  1. 21. Radiographic assessment of cup migration and wear after hip replacement

    Författare :Thomas Ilchmann; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; measurement; assessment; loosening; migration; wear; cup; Hip; arthroplasty; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Methods are needed for accurate measurement of acetabular cup migration and wear after hip replacement. The EBRA (Ein Bild Röntgen Analyse) method was recently introduced as a computerized method for radiographic assessment of acetabular cup migration. LÄS MER

  3. 22. On Reduction of Substrate Noise in Mixed-Signal Circuits

    Sammanfattning : Microelectronics is heading towards larger and larger systems implemented on a single chip. In wireless communication equipment, e.g., cellular phones, handheld computers etc. LÄS MER

  4. 23. Reduction of Substrate Noise in Mixed-Signal Circuits

    Författare :Erik Backenius; Mark Vesterbacka; Kejll O. Jeppson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixed-signal; Substrate noise; Substrate modeling; Simultaneous switching noise; SSN; Digital; Analog; Clock; Electronics; Elektronik;

    Sammanfattning : In many consumer products, e.g., cellular phones and handheld computers, both digital and analog circuits are required. Nowadays, it is possible to implement a large subsystem or even a complete system, that earlier required several chips, on a single chip. LÄS MER

  5. 24. Orthopaedic measurements with computed radiography. Methodological development, accuracy, and radiation dose with special reference to the weight-bearing lower extremity and the dislocating patella

    Författare :Jan Sanfridsson; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; digital.; computer-assisted; Picture Archiving and Communication Systems; computed radiography; radiography; effective dose; radiation dosage; measurements; biomechanics; dislocating patella; musculoskeletal; patellofemoral joint; Knee joint; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : The overall aim of this study was to develop and evaluate a measurement system for computed radiography (CR) and Picture Archiving and Communication Systems (PACS), permitting measurements of long distances and angles in and between related images. The developed measurement system, which was based on the QUESTOR Precision Radiography (QPR) system, was applied to the weight-bearing knee with special reference to the dislocating patella. LÄS MER

  7. 25. Advanced Optical Diagnostics in Particle Combustion for Biomass and Metal as Alternative Fuels

    Författare :Shen Li; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical diagnostics; Quantitative measurement; Iron powder; Biomass; High-speed imaging; Digital holography; 3D reconstruction; SEM; Fysicumarkivet A:2022:Li;

    Sammanfattning : The energy sector is in urgent need for carbon-free strategies considering environmental pollutions and climate change impact. Two kinds of solid fuels, biomass and metal particles have been studied in this thesis aiming at CO2 emission reduction or zero carbon emission. LÄS MER
