Design and Implementation of a Controlled Ransomware Framework for Educational Purposes Using Flutter Cryptographic APIs on Desktop PCs and Android Devices
This study focuses on the creation and implementation of ransomware for educational purposes that leverages Python's native cryptographic APIs in a controlled environment. Additionally, an Android version of the framework is implemented using Flutter and Dart. For both versions, open-source cryptographic libraries are utilized. With this framework, researchers can systematically explore the functionalities of ransomware, including file encryption processes, cryptographic key management, and vic…

Exploring near critical lattice gauge simulators with Rydberg atoms facilities
We motivate the use of a ladder of Rydberg atoms as an analog simulator for a lattice gauge theory version of scalar electrodynamics also called the compact Abelian Higgs model. We demonstrate that by using a few thousand shots from a single copy of the ladder simulator it is possible to estimate the bipartite quantum von Neumann entanglement entropy $S^{vN}_A$. The estimation relies on an optimized filtration of the mutual information associated with the bitstrings obtained from public facilit…

Complexity of some modal logics of density (extended version)
By using a selective filtration argument, we prove that the satisfiability problem of the unimodal logic of density is in $EXPTIME$. By using a tableau-like approach, we prove that the satisfiability problem of the bimodal logic of weak density is in $PSPACE$.

EMORF-II: Adaptive EM-based Outlier-Robust Filtering with Correlated Measurement Noise
We present a learning-based outlier-robust filter for a general setup where the measurement noise can be correlated. Since it is an enhanced version of EM-based outlier robust filter (EMORF), we call it as EMORF-II. As it is equipped with an additional powerful feature to learn the outlier characteristics during inference along with outlier-detection, EMORF-II has improved outlier-mitigation capability. Numerical experiments confirm performance gains as compared to the state-of-the-art methods …

The Difference between the Left and Right Invariant Extended Kalman Filter
The extended Kalman filter (EKF) has been the industry standard for state estimation problems over the past sixty years. The Invariant Extended Kalman Filter (IEKF) is a recent development of the EKF for the class of group-affine systems on Lie groups that has shown superior performance for inertial navigation problems. The IEKF comes in two versions, left- and right- handed respectively, and there is a perception in the robotics community that these filters are different and one should choose …

Ich bin ja ohnehin kein großer #SharePoint-Freund, aber es gibt eine Sache, die mich mit Abstand am meisten nervt: Die Zeit, die vergehen kann, bevor eine Einstellung auch wirklich in der Oberfläche wirksam wird.
Ich hab das Label für einen Filter angepasst und warte jetzt seit ~15 Minuten, dass das jetzt auch entsprechend angezeigt wird...

Frequency Domain Design of a Reset-Based Filter: An Add-On Nonlinear Filter for Industrial Motion Control
This study introduces a modified version of the Constant-in-Gain, Lead-in-Phase (CgLp) filter, which incorporates a feedthrough term in the First-Order Reset Element (FORE) to reduce the undesirable nonlinearities and achieve an almost constant gain across all frequencies. A backward calculation approach is proposed to derive the additional parameter introduced by the feedthrough term, enabling designers to easily tune the filter to generate the required phase. The paper also presents an add-on…

A New Method of Deriving Doppler Velocities for Solar Orbiter SPICE
This paper presents a follow-up to previous work on correcting PSF-induced Doppler artifacts in observations by the SPICE spectrograph on Solar Orbiter. In a previous paper, we demonstrated correction of these artifacts in the $y-λ$ plane with PSF Regularization, treating the forward problem with a method based on large sparse matrix inversion. It has since been found that similar apparent artifacts are also present in the $x-λ$ direction, i.e., across adjacent slit positions. This is difficu…

Reflection-less filter for superconducting quantum circuits
Protecting superconducting quantum circuits from non-ideal return loss, including out-of-band circulator behavior and enhancing the performance of broadband quantum-limited amplifiers can be accomplished using a superconducting version of a special class of microwave filters known as reflection-less filters. These filters can simultaneously permit low pass band loss to preserve quantum efficiency and broad band reflection-less characteristics in the stop and pass bands. The filter also suppress…
