"A data-driven methodology that includes the unfalsified control concept in the framework of fault diagnosis and isolation (FDI) and fault-tolerant control (FTC) is presented. The selection of the appropriate controller ...

"This thesis evaluates the technical, economic and environmental performance of a hydrogen fueled hybrid bus, which uses an internal combustion engine as a power unit. Results are compared to those of a conventional dies...

The usage of hydrogen in fuel cells gains more and more importance due to the need for emission-low alternatives in various technical areas. The focus of this work lies on the polymer electrolyte membrane fuel cell. One ...

We present a method for calculating the stability of reaction intermediates of electrochemical processes on the basis of electronic structure calculations. We used that method in combination with detailed density functio...

Abstract Polycyclic aromatic compounds (PACs) are known due to their mutagenic activity. Among them, 2-nitrobenzanthrone (2-NBA) and 3-nitrobenzanthrone (3-NBA) are considered as two of the most potent mutagens found in ...

The European demonstration fusion power plant (EU-DEMO) project intends to prove the commercial viability of nuclear fusion as a source of safe and clean energy. This fusion power plant will be fueled by a 1:1 deuterium-...

"This paper presents a technical, financial and environmental analysis of four different hybrid buses operated under Buenos Aires driving conditions. A conventional diesel bus is used as reference and three electric hybr...

With the increasing relevance of energy transition, synthetic fuels have arisen as an alternative to storage green energy. In the processing of this fuels, carbon monoxide is widely used. Understanding the behaviour of t...

"Reductions of fuel consumption and gas emissions count among the main advantages of hybrid electric vehicles (HEV). It is well known that the level of hybridisation has a large influence on the fuel consumption, the m...

Much effort has been expended in the aerospace industry in order to achieve the highest quality standards required for nowadays technical and environmental necessities. This involves the increase of specific power and ov...

The semiconductor ZnO has gained substantial interest in the research community in part because of its large exciton binding energy (60meV) which could lead to lasing action based on exciton recombination even above room...
