  1. 16. Lower hybrid drift wave properties in space

    University essay from Institutet för rymdfysik, Uppsalaavdelningen

    Author : Cecilia Norgren; [2011]
    Keywords : Lower hybrid drift waves; Lower hybrid drift instability; Cluster; Magnetotail; Plasma;

    Abstract : The whole universe is filled with plasma. There are different kinds of plasmas filling large volumes, separated by distinct boundaries. Many important energy conversion, particle acceleration and plasma transport processes occur at these boundaries, and therefore it is important to study the plasma processes there. READ MORE

  3. 17. Spin-dependent Recombination in GaNAs

    University essay from Institutionen för fysik, kemi och biologi; Funktionella elektroniska material

    Author : Yuttapoom Puttisong; [2009]
    Keywords : GaNAs; spin filter; spin dependent recpmbination; defect;

    Abstract : Spin filtering properties of novel GaNAs alloys are reported in this thesis. Spin-dependent recombination (SDR) in GaNAs via a deep paramagnetic defect center is intensively studied. READ MORE

  4. 18. An investigation of friction graphs ranking ability regarding the galling phenomenon in dry SOFS contact : (Adhesive material transfere and friction)

    University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

    Author : Harald Wallin; [2008]
    Keywords : galling; friction; adhesive contact; mild adhesive; severe adhesive; abrasive; flattening; SOFS; TNO; slider on flat surface; tribology; dry; lubricated; frictional heating; acceleration; plastic zone; contact pressure; pressure; phase transformation; morphology; seizure; scoring; scuffing; cohesive forces; classification; characteristic patterns; lump; sheet damage; på kletning; friction; kontakt tryck; värme; plogning;

    Abstract : The main purpose of this project is to investigate different tool steels in terms of their ability to withstand material transfer buildup, so-called galling, occurring in SMF (sheet metal forming) operations. The ability to withstand galling is vital to optimize cost-effectiveness and increase the work tool’s effective operational time. READ MORE

  5. 19. Electrostatic Forces for Swarm Navigation and Reconfiguration

    University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Author : Muhammad Kamran Saleem; [2007]
    Keywords : Spacecraft Formation Flying; Coulomb Satellites; Hybrid Propulstion System;

    Abstract : In this study, we have developed a navigation scheme for a swarm of satellites equipped with both electrostatic and conventional actuators. The main features of two new concepts for formation flying control i.e. READ MORE
