  1. 21. Load-current response to severe changes of voltage

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Shuhan Ma; [2017]
    Keywords : ;

    Abstract : Electric loads, such as computers, lamps, refrigerators and heaters connected to low-voltage distributionsystems in homes and offices differ widely in how their current responds to changes in the applied voltage.These voltage changes could be a total collapse of the voltage, a weak or strong reduction of amplitude,or a sudden phase-shift.

  3. 22. Assessing the ability of HEC-HMS rainfall-runoff model to simulate stream flow across Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Mohammadreza Alavimoghaddam; [2017]
    Keywords : Rainfall-Runoff; HEC-HMS; Sweden;

    Abstract : Computer modeling is the powerful tool for simulating nature’s behavior; however, still more efforts are need for reaching perfect simulation with computer models (especially in the hydrological field of study). In this Master’s thesis, the accuracy of the HEC-HMS computer model for long term rainfall-runoff simulation was evaluated across Sweden. READ MORE

  4. 23. Electric Motor Controlled Joint Simulator

    University essay from Linköpings universitet/Reglerteknik

    Author : Sofie Griph; [2016]
    Keywords : control; electric motor; modeling; simulation; joint; screw joint; tightening;

    Abstract : Tightening systems are used in several industries, including assembly in the auto- motive industry and installation of computer hardware. Both the company mak- ing the tools and the customers need to know the performance of the tightening system to ensure that the screw joints tighten as desired. This can be done using a test joint system. READ MORE

  5. 24. Comparative simulation of heat transfer in a cylinder of phase changing material : How does the orientation impact the energy discharge?

    University essay from KTH/Industriell ekologi

    Author : Niklas Brännlund; Joakim Henriksson; [2016]
    Keywords : ;

    Abstract : A computer simulation was done in COMSOL Mulitphysics 5.1, on heat transfer in rods filled with phase change material (PCM). The main objective was to compare the rods rate of heat transfer at two different orientations, horizontal and vertical. READ MORE

  6. 25. Bucket-soil interaction for wheel loaders : An application of the Discrete Element Method

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Felix Henriksson; Joanna Minta; [2016]
    Keywords : Discrete element method; multibody system; wheel loader; soil-tool interaction; co-simulation interval; gravel pile; collision detection interval; normal stiffness;

    Abstract : Wheel loaders are fundamental construction equipment to assist handling of bulk material e.g. gravel and stones. During digging operations, it withstands forces that are both large and very complicated to predict. READ MORE
