  1. 1. Analytiska modeller för beräkning av tjällaster mot spontkonstruktioner

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :STAFFAN NORRTHON RISBERG; NAIMA OZIMS; [2023]
    Nyckelord :;

    Sammanfattning : I kalla klimat kan stödkonstruktioner utsättas för lastökningar till följd av tjälande jord. Tjälen bildas när vattnet i jorden fryser, och leder ofta till en volymexpansion i marken. Om tjälexpansionen förhindras bildas ett tjältryck, som kan bli så pass kraftigt att stödkonstruktioner riskerar att gå till brott. LÄS MER

  3. 2. Synthesizing of brain MRE wave data

    Master-uppsats, KTH/Medicinsk avbildning

    Författare :Maryia Yuliuhina; [2023]
    Nyckelord :MR elastography; brain MRE; synthetic data; computational modeling; shear wave elastography; MR-elastografi; hjärn MRE; syntetiska data; beräkningsmodellering; skjuvvåg elastografi;

    Sammanfattning : Magnetic resonance elastography (MRE) is an imaging technique that allows for non-invasive access to the physical properties of body tissues. MRE has great potential, but it is difficult to conduct research due to the time-consuming estimation of stiffness maps, which could be speeded up by using neural network. LÄS MER

  4. 3. A Deep-Learning-Based Approach for Stiffness Estimation of Deformable Objects

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

    Författare :Nan Yang; [2022]
    Nyckelord :Robotic grasping; Deformable objects; Deformation modeling; Stiffness estimation; Deep learning; Robotgrepp; Deformerbara föremål; Deformationsmodellering; Styvhetsuppskattning; Djup lärning;

    Sammanfattning : Object deformation is an essential factor for the robot to manipulate the object, as the deformation impacts the grasping of the deformable object either positively or negatively. One of the most challenging problems with deformable objects is estimating the stiffness parameters such as Young’s modulus and Poisson’s ratio. LÄS MER

  5. 4. Tyre Performance Estimation during Normal Driving

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Marcus Grip; [2021]
    Nyckelord :tyre performance; tread wear; tyre wear; online estimation; friction performance; velocity performance; friction potential; longitudinal stiffness; tyre stiffness;

    Sammanfattning : Driving with tyres not appropriate for the actual conditions can not only lead to accidents related to the tyres, but also cause detrimental effects on the environment via emission of rubber particles if the driving conditions are causing an unexpectedly high amount of tread wear. Estimating tyre performance in an online setting is therefore of interest, and the feasibility to estimate friction performance, velocity performance, and tread wear utilizing available information from the automotive grade sensors is investigated in this thesis.
