1. 1. Sensorless method of detecting plunger position in solenoid actuators

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Simon Hed; Axel Knutsson; [2020]
   Nyckelord :Technology and Engineering;

   Sammanfattning : This thesis investigates if it is possible to measure the plunger position in a Ledex 282352-023 solenoid actuator without the use of external sensors. To do this, various different methods, all based on comparing the current response to the applied voltage were evaluated from different categories such as calculation time, reliability and distinct position levels.

3. 2. En strukturgeologisk modell för berggrunden i Sarvesvagge-Luottolako-området, Sareks Nationalpark, Lappland

   Magister-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Mats G. Lund; [1999]
   Nyckelord :Caledonides; overthrusting; duplex; tectonostratigraphy; structural geology; Sarek; Earth and Environmental Sciences;

   Sammanfattning : The high plateau of Luottolako constitutes a topographical area strongly contrasting from the rugged Sarek Mountains. Older geological maps show that not only the topography, but also the bedrock is different compared to the surrounding massifs. However, the boundaries in the previously publis-hed maps indicate impossible structural models. LÄS MER
