  1. 1. The Best of Both Worlds : The Effects of Knowledge and Network Relationships on Performance of Returnee Entrepreneurial Firms

    Författare :Wensong Bai; Martin Johanson; Christine Holmström_Lind; Oscar Martin Martin; Olli Kuivalainen; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : In an increasingly globalized business world, international human mobility and its association with entrepreneurship presents attractive opportunities for business research. One increasingly important phenomenon in the field is returnee entrepreneurship, which is the reverse flow of migrants who acquired skills in developed countries back to their emerging-market home countries.

  3. 2. Adatoms, Quasiparticles & Photons : The Multifaceted World of Photoelectron Spectroscopy

    Författare :Martin Månsson; Ulf Otto Karlsson; Oscar Tjernberg; Maria Carmen Asensio; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; angle-resolved photoelectron spectroscopy; electronic structure; electron dynamics; semiconductor surfaces; oxides; high-temperature superconductors; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : The experimental work presented in this thesis is based on a wide assortment of very advanced and highly sophisticated photoelectron spectroscopy (PES) techniques. The objective of the present study has been to reveal and understand the electronic structure and electron dynamics in a broad spectrum of materials, ranging from wide band gap oxides, via semiconductors along with metals, and finally high-temperature superconductors.

    Sammanfattning : Digital-to-analog converters (DACs) are key building blocks in various applications including radar and wireless communications. With the exponential growth of data throughput in modern communication standards, e.g. LÄS MER

  5. 4. Periodic Structures with Higher Symmetries: Analysis and Applications

    Författare :Fatemeh Ghasemifard; Martin Norgren; Oscar Quevedo-Teruel; Guido Valerio; Stefano Maci; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; periodic structures; higher symmetries; dispersion analysis; mode matching; generalized Floquet theorem; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In this thesis, periodic structures with higher symmetries are studied. Their wave propagation characteristics are investigated and their potential applications are discussed. Higher-symmetric periodic structures are described with an additional geometrical operation beyond a translation operator.
