  1. 1. Ablation Programming for Machine Learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Sina Sheikholeslami; [2019]
    Nyckelord :Distributed Machine Learning; Distributed Systems; Ablation Studies; Apache Spark; Keras; Hopsworks;

    Sammanfattning : As machine learning systems are being used in an increasing number of applications from analysis of satellite sensory data and health-care analytics to smart virtual assistants and self-driving cars they are also becoming more and more complex. This means that more time and computing resources are needed in order to train the models and the number of design choices and hyperparameters will increase as well. LÄS MER

  3. 2. 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. 3. Establishing a suitable middleware based on reconstruction and repeating patterns

    Kandidat-uppsats, Malmö högskola/Fakulteten för teknik och samhälle (TS)

    Författare :Peter Johansson; Jesper Hansen; [2016]
    Nyckelord :Distributed systems; Middleware; XFS; Inter-process communication; JSON; Pipes; Reconstruction; UML; Patterns;

    Sammanfattning : I distribuerade system, kommunicerar komponenter genom att skicka meddelanden till varan- dra och mellanprogramvara överlappar integrationen mellan olika applikationer. Syftet var att undersöka och analysera olika designmönster till en mellanprogramvara som hanterar kommunikationen i en en-till-många relation och som kan användas i en XFS baserad programvara samt identifiera eventuella problem som uppkom under utvecklingsprocessen.

  5. 4. Kvalitetsförbättringar och Emballageinstruktioner

    M1-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Sarkat Sadi; Dennis Assmussen; [2014]
    Nyckelord :Quality; Packaging; Instructions; 7QC Tools; DMIAC; PDCA.; Kvalitet; Emballage; Instruktioner; 7QC-Verktyg; DMIAC; PDCA.;

    Sammanfattning : This report is the result of a thesis carried out at the Department of Innovation, Design and Technology (IDT), at Mälardalen University on behalf of ABB AB Machines.The year was 1988 when ASEA and Brown Boveri formed a joint venture under the name ABB (Asea Brown Boveri).

  7. 5. Motion controlled cleaning of large tanks

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Mattis Wahlby; [2013]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Reduction of the cleaning time is an important issue for companies using large tanks. A common solution is a stationary pipe going into the tank with a cleaning nozzle mounted on the end. Today the spray pattern of most cleaning systems is fixed. LÄS MER
