  1. 1. Using eye tracking to measure visual responses

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

    Författare :Sebaztian Johansson; Zebastian Kensert Forsman; [2023]
    Nyckelord :;

    Sammanfattning : Eye tracking technology is becoming more accessible in general, presenting new opportunities for applications. Said technology is also a relatively new and unexplored tool that can be used in research to enable insights not previously available. LÄS MER

  3. 2. Study of yield variation in a pharmaceutical manufacturing process and optimization of purification subsection : By a design of experiments study of the production parameters and a laboratory study of the purification step

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Sandra Lord; [2022]
    Nyckelord :Yield variations; activated carbon; pharmaceutical industry; purification; design of experiments; optimization; Utbytesvariation; aktivt kol; läkemedelsindustrin; reningssteg; experimentell design; optimering;

    Sammanfattning : The product R1-MR2E is an ester formed from an esterification of a carboxylic acid and an alcohol at Cambrex Karlskoga AB. The production of the intermediate R1-MR2E is a large-scale production and there are two main objectives and two sub-objectives that this project aims to study of the manufacturing. LÄS MER

  4. 3. Transesterifiering av rapsolja katalyserad av natriumdopad kalciumoxid

    Kandidat-uppsats, KTH/Kemi

    Författare :Ammar Anayi; Christoffer Ottenstedt; Ludvig Jöcker; [2022]
    Nyckelord :Biodiesel; FAME; Heterogen katalys; Katalysator; Rapsolja; Transesterifiering;

    Sammanfattning : The aim of this study was to find and use a heterogeneous catalyst to catalyze the transesterification reaction of biodiesel. The purpose of this is to have a more sustainable production of biodiesel which uses fewer chemicals and can reuse the catalyst easily. LÄS MER

    Sammanfattning : Norrvatten är den fjärde största dricksvattenproducenten i Sverige. De producerar och distribuerar dricksvatten till 14 kommuner norr om Stockholm. Norrvatten har under en tid studerat alternativa processer för att optimera och öka produktionskapaciteten och effektiviteten i deras dricksvattenreningsverk vid Görvälnverket. LÄS MER

  7. 5. Anti-lock braking system for bicycles

    Kandidat-uppsats, KTH/Mekatronik

    Författare :Kristian Jandric; Lucas Andersson; [2021]
    Nyckelord :Mechatronics; Bicycle; ABS; Arduino; Stepper motor; Brakes; Mekatronik; Cykel; ABS; Arduino; Stegmotor; Broms;

    Sammanfattning : An attempt was made to construct an ABS system that would both lock the wheel and release the brakes. The system would be mounted on a bicycle with v-brakes. It would then be tested if it could decrease the braking distance and if the system would respond fast enough. A literature study was made to learn what was needed for such a project. LÄS MER
