  1. 1. Computational Fluid Dynamics and Modeling of a Free Surface Flow

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Mathieu Marmier; [2023]
    Nyckelord :CFD; Free Surface Flow; VOF; STAR-CCM ; Multiphase Simulation; Nuclear Engineering; Fluid Mechanics;

    Sammanfattning : This project deals with the CFD modelling of a free surface flow. The aim is to develop and validate a fast and accurate numerical model for stratified two-phase flows. Volume of Fluid (VOF) multiphase model is employed. The purpose is to use the developed numerical model for the design of an element within a compact nuclear reactor. LÄS MER

  3. 2. Beam Steering Antenna Based on Continuous Transverse Stub Array and Flat Risley Prism Metasurface Lens

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

    Författare :Carl Henriksson; Jonathan Fransson; [2023]
    Nyckelord :;

    Sammanfattning : Satellite communication is an integral part of society in this day and era. Due tobandwidth limitations communication frequencies have moved into higher frequencybandwidths. With the advancements in communication comes the demand for more efficientantennas due to the high attenuation of millimeter wavelength frequencies. LÄS MER

  4. 3. Sensorless Hybrid Field-Oriented Control Two-Phase Stepper Motor Driver

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Emil Lydell; [2023]
    Nyckelord :Stepper motor; Field-Oriented Control; FOC; Driver; Two-Phase; 2-Phase;

    Sammanfattning : Hybrid stepper motors are small electrical motors with high torque production, compared with other electrical motors of the same size. Hybrid stepper motors are reliable in open-loop systems, in Sinusoidal mode, but with a drawback of high power consumption. LÄS MER

  5. 4. Virtual Sensing for Cluster Vacuum Control

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Carl Egenäs; Axel Sacilotto; [2023]
    Nyckelord :;

    Sammanfattning : The purpose of this project was to develop a virtual sensing model in order to estimate the vacuum level in the milking cluster with data collected further along the milk tube. Measuring the cluster vacuum level is desirable for many applications, such as control and monitoring, but due to the cow's tendency to kick, chew and stomp on anything within reach, placing a sensor in or close to the cluster is both difficult and impractical.

  7. 5. Enhancing Brand Experience Through UI Elements Aligned With Brand Values : An Investigation of the Interconnected Fields of User Experience and Brand Experience Within the Context of IKEA’s E-commerce Website

    Magister-uppsats, Jönköping University/JTH, Avdelningen för datateknik och informatik

    Författare :Ráhel Anna Balogh; Máté Kézy; [2023]
    Nyckelord :user experience design; user interface design; visual design; brand experience; e-commerce website; hedonic quality; brand values; UI elements;

    Sammanfattning : In today’s competitive landscape, shaping positive digital experiences with the brand is crucial for the company’s market success. The study aimed to investigate the interconnected relationship between User Experience (UX) and Brand Experience (BX) by exploring the potential for enhancing BX through the implementation of User Interface (UI) elements aligned with brand values within an e-commerce website.
