  1. 1. Mass-Singularity Structure of QED and Perturbative Quantum Gravity Scatterings

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Santiago Londono Castillo; [2020]
    Keywords : perturbative quantum gravity; QED; mass singularities; collinear singularities; soft singularities; singularity cancellation; graviton; Physics and Astronomy;

    Abstract : In this thesis, the mass singularities occurring in the cross-section of electron scattering processes are investigated. Two types of scatterings are studied: Quantum Electrodynamics (QED) scatterings, and Perturbative Quantum Gravity (PQG) scatterings. READ MORE

  2. 2. Principles of an automatic brewing machine : By using CodeSys with Raspberry Pi

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Daniel Mårtensson; [2017]
    Keywords : Brewing; Beer; Automatic; PLC; Control; Bryggning; Öl; Automation; PLC; Kontrol;

    Abstract : This project will give you a view from another side when it comes to control engineering and mechanical construction in brewing. This is a thesis project about principles for an automatic brewing machine. This project started off with prestudy of earlier research results in automatic brewing based on the Arduino platform.

  3. 3. Low–voltage External Discharge Plasma Thruster and Hollow Cathodes Plasma Plume Diagnostics Utilising Electrostatic Probes and Retarding Potential Analyser

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : George-Cristian Potrivitu; [2016]
    Keywords : space electric propulsion; in-space advanced propulsion technology; Hall effect thruster; hollow cathode; wall-less Hall thruster; external discharge plasma thruster; single Langmuir probe; double Langmuir probe; emissive probe; retarding potential analyzer; plume plasma diagnostics; low-voltage Hall thruster; high-current hollow cathode; plasma parameters; propulsion electrique pour l espace; cathode creuse à fort courant; propulseur à décharge externe de plasma; propulseur à effet Hall à basse tension; techniques de diagnostic du plasma; sonde de Langmuir simple; sonde de Langmuir double; sonde émissive; analyseur à potentiel retardé;

    Abstract : The present thesis is the result of a research period at the Institute of Space and Astronautical Science of the Japanese Aerospace Exploration Agency, ISAS/JAXA within Funaki Laboratory of the Department of Space Flight Systems that followed the path of plume plasma diagnostics for space electric propulsion drives. During the experimental studies two high-current hollow cathodes and an innovative prototype of a low-voltage fully external discharge plasma thruster (XPT) had their plasma plumes diagnosed using electrostatic probes and retarding potential analyser (RPA).

  4. 4. The kaon electromagnetic mass difference in AdS/QCD

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Jack Borthwick; [2016]
    Keywords : particle physics; AdS QCD; AdS CFT; kaon; electromagnetic mass difference; quantum field theory; Physics and Astronomy;

    Abstract : In this thesis, a holographic model for quantum chromodynamics (QCD) is used to estimate the electromagnetic contribution to the kaon mass difference. The principal ideas of the model are inspired by the AdS/CFT correspondence, which is believed to be exact. READ MORE

  5. 5. Calibration of fundamental diagrams for travel time predictions based on the cell transmission model

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : Christoph Seybold; [2015]
    Keywords : Cell transmission model CTM ; Fundamental diagrams; Calibration; Dynamic sources; Dynamic sinks; Split ratios;

    Abstract : Road traffic increases constantly and the negative consequences in the form of traffic jams can be realized especially in urban areas. In order to provide real time traffic information to road users and traffic managers, accurate computer models gain relevance. READ MORE
