  1. 11. Incorporating Sparse Attention Mechanism into Transformer for Object Detection in Images

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

    Author : Cuong Duc Dao; [2022]
    Keywords : Detection Transformer; Sparse Attentions; Sparsity; Attention Mechanism; Learnable sparsity; Object Detection; Detektionstransformator; gles attention; gleshet; träningsbar gleshet; objektdetektion;

    Abstract : DEtection TRansformer, DETR, introduces an innovative design for object detection based on softmax attention. However, the softmax operation produces dense attention patterns, i.e., all entries in the attention matrix receive a non-zero weight, regardless of their relevance for detection. READ MORE

  3. 12. Evaluation, Design & Development of a Prototype 3-Link Mini Robot Manipulator

    University essay from Högskolan i Gävle/Elektronik

    Author : Rijon Ahmed; [2022]
    Keywords : Robotics; Arduino; Design;

    Abstract : A 3-link robotic arm was designed, constructed, and tested as part of the thesis work. This prototype will assist students in applying their robotics and control system theory knowledge to real results. The kinematic equations are created to help with trajectory planning. READ MORE

  4. 13. High-performance implementation of H(div)-conforming elements for incompressible flows

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Niklas Wik; [2022]
    Keywords : Finite elements; H div -conforming; incompressible flows; incompressible Navier-Stokes equations; high-performance; matrix-free; Raviart-Thomas;

    Abstract : In this thesis, evaluation of H(div)-conforming finite elements is implemented in a high-performance setting and used to solve the incompressible Navier-Stokes equation, obtaining an exactly point-wise divergence-free velocity field. In particular, the anisotropic Raviart-Thomas tensor-product polynomial space is considered, where the finite element operators are evaluated with quadrature in a matrix-free fashion using sum-factorization on tensor-product meshes.

  5. 14. On the (1/2,1/2) Representation of the Lorentz Group and the Discrete CPT Symmetries

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Nikolaj Skog Pirinen; [2021]
    Keywords : The Lorentz Group; Group Theory; Quantum Field Theory; CPT; Symmetry; Spinors; Representation Theory; Physics and Astronomy;

    Abstract : This thesis derives the explicit form of the elements of the (1/2,1/2) representation of the Lorentz group, by actually performing a direct product of the chiral (1/2,0)- and (0,1/2)-representations. The Lorentz transformations of fourvectors are thereafter recovered from this direct-product representation, allowing the derivation of a transformation matrix between the fourvector- and direct product basis.

  6. 15. Transformation Techniques to Facilitate Hardware Acceleration of Workloads

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Oscar Manuel Castro Otárola; [2021]
    Keywords : ;

    Abstract : There are many hardware and software techniques to decrease the execution time in a high workload computation program. The software techniques do not require extra hardware and could be a cheaper and easier solution. READ MORE
