Extensive attachments of your work may need to be uploaded in a separate file. Shaker , Aachen [Dissertation]. The novel approach to the synthesis of Cu-doped ZnO resulted in homogeneously distributed copper ions in ZnO matrix. A high charge injection capacity permits an energy-efficient electrical stimulation with parameters not critical for biological tissue. A high-order Discontinuous Galerkin solver for incompressible and low-Mach number flows.

For this purpose, vertically aligned carbon nanotubes, unordered carbon nanotubes as well as vertically aligned gold nanowires or submicronwires are used as microelectrode material. Shaker , Aachen [Dissertation]. The heat transfer during drop impingement is of particular importance in spray cooling which is a promising technology for the removal of high heat fluxes at a small temperature difference. Which supplements and annexes are permitted? Innerhalb der letzten Jahre hat sich der algebraische Ansatz zur Formalisierung von Graphtransformationssystemen zu einem umfassenden Rahmenwerk zur Modellierung, Analyse und Verifikation entwickelt. TU-Darmstadt , Darmstadt [Habilitation] , For this system class, the problem of inverse reinforcement learning is discussed and a meta learning algorithm is devised that makes explicit use of the system symmetries.

Mikrointegrierte Nanostrukturen mit hohem Aspektverhältnis als neuronale Schnittstelle

Thus the microelectrodes and the conductive traces are made of doped poly-silicon and the electrical insulation layer darmstxdt the conductor traces is made of silicon dioxide. The larger such an electrode, the more cells will be stimulated or activity of multiple cells detected simultaneously.

Alle vier konzipierten und realisierten nano- bzw. Even though the focus of this thesis is on dossertation droplets, also the interaction of individual droplets during their impingement is addressed briefly.

PhD Thesis

Other than most existing approaches, the proposed methodology naturally handles periodic tasks and situations where the intentions of the expert change over time. We examine the file formally and give you feedback.

Moreover, many studies on pool boiling heat transfer have demonstrated that the evaporation at the 3-phase contact line, where the solid, liquid, and gas phase meet, might contribute significantly to the overall heat transfer. You register in TUprints, upload your file and fill in the metadata. Moreover, to assess its potential for analyzing real world applications, ukb prototype is applied to analyze a case study from the enterprise modeling domain.

The integration of primitive data attributes within the graph structure is indispensable to model almost all realistic systems, since they combine the structural aspects of a system with data aspects such as computations of values.

First, a nonparametric inference framework is developed to capture the behavior of the expert at the policy level. Additionally, we verify the well-known results for the static verification of consistency constraints, conflict detection, and conflict resolution by confluence analysis within our framework.

Electrochemical properties of the electrodes are examined by cyclic voltammetry and electrochemical impedance spectroscopy. Print Impressum Privacy Policy. Print Impressum Privacy Policy. This thesis presents new results in this field of research. The application in such a biological environment requires the use of exclusively biocompatible materials.

Our first contribution is a new computational framework for SMC with real values which are stored in a logarithmic encoding. Further information on the habilitation process can be found on the website of Department II.

Impedance characteristics of the various microelectrodes are simulated and evaluated in MATLAB applying an electrical equivalent circuit of the interface between an electrode and an electrolyte. However PEDOT dissolves partially after 24 hours under ultrasonic treatment and the impedance is increased. It addresses both the theoretical aspects of behavioral modeling — like the darmwtadt of appropriate task representations — and the practical difficulties regarding algorithmic implementation.

Peter and Weigand, Prof. For this system class, the problem of inverse reinforcement learning is discussed and a meta learning algorithm is devised that makes explicit use of the system symmetries. In contrast to existing approaches, the proposed framework reflects more closely the attribute handling of current state of the art graph transformation dissertatiin. Alternative Abstract Language The interface between microelectrodes and neural tissue is essential for many biomedical applications, such as cochlear implants, retinal implants, deep brain stimulation, electrocorticography or spinal cord stimulation which is applied for the suppression of chronic pain.

A good agreement of the model predictions to the measurements is achieved.
