1. 1. Cold-Electron Bolometers fabricated with Direct Write Technology for Microwave Receiver systems

   Författare :Ernst Otto; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis concerns the development of microwave detector technology for cosmology instruments and THz imaging, including fabrication of SIN tunnel junctions for thermometry and bolometric detectors, and also phase switch circuits as a part of integrated microwave receiver systems. Cold-Electron Bolometers (CEB) based on Superconductor-Insulator-Normal metal (SIN) tunnel junctions have been developed for employment in sub-millimeter astronomical receivers. LÄS MER

4. 3. From Putsch to Purge. A Study of the German Episodes in Richard Hughes’s The Human Predicament and their Sources

   Författare :Ivo Holmqvist; Engelska; []
   Nyckelord :HUMANIORA; HUMANITIES; Weimar Republic; Documentary novel; English historical fiction; The Wooden Shepherdess; The Fox in the Attic; 1900-1976; Hughes; Richard; Rise of Nazism; Hitler portraits in literature; English language and literature; Engelska språk och litteratur ;

   Sammanfattning : The two last novels by Richard Hughes (1900-1976), the first in his planned The Human Predicament series, are partly set in Germany in the years between the First and the Second World War. Much of the action in The Fox in the Attic (1961) takes part in and around Munich, culminating in a fictional reconstruction of the so-called Hitler Putsch on November 8-9, 1923, the future dictator's aborted early bid for power.

5. 4. Syntes och design : Den intellektuelle politikern som konstnär

   Författare :Rune Gustafsson; Statsvetenskapliga institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; the heritage of forms; individuation; artistic transference; conceptual histories; political design; frame reflection; integrative complexity; the intellectual politician; synthesis; design; Political and administrative sciences; Statsvetenskap; förvaltningskunskap;

   Sammanfattning : A new theory on the intellectual politician, which has the ability to produce a designed type of problem-solving, has been developed from political science theory, cognitive theory as well as art theory. A cognitive concept, modified integrative complexity, consisting of four sub-concepts, frame reflection, differentiation, reframing and integration has been developed. LÄS MER
