8° Paperback. Condizione: Sehr gut. 258 S. In this study, samples were selected with respect to their layer charge and morphology. Sixteen bulk materials were pre-selected, which contained either swellable clay minerals or non-swelling clay minerals. One topic of this work was a comprehensive determination of layer and edge char…

8° Paperback. Condizione: Sehr gut. 293 S. The efficacy of cardiac resynchronization therapy (CRT) through biventricular pacing (BVP) has been demonstrated by numerous studies in patients suffering from congestive heart failure. In order to achieve a guideline for optimal treatment with BVP devices, an automated non-invasive str…

8° Paperback. Condizione: Sehr gut. 116 S. Heart disease is a leading cause of death worldwide. Straightforward information about the cardiac electrophysiology can help to improve the quality of diagnosis of heart diseases. The inverse problem of electrocardiography and the intracardiac catheter measurement are two ways to get a…

8° Paperback. Condizione: Wie neu. 131 S. Process optimization was conducted for the conversion of the aggragate-building substrate di-rhamnolipid to mono-rhamnolipid by Alpha-L-rhamnosidase from Penicillium decumbens and resulting in: (I) selection of optimal reaction conditions for enzyme activity and stability, (II) modeling…

8° Paperback. Condizione: Sehr gut. 220 S. In the scope of this thesis world's first robot system was developed, which facilitates osteotomy using laser in arbitrary geometries with an overall accuracy below 0.5mm. Methods of computer and robot assisted surgery were reconsidered and composed to a workflow. Adequate calibration a…

8° Paperback. Condizione: Sehr gut. 74 S. Origamis (also known as square-tiled surfaces) are Riemann surfaces which are constructed by glueing together finitely many unit squares. By varying the complex structure of these squares one obtains easily accessible examples of Teichmüller curves in the moduli space of Riemann surfaces…

4°, Paperback. Condizione: Sehr gut. 271 S. Der Erstellungsaufwand multimedialer Lernangebote kann durch die Wiederverwendung bestehender Materialien deutlich reduziert werden. Wie aber kann das Auffinden solcher wiederverwendbaren Lernressourcen unterstützt werden? Der Autor stellt ein Retrieval-Verfahren vor, das SCORM-basiert…

8° Paperback. Condizione: Sehr gut. 152 S. This book addresses the identification of the shape of penetrable periodic media by means of scattered time-harmonic waves. Mathematically, this is about the determination of the support of a function which occurs in the governing equations. Our theoretical analysis shows that this prob…

8° Paperback. Condizione: Sehr gut. 134 S. The energetic use of biomass can provide solutions for the growing worldwide demand for energy and fuel. This book contains the contributions for the final workshop of the "Biociclo" research exchange between the Universidad de Concepción and the Universität Karlsruhe. It reflects inter…

8° Paperback. Condizione: Sehr gut. 153 S. In this thesis two probabilistic model-based estimators are introduced that allow the reconstruction and identification of space-time continuous physical systems. The Sliced Gaussian Mixture Filter (SGMF) exploits linear substructures in mixed linear/nonlinear systems, and thus is well-…

8° Paperback. Condizione: Wie neu. 131 S. This computational study investigates diverse bonding situations in nanostructures (carbon nanotubes, fullerenes, metal compounds) spanning a broad range of energies. Weak, dispersive interactions and covalent metal-ligand and metal-metal bonding are examined. The results of efficient de…

8° Paperback. Condizione: Sehr gut. 134 S. Stresses in the vicinity of the crack tips are responsible for failure of crack-containing components. The singular stress contribution is characterised by the stress intensity factor K, the first regular stress term is represented by the so-called T-stress. Whereas in the main volume,…

8° Paperback. Condizione: Wie neu. 142 S. This book discusses the mechanical and opto-electronic design of laser spectrometers for measuring two very important atmospheric gases, namely water vapor and its isotopic ratios, and formaldehyde. For measuring water vapor, shot-noise limited sensitivity has been achieved by a careful…

4°, Paperback. Condizione: Sehr gut. 173 S. Automatic transcription of lectures is becoming an important task. Possible applications can be found in the fields of automatic translation or summarization, information retrieval, digital libraries, education and communication research. Ideally those systems would operate on distant…

8° Paperback. Condizione: Sehr gut. 176 S. In dieser Arbeit werden folgende Punkte, zum Teil erstmalig, untersucht:- Entwicklung eines analytischen Modells zum schnellen Design von Rotman-Linsen- Rotman-Linsen im Zeitbereich bei transienten Eingangssignalen- Leistungsaufteilung innerhalb einer Rotman-Linse- Untersuchung der Rotm…

8° Paperback. Condizione: Sehr gut. 172 S. This thesis analyzes the impact of various loss processes on the threshold current density of organic semiconductor laser diodes by numerical simulation. Design concepts based on organic double-heterostructures are evaluated and design rules are derived which can be used in order to red…

8° Paperback. Condizione: Sehr gut. 237 S. Monte Carlo radiation transport codes were used with virtual models of in vivo measurement equipment. Software was coded to handle memory intensive anthropomorphic voxel models for simulation of measurement scenarios. Tools, methods and models have been validated. Various parameters hav…

8° Paperback. Condizione: Sehr gut. 145 S. This work presents three new quantitative methods for magnetic resonance imaging. A method for simultaneous mapping of B1 and T1 (MTM) is developed and validated.

8° Paperback. Condizione: Sehr gut. 155 S. Due to their high energy conversion efficiencies and low emissions, Solid Oxide Fuel Cells (SOFCs) show promise as a replacement for combustion-based electrical generators at all sizes. Further increase of SOFC efficiency can be achieved by microstructural optimization of the oxygen-ion…

8° Paperback. Condizione: Sehr gut. 265 S. Throughput in manual order picking systems with narrow aisles suffers from congestion as pickers cannot pass each other. Only few models incorporate congestion but they have very strict assumptions. In this work, queueing theory is used to analyze systems with traversal routing as well…
