  1. 1. XZDDF Bootstrapping in Fully Homomorphic Encryption

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Simon Ljungbeck; [2024]
    Nyckelord :Fully Homomorphic Encryption; Homomorphic Encryption; Bootstrapping; Blind Rotation; XZDDF; Technology and Engineering;

    Sammanfattning : Despite the vast research on the topic in recent years, fully homomorphic encryption schemes remain time-inefficient. The main bottleneck is the so-called bootstrapping, whose purpose is to reduce noise that has accumulated after having performed homomorphic operations on a ciphertext. LÄS MER

  3. 2. Work-life balance och motivation : En kvantitativ studie som undersöker sambandet mellan work-life balance och medarbetarnas upplevda motivation

    Kandidat-uppsats, Högskolan Väst/Institutionen för individ och samhälle

    Författare :Amanda Martins; Frida Schaffer; [2023]
    Nyckelord :Work-life balance; motivation; work motivation; balance between work and personal life; intention to leave work; conflict theory; SDT theory; Work life balance; motivation; arbetsmotivation; balansen mellan arbetsliv och privatliv; viljan att lämna arbetet; konfliktteorin; SDT-teorin;

    Sammanfattning : Bakgrund. Individer i dagens samhälle behöver finna en balans mellan sina olika roller inom arbetslivet och privatlivet. Denna balans konkurrerar om individens tid och resurser, vilket kan vara krävande för en individ att lyckas balansera mellan. LÄS MER

  4. 3. Bootstrapping methods for assessing causality in survival analysis: A case study on major adverse cardiovascular events

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Paulina Benthem Ciano; [2023]
    Nyckelord :Causality; Graphical models; Bootstrap; Survival analysis; Additive hazards model.; Mathematics and Statistics;

    Sammanfattning : The combination of graphical models with Aalen's additive hazards model, resulting in a model known as dynamical path analysis, permits assessing the effects of different variables on times until an event and decomposing these total effects into direct and indirect effects. This thesis proposes novel bootstrapping methods designed for left-truncated right-censored data, conditional on covariates within the framework of Aalen's additive hazards model, in order to obtain confidence intervals for the estimates.

  5. 4. Evaluating Bag Of Little Bootstraps On Logistic Regression With Unbalanced Data

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Henrik Bark; [2023]
    Nyckelord :Bootstrapping; Logistic Regression; Bag of Little Bootstraps; BLB; Penalized Maximum Likelihood Estimation; PMLE;

    Sammanfattning : The Bag of Little Bootstraps (BLB) was introduced to make the bootstrap method more computationally efficient when used on massive data samples. Since its introduction, a broad spectrum of research on the application of the BLB has been made. LÄS MER

  7. 5. Investigating the Estimation of the infection rate and the fraction of infections leading to death in epidemiological simulation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Jakob Gölén; [2023]
    Nyckelord :Epidemics; Compartmental Models; Parameter Inference; Synthetic Bootstrap; Infection Rate;

    Sammanfattning : The main goal of this project is to investigate the behaviors of parameters used when modeling an epidemic. A stochastic SIHDRe model is used to simulate how an epidemic evolves over time. LÄS MER
