  1. 1. Research and Testing of an Electromechanical solution for Vibration Assisted Drilling of Aerospace Materials

    University essay from Uppsala universitet/Solcellsteknik

    Author : Jonathan Nordenholm; [2020]
    Keywords : vibration; drilling; chips; aerospace; advanced drilling unit;

    Abstract : This thesis considers vibration drilling in aerospace materials. The tolerances of the drilled holes in aerospace industry are very low since hole quality is an important factor. Conventional methods of drilling create long ribbon formed chips that increases the heat formation and decreases the hole quality. READ MORE

  2. 2. System modelling of a tightening tool

    University essay from KTH/Teknisk mekanik

    Author : Caroline Eriksson; [2020]
    Keywords : ;

    Abstract : With the help of modern computational power it has become much more common to employ simulation driven development. When performing simulations before creating prototypes and actual test, companies can reduce both the time spent on the development and the cost. READ MORE

  3. 3. Response of Footbridges equipped with TLD : A numerical and experimental assessment

    University essay from KTH/Bro- och stålbyggnad

    Author : Silhady Tshitende Luboya; [2020]
    Keywords : Tuned liquid damper; tuned mass damper; dynamic analysis; dynamics evaluation; vibration; footbridge; human-induced vibrations; parametric study; serviceability; assessment.;

    Abstract : In recent years, an increase to design slender and aesthetically-pleasing structures have resulted in some structures having a low natural frequency. This is because the design calculation did not meet the requirement of serviceability performance. READ MORE

  4. 4. Deblurring of Cell Images Using Generative Adversarial Networks

    University essay from Lunds universitet/Matematik LTH

    Author : Ida Wagnström; Cajsa Olofsson; [2019]
    Keywords : GAN; GANs; deep learning; machine learning; focus; blur; microscopy; cellavision; microscope; generative adversarial network; Mathematics and Statistics;

    Abstract : The digital microscopes that CellaVision produces today use a mechanical auto focus when capturing cell images. This requires the camera objective to be vertically positioned with a precision of 0.4 µm in order for the objects in the images to be considered properly focused. READ MORE

  5. 5. Digital Compensation of Phase Noise Caused by Mechanical Vibrations

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Akib Mahmud; [2019]
    Keywords : ;

    Abstract : The component that generates the frequency of the radio waves transmitted by a radar is generally built around a quartz crystal oscillator. When this component is exposed to mechanical vibrations, such as acceleration or rotation in different directions, phase noise occurs. READ MORE
