  1. 1. Randomized Diagonal Estimation

    University essay from KTH/Matematik (Avd.)

    Author : Niclas Joshua Popp; [2023]
    Keywords : Diagonal estimation; randomized numerical linear algebra; low-rank approximation; matrix functions; Diagonalestimering; randomiserad numerisk linjär algebra; lågrankad approximation; matrisfunktioner;

    Abstract : Implicit diagonal estimation is a long-standing problem that is concerned with approximating the diagonal of a matrix that can only be accessed through matrix-vector products. It is of interest in various fields of application, such as network science, material science and machine learning. READ MORE

  3. 2. Comparison of muscle oxygen kinetics between occluded and non-occluded dynamic low-intensity exercise performed till failure : A quantitative study

    University essay from Umeå universitet/Avdelningen för fysioterapi

    Author : Natalie Smith; Josefine Johansson; [2023]
    Keywords : venous occlusion; muscle oxygenation kinetics; blood flow restricted exercise; ischemia; exercise failure; low-intensity strength training; Near-infrared spectroscopy;

    Abstract : Aim: To examine local muscle oxygen kinetics when performing wrist extensions till failure in an occluded versus non-occluded state, to compare the perceived ratings of pain and local muscle exertion, and analysing presence of gender differences.

  4. 3. Perceived Liveliness Impact on Sense of Safety : A Study on Women’s Perceived Safety in Human-Lacking Urban Environments through Virtual Reality

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

    Author : Ebba Rovig; [2023]
    Keywords : Perceived liveliness; women’s perceived safety; natural surveillance; street attributes; presence of others; virtual reality; urban environments; Upplevd livlighet; kvinnors uppfattade trygghet; naturlig övervakning; gatuattribut; närvaro av människor; virtuell verklighet; urbana miljöer;

    Abstract : Denna avhandling undersökte förhållandet mellan urbana attribut och upplevd livlighet och dess effekt på kvinnors upplevda säkerhet. Med utgångspunkt i teorier om naturlig övervakning [6] och vikten av att ha andra människor närvarande för att öka kvinnors säkerhet [17], utvärderades fysiska gatuattribut som förutspåddes öka miljöns livlighet.

  5. 4. Determining the Optimal Frequencies for a Duplicated Randomized Clock SCA Countermeasure

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

    Author : Gabriel Klasson Landin; Truls Julborg; [2023]
    Keywords : Side channel attack; Cryptography; Correlation power analysis; Chipwhisperer; Frequency; Hardware security;

    Abstract : Side-channel attacks pose significant challenges to the security of embedded systems, often allowing attackers to circumvent encryption algorithms in minutes compared to the trillions of years required for brute-force attacks. To mitigate these vulnerabilities, various countermeasures have been developed. READ MORE

  6. 5. THE EFFECTS OF MINDFUL MEDITATION AND CYCLIC HYPERVENTILATION WITH RETENTION ON INTEROCEPTION IN HEALTHY ADULTS : A STUDY ON HEART RATE VARIABILITY AND INTEROCEPTIVE CAPACITY

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Villiam Bornström; [2023]
    Keywords : Interoception; Homeostasis; Heartrate Variability;

    Abstract : The aim of this study was to investigate the comparative effects of mindful meditation and cyclic hyperventilation with retention upon interoceptive ability and heart rate variability (HRV). Further studies comparing meditation and breathwork contribute to a greater understanding of their potential benefits and have the potential to enhance overall well-being in the general population.
