- This document describes the technical layout and the expected performance of the Straw Tube Tracker (STT), the main tracking detector of the PANDA target spectrometer. The STT encloses a Micro-Vertex-Detector (MVD) for the inner tracking and is followed in beam direction by a set of GEM stations. The tasks of the STT are the measurement of the particle momentum from the reconstructed trajectory and the measurement of the specific energy loss for a particle identification. Dedicated simulations with full analysis studies of certain proton-antiproton reactions, identified as being benchmark tests for the whole PANDA scientific program, have been performed to test the STT layout and performance. The results are presented, and the time lines to construct the STT are described.

- The paper presents a multimodal conversational interaction system for the Nao humanoid robot. The system was developed at the 8th International Summer Workshop on Multimodal Interfaces, Metz, 2012. We implemented WikiTalk, an existing spoken dialogue system for open-domain conversations, on Nao. This greatly extended the robot's interaction capabilities by enabling Nao to talk about an unlimited range of topics. In addition to speech interaction, we developed a wide range of multimodal interactive behaviours by the robot, including face-tracking, nodding, communicative gesturing, proximity detection and tactile interrupts. We made video recordings of user interactions and used questionnaires to evaluate the system. We further extended the robot's capabilities by linking Nao with Kinect.

Open-Domain Conversation with a NAO Robot

Konferensbidrag (refereegranskat)abstract
- In this demo, we present a multimodal conversationsystem, implemented using a Nao robot and Wikipedia. The system was developed at the 8th International Workshop on Multimodal Interfaces in Metz, France, 2012. The system is based on an interactive, open-domain spoken dialogue systemcalled WikiTalk, which guides the user through conversations based on the link structure of Wikipedia. In addition to speech interaction, the robot interacts with users by tracking their faces and nodding/gesturing at key points of interest within the Wikipedia text. The proximity detection capabilities of the Nao,as well as its tactile sensors were used to implement context-based interrupts in the dialogue system.

Low Mach-number collisionless electrostatic shocks and associated ion acceleration

Tidskriftsartikel (refereegranskat)abstract
- The existence and properties of low Mach-number electrostatic collisionless shocks are investigated with a semi-analytical solution for the shock structure. We show that the properties of the shock obtained in the semi-analytical model can be well reproduced in fully kinetic Eulerian Vlasov-Poisson simulations, where the shock is generated by the decay of an initial density discontinuity. Using this semi-analytical model, we study the effect of electron-to-ion temperature ratio and presence of impurities on both the maximum shock potential and Mach number. We find that even a small amount of impurities can influence the shock properties significantly, including the reflected light ion fraction, which can change several orders of magnitude. Electrostatic shocks in heavy ion plasmas reflect most of the hydrogen impurity ions.
