  1. 16. Komparativ studie av rörelsedetektorer i ett övervakningssystem

    M1-uppsats, Jönköping University/JTH, Datateknik och informatik

    Författare :Makail Ismail Ahmed; Antonio Sürer; [2020]
    Nyckelord :PIR;

    Sammanfattning : False alarms in home surveillance systems are an annoyance for customers and it has become a much-debated topic. There are several previous studies where the purpose is to reduce the number of false alarms in home surveillance systems, but not about combining different types of sensors in different sensitivities that complement each other.

  3. 17. Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :David Kymmell; [2019]
    Nyckelord :landscape of fear; forest fire effects; herbivore prey; camera trapping;

    Sammanfattning : Context: A major effect of climatic change is the global increase in forest fires, which potentially creates an increase in food availability for herbivorous species. Also vegetation density and the numbers of tree logs increase in burned sites, and this is thought to influence the perceived risk of herbivore prey species, which affects their anti‐predator behaviour and thereby the patch utilization.

  4. 18. IoT Based Home Monitoring System

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Författare :TABU SRAVANI GUDURU; SURYA NARAYANA MURTHY THATAVARTHY; [2019]
    Nyckelord :Arduino; Application; ESP32-CAM; PIR sensor; Web Interface;

    Sammanfattning :  Home surveillance is a major concern in this day and age as with the rapid increase in the technology around us. There is a need to get updated with new possibilities to make our lives better and easy. Some cases and situations exhibit the need for home monitoring. So, we set out to discover a solution to this problem of home monitoring. LÄS MER

  5. 19. Utvärdering av PIR-isolering med Konkalorimeter

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Gustav Hahlin; [2019]
    Nyckelord :PIR; cone calorimeter; ISO-5660; Technology and Engineering;

    Sammanfattning : In this study four different types of PIR materials have been tested to examine the possibility to use the cone calorimeter (ISO 5660) as a screening tool to evaluate the fire properties of the insulation. As such, manufacturers can be able to make a quick control of the insulation without having to spend resources on full scale testing. LÄS MER

  7. 20. Att transformera platsspecifikt : Lantmännens pir i Ystad industrihamn

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Hampus Sundén; [2019]
    Nyckelord :transformation; platsspecifik analys; hamnomvandling; processkompassen; landskapsarkitektur;

    Sammanfattning : Med bakgrund i en kritisk diskussion i hur hamnomvandlingsområden ofta går i en monoton och generisk utveckling ämnar denna studie att förstå hur Lantmännens pir i Ystads kommun kan transformeras. Syftet med detta arbete är att studera och kreativt undersöka Lantmännens pir utifrån teorier som behandlar platsens olika spatiala lager och innebörden av det platsspecifika begreppet. LÄS MER
