  1. 1. Real time estimations of kLa and viscosity in a fermentation pilot plant

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Arvid Norberg; [2022]
    Nyckelord :Oxygen transfer; Viscosity; Fermentation; Biotechnology; Direct method; kLa; OUR; DO; Online monitoring; Soft sensor; Fungus; Fungal fermentation; A. oryzae; A. niger; Herschel-Bulkley; Power law; Shear thinning; Novozymes; Enzymes; Technology and Engineering;

    Sammanfattning : Fermentation is a process that utilizes live microorganisms to produce different biological products such as enzymes. The oxygen mass transfer rate is often the limiting factor in aerobic fermentations and thereby an important process parameter. LÄS MER

    Sammanfattning : Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissions by changing the traffic signal programs.

  4. 3. Goodness-of-fit Tests for Time Dependent Ensemble Averages

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Jake Lumsden; [2022]
    Nyckelord :Physics and Astronomy; Mathematics and Statistics;

    Sammanfattning : Fitting a model to a time-dependent ensemble average is a process repeated frequently throughout biophysics. A selected ensemble-averaged observable (⟨y(t)⟩) for a given system can be predicted through the use of an estimated ensemble average, where the estimated ensemble average is created via simulated or experimental data sets.

  5. 4. An Automated Methodology for Identification and Analysis of Erroneous Production Stop Data

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Sopal Soman; [2020]
    Nyckelord :;

    Sammanfattning : The primary aim of the project is to automate the process of identifying erroneous entries in stop data originating from a given production line. Machines or work stations in a production line may be stopped due to various planned (scheduled maintenance, tool change, etc.) or unplanned (break downs, bottlenecks, etc.) reasons. LÄS MER

  7. 5. Undersökning av skillnader mellan planerad och verklig produktionstid : – En fallstudie hos AQ Group i Pålsboda

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för industriell ekonomi, industridesign och maskinteknik

    Författare :Adrian Hamryni; Dahir Mohamed Ibrahim; [2020]
    Nyckelord :Lean; 5S; cycle time; cycle time variance; production planning; production time variability; production time estimation; production planning; setup time;

    Sammanfattning : På senaste tiden har leveransprecision blivit allt viktigare eftersom kunder idag kännetecknas av att vara mer tidskänsliga och ständigt söker efter produkter som är specifikt anpassade till kunden. Tid har därmed betraktats som ett kriterium för konkurrens och är betydande för företag att kunna konkurrera på marknaden. LÄS MER
