  1. 1. An FPGA Based MPPT and Monitoring System : suitable for a photovoltaic based microgrid

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Rongpeng Zheng; [2019]
    Nyckelord :Microgrids; Monitoring System; Maximum Power Point Tracking MPPT ; Stand-alone Mode; Grid-connected Mode; FPGA; Verilog HDL.;

    Sammanfattning : Microgrids containing photovoltaic (PV) cells and wind power gain more and more interest. These microgrids may work in stand-alone mode ("islanding") or be conncted to the main grid. In both modes of operation, power quality must be monitored and controlled. This report focuses on microgrids and aims to implement a monitoring system based on FPGA. LÄS MER

  3. 2. University of Cyprus Library students’ perceptions of information literacy

    Master-uppsats, Högskolan i Borås/Akademin för bibliotek, information, pedagogik och IT

    Författare :Lilia Charalambous; [2018]
    Nyckelord :Information literacy; information skills; academic libraries; university students; Republic of Cyprus; University of Cyprus; library instruction;

    Sammanfattning : The purpose of this qualitative study is to contribute knowledge on how students in an academic setting conceptualise information literacy, how they interact with information and library provided resources to meet their information needs, as well as to examine how the academic library supports students with their studies as a facilitator and its role in information literacy instruction. Taking a qualitative approach, the study used semi-structured interviews to gather the necessary data. LÄS MER

  4. 3. Live updates in High-availability (HA) clouds

    Master-uppsats,

    Författare :Vivek Sanagari; [2018]
    Nyckelord :Cloud; Cluster; Corosync; Distributed Replicated Block Device; High Availability; Pacemaker; Virtual machine; Web server; Web Application.;

    Sammanfattning : Background. High-availability (HA) is a cloud’s ability to keep functioning after one or more hardware or software components fail. Its purpose is to minimize the system downtime and data loss. LÄS MER

  5. 4. Ett resecentrums betydelse för en stadskärna . : En studie om Kramfors resecentrums funktion och relation till den urbana omgivningen, samt upplevelsen av denna

    M1-uppsats, Umeå universitet/Kulturgeografi

    Författare :Martin Söderström; [2014]
    Nyckelord :;

    Sammanfattning : The purpose of this study is to shed light on and describe Kramfors travel centers function and relationship to the surrounding urban environment, and how this core is experienced by residents and visitors. To do this, the use of the travel center, its relationship to Kramfors city center and the perception of it, as well as possible improvement areas has been studied. LÄS MER

  7. 5. Assessment of the applicability of XFEM in Abaqus for modeling crack growth in rubber.

    Magister-uppsats, KTH/Hållfasthetslära (Inst.)

    Författare :Luigi Gigliotti; [2012]
    Nyckelord :Fracture Mechanics; eXtended Finite Element Method; Rubber-like materials; Abaqus;

    Sammanfattning : The eXtended Finite Element Method is a partition of unity based method, particularly suitable for modelling crack propagation phenomena, without knowing a priori the crack path. Its numerical implementation is mostly achieved with stand-alone codes. LÄS MER
