    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

  3. 2. Growth and thermoelectric properties of CaMnO3-based thin films

    Författare :Erik Ekström; Per Eklund; Fredrik Eriksson; Biplab Paul; Erik Lewin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The field of them1oelectrics started in early 19th century. Since the discovery of the Seebeck effect and the Peltier effect, thermoelectric modules have found their way into, mostly, niche applications such as radioisotope thermoelectric generators on space missions. LÄS MER

  4. 3. Aspects on dermatan sulfate metabolism

    Författare :Erik Eklund; Matrixbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk biologi; Clinical biology; iduronic acid; galactosaminoglycan; Dermatan sulfate; biosynthesis;

    Sammanfattning : The functions of proteoglycans often depend on the fine structure of the covalently attached glycosaminoglycan (GAG) side-chains. The process leading to the mature GAG is complex and involves a multitude of different enzymatic steps. LÄS MER

  5. 4. A/D Conversion for Sensor Systems

    Författare :Jan-Erik Eklund; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Today, an important field for circuit design research is advanced mixed mode CMOS circuits for the most varying purposes. By designing these for implementation in basic and cheap digital technologies, building blocks for advanced systems are achieved. LÄS MER

  7. 5. Modeling Silicon Diode Dose Response in Radiotherapy Fields using Fluence Pencil Kernels

    Författare :Karin Eklund; Anders Ahnesjö; Erik Grusell; Hugo Palmans; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiological physics; Radiofysik; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : In radiotherapy, cancer is treated with ionizing radiation, most commonly bremsstrahlung photons from electrons of several MeV. Secondary electrons produced in photon-interactions results in dose deposition. The treatment response is low for low doses, raises sharply for normal treatment doses and saturates at higher doses.
