non-trivial task, as special coordination between cluster nodes is necessary to cope with the domino effect. This additional coordination effort of ...
Technology and characterization of InAlN/GaN FETs
Dissertation
In this work the lattice matched In0.17Al0.83N/GaN heterostructure was investigated using DC, small signal and large signal characteristics of planar HEMTs. The study included heterostructures with variable barrier ...
