    Författare :Alex Holm; Ellioth Tilly; Thomas Eklind; [2023-09-01]
    Nyckelord :Momentum strategies; Volatility; Excess return; Jensen s Alpha; Covid -19. 1;

    Sammanfattning : The momentum strategy is a widely recognized investment approach that aims to generate abnormal returns by buying past winners and selling past losers. The purpose of this thesis is to investigate if the momentum strategy is applicable at Swedish industries and see if there are any differences between a longer and shorter holding and ranking period.

  4. 3. Time-based Key for Coverless Audio Steganography: A Proposed Behavioral Method to Increase Capacity

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :John Alanko Öberg; Carl Svensson; [2023]
    Nyckelord :Coverless audio steganography; information hiding; covert communication; effective capacity; behavioral; Täcklös ljudsteganografi; informationsdöljning; hemlig kommunikation; effektiv kapacitet; beteendemässig;

    Sammanfattning : Background. Coverless steganography is a relatively unexplored area of steganography where the message is not embedded into a cover media. Instead the message is derived from one or several properties already existing in the carrier media. This renders steganalysis methods used for traditional steganography useless. LÄS MER

  5. 4. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Jessica McKenna; [2023]
    Nyckelord :Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Sammanfattning : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.
