    Gel Polymer Electrolytes Composed Of Ethyl Methacrylate And Methyl Methacrylate Measured At Higher Temperature
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Peterová, Soňa
    This paper is focused on the use of gel polymer electrolytes composed of copolymers ofethyl methacrylate and methyl methacrylate with positive NMC electrode (LiNi0.33Mn0.33CO0.33O2).This article describes the composition of gel polymer electrolyte, the method of preparation anddescription of the NMC electrode. The experiment is based on the measurement of capacity andimpedance at the beginning and at the end of the experiment at room temperature and at highertemperature 40 °C.

    Electrohydrodynamic Model Of Electron Microscope
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Mačák, Martin
    This work presents a complex multiphysics model of an electron microscope in ANSYSFluent software. A custom electromagnetic model was used to describe the relativistic transport ofelectrons. The model consisted of a description of an electromagnetic field, relativistic transport ofcharged particles and interactions between charged particles and solid materials. Presented resultssuggest, that the custom model can be coupled with the CFD module, which results in a possibilityof coupled simultaneous simulations of hydrodynamics, electromagnetics, and a transport of chargedparticles.

    Verification Of Modeling Approach By Using Model Of Calculable Capacitor And Determination Of Its Accuracy
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Mancl, Vlastimil
    During the creation of any sort of model the inevitable question about the model correctnessand accuracy, should always be answered. This paper proposes a simple method for modelersto prove their approach to modeling and to determine the accuracy of a simulation. The methodconsists of creating a model of calculable capacitor based on Thompson-Lampard theorem in AnsysElectronics desktop using Maxwell 3D electronics desktop. The model and its parts are described.The expected results are discussed and compared to data obtained from simulation. Problematic ofrounding edges and its influence on simulation accuracy and time is also discussed and shown on twomodels. A part of the paper is a description of how to interpret the Ansys percentage error.

    Comparison Of Measurement Methods For Characterization Of 3d Printed Lowloss Artificial Dielectric Substrate Based On Cross Unit Cell
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Kaděra, Petr
    This paper deals with the effective complex permittivity determination of low-loss 3Dprinted artificial dielectric substrate based on a cross unit cell. The two resonators working withTE011 and TM010 modes suitable for a uniaxial anisotropy determination are compared with thetransmission / reflection waveguide method. To evaluate the methods’ performance, the eigenmodeanalysis is carried out to provide precise reference values.

    Pedestrian Detector Domain Shift Robustness Evaluation, And Domain Shift Error Mitigation Proposal
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Zemčík, Tomáš
    This paper evaluates daytime to nighttime traffic image domain shift on Faster R-CNNand SSD based pedestrian and cyclist detectors. Daytime image trained detectors are applied on anewly compiled nighttime image dataset and their performance is evaluated against detectors trainedon both daytime and nighttime images. Faster R-CNN based detectors proved relatively robust, butstill clearly inferior to the models trained on nighttime images, the SSD based model proved noncompetitive.Approaches to the domain shift deterioration mitigation were proposed and future workoutlined.
