"A Multimodal Scheduler for Synchronized Humanoid Robot Gesture and Speech",
In: Book of Extended Abstracts of the 9th International Gesture Workshop, pp. 64-67, 2011.
Abstract
In order to engage in natural and fluent human-robot interaction, humanoid robot companions must be able to produce speech-accompanying non-verbal behavior including hand and arm gestures. In human communication, gestures are considered an integral part of the human thinking process. Accordingly, they are found to be finely synchronized with the accompanying linguistic affiliate [McNeill 2002]. Many researchers have emphasized the importance of t...

"Gaussian Process Implicit Surfaces for Shape Estimation and Fluent Grasping",
Proceedings of the IEEE International Conference on Robotics and Automation, 2011.
Abstract
The choice of an adequate object shape representation is critical for efficient grasping and robot manipulation. A good representation has to account for two requirements: it should allow uncertain sensory fusion in a probabilistic way and it should serve as a basis for efficient grasp and motion generation. We consider Gaussian process implicit surface potentials as object shape representations. Sensory observations condition the Gaussian proces...

"Generalization performance of spetro-temporal speech features",
Proceedings of DAGA, 2011.
Abstract
We previously introduced Hierarchical Spectro-Temporal (HIST) features, which, in contrast to conventional spectral features as MFCCs or RASTA-PLP features, are able to model spectro-temporal modulations. We could show that a combination of HIST features with either MFCCs or RASTA-PLP features significantly improves recognition performance in a noisy digit recognition task. HIST features consist of two hierarchical layers where the corresponding ...

"Computational Audiovisual Scene Analysis for Dialog Scenarios",
IROS 2011 Workshop on Cognitive Neuroscience Robotics, 2011.
Abstract
We introduce a system for Computational Audio- Visual Scene Analysis (CAVSA) with a focus on human-robot dialogs in multi-person environments. The general target of CAVSA is to learn who is speaking now, where the speaker is, and whether the speaker is talking to the robot or to other persons. In the application specied in this paper, we aim at estimating the number and position of speakers using several auditory and visual cues. Our test applica...

"Invariant Object Recognition and Pose Estimation with Slow Feature Analysis",
Neural Computation, 2011.
Abstract
Primates are very good at recognizing objects independently of viewing angle or retinal position and outperform existing computer vision systems by far. But invariant object recognition is only one prerequisite for successful interaction with the environment. An animal also needs to assess an object’s position and relative rotational angle. We propose here a model that is able to extract object identity, position, and rotation angles. We demons...

"Task- and Knowledge-Driven Scene Representation",
TU Ilmenau, 2011.
Abstract
In this thesis a flexible system architecture is presented along with an attention control mechanism allowing for a task-dependent representation of visual scenes. Contrary to existing approaches, which measure all properties of an object, the proposed system only processes and stores information relevant for solving a given task. The system comprises a short- and long-term memory, a spatial saliency algorithm and multiple independent processing ...

"Aerodynamic Improvement of a Transonic Fan Outlet Guide Vane using 3D Design Optimization",
Proceedings of the ASME Turbo Expo, 2011.
Abstract
In this paper we follow the process of rapid design improvement for the fan outlet guide vane for a turbofan powering a very light jet. The small size of such engines leads to a low Reynolds number, resulting in flow-fields prone to boundary layer separation, causing significant losses in efficiency. This paper studies experimental testing in a scale rig, and numerical simulation using CFD, leading to the comparis...
