1. 11. Integrated Frequency Synthesis for Convergent Wireless Solutions

   Författare :Jad G. Atallah; Mohammed Ismail Elnaggar; Erik Bruun; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless; transceiver; Bluetooth; DECT; GSM; 3G; LTE; WLAN; WiMAX; multi-standard; vertical handover; Sniffer; frequency synthesizer; phase-locked loop; PLL; sigma-delta; calibration; Electronics; Elektronik;

   Sammanfattning : Wireless transceivers combining several standards in one unit are of key importance. In order to reach the ultimate goal of maximizing the performance-to-cost ratio of such modules, a careful study of the target application, the architecture, and the frequency planning is strongly required.

3. 12. Designing Electronic Waybill Solutions for Road Freight Transport

   Författare :Shoaib Bakhtyar; Lars Lundberg; Lawrence Henesey; Ingo Timm; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Electronic waybill; e-waybill; Intelligent transport system; ITS services; Freight transport;

   Sammanfattning : In freight transportation, a waybill is an important document that contains essential information about a consignment. The focus of this thesis is on a multi-purpose electronic waybill (e-Waybill) service, which can provide the functions of a paper waybill, and which is capable of storing, at least, the information present in a paper waybill.

4. 13. Ny väg till nya vägar och järnvägar : Finanseringspragmatism och planeringsrationalism vid beslut om infrastrukturinvesteringar

   Författare :John Hultén; Statsvetenskapliga institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; pragmatism; rationalism; railway investments; road investments; transport infrastructure; co-financing; alternative financing; investment planning; planning; Decision-making process;

   Sammanfattning : Investment planning is a decision-making process with specific characteristics. It is often seen as a rational quest for solutions that are in the public interest, and the dominant discourse tends to be technical and economic. LÄS MER

5. 14. Design and Evaluation of Anonymity Solutions for Mobile Networks

   Författare :Christer Andersson; Simone Fischer-Hübner; Thijs Holleboom; Dogan Kesdogan; Claudia Diaz; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; privacy; anonymity; anonymous overlay networks; anonymity metrics; pseudonymity; identity management; mobile Internet; location based services; mobile ad hoc networks; Computer science; Datavetenskap; Datavetenskap; Computer Science;

   Sammanfattning : Internet and mobile communications have had a profound effect on today's society. New services are constantly being deployed, in which personal data are being processed in return for personally tailored services. While mobile networks lay the groundwork for new innovative services, at the same time they pose numerous privacy challenges. LÄS MER

7. 15. Maximal Unitarity at Two Loops : A New Method for Computing Two-Loop Scattering Amplitudes

   Författare :Kasper J. Larsen; Lisa Freyhult; David Kosower; Joseph Minahan; Paul Heslop; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amplitudes; NNLO calculations; Quantum Chromodynamics; Unitarity; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : The study of scattering amplitudes beyond one loop is necessary for precision phenomenology for the Large Hadron Collider and may also provide deeper insights into the theoretical foundations of quantum field theory. In this thesis we develop a new method for computing two-loop amplitudes, based on unitarity rather than Feynman diagrams. LÄS MER
