Finding Phones Fast: Low-Latency and Scalable Monitoring of Cellular Communications in Sensitive Areas
The widespread availability of cellular devices introduces new threat vectors that allow users or attackers to bypass security policies and physical barriers and bring unauthorized devices into sensitive areas. These threats can arise from user non-compliance or deliberate actions aimed at data exfiltration/infiltration via hidden devices, drones, etc. We identify a critical gap in this context: the absence of low-latency systems for high-quality and instantaneous monitoring of cellular transmi…

Der Verfassungssprecher (!) der ÖVP, Wolfgang Gerstl, soll als Mitglied einer Bezirkswahlbehörde verbotenerweise die Kontaktdaten von fünf Privatpersonen verwendet haben, um sie zu kontaktieren und ihnen vorzuwerfen, eine andere Liste als die ÖVP zu unterstützen.
Ziel sei es laut StA Wien gewesen, das Antreten einer Liste zu verhindern.

Assessment of Hybrid RANS-LES and WALE Formulations for Wake and Resistance Prediction of the BB2 Submarine
Submarine hydrodynamics presents unique challenges in accurately predicting flow separation, wake structure, and resistance due to complex geometry and turbulent behaviour at high Reynolds (Re) numbers. Traditional Reynolds-Averaged Navier-Stokes (RANS) approaches are often limited in resolving unsteady flow structures and turbulence in the near and far regions. To address these limitations, hybrid RANS-LES models such as Detached Eddy Simulation (DES) and Large Eddy Simulation (LES) offer impr…

Off-Policy Reinforcement Learning with Anytime Safety Guarantees via Robust Safe Gradient Flow
This paper considers the problem of solving constrained reinforcement learning (RL) problems with anytime guarantees, meaning that the algorithmic solution must yield a constraint-satisfying policy at every iteration of its evolution. Our design is based on a discretization of the Robust Safe Gradient Flow (RSGF), a continuous-time dynamics for anytime constrained optimization whose forward invariance and stability properties we formally characterize. The proposed strategy, termed RSGF-RL, is a…

Comprehensive Numerical Hydrodynamic Analysis of Submarine in a Straight Course Simulation Using Wall-Resolved RANS Models
This research explores several critical factors affecting CFD-based prediction accuracy of submarine hydrodynamics and builds upon previous work on preliminary mesh and solver benchmarking. A scaled submarine model is analyzed numerically using the Reynolds-Averaged Navier-Stokes (RANS) turbulence model at a Reynold number (Re) of 3.6x106 with wall-resolved meshes targeting y+ <5. Based on prior work using a 13x106 cells mesh generated with SnappyHexMesh, a mesh convergence study was performed …
