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

    University essay from Lunds universitet/Matematisk statistik

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

    Abstract : 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.

  3. 2. Aligning Mitre attack framework with threat analysis and risk assesment (TARA) to support R155 compliance

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Zainab Anifowose; [2023]
    Keywords : Automotive; Connected vehicle; TARA; ISO 21434; R155; MITRE;

    Abstract : Cyber security is evidently more important in todays and tomorrows connected and autonomous vehicles because the increasing connectivity in these vehicles is widening the vehicle attack surface area. Without having a cyber-secure vehicle, it is not possible to argue that connected and autonomous vehicles are safe for all road-users. READ MORE

  4. 3. You're On Your Own, Kid - A study of the impact of a change in remote working on affective commitment

    University essay from Handelshögskolan i Stockholm/Institutionen för marknadsföring och strategi

    Author : Lovisa Bergdahl; [2023]
    Keywords : Affective commitment; Remote working; Culture; Power distance; Job discretion;

    Abstract : Purpose: This study aims to investigate the impact of a change in remote working on affective commitment and what aspects influence the behavior of this relationship. Design/methodology/approach: Using a deductive quantitative approach, data from 507 participants from backgrounds with typically differing levels of power distance, namely India and the U. READ MORE

  5. 4. Estimation of blocked forces from a rear drive unit (RDU) in a test rig fixture

    University essay from KTH/Teknisk akustik

    Author : Sanjay Jayachandran; [2022]
    Keywords : Acoustics; Vibration; Sound; Mechanics; Blocked Forces; Transfer Path Analysis; Component-based TPA; Vibro-acoustics;

    Abstract : In the modern world, vehicle manufacturers are not the sole producer of every component in a vehicle but instead assign different subsystems to various OEMs (Original Equipment Manufacturer). Subsystems such as Rear Drive Units (RDU), Power Transfer Units (PTU), E-drives etc. are developed separately and then integrated into the main vehicle. READ MORE

  6. 5. Estimation of Blocked Forces in an Assembly with Rear Drive Unit as a Source

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Srujeeth Khanna Bala; [2021]
    Keywords : Component based TPA; source characterized forces; FEM; Contact forces; ISO20270:2019; Blocked forces; Automotive; NVH; sound and vibration; komponentbaserad TPA; karaktärisering av bullerkällor; FEM; kontaktkrafter; blockerade krafter; bilindustri; ljud och vibrationer; ISO20270:2019;

    Abstract : Experimental validations are widely used for studying dynamic structural behaviors and these studies involve defining the structures completely as being used in real time. While in numerical simulations such detailed features are not specified to ease the computation, thereby deviating from accurate results. READ MORE
