    Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

    Författare :Hugo Jidberg; Elias Schön; [2023]
    Nyckelord :Energy; energy efficiency; color rendition; light level; saturation; security; TM-30-20; safety; Energi; energieffektivitet; färgåtergivning; ljusnivå; mättnad; säkerhet; TM-30-20; trygghet;

    Sammanfattning : The high electricity prices are a talked about issue in today's society where many peoplefind themselves in a critical situation as a result of them. In a more long-termperspective, Sweden faces a goal of a comprehensive transformation of the energysystem. Lighting is a contributing factor to the energy system and energy use. LÄS MER

  3. 2. Improving Visibility Forecasts in Denmark Using Machine Learning Post-processing

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :August Thomasson; [2023]
    Nyckelord :visibility forecast; fog; machine learning; numerical weather predicition; XGBoost; Random Forest; siktprognos; dimma; maskininlärning; numerisk vädermodell; XGBoost; Random Forest;

    Sammanfattning : Accurate fog prediction is an important task facing forecast centers since low visibility can affect anthropogenic systems, such as aviation. Therefore, this study investigates the use of Machine Learning classification algorithms for post-processing the output of the Danish Meteorological Institute’s operational Numerical Weather Prediction (NWP) model to improve visibility prediction.

  4. 3. Forecasting Inventory Quantities : Time Series Models for Visualizing Fluctuations within Outbound Logistics

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Johan Lagerström; Lisa Sundström; [2022]
    Nyckelord :Outbound Logistics; Forecasting; Fluctuations; Time Series Analysis; Inventory space; 3PL;

    Sammanfattning : Forecasting demand is one of the processes which greatly influences the decision making within a company, and it is also one of the greatest sources of uncertainty. Inaccurate forecasts force companies to find ways to compensate for the uncertainty, often by building inventories. LÄS MER

  5. 4. Root Cause Analysis for In-Transit Time Performance : Time Series Analysis for Inbound Quantity Received into Warehouse

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Raman Ali; [2021]
    Nyckelord :Logistic; Time Series; Forecast; Inbound logistics; In-Transit;

    Sammanfattning : Cytiva is a global provider of technologies to global pharmaceutical companies and it is critical to ensure that Cytiva’s customers receive deliveries of products on-time. Cytiva’s products are shipped via road transportation within most parts of Europe and for the rest in the world air freight is used. LÄS MER

  7. 5. Verification of HARMONIE-AROME, ECMWF-IFS and WRF: Visibility and Cloud Base Height

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Elin Kindlundh; [2020]
    Nyckelord :HARMONIE-AROME; ECMWF-IFS; WRF; verification; visibility; cloud base height; HARMONIE-AROME; ECMWF-IFS; WRF; verifikation; sikt; molnbashöjd;

    Sammanfattning : Visibility and cloud base height are two important parameters within aviation meteorology and verification of operational numerical weather prediction (NWP) models with regard to these two parameters is therefore important. Visibility is often parameterized through an extinction coefficient, which is dependent on for example liquid or ice water content, however it also depends on the humidity, precipitation intensity and particle concentration.
