1. 21. Field Current Control for the Damping of Rotor Oscillations and for the Alternative Start of Synchronous Machines : Further Innovative Applications of Field Current Active Control besides UMP-Compensation

   Master-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

   Författare :Roberto Felicetti; [2018]
   Nyckelord :asynchronous start; current control; damping bars; damper winding; d-axis; q-axis; hunting; natural frequency; Park s reference frame; rotor back-EMF; rotor oscillations; synchronous motor;

   Sammanfattning : The possibility to save energy in synchronous machines operation by dismissing d-axis damping bars and surrogating them with active excitation current control in sectored field winding is proved. In particular a way to recover the energy of rotor oscillations during power regulation is shown by means of a studycase generator whereas a self-starting machine is analytically and numerically designed in view of its next construction and test.

4. 23. Preliminary analysis of the potential energy saving achievable with a predictive control strategy of a heat pump for a single family house

   Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

   Författare :Giacomo Braida; Roberto Tomasetig; [2018]
   Nyckelord :heat pump system control; HVAC predictive rule-based control; weather forecast; occupancy behavior; internal gain; ambient temperature; perfect prediction;

   Sammanfattning : The present work reports a study related to the potential improvement of the energy performances of a heat pump based heating system for a Swedish single-family house. The analysis is focused on the design of new rule-based control strategies which employ perfect predictions of weather forecast and human behaviour information. LÄS MER

5. 24. Are you there? In search of a quality engagement on internet between international development organizations and their social media audience through dialogue and active participation

   Magister-uppsats, Malmö universitet/Fakulteten för kultur och samhälle (KS)

   Författare :Roberto Carrera Hernández; [2018]
   Nyckelord :engagement; dialogue; active participation; interaction; social media; clicktivism; development; communication; international development organizations; UNESCO;

   Sammanfattning : Social media have become one of the most important tools for international development organizations when it comes to spreading their message and reach a greater number of followers around the world. However, the connection between the users and the organization is mainly based on one-click basic interactions which does not guarantee a strong commitment. LÄS MER

7. 25. On the Translation of Adjectival Pre-Modifiers : A Study of English-Swedish Translation Shifts
