  1. 1. Efficient Methods to Calculate Mutual Coupling between Generic Antennas on Large Platforms

    Författare :Johan Malmström; B. Lars G. Jonsson; Lars Pettersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis presents research on methods for calculating the mutual coupling between antennas. The mutual coupling between antennas is a measure of the amount of energy transmitted from one antenna that is received by another, and is a key parameter when installing antennas on platforms, such as aircraft.

  4. 3. Där berättelsen äger rum : Narration, perception och kognition i ett kombinerat text- och läsarperspektiv med exempel ur Eyvind Johnsons författarskap

    Författare :Ulf Pettersson; Lars Elleström; Bo G Jansson; Linnéuniversitetet; []
    Nyckelord :HUMANIORA; HUMANITIES; Intermedialitet; kognitiv poetik; narratologi; Eyvind Johnson; spatialitet; läsare; Literature; Litteraturvetenskap; Comparative literature; Litteraturvetenskap;

    Sammanfattning : I en narratologisk studie granskas spatialitet i skönlitterär prosatext. I texten undersöks några spatiala nivåer som kan länkas till extradiegetisk berättarinstans och "normal" perception kontra drömmar och visioner hos karaktärer inom diegesen. LÄS MER

  5. 4. Local Structure of Hydrogen-Bonded Liquids

    Författare :Matteo Cavalleri; Lars G.M. Pettersson; John Tse; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrogen-bond; water; ice; density functional theory; DFT; core-level spectroscopies; x-ray absorption; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Ordinary yet unique, water is the substance on which life is based. Water seems, at first sight, to be a very simple molecule, consisting of two hydrogen atoms attached to one oxygen. LÄS MER

  7. 5. Structure Modeling with X-ray Absorption and Reverse Monte Carlo: Applications to Water

    Författare :Mikael Leetmaa; Lars G M Pettersson; John Rehr; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water structure; x-ray absorption; spectroscopy; diffraction; reverse monte carlo; XAS; EXAFS; XANES; RMC; TP-DFT spectrum calculations; Physics; Fysik; kemisk fysik; Chemical Physics;

    Sammanfattning : Water is an important substance. It is part of us, of our environment, and is a fundamental prerequisite for the existence of life as we know it. The structure of water is still, after over 100 years of research on the subject, however under debate. LÄS MER
