  1. 1. New optical detection methods for capillary electrophoresis, liquid chromatography and biosensors

    Författare :Anders Hanning; KTH; []
    Nyckelord :;

    Sammanfattning : .... LÄS MER

  2. 2. Weld Cracking in Precipitation Hardening Ni-based Superalloys

    Författare :Fabian Hanning; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; welding; post weld heat treatment; weldability; Nickel based superalloys; strain age cracking; weld cracking;

    Sammanfattning : Manufacturing of hot structural components for aero engines requires the materials being used to be weldable. The high demands on strength and temperature resistance make nickel based superalloys the material of choice for this application. LÄS MER

  3. 3. Weld Cracking of Precipitation Hardening Ni-based Superalloys - Investigation of repair welding characteristics and susceptibility towards strain age cracking

    Författare :Fabian Hanning; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ATI 718Plus®; Nickel-based superalloys; hot cracking; weldability; post-weld heat treatment; Gleeble; welding; weld cracking; strain age cracking; Waspaloy; Haynes 282;

    Sammanfattning : High temperature resistance and strength requirements make nickel-based superalloys the material of choice for the hot section of aero engines. Fabrication in terms of combining wrought and cast parts in the manufacturing of hot structural components enables component optimisation via the use of wrought high-strength parts, where geometrical constraints allow, and cast parts to produce complex geometries.

  4. 4. Characterisation of terahertz integrated membrane circuits

    Författare :Johanna Hanning; Chalmers University of Technology; []
    Nyckelord :waveguide width error; calibration; THz; membrane circuit; TRL; measurement uncertainty; single-flange 2-port; 220–325 GHz; cable flex; WR-03; VNA; S-parameter;

    Sammanfattning : In this thesis a novel measurement setup and thru-reflect-line (TRL) calibration kit for vector network analyser (VNA) measurements at 220 GHz to 325 GHz (WR-03) is presented. Measurements on passive membrane circuit devices under test (DUTs) show improvement in the S-parameters compared to a waveguide integrated membrane circuit setup in previous work, especially in reducing the ripples and increasing repeatability of the measurements.

  5. 5. Maximum Waiting-time Guarantee - a remedy to long waiting lists? : Assessment of the Swedish Waiting-time Guarantee Policy 1992-1996

    Författare :Marianne Hanning; Björn Smedby; Chris Ham; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health services research; Health Services Research; Waiting lists; Health Policy; Evaluation; Maximum Waiting-time Guarantee; Hälso- och sjukvårdsforskning; Health and medical services in society; Hälso- och sjukvård i samhället;

    Sammanfattning : Lengthy waiting times have been a problem in Swedish health services for many years. In 1992, Sweden implemented a national maximum waiting-time guarantee (MWG) through an agreement between the Swedish Government and the Federation of Swedish County Councils. LÄS MER
