  1. 1. A REVIEW OF PHYSICAL ACTIVITY’S EFFECT ON MOOD Through the Lens of the HPA Axis

    Kandidat-uppsats, Institutionen för tillämpad informationsteknologi

    Författare :Susanna Karlkvist; Anton Wickberg; [2023-02-01]
    Nyckelord :Mood; Physical activity; HPA axis; The cross-stressor adaptation hypothesis; CRH; Exercise; Cortisol; Cognition;

    Sammanfattning : Engagement in physical activity (PA) has been said to trigger a chain reaction of events which can alter our mood state. One recently implicated component is the hypothalamic-pituitary-adrenal (HPA) axis, involved in the reaction to physical and psychological stress-ors. LÄS MER

  3. 2. Analog mixed signal front-end for Torque signal processing : A theoretical noise analysis and signal-chain evaluation

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jesper Jansson; Wilhelm Nordgren; [2023]
    Nyckelord :Torque sensor; noise analysis; signal processing; analog-to-digital conversion; Momentgivare; brusanalys; signalbehandling; analog-till-digital omvandling;

    Sammanfattning : High precision tightening of nuts and bolts together with traceability are important in many industrial assembly lines. To achieve this the nutrunner needs to accurately measure the torque which is applied to the nut, process the signal and provide the information to the controller that controls the tightening process.

  4. 3. Moderling Acoustic Transmission in Towed Array Sonars : Computations of the coupled acoustic and elastic wave equations

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Bill Claesson; [2023]
    Nyckelord :;

    Sammanfattning : This thesis presents a method of solving the Helmholtz equation coupled with the Navier-Cauchy equation over a cross section of a Towed Array Sonar (TAS) modeled as a simplified cylindrical shell. The purpose of solving these equations is to estimate the transfer function of the pressure between the outside boundary and a position inside the TAS. LÄS MER

  5. 4. Performance metrics and velocity influence for point cloud registration in autonomous vehicles

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Óscar Poveda Ruiz; [2023]
    Nyckelord :autonomous vehicle; localization; registration; metrics; error; classification; estimation; autonomt fordon; lokalisering; registrering; mätvärden; fel; klassificering; uppskattning;

    Sammanfattning : Autonomous vehicles are currently under study and one of the critical parts is the localization of the vehicle in the environment. Different localization methods have been studied over the years, such as the GPS sensor, commonly fused with other sensors such as the IMU. LÄS MER

  7. 5. Design and Packaging of All-in-One Axle

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Alafiya Talib; Lakshay Singhal; [2023]
    Nyckelord :E-axle; Modularity; PUGH’s Matrix; CAD-Modeling; Kinematic Analysis; Finite Element Analysis; E-axel; Modularitet; PUGHs matris; CAD-modellering; Kinematisk Analys; Finita Element Analys;

    Sammanfattning : The aim of this thesis work is to design an electric axle that contains all the operational components, like the powertrain, suspension, brakes, and steering system. One of the requirements of this design work is to package all the axle components compactly in one single unit. LÄS MER
