1. Localization of eNodeBs with a Large Set of Measurements from Train Routers
Master-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)Sammanfattning : This master thesis investigates the possibility of locating LTE base stations, known as eNodeBs, using signal measurements collected by routers on trains. Four existing algorithms for transmitter localization are adopted: the centroid, strongest signal, Monte Carlo path loss simulation and power difference of arrival (PDoA) methods. LÄS MER
2. Non-Coherent Radio-Based Positioning
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : In this thesis, a new Angle-of-Arrival (AoA) technique is used to determine the direction of a target in an outdoor environment using Radio Frequency (RF) signals. This technique estimates the AoA based on the difference between the Received Signal Strength Indicators (RSSI) from two/four directive antennas. LÄS MER
3. Indoor Positioning Using WLAN
Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : This report evaluates various methods that can be used to position a smartphone running the Android platform, without the use of any special hardware or infrastructure and in conditions where GPS is unavailable or unreliable; such as indoors. Furthermore, it covers the implementation of such a system with the use of a deterministic fingerprinting method that is reasonably device independent, a method which involves measuring a series of reference points, called fingerprints, in an area and using those to locate the user.

4. Potential of existing UMTS Signaling Data for Cell Phone Positioning
Master-uppsats, Institutionen för teknik och naturvetenskapSammanfattning : In the current era of telecommunication the usage of cellular network has increased rapidly. Number of different new services are introduced i.e. navigation, friend finder, internet browsing, nearby filling stations, shopping centers, traffic information and emergency services. LÄS MER
5. Pårørende til personer med demens : Evaluering av en psykoedukativ intervensjon rettet mot pårørende
Master-uppsats, Nordiska ministerrådet/Nordic School of Public Health NHVSammanfattning : Bakgrunn: ”Demens i familien” er en intervensjonsstudie hvor psykoedukativ metode ble benyttet for å redusere stress hos pårørende, og for å redusere psykiatriske tilleggssymptomer hos personer med demens. Studien pågikk i Norge fra 2001-2004. Denne MPH- oppgaven er en delstudie av”Demens i familien”. LÄS MER
