1. Introducing disturbances to a chopped PIR sensor when investigating the performance in an office environment
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This master's thesis, conducted in collaboration with Knowit Connectivity, aims to develop a booking device for meeting rooms. The focus of the project is to identify and mitigate disturbances in the C-PIR sensor introduced by Haili Liu et al. LÄS MER
2. Smart Bird Feeder : Self-propelled and interactive
Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Bird feeding is somthing most are familiar with, either when children are feeding the swans or adults using some type of bird feeder in the garden. This project took that as inspiration to create something that automatically feed the birds while also monitoring them by capturing a picture and sending out this information as a teet on Twitter.

3. Microwave Radar Implementation in Outdoor Home Alarm Systems
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : The use of short range microwave radars for motion sensing purposes are on the rise in multiple industries, as they are accurate, small in size and relatively cheap. The automotive industry, in particular, has pushed the development forward. Lately, the home alarm industry has also been glancing at the technology. LÄS MER
4. Komparativ studie av rörelsedetektorer i ett övervakningssystem
M1-uppsats, Jönköping University/JTH, Datateknik och informatikSammanfattning : 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.

5. 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 StudiesSammanfattning : 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.
