    Beschreibung: Radio communications in the range of 60 GHz enable multi-Gigabit/s network access in indoor environments. Due to the propagation characteristics of such signals only very short range radio transmission is feasible. In order to distribute these signals across large distances, analog transmission over optical fiber is considered. In this work, mode-locked laser diodes serve as optoelectronic oscillators for the generation of such signals. Their system-relevant properties are studied in detail.

    Beschreibung: A predictive tracking approach and a novel method for visual motion compensation are introduced, which accurately reconstruct and compensate the deformation of the elastic object, even in the case of complete measurement information loss. The core of the methods involves a probabilistic physical model of the object, from which all other mathematical models are systematically derived. Due to flexible adaptation of the models, the balance between their complexity and their accuracy is achieved.

    Beschreibung: The aim of this work was to identify the patterns that can induce heating around implanted cardiac pacemakers during MRI and to develop strategies to counteract them. Two approaches were taken: computer simulations of the occurring electromagnetic field distributions and in-vitro experiments using phantoms in real MRI devices, both for conventional bore-hole and new open MRI systems. Using the open MRI, the observed heating could be reduced significantly.

    Beschreibung: The gas phase direct hydroxylation of benzene into phenol with hydrogen and oxygen, as initially described by Niwa in 2002, was realized in a newly developed double-membrane reactor. In the concept described by Niwa, a dense Pd membrane is used for the (safe) dosage of dissociated hydrogen species into the tubular reaction zone, where it reacts with gas phase oxygen to form surface species capable of directly converting benzene into phenol in a single-step process.

    Beschreibung: August Ludwig Hülsen (1765-1809) was a contributor to the emergence of German idealism. Notwithstanding, his name and works are up to this day almost entirely unknown to most scholars in the field. This monograph discusses the historical importance of Hülsen's Prüfung der von der Akademie der Wissenschaften zu Berlin aufgestellten Preisfrage: Was hat die Metaphysik seit Leibniz und Wolf für Progressen gemacht? (1796), his only book, for the emergence of German idealism, especially the thought of Reinhold and Fichte during the 1790's. The usual way of focusing on the Wissenschaftslehre, and hence, on the emergence of German idealism, is as a “response” of Fichte to the skeptical objections of Schulze-Aenesidemus to Reinhold's early Elementarphilosophie. This “response”, as Fichte himself recognized in 1798, was far from complete. Hülsen, a Fichtean thinker, restructured and regrounded those aspects of Reinhold's system that Fichte left intact: in particular, Reinhold's almost forgotten approach to the rational history of philosophy. In 1797, Hülsen's achievement prompted Fichte's recommendation of Hülsen's book in Annalen des philosophischen Tons as an introduction to his Wissenschaftslehre. This indicates that Fichte recognized Hülsen as a partner in the development of his incomplete system. Accordingly, the historical importance of Hülsen's book is that it completed Fichte's attempt to overcome Reinhold's standpoint and contributed to the emergence of German idealism.

As they can amplify forecast errors and project them onto the Rossby wave pattern, they are of high relevance for numerical weather prediction. This work elaborates on two aspects of WCBs in the context of ensemble forecasts: (1) sensitivities of WCBs to the representation of initial condition and model uncertainties, and (2) the role of WCBs for forecast error growth.

    Beschreibung: Fracture of storage particles is considered to be one of the major reasons for capacity fade and increasing power loss in Li-ion batteries. In this work, we tackle the problem by merging a coupled model of mechanical stress and diffusion of Li-ions with a phase field description of an evolving crack. The novel approach allows us to study the evolution of the Li concentration together with the initiation and growth of a crack in an arbitrary geometry and without presuming a specific crack path.

    Beschreibung: Bridge cranes are widely used as discontinuous material handling systems in industrial environments. The so-called crane bridge plays a central role in the overall construction. With increasing span widths and load capacities, the dimensions of the crane bridge also increase. The core of this work is the design and optimization of a new type of bridge crane system, which consists of individual segments and is eccentrically pretensioned by a tensile member.

Outcrops allow the analysis of depositional environments and diagenesis, thus an investigation of reservoir quality controls. A process-oriented approach is used to understand variability in a meander deposit, compaction and cementation behavior of lithofacies types during burial and the discrepancy between porosity and permeability values.

Building on such abstract structures renders the correctness results language-independent. To prove that they hold for a specific language, it remains to instantiate the framework with this language, which requires a formal semantics of this language in Isabelle/HOL. We show that formal semantics even for sophisticated high-level languages are realizable.

A deposition process for ten unit-cell thin films and a sub-µm patterning process were developed to enable high sensitivities. The detector response to THz exctiations and its electrical-field sensitivity were studied. This unique characteristic allows for the investigation of instabilities of the THz radiation emitted from synchrotron storage rings.

    Beschreibung: ECG recordings provide diagnostic relevant information on the de- and repolarisation sequences of the heart. A modification of the repolarisation sequence is assumed to cause Torsades de Pointes. Especially drug induced effects on the repolarisation processes are in focus, since some non-cardiac drugs have been associated with sudden cardiac death in the 1990s. The analysis of the ventricular repolarisation using a set of parameters depicting the morphology of the T-wave is introduced in this work. Therefore, new methods of fully automatic patient-specific QRS detection, beat classification and precise T-wave delineation are presented. Using these methods, medical studies are investigated regarding the modification of the T-wave by different compounds. Also the impact of the heart rate on the morphology of the T-wave is part of this research.The reliable identification of ventricular ectopic beats allows an analysis of the influence of these beats on subsequent heart beats. It turned out that the morphology of subsequent heart beats can significantly be changed. This might give new information on the proarrythmical risk of ventricular ectopic beats.

Further increase of SOFC efficiency can be achieved by microstructural optimization of the oxygen-ion conducting electrolyte and the mixed ionic-electronic conducting cathode. By application of nanoscaled thin films, the exceptionally high efficiency allows the realization of mobile SOFCs.

    Beschreibung: The main objectives of this book are (i) to investigate the electrochemical behavior and the analytical performance of a novel ultramicroelectrode array (UMEA); (ii) to assess the analytical parameters of square-wave anodic stripping voltammetric measurements (SWASV) using the UMEA; and (iii) to estimate the potential of the UMEA in developing decentralised analytical equipments for the determination of trace concentrations of heavy metals in natural waters. Surface analytical techniques (SEM, ESEM, and AFM) showed that the UMEA chips are of high quality in manufacture. Cyclic voltammetric and chronoamperometric experiments proved that the electrochemical behavior of the UMEA is dominated by the features characteristic for single microelectrodes.Chronocoulometry was found to be the most suitable method in generating the Hg-film of good quality. A new UMEA chip could be plated at least ten times, corresponding to about 500 measurements of trace metals in synthetic aqueous solutions. Using SWASV, detection limits of 〈0.1 ï¿g/l could be achieved for the metals (Pb, Cd). Precision and accuracy were found to be approx +/-10% of RSD.In natural waters, the results obtained with the UMEA sensor showed a reasonably good agreement with HR-ICP-MS analyses. Different experimental parameters were optimised and investigated. Interferences (e.g., DOC) were significantly reduced through medium exchange and standard addition. Ultrasonic bath proved to be very efficient in resurfacing electrodes in laboratory.The UMEA sensor shows a great potential in developing a portable trace metal analyzer. However, for in situ and on-site measurements, the protection of the UMEA sensor from fouling seems to be inevitable. In order to achieve a pure microelectrode behavior with the UMEA, increasing the ratio of interelectrode distance to electrode diameter is recommended for further developments.

    Beschreibung: This works describes an approach to lane-precise localization on current digital maps. A particle filter fuses data from production vehicle sensors, such as GPS, radar, and camera. Performance evaluations on more than 200 km of data show that the proposed algorithm can reliably determine the current lane. Furthermore, a possible architecture for an intuitive route guidance system based on Augmented Reality is proposed together with a lane-change recommendation for unclear situations.

    Beschreibung: In the second edition of the article a virtual heart modelsimulating the flow in the active left human ventricle andatrium is presented. Because in vivo myocardium data is notavailable, the movement of the active ventricle and its atriumis given by three-dimensional, time-dependent invivo image dataof a nuclear spin MRI tomograph. The passive part of the virtualheart model consists of a model aorta and of two-dimensionallymodelled heart valves. As the flow is actively driven by theventricle and atrium, a coupling off low and structure isnecessary to take into account the deviation of the aorta andthe closing and opening of the heart valves. This coupling isreplaced by the movement given by MRI tomograph and ultrasonicDoppler echocardiography, since we focus on the flow simulationin the left pumping ventricle. The flow simulation is performedby a validated commercial software package that uses the finitevolume method. The flow resistance of the circulation throughthe body is taken into account with a simplified circulationmodel. The article shows how the virtual heart model can be usedto predict flow losses and flow structures due to pathologicalventricle contraction defects. It provides as an example theflow simulation of an unhealthy human ventricle with ananeurysm. The flow structure and flow losses are consideredbefore and after surgery.

To handle the network's changing demands efficiently, the signal plan specification needs to be shifted from the design time to the run-time of a signal system. The generic observer/controller architecture proposed for Organic Computing facilitates this shift. A two-levelled learning mechanism optimises signal plans on-line while a distributed coordination mechanism establishes green waves in the road network.

    Beschreibung: Superconducting nanowire singe-photon detectors (SNSPD) are promising detectors in the field of applications, where single-photon resolution is required like in quantum optics, spectroscopy or astronomy. These cryogenic detectors gain from a broad spectrum in the optical and infrared range and deliver low dark count rates and low jitter times. This thesis improves the understanding of the detection mechanism of SNSPDs and intodruces new and promising multi-pixel readout concepts.
