Using in-car speech interaction systems has become increasingly popular. However, the cognitive workload resulting from this and its consequences for the driver are not yet fully understand. This thesis therefore aims to better understand the consequences of driver cognitive workload regarding performance, subjective evaluation and physiological changes and to identify suitable non-intrusive ph...

Zwischen Antisemitismus und Apartheid

Plass, Hanno (2017)

Die überproportionale Beteiligung jüdischer Südafrikaner am Kampf gegen die Apartheid über fast fünf Jahrzehnte ist erklärungsbedürftig. Ihre Bereitschaft, das eigene Leben für die Befreiung vom rassistisch begründeten weißen Minderheitsregime zu riskieren, war keineswegs selbstverständlich. Die Begründungen und Biographien der Aktivisten lassen jedoch eindeutige Rückschlüsse und Erklärungen au...

Southern promises: a snapshot of the microbiology research landscape in South America based on bibliometric data

Nai, Corrado (2017-09)

Scientists have a single currency for productivity and impact: published articles. In an effort to map the global research landscape in microbiology, and to obviate the current lack of bibliometric analysis in the field, FEMS—the Federation of European Microbiological Societies—generated a dataset encompassing an exhaustive, worldwide list of microbiology studies for 2013–14, which further incl...

Ex vivo Charakterisierung von humanen Autoantigen-spezifischen CD4+ T-Zellen mit Fokus auf Multiple Sklerose

Gamradt, Stefanie (2017)

Trotz intensiver Forschung ist unklar, ob Myelin-reaktive CD4+ T-Zellen in der Pathogenese der Multiplen Sklerose (MS) eine relevante Rolle spielen. Ein Grund dafür ist das Fehlen einer Methode für ihre direkte Analyse. In dieser Arbeit ist es mit Hilfe der magnetischen Anreicherung von spezifisch-aktivierten CD154+ konventionellen und CD137+ regulato-rischen T-Zellen in Kombination mit multipa...

Metabolic engineering of O-acetyl-L-homoserine sulfhydrylase and Met-biosynthetic pathway in Escherichia coli

Ma, Ying (2017)

The application of non-canonical amino acids (ncAAs) offers a new approach for the post-translational modification of proteins [1–4]. Especially the incorporation of ncAAs containing different functional groups such as azides, alkynes or olefins, provides a covalent site on the protein. Subsequently the attachment of other small molecules (fluorescent dye, biotin, sugar, PEG, etc.) brings more ...

Learning representations with neuromodulators

Holca-Lamarre, Raphael (2017)

Neurons in the cortex and in multi-layer perceptrons (MLPs) represent inputs as patterns of activity. In both systems, the nature of a neural representation carries important consequences and, accordingly, the mechanisms guiding representation learning are of great relevance. In MLPs, the most widespread learning method is the error-backpropagation algorithm. Although functionally effective, th...

CE_Method. A MATLAB function for calculating the part load behaviour of absorption chillers and heat pumps based on (C)haracteristic (E)quations

Albers, Jan (2017-09-26)

The algorithm CE_METHOD calculates the part load behaviour of single stage absorption chillers and heat pumps explicitly as function of inlet temperatures and flow rates. For the characterisation of the chiller or heat pump the heat transfer capabilities (i.e. the UA-values) of five heat exchangers (Desorber, Evaporator, Condenser, Absorber and Solution heat exchanger) have to be known.

Anaerobic transformation of brominated aromatic compounds by Dehalococcoides mccartyi strain CBDB1

Yang, Chao (2017)

Brominated flame retardants are widely used compounds for fire safety in our daily life. Many of them have been reported to be toxic to humans and identified as environmental contaminants. Dehalococcoides mccartyi strains are well known for their dependence on organohalide respiration as an energy conserving process and have therefore been intensively studied. So far, much less investigations w...
