  1. 1. Regularizing Vision-Transformers Using Gumbel-Softmax Distributions on Echocardiography Data

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

    Författare :Alfred Nilsson; [2023]
    Nyckelord :Deep Learning; Vision-Transformers; Echocardiography; Feature Selection; Gumbel-Softmax; Concrete Autoencoders; Regression; Djupinlärning; Vision-Transformers; Ekokardiografi; Feature Selection; GumbelSoftmax; Concrete Autoencoders; Regression;

    Sammanfattning : This thesis introduces an novel approach to model regularization in Vision Transformers (ViTs), a category of deep learning models. It employs stochastic embedded feature selection within the context of echocardiography video analysis, specifically focusing on the EchoNet-Dynamic dataset. LÄS MER

  3. 2. An investigation on the possibility for bandwidth improvement of dielectric antennas via modification of their geometry

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

    Författare :Nandan Dutta Chaudhury; [2020]
    Nyckelord :Multifunctional antenna array; AESA; Additive manufacturing; Stereolithography; Ultra-wideband antenna; Dielectric antenna; Embedded DRA; PSF; Multifunktionell antenngrupp; AESA; Additiv tillverkning; Stereolitografi; Ultrabredbandig antenn; Dielektrisk antenn; Inbäddad DRA; PSF;

    Sammanfattning : The dielectric antenna is an interesting alternative to a metallic antenna. This is mainlydue to its low manufacturing cost and the possibility to fabricate complex antennageometry with the aid of additive manufacturing (AM). Sophisticated AM technologyprovides new degrees of freedom in shaping the outer and inner geometry of antennas. LÄS MER

  4. 3. In the middle of the implementation of the risk assessment tool RAMP: A case study at Scania AB

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Lisa Linhardt; [2015]
    Nyckelord :;

    Sammanfattning : The RAMP tool was developed at KTH and is used to risk assess Human Factors and Ergonomic (HFE) within manual handling. This master thesis study how the start of the implementation of the RAMP tool at Scania AB went, what difficulties did exist in the implementation and what went well. LÄS MER

  5. 4. Minding the spectrum gaps : First steps toward developing a distributed white space sensor grid for cognitive radios

    Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)

    Författare :Javier Lara Peinado; [2013]
    Nyckelord :cognitive radio; cooperative spectrum sensing; energy detector; kognitiv radio; kooperativa spektrum avkänning; energi detektor;

    Sammanfattning : The idea that the radio spectrum is growing ever more scarce has become commonplace, and is being reinforced by the recent bidding wars among telecom operators. New wireless applications tend to be deployed in the relatively narrow unlicensed frequency bands, worsening the problem of interference for all users. LÄS MER
