User-centred adaptive spoken dialogue modelling
(Universität Ulm, 2015)
This dissertation investigates novel concepts and methods for the automatic recognition of dynamic user properties using statistical supervised learning and for the integration of these properties into the dialogue management ...
Automotive radar interference mitigation by reconstruction and cancellation of interference component
Beitrag zu einer Konferenz
(Universität Ulm, 2015)
Automotive radar interference is an issue arising with the increasing amount of radar systems in automotive scenarios. Interference can influence the functionality of a radar system, e.g. decrease its detection capability. ...
Theoretical aspects of overlapping genes
This thesis investigates theoretical aspects of overlapping genes in prokaryotes. Overlapping genes are protein-coding sequences that are encoded in different reading frames of the same DNA region, such that the sequences ...
Situation- and user-adaptive dialogue management
In the sea of human machine interaction a growing trend to personalize the interaction experience has been surfacing over the last decades. Human machine interfaces have more and more become companion systems which on the ...
Equalization and decoding - a continuous-time dynamical approach
The human brain has the capability to organize the neurons (experience-adapted connections) to perform specific tasks faster and much more efficient than any digital computer in existence today. Pattern recognition and ...
Epitaxial growth and characterization of coaxial GaN/InGaN/GaN nano-structures
The development of a fabrication process for highly crystalline and position controlled GaN based nano- and submicron-structures together with the respective coaxial InGaN quantum well overgrowth was the focus of this ...
Multi-functional Monolithic ICs for 94GHz Transmitters on Silicon
The atmospheric transmission window at 94 GHz is an established allocation for radar sensors. This wavelength can penetrate fog, clouds, or textile materials and offer good spatial resolution. Applications are indicated ...
Impulse-radio ultra-wideband circuits for communication and radar sensing
This dissertation presents a differential UWB chipset for communication and medical sensing. The key components are UWB impulse generators, LNA, correlator and energy detection circuit. A quenched-oscillation concept is ...
Increasing the bandwidth efficiency of OFDM-MFSK
Noncoherent detection is very attractive when transmitting over fast time-variant frequency selective fading channels, since it is difficult or even impossible to obtain reliable channel state information. OFDM-MFSK and ...
Simple Temporal Networks with Partially Shrinkable Uncertainty (extended version)
The Simple Temporal Network with Uncertainty (STNU) model focuses on the representation and evaluation of temporal constraints on time-point variables (timepoints), of which some (i.e. contingent timepoints) cannot be ...
