  1. 16. Information Flow and Local Observables in Many Body Localized Systems

    University essay from KTH/Fysik

    Author : Daniel Niemi; [2022]
    Keywords : Theoretical physics; many body localization; localization; aubry-andré; aubry-andrei; condensed matter; quantum matter; Teroretisk fysik; mångpartikellokalisering; lokalisering; aubry-andré; aubry-andrei; kondenserad materia; kvantmateria;

    Abstract : Disordered quantum many-body systems exhibiting the many-body localization (MBL) phenomenon evade the fate of thermalization due to the existence of an extensively large set of quasi-local integrals of motion (l-bits). Due to the size of the Hilbert space of many-body systems, it is hard to compute the time evolution of many-body systems generally, which hinders our understanding of the MBL phenomenon. READ MORE

  3. 17. Distance Estimation of Two Distance Sensors

    University essay from Blekinge Tekniska Högskola

    Author : Kamuju Vamsi Bhargav; Yenuga Aditya Pavan Kumar; [2022]
    Keywords : Short-range sensor; long-range sensor; Arduino UNO microcontroller;

    Abstract : In modern world sensors play important role where they help to acquire information about the procecess, such as temperature, velocity,distance, etc. Based on this information acquired from the sensorsdecisions can be made, for example to increase heating in the buildingor accelerate the car.

  4. 18. Modelling Magnetism of hcp Iron under Earth’s Inner Core Conditions : Based on first-principle DFT calculations and Machine Learning

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Linda Le; [2022]
    Keywords : Machine learning; Earth’s Inner Core; hcp Iron; Electronic structure magnetism; Density functional Theory; Local magnetic moments; Ab initio molecular dynamics; ASD-AIMD-MLLSF simulation;

    Abstract : The structure of Earth’s core remains largely a mystery. The solid inner core is believed to exist in extreme pressure and temperature conditions comparable to 300 GPa and 6000 K and consists mainly of iron, Fe. READ MORE

  5. 19. Multiscale numerical approximation of morphology formation in ternary mixtures with evaporation : Discrete and continuum models for high-performance computing

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Mario Setta; [2021]
    Keywords : ;

    Abstract : We propose three models to study morphology formations in interacting ternary mixtures with the evaporation of one component. Our models involve three distinct length scales: microscopic, mesoscopic, and respectively, macroscopic. READ MORE

  6. 20. Multipath Modelling for 60 GHz Short Range Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Andre Nüsslein; [2021]
    Keywords : Radar; Surveillance; Multipath; Mathematics and Statistics;

    Abstract : If radar surveillance systems are installed near a wall, their radiation is reflected not only from moving objects but also from the wall. In this way, non­existing so­called ghost targets can lead to false detections. This thesis exploits such ghost detections to infer the position and extension of a wall next to a radar sensor.
