  1. 11. Covariance Matrix Regularization for Portfolio Selection: Achieving Desired Risk

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Manu Upadhyaya; [2020]
    Nyckelord :covariance matrix; portfolio selection; risk; Mathematics and Statistics;

    Sammanfattning : The modus operandi of most asset managers is to promise clients an annual risk target, where risk is measured by realized standard deviation of portfolio returns. Moreover, Markowitz (1952) portfolio selection requires an estimate of the covariance matrix of the returns of the financial instruments under consideration. LÄS MER

  3. 12. Binary classification of HRV signals

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Rebecca Lütz; [2019]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Heart rate variability, commonly abbreviated as HRV, displays the variance between consecutive heartbeats. This variance occurs naturally but can change due to stress and problems with the cardiac system. HRV is therefore widely used for medical research. LÄS MER

  4. 13. Framtidsutsikter för pastoralism på Kenyanska betesmarker

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Zebastian Cederblad; [2019]
    Nyckelord :Kenya; ; kenyanska betesmarker; pastoralism; zebu; boskap; landfragmentering; klimatförändringar;

    Sammanfattning : Pastoralism är ett system där majoriteten av en individs inkomst och mat kommer från boskapsdjur. Boskapsdjurens huvudsakliga matkälla är naturligt växande bete. Pastoralism kan delas in i tre huvudtyper; nomadisk, transhuman och stillasittande. I Kenya finns variationer av alla tre. LÄS MER

  5. 14. Exploration of an all-atom thermodynamic model to predict site-specific evolutionary rates in proteins

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Fábio Dias Correia de Oliveira; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Understanding the patterns of evolutionary sequence divergence is fundamental for comparative analyses like phylogenetics or genomics. The rate at which the different sites of protein sequences evolve is multifactorial and the causes of variation among them are highly convoluted. LÄS MER

  7. 15. Investigation about the Lead Time Variability at Warehouse A Case Study of the Central Warehouse of Company Y

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Abudushalamu Abudurexiti; Mijanur Rahman; [2018-07-02]
    Nyckelord :Aftermarket Supply Chain; Lead Time Variability; Warehouse Management;

    Sammanfattning : The lack of previous studies regarding the understanding of distinction and relationship between effective and efficient measurements of supply chain performance led this report to create a framework based on various literatures of the two concepts, including Potočan (2006)’s claim on the sources of conflict in content understanding, implementation of methodologies and management of organizations’ operations. By initiating the analyses on the lead time deviation in the Company Y, a major manufacturing company for commercial vehicles, and its influence on various performance measurements at different levels, the connection is endeavored as the lead time being an effective measurement and other time dependent measurements being efficient ones.
