  1. 1. The quest for a classical bulge - a study of kinematics, abundances, and ages using microlensed dwarf stars and Gaia

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Calum Kvernes Macpherson; [2023]
    Nyckelord :Bulge; Milky Way; Kinematics; Galpy; Dwarf Stars; Physics and Astronomy;

    Sammanfattning : Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter.

  3. 2. Study of evaluation metrics while predicting the yield of lettuce plants in indoor farms using machine learning models

    Magister-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Divya Chedayan; Harry Geo Fernandez; [2023]
    Nyckelord :machine learning; lettuce yield prediction; Regression; SVR; RF; DNN; MAE; MSE; RMSE; R-squared; Adjusted R-squared;

    Sammanfattning : A key challenge for maximizing the world’s food supply is crop yield prediction. In this study, three machine models are used to predict the fresh weight (yield) of lettuce plants that are grown inside indoor farms hydroponically using the vertical farming infrastructure, namely, support vector regressor (SVR), random forest regressor (RFR), and deep neural network (DNN).

  4. 3. Assessing Supply Chain Resilience to Mitigate Supply Chain Risks : A case study of the inbound logistics @ Volvo CE

    Master-uppsats, Linköpings universitet/Logistik- och kvalitetsutveckling

    Författare :Emma Fridolfsson; Lova de Man Lapidoth; [2023]
    Nyckelord :supply chain resilience; SCRES; supply chain risk; supply chain risk management; supply chain disruption; risk sources; risk drivers; resilience capabilities; SCRES elements; risk mitigation strategies;

    Sammanfattning : In recent years, the frequency of disruptive events in supply chains has increased. This is partly due to the fact that supply chains are more globalized and more complex, with deeper tiering among suppliers. This makes the supply chain more vulnerable to risks. LÄS MER

  5. 4. Uncertainty Analysis : Severe Accident Scenario at a Nordic Nuclear Power Plant

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Josefin Hedly; Mikaela De Young; [2023]
    Nyckelord :Nuclear power plant; microdata analysis; Random Forest; k-Nearest Neighbor; SVM;

    Sammanfattning : Nuclear Power Plants (NPP) undergo fault and sensitivity analysis with scenario modelling to predict catastrophic events, specifically releases of Cesium 137 (Cs-137). The purpose of this thesis is to find which of 108 input-features from Modular Accident Analysis Program (MAAP)simulation code are important, when there is large release of Cs-137 emissions. LÄS MER

  7. 5. Cross region cloud redundancy : A comparison of a single-region and a multi-region approach

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Oskar Lindén; [2023]
    Nyckelord :Cloud computing; Cross-region replication; Performance evaluation;

    Sammanfattning : In order to increase the resiliency and redundancy of a distributed system, it is common to keep standby systems and backups of data in different locations than the primary site, separated by a meaningful distance in order to tolerate local outages. Nasdaq has accomplished this by maintaining primary-standby pairs or primary-standby-disaster triplets with at least one system residing in a different site. LÄS MER
