1. 1. Current Control and Modelling of an Inspiration Valve

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Astrid Lindstedt; [2021]
   Keywords : Current Servo; Cascade Control; Solenoid Model; Ventilator; Strömregulator; Kaskadreglering; Solenoid modell; Respirator;

   Abstract : An analog current servo of an intensive care ventilator is being developed at Getinge in Stockholm. The current servo is used to control the output gas flow of an inspiration valve to a patient’s lungs. The ventilator’s control system is in a cascade design of two closed-loops, of which the current servo is the controller for the inner loop. READ MORE

3. 2. Sensorless method of detecting plunger position in solenoid actuators

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Simon Hed; Axel Knutsson; [2020]
   Keywords : Technology and Engineering;

   Abstract : 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.

4. 3. MAC-E-Filter characterization for PTOLEMY : a relic neutrino direct detection experiment

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Carl-Fabian Strid; [2019]
   Keywords : particle physics; astroparticle physics; astrophysics; PTOLEMY; relic neutrinos; monte carlo simulation; mac-e-filter; sterile neutrinos; physics beyond the standard model;

   Abstract : The cosmic neutrino background (CNB) can be composed of both active and hypothetical sterileneutrinos. At approximately one second after big bang, neutrinos decoupled from radiationand matter at a temperature of approximately one MeV. READ MORE

5. 4. Evaluation of a digitial displacement pump in a load haul dump application

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Jayasurya Madhusudanan; [2019]
   Keywords : Digital displacement pump; mine loader; energy efficiency; backward simulation; forward simulation; pump losses;

   Abstract : Hydraulics has always been the first choice of actuation in off-road, construction and mining vehicles due to its power density, low cost, built in cooling and lubrication. However, the current state of our environment along with stricter regulations has brought light to newer technologies within hydraulics to improve the existing system. READ MORE

6. 5. New Principle for Fluid Flow Measurement

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Markus Karlström; Fredrik Olsson; [2018]
   Keywords : flow measurement; rotameter; solenoid; magnet; drag; Technology and Engineering;

   Abstract : Fluid flow measurement is a task for which many different solutions exist. For high precision sensors the production cost is high and measurement principle is generally based on advanced theory. In this thesis a new principle of fluid flow measurement, based on the concept of a conventional rotameter, is investigated. READ MORE
