Sensitivity measures how much the output of an algorithm changes, in terms of Hamming distance, when part of the input is modified. While approximation algorithms with low sensitivity have been developed for many problems, no sensitivity lower bounds were previously known for approximation algorithms. In this work, we establish the first polynomial lower bound on the sensitivity of (randomized) ap
This paper presents a lightweight architecture for AI-driven tutoring in extended reality (XR) environments, integrating OpenAI's GPT-4o real-time API directly into Unitybased virtual reality (VR) to enable seamless voice-native interaction without external speech modules. Designed for taskbased learning, the tutor provides immediate, context-sensitive verbal feedback with adaptive brevity and low
As the Hamming Quasi-Cyclic (HQC) cryptosystem was recently selected by NIST for standardization, a thorough evaluation of its implementation security is critical before its widespread deployment. This paper presents single-trace side-channel attacks that recover the full long-term secret key of HQC, experimentally evaluated on a protected Cortex-M4 implementation. We introduce two distinct attack
Regogörelse för när Lunds universitet 1844 erbjöds egendomen Häckeberga som donation, men på villkor som gjorde att regeringen beslöt att avböja gåvan.
Reconfigurable scan networks (RSNs) provide efficient and flexible access to on-chip logic, such as instruments for test and diagnostics, throughout a semiconductor’s lifetime. Test instruments are powerful, as they provide high controllability and observability. The availability of a high number of test instruments, as well as the standardized and easy access, makes RSNs a valuable target for an
The focus of this study is threefold: (1) to examine how jaw displacement patterns vary with prosodic focus in American English, (2) to determine whether narrow focus induces greater jaw lowering than broad focus, and (3) to compare two different techniques for recording these jaw displacement patterns—Electromagnetic Articulography (EMA) and the new, innovative MARRYS helmet system. Simultaneous
This study presents high-fidelity Large Eddy Simulations (LES) of supersonic combustion in a Mach 2 cavity flameholder over the full stable fueling region from 40 to 200 slpm. The simulations employ Finite Rate Chemistry LES with the Z70 ethylene-air mechanism, the Localized Dynamic k-equation model, Partially Stirred Reactor turbulence-chemistry interaction model, conjugate heat transfer, and the
Due to the threat climate change poses, the aviation industry needs to adapt. In the process to convert the aviation fleet into a more environmentally friendly fleet, using biofuels such as Sustainable Aviation Fuels as a drop-in fuel remains a promising option. To include biofuels, safety aspects need to be investigated, where combustion instabilities are important. Thermo-acoustic instabilities
In this study we compared the latencies and amplitudes of pupillary light responses, recorded by a Tobii Pro Spark eye-tracker and a setup combining PupilEXT, a free open-source software for pupillometry, with an industrial camera. Pupil size was recorded simultaneously with both systems while illumination was provided by the Spark. Results show that neither pupillary response latencies nor amplit
Here we present the integrated design, high-fidelity simulation, and virtual emissioncertification of a medium-range aero-engine combustor developed within the EU-funded MYTHOS project. The objective is to establish a physics-based framework capable of predicting combustor behavior for both conventional fuels and emerging Sustainable Aviation Fuels (SAF). Starting from a 0D thermodynamic cycle, a
We present PyeLink and SyeLink, two complementary open-source Python tools for running eye-tracking experiments and parsing data from SR Research Ltd. EyeLink eye tracking hardware. PyeLink simplifies experiment creation through plug-and-play support for multiple display backends (Pygame, PsychoPy, Pyglet) while enabling two features not available in existing tools: recording data during calibrati
Historical sources written in rare or undeciphered scripts represent an immense but underexploited part of the world’s cultural and linguistic heritage. Their study is often hindered by fragmentary preservation, non-standard symbol systems, and the absence of interoperable digital resources. While recent advances in imaging, transcription, and computational analysis have improved access to histori
