  2. 1. Screen Printing Technology for Energy Devices

    Author : Andreas Willfahrt; Xavier Crispin; Isak Engquist; Erich Steiner; Gunter Hübner; Tim Claypole; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; screen printing; printed electronics; energy converters; energy storage;

    Abstract : The technical application of screen and stencil printing has been state of the art for decades. As part of the subtractive production process of printed circuit boards, for instance, screen and stencil printing play an important role. With the end of the 20th century, another field has opened up with organic electronics. READ MORE

  4. 2. A study of some energy dependent characteristics of X-ray screens used in diagnostic radiology : screen-film sensitivity, MTF and some related factors

    Author : Mikael Karlsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intensifying screens; x-ray screens; fluorescent screens; modulation transfer function; MTF; x-ray screen sensitivity; fluorescent K-radiation sources;

    Abstract : Fluorescent x-ray screens are used in medical x-ray diagnostics to absorb x-ray photons and convert these x-ray photons to visible light. The light distribution from these screens are then registered on photographic film to give an x-ray image. READ MORE

  5. 3. Effects of Small-Scale Ionospheric Irregularities on GNSS Radio Occultation Signals : Evaluations Using Multiple Phase Screen Simulator

    Author : Vinícius Ludwig Barbosa; Mats Pettersson; Viet Thuy Vu; Stig Syndergaard; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GNSS Radio Occultation GNSS-RO ; Ionosphere; Scintillation;

    Abstract : Radio Occultation (RO) is a remote sensing technique which uses Global Navigation Satellite System (GNSS) signals tracked by a Low-Earth Orbit (LEO) satellite to sound the earth's atmosphere both in low (troposphere, stratosphere) and high (ionosphere) altitudes. GNSS-RO provides global coverage and SI traceable measurements of atmospheric data with high-vertical resolution. READ MORE

  6. 4. The Role of Projected Anatomy, Random Noise, and Spatial Resolution on Clinical Image Quality in Digital Mammography

    Author : Mark Ruschin; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D breast imaging; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; hybrid images; dose reduction; spatial resolution; pixel size; Breast cancer; digital mammography; radiologi; tomografi; medicinsk instrumentering; breast tomosynthesis;

    Abstract : Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. READ MORE

  7. 5. Optical Detection Using Computer Screen Photo-assisted Techniques and Ellipsometry

    Author : Jimmy W. P. Bakker; Hans Arwin; Jin Gang; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optical sensing; Biohttps: www.diva-portal.org liu webform form.jsp#paper0sensing; Ellipsometry; Computer Screen Photo-assisted Technique; Fluorescence; Immunoassays; Optics; Optik;

    Abstract : Two main subjects, ellipsometry and computer screen photo-assisted techniques (CSPT), form the main line in this thesis. Ellipsometry is an optical technique based on the detection of polarization changes of light upon interaction with a sample. READ MORE
