1. A study of methods to synchronize different sensors between two smartphones
M1-uppsats, KTH/Hälsoinformatik och logistikSammanfattning : Obtaining data simultaneously from different sensors located on different mobile devices can be useful for applications such as sports and medicine. In order for the data from the different sensors to be combined for analysis, the mobile devices need to be time synchronized first. LÄS MER
2. Hantering av mät-filer från Wi-Fi fjärrkontroll
Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : A measuring system Striton has been developed at the department of biomedicalengineering, University Hospital of Umeå, for motion analysis using motion sensors whichattaches to the patient’s lower body to assess the risk for potential neurological andmusculoskeletal damage. The measuring system is comprised of two motion sensor unitsand a remote control where data is gathered based on step height, step width, theorientation of the calves and step frequency. LÄS MER
3. Lokalisering av sensorer med LoRaWAN på Kalmar Länssjukhus
Kandidat-uppsats, KTH/Medicinteknik och hälsosystemSammanfattning : På Kalmar Länssjukhus har det varit problematiskt att lokalisera rullstolar på sjukhusets område. För att underlätta den dagliga verksamheten kring dessa rullstolar har sensorer uppkopplade till LoRaWAN varit en möjlig lösning. LÄS MER
4. Smartphone Based Indoor Positioning Using Wi-Fi Round Trip Time and IMU Sensors
Master-uppsats, Linköpings universitet/Institutionen för datavetenskapSammanfattning : While GPS long has been an industry standard for localization of an entity or person anywhere in the world, it loses much of its accuracy and value when used indoors. To enable services such as indoor navigation, other methods must be used. A new standard of the Wi-Fi protocol, IEEE 802. LÄS MER
5. Classification of Wi-Fi Sensor Data for a Smarter City : Probabilistic Classification using Bayesian Statistics
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistikSammanfattning : As cities are growing with an increasing number of residents, problems with the traffic such as congestion and larger emission arise. The city planners have challenges with making it as easy as possible for the residents to commute and in as large scale as possible to avoid vehicles. LÄS MER
