  1. 11. Produktion av biofilm med MRSA, MRSP eller Campylobacter jejuni, samt hur olika desinfektionsmedel påverkar den

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Moa Therése Viklund; [2022]
    Keywords : biofilm; destruktion av biofilm; Campylobacter jejuni; stafylokocker; MRSA; MRSP; desinfektion; rengöring; peroxymonosulfat buffrade syror; perättiksyra; väteperoxid; hypoklorsyra; etanol;

    Abstract : I denna studie ingick såväl produktion av biofilm i en statisk modell med mikrotiterplattor där biofilmen fick växa ostört i 5 dagar i inkubationsskåp i 30 °C, samt en mer dynamisk modell. I den dynamiska modellen ingick vattenledningsrör där buljong och bakterier växt i inkubationsskåp i 30 °C i 5 dagar för att sedan stå i rumstemperatur i ytterligare 5 dagar med daglig skakning i en timme, samt att buljong byttes ut vid dag 5 och nya bakterier tillsattes dag 7.

  2. 12. Housing Price Prediction over Countrywide Data : A comparison of XGBoost and Random Forest regressor models

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Erik Henriksson; Kristopher Werlinder; [2021]
    Keywords : Random Forest; XGBoost; predicting housing prices; feature engineering; ensemble learning; boosting; data cleansing; 5foldcrossvalidation.;

    Abstract : The aim of this research project is to investigate how an XGBoost regressor compares to a Random Forest regressor in terms of predictive performance of housing prices with the help of two data sets. The comparison considers training time, inference time and the three evaluation metrics R2, RMSE and MAPE. READ MORE

  3. 13. Predicting Buffer Status Report (BSR) for 6G Scheduling using Machine Learning Models

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Qi Zhang; [2021]
    Keywords : Buffer Status Report; 6G scheduling; Machine Learning; Uplink Traffic Prediction; Wireless Communication; Buffert status rapport; 6G-schemaläggning; Machine Learning; Uplink Traffic Prediction; Wireless Communication;

    Abstract : In 6G communication, many state-of-the-art machine learning algorithms are going to be implemented to enhance the performances, including the latency property. In this thesis, we apply Buffer Status Report(BSR) prediction to the uplink scheduling process. The BSR does not include information for data arriving after the transmission of this BSR. READ MORE

  4. 14. Laser ablation of aluminium before welding : Effect of weld preparation on number and sizes of pores

    University essay from KTH/Materialvetenskap

    Author : Olivia Taivalkoski; [2021]
    Keywords : ;

    Abstract : Welding aluminium often results in porosity in the weld. One way to reduce porosity is by carful weld preparation and cleaning. In this master thesis report laser ablation was done on aluminium plates before welding to remove dirt and the surface oxide layer. READ MORE

  5. 15. Understanding particulate matter - Material analyses of real-life diesel particulate filters and correlation to vehicles’ operational data

    University essay from KTH/Kemiteknik

    Author : Linus Nordin; [2021]
    Keywords : Diesel particulate filter; Ash measurement method development; Correlation study; Operational parameters; Principal component analysis; Dieselpartikelfilter; Askanalys metodutveckling; Korrelationsstudie; Driftsparametrar; Principal component analysis;

    Abstract : Syftet med denna studie var att undersöka effekterna av driftsparametrar på ett antal mätbara askrelaterade parametrar i dieselpartikelfilter (DPF) i tunga fordon. Tidigare studier visar att askans packningsdensitet, askflöde och hur askan fördelas inuti ett DPF är beroende av parametrar som temperatur, avgasflöde och oljeförbrukning ett fordon har. READ MORE
