  1. 26. FOCUSING OF UWB RADAR SIGNALS USING TIME REVERSAL

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : FAHEEM AHMAD; PRAMOD KAKKERLA; [2013]
    Keywords : Radar; Time; Reversal; UWB; Signal;

    Abstract : Focusing techniques and detection of targets is usually associated to defense and military use. However in recent past things have moved ahead. Now target detection using UWB radars is being done in many industries and corporations. Radarbolaget AB is one of them; one of their projects uses UWB radars to detect steel strips inside a furnace.

  3. 27. Predicting Momentum Returns

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Mattias Holmberg; Martin Stenlund; [2013]
    Keywords : Dynamic; Momentum; Predictability; Reversal; Trading strategy;

    Abstract : Momentum strategies have historically shown to yield positive returns with little systematic risk exposure. Although usually profitable over long time periods, momentum strategies have also shown to suffer from irregular but severe losses that effectively erode the strategies' attractiveness. READ MORE

  4. 28. Point defects in the (d+id)-wave superconducting state of heavily doped graphene

    University essay from Institutionen för fysik och astronomi

    Author : Tomas Löthman; [2013]
    Keywords : Graphene; Superconductivity; Defects; Van Hove singularity;

    Abstract : Previous studies have suggested that the material graphene might transition into an electron-electron interaction driven, unconventional, time-reversal-symmetry-breaking, (d+id)wave superconducting state upon either significant electron or hole doping, and, in particular, upon doping to the Van Hove singularity. As defects are likely to be introduced in the doping process, we are, in this text, concerned with the effects of defects on this superconducting state near the Van Hove singularity doping.

  6. 30. Wastewater Treatment and Reuse through Constructed Wetlands Restoration of EU-Facultative Lagoons in Vientiane, Lao PDR

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Hui Su; [2012]
    Keywords : Earth and Environmental Sciences;

    Abstract : The massive infrastructure investments of the last 10 years in Vientiane (capital of Lao PDR) saw the city’s drainage network and wetlands being replaced by hydraulically more efficient cement-lined channels designed to ensure flood protection. As a result, water quality entering the receiving That Luang wetland has significantly degraded. READ MORE
