This paper proposes a motion control scheme for robots operating in a dynamic environment with concave obstacles. A Model Predictive Controller (MPC) is constructed to drive the robot towards a goal position while ensuring collision avoidance without direct use of obstacle information in the optimization problem. This is achieved by guaranteeing tracking performance of an appropriately designed re

Cross-sections for the production of a Z boson in association with two photons are measured in proton–proton collisions at a centre-of-mass energy of 13 TeV. The data used correspond to an integrated luminosity of 139 fb - 1 recorded by the ATLAS experiment during Run 2 of the LHC. The measurements use the electron and muon decay channels of the Z boson, and a fiducial phase-space region where the

Results of a measurement of dimuon photoproduction in nonultraperipheral Pb + Pb collisions at √sNN = 5.02 TeV are presented. Themeasurement uses ATLAS data from the 2015 and 2018 Pb + Pb data-taking periods at the LHC with an integrated luminosity of 1.94 nb.1. The γγ → μ+ μ- pairs are identified via selections on pair momentum asymmetry and acoplanarity. Differential cross sections for dimuon pr

This paper presents direct searches for lepton flavour violation in Higgs boson decays, H → eτ and H → μτ, performed using data collected with the ATLAS detector at the LHC. The searches are based on a data sample of proton-proton collisions at a centre-of-mass energy s = 13 TeV, corresponding to an integrated luminosity of 138 fb −1. Leptonic (τ → ℓνℓ ντ) and hadronic (τ → hadrons ντ) decays of t

In this paper, we introduce OT-PCA, a novel approach for conducting Plaintext-Checking (PC) oracle based side-channel attacks, specifically designed for Hamming Quasi-Cyclic (HQC). By calling the publicly accessible HQC decoder, we build offline templates that enable efficient extraction of soft information for hundreds of secret positions with just a single PC oracle call. Our method addresses cr

Psykologiforskare och psykologin som disciplin påverkar i stor utsträckning hur människor förstår sig själva och världen. Därför behöver de som använder sig av psykologi inom sitt yrke reflektera över vilken kunskap och vilka normer som de skapar och reproducerar. Som tidigare nämnts har psykologin en historia av att exkludera, sjukdomsförklara och omöjliggöra de levnadssätt som inte ingått i norm

Vem styr det civila samhället i Sverige? Denna viktiga gemensamma del av samhället, skild från staten och marknaden, framställs ofta som en motvikt till den maktordning som gäller i politik och näringsliv. I rörelser som idrottsföreningar, intressegrupper och trossamfund kan strukturerna tyckas mer tillåtande och inkluderande. Men vad vet vi egentligen om det civila samhällets interna hierarkiska

How is practical change work carried out in modern organizations? And what kind of challenges, tasks and other difficulties are normally encountered? In a turbulent and changing world, organizational culture is often seen as central for sustained competitiveness. Organizations are faced with increased demands for change but these are often so challenging that they meet heavy resistance and fizzle
