  1. 1. Simulation of FMCW mode MIMO Radar for Performance Analysis as Industrial Safety System

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jay Prakash; [2021]
    Nyckelord :Industrial safety; SIL; radar; MIMO; FMCW; EM scattering; FEM; Tissue permittivity; Radar cross section; CFAR; maskinsäkerhet; SIL; radar; MIMO; FMCW; elektromagnetisk spridning; FEM; Tissue permittivitet; Radar cross section; CFAR;

    Sammanfattning : In industrial environments workers can be prone to dangerous situations that may cause harm. In order to prevent accidents and fulfill legislative requirements for safe working condition, a safety system can be needed to be installed in place. LÄS MER

  3. 2. Clustering of Financial Account Time Series Using Self Organizing Maps

    Master-uppsats, KTH/Matematisk statistik

    Författare :Magnus Nordlinder; [2021]
    Nyckelord :Kohonen; financial accounts; self organizing maps; clustring; time series; Kohonen; finansiella konton; klustring; tidsserier;

    Sammanfattning : This thesis aims to cluster financial account time series by extracting global features from the time series and by using two different dimensionality reduction methods, Kohonen Self Organizing Maps and principal component analysis, to cluster the set of the time series by using K-means. The results are then used to further cluster a set of financial services provided by a financial institution, to determine if it is possible to find a set of services which coincide with the time series clusters.

  4. 3. Churn Prediction

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Alexander Åkermark; Mattias Hallefält; [2019]
    Nyckelord :Churn Prediction; Machine Learning;

    Sammanfattning : Churn analysis is an important tool for companies as it can reduce the costs that are related to customer churn. Churn prediction is the process of identifying users before they churn, this is done by implementing methods on collected data in order to find patterns that can be helpful when predicting new churners in the future.

  5. 4. Alternative Methods of Estimating Investor´s Risk Appetite

    Master-uppsats, KTH/Matematisk statistik

    Författare :Felix Kuritzén; [2019]
    Nyckelord :Risk appetite; Riskaptit;

    Sammanfattning : In this thesis three risk appetite indexes are derived and measured from the beginning of 2006 to the end of the first quarter in 2019. One of the risk appetite indexes relies on annualized returns and volatilities from risky and safe assets while the others relies on subjective and risk neutral probability distributions. LÄS MER

  7. 5. Know the flow - spatial and temporal variation of DOC exports and the importance of monitoring site specific discharge

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Johannes Larson; [2018]
    Nyckelord :dissolved organic carbon; DOC; export; boreal; specific discharge; spatiotemporal variation; löst organiskt kol; DOC; export; boreal; specifik avrinning; spatiotemporal variabilitet;

    Sammanfattning : The export of dissolved organic carbon (DOC) is an important component in both water quality and carbon cycling within boreal catchments. DOC exports are mainly controlled by discharge. LÄS MER
