  1. 1. Ion Temperature Anisotropies in the Venus Plasma Environment

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Alexander Bader; [2017]
    Keywords : Venus; magnetospheric physics; plasma wave; ion distribution; anisotropy; temperature;

    Abstract : Velocity distributions are a key to understanding the interplay between particles and waves in a plasma. Any deviation from a Maxwellian distribution may be unstable and result in wave generation. READ MORE

  2. 2. Measurement and Simulation of Cable Impedance Parameters in 600 V System

    University essay from Chalmers tekniska högskola/Institutionen för elektroteknik

    Author : Afraah Fathima Burhanuddin; Haresh Viswanathan; [2017]
    Keywords : Finite Element Method FEM ; Vector Network Analyzer VNA ; Coaxial; Twinaxial; Grounding; Shield; Coupling;

    Abstract : This thesis presents measurement and simulation technique of cable impedance parametersin 600 V system. Coaxial and twinaxial cables are the two types of cablesanalyzed. The cables are modelled in finite element method (FEM) software usingthe concept of transverse electric magnetic (TEM) waves. READ MORE

  3. 3. A statistical investigation of Bursty Bulk Flow event dynamics in the Earth magnetotail

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Thomas Zhang; [2014]
    Keywords : Bursty Bulk Flow; Cluster; Curlometer method; Lorentz force;

    Abstract : A statistical investigation of the relationship between Lorentz force and Bursty Bulk Flow event (BBF) spatial location in the magnetotail is undertaken. Data is obtained in situ by the ESA Cluster II mission during the period July to October 2004. Firstly, a short introduction to BBFs and the Cluster mission is presented. READ MORE

  4. 4. Design of a Vector Network AnalyzerFerroMagnetic Resonance set upand measurements on multilayerHeusler samples

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Johan Eriksson; [2010]
    Keywords : Ferrromagnetic Resonance; Heusler; Magnetic Susceptibility;

    Abstract : The resonance frequency and the damping constant are interesting parametersrelated to the ferromagnetic spin resonance phenomenon. In this study theseparameters have been investigated for a number of Heusler multilayer film samplesusing a vector network analyzer ferromagnetic resonance setup. READ MORE

  5. 5. MR scanner independent 3D B1 field mapping of magnetic resonance spectroscopy RF coils using an automated measurement system

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Vaclav Brandejsky; [2008]
    Keywords : spectroscopy;

    Abstract : We developed a method for measurement of the B1+/- fields as an alternative approach to B1+/- fields assessment in MR scanner. Our setup incorporates an industrial coordinate table controlled by a PC-based program, search coils, a two--port vector network analyzer and an analog-to-digital (A/D) card. READ MORE
