  1. 21. A Deep-Learning-Based Approach for Stiffness Estimation of Deformable Objects

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

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

    Abstract : 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. READ MORE

  3. 22. Injectable and shape-retaining collagen hydrogel, crosslinked using bio-orthogonal cycloaddition chemistry

    University essay from KTH/Fiber- och polymerteknologi

    Author : Murtaza Sharq; [2022]
    Keywords : Injectable and shape-retaining collagen hydrogel; crosslinked using bio-orthogonal cycloaddition chemistry; Injicerbara och formbevarande kollagenhydrogeler; tvärbundna med bio-ortagonal cykloadditionskemi;

    Abstract : Under senaste decennierna, har intresset kring implantat från naturliga och syntetiska polymerer ökat markant i samband med en ökad marknadsefterfrågan på vävnadsdonationer. Detta har lett till efterforskningen av nya in-situ formerande geler med formbevarande egenskaper in-vivo. READ MORE

  4. 23. Gene expression and mechanical properties regulating two phenotypes of horse’s skin appendages: hoof strength and hair structure

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Asmaa Alameddine; [2022]
    Keywords : horse; hair; hoof quality; RNA-seq; gene expression; mechanical properties; barefoot racing;

    Abstract : Background: The hair follicle and hoof are two parts of the horse’s skin appendages that emerge from the dermis and epidermis. Different phenotypes characterize these two integument structures and determine their quality. In this project, we were interested in studying two phenotypes, the strength of the hoof and two types of horse hairs. READ MORE

  5. 24. Reliability-Based Sensitivity Analysis of the Dynamic Response of Railway Bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Hasan Al-Zubaidi; [2022]
    Keywords : Railway bridges; High-speed trains; Simply supported beam; Global sensitivity analysis; Uncertainty quantification; Reliability; Ballast instability; Running safety; Passenger comfort;

    Abstract : In response to the planned increase in operational speeds and axle loads of passengertrains that may lead to resonance-induced excessive vibrations in railway bridges,recent studies examined the reliability of bridges concerning train running safety andpassenger comfort limit states. In this respect, valuable information regarding theimportance of input variables can be obtained by conducting Sensitivity Analysis (SA). READ MORE

  6. 25. Ab inito calculation of the formation energy of the sigma phases at 1000 Kelvin : With a five sublattice model for the ternary Iron-Chromium-Nickel system

    University essay from KTH/Materialvetenskap

    Author : Fabian Mathias Veid; [2022]
    Keywords : ;

    Abstract : This project investigates the σ-phase formation energy at 1000 Kelvin using Exact Muffin TIn Orbital (EMTO) method and considers the disordered local moment approach to handle the paramagnetism in a self-consistent manner. The sigma phase is detrimental and causes embrittlement when it occurs primarily in stainless steel and superalloys with Iron (Fe) and Chromium (Cr), which is why it is necessary to understand it better and therefore avoid it.
