  1. 1. Usability Testing of Software Products : A case study about usability testing and how to improve the practice

    Kandidat-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Alice Hällkvist; [2019]
    Nyckelord :;

    Sammanfattning : Usability testing is an important task during development of software products such as web and mobile applications. It is a growing and evolving concept but is often left out during development due to time and costs. Developers are also expected to handle the usability testing but are given minimal training to do so. LÄS MER

  2. 2. Uppföljning av absoluta tjälrörelser : En fallstudie av väg E10 i Kiruna

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Hampus Elmehög; [2019]
    Nyckelord :frost; frost heave; PMS objekt; road construction; segregation potential theory; PMS objekt; segregation potential theory; tjäle; tjällyftning; vägbyggnad;

    Sammanfattning : Detta examensarbete har haft som mål att undersöka tjällyftningen hos en väg i en fältstudie och utvärdera reliabiliteten hos två olika modeller för skattning av tjällyftning. Modellerna som har studerats är Trafikverkets nuvarande, vilken är implementerad i deras vägdimensioneringsverktyg PMS Objekt, samt segregation potential theory. LÄS MER

  3. 3. Development and Implementation of a Mass Balancing System for CubeSat Attitude Hardware-in-the-Loop Simulations

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Guillermo Ledo López; [2019]
    Nyckelord :hil; hardware in the loop; simulation; satellite; simulator; platform; simulink; matlab; least squares; aocs; testing; attitude; dynamics; control;

    Sammanfattning : Spacecraft simulator platforms can simulate the microgravity environment of space on Earth, for the purposes of testing the Attitude and Orbit Control Subsystem of satellites. In order to do this, the satellite is mounted on a bench and the combined center of mass of this assembly is controlled by a series of moving masses. LÄS MER

  4. 4. Automated Simulation and Parameter Estimation of Chromatography Processes

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Johan Olsson; [2019]
    Nyckelord :chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : Preparative chromatography is an important separation technique in downstream processing for several industries. It has the ability to separate two or more component from each other to achieve high purity. LÄS MER

  5. 5. Implementation and Evaluation of Encoder Tools for Multi-Channel Audio

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik
