  1. 1. Investigations of the Transient Luminous Events with the small satellites, balloons and ground-based instruments

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Safura Mirzayeva; [2022]
    Nyckelord :TLE; sprite; jet; elve; halo; lightning; lighting detection; upper-atmospheric lightning; lightning location; nanosatellite; CubeSat;

    Sammanfattning : The lightning is the natural source of electromagnetic radiation. It is an atmospheric electrical discharge.  However, since recent times, it was discovered that there are other types of lightning besides those that are visible to the naked eye. They are called TLEs (Transient Luminous Event) and take place above the clouds during thunderstorms. LÄS MER

  3. 2. Utvärdering av Blitzortung blixtlokaliseringssystem : En jämförande studie med SMHI som referenssystem

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Adam Bergman; [2017]
    Nyckelord :blixtlokalisering; blixtdetektering; elnät; energi; blixtar; Blitzortung; SMHI;

    Sammanfattning : Blitzortung is a non-commercial lightning detection system intended for recreational use only. In this thesis the performance of the Blitzortung system is evaluated in order to see to which extent it can be compared to a high performance commercial lightning detection system for use in Sweden.

  4. 3. Analys av NIR hårdvaruuppsättning samt metod för fotografering av individer i fordon

    Kandidat-uppsats, Högskolan i Jönköping/JTH, Data- och elektroteknik

    Författare :Bäckman Eddie; Jacob Stjerneklev; [2016]
    Nyckelord :NIR; IR; HOV; bildanalys; trafikövervakning;

    Sammanfattning : Abstract Purpose – To study the possibility of using a NIR hardware solution to photograph individuals in a private vehicle as well as an analysis of its images. Method – A study of existing theories around the NIR-method’s performance in selected conditions and individual tests were performed to examine if the literature statements were valid for this study.

  5. 4. Energieffektivisering av Exaktas elförbrukning

    Kandidat-uppsats, Lunds universitet/Högskoleingenjörsutbildning i datateknik

    Författare :Alexander Andinger; [2016]
    Nyckelord :frekvensomriktare; energibesparing; led lysrör; rörelsedetektorer; varvtalsreglering; Technology and Engineering;

    Sammanfattning : This thesis was completed at Exakta Printing in Malmo. The purpose of this work was to identify different elements that consume energy, such as lightning, machinery, compressed air, ventilation, etc., in order to present several suggestions on how to reduce the energy consumption and the costs within the chosen area.

  7. 5. Utveckling av webbaserat blixtdetekteringssystem

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Anhar Al Sayfi; Max Kufa; [2016]
    Nyckelord :Sensor; AS3935; Lightning detection; TOA; Algortihm; MDF; Php; Apache; LAMP; Rasperry pi; server; Pushbullet.; Sensor; AS3935; Blixtdetektering; TOA; Algoritm; MDF; Php; Apache; LAMP; Rasperry pi; server; Pushbullet.;

    Sammanfattning : In this paper we suggest a lightning detection system capable of warning a local populous of incoming lightning weather using a combination of the AS3935 sensor and the one-board-computer Raspberry Pi, in an attempt to design a product that is cheap, mobile and easy to use. The product is composed of a sensor net that registers and reports lightnings on a webserver. LÄS MER
