  1. 11. Automatic control of a model elevator based on NI LabVIEW and myRIO

    University essay from Uppsala universitet/Signaler och System

    Author : Anton Storfors; [2018]
    Keywords : LabVIEW myRIO FPGA;

    Abstract : This project aims to use the myRIO embedded device with programming development software, LabVIEW, for the education of automatic control in association with the course Control Engineering (Reglerteknik) in Uppsala University.  The myRIO is a portable reconfigurable I/O (RIO) device developed by National Instruments for students to use for designing control, signal processing, robotics, and mechatronics systems.

  3. 12. A Novel Way of Measuring Inter-Person Distance: A Study Involving an Ultrasonic Measurement Device

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Selenay Simsek; [2016]
    Keywords : Pedestrian movement; evacuation experiments; inter-person distance; fundamental diagram; Technology and Engineering;

    Abstract : A Novel Way of Measuring Inter-Person Distance: A Study Involving an Ultrasonic Measurement Device The quantitative characteristics of people movement that form the fundamental diagram have an important role in the field of Fire Safety Engineering regarding evacuation. The fundamental diagram indicates the relation between crowd speed and crowd density (or inter-person distance) or flow of crowd and crowd density. READ MORE

  4. 13. Ultrasound induced cavitation and resonance amplification using adaptive feedback Control System

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Vipul. vijigiri; Taraka Rama Krishna Pamidi; [2014]
    Keywords : Acoustic cavitation; optimization; FFT analysis; pure sine excitation; Sonotrode or ultrasonic horn; High intensity ultrasound; Sound pressure level SPL Acoustic pressure field; Feedback control; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : Acoustic cavitation in fluids using high powered ultrasound has been of great interest in industries and biomedical engineering. The need for high-intensity focused ultrasound (sound with frequencies between 20 kHz to 10 MHz) and modeling of such systems has drawn great attention in engineering. READ MORE

  5. 14. Control strategies and inspection methods for welded part

    University essay from Avdelningen för maskin- och materialteknik

    Author : Divyank Baradi; [2013]
    Keywords : Visual inspection; WPS; impressions; throat size gauge; radius gauge; liquid penetrant test; magnetic particle testing; eddy current; radiography; ultrasonic PAUT TOFD ; thermography; control plan; cost per hour.;

    Abstract : Present and future demonstrator designs were used to demonstrate the quality assurance of welds. The NDT methods tested on prototype demonstrator parts are: visual inspection, radius gauges, throat size gauge, liquid-penetrant testing, magnetic particle testing and ultrasonics with pulse echo and phased array.

  6. 15. Elastic Anisotropy of Deformation Zones in both Seismic and Ultrasonic Frequencies: An Example from the Bergslagen Region, Eastern Sweden

    University essay from Geofysik

    Author : Pouya Ahmadi; [2013]
    Keywords : Elastic Anisotropy; Seismic Anisotropy; Deformation Zone; Elastic Stiffness Tensor; LDI measurements; Seismic Data;

    Abstract : Estimation of elastic anisotropy, which is usually caused by rock fabrics and mineral orientation, has an important role in exploration seismology and better understanding of crustal seismic reflections. If not properly taken care of during processing steps, it may lead to wrong interpretation or distorted seismic image. READ MORE
