1. 1. EC State aid rules : An analysis of the selectivity criterion

   Författare :Mona Aldestam; Nils Mattsson; Torbjörn Andersson; Piet J. Slot; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; European law; EC State aid; Taxation; Derogation; Benchmark; Norm; Selectivity criterion; Justifications; Europarätt; European law; EU-rätt; Jurisprudence; Allmän rättslära;

   Sammanfattning : The application of Art. 87(1) EC to taxes above all is connected to the application of the derogation method, which appears to be part of the selectivity criterion. This dissertation examines the application of the derogation method and the assessment of the selectivity criterion applied to taxes, primarily de lege lata, but also de lege ferenda. LÄS MER

4. 3. Computation of EMC Properties of Slots and Printed Circuit Boards

   Författare :Jan Carlsson; RISE; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrugations; crosstalk; FDTD; spectral domain; EFIE; chokes; Finite Difference Method; printed circuit board; transmission line network; EMC analysis; PCB; transmission line theory; radiated emission; Method of moments; MM; MoM; electric field integral equation; soft and hard surfaces; slot; radiated susceptibility;

   Sammanfattning : This thesis deals with the numerical solution of electromagnetic compatibility (EMC) problems for electronic systems, such as radiated emission, susceptibility and crosstalk on printed circuit boards and transmission through slots. The analysis of printed circuit boards is done by using an electric field integral equation (EFIE) expressed in the frequency domain, which is solved by using the method of moments. LÄS MER

5. 4. Investigating and Enhancing Performance of Multiple Antenna Systems in Compact MIMO/Diversity Terminals

   Författare :Shuai Zhang; Sailing He; Raj Mittra; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple antennas; planar inverted-F antenna; mutual coupling; slot antenna; compact antenna; mobile antenna; Q factors; antenna array; ultra-wideband UWB antenna; pattern diversity; polarization diversity; user effects; adaptive arrays; chassis mode;

   Sammanfattning : Today, owners of small communicating device are interested in transmitting or receiving various multimedia data. By increasing the number of antennas at the transmitter and/or the receiver side of the wireless link, the diversity/Multiple-Input Multiple-Output (MIMO) techniques can increase wireless channel capacity without the need for additional power or spectrum in rich scattering environments.
