    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Johanna Swanelius; [2022]
    Nyckelord :Microfibrillated cellulose; MFC; waxy maize starch; rheology; temperature; viscosity; complex viscosity; stready shear viscosity curve; amplitude sweep; dry content; dynamic rotational rheometer; Mikrofibrillerad cellulosa; MFC; vaxartad majsstärkelse; reologi; temperatur; viskositet; komplex viskositet; flödeskurva; amplitudsvep; torrhalt; dynamisk reometer;

    Sammanfattning : Today, the focus lies on the state of the environment and how we can choose more sustainable alternatives to oil based materials. One material of interest is microfibrillated cellulose (MFC). LÄS MER

  3. 2. Evaluation of Traction Control Systems for an Electric Forklift Truck

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Mattias Karlsson; Sebastian Johansson; [2021]
    Nyckelord :forklift; traction control; maximum transmissible torque; model following control; sliding mode control; slip; asr; tcs; mfc; mtte; smc; electric vehicle; master thesis;

    Sammanfattning : This thesis evaluates different controllers for traction control on an electric forklift truck and has been done in cooperation with Toyota Material Handling Manufacturing Sweden. The need for a traction control system has increased with the introduction of lithium-ion batteries replacing the older lead-acid batteries, reducing the battery weight and therefore the downward force on the driving wheel increasing the risk for slip.

  4. 3. Biomimetically improved materials comprising microfibrillated cellulose

    Master-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Cornelia Byström; [2021]
    Nyckelord :;

    Sammanfattning : Microfibrillated cellulose (MFC) is a renewable, cellulosic material mainly producedfrom wood fibers, which are found in the secondary cell walls of plant cells. With theincreased demand for renewable biopolymer films in packaging, MFC has emerged asa potential alternative to non-renewable polymer films. LÄS MER

  5. 4. Modelling and design of PMSM position drivesusing model following control

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

    Författare :JACOB RÖING; CARL JENSEN; [2021]
    Nyckelord :;

    Sammanfattning : Teenage Engineering is a Swedish electronics company that want to automate their quality control process. For this purpose, they want to develop a test jig that can perform tactile testing of their products. The test jig will utilize PMSM motors for position control of the end-effector. LÄS MER

  7. 5. CORRELATIONS BETWEEN PHYSICOCHEMICAL PROPERTIES IN MATERIALS COMPRISING MICROFIBRILLATED CELLULOSE : CORRELATIONS BETWEEN PHYSICOCHEMICAL PROPERTIES IN MATERIALS COMPRISING MICROFIBRILLATED CELLULOSE

    Master-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Johanna Nilsson; [2021]
    Nyckelord :;

    Sammanfattning : Microfibrillated cellulose (MFC) films have gained a lot of industrial interest lately dueto their good barrier properties and good mechanical strength. In this study it wasinvestigated whether rheological characteristics and conductivity of MFC dispersionscomprised of different MFC grades could be correlated to tensile properties of the MFCfilms produced from the corresponding MFC dispersion.
