1. 41. Linearity Enhancements of Receiver Front-end Circuits for Wireless Communication

   Författare :Mohammed Abdulaziz; Institutionen för elektro- och informationsteknik; []
   Nyckelord :CMOS; receivers; operational transconductance amplifiers; filtering; channel select filters; stability; low noise amplifiers; linearization; carrier aggregation; spectrum sensing;

   Sammanfattning : Technology scaling in advanced CMOS nodes has been very successful in reducing the cost and increasing the operating frequency, however, it has also resulted in reduced transistor intrinsic gain and increased thermal noise coefficient, and most importantly, deteriorated linearity performance. At the same time, advanced wireless communication standards offer ever increasing data rates and pose more stringent requirements on coexistence, leading to very stringent linearity requirements.

3. 42. Design Aspects of Fully Integrated Multiband Multistandard Front-End Receivers

   Författare :Adiseno; KTH; []
   Nyckelord :low-noise amplifier; mixer; RF front-end; wireless receiver; noise figure; linearity; bandwidth; dual-loop feedback;

   Sammanfattning : In this thesis, design aspects of fully integrated multibandmultistandard front-end receivers are investigated based onthree fundamental aspects: noise, linearity and operatingfrequency. System level studies were carried out to investigatethe effects of different modulation techniques, duplexing andmultiple access methods on the noise, linearity and selectivityperformance of the circuit.

4. 43. Zur Bedeutung des Vergleichs in Eichendorffs Erzählwerk : "...ihm war, als spiegelte sich wunderbar sein Leben wie ein Traum noch einmal wieder"

   Författare :Ragni Behrens; Helmut Müssener; Stefan Nienhaus; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Eichendorff; Eichendorff’s narrative work; similes; types of similes; classical similes; non-classical types of similes; if- as if-similes; adverbial similes; subject-related similes; proprium; improprium; image giver; image receiver; tropes; antique rhetoric; Middle High German epic poem; Romanticism; functions of similes; pictures in motion; sounding motion; formula; formulaic manner; synaesthesia; formulas; intertextuality; German language; Tyska språket;

   Sammanfattning : The present dissertation investigates similes and their importance in Eichendorff’s narrative work. The sources of the investigation consist of seven of Eichendorff’s narratives. Their 734 similes make up the corpus, which is presented in its entirety in the appendix. The context of the similes is partly included as well. LÄS MER

7. 45. Kommunikationsmodeller inom public relations

   Författare :Peder Jonsson; Mats Engwall; Jesper Falkheimer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; public relations; public affairs; communication models; co-orientation; sender-receiver; one-way; two-way; connectivity; network; tensegrity; stakeholder; relationship marketing; SMCR; ABX; weak ties.; Industriell ekonomi och organisation; Industrial Engineering and Management;

   Sammanfattning : Once a year for over forty years public relations’ practitioners in Sweden gathers, the political week in Almedalen, in the town of Visby. There they exchange knowledge and experience on all types of subjects using different and common communication models whether they are aware of them or not. LÄS MER
