  1. 21. Resonant and Non-Resonant Electron Spectroscopy of Free Molecules and Free Clusters

    Författare :Raimund Feifel; Michael Meyer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : Resonant electron spectroscopy has been performed on the diatomic molecules CO, N2 and HCl. Core-excitations were made to bound and dissociative intermediate electronic states. Fundamental interference phenomena are observed and discussed in the framework of ”X-ray Raman Scattering Theory”. LÄS MER

  3. 22. Multiconductor transmission lines wideband modeling : A delay-rational Green’s-function-based method

    Författare :Maria De Lauretis; Jonas Ekman; Giulio Antonini; Wil Schilders; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : The performance of variable-frequency drives (VFDs) commonly used in energy production plants can be severely affected by electromagnetic (EM) noise in the form of conducted disturbances.A VFD is composed of an inverter, a motor, and a connecting power cable. LÄS MER

  4. 23. Molecular electronic,  vibrational and rotational motion in optical and x-ray fields

    Författare :Sergey Gavrilyuk; Faris Gelmukhanov; Stephane Carniato; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-ray; nonlinear optics; photobleaching; recoil; anisotropy; Auger; Chemical physics; Kemisk fysik;

    Sammanfattning : The subject of this theoretical  study is the role ofelectronic structure as well as of rotational and vibrational motionson interactions between molecules and electromagnetic radiation,ranging from optical to x-ray. The thesis concerns both linear and nonlinear regimes of the light-matter interaction. LÄS MER

  5. 24. Functional studies of the multiple endocrine neoplasia type 1 gene

    Författare :Lovisa Bylund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEN1; menin; tumor suppressor gene; cancer; RNAi; promoter; expression; cytogenetic; microarray;

    Sammanfattning : The multiple endocrine neoplasia type 1 (MEN1, OMIM 131 100) syndrome is an autosomal dominant trait with a near 100% penetrance and with an estimated prevalence of 2-20/100 000. The syndrome is characterized by neoplasia affecting the parathyroid glands (90-97%), enteropancreatic endocrine tissues (30-80%) and the anterior pituitary gland (15-50%) but tumors arc also found in other, both endocrine and non endocrine tissues.

  7. 25. Mobility Management and Localizability for Cellular Connected UAVs

    Författare :Irshad Ahmad Meer; Cicek Cavdar; Mustafa Ozger; Ki Won Sung; Halim Yanikomeroglu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Unmanned aerial vehicles; Localization; Service availability; Air-to-ground channel; Mobility; Handover; Unmanned aerial vehicles; Localization; Service availability; Air-to-ground channel; Mobility; Handover;

    Sammanfattning : Unmanned Aerial Vehicles (UAVs) connected to cellular networks present novel challenges and opportunities in mobility management and localization, distinct from those faced by terrestrial users. This thesis presents an integrated approach, combining two key aspects essential for the integration of UAVs with cellular networks. LÄS MER
