  1. 1. Browser Based Remote Control of Raspberry Pi enabled RC Car

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Theodor Le Brasseur; [2023]
    Keywords : ;

    Abstract : There are a variety of network technologies with different uses. Technologies such as WiFi and Ethernet are often used in for example home networks. Technologies such as Starlink make it possible to access the internet with high bandwidth and low latency globally. READ MORE

  3. 2. Detection of voids in welded joints using ultrasonic inspection : Quality control of welded joints in copper canisters for purpose of permanent storage of used nuclear waste

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Bakhtiar Afzalan; [2021]
    Keywords : Ultrasonic inspection; Nuclear waste; Nuclear waste storage; welded joints;

    Abstract : This thesis was done i cooperation with SKB Clab in Oskarshamn and studies use of sonic waves for detecting voids and irregularities in the weld joints of copper capsules used for long term storage of radioactive waste. Since these could pose material failure and thereby risk radioactive contamination of ground water it is very important to find means of quality control before storage. READ MORE

  4. 3. Simulation of ultrasonic time of flight in bolted joints

    University essay from KTH/Hållfasthetslära

    Author : David Chlebek; [2021]
    Keywords : Acoustoelastic effect; User material subroutine; Murnaghan hyperelastic material model; Explicit FEM; Ultrasonic preload; Fortran; Akustoelastiska effekten; Användar material; Murnaghan hyperelastisk materialmodell; Explicit FEM; Ultraljudsmätning av klämkraft; Fortran;

    Abstract : Ultrasonic measurements of the preload in bolted joints is a very accurate method since it does not depend on the friction and other factors which cause difficulties for common methods. The ultrasonic method works by emitting an ultrasonic pulse into the bolt which is reflected at the end and returned to the transducer, the change in the time of flight (TOF) can be related to the elongation of the bolt and therefore the preload.

  5. 4. Acoustic Droplet Vaporization : An Assessment of How Ultrasound Wave Parameters Influence the Vaporization Efficiency

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Sara Öquist; [2020]
    Keywords : Acoustic Droplet Vaporization; Verasonics; Ultrasound; Vaporization Efficiency; Phase-change Contrast Agents;

    Abstract : Acoustic droplet vaporization (ADV) is a process in which a phase shift of a liquified droplet into a gaseous microbubble, is triggered using an ultrasonic wave. In contrast to utilizing conventional contrast agents in ultrasound, the phase change contrast agents used in ADV can extravasate into tumor tissue, and they offer a greater circulatory lifespan, thereby increasing the potential applications in which they can be utilized.

  6. 5. Non-Destructive Testing Of Concrete Bridges

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Nadja Hedlund; [2020]
    Keywords : Non-Destructive testing; Concrete; Covermeter; Ultra-Sonic Pulse Velocity; Rebound hammer;

    Abstract : Non-destructive testing is of great value in cases where a structure's future is investigated to find out what the best measure is. It is not always the best solution to demolish and build new. Many structures can be repaired and function several more years. READ MORE
