  1. 21. Design of Autonomous Underwater Vehicle’s (AUV) Antenna System

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

    Author : Chengzhuang Zhou; [2021]
    Keywords : AUV Antenna; Printed Dipole Antenna; Broadband Antenna; AUV antenna; Printed dipole antenna; Broadband antenna;

    Abstract : The ocean symbolizes mystery, passion, and power. However, most of the ocean, about 80 %, is unknown to humans. AUVs (Autonomous Underwater Vehicles) provide a platform where terrain mapping, the biodiversity, and the resource survey of the ocean become accessible. READ MORE

  3. 22. Characterization of Agarose Microdroplet Properties for Acoustic Trapping of Encapsulated Bacteria and On-chip DNA Extraction

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Tinde Höjer; [2021]
    Keywords : ;

    Abstract : The aim of this project was to investigate if the translation of a DNA extraction protocol to on-chip, for the purpose of reducing the total assay time, would be possible. This was to be enabled by encapsulating bacteria in hydrogel microdroplets that would then be acoustically trapped in a microfluidic system. READ MORE

  4. 23. Role of damping in NVH CAE procedures

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Rahul Sharma; [2021]
    Keywords : NVH; CAE; Damping;

    Abstract :   Automotive manufacturers currently face a challenge with expeditious enhancement of the vibro-acoustic properties of their vehicles. A major reason for this setback is the limited design information available during initial development stages added with limited knowledge of damping within complex structures. READ MORE

  5. 24. Shape optimization of axial cooling fan via 3D CFD simulation and surrogate modeling

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Martin Granlöf; [2021]
    Keywords : Fan noise; shape optimization; mesh morphing; computational fluid dynamics; computational aeroacoustics; Efficient Global Optimization; Reynolds-averaged Navier-Stokes;

    Abstract : Due to legislative reasons and environmental concerns the automotive and transport sector are shifting their focus from traditional internal combustion engine (ICE) vehicles to development of battery electric vehicles (BEVs). This brings new challanges to design of cooling systems where axial fans are one of the key components. READ MORE

  6. 25. Acoustic trapping of sub-micrometreparticles within microfluidics particles within microfluidics

    University essay from Uppsala universitet/Mikrosystemteknik; Uppsala universitet/Polymerkemi

    Author : Björn Stenestam; [2021]
    Keywords : ;

    Abstract : The aim of this project was to prove that a pre-existing standardmethod for bacterial-DNA extraction can be reduced down to the microscale and in doing so be used in an on-chip setting.The first phase in this project was to identify an appropriate methodand material for droplet generation.
