  1. 1. Portfolio Optimization Problems with Cardinality Constraints

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Abolgasem Esmaeily; Felix Loge; [2023]
    Keywords : Portfolio Optimization; Modern Portfolio Theory MPT • Mixed Integer Programming MIP ; Efficient Frontier; Cardinality Constraints; Daily Returns; Expected Returns; Asset Allocation; Diversification;

    Abstract : This thesis analyzes the mean variance optimization problem with respect to cardinalityconstraints. The aim of this thesis is to figure out how much of an impact transactionchanges has on the profit and risk of a portfolio. We solve the problem by implementingmixed integer programming (MIP) and solving the problem by using the Gurobi solver. READ MORE

  3. 2. Abstract Logics and Lindström's Theorem

    University essay from Uppsala universitet/Algebra, logik och representationsteori

    Author : Niclas Bengtsson; [2023]
    Keywords : model theory; abstract model theory; logic; mathematical logic; abstract logic; Lindström s Theorem; infinitary logics; strength of logics; cardinality quantifiers; modellteori; abstrakt modellteori; logik; matematisk logik; abstrakt logik; Lindströms sats;

    Abstract : A definition of abstract logic is presented. This is used to explore and compare some abstract logics, such as logics with generalised quantifiers and infinitary logics, and their properties. Special focus is given to the properties of completeness, compactness, and the Löwenheim-Skolem property. READ MORE

  4. 3. A Study on Poset Probability

    University essay from Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Author : Albin Jaldevik; [2022]
    Keywords : Discrete mathematics; Order theory; Combinatorics; Partially ordered set; Poset; Linear extension; Topological sorting; Probability; Partition; Young diagram;

    Abstract : Let be a finite poset (partially ordered set) with cardinality . A linear extension of is an order-preserving bijection : , that is, if in then . We define the poset probability as the proportion of linear extensions where . We are primarily interested in for incomparable elements . READ MORE

  5. 4. A systematic mapping study of mapping modelling languages

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Marija Popovic; Amila Cizmic; [2022]
    Keywords : mapping; mapping model; mapping metamodel; mapping language;

    Abstract : Context - Various research teams, as well as individual researchers, have investigated mapping modelling languages. However, systematic studies that provide a structured overview of this research on this topic have not been conducted. It is noticeable that this leaves a big gap in the context of a modelling language. READ MORE

  6. 5. A Real- time Log Correlation System for Security Information and Event Management

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

    Author : Clémence Dubuc; [2021]
    Keywords : Correlation; SIEM; Security Logs; Apache Spark; Elastic Search; Korrelation; SIEM; Säkerhetsloggar; Apache Spark; Elastic Search;

    Abstract : The correlation of several events in a period of time is a necessity for a threat detection platform. In the case of multistep attacks (attacks characterized by a sequence of executed commands), it allows detecting the different steps one by one and correlating them to raise an alert. READ MORE
