  1. 1. Embedded Element Patterns in Combination with Circuit Simulations for Multi-Port Antenna Analysis

    Författare :Kristian Karlsson; Högskolan i Jönköping.; RISE.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antenna efficiency; Greens function; multi-port antenna; impedance matching; reverberation chamber; correlation; antenna arrays; Embedded element pattern; optimization; antenna diversity;

    Sammanfattning : This thesis is a result from work on two different subjects, electromagnetic simulations of reverberation chambers and a methodology for the analysis of multi-port antennas. The subjects can be linked together by their contribution to knowledge in electromagnetic simulations and characterization of antennas. LÄS MER

  2. 2. Safe Transitions to Manual Driving From Faulty Automated Driving System

    Författare :Josef Nilsson; RISE.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver takeover; functional safety; automated driving; safety; vehicle automation; driver capability; brake failure; controllability; driving simulator.;

    Sammanfattning : This thesis presents a method to assess the safety of transitions from automated to manual driving when vehicle automation fails. The method is based on contributions to the understanding of human driving behavior, also presented in this thesis. LÄS MER

  3. 3. Frequency Transfer Techniques and Applications in Fiber Optic Communication Systems

    Författare :Sven-Christian Ebenhag; RISE.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronous digital hierarchy SDH ; UTC; synchronization; Time transfer; optical fiber; optical fiber network; GPS carrier phase; global positioning system GPS ; synchronous optical networking SONET ;

    Sammanfattning : Modern society is dependent on communications and the developments of these increases constantly through a seemingly endless demand for communication services and thereby synchronization and time. This is confirmed by a vast range of research on communications, irrespective of technology and protocol. LÄS MER

  5. 5. Assessment of safety characteristics for Li-ion battery cells by abuse testing

    Detta är en avhandling från Linköping University Electronic Press

    Författare :Fredrik Larsson; Carl Fredrik Larsson; SP Elektronik.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; overcharge; Lithium-ion; toxic gases; abuse test; thermal runaway; short circuit; safety; battery; fire;

    Sammanfattning : Despite the many advantages with lithium-ion batteries there can be disadvantages in form of safetyissues. In an abuse situation a Li-ion cell can undergo a thermal runaway releasing excessive heat,flammable and toxic gas emissions and eventually accompanied by dissembling/explosion and fire. LÄS MER
