Experiment Video for Model Predictive Path-Following Control of a Quadrotor
No full textThe provided video shows an experimental result of a Model Predictive Path-Following Controller (MPPFC) applied to a Crazyflie Quadrotor.
The objective is to fly along the lemniscate path.
The lemniscate is defined as a time-independent geometric curve, parameterized by a so-called timing law.
Based on this, the MPPFC generates a dynamically feasible trajectory from the provided path in accordance with state and input constraints.
Consequently, the generated trajectory is then tracked by the Quadrotor by the MPPFC.
Therefore, the MPPFC combines trajectory generation and tracking into a single framework.
A quantitative analysis of this approach, as well as further results and details of the experiment can be found in the related publication associated with this video

Code for EchoTables (IKILeUS)
No full textEchoTables is an innovative accessibility tool developed as part of the IKILeUS project at the University of Stuttgart. It is designed to improve the usability of tabular data for visually impaired users by converting structured tables into concise, auditory-friendly textual summaries. Traditional screen readers navigate tables linearly, which imposes a high cognitive load on users. EchoTables alleviates this issue by summarizing tables, facilitating quicker comprehension and more efficient information retrieval.
Initially utilizing RUCAIBox (LLM), EchoTables transitioned to Mistral-7B, a more powerful open-source model, to enhance processing efficiency and scalability. The tool has been tested with widely used screen readers such as VoiceOver to ensure accessibility. EchoTables has been adapted to process diverse data sources, including lecture materials, assignments, and WikiTables, making it a valuable resource for students navigating complex datasets

Data for: Lagrangian Sensor Particles for detecting hydrodynamic heterogeneities in industrial bioreactors - experimental analysis and Lattice-Boltzmann simulations
No full textThis DaRUS repository entails the raw files and result files (excluding MATLAB code files, see Gitlab repository including documentation) for the publication "Lagrangian Sensor Particles for detecting hydrodynamic heterogeneities in industrial bioreactors: experimental analysis and Lattice-Boltzmann simulations" in the journal "Chemical Engineering Journal Advances".
Abstract:
This study analyzes trajectories of three particle types in an industrial-scale bioreactor, equipped with a Rushton turbine and a pitched blade turbine, to characterize hydrodynamic compartments. The trajectories obtained from measurements with Lagrangian Sensor Particles (LSP,exp) are compared to those generated by Lattice-Boltzmann large eddy simulations (LB LES). The latter method is used to reproduce analogous simulated LSPs (LSP,sim) as resolved particles. Additionally, for benchmarking purposes, massless tracer particles (tracer) are incorporated to accurately represent fluid flow dynamics. Discrepancies in the axial probability of presence and velocity between LSP,exp and LSP,sim likely stem from differences in mass distribution, density, number of particles, and ratio of particle size to grid. A necessarily high LSP,sim volume fraction in LB LES leads to increased collisions and clustering, negatively impacting flow dynamics, and reducing turbulent kinetic energy by at least . Circulation and residence time distributions for the three types of particles identify three hydrodynamic compartments within the bioreactor, validated by local mixing time distributions.The ratio of overall average circulation time to global mixing time is for LSP,exp, which largely corresponds to literature results. A theoretical LSP size of is estimated to be flow following on micro-scale in the bulk phase, if a Stokes number of is assumed. However, Stokes number estimations confirm that LSP,exp are capable to follow flow patterns on the meso-scale and macro-scale with and , respectively. Hence, hydrodynamic structures at length scales greater than or equal to the size of the impeller can be investigated by current state-of-the-art LSPs, which proves their technological readiness for industrial bioreactors.</p
