1. 1. Guldår & krisår : Svensk jazz under 1950- och 60-talen

   Författare :Jan Bruér; Holger Larsen; Olle Edström; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Jazz history; interviews; vocalists; folklore influences; accordionists; Big Bands; jazz literature; discographies; record companies; repertory; myths; media; drugs; venues; Music; Musikvetenskap; Musicology; musikvetenskap;

   Sammanfattning : The purpose of this dissertation is to examine the history of jazz in Sweden during two dynamic and critical decades, the 1950s and ’60s. My analysis also discusses methodological challenges that a (Swedish) jazz historian can face. LÄS MER

3. 2. Low-Power Secondary Access to the TV and Aeronautical Bands

   Författare :Evanny Carol Obregon Gamarra; Jens Zander; Ki Won Sung; Ben Slimane; Jonas Kronander; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secondary Access; Interference Management; TV band; Aeronautical Band; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : The avalanche in mobile data consumption represents a big challenge for mobile operators. The efficient use of radio resources, e.g. technology, infrastructure and spectrum, is needed to meet the new capacity requirement in the mobile networks. LÄS MER

4. 3. New directions in RF LNA design

   Författare :Stefan Andersson; Christian Fager; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The RF field develops fast today and to meet the increasing needs from more and more users and higher and higher data rates for mobile terminals the number of wireless standards are rapidly increasing. This has lead to an increased number of frequency spectra dedicated for wireless communication, such as the recent ones for WCDMA, Bluetooth, and WLAN. LÄS MER

5. 4. On the Deployment of Large-Scale High-Capacity Wireless Systems with Secondary Spectrum Access

   Författare :Evanny Obregon; Jens Zander; Ki Won Sung; William Webb; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : The avalanche in mobile data consumption represents a big challenge for mobile networks operators and national regulators. This thesis focuses on finding additional spectrum to meet this demand in a cost-efficient way by considering shared spectrum access. LÄS MER

7. 5. A Quantum Chemical View of Molecular and Nano-Electronics

   Författare :Jun Jiang; Yi Luo; Jim Greer; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi;

   Sammanfattning : This dissertation presents a generalized quantum chemical approach for electron transport in molecular electronic devices based on Green's function scattering theory. It allows to describe both elastic and inelastic electron transport processes at first principles levels of theory, and to treat devices with metal electrodes either chemically or physically bonded to the molecules on equal footing.
